The weakness of the four-food-groups approach is that it doesn’t provide enough guidance to prevent you from eating too much fat and amassing too much of it on your body.
If you make fat-fighting your number one priority, however, it quite naturally leads you toward fulfilling those other guidelines. “If you phase out the high-calorie, high-fat foods in your diet, you’re going to have to replace them with something low-fat—cereals, fruits and vegetables,” says Dr.Blackburn. An emphasis on those foods moves you closer to meeting your RDA for vitamins and minerals. It can also move you closer to balancing your diet, which for most Americans is overladen with high-fat meat and dairy products.
