#1 What causes elevated cholesterol and what
can be done to reduce it?
Elevated serum cholesterol is called
Cholesterolemia. The first set of suggestions indicates diet is the
best method to reduce cholesterol. Vegetarians typically have the
lowest cholesterol levels from their nutritional effect. Supplements
also may be employed to reduce cholesterol if dietary interventions
are not fully employed. Approximately 30% of the body's cholesterol
content is derived from dietary sources while another 50% of
cholesterol is reabsorbed through the gut, and the remainder passes
through the body unused and is excreted (via
the bile).

Cholesterol
(A
little is good, but excess is not good.) |
Regulating Cholesterol Synthesis
Normal healthy adults synthesize cholesterol
at a rate of approximately 1g/day and consume approximately
0.3g/day. A relatively constant level of cholesterol in the body
(150-200 mg/dL) is maintained primarily by controlling the level of
de novo synthesis. The level of cholesterol synthesis is
regulated in part by the dietary intake of cholesterol. Cholesterol
from both diet and synthesis is utilized in the formation of
membranes and in the synthesis of the steroid hormones and bile
acids (see below). The greatest proportion
of cholesterol is used in bile acid synthesis.
The cellular supply of cholesterol is
maintained at a steady level by three distinct mechanisms:
- Regulation of HMGR activity and levels
- Regulation of excess intracellular free cholesterol through
the activity of acyl-CoA:cholesterol acyltransferase, ACAT
- Regulation of plasma cholesterol levels via LDL
receptor-mediated uptake and HDL-mediated reverse transport.
Regulation of HMGR activity is the primary
means for controlling the level of cholesterol biosynthesis. The
enzyme is controlled by four distinct mechanisms: feedback
inhibition, control of gene expression, rate of enzyme degradation
and phosphorylation-dephosphorylation.
The first three control mechanisms are exerted
by cholesterol itself. Cholesterol acts as a feedback inhibitor of
pre-existing HMGR as well as inducing rapid degradation of the
enzyme. The latter is the result of cholesterol-induced
polyubiquitination of HMGR and its degradation in the proteosome
(see proteolytic
degradation). This ability of cholesterol is a consequence of
the sterol-sensing domain, SSD of
HMGR. In addition, when cholesterol is in excess the amount of mRNA
for HMGR is reduced as a result of decreased expression of the gene.
The mechanism by which cholesterol (and other sterols) affect the
transcription of the HMGR gene is described below under regulation
of sterol content. Regulation of HMGR through covalent
modification occurs as a result of phosphorylation and
dephosphorylation. The enzyme is most active in its unmodified form.
Phosphorylation of the enzyme decreases its activity. HMGR is
phosphorylated by AMP-activated protein kinase, AMPK (this is not the same as
cAMP-dependent protein kinase, PKA). AMPK itself is activated via
phosphorylation. The phosphorylation of AMPK is catalyzed by one or
more AMPK kinases (AMPKKs). Visit AMPK: The
Master Metabolic Regulator for more detailed information on the
role of AMPK in regulating metabolism.

Regulation
of HMGR by covalent modification. HMGR is most active in the
dephosphorylated state. Phosphorylation is catalyzed by
AMP-activated protein kinase, AMPK, (used to be termed HMGR
kinase), an enzyme whose activity is also regulated by
phosphorylation. Phosphorylation of AMPK is catalyzed by AMPK
kinase (AMPKK). Hormones such as glucagon and epinephrine
negatively affect cholesterol biosynthesis by increasing the
activity of the inhibitor of phosphoprotein phosphatase
inhibitor-1, PPI-1. Conversely, insulin stimulates the removal
of phosphates and, thereby, activates HMGR activity.
Additional regulation of HMGR occurs through an inhibition
of its'
activity as well as of its' synthesis by elevation in
intracellular cholesterol levels. |
The activity of HMGR is additionally controlled
by the cAMP-signaling pathway. Increases in cAMP lead to activation
of cAMP-dependent protein kinase, PKA. In the context of HMGR
regulation, PKA phosphorylates phosphoprotein phosphatase
inhibitor-1 (PPI-1) leading to an increase in its' activity. PPI-1
can inhibit the activity of numerous phosphatases including protein
phosphatase 2C and HMG-CoA reductase phosphatase, which remove
phosphates from AMPK and HMGR, respectively. This maintains AMPK in
the phosphorylated and active state, and HMGR in the phosphorylated
and inactive state. As the stimulus leading to increased cAMP
production is removed, the level of phosphorylations decreases and
that of dephosphorylations increases. The net result is a return to
a higher level of HMGR activity.
Since the intracellular level of cAMP is
regulated by hormonal stimuli, regulation of cholesterol
biosynthesis is hormonally controlled. Insulin leads to a decrease
in cAMP, which in turn activates cholesterol synthesis.
Alternatively, glucagon and epinephrine, which increase the level of
cAMP, inhibit cholesterol synthesis. The ability of insulin to
stimulate, and glucagon to inhibit, HMGR activity is consistent with
the effects of these hormones on other metabolic pathways. The basic
function of these two hormones is to control the availability and
delivery of energy to all cells of the body.
Long-term control of HMGR activity is exerted
primarily through control over the synthesis and degradation of the
enzyme. When levels of cholesterol are high, the level of expression
of the HMGR gene is reduced. Conversely, reduced levels of
cholesterol activate expression of the gene. Insulin also brings
about long-term regulation of cholesterol metabolism by increasing
the level of HMGR synthesis.
The
Utilization of Cholesterol
Cholesterol is transported in the plasma
predominantly as cholesteryl esters associated with lipoproteins.
Dietary cholesterol is transported from the small intestine to the
liver within chylomicrons. Cholesterol synthesized by the liver, as
well as any dietary cholesterol in the liver that exceeds hepatic
needs, is transported in the serum within LDLs. The liver
synthesizes VLDLs and these are converted to LDLs through the action
of endothelial cell-associated lipoprotein lipase. Cholesterol found
in plasma membranes can be extracted by HDLs and esterified by the
HDL-associated enzyme LCAT. The cholesterol acquired from peripheral
tissues by HDLs can then be transferred to VLDLs and LDLs via the
action of cholesteryl ester transfer protein (apo-D) which is
associated with HDLs. Reverse cholesterol
transport allows peripheral cholesterol to be returned to the
liver in LDLs. Ultimately, cholesterol is excreted in the bile as
free cholesterol or as bile salts following conversion to bile acids
in the liver.

I do not recommend all of the above, all at once, but please note
some of these may improve current blood lipid profiles and reduce
unhealthy elevated cholesterol. I do recommend reducing excess
intake of Omega-6 Linoleic Acid, which reduces Omega-3 Linolenic
Acid and increases the susceptibility of LDL-cholesterol to
oxidation, and reducing foods high in cholesterol. Keep in mind
our body requires a little, but only 4-calories worth of 1-gram of
cholesterol daily. The
standard reference range for Serum Cholesterol varies between
laboratories.The following are representative values:
1.
Less
than 200 mg/dL (>5.2 mmol per liter) (recommended desirable
range)
2.
Between
200 -239 mg/dL (5.2 - 6.2 mmol per liter) (borderline
range)
3.
Standard
reference ranges often differ dangerously from optimal
levels.Persons striving for optimal health should aim for Serum
Cholesterol levels of 180 - 220 mg/dL
4.
Serum
Cholesterol levels below 160 mg/dL is considered sub-optimal
(persons with sub-optimal Cholesterol levels have a greater
incidence of Stroke, Lung Ailments, some types of Cancer and
Alcoholism).
5.
Persons
consuming a plant-based diet are reported to post the low, but
optimal ranges of serum cholesterol resulting in optimum
cardiovascular health.
#2 What increases serum triglycerides?
Fructose is
incorporated into triglycerides more readily than glucose. Fructose
has a greater propensity to increase serum triglycerides as compared
to glucose, especially in diabetes mellitus patients and those with
blood sugar disorders. Insulin stimulates the conversion of glucose
(blood sugar) to triglycerides for storage within adipose tissue.
Excessive circulating glucose (blood sugar) is converted to glycerol
and stored within the body as triglycerides. Excessive consumption
of sucrose increases
the body's production of triglycerides (due to the body converting
excessive sucrose into triglycerides in order to protect itself from
the toxic effects of excessive sucrose).
