It's not just about weight, but also about composition. From the article: While the low-fat group did lose weight, they appeared to lose more muscle than fat. “They actually lost lean muscle mass, which is a bad thing,” Dr. Mozaffarian said. “Your balance of lean mass versus fat mass is much more important than weight. And that’s a very important finding that shows why the low-carb, high-fat group did so metabolically well.” > learning about caloric content and restricting yourself in calories is much easier than following a diet Apart from cutting out certain foods, the low carb high fat group was allowed to eat how much they pleased. Sounds way easier than counting calories all the time.
