Dieters, beware

Supplements for weight loss are heavy on claims and light on scientific proof

 

  If there existed a safe, effective and rigorously
tested weight-loss pill that could help slim you down
without dangerous side effects, you’d be best off hearing
about it from your doctor. But for now, most weight-loss
[5] supplements are not evaluated for safety by the U.S.
Food and Drug Administration (FDA) and their too-goodto-
be-true promises come from marketers, whose claims
are facing scrutiny by the Federal Trade Commission.
  Diet-supplement claims were also at the center of
[10] a recent Senate hearing, where law-makers questioned
Dr. Mehmet Oz for having called some diet pills a
“miracle” and “magic weight-loss cure” despite a lack of
validated scientific evidence. And while prescription
weight-loss drugs like Belviq and Qsymia are regulated
[15] by the FDA, supplements are not. A bill introduced in
2013 requiring companies to register their products with
the FDA and improve labeling to include safety risks
and efficacy is now before a Senate committee. In the
meantime, here is what science says – or doesn’t say –
[20] about what’s out there.
  The universe of diet supplements

 

1. FAT BURNERS

( gamma linoleic acid, DNP)

AÇAI BERRY

 

Claim: They will “melt away” fat and help build muscle.

Science: Not much. There’s insufficient evidence that they can contribute to weight loss.

Risks: Some are banned by the FDA (though they remain available online) over risks of organ failure.

 

2. APPETITE SUPPRESSANTS

( hoodia, beta glucan)

WHEY

 

Claim: The pills and powders can make you feel full, causing you to eat less.

Science: There are few human studies confirming their effectiveness.

Risks: Since they haven’t been well studied, side effects are wholly unknown.

 

3.FAT BLOCKERS

(chitosan)

GUAR GUM, HYDROXYCITRATE

 

Claim: You won’t absorb as much dietary fat from your food.

Science: There isn’t strong evidence that these work without a low-calorie diet.

Risks: Some cause diarrhea and inhibit vitamin absorption, while others, made from shellfish, may trigger allergic reactions.

 

4.METABOLISM BOOSTERS

(leptin)

BITTER ORANGE, GREEN COFFEE

 

Claim: They help you burn more fat and calories.

Science: Stimulants may help cells use more energy, but they can come with serious adverse effects.

Risks: Some stimulants speed heart rate and blood pressure, and heart attacks have been reported.

It’s stated in the text:

 

( ) Some prohibited fat burners supplements can be bought through the Internet.

( ) If you are allergic to such foods as crabs and oysters, you should avoid products composed of chitosan.

( ) The fact that metabolism boosters might cause heartrelated problems is said to be a myth.

( ) Side effects of whey protein on dieters have not yet been scientifically confirmed.
