Bump up your burn
Your muscles can use only 30 grams of protein at any time, a study in the Journal of the American Dietetic Association notes. Any more than that gets stored as fat. Aim for a minimum of 46 g of protein per day. A sample menu: Breakfast: 6 ounces lowfat yogurt with 1/2 cup berries and a medium skim latte (23 g) Lunch: Spinach salad with 2 oz chicken and 1/3 cup black beans, served with pita with 2 tbsp hummus (30 g) Dinner: Asian stir-fry with 1/3 cup each tofu, snow peas, red bell peppers, bok choy, bean sprouts and 3/4 cup brown rice, sprinkled with 2 tbsp slivered almonds (23 g)
