Metabolife
...The catch is that the stimulants it contains can be dangerous:
the Food and Drug Administration has warned that products like
Metabolife can cause "cardiac arrhythmia and death". Several states
have moved to ban or restrict their use, and a few users have filed
lawsuits claiming injury.
Metabolife is just one of several popular supplements-others include
Therma Pro, Diet Pep and Diet Fuel-that combine caffeine with the
stimulant ephedra. Derived from mahuang, ephedra constricts the blood
vessels while speeding the heart and the nervous system. It also
helps supress appetite. What worries some experts is that it's
chemically identical to ephedrine, a synthetic compound regulated
for safety. Asthmatics take ephedrine to shrink swollen tissue in
their airways. Until the 1980s, it was also used in over-the-counter
cold and allergy pills, as a nasal decongestant. But when states
started restricting sales, manufacturers switched to a gentler chemical
called pseudoephedrine. "Ephedrine had too much potential for abuse,"
says Dr. Darrell Hulisz of the University Hospitals of Cleveland.
"It was used as cheap, legal speed."
The scientific record on Metabolife is still sketchy. In one small
experiment, researchers and Vanderbilt University clocked the
metabolic rates of 17 patients - once while they were taking the
supplement and once while they were taking a placebo - and found that
the rates picked up slightly on Metabolife. In another small study,
researchers at Columbia University and New York's St. Luke's Hospital
found that volunteers who took Metabolife for eight weeks lost more
weight then those taking placebo. But the study was neither large
nor long enough to prove the treatment effective, and it raised
questions about safety. The patients on Metabolife were more likely
to experience jitteriness, insomnia and heart palpitations, as well
as increased blood pressure. "In my mind, you treat obesity to lower
blood pressure", says Dr. Steven Heymsfield, an obesity specialist
who helped conduct the study (and who serves as a trustee for Slim-
Fast)."So anything that raises it is at least an orange flag."
Other orange flags include "adverse events" reported voluntarily
to the FDA. Those reports don't establish cause and effect, but
they document dozens of seizures, strokes and heart attacks-and
at least nine deaths-among ephedra users. (End)
States Make Serious Health Warning Mandatory!
Laws in some States are already beginning to make mandatory the requirement of serious health
warnings posting on all Metabolife products, such as this one in Texas:
Warning:"This product has ephedrine group alkaloids in the form
of herbal extracts and may cause serious adverse health effects".
Equal, If Not More Effective, Alternative Puts Safety First!
As existing thermogenics such as ma huang come under scrutiny from the
Food and Drug Adminstration and from State Regulators - and are in danger
of being removed from the marketplace, the need has arisen for a safe natural
and effective weightloss/fitness solution. Well, look no further that solution is
already here.
