Low-fat diets do not yield greater weight loss than other slimming regimes, said a study Friday, adding to the long-running debate on how best to shed extra pounds or kilos. In fact, low-carbohydrate diets led to greater weight loss than low-fat ones, according to study results published in The Lancet Diabetes & Endocrinology journal. Weight loss on a low-fat diet was just 360 grammes (13 ounces), compared to 1.15 kilogrammes (2.5 pounds) on a higher-fat, low-carbohydrate eating plan.
