Keto diet has greater health benefits than other popular weight-loss diets, according to clinical trial

A diet that severely limits carbohydrates but is high in fat has the greatest health benefits for people with obesity compared with a Mediterranean diet or a low-fat diet, according to a clinical trial published Aug. 27 in the journal Cell Metabolism. After following a ketogenic (or "Keto") diet for four to five months, about 50% of a group of participants with obesity and prediabetes no longer met the criteria for prediabetes.
