If you want to shrink your gut, get enough protein in your diet. In this case, about 25 percent of calories. Why? For starters, protein makes you feel full and helps you build muscle (which increases metabolism, thereby making it easier to lose weight). Just as important, high-protein diets have been shown to be the best way of attacking belly fat. In one study, published in the International Journal of Obesity, Danish researchers put 65 people on either a 12 percent protein diet or a 25 percent protein diet. The low-protein dieters lost an average of 11 pounds, which isn't bad. But the high-protein subjects lost an average of 20 pounds--including twice as much abdominal fat as the low-protein group.
You might think passing on lunch will save calories and trim your middle, but you're actually trending toward the opposite. Going long periods of time without eating can send your body into starvation mode, meaning it starts storing everything you've already eaten as fat since it doesn't know when you're going to feed it again. And guess where that chub piles on first? Yup. Your midsection. Experts say having a small meal or snack every three hours will keep your body fueled and in prime calorie-torching mode all day.
Support your weight loss and exercise program by getting between 1.2 and 1.6 grams of protein per kilogram (or 0.55 and 0.73 grams per pound) of your body weight, recommends research published in the American Journal of Clinical Nutrition in 2013. For a 200-pound woman, this would suggest you aim for 110 to 146 grams of protein daily, split up among three to five meals.
This just in: Saturated fat packs on more visceral fat than polyunsaturated ones, according to a recent Swedish study. When subjects ate 750 more calories daily for seven weeks—either in the form of palm oil (saturated) or sunflower oil (polyunsaturated)—the former gained more visceral fat while the latter gained more muscle mass and less body fat. Polyunsaturated fats can be found in nuts, seeds, and fish.
While it’s often assumed that bread is off-limits when you’re trying to lose belly fat, the right bread may actually expedite the process. Switching to sprouted bread can help out carb-lovers eager to get their fix without going up a belt size, thanks to the inulin content of sprouted grains. The results of a study published in Nutrition & Metabolism reveal that found that pre-diabetic study subjects whose diets were supplemented with inulin shaved off more belly fat and total weight than those whose meal plans didn’t pack this healthy prebiotic fiber.