Cafestol, a
diterpene lipid found in unfiltered coffee, increases serum
triglycerides levels.
Excessive consumption of
dietary fats may also
increase serum triglyceride levels - 95% of dietary fatty acids are
consumed in the form of triglycerides.
Trans-fatty acids increase
triglyceride levels by up to 47%.
Alcohol (ethanol)
increases the endogenous production of triglycerides. Liver cells
eliminate the excess hydrogen formed from the breakdown of alcohol
by utilizing it to form alpha-glycero-phosphates and fatty acids,
which are immediate precursors for
triglycerides.
Synthesis of Triglycerides
Fatty acids are stored for future use as
triacylglycerols in all cells, but primarily in adipocytes of
adipose tissue. Triacylglycerols constitute molecules of glycerol to
which three fatty acids have been esterified. The fatty acids
present in triacylglycerols are predominantly saturated. The major
building block for the synthesis of triacylglycerols, in tissues
other than adipose tissue, is glycerol. Adipocytes lack glycerol
kinase, therefore, dihydroxyacetone phosphate (DHAP), produced
during glycolysis, is the precursor for triacylglycerol synthesis in
adipose tissue. This means that adipoctes must have glucose to
oxidize in order to store fatty acids in the form of
triacylglycerols. DHAP can also serve as a backbone precursor for
triacylglycerol synthesis in tissues other than adipose, but does so
to a much lesser extent than glycerol.
The glycerol backbone of triacylglycerols is
activated by phosphorylation at the C-3 position by glycerol kinase.
The utilization of DHAP for the backbone is carried out through the
action of glycerol-3-phosphate dehydrogenase, a reaction that
requires NADH (the same reaction as that used in the glycerol-phosphate
shuttle). The fatty acids incorporated into triacylglycerols are
activated to acyl-CoAs through the action of acyl-CoA synthetases.
Two molecules of acyl-CoA are esterified to glycerol-3-phosphate to
yield 1,2-diacylglycerol phosphate (commonly identified as phosphatidic acid). The phosphate is then
removed, by phosphatidic acid phosphatase, to yield
1,2-diacylglycerol, the substrate for addition of the third fatty
acid. Intestinal monoacylglycerols, derived from the hydrolysis of
dietary fats, can also serve as substrates for the synthesis of
1,2-diacylglycerols.
COMMENT: Processed foods, processed sugars,
too much cooked dietary fats, transfats, and alcohol are the
culprits that raise triglycerides and have no place nor need in
healthy human nutritional pathways.
#3
How does training effect carbohydrate
metabolism? The
effect of a 6-wk training period on the oxidation of a 100-g glucose
load given orally during exercise was investigated in six healthy
male volunteers. The subjects were submitted before and 24 h after
the training program to a 105-min exercise bout (performed at about
40% of the pretraining VO2max) followed by a 90-min resting period.
Naturally labeled [13C]glucose was given 15 min after the beginning
of exercise. Exogenous glucose oxidation was derived from 13CO2
measurements in expired air, and total glucose and lipid oxidation
were evaluated by indirect calorimetry. Training (60-min bicycling 5
days a week at 30-40% VO2max) resulted in a +29% increase in VO2max.
During the 15 min of exercise that
preceded glucose ingestion, the rate of total carbohydrate oxidation
was slightly decreased after training, whereas the rate of lipid
oxidation was slightly increased. Training did not affect the
response of blood glucose, plasma insulin, or plasma free fatty
acids to the glucose ingested during exercise; in contrast, the
circulating levels of epinephrine, glycerol, and lactate were
significantly reduced after training. Substrate utilization
measurements revealed similar oxidation rates of carbohydrates
(106.9 ± 2.7 before vs. 100.2 ± 4.7 g/3
hours after training) and of lipids. However, detailed analysis revealed a
significant +17% increase in exogenous glucose oxidation, thus
indicating a significant sparing of endogenous carbohydrates.
In conclusion, physical training induces a modest but significant
increase in the oxidation of an oral load of glucose given during
subsequent exercise of moderate intensity, a phenomenon reinforcing
the sparing of endogenous carbohydrate stores (1).
COMMENT:
Training for 6 weeks by bicycling 5 days a week at 30-40% VO2max
rate resulting in a +29% increase in VO2max indicates that these
subjects were healthy normal, but not highly trained. This observed
training adaptation (at a very easy pace) increased the rate the
body spared its muscle glycogen reserves (endogenous carbohydrate
stores) and better utilized the oral carbohydrates (exogenous)
consumed.Training effects increased more of the 100 g glucose load
consumed during the 105-minute exercise bout (1.02-1.06 carbohydrate
grams/minute). Note sparing muscle glycogen delays time to fatigue
as fitness adaptations occur. References (1)

#4 What specifically causes loss of muscle
mass (sarcopenia) with aging?
Aging-related sarcopenia is defined and
characterized by a loss of muscle mass and strength and increased
fatigability. However, studies of its determinants in elderly men
are scarce.
Researchers (1) analyzed 845 men aged 45-85 y
who belonged to the MINOS cohort. Lifestyle factors (physical
activity, tobacco smoking, alcohol intake, caffeine intake) were
evaluated by using a standardized questionnaire. Appendicular
skeletal muscle mass (ASM) was estimated by using dual-energy X-ray
absorptiometry. The RELATIVE APPENDICULAR SKELETAL MUSCLE MASS INDEX
(RASM) was calculated as ASM/body height2.3. Apparent free
testosterone concentration (AFTC) and free testosterone index (FTI)
were calculated on the basis of concentrations of total testosterone
and sex hormone-binding globulin.
RASM decreased with age (r = -0.29, P <
0.0001). Current smokers had lower RASM than did subjects who never
smoked (-3.2%; P < 0.003). RASM increased with the intensity of
physical activity at work (P for trend < 0.001). Men who
participated in regular exercise during leisure time had 2.2% higher
RASM than did those who did not (P < 0.03). Men whose values for
AFTC, FTI, or 25-hydroxycholecalciferol [25(OH)D] were >2 SDs
below the mean for young men had significantly lower RASM than did
men with higher values. Men with sarcopenia, defined as the lowest
quartile of RASM in the studied cohort (<6.32 kg/m2.3), were
significantly older than men with normal RASM, weighed significantly
less, smoked more, and spent significantly less time on leisure-time
activities. Sarcopenic men also had lower values for testosterone,
AFTC, FTI, and 25(OH)D.
In elderly men, low physical activity, tobacco
smoking, thinness, low testosterone (AFTC and FTI), and decreased
25(OH)D concentrations are risk factors for sarcopenia.
COMMENT: With increasing age, smoking, low
exercise, low testosterone, low 25-hydroxycholecalciferol are
factors associated with the result of lean muscle mass loss in male
subjects. Calcidiol (25(OH)D3) is metabolized by several forms of
Vitamin D. It is the major circulating form of Vitamin D as the
first intermediate form of Vitamin D synthesized during the
conversion of Vitamin D3 to Calcitriol. Vitamin D3 is transported to
the Liver for conversion to Calcidiol by Vitamin D-binding protein.
Calcidiol is manufactured in the liver from its precursor, Vitamin
D-3. Sarcopenia rate is 20% of all elderly males and 30% of all
elderly females, but in some populations, it may be as high as 1 out
of every 2 persons. I have a paper currently in peer-reviewed in
which I analyzed a 70-120-food item intake consumed by 20 subjects,
(10 men and 10 women, 16 were athletes, 4 were sedentary). Of those
subjects, 19 of the subjects (10 women, 9 men) were not consuming
the Reference Daily Intake RDI-preventative deficiency-disease dose
of vitamin D3 through whole foods consumed. Only one subject, an
active male athlete was consuming an adequate Reference Daily Intake
RDI-preventative deficiency-disease dose of vitamin D3. Unless these
factors are addressed in terms of activity, menu, and lifestyle
choices, loss of lean muscle mass will result higher than is best
for optimal health.
THE SUBSTANCES/FACTORS THAT ENHANCE MUSCLE GROWTH
Alpha-Ketoglutarate
(such as the AKG in Race Caps Supreme) is speculated
to enhance muscle growth can reverse muscle wasting in hospital
patients by increasing glutamine stores within the
muscles.
Arginine facilitates Muscle Growth (by
inhibiting Muscle Loss - i.e. it is
Anti-Catabolic).
