Consider them “good carbs”. Their bulk takes up space in your stomach, helping you feel full and eat less. The top fiber food: beans, which contain 8g per 1/2 cup. Research shows that guys who added 12g of fiber a day to their diet lost a quarter of an inch from their love handles, without otherwise modifying their diet. Here are some of the best sources.
Stephen Colbert may be on to something. UCLA Center for Human Nutrition researchers divided study participants into two groups, each of which were fed a nearly identical low-cal diet for 12-weeks. The only difference between the groups was what they were given to eat as an afternoon snack. One group ate 220-calories of pretzels while the other group munched on 240-calories worth of pistachios. Just four weeks into the study, the pistachio group had reduced their BMI by a point, while the pretzel-eating group stayed the same, and their cholesterol and triglyceride levels showed improvements as well.
The popular "flat belly diets"embrace much of the wisdom found in eating a Mediterranean diet, which helps everything from brain health to hearth health. The basic premise for both diets is eat foods rich in monosaturated fatty acids (MUFA) that may help reduce your belly fat storage. MUFA-rich foods include olive oil, nuts and seeds, avocodos, and fish. Eating yogurt regularly has also been found to be helpful in reducing belly fat.
Cons: Eating this way perpetuates the outdated idea that dietary fat is the enemy of body fat. And it isn’t necessarily better than other diets: One study in the American Journal of Clinical Nutrition compared high-protein, normal protein, high-fat, and low-fat diets, and found no significant difference in fat loss among the groups at six months or two years (though all did result in some fat loss). What’s more, while the low-fat group was supposed to keep its intake of the macro at 20%, actual intake was closer to 26-28%, suggesting that sticking to a strict low-fat diet is rather difficult and potentially unrealistic for most.
All you need is a pair of sneakers before you head out the door. But if weight loss is the name of your game, the lackadaisical head-out-for-a-light-jog style of running isn't the way to go. Instead, find a hill you can sprint up, or crank the incline on that treadmill. "Running up hills forces you to work your glutes and legs—two of your body's biggest muscle groups—even more, which requires smaller muscle recruitment and more energy expenditure," explains Rosante. As noted earlier, the more energy you're using, the brighter that calorie-burning fire burns. But proper form here is key. "Lean into the hill, and drive your knees as high as you can, striking the ball of each foot down directly under your body," he says. "Keep your hands open and arms bent at 90 degrees, and drive your arms straight forward up to face level, then backward to the top of your back pocket." And try not to let your arms cross over your body—that'll just waste the precious energy your muscles need. If you're training indoors, here are a few fat-burning treadmill routines to get you started.
