We'll take the egg, bacon and cheese tomorrow morning and skip the muffin altogether. Why? Because there's more ammo for the low-carb diet we've been hankering to try. Turns out that obese people whose carbohydrates were restricted, but who could chow down on as much fat and protein as they wanted, lost and kept off as much weight as those on a low-fat diet after two years, a new Temple University study finds. Gary Foster, director of Temple’s Center for Obesity Research and Education, told NPR's "Shots" blog that the study "tells us that people wanting to manage their weight need to be less concerned with which diet they choose, and more concerned with incorporating behavioral changes into their plan."