Supplemental Branched Chain Amino Acids (BCAAs) (when
used in conjunction with isotonic exercise (Weight lifting)
facilitate muscle growth. Supplemental BCAAs help to minimize the
body's need to catabolize endogenous BCAAs from muscles during
isotonic exercise (and other forms of exercise) by providing an
alternate source of BCAAs for the body to convert to alanine. By
preventing the catabolism of BCAAs from muscles, muscle BCAA levels
are preserved and muscle growth is not impaired. BCAAs are found in Hammer Gel, Hammer Whey,
Hammer Soy, Sustained Energy, and Perpetuem.
HAMMER WHEY
PROTEIN facilitates muscle growth by increasing the
body's retention of nitrogen - nitrogen retention from whey protein
is believed to be sixteen times that of free amino acids and twice
that of whole food (primarily due to the lactalbumin content of whey
protein). Glutamine stimulates the
synthesis of endogenous proteins within the muscles, thereby
facilitating muscle growth (i.e. It is anabolic). Glutamine can also
prevent the breakdown of proteins within the muscles (i.e. It can
prevent catabolism) during intensive exercise. It also improves
muscle growth by increasing muscle cell volumization (increasing the
retention of water within muscle fibers). Six grams glutamine is contained in every
serving of Hammer Whey.
HAMMER SOY
PROTEIN (indirectly) facilitates Muscle Growth (by
enhancing nitrogen retention which helps to prevent the catabolism
of endogenous Proteins in the Muscles). Preliminary research shows
that Daidzein facilitates muscle
growth (but only in men - it
appears to inhibit muscle growth in women). Methoxyflavone is
claimed to facilitate muscle growth.
Sleep is
essential to muscle growth (inadequate sleep causes the body's
testosterone levels to decline and human growth hormone (hGH) is
released during sleep). REM Caps are
designed to enhance deep REM sleep state cycle to increase hGH
release during sleep.
Superunsaturated
fatty acids facilitate muscle growth (when used in
conjunction with isotonic exercise) - due to their ability to
increase nitrogen retention. Fish oil
DHA/EPA and Omega-3 Flaxseed oils meet and exceed this requirement
at between 4-6 grams per day.
Calcium
(600-1,000 mg per day) facilitates muscle growth in athletes: in one
study basketballers who supplemented with 600-1,000 mg of calcium
carbonate or calcium citrate per day recorded a 3.2% increase in
muscle mass after 12 months compared to a 1.2% increase in muscle
mass in control subjects. Calcium is
formulated in Premium Insurance Caps and
Endurolytes.
Hydroxy Methylbutyrate (HMB), Ketoisocaproate
(KIC), Isoleucine, Leucine, Ornithine Alpha-Ketoglutarate (OKG),
Colostrum (Bovine Colostrum), Orotic Acid, Valine, Serine, Proline,
are protein-like amino acid safe supplements each have been shown to
facilitate muscle growth.
THE SUBSTANCES/FACTORS THAT INHIBIT LEAN MUSCLE MASS GROWTH
Excessive corticosterone causes the
proteolysis (catabolism) of endogenous proteins in the muscles -
this impedes muscle growth.
Animal and dairy byproducts may result in
excessive production of Prostaglandin E2 (PGE2) stimulates the
degradation (catabolism) of skeletal muscle, which inhibits muscle
growth.
Ibuprofen, Paracetamol, Cortisol (stress-induced) interferes with
the ability of isotonic exercise (body building) to stimulate muscle
growth.
Endurance exercise reduces muscle growth (i.e.
It causes muscle loss).
HARMFUL SUBSTANCES TO AVOID ENHANCE MUSCLE GROWTH
AVOID all "Androgen-like substances" that may
stimulate the formation of new myofilaments (the contractile
filaments in muscle) and cause enlarging myofibrils (muscle cells)
to divide. Androgen-class (male steroid hormones) that stimulate
muscle growth (in the presence of isotonic exercise (weight-bearing
exercise) such are: Luteinizing Hormone Releasing Hormone (LHRH),
Human Growth Hormone, Beta-2 Adrenergic Receptor Agonists (e.g.
Salbuterol), Insulin, pharmaceutical Chorionic Gonadotrophic Hormone
(CGH), Follicle Stimulating Hormone (FSH), Dehydroepiandrosterone
(DHEA) Testosterone, Androstenedione, Androstenediol,
Norandrostenedione, 7-Keto DHEA, Anabolic-Androgenic Steroids
(A-ASs) stimulate muscle growth (but possess numerous toxic side
effects when used chronically). I do not recommend these or the
temporal periodic use of these substances due to ethics of sport and
unpredictable health-safety issues downstream effects on the
body.

#5 What causes fat-weight gain
what can be done to prevent or reverse it?
Obesity is a state characterized
by excess adipose tissue (body fat). The term obesity is applied to
persons who are more than 20% above their recommended body weight as
measured by body mass index (BMI). Another means of determining
obesity is the waist-to-hip ratio.
A healthy body fat percentage for
women is 20% to 30% and for men a healthy body fat percentage is 8%
to 20%. One pound of human fat contains 3,500
calories.

At some stage, 78% of women and
40% of men (in western nations) have attempted to lose weight
through dieting. Fasting or dieting can actually cause weight gain
due to the fact that these practices decrease the body's basal
metabolic rate. They fool the body into "thinking" that it is
starving which results in the body conserving energy in the form of
adipose tissue. Overeating in only 10% of cases causes obesity - in
the remaining 90% important nutrients are lacking in the diet. Diet
Restriction reduces the risk of Obesity. Monkeys fed a
calorie-restricted diet for 15 years exhibited a reduced rate of
Obesity. Fasting (especially prolonged Fasting) facilitates weight
loss in persons afflicted with Obesity. Weight loss while fasting
can reach 1.1 kg per day during the first ten days of fasting and
stabilizes at 0.36 to 0.47 per kg at the end of the first month.
Fasting is NOT recommended as a viable means of attaining permanent
weight reduction for Obesity patients as it also results in loss of
Lean Body Mass and negative Nitrogen Balance. During the first month
of fasting, nitrogen losses average 4 grams per day and stabilize at
2.4 grams per day. During the first two weeks of fasting,
approximately 40% of weight loss is from water losses, protein
(muscle) loss accounts for approximately 6-10% of weight loss and
body fat (adipose tissue) loss accounts for the remaining 50-54% of
weight loss.
CAUSES OF
OBESITY
AGE: The risk of obesity increases
in tandem with the progression of the aging
process.
DIET: A high-Glycemic Index diet
increases the risk of obesity (by increasing insulin levels, which
in turn suppresses the "burning" of body fat for the production of
energy and redirects glucose to be stored as body
fat.
Holt, S., et al.
Interrelationships among postprandial satiety, glucose and insulin
responses and changes in subsequent food intake. Eur J Clin
Nutr.50:788-797, 1996.
Sigal, R., et al. Acute
postchallenge hyperinsulinemia predicts weight gain: a prospective
study. Diabetes. 46:1025-1029, 1997.
Excessive consumption of dietary
carbohydrates especially simple sugars such as glucose and sucrose
especially exacerbate obesity (by substituting for dietary fats and
adipose tissue in the body's production of energy).Dietary
carbohydrates that are not used in the production of energy are
eventually stored as body fat (adipose
tissue).
Excessive consumption of dietary
fats increases the risk of obesity (to a greater extent than an
equivalent number of calories ingested from proteins or
carbohydrates). The ingestion of dietary fats initiates a process
that results in the deposition of triglycerides (derived from the
fatty acids in dietary fats) in adipose tissues - i.e. The body
"prefers" to store dietary fats in adipose tissue in preference to
utilizing them for the endogenous production of energy (this process
is known as lipogenesis). Dietary fats can be readily incorporated
into the triglycerides of adipose tissue due to the fatty acids in
dietary fats being a principal component of
triglycerides.
Unlike calories derived from other
sources, calories derived from dietary fats require very little
endogenous energy to be expended in digesting and metabolizing them,
therefore ingestion of dietary fats do not increase the body's Basal
Metabolic Rate (BMR) to the extent that calories derived from other
sources do. Long-chain saturated fatty acids contribute to weight
gain in people who are predisposed to obesity (when people who are
predisposed to obesity consume long-chain saturated fatty acids,
these fatty acids are incorporated into adipose tissue rather than
being metabolized for the production of energy).
