This is the conclusion reached by specialists from the International Congress of Obesity, held in Stockholm last week. Find out what supplements that have tested and proved to be a lie.
Experts have analyzed the most popular weight loss supplements that exist in the market and found no evidence showing their effectiveness in weight loss. Therefore, if you put all your hopes in the hands of a weight loss supplement, do not make great illusion, because experts say they have only a placebo effect.
“There are a lot of supplements on the market that claim to help you lose, betting on various mechanisms. Unlike drugs for weight loss, they do not need studies to certify their efficiency before they entered the market in the world” , warns German doctor Ellrott Thomas, manager of the Institute for Nutrition and Psychology from the University of Göttingen. Just some of these have undergone a clinical trial.
They tested nine supplements
In a randomized and controlled clinical trial, led by Dr. Ellrott team studied the effects of new weight-loss supplements that were compared with those obtained placebo. Supplements covered were: L-carnitine, those containing cabbage powder, powder of stones of guarana, extract bean extract from the Konjac Root, dietary fiber pills, formulas with sodium alginate and extracts of selected plants .
To check their effect, experts have tested 189 obese and overweight patients who received either one of these supplements or placebo pills effect. Experiment lasted eight weeks, the dosage is carefully controlled and determined according to the directions specified on packaging.
1 – 2 kg lost after 2 months, depending on each supplement
The results show that depending on each supplement, patients are weakened between 1 and 2 kg, the same effect is found in people who took pills with placebo effect. “Most studies conducted so far have examined only one product. This study is the first to include a new supplement for weight loss mechanism of action and concluded that none has the effects claimed by the manufacturer,” says Dr. Thomas Ellrott.
Green tea supplements, blacklisted
Another study presented at the International Congress of Obesity and other supplements added blacklisted products have no effect guaranteed by the manufacturer. Thus, the team led by British physician Igho Onakpoya University of Exeter and Plymouth has developed a list of other ineffective weight loss suplimete: the chromium Picolinate, efedra, bitter orange, conjugated linoleic acid, calcium, guar gum, glucomannan, chitosan and the green tea. “We have no proof that any of these weight loss supplements are a suitable treatment for weight loss. Moreover, experts have found in some cases adverse effects and support the need for extensive research to verify their safety.
