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.
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.
Weightlifters – Weightlifters, bodybuilders and fitness enthusiasts can greatly benefit from these products. Because of the higher-than-average calorie and nutrient needs of regular trainers, it can be easy to put on some extra fat while you’re building muscle. By adding a weight loss supplement, you can get that toned definition you’re after, without sacrificing your muscles.
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)
L‐carnitine: This stimulant-free amino acid has been physique athletes' secret weapon for decades. Taken once or twice daily with food, it can also help your body convert stored body fat into energy, leaving you leaner and more defined. It does this by breaking up fatty acids so the body can use them for fuel. As Jim Stoppani, Ph.D., explains in "Your Expert Guide to L-Carnitine," it has also been shown in studies to support recovery from workouts, reduce muscle damage, and even reduce exercise-induced muscle soreness.
How could the “fatty” foods mentioned above that contain CLA be good for reducing body fat? The jury is still out regarding the effects of CLA on promoting weight loss, but results from certain studies suggest that CLA (taken either alone or along with supplements like creatine and whey protein) can help increase strength, reduce appetite and cause other beneficial changes in body composition.
Many teas have been shown to boost metabolism, block the creation of new fat cells, speed the release of fat from cells, and actually turn off fat genes due to their catechin levels, but green tea has a leg up on the competition. This magical elixir is particularly high in the antioxidant ECGC, the compound that burns fat and stops it from forming. Pair your tea with a workout for a fat-burning bonus. Exercisers who drank four to five cups of green tea daily and worked out for 25 minutes lost more belly fat than their non-tea-drinking counterparts, a study published in The Journal of Nutrition found.
Those trans fats on your menu are hiding out in plain sight and sabotaging your lean belly plans every time you eat them. If a food product says it contains partially hydrogenated oils, you're eating trans fat, which can increase your risk of heart disease, high cholesterol, and obesity with every bite. In fact, research conducted at Wake Forest University reveals that monkeys whose diets contained eight percent trans fat upped their body fat by 7.2 percent over a six-year study, while those who ate monounsaturated fat gained just a fraction of that amount. Instead of letting harmful trans fat take up space on your menu, fill up with these healthy fats.
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.

Known as "forbidden rice" because only emperors were allowed to eat it, black rice may be the cheapest source of antioxidants around. According to the American Chemical Society, black rice has more antioxidants than a spoonful of blueberries, with more satiating fiber, more vitamin E, and less sugar. More antioxidants mean less inflammation, which means less fat storage for you.