Excessive fructose-induced
triglycerides are implicated in obesity (due their storage as
adipose tissue).
Excessive Glucose-6-Phosphate
Dehydrogenase (G6PD) activity contributes to or exacerbates Obesity
(G6PD facilitates the storage of fats in adipose
tissue).
Excessive activity of lipoprotein
lipase in adipocytes contributes to obesity (lipoprotein lipase
catalyzes the breakdown of triglycerides from lipoprotein into their
constituent fatty acids and glycerol for uptake into
adipocytes).
People with a low ratio of Brown
Adipose Tissue (BAT) to White Adipose Tissue are more prone to
Obesity. Lowered Basal Metabolic Rate (BMR) can result in Obesity.
The Basal Metabolic Rate (BMR) of people afflicted with Obesity is
an average of 8% lower than that of non-obese
people.
Excessive levels of Cortisol
contribute to the development of Obesity. The in vitro effects of
cortisol and GH on basal and stimulated lipolysis in human adipose
tissue were studied using a tissue incubation technique. After
preincubation for 3 days in control medium containing insulin,
adipose tissue pieces were exposed to cortisol for 3 days. GH was
added to the cortisol-containing medium during the last 24 h (day
6). Adipocytes were then isolated, and lipolysis was studied in the
absence and presence of isoprenaline, noradrenaline, forskolin, and
N-6-monobutyryl-cAMP. Cortisol reduced the basal rate of lipolysis
(P < 0.01) and the sensitivity to isoprenaline compared to the
control values (P < 0.01). Addition of GH to the
cortisol-containing medium increased the basal rate of lipolysis (P
< 0.01) and the sensitivity to isoprenaline (P < 0.01) to the
control level and increased the maximum isoprenaline-induced
lipolytic activity (P < 0.01).Similar effects were obtained in
the presence of noradrenaline.Maximum forskolin-induced lipolytic
activity was reduced after exposure of the tissue to cortisol (P
< 0.05), whereas addition of GH antagonized this effect (P <
0.01). Induction of the maximum lipolytic activity with
N-6-monobutyryl-cAMP was not influenced by the preceding hormone
exposure. Addition of GH alone during the last 24 h of incubation
increased the basal rate of lipolysis (P < 0.05) and resulted in
a borderline significant increase in the maximum
isoprenaline-induced lipolytic activity (P = 0.055), suggesting that
GH induces lipolysis also in the absence of glucocorticoids.Cortisol
and GH have opposite effects on the basal lipolytic activity in
human adipose tissue in vitro as well as on the sensitivity to
catecholamines, GH being the lipolytic and cortisol the
antilipolytic agent. (Ottosson, M., et al. Effects of cortisol and
growth hormone on lipolysis in human adipose tissue. J Clin
Endocrinol Metab.85(2):799-803, 2000.)
THYROID ISSUES &
OBESITY
Obesity can occur as a result of the lowered
basal metabolic rate that occurs as a result of hypothyroidism
(underactive thyroid). Persons afflicted with obesity tend to
exhibit Triiodothyronine (T3) levels that are an average 30% lower
than those of non-obese subjects (which suggest that raising
triiodothyronine levels to normal ranges may facilitate weight loss
in the obese):
Thyroid hormones are
derivatives of the amino acid tyrosine bound covalently to iodine.
The two principal thyroid
hormones are:
thyroxine
(known affectionately as T4 or
L-3,5,3',5'tetraiodothyronine)
triiodotyronine
(T3 or L-3,5,3'-triiodothyronine).
As shown in the following
diagram, the thyroid hormones are basically two tyrosines linked
together with the critical addition of iodine at three or four
positions on the aromatic rings. The number and position of
iodinated molecules are generated that have little or no biological
activity; so called "reverse T3" (3,3',5'-T3) is such an example.
The number and position of the iodines is important. Several other
iodinated molecules are generated that have little or no biological
activity; so called "reverse T3" (3,3',5'-T3) is such an
example:

A large majority of the
thyroid hormone secreted from the thyroid gland is T4, but T3 is the
considerably more active hormone. Although some T3 is also secreted,
the bulk of the T3 is derived by deiodination of T4 in peripheral
tissues, especially liver and kidney. Deiodination of T4 also yields
reverse T3, a molecule with no known metabolic activity.
Thyroid hormones are poorly
soluble in water, and more than 99% of the T3 and T4 circulating in
blood is bound to carrier proteins. The principle carrier of thyroid
hormones is thyroxine-binding globulin, a glycoprotein synthesized
in the liver. Two other carriers of import are transthyrein and
albumin. Carrier proteins allow maintenance of a stable pool of
thyroid hormones from which the active, free hormones are released
for uptake by target cells.
Thyroid
Hormone Receptors and Mechanism of Action
Receptors for thyroid
hormones are intracellular DNA-binding proteins that function as
hormone-responsive transcription factors, very similar conceptually
to the receptors
for steroid hormones.
Despite being derived from an
amino acid, thyroid hormones are hydrophobic in character and appear
to enter cells and nuclei by diffusion through cell membranes. Once
inside the nucleus, the hormone binds its receptor, and the
hormone-receptor complex interacts with specific sequences of DNA in
the promoters of responsive genes. The effect of receptor binding to
DNA is to modulate gene expression, either by stimulating or
inhibiting transcription of specific genes.
For the purpose of
illustration, consider one mechanism by which thyroid hormones
increase the strength of contraction of the heart. Cardiac
contractility depends, in part, on the relative ratio of different
types of myosin proteins in cardiac muscle. Transcription of some
myosin genes is stimulated by thyroid hormones, while transcription
of others in inhibited. The net effect is to alter the ratio toward
increased contractility. For additional details on mechanism of
action and how these receptors interact with other transcription
factors, examine the section Thyroid
Hormone Receptors.
Physiologic
Effects of Thyroid Hormones
It is likely that all cells
in the body are targets for thyroid hormones. While not strictly
necessary for life, thyroid hormones have profound effects on many
"big time" physiologic processes, such as development, growth and
metabolism. Many of the effects of thyroid hormone have been
delineated by study of deficiency and excess states, as discussed
briefly below.
Metabolism: Thyroid hormones stimulate
diverse metabolic activities most tissues, leading to an increase in
basal metabolic rate. One consequence of this activity is to
increase body heat production, which seems to result, at least in
part, from increased oxygen consumption and rates of ATP hydrolysis.
By way of analogy, the action of thyroid hormones is akin to
blowing on a smouldering fire. A few examples of specific
metabolic effects of thyroid hormones include:
- Lipid
metabolism: Increased thyroid hormone levels stimulate fat
mobilization, leading to increased concentrations of fatty acids
in plasma. They also enhance oxidation of fatty acids in many
tissues. Finally, plasma concentrations of cholesterol and
triglycerides are inversely correlated with thyroid hormone levels
- one diagnostic indiction of hypothyroidism is increased blood
cholesterol concentration.
- Carbohydrate
metabolism: Thyroid hormones stimulate almost all aspects
of carbohydrate metabolism, including enhancement of
insulin-dependent entry of glucose into cells and increased
gluconeogenesis and glycogenolysis to generate free glucose.
Growth: Thyroid hormones are clearly
necessary for normal growth in children and young animals, as
evidenced by the growth-retardation observed in thyroid deficiency.
Not surprisingly, the growth-promoting effect of thyroid hormones is
intimately intertwined with that of growth
hormone, a clear indiction that complex physiologic processes
like growth depend upon multiple endocrine controls.
Development: A classical experiment in
endocrinology was the demonstration that tadpoles deprived of
thyroid hormone failed to undergo metamorphosis into frogs. Of
critical importance in mammals is the fact that normal levels of
thyroid hormone are essential to the development of the fetal and
neonatal brain.
Other
Effects: As mentioned above, there do
not seem to be organs and tissues that are not affected by thyroid
hormones. A few additional, well-documented effects of thyroid
hormones include:
1.
Cardiovascular system: Thyroid hormones
increases heart rate, cardiac contractility and cardiac output. They
also promote vasodilation, which leads to enhanced blood flow to
many organs.
2.
Central nervous system: Both decreased and
increased concentrations of thyroid hormones lead to alterations in
mental state. Too little thyroid hormone, and the individual tends
to feel mentally sluggish, while too much induces anxiety and
nervousness.
