Effective Diet Supplements Help Reduce Weight?

Kapanlagi.com - "Burn fat while you sleep." "Reduce 10 Pounds in 10 days." We all know that the ad was too good to be true, but Americans still spend billions of dollars each year for the pill that is not regulated and poisons that promise weight loss.
While we may want to believe it is exaggerated, is there any scientific evidence to support it? According to findings from an analysis of the recently published, the answer is the pills are not qualified.
Two British researchers from the University of Exeter and Plymouth to review studies that evaluate weight loss among people who consume supplements found dozens of never preparing for weight control. They concluded that there was "little convincing evidence that there are specific ingredients of dietary supplements which can effectively lose weight."
Assistant author Max H. Pittler, MD, will not go that far to say that people are just wasting their money when they buy medicines / dietary supplements are not regulated, but he tells WebMD 'not much concrete evidence to show they can be effective. "
Effective
About 12 dietary supplements are reviewed, only two - ephedra and chromium picolinate - which proved more effective than placebo.
According Pittler, rigid review of the most useful shows ephedra weight loss associated with short-term. But it is also known to supplement accelerate heartbeat and inhibit blood vessel, thereby palpitations are common among the participants for the study of ephedra.
The beginning of this year, the FDA issued a rule prohibiting the sale of dietary supplements containing ephedra because it resulted in the risk of illness / injury that made no sense.
Rules, which contain ephedra to be removed from unregulated products sold in the U.S., will be effective later this month. This is the first time the FDA banned diet suplemet.
Others showed that supplements are effective for reducing body weight is metallic mineral chromium picolinate, which praised the hormone insulin can increase activity and reduce body fat. But the researchers concluded that the effects of weight loss of supplements it.
A review was published on the topic April American Journal of Clinical Nutrition.
Other supplements found to have only little or no effect for weight loss include:
• Chitosan - A material from the sea found in the framework of shrimp, crabs, and other Shellfish. Supplements that are used in products that promise to maintain fat diet so as not absorbed by the body. But the researchers concluded that "the available evidence in the literature shows that there is considerable doubt that chitosan is effective for weight loss."
Garcinia cambogia • - One of the main ingredient in one weight loss supplement best-selling, Hydroxycut. Researchers concluded that "evidence of G. cambogia is can not be forced."
• Pyruvate - a body formed during the decomposition of carbohydrates, was praised as a metabolism booster and stopping your appetite, but Pittler and Ernst reported that "the case of pyruvate as an aid to change the composition of the body and lose weight is weak."
Warning for buyers
Insufficient clinical evidence for other supplements that are sold to help you lose weight, including from green plants such as yerba and yohimbe and psyllium fiber, but the researchers concluded that "none of the reviewed dietary supplements can be recommended for use over-the-counter. "
Weight loss specialist Madelyn Fernstrom, PhD, says not surprised that the evidence does not support advertising dietary supplements for fast and easy weight loss. Fernstrom is director of the weight management center at the University of Pittsburgh's media center.
"There is no magic bullet," he tells WebMD. "If you're trying to reduce your weight with a pharmaceutical agents, immediate prescription drug search."
He added, is important for people to understand that a supplement is not always safe because it was not regulated. He cited products now being sold as "ephedra free," which may be as dangerous as it contains ephedra.
"There has been some supplements out there that is as dangerous to take over the place ephedra, and referred to as 'bitter orange'," she said. "People should be careful. Just because it is a food supplement, it does not mean it is safe." (Msn / Irene)
