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.
A little garlic in your meals could mean a lot less weight around your middle. The results of a Korean study found that mice given a high-fat diet supplemented with garlic lost significantly more weight and abdominal fat than those who just ate fatty foods. Even better, they also improved their liver health, making it easier to stay healthy and burn off that excess fat in the long term. For more flavorful ways to make your food more enjoyable, turn to the metabolism-boosting spicy recipes and watch those pounds melt away.
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.

According to the School of Sport and Exercise Sciences at University of Birmingham, “The term ‘fat burner’ is used to describe nutrition supplements that are claimed to acutely increase fat metabolism or energy expenditure, impair fat absorption, increase weight loss, increase fat oxidation during exercise, or somehow cause long-term adaptations that promote fat metabolism.” (3)


Ansari says alcohol can prevent weight loss in several ways, including the fact that heavy alcohol intake can stimulate food intake. "Binge drinking can overload the liver. The liver then prioritizes processing alcohol over other nutrients and then stores the protein, carbs, and fat as fat in the body," Ansari explains. The Centers for Disease Control and Prevention (CDC) defines binge drinking as having five or more drinks for men, and four or more drinks for women in two hours. "Also, alcoholic beverages are often mixed with sugar-rich beverages. Drinking more than moderate amounts of alcohol can cause calories to add up quickly," she says.


Most fat burners will suggest taking at least two doses spread out throughout the day. The timing of these doses is also important. It is usually advised to take doses right before breakfast and lunch. This will allow them to kick in to help you feel full after meals and will give you energy throughout the day. But be sure not to take them late in the afternoon or at night, otherwise they might end up keeping you awake. Getting a good night’s sleep is also an important part of losing weight. Remember that one.

"I encourage people to cycle their fat burners," Kendall explains. "People are typically on a fat burner for 4-6 weeks. Once your body gets used to it, you're not going to see the same increase in fat oxidation or increase in metabolic rates. By stopping using your fat burner every now and then, you make sure it will still help you lose belly fat."

If you thought losing weight would mean giving up all your indulgences, look no further than dark chocolate. Louisiana State University researchers found that gut microbes in our stomach ferment chocolate and boost our body's production of gut-healthy polyphenolic compounds, including butyrate, a fatty acid that encourages the body to burn fat as fuel and turns off genes linked to inflammation. (Add fruit to the chocolate to boost fermentation and the release of the compounds.) Make sure you go with chocolate that has a cacao content of 70 percent or above—these have the highest concentrations of antioxidant polyphenols.
Research suggests these magical pulses are one of the closest things we have to a fat-burning pill. For starters, beans are a great source of resistant starch, a type of slow-digesting, insoluble fiber that feeds the healthy bacteria in your gut, triggering the production of the chemical butyrate, which encourages the body to burn fat as fuel and reduces fat-causing inflammation. They're also one of the top sources of soluble fiber. A recent study by Wake Forest Baptist Medical Center researchers found that for every additional 10 grams of soluble fiber eaten per day, a study subject's belly fat was reduced by 3.7 percent over five years. Black beans? One cup boasts an impressive 4.8 grams of soluble fiber.
Fat burners are seen by some as “magic pills” that will make your extra fat fall right off. In actuality, there is no such thing. However, these pills can boost your energy, help you control how much you eat, and keep you motivated each and every day. If you use a fat burner correctly, it can give you the extra help you need to reach your health, weight, and fitness goals. Here is everything you might need to know about fat burners and how they work.