3.
Reproductive system: Normal reproductive
behavior and physiology is dependent on having essentially normal
levels of thyroid hormone. Hypothyroidism in particular is commonly
associated with infertility.
Thyroid
Disease States
Disease is associated with
both inadequate production and overproduction of thyroid hormones.
Both types of disease are relatively common afflictions of man and
animals.
Hypothyroidism is the result from any
condition that results in thyroid hormone deficiency. Two well-known
examples include:
- Iodine
deficiency: Iodide is absolutely necessary for production of
thyroid hormones; without adequate iodine intake, thyroid hormones
cannot be synthesized. Historically, this problem was seen
particularly in areas with iodine-deficient soils, and frank
iodine deficiency has been virtually eliminated by iodine
supplementation of salt.
- Primary
thyroid disease: Inflammatory diseases of the thyroid that destroy
parts of the gland are clearly an important cause of
hypothyroidism.
Common symptoms of
hypothyroidism arising after early childhood include lethargy,
fatigue, cold-intolerance, weakness, hair loss and reproductive
failure. If these signs are severe, the clinical condition is called
myxedema. In the case of iodide deficiency, the thyroid becomes
inordinantly large and is called a goiter. The most severe and
devastating form of hypothyroidism is seen in young children with
congenital thyroid deficiency. If that condition is not corrected by
supplemental therapy soon after birth, the child will suffer from
cretinism, a form of irreversible growth and mental retardation.
Most cases of hypothyroidism are readily treated by oral
administration of synthetic thyroid hormone. In times past,
consumption of desiccated animal thyroid gland was used for the same
purpose.
Elevated insulin levels increase
the risk of obesity. Insulin resistance is a very common underlying
cause of obesity (in the presence of insulin resistance excessive
serum glucose (blood sugar) is converted to adipose tissue (body
fat) rather than being utilized by the body's cells for the
endogenous production of energy).
Persons afflicted with Obesity
have blood levels of Leptin that are five times higher than those of
normal, healthy persons (although Leptin exerts anti-Obesity
effects, persons afflicted with Obesity are insensitive to its
effects).
Excessive secretion or production
of Neuropeptide Y can cause obesity (by stimulating excessive
appetite for carbohydrates and by stimulating excessive insulin
secretion, leading to insulin resistance).
Excessive production/release of
prolactin may contribute to obesity (as it increases the formation
of adipose tissue).
Wilson's thyroid syndrome patients
are prone to obesity and have extreme difficulty losing weight (due
to their low basal metabolic rate).
Trans-Fatty Acids increase the
size and quantity of adipose tissue (body fat) and therefore
increase the risk of obesity.
Lead has been implicated in
obesity. Epidemiological studies have found a direct correlation
between the incidence of obesity and the exposure of persons
afflicted with obesity to lead, especially during
childhood.
Excessive zinc has been associated
with obesity.
Slow (decreased) activity of the
Adrenergic Nervous System can be an underlying cause of Obesity due
to lowered Basal Metabolic Rate and fewer Nerve Impulses that
activate Adrenergic Receptors on Brown Adipose Tissue. Alpha-2
Adrenergic Receptors are located on Adipocytes (and are especially
prolific on Adipocytes in the lower half of the body. Did you know
that the lower half of the female body contains nine times the
number of Alpha-2 Adrenergic Receptors compared to Beta-1 Adrenergic
Receptors? Stimulation of Alpha-2 Adrenergic Receptors located on
adipocytes blocks the mobilization of triglycerides out of the
adipocyte (i.e. Alpha-2 adrenergic receptor agonists inhibit
lipolysis). In other words stimulation of alpha-2 adrenergic
receptors inhibits weight loss in persons afflicted with obesity.
Persons with a genetic predisposition to obesity have a diminished
number of and/or defective Beta-3 Adrenergic
Receptors.
Obesity can occur as a result of
Cushing's Syndrome.
Temporary obesity can occur as a
result of seasonal affective disorder
(SAD).
Alcohol (ethanol) intake even
while dieting, significantly reduces the body's ability to burn fat
and increases the body's tendency to store fat;when alcohol replaces
other foods in calorie equivalent quantities in the diets of healthy
young males, the rate at which their bodies burned fat decreased by
33%.
The drugs Clonidine, Histamine H1
Receptor Antagonists, Medroxyprogesterone (a Progestin),
Pharmaceutical Corticosteroids, can exacerbate
obesity.
Obesity can occur as a symptom of
male menopause. Sudden weight gain can occur as a result of the
PMS-H (Hyperhydration) form of Pre-Menstrual Syndrome
(PMS).
Obesity harmfully increases the
risk to health through cardiovascular disease, atherosclerosis,
hypertension (high blood pressure), ischemic heart disease,
pulmonary hypertension, stroke, thrombosis, varicose veins and
aggravates varicose veins, disorders of the gallbladder, greater
incidence of gallstones excretory system, kidney disease, cataracts,
suppresses the production of human growth hormone, toxicity to the
immune system (due to autoxidation), some forms of cancer (breast
cancer, cervical cancer, colon cancer (especially in males),
endometrial cancer, lung cancer, (non-hodgkin's) lymphomas, ovarian
cancer (in women), prostate cancer, uterus cancer, malignant
melanoma form of skin cancer), elevated serum cholesterol, diabetes
mellitus type 2, peroxidized fats than normal healthy people,
backache, gout, osteoarthritis, asthma, excessive bleeding during
menstruation, polycystic ovary syndrome (pcos), reduces anabolic
testosterone and growth hormone.
Obesity interferes with the body's
ability to manufacture vitamin D from the uv-b component of sunlight
(this causes an increased prevalence of vitamin D deficiency in
persons afflicted with obesity).
Acupuncture is not an effective
therapy for achieving weight loss in persons afflicted with obesity
(several scientific studies have indicated that Acupuncture is
effective against obesity however later studies have revealed flaws
in the original studies).
THESE SUBSTANCES FACILITATE WEIGHT
LOSS IN OBESITY PATIENTS
Caffeine (percutafeine gel form
applied topically) is prescribed in France to stimulate weight loss
in specific areas of the body (in persons afflicted with
obesity).
Capsaicin facilitates weight loss
in persons afflicted with obesity by increasing the body's basal
metabolic rate (BMR) and by stimulating lipolysis.
Dihydrocapsaicin facilitates
weight loss in persons afflicted with
obesity.
Ephedrine facilitates weight loss
in people afflicted with obesity (by stimulating thermogenesis,
increasing the body's basal metabolic rate (BMR) and by activating
beta-3 adrenergic receptors). Aspirin further potentiates the
ability of ephedrine to stimulate weight loss and thermogenesis -
aspirin suppresses modulators that normally (partially) inhibit
ephedrine's thermogenic effects. The dosage of aspirin used in
clinical trials that demonstrated its ability to potentiate the
weight loss caused by ephedrine was 325 mg of aspirin + 20 mg
ephedrine, three times per day (= 975 mg aspirin + 60 mg
ephedrine).
Ephedrine is even more effective
in the treatment of obesity when it is combined with caffeine -
caffeine further suppresses modulators that normally inhibit
ephedrine's thermogenic effects. The combination of Ephedrine +
Caffeine is regarded as the best anti-Obesity treatment but
considerations for safety are inconclusive. Ephedrine + Caffeine is
the only weight loss therapy that spares muscle during weight loss.
Ephedrine + caffeine causes 100% more fat loss and 72% less muscle
loss than the results obtained by dieting alone. The current
scientific consensus is that the maximum weight loss effects of
ephedrine are achieved when a combination of 20 mg ephedrine + 82 mg
aspirin + 200 mg caffeine is used three times per day. Willowbark
enhances the ability of ephedrine to facilitate (via thermogenesis)
weight loss in people afflicted with obesity (when consumed
concurrently with ephedrine or ephedra) (due to the salicin content
of willowbark). CAUTION: I do not recommend use of the CAE stack for
weight loss.
Nicotine helps to prevent obesity
(by increasing the body's basal metabolic rate) - nicorette (chewing
gum form of nicotine) is under investigation as a novel means of
preventing obesity: CAUTION:NICOTINE presents several toxic side
effects.
Synephrine increases the body's
Basal Metabolic Rate (BMR), stimulates thermogenesis and thereby
facilitates weight loss in persons afflicted with obesity (primarily
by stimulating adrenaline and norepinephrine release and by
activating various adrenergic receptors).
