Low fat diets do not slim down more than others
Diets low in fat do not make more weight loss in the long term than other weight loss diets, according to a study that comes to animate debate on the best way to lose weight or a few extra pounds.
There is “no evidence to recommend low-fat diets,” says lead author Dr. Deirdre Tobias (Brigham and Women’s Hospital and Harvard Medical School, Boston, Massachusetts, USA) on the basis of This analysis of 53 scientific studies , covering nearly 70,000 adults from several countries.
“Science does not support low-fat diets as the optimal long-term weight loss strategy,” he says.
In fact, low- carbohydrate diets (sugars and other complex carbohydrates, such as starchy starch) make it possible to lose more weight, about 1 kilogram, than that obtained (360 grams) with Diets low in fat after a year, according to this work published Friday in the journal The Lancet Diabetes & Endocrinology .
While overweight and obesity are increasing in the world alarmingly, identifying effective strategies for weight control becomes crucial.
Fat reduction and weight loss: a misconception according to specialists
Dietary fats have long been the target of diets for various reasons, especially because each gram of fat contains more than twice the calories than one gram of carbohydrates or protein (9 kcal or calories / g vs 4) Authors. And they are the subject of contradictory studies.
Dietary advice recommending to eliminate fat is based on “the idea that simply reducing fat intake will naturally lead to weight loss,” says Dr. Tobias in a statement. But he believes that his study brings “strong arguments” indicating that this is not the case.
“What seems clear is that adherence to the diet over the long term is catastrophic, regardless of whether they are low-fat diets or other diets that are prescribed,” writes A commentary published with the study, Kevin Hall of the National Institute of Diabetes and Digestive and Kidney Diseases (Maryland, USA).
The best diet is to eat less and do more exercises , according to specialists. “For me, the message of this study is that energy intake determines the importance of weight loss rather than the relative proportions of lipids and carbohydrates in the diet,” says Tom Sanders of King College in London, via the Science Media Center.
