Ephedra Substitutes
Ephedra-free & Thin as
Ever
Federal officials
announced on December 30, 2003 plans to ban dietary supplements containing
ephedra (also known as ma-huang) because of continued health concerns
about the product, and warned consumers not to take products containing the
herbal stimulant.
“The time to stop using
these products is now,” Health and Human Services Secretary Tommy Thompson told
reporters.
Some twelve to seventeen
million Americans use ephedra annually. The plain facts are that it has been
shown to be a valuable traditional herbal medicine, but that it can be dangerous
when it is abused. If you’re one of the vast majority of Americans who’ve been
using ephedra safely for weight loss, then you’re probably going to be seeking
ephedra alternatives as the herb becomes more and more difficult to obtain.
Unfortunately, some of the
users were, indeed, abusing the supplement. It is these relatively rare
instances of abuse and the dosages provided to consumers by a few overzealous,
irresponsible members of the nutritional product industry that contributed to
the proposed ban.
In the interests of a free
market and because our readers tend to be more sophisticated, we would have
preferred tougher labeling rather than to ban it completely. We must be alert
to be sure that the government doesn’t further encroach on our health freedoms.
The New Science of Weight
Loss
Fortunately, for
Healthy Living readers, we’ve been reporting for some time now on the new
generation of ephedra-free substitutes, trying to keep you ahead of the cure.
These products, when designed properly, show us that the future of fat loss for
dieters should not focus on reducing appetite alone. Rather, it should focus on
enhancing lipolysis (e.g., fat burning) and thermogenesis (e.g., the heightened
burning of calories), as well as overcoming the regulatory mechanisms designed
to prevent rapid and substantial fat loss. All of this might be said to
heighten one’s the metabolic rate.
Increasing the metabolic rate is beneficial in weight loss, since the metabolism
becomes sluggish in overweight and obese subjects placed on low calorie diets;
by increasing the metabolic rate, weight loss is improved. Since the breakdown
of stored fat is also increased, more of the weight loss comes from fat, and
body protein from lean tissues is spared, thus helping prevent the loss of lean
body mass that also often occurs during dieting.
This is what ephedra does
so well. But it is not for everyone, and if you’re one of the millions of
Americans now seeking non-ephedrine based supplements, one of the nation’s
leading natural remedy companies, Metabolic Response Modifiers (MRM), has
developed
Meta-Burn™ XTP.
It combines three of the
most important upcoming ephedra alternatives—green tea, octopamine
and Coleus forskholii—plus complexes for fine tuning thyroid
metabolism and enhancing metabolism.
This non-ephedrine
formulas can complement other nutritional weight-management formulas detailed in
Healthy Living. It provides similar benefits to ephedra-based
supplements but without the jitters or other risks.
Meta-Burn XTP
combines the synergistic powers of octopamine, green tea extract,
and Coleus forskholii at therapeutic dosages to provide a powerful
fat and calorie burning experience without the shakes and jitters associated
with ephedrine-based products. (In addition,
Meta-Burn XTP addresses sluggish thyroid function to further aid weight
loss, especially among mature dieters—to be covered in an upcoming report).
Safe Ephedra Alternative
“Weight loss products
containing synephrine and octopamine are apt to be the next wave in natural
weight loss products,” note Drs. Adriane Fugh-Berman and Tieraona Low Dog. Drs.
Fugh-Berman and Low Dog report participants in a recent six-week long, double
blind, randomized, placebo-controlled study with a product containing synephrine
and octopamine (as well as caffeine and St. John’s wort) “lost a significant
amount of weight” (1.4 kg) compared to the placebo group. The participants lost
2.9 percent of their body fat; there was no significant change in the placebo
group. “No significant changes were seen in any group in the profile of mood
states questionnaire, blood lipids, blood pressure, heart rate, EKG, serum
chemistries, or urinalysis. Basal metabolic rate increased significantly in the
treated group and decreased significantly in the placebo group; there was no
change in the control group. No side effects were reported.”
“Octopamine,” they say,
“appears to be more potent then synephrine.”
Octopamine, like ephedra,
is a natural beta-3 adrenergic receptor agonist; it is found in minute amounts
in various citrus and must be concentrated in order to exert its effects. In
classical tests, these citrus alkaloids show properties similar to ephedrine,
with activation of ß-receptors.[i],
[ii]
More recently, studies have shown that octopamine appears particularly
effective in stimulating fat burning (lipolysis), a postulated β3-receptor
effect.[iii],
[iv],
[v]
We reported in a recent
article that weight-loss scientists say beta-3 adrenergics are important to
weight loss, although such recognition did not come until the 1990s when beta-3
adrenergic receptors were isolated in both human white and brown adipose
tissues. Studies from The Sarah W. Stedman Center for Nutritional Studies, Duke
University Medical Center, Durham, North Carolina, show us that experimental
obesity can be prevented with the enhanced expression of beta-3 adrenergic
receptors, especially in brown adipose tissues.[vi]
In fact, it is has been shown that that beta-3 agonist activity could account
for at least forty percent of the thermogenesis induced by some weight loss
drugs.
