The New England Journal of Medicine has just published a new diet study that is already causing plenty of debate (see the Wall Street Journal’s take on it, for example). The investigators put about 100 people each on one of three diets: low-fat, low-carbohydrate, and Mediterranean. After two years, everybody lost about 6-10 pounds. The low-carb people did best, the Mediterraneans came next, and the low-fat people lost the least – but the differences were not great. The low-fat diet was not really low in fat (30% of calories) but it doesn’t matter. Everybody reduced caloric intake, increased physical activity, lost some weight, and made some metabolic improvements. One funny thing: the study was funded by the Atkins Foundation but the low-carb people were counseled to choose vegetarian sources of fat and protein, not meat. So this was not a test of the Atkins diet. My interpretation: eat less, move more works, and you have choices about how to do the “eat less” part.
