Remember the when low-carb, high-protein diets (a la the Atkins Diet) were all the rage? Good. Because they’re back, with a serious endorsement from the National Institutes of Health. Anahad O’Connor reports in the New York Times that a one-year study of 150 people conducted at Tulane’s School of Public Health and Tropical Medicine (and funded by NIH) found that people who eat fewer carbohydrates and more fat lose more body fat and and have fewer cardiovascular risks that people who follow a low-fat diet. O’Connor tells us that at the end of the yearlong trial, those in the low-carbohydrate group had lost about eight pounds more on average than those in the low-fat group. They also had significantly greater reductions in body fat than the low-fat group, and improvements in lean muscle mass — even though neither group changed their levels of physical activity. Wait, there’s more: While the low-fat group did lose weight, they appeared to lose more muscle than fat. Yes, that’s a bad thing. The Times reports that those in the low-carb group also saw markers of inflammation and triglycerides plunge, and their HDL, the good cholesterol, rose more than it did for people in the low-fat group.
