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.
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.
All animal proteins are also a good source of tryptophan, which is a precursor to the neurotransmitter serotonin. “If you struggle with mood or stress, it’s important to boost the production of serotonin to stabilize your mood, curb emotional eating, and keep stress-induced snacking at bay," especially when you’re trying to lose weight, says Cording. But when it comes to portions, opt for a 100 gram serving, which is about the size of a deck of cards, for reference.
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.
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.
Say cheese! Adding some extra calcium and vitamin D to your diet could be the best way to get the flat stomach you’ve been dreaming about. Over just 12 months, researchers at the University of Tennessee, Knoxville found that obese female study subjects who upped their calcium intake shed 11 pounds of body fat without other major dietary modifications. To keep your calcium choices healthy, try mixing it up between dairy sources, calcium-rich leafy greens, fatty fish, nuts, and seeds.

It’s a dietary miracle: A fat that makes you skinny. Dietary supplementation of coconut oil actually reduced abdominal obesity in a study published in the journal Lipids. Of the participants, half were given two tablespoons of coconut oil daily and the other half were given soybean oil, and although both groups experienced overall weight loss, only the coconut oil group saw smaller waistlines. And other researchers have also pointed to the waist-whittling effects of the tropical oil. In a separate study of 30 men, those who ate 2 tablespoons of coconut oil a day shrank their waists by an average of 1.1 inches in one month. Thank C.O.’s medium-chain triglycerides, which are burned as energy instead of being stored as fat, and lauric acid, which has been shown to pinpoint belly fat and torch it.

Sunny side up, scrambled, hard-boiled, or fried—it doesn’t matter. A pan, spatula, and carton of eggs are all you need to fry some serious flab. Eggs are one of the best sources of choline, a major fat-burning nutrient that helps turn off the genes responsible for belly-fat storage. Bonus: eggs are a great source of lean protein, which can set the fat-burning pace for your entire day when eaten for breakfast. In a study of 21 men published in the journal Nutrition Research, half were fed a breakfast of bagels while half ate eggs. The egg group were observed to have a lower response to ghrelin, were less hungry three hours later and consumed fewer calories for the next 24 hours!

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.


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.