Yohimbine facilitates weight loss
(especially weight loss in areas of the body below the waist,
particularly the thighs) in persons afflicted with obesity (by
stimulating the process of thermogenesis and the process of
lipolysis via antagonism of Alpha-2 Adrenergic
Receptors).
5-Hydroxytryptophan 5-HTP (900 mg
per day) reduces appetite in people afflicted with Obesity. 5-HTP is
formulated in REM Caps & Appestat.
Alanine reduces body weight in
persons afflicted with obesity (by approximately
10%).
Arginine facilitates weight loss
in persons afflicted with obesity by stimulating the Pituitary to
release Human Growth Hormone.
Branched-Chain Amino Acids (BCAAs)
supplementation (combined with a low-calorie diet) facilitates
weight loss in persons afflicted with
obesity.
Carnitine (2,000-3,000 mg per day)
alleviates obesity. Carnitine allows the body to use the fats stored
in adipose tissue for energy production.
Cysteine facilitates the body's
use of adipose tissue as a source of
energy.
Glutamine reduces body weight in
persons afflicted with obesity (by approximately
10%).
Hydroxy Methylbutyrate (HMB) (3
grams per day combined with isotonic exercise) causes significant
weight loss in persons afflicted with obesity.
Lysine enhances arginine's role in
facilitating weight loss in persons afflicted with
obesity.
Tyrosine reduces adipose
tissues.
Beta 1,6 Glucan enhances weight
loss in persons afflicted with obesity.
Chitosan facilitates weight loss
in persons afflicted with obesity - it inhibits the further
digestion of dietary fats from the digestive tract by binding to
lipids (including fatty acids) and thereby facilitating their
excretion. Within the intestines, chitosan forms a gel that binds to
approximately 5 times its own weight of dietary fats - once the
dietary fats are bound to chitosan, they become unavailable for
further metabolism by the body and are eliminated via the feces.
Chitosan decreases the absorption of dietary fats by up to 26% in
the small intestine. For Chitosan to be maximally effective in the
inhibition of the absorption of dietary fats, it must be present in
high concentrations (i.e. Approximately 7.5% of the total
diet).
Chondroitin sulfate facilitates
weight loss in persons afflicted with obesity (by inhibiting the
activity of pancreatic lipases, reducing the absorption of dietary
fats in the small intestine and by decreasing the uptake of fats
into adipose tissue).
Glucomannans (3,000 mg per day)
cause significant weight loss in persons afflicted with
obesity.
Guar Gum facilitates weight loss
in persons afflicted with obesity.
Hemicelluloses enhance weight loss
in persons afflicted with obesity.
Psyllium facilitates weight loss
in obesity patients (by delaying the emptying of the stomach
psyllium seeds/husks suppress the appetite).
Xylitol enhances the process of
thermogenesis and may thereby facilitate weight loss in obesity
patients.
Exposure to sunlight facilitates
weight loss in persons afflicted with obesity (by stimulating the
thyroid gland and increasing the body's basal metabolic rate).
Caution: the detrimental effects of excess exposure to sunlight may
occur.
Supplemental pancreatic enzymes
can cause weight loss in persons afflicted with obesity (by causing
decreased food intake as a result of stimulating endogenous
substances that suppress the appetite). Supplemental pancreatic
enzymes are included in Premium Insurance Caps and Race Caps
Supreme.
Beta-3 Adrenergic Receptor
Agonists stimulate the production of brown adipose tissue (BAT) and
are currently in the early stages of testing on humans for the
prevention or alleviation of obesity. Beta 3 Adrenergic Receptor
Agonists have already been proven to stimulate the production of
brown adipose tissue in obese mice. The experimental Beta-3
Adrenergic Receptor Agonist code-named BRL 35135 was orally
administered to obese rats at the rate of 0.5 mg per kg - this
treatment resulted in a 45-fold increase in thermogenesis in brown
adipose tissue and a decrease in plasma insulin levels of 50%.
Humans receiving the experimental Beta-3 Agonist code-named BRL
26830A for 18 weeks experienced weight loss of an average 15 kg.
Adrenaline increases the rate of breakdown of adipose tissue (body
fat) into triglycerides (i.e. Via lipolysis) as an energy source
(and is therefore involved in facilitating weight loss in persons
afflicted with obesity) - this action of adrenaline is mediated via
activation of beta-3 adrenergic receptors.
Oleoyl Estrone (a synthetic, fatty
ester of Estrone) facilitates weight loss in persons afflicted with
obesity. Rats administered oleoyl estrone lost 25% of body weight in
2 weeks: weight loss occurred solely from adipose tissue loss and
not from muscle loss.
Insulin-like Growth Factor-1
(IGF-1) is under investigation as a potential therapeutic agent in
the treatment of obesity (due its ability to mobilize fatty acids
from adipose tissue for the endogenous production of
energy).
Supplemental 7-Keto DHEA
facilitates weight loss in persons afflicted with obesity (by
facilitating the process of
thermogenesis).
Cholecystokinin (CCK) helps to
prevent obesity (by suppressing appetite). Animals afflicted with
obesity are less sensitive to the appetite-suppressant effects of
CCK than non-obese animals.
Human growth hormone (hGH)
replacement therapy reduces visceral fat and subcutaneous fat in
persons afflicted with obesity (in persons with a clear-cut hGH
deficiency). Human growth hormone (hGH) also helps to prevent
obesity in elderly persons by inhibiting the formation of adipose
tissue.
TESTOSTERONE facilitates weight
loss in persons afflicted with obesity (primarily by stimulating
lipolysis and by inhibiting the activity of lipoprotein lipase in
adipocytes). Obesity (of the stomach and hips in women and of the
stomach in men) can occur as a result of insufficient endogenous
production of testosterone.
Optimal levels of THYROID HORMONES
prevent obesity. Caution: exogenous, supplemental thyroid hormones
should not be utilized for weight loss purposes unless there is a
clear deficiency of thyroid hormones is determined monitored by your
physician. Diiodotyrosine (T2) facilitates weight loss in persons
afflicted with obesity (due to its ability to increase Basal
Metabolic Rate). Thyroxine (T4) (Percutacrine Thyroxinique applied
topically) is used in France to stimulate weight loss in specific
areas of the body in persons afflicted with obesity and has been
reported to be highly effective. Tiratricol (a metabolite/analog of
Triiodothyronine) facilitates weight loss in persons afflicted with
obesity (due to its ability to mimic the ability of Triiodothyronine
(T3) to increase the body's Basal Metabolic Rate). Triiodothyroinine
(T3) facilitates weight loss in persons afflicted with obesity (by
increasing the body's basal metabolic
rate).
FORSKOLIN facilitates weight loss
in persons afflicted with obesity (it stimulates the production of
cyclic amp (camp) which in turn regulates the process of lipolysis).
Forskolin inhibits the endogenous synthesis of fatty acids in
adipocytes. Forskolin counteracts the decreased response by
adipocytes to adrenaline (which occurs as a result of the aging
process).
Gamma-Linolenic Acid (GLA)
facilitates weight loss in persons afflicted with obesity (this
occurs via the following process: GLA converts to DGLA, which
converts to Prostaglandin E1 which stimulates the activity of Adenyl
Cyclase resulting in increased levels of cyclic AMP (cAMP);
increased cAMP subsequently leads to increased
lipolysis.
Medium-Chain Triglycerides (MCTs)
help to prevent and treat obesity by stimulating the process of
thermogenesis (unlike many other dietary Fats, MCTs are
inefficiently stored within the body's Adipose Tissues, due to their
rapid conversion to Energy). MCTs are most effective for obesity
when used as a replacement for other types of dietary fats (rather
than being used in addition to other types of dietary fats such as
long-chain saturated fatty acids).
Prostaglandin E1 (PGE1) alleviates
obesity (this occurs from PGE1 stimulating the production of Brown
Adipose Tissue and from PGE1 stimulating Adenyl Cyclase resulting in
increased production of cyclic AMP (cAMP) - a compound that
stimulates lipolysis).
