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.
Apple cider vinegar, in particular, is composed mostly of acetic acid, which has been shown to delay gastric emptying and slow the release of sugar into the bloodstream. Research published in the journal Bioscience, Biotechnology, Biochemistry found that a small pool of study participants given ACV over a 12-week period lost more weight, body fat and inches from their middle than participants that were given a placebo. How does it work? Besides maintaining stable blood sugar levels, ACV produces proteins inside the body that burn fat.
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.
“Starting slow and working your way up is better than overdoing it and giving up,” says Gagliardi. “I like the idea of attaching the new behavior of taking a walk to an existing behavior.” An easy way to approach it: Commit to going for a quick 10-minute walk after dinner, and slowly increase the time as you become more comfortable with daily movement.
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.
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. Go for brands that have an ingredient list of just two items: nuts and a little salt, or look to our guide: Best and Worst Peanut Butters.
While many people turn to artificial sweeteners in a misguided attempt to whittle their waistlines, those fake sugars are likely to have the opposite effect. According to Yale researchers, artificial sweeteners are actually linked with an increased risk of abdominal obesity and weight gain, possibly because they can trigger cravings for the real stuff and spike insulin levels in a similar fashion to real sugar.
Though green tea is not caffeine rich, it does contain around 25 to 50 mg of caffeine in a cup. The green tea contains EGCG or epigallocatechin gallate. This boosts the metabolism. It also leads to powerful antioxidant properties supporting the norepinephrine in the brain sending signals to the body to break down fat cells and use fat which is on your body for energy. Consuming green tea along with exercise is the perfect way to burn your belly fat.
Not all white foods are bad for weight-loss. In fact, plain boiled potatoes are the most filling food there is, according to the Satiety Index of Common Foods, an Australian study published in the European Journal of Clinical Nutrition. To maximize their flat-belly benefits, throw ’em in the refrigerator and make a potato salad. The cooling process will crystallize the tubers into resistant starch, which takes longer to break down in your intestine, producing fat-burning butyrate and delaying hunger pangs.
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!
Citrus fruits contain the fat-burning nutrients fiber and vitamin C. Vitamin C stimulates your body's fat-burning capability found in the carnitine amino acid, according to Fat Free Kitchen. Vitamin C plays a role in your body's fat processing capability. This nutrient speeds the process up by diluting the fat and then eliminating it from your body. Eat a variety of fiber and vitamin C-rich citrus fruits to increase your metabolism and burn fat. Citrus fruits include grapefruit, guava, lemons, limes, oranges, tangerines, papaya and tomatoes. Drinking juices made from these fruits can also help burn fat.
This brilliantly orange root is a powerful fat fighter. According to a 2009 study by the USDA, mice whose diets were supplemented with turmeric experienced reduced weight gain and body fat levels even when their food intake was not changed. Experts believe the power of this spice comes from the active ingredient curcumin: Studies, including one published in the journal Journal of Traditional and Complementary Medicine, have found that curcumin is one of the most effective anti-inflammatory options out there. Because it’s more difficult for your body to lose weight when you’re fighting off inflammation, adding anti-inflammatory turmeric will help you achieve your weight loss goals.
