Caffeine is often included in fat-burning supplements the form of yerba mate or guarana — however, manufacturers may include these substances in amounts they’re rarely used otherwise. Caffeine is a common weight loss ingredient because it often has the effect of dulling someone’s appetite and help increase energy for activity. However, too much caffeine can cause side effects like jitteriness, headaches, insomnia, anxiety, heart palpitations, diarrhea and more.
This Asian veggie dish is made by fermenting a blend of cabbage, radishes, and scallions with a seasoned paste of red pepper, salted shrimp, or kelp (koji) powder. Fermented foods are great for healing your gut thanks to the high levels of probiotics, but the unique strains found in kimchi may also help you stay slim: Researchers at Kyung Hee University in Korea induced obesity in lab rats by feeding them a high-fat diet. The group that got a Lactobacillus brevis supplement— the culture strain found in kimchi—was able to suppress the diet-induced increase in weight gain by 28 percent! If kimchi isn't your thing, also consider adding one of these probiotic foods for a healthier gut to your diet.

A true gem when it comes to fat burning. Taking Green tea is a safe, natural way to boost your metabolism. In it you’ll find antioxidants also known as Catechins, these activate the fat burning hormone norepiphrine and help your body achieve greater weight loss through the process of ‘Thermogenesis’. This wonder leaf will help to reduce your appetite. It’s also a nice ingredient for women as it can help your body work against the fat storing hormone Erastidiol.
A handful of almonds packs a serious fat-burning punch: One International Journal Of Obesity and Related Metabolic Disorders study of overweight adults found that eating about a quarter-cup of almonds for 6 months led to a 62 percent greater reduction in weight and BMI, thanks to a compound that limits the fat absorbed by the body. And eating just 1.5 ounces of almonds daily led to a reduction in belly and leg fat, a 2015 study published in the Journal of the American Heart Association showed. For added effect, eat almonds before working out: The amino acid L-arginine can help you burn more fat while building muscle.
Sometimes, to whip your body into shape, you have to get a little nutty. While nuts are high in fat, it's that very fat that makes them such powerful weapons in the war against a ballooning belly. In fact, a study published in Diabetes Care revealed that study participants who consumed a diet rich in monounsaturated fats, like those in nuts, over a 28-day period gained less belly fat than their saturated fat-consuming counterparts while improving their insulin sensitivity.
Sure, ketchup is tasty, but it's also a serious saboteur when it comes your weight loss efforts. Ketchup is loaded with sugar — up to four grams per tablespoon — and bears little nutritional resemblance to the fruit from which it's derived. Luckily, swapping out your ketchup for salsa can help you shave off that belly fat at home without a diet. Fresh tomatoes, like those used in salsa, are loaded with lycopene, which a study conducted at China Medical University in Taiwan links to reductions in both overall fat and waist circumference. If you like your salsa spicy, all the better; the capsaicin in hot peppers, like jalapeños and chipotles, can boost your metabolism, too.
There’s a key difference between how supplements are regulated versus how medications or other drugs are. Dietary supplements are considered safe until proven unsafe, while the opposite is true of prescription drugs: They’re kept out of the public’s hands until clinical trials show they’re generally effective and also unharmful to the majority of patients taking them. 
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.
Launched in 2018, Hunter Burn is described as a ‘premium’ fat burner. It’s aimed at the top end of the market and is designed for those looking for larger doses and higher quality ingredients. This comes at increased cost – but does it deliver? Hunter Burn features the largest serving sizes we’ve ever seen, while also using more potent forms of certain key ingredients. Some will want the cheapest on the market. But this is a highly-researched formula for men who are happy to pay more to get the best.
One 2009 report published in the Journal of Nutritional Biochemistry found that CLA has positive effects on energy metabolism, adipogenesis, inflammation, lipid metabolism and apoptosis. (6) A 2007 study published in the British Journal of Nutrition similarly found that supplementation of a CLA mixture in overweight and obese people (three to four grams a day for 24 weeks) decreased body fat mass and increased lean body mass. (7) And regarding CLA’s safety, there seems to be very little risk for adverse effects on overall blood lipids, inflammation levels and insulin response in healthy, overweight or obese adults.
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.