Superunsaturated Fatty Acids
facilitate weight loss from adipose tissue (due to their ability to
induce thermogenesis). Alpha-Linolenic Acid (LNA) facilitates weight
loss by increasing the body's basal metabolic rate, increasing
oxidation, functioning as an uncoupling agent and increasing Energy
production in the body. Docosahexaenoic Acid (DHA) facilitates
weight loss from Adipose Tissue (due to its ability to induce
thermogenesis via increased uncoupling protein 3
production/activity). Fish oils (6,000 mg per day) facilitate loss
of adipose tissue (bodyfat) in persons afflicted with obesity.
Menhaden oil helps to control obesity by facilitating the transport
of endogenous fatty acids into the mitochondria of cells for use in
the production of energy (it achieves this by decreasing the
sensitivity of Carnitine Palmitoyltransferase (CPT I form) to
inhibition by Malonyl Coenzyme A)
Flax seed oil is a valuable
adjunctive treatment for obesity.Flax seed oil helps the kidneys to
eliminate excess water and increases the body's basal metabolic
rate, oxidation rate and production of energy (due to the
alpha-linolenic acid (LNA) content of flax seed oil). In addition
the LNA content of flax seed oil functions as an uncoupling agent.
Calcium (1,000 mg per day)
facilitates weight loss in persons afflicted with
obesity.
Chromium facilitates weight loss
in persons afflicted with obesity (by improving the body's
utilization of Glucose - due to chromium polynicotinate being a
component of Glucose Tolerance Factor).
Iodine facilitates weight loss in
persons afflicted with obesity (where obesity is caused by
Hypothyroidism).
Magnesium facilitates weight loss
in persons afflicted with Obesity (due to its role in the production
of Adenosine Triphosphate (ATP)).
Manganese may alleviate
obesity.
Hydroxycitric Acid (-HCA)
facilitates weight loss in persons afflicted with obesity by
preventing the conversion of excess dietary carbohydrates to adipose
tissue (by inhibiting the ATP-Citrate Lyase enzyme).HCA is
formulated in Appestat Caps.
Metformin facilitates weight loss
in persons afflicted with Obesity (by increasing the body's
sensitivity to Insulin).
Orlistat is designed for the
treatment of obesity (by inhibiting pancreatic lipases, Orlistat
prevents the absorption of dietary fats as without pancreatic
lipases, fat molecules remain too large to be absorbed by the
intestines).
Pharmaceutical appetite
suppressants are often prescribed to suppress the appetite in
persons afflicted with obesity.
Sibutramine is used to facilitate
weight loss in persons afflicted with obesity (by suppressing the
appetite).
Preliminary research indicates the
Daidzein (found in soy proteins) facilitates weight loss (IN WOMEN
ONLY) - this means that Daidzein may be beneficial for women
afflicted with obesity.
Epigallo-Catechin-Gallate (EGCG)
(90 mg per day) facilitates weight loss in persons afflicted with
obesity.
Increasing dietary protein intake
to an amount that equals 25% of total calorie intake facilitates
weight loss and white adipose tissue reduction in persons afflicted
with obesity.
Persons afflicted with obesity are
often deficient in Coenzyme Q10 - CoQ10 supplementation accelerates
weight loss where CoQ10 deficiency has been established. (Race Caps
Supreme is an excellent source of Coenzyme
Q-10.)
Bromocriptine facilitates weight
loss in persons afflicted with obesity (the speculated mechanism for
additional weight loss with bromocriptine is via suppression of
appetite).
Choline supplementation helps to
prevent obesity (this occurs from choline facilitating the retention
of carnitine, a compound with known anti-obesity effects).
Vitamin B5 facilitates weight loss
in persons afflicted with obesity (by facilitating the processes of
thermogenesis, beta-oxidation and peristalsis).
Vitamin C facilitates weight loss
in people afflicted with obesity.
Vitamin D helps to prevent obesity
(by lowering the secretion of leptin).
Dumontiaceae facilitates weight
loss in persons afflicted with obesity.
Kelp alleviates obesity where
obesity is due to hypothyroidism (due to the Iodine in Kelp
increasing the body's Basal Metabolic
Rate).
Spirulina (8,400 mg per day)
facilitates weight loss in persons afflicted with
obesity.
Grapefruit (juice) facilitates
weight loss in persons afflicted with
obesity.
Banaba Leaf facilitates weight
loss in persons afflicted with obesity (probably due to the
Corosolic Acid content of Banaba Leaf).
Brindle Berry (rind) accelerates
weight loss in persons afflicted with obesity (due to the
Hydroxycitric Acid content of Brindle Berry preventing the
conversion of excessive dietary carbohydrates to adipose
tissue).
Chillis are of assistance to
persons afflicted with obesity (due to the Capsaicin content of
Chilli increasing the body's BMR by stimulating the thyroid and due
to the Capsaicin content of Chillis stimulating lipolysis).
Daikon helps to dissolve hard fat
deposits embedded in the body's tissues.
Dandelion facilitates weight loss
in persons afflicted with obesity.
Ginger facilitates weight loss in
people afflicted with obesity (due to the ability of Ginger to
increase the body's Basal Metabolic Rate (BMR) which results in
greater activation of Beta-3 Adrenergic Receptors on brown adipose
tissue resulting in greater
thermogenesis).
Green tea (and to a lesser extent,
black tea) facilitates weight loss in obesity by increasing the
process of thermogenesis (due to the tea polyphenols and
theophylline content of tea). Green tea reduces the absorption of
dietary fats (by approximately 40%) by blocking the production of
digestive enzymes that facilitate the absorption of dietary fats.
Green tea suppresses appetite.
Guggulipid facilitates weight loss
in persons afflicted with obesity (by stimulating the production of
thyroid hormones).
Gymnema sylvestre (a herb) helps
to prevent obesity by reducing the appetite (and craving) for
carbohydrates.
Korean ginseng is a useful weight
loss aid for the treatment of obesity (due to its ability to
stimulate the process of thermogenesis).
When used in conjunction with
engaging in exercise, maral root causes loss of body weight
(including loss of body weight in persons afflicted with obesity)
(due to the beta-ecdysterone content of maral
root).
Sida cordifolia facilitates weight
loss in persons afflicted with Obesity (due to the Ephedrine content
of Sida cordifolia).
Willowbark enhances the ability of
ephedrine to facilitate (via thermogenesis) weight loss in people
afflicted with obesity (when consumed concurrently with ephedrine or
ephedra) (due to the salicin content of
willowbark).
Yohimbe facilitates weight loss
(especially weight loss in areas of the body below the waist,
particularly the thighs) in persons afflicted with obesity (due to
the yohimbine content of yohimbe stimulating the process of
thermogenesis and the process of lipolysis via antagonism of alpha-2
adrenergic receptors).
Maitake Mushrooms enhance weight
loss in persons afflicted with obesity (due to the Beta 1,6 Glucan
content of Maitake).
Coconut Oil facilitates weight
loss in persons afflicted with obesity (due to the high content of
medium-chain saturated fatty acids in Coconut Oil).
Mustard seeds facilitate weight
loss in persons afflicted with obesity (by increasing the body's
basal metabolic rate (BMR).
Psyllium seeds/husks facilitate
weight loss in obesity patients (by delaying the emptying of the
stomach psyllium seeds/husks suppress the
appetite).
Garlic is useful in the treatment
of obesity (it increases blood levels of norepinephrine which leads
to enhanced thermogenesis in brown adipose tissue).
All forms of exercise facilitate
weight loss in persons afflicted with obesity. Clinical studies have
shown that the exercise undertaken first thing in the morning prior
to breakfast is more effective for weight loss than an equivalent
amount of exercise undertaken at other times of the day. Aerobic
exercise facilitates weight loss (especially bodyfat loss) in
persons afflicted with obesity. Ten minutes of running results in
the burning of approximately 150 calories (depending on body size).
Endurance exercise facilitates weight loss (especially bodyfat loss)
in persons afflicted with obesity. Isotonic exercise (i.e. Weight
lifting) facilitates loss of bodyfat (especially in persons
afflicted with obesity) - this loss of bodyfat occurs primarily as a
result of the increased basal metabolic rate that occurs as a result
of isotonic exercise).

ADDENDUM Question:
What short-term
protocol is recommended for losing body fat
weight?
For reduction of your appetite
cravings take the following for up to 3-weeks then take a week off,
before repeating another 3-week session:
Weight loss and reduced appetite
occur when an athlete consistently follows the following
guidelines:
(1) Reduce normal carbohydrate
intake by 50%.
