You don’t have to be the next Usain Bolt in the making to enjoy some serious belly-slimming results from hitting the track from time to time. Even a moderate-rate jog a few times a week can blast through that belly fat; in fact, a study conducted at Duke University Medical Center found that, over the course of an eight-month study, overweight adult study subjects who jogged 12 miles a week lost the most belly fat and burned 67 percent more calories than participants who did an equivalent amount of resistance exercise, or a combination of cardio and resistance work.
Many teas have been shown to boost metabolism, block the creation of new fat cells, speed the release of fat from cells, and actually turn off fat genes due to their catechin levels, but green tea has a leg up on the competition. This magical elixir is particularly high in the antioxidant ECGC, the compound that burns fat and stops it from forming. Pair your tea with a workout for a fat-burning bonus. Exercisers who drank four to five cups of green tea daily and worked out for 25 minutes lost more belly fat than their non-tea-drinking counterparts, a study published in The Journal of Nutrition found.

The researchers explain that people who cook their own meals may simply have other good-for-you habits, like exercising more. However, they also concluded that home cooks ate more fruits and vegetables (along with a wider variety of foods), have healthier methods of prepping their food, and splurge less on foods high in calories and sugar.

Don’t let extra hours lounging in bed stand between you and a flatter stomach. While getting enough sleep can help boost your metabolic rate, sleeping in may undo any benefit you’d enjoy from catching a few extra winks. One Obesity study reveals that late sleepers who snoozed past 10:45 in the morning ate nearly 250 more calories over the course of the day, despite eating half as many fruits and vegetables as their early bird counterparts. Even worse, they chowed down on more salty, sugary, and trans-fat-laden fast food than those who woke up earlier. If you happen to head out of the house early, you’re in for an additional metabolic boost; researchers at Northwestern University have found that people exposed to just a short period of early morning sunlight had lower BMIs than their late-waking counterparts.
Keeping a toothbrush handy can do more than polish up that smile (and counter the effects of all that belly-slimming garlic); brushing your teeth throughout the day can also help you ditch that belly fat fast. A study conducted a sample of over 14,000 participants found that brushing after every meal was linked to lower weight. That minty toothpaste flavor not only clashes with virtually every food, brushing may also trigger a Pavlovian response that tells your brain the kitchen’s closed.
Whole grains contain nutrients that burn fat by keeping your insulin levels low, according to the New York Daily News. Whole grains provide excellent sources of complex carbohydrates and fiber, both beneficial in stimulating your metabolism. This results in burning more fat and calories, according to Fat Free Kitchen. Whole grains include whole wheat, barley, brown rice, quinoa, spelt, kamut, wheat bran and wheat germ. Eating a bowl of oatmeal in the morning will both fill you up and start your day energized. A late night snack of a whole grain fruit-filled bar will help your body burn calories while sleeping.
Fruits make it to the top of this list. The emphasis on fruits continues through this guide. When berries are concerned, the deeper color means more antioxidants to break starch into simple sugars, ensuring lower blood sugar levels. This helps in body fat loss because insulin essentially puts sugar in adipose or fat cells. Raspberries contain ketones that are rich in fat burning capability. Blueberries lower cholesterol, improve insulin and blood sugar levels for the better, and are a top source of fiber, lower in calories to ensure fat burning foods work wonders. Berries also fend off infections and maintain excellent vision, maintaining bone density.
But you'll lose the most fat by doing HIIT, or high-intensity interval training. This training technique involves working at full throttle for short intervals -- typically 10 seconds to a minute -- then recovering at a slow pace or resting for a minute or two. It increases your metabolism after a workout, since your muscles need to work hard to get "back to normal." HIIT also burns more belly fat than traditional, steady-pace cardio, according to Penn State University. 

Each slice of grapefruit you add to your salad acts like a match to spark your body’s fat-burning ability. A study published in the journal Metabolism found that those who ate grapefruit for six weeks lost a full inch off their waistlines. What’s behind the belt-tightening effect? The fruit is rich in phytochemicals, bioactive compounds that recent research shows stimulate the production of a hormone called adiponectin, which is involved in the breakdown of body fat. Japanese research suggests the smell of the juicy fruit can “turn on” calorie-burning brown fat cells, promoting the breakdown of body fat while reducing appetite.
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.

Use an adult energy needs calculator to estimate your calorie intake needs; then subtract the 500 to 1,000 calories for weight loss. For example, a 28-year-old woman who is 5 foot, 9-inches tall weighs 175 pounds and is lightly active -- less than an hour a day -- burns about 2,400 calories daily. She'll burn about 2 pounds of fat in a week if she eats 1,400 calories daily, or 1 pound a week if she eats 1,900 calories a day.
