The fat-burning equation is simple: Protein builds muscle. More muscle = more fat burning. And fish is one of the healthiest sources of lean protein—especially wild salmon, says dietitian Lauren Minchen, MPH, RD, CDN. It’s also a rich source of anti-inflammatory omega-3 fatty acids, which fuel fat burning, block fat storage and aid weight loss, she explains. But that’s not all: “Getting enough protein and healthy fat also helps to reduce cravings and has been shown to help keep weight off for longer,” adds Alissa Rumsey, MS, RD, CDN, CSCS.
It is agreed that milk can really give you a positive effect when it comes to burning belly fat. According to a research of the researchers at the University of Alabama in Birmingham in 2010, among more than 100 premenopausal women participating the survey, fat in women who consumed foods high in calcium was significantly reduced. In fact, when you consume 100 milligrams of calcium per day, they will remove many bad agents around and in your internal organs which have been related to the rate of cancer or heart disease.
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.
Kickstart your morning—and your metabolism—with this warming spice. Cinnamon contains powerful antioxidants called polyphenols that are proven to alter body composition and improve insulin sensitivity (which means it keeps blood sugar stable, preventing hunger-inducing spikes and crashes). Japanese researchers found that mice who ate a daily helping of cinnamaldehyde (the ingredient that gives cinnamon its flavor) lost belly fat, while those who skipped the spice did not. Add it to your overnight oats or sprinkle some in your coffee to reap the benefits. 

Do you even lift, bro? If you’re serious about getting rid of that belly fat fast, resistance training might just be the key. A study from the Harvard School of Public Health found that adding weight training to adult male test subjects’ workouts significantly reduced their risk of abdominal obesity over a multi-year study period, although doing the same amount of cardio had no such effect. Research from the University of Maryland even found that just 16 weeks of weight training boosted study participants’ metabolic rates by a whopping 7.7 percent, making it easier to ditch those extra inches around your middle.
Some cheat meals are better than others. And a high-carbohydrate, moderate-protein meal, however “naughty,” can help you stay on track. The reason: Carbohydrates have the greatest influence on leptin levels, which help you burn fat and feel satisfied. And protein has the greatest influence on satiety because of its influence on appetite-regulating hormones and high thermic effect—the process of digesting protein requires more energy of your body than any other macronutrient. So, go ahead and grab a bowl of spaghetti and meatballs. Contrary to popular belief, pasta is actually a fairly low-glycemic food, meaning it won’t drastically spike your blood sugar levels.
Another reason is the genetic factor. In case obesity runs in the genes, it will take place and it cannot be helped. Excessive calorific intake transforms into fat and calories, so the more junk food you eat, the fatter you get. Stress is another indicator of belly fat accumulation. As it is human nature to eat more during stressful times, this tends to add up the calorific intake. Another factor influencing belly fat is a lack of sleep which results in the gas formation and puffing up of the belly.
The leafy green is jam-packed with energy-boosting nutrients such as vitamin A, iron, and folate. It can also reduce your appetite—helping to curb your calorie intake and encourage your body to start burning fat—thanks to natural compounds called thylakoids. Swedish researchers found that over three months, women who consumed a five-gram thylakoid supplement from spinach reported a 25 percent reduction in hunger and cravings and significantly more weight loss (11 pounds) than the control group!
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.
Resolve to do more prying. Oysters are one of the best food sources of zinc, a mineral that works with the hormone leptin to regulate appetite. Research shows that overweight people tend to have higher levels of leptin and lower levels of zinc than slimmer folk. A study published in the journal Life Sciences found that taking zinc supplements could increase leptin production in obese men by 142 percent! A half-dozen oysters only have 43 calories but provides 21 percent of your RDA of iron—deficiencies of which have been linked to a significant increase in fat gene expression.
This is a top quality protein source that lowers body fat and leads to maintenance of muscle mass. High quality protein is perfect for supporting weight because it contains amino acid leucine. This amino acid cuts down the calories and builds muscles. If compared to fats or carbs, proteins promote greater satiety. It helps in cravings as well. Protein is perfect for reducing cravings and improving the desire for snacks. Increasing protein intake has been a process for the ability to reduce cravings drastically and snacking at night. Protein has thermogenic properties which burn calories the food contains during the digestion.

The phrase “slow carb” is anything but sluggish when it comes to blasting fat. Slow carbs are digested slowly, which keeps you feeling fuller and energized longer—and sweet potatoes are one of them. Among the magic ingredients here are carotenoids, antioxidants which stabilize blood-sugar levels and lower insulin resistance, which helps your body efficiently convert calories to energy rather than stored as fat. And their high vitamin profile (including A, C, and B6) give you more energy to burn at the gym.

This classic lunchbox sandwich condiment is teeming with flat-belly nutrients such as cholesterol-lowering monounsaturated fats and is a great source of plant-based protein. According to a recent study presented at the annual Society for Endocrinology conference, researchers found that when protein is digested and broken down into amino acids in your body, one of those amino acids—phenylalanine—triggers hormones that help reduce appetite and ultimately leads to fat burn and weight loss.