Octopamine is thought to
be the first selective beta-3 agonist to be isolated and made available as a
nutritional supplement; it has been shown in experimental studies to possess
strong lipolytic activity in fat cells. In contrast to some ephedrine-based
supplements, a small clinical trial with twelve otherwise healthy but overweight
males, found that energy expenditure and fat burning rates increased without any
adverse effects on heart rate or blood pressure.
According to published research, “The efficacy and safety of octopamine and
related citrus is further confirmed in studies in lean and obese volunteers who,
while showing excellent thermogenic responses, failed to reveal any evidence of
increased heart rate, blood pressure or central nervous system stimulation.[vii],
[viii]
A clinical study reported also demonstrated excellent effects on weight loss
with a total absence of side effects.”[ix]
Comments
an expert, “Thus though the citrus alkaloids appear to be at least as
thermogenic as the ephedrine alkaloids, they are clearly gentler than the latter
and do not cause the minor side effects associated with use of ma-huang
(nervousness, agitation, palpitations, increases in blood pressure). The better
tolerance of the citrus alkaloids is thought to be because they do not pass so
readily into the brain, and may target fat cells rather more specifically.
But
there’s more to this formula, so hold on….
The MRM formula
contains green tea. Among ten healthy men, use of green tea extract resulted in
a “significant increase” in both energy expenditure and lipolysis.[x]
Dr. Abdul Dulloo
led the research into weight loss, which was conducted at the University of
Geneva. The Dulloo team studied the effects of green tea on ten healthy young
men (average age: 25) who ranged in body type from “lean” to “mildly
overweight.” The study’s participants were put on a “typical Western diet.”
For six weeks, the men took two capsules consisting of either green tea extract
plus 50 milligrams of caffeine; 50 milligrams of caffeine alone; or a placebo
with each meal.
Three times
during the study, researchers measured the men’s energy expenditure (EE, i.e.,
the number of calories used in a 24-hour period) in a respiratory chamber. They
also gauged the men’s respiration quotient (RQ, i.e., a measurement of how well
the body utilizes carbohydrates, proteins and fats. A lower RQ means that more
fats are being metabolized by the body for energy.)
Results showed
that those men taking the green tea extract experienced “a significant increase
in 24-h EE” and “a significant decrease in 24-h RQ” over those taking only
caffeine or the placebo. Men taking the green tea extract also used more fat
calories than those using the placebo.
The key
ingredient in green tea, scientists believe, are catechin polyphenols that
appear to alter the body’s use of norepinephrine, a chemical transmitter in the
nervous system, to increase the rate of calorie burning. “Green tea has
thermogenic properties and promotes fat oxidation beyond that explained by its
caffeine content per se,” say the scientists. “The green tea extract may play a
role in the control of body composition via sympathetic activation of
thermogenesis, fat oxidation, or both.”
As for safety,
use of green tea extract was “not accompanied by an increase in heart rate. This
leaves open the possibility of using green tea as an alternative to
stimulant-based diet drugs, which may cause adverse effects on obese individuals
and patients with hypertension and other cardiovascular conditions.”
Coleus
forskholii is able to start an important weight-loss cascade in the human
body, according to scientific studies.[xi],
[xii],
[xiii]
Forskolin is one
of several herbs and nutrients in the formula that is known to stimulate the
thyroid (specifically stimulating the production of T3). In a preliminary
open-field study, six overweight women were given 250 mg of forskolin extract
twice daily for eight weeks. Participants were asked to maintain their normal
diet and physical activity levels. To ensure maintenance of physical activity
levels, each participant answered multiple questionnaires throughout the study
period. The results indicated that the subjects lost an average of 10 pounds and
that the weight loss was progressive. That means that as the study proceeded,
weight loss continues in a linear fashion. The researchers said 80 percent of
the weight lost was fat weight. This aspect of weight loss must be
considered impressive. There were no noticeable changes in heart rate and
blood pressure.
EnergX, also in the formula, includes proven weight-loss
stimulants USP caffeine, guarana and theobromine, which are
rich in caffeine and methylxanthines and have a clear-cut thermogenic effect on
the body (although persons with high blood pressure or heart disease should not
exceed the recommended dosage).
Meanwhile, EnergX is a unique blend of
methylxanthines that help increase energy levels and supercharge your workouts.
XX (Xanthine Xcellerator) is a blend of bioflavonoids that has
been shown to also help mobilize lipids and lipid-metabolizing enzymes, as well
as optimize the body’s potential to increase
thermogenesis (increased calorie expenditure) without massive amounts of
caffeine. TyroBurn, a blend of L-tyrosine and bovine thyroid
extract, is specially designed to support optimal thyroid health especially
during times of strict caloric intake and exercise.
So alternatives to ephedra are readily available and
might even be better.
Meta-Burn XTP is perhaps the only total ephedrine-free fat burner
available today. Not only does it support fat burning (lipolysis) but also
supports healthy thyroid function to ensure your metabolic rate is at “full
speed” ALL DAY LONG!