To avoid feeling hungry after a workout, eat a snack with at least 12 grams of protein before exercising, says Dr. Cheskin. And if you’re still hungry afterward? First, check in with yourself and make sure it’s actual hunger and not dehydration, says Dr. Cheskin. Then, eat a protein-rich snack that also includes some carbs, like a protein bar with whole grains.
Red is one of the best colors for weight loss. That's because the color is due to higher levels of nutrients called flavonoids—particularly anthocyanins—which calm the action of fat-storage genes, according to Oxidative Medicine and Cellular Longevity research. In fact, red-bellied stone fruits like plums boast phenolic compounds that have been shown to "turn off" fat genes. Plus, their pectin—a gelatin-like type of fiber found in the cell walls of fruits—limits the amount of fat your cells can absorb, as shown by a Nutrition & Metabolism study.
The idea that men need supplements to burn fat is a complete myth, according to dietitian Dr. Chris Mohr. Supplements can give you a tiny boost when combined with the right diet and an intense training routine, but no supplement, pill or powder will magically burn belly fat, notes Mohr. Additionally, where you lose fat on your body is determined by genetics, so to lose belly fat, you have to concentrate on losing fat from every area 2.
Stop treating your kitchen like an all-night diner and you'll stop seeing those unwanted pounds piling onto your frame, too. The results of a study published in Cell Metabolism found that mice who only had access to food during an eight-hour period stayed slim over the course of the study, while those who ate the same number of calories over a 16-hour period gained significantly more weight, particularly around their middle. When you're finished with dinner at night, shut the fridge and don't look back until morning — your belly will thank you. When you do head back to the kitchen in the A.M., make sure the best healthy kitchen staples for cooking are there waiting for you.
Had enough of boring rice? Add some bulgur into your diet. Although this grain is traditionally used in tabbouleh—a staple dish of Mediterranean cooking made by combining bulgur with chopped parsley, garlic, diced tomatoes, olive oil, and lemon juice—you can also use it as a base of salad bowls or a side for a chicken dish. This cereal will help you burn fat thanks to boasting over eight grams of belly-filling fiber; A study published in the journal Annals of Internal Medicine found that by simply increasing the amount of fiber you eat each day (to 30 grams) while keeping calories the same could help you lose weight, lower blood pressure, and improve your body's insulin response as effectively as more complicated diets that try to overhaul your entire diet.
If you've got weight to lose and you want it gone fast, try swapping out your usual proteins in favor of fish. Not only is fish lower in calories than an equivalent amount of beef or chicken, a study published in Obesity reveals study subjects who added omega-3 fatty acids, like those found in fish, to their diets shed more weight and had an easier time keeping it off than those who skipped them.
If you’re only getting a minimal amount of sleep each night, that leaves more time for you to snack and make otherwise unhealthy decisions that could affect your weight loss. Although it will vary from person to person on how much sleep you actually need to be most effective (and therefore make progress toward your weight loss goals), the ideal number is typically seven or eight hours, says Dr. Cheskin.

There are tons of supplements available, but not all of them keep your overall happiness and health as a top priority. Some fat burners may be effective at burning fat, but they may make you hungry all the time. When this happens, you may either feel like you are starving, or it will make you eat more and gain the weight right back. Other supplements may make you feel weak and energy deprived. This makes it hard to function throughout the day and can make exercise much less effective.
Although their efficacy and safety are constantly scrutinized by the FDA and other organizations, manufacturers of thermogenic “diet pills” often claim that taking these supplements can help improve weight loss almost effortlessly by boosting your metabolism (the rate at which you burn calories). Some may also be at least somewhat helpful for decreasing your appetite, curbing cravings for junk foods and giving you more energy, which can be used for physical activity.
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.
After your diet, and once you cycle off of your fat burner, it's important to bump your calories back up to or above what is known as "maintenance," where your calories and calorie burn are roughly equal. One popular way to do this is what is known as a "reverse diet," where you gradually and systematically raise calories. Registered dietician Katie Coles explains how in her article "The Ultimate Guide to Reverse Dieting."
Whether it's turning off fat genes, helping to build muscle that robs energy from adipose cells, revving your metabolism and ability to burn fat, or helping you feel fuller longer so you consume fewer calories, these foods have been proven to show an increased rate of fat loss. So stop these bad habits that give you belly fat, and instead, incorporate these healthy fat burning foods into your diet to whittle your waist and bring your midriff back in line.

This review is for the originally released Shred Sport, which was just a rebranding of Shred Matrix, and since the formulas were the same this review could be applied to either one. That said, Shred Sport has made a significant reformulation since then, although we will not be updating with a review for that newest version since completely changing the formulation means you now have a completely different product. In other words: enjoy our Shred Matrix review…
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.

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.

The main ingredient in most fat burners is caffeine, which helps you lose weight by increasing your metabolism and helping the body use fat for fuel. It also helps provide energy for exercise and other calorie-burning activities. In the body, caffeine increases the breakdown of fatty acids that reside in adipose tissue—also known as belly fat. Once the fatty acids are broken down, they enter the bloodstream and can be burned up by our bodies to create energy.
Still, it’s a worthy goal to lose belly fat because it’s “unfortunately the most dangerous location to store fat,” says Lawrence Cheskin, M.D., chair of the department of nutrition and food studies at George Mason University and associate professor of health, behavior & society at Johns Hopkins University. Because belly fat—also known as visceral fat, or the deep abdominal fat that surrounds your organs—is more temporary, it circulates throughout the bloodstream more regularly and is therefore likelier to raise the amount of fat in your blood, increasing your blood sugar levels and putting you at a greater risk of heart disease and type 2 diabetes.
