Is Shrimp Good For Weight Loss - No Good Evidence Weight Loss Supplements Work
Hundreds of weight loss supplements, such as green tea extract, cheitão, guar gum and conjugate linoleic acid are being addicted to aggressive marketing professionals. Estimated 34% of Americans who want to lose weight have tried one, according to the researchers.
"Temptation is great because someone has a megaphone, but you do not need an endorsement of celebrity and / or spiral headlines to tell you how to lose weight. The medical establishment will speak aloud and clearly when there is something to say, "The co-author of the study Dr. Srividya Kidambi, associate professor and head of endocrinology and molecular medicine at the Wisconsin Medical College.
To find out if 14 weight loss supplements and / or alternative therapies such as acupuncture do what they say, the researchers identified 315 randomized assays controlled, which are considered the gold standard in clinical research. Of these, 52 studies were considered unlikely to be biased. Only 16 studies showed weight differences among participants who receive treatment and those on the placebo arm.
Weight loss in these studies varied widely, less than 1 pound to just under 11 pounds. Weight loss was not seen consistently for any weight loss treatment, and many had conflicting results, with some studies showing weight loss and others showing such an effect.
The studies included in the review analyzed the chitosan, a sugar complex formed from the hard shells of seafood; Effected or caffeine; Green tea; guar gum; The extract of tropical fruits Garcinia Cambogia; Chocolate / Cocoa; Conjugated linoleic acid, a natural substance produced in the intestine by digestion of fats; white white beans (Phaseolus vulgaris); and calcium more vitamin D, among others. Alternative therapies of weight loss evaluated in studies included acupuncture, performance, hypnosis and meditation.
"The Dietary Supplement Industry is a Wild West of Herbs and Balcon Pills that have many claims and little of no evidence by supporting these claims," said the co-author of the study Dr. Scott Kahan, director of the National Center for Weight and well-being in Washington, DC "We all want a magic pill, but dietary supplements are not the magic pills that are marketed to be."
There are things that are proven to help you lose weight and keep you off, Kahan said.
The support of a dietetics, nutritional education and, in some cases, medication or weight loss surgery, can help weight loss, "he said.
The authors of the study issued a statement requesting regulatory supplements and more high quality studies to evaluate the risks and benefits of weight loss supplements. The study appears in the June 23 issue of obesity. His work comes on the heels of another study that found mainly weight loss supplements ineffective. This research was presented virtually last month at the European Congress on Obesity and published in the International Journal of Obesity.In the United States, supplements are not regulated in the same way that pharmaceuticals are, therefore, there is no way to know if you are actually getting what you are paying, said Kidambi.
Most weight loss supplements will cause no damage, but many false promises, she said. "If supplements take the diet site, regular exercises and behavioral changes, they will hurt you in the long run," she added.
Some online sold supplements can be attached to ingredients that are harmful and banned in the United States, watched Kidambi.
Weight loss supplements can also be expensive, she said.
It is buying buyer when it comes to weight loss supplements, agreed Dr. Louis Aronne, Founder and Director of the Comprehensive Hospital Weight Control Program New York-Presbyterian / Weill Cornell Medical Center in New York.
"There is very little research demonstrating that the supplements currently available produce significant weight loss," Aronne said, which was not involved in the new study.
Andrea Wong is a senior vice president of scientific and regulatory issues at the Responsible Nutrition Council, a Washington Based Group, D.C., representing the supplement industry.Wong, who has no ties for the survey, pointed out that the new study did not include all dietary supplements on the market today, some of which can help in weight loss efforts.
"Consumers should be cautious with products that promise to facilitate weight loss and always talk to a health professional for counseling on the programs of use of responsible supplements and weight management programs," she said.