(2) Increase raw food vegetable
and fruit intake by 25%.
(3) Drink 8-10 glasses of water
per day.
(4) Eat no food after 7:00
PM.
(5) Reduce animal and dairy
byproducts to once per week.
(6) Exercise activity is conducted
at or below 75% VO2 Max Heart Rate.
(7) Take each of the Appestat
Caps product or ingredients:
L-Carnitine Tartrate250-500
mg
5-Hydroxy-Tryptophan<100-200
mg
Garcina Cambogia(Citri Max)200-300
mg
Chromium Polynicotinate
(Chromemate)100 Mg
Zinc (Opti-Zinc) 15
Mg
Kelp 40-225
mcg
Rationale:
L-Carnitine Tartrate is a fatty
acid carrier in mitochondria.
5-HydroxyTryptophan depresses of
brain receptor sugar-cravings.
Garcina Cambogia (Citrimax)
suppresses appetite.
Chromium Polynicotinate is a
carbohydrate metabolism-balancing substrate.
Zinc releases natural leptin from
body fat cells (leptin suppresses appetite).
Kelp enhances efficient thyroid
metabolic activity.
Directions: take 2 units of the
above 60 minutes prior to eating with 8 ounces distilled water or
100% pure fruit juice (apple, prune, orange, cranberry, or tomato)
note: do not use fruit juice that contains fructose or high fructose
corn syrup in the ingredients list.
The Appestat
Caps protocol is designed for short-term weight reduction in the
off-season not to exceed 2 periods of 21 days each nor more than 15
pounds weight loss.Athletes are advised to consult with their
physician before attempting a weight loss program and if on either
medications or if health concerns are contraindicated to a weight
loss supplement protocol. Lifestyle habits form the basis for weight
management and healthy natural control of Body Mass Index (BMI);
unless the regular dietary habits support weight mass control, fat
weight gain will result from caloric excess. Not one temporary diet
actually works, rather healthy daily dietary choice does work
favorably to control healthy muscle mass to fat weight
ratio.
For
additional information on weight management: At the end of
January 2001, AFPA President, Dr. Mark Occhipinti, Ph.D. and I
co-authored: Position Paper on Weight Management for the American
Fitness Professionals & Associates. This paper emphatically
encourages "Lifestyle" dietary adaptations with the adage, "Diets
Don't Work!" At any given time 45% of all American women and 25%
of all American men are dieting. A number of studies have shown that
after 90 days of weight loss from a caloric-restriction protocol,
90% of the dieters have regained the weight lost back plus more.
Within 5 years time [post-diet], all but 10% of the dieters have
gained it all back, including an additional fat weight above their
pre-diet level. If
interested, this referenced position paper is located on the AFPA
site:http://www.afpafitness.com/articles/AFPAPosWtMg.htm
How fat is too
fat?
A Body Mass Index (BMI) of 20-25 is regarded as
a healthy body weight in ratio to stature. To figure your BMI,
divide your weight in kilograms (1 lb = 0.45 kg) by height in meters
squared (1 inch = 0.0254 meters).

To determine if you are overweight, a measure
of male or female androids is called the Gynoid Obesity Ratio (GOF) for
significant health risk is:
(A) Males
>0.95
(B) Females
>0.80
TO DETERMINE GOR
FOR SIGNIFICANT HEALTH RISK:
(1) Measure waist circumference at navel
relaxed, not pulling in stomach.
(2) Measure girth
of buttocks/hips where girth is largest.
(3) Divide waist measure by hip
measure.
Examples: Waist (30") ÷ Hips (34")
= GOR of 0.88 or less than
<0.95.
Waist (36")
÷ Hips (34")
= GOR of 1.05 or greater
than
>0.95.
Percent Body Fat is a 3rd but less accurate
measure of excess body fat weight.As men and women age, their body
fat tends to increase gradually, silently, weekly, or seasonally.
With decrease in metabolic rate as anabolic growth rate ceases and
no decrease in food intake or exercise caloric expenditure, an
excess of ONLY 218 CALORIES(1 extra Bagel) will add 1 ounce FAT to
body adipose structures.

FACING THE PROBLEM OF UNWANTED WEIGHT
GAIN
If overeating were the major cause of obesity,
then cutting back on the amount of food intake or making different
food choices would dramatically solve or eliminate the problem, but
it does not always resolve fat weight gain. Brouchard (N ENGL J
MED;322:1477,1990.) studied 12 pairs of monozygotic twins for 100
days, overfeeding by 1000 kcal per day for 6 days per week to assess
the role of inherited characteristics on body fat storage from
overfeeding. This study showed that surplus energy intake did not
produce similar responses in the outcome variables among twin pairs.
Other than overeating, resting metabolic rate, dietary-induced
thermogenesis (Example: cayenne pepper), spontaneous
movement-fidgeting, basal body temperature, Levels of ATP,
Lipoprotein Lipase, Total Enzymes, metabolically active brown
adipose tissue, and muscle fiber type
makeup/distribution.
Genetics and hormonal factors causing obesity
are less than once formerly thought.Genetic factors contribute 25%
to percent body fat and fat mass, while cultural habits are blamed
for 30%, leaving 45% as nontransmissable factors. (Bouchard, C.,et
al., Int J OBES,12:205,1988.)
STRESS and SEDENTARY LIFESTYLE combine to
contribute most to the genetic susceptible individual weight
gain.
Research has identified a model operant in
human adipose tissue gain. A hormone-like protein, Leptin, has been
identified for activating the satiety response to stop eating. When
Leptin is released from fat tissue cell sites into the bloodstream,
it is carried to the ventromedial nucleus of the hypothalamus, the
control center for appetite satiety or hunger. This mechanism
derives the physiological "Setpoint" for bodyfat. The size of each
adipocyte, established before adulthood, may have some hormonal hold
on the amount of leptin available to quench the appetite center.
Endurance exercise will not reduce the size of the adopocytes, but
may reduce the number or congestive storage of adipose
tissue.
WHAT IS A GOOD DIET AND WHAT IS NOT?
Starvation is NOT a good practice nor
efficient for permanent weight loss/control.When calories are
dramatically reduced the resting metabolic response may decrease by
as much as -45%! I recommend no less than 1000 calories per day for
weight-loss. The 3 week cycle with a 1 week break, then return to
the cycle of 21 X 1000 calorie intake per day may be a good way to
lose 4-6 pounds every cyclic period.
WEIGHT LOSS WITHOUT COMMITMENT AND TIME DO NOT
OCCUR
Endurance exercise enhances mobilization and
utilization of body lipid stores and facilitates protein retention
in skeletal muscles retarding protein breakdown. During a 21-24 day
time period the following observed results occurred during a 1000
kcal per day caloric intake while exercising 2.5 hours per
day.

Exercise has an appetite-suppression role in
endurance athletes, but only when exercise demands are increased
above the present adaptive levels.Off-Season is when these select
athletes, who maintain minimum fitness, gain unwanted adipose tissue
weight.For health reasons it is wise to apply the above measures of
overweight excess once every quarter. Gains in the mid-section
(waist) are regarded as dangerous, however minute, and should be
monitored often.
Fat content in food is 97% deposited,
metabolizing only 3% of its hefty 9 calories per gram, while
Carbohydrates, simple or complex, are 77% deposited to muscle
glycogen stores, or if in excess of the needs for muscle glycogen
are deposited in adipose tissue sites.
Twenty-seven percent (27%) of the dietary
"Carbs" are required to metabolize themselves into the system via
the bloodstream and liver, but add only 4 calories per gram upon
gaining entry.It is, however, the excess dietary sugar, all fat, and
some of the complex carbohydrates that contribute to approximately
95% of all stored excess fat.
Advantages males have over female athletes when
it comes to weight loss is found in the different ways fat is
distributed by gender. Fat stored in upper body areas (stomach etc.)
is more responsive to neurohumoral stimulation. Waist and upper body
fat stores are preferentially mobilized during exercise far more
than the adipose stores below the waist.
COMMENT: I do
not advise long term weight loss unless morbid obesity and health
are the concerns of you and your family Medical doctor. Of those
observed on caloric restriction of 21 days on, 7 days off, success
rate is remarkable. As a precaution, weight control or weight loss
protocols should only be employed in the off season, since one of
the side effects to even mild weight reduction is
performance.
