Following a low-carbohydrate, high-protein diet is a more effective way to lose weight than following a low fat diet, say US researchers. Two studies published in the journal Annals of Internal Medicine found weight loss was greatest when people followed an Atkins-style diet. Cholesterol levels also seemed to improve more on a low-carb diet compared to a low-fat diet. However, the research was funded by the Robert C Atkins Foundation. And critics say there are still serious doubts about the long-term effect on health of adopting such diets.
