Dietary Supplement Doesn’t Contribute to Weight Loss

The new research shows a lack of strong evidence that Dietary Supplement and alternative therapies help adults lose weight .The flagship journal of The Obesity SocietyThere are hundreds of weight-loss supplements like green tea extract, chitosan, guar gum and conjugated linoleic acid, and an estimated 34% of Americans who are trying to lose weight have used one.Researchers completed a detailed review of 315 existing clinical trials of Dietary Supplement and therapies. Most of the studies showed the supplements did not produce weight loss among users.

John Batsis, MD, associate professor in the Division of Geriatric Medicine at the University of North Carolina School of Medicine, and in the Department of Nutrition at the UNC Gillings School of Global Public Healthand the corresponding author of the study said that the findings are important for clinicians, researchers, and industry alike as they suggest the need for rigorous evaluation of products for weight loss. After that they can produce data that allows clinicians to provide input and advice with a higher degree of certainty to our patients.

Dietary Supplement Doesn’t Contribute to Weight LossBatsis added that the evaluation should also be collective as the supplement industry and academics work together to design high-quality clinical trials of weight loss supplements.The paper’s authors explain that patients often strive to lose or maintain weight either because of a lack of efficacy of existing Federal Drug Administration-approved therapies or a lack of access to healthcare professionals who provide treatments for obesity.

Researchers focused on 315 peer-reviewed randomized-controlled trials and analyzed them for risk of bias. Results classified 52 studies as low risk of bias and sufficient to support efficacy. Of these, 16 studies demonstrated significant pre/post intergroup differences in weight compared with placebos. In these methodologically distinct studies, the weight loss ranged widely from 0.3 to 4.93 kg.
