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)

Top your salad with this lean protein and soon enough all your friends will be asking you to tuna-round so they can compliment your new slimmed down look. As a primo source of docosahexaenoic acid (DHA), canned light tuna is one of the best and most affordable sources of lean protein for fat loss, especially from your belly! One study in PLOS One showed that omega-3 fatty acid supplementation from fish oil was connected to a lower waist-hip ratio as well as lower levels of abdominal fat.
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.

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.
Green tea extract: Of the most popular weight loss ingredients, this seems to be one of the safest. However, it’s not guaranteed to work well enough to really cause noticeable results. Reported adverse effects may include headache and urinary tract infections, although these are rare. Possible benefits include a mild increase in energy expenditure and fat oxidation.
Protein Foods: Foods high in protein like whey protein, grass-fed beef, wild-caught fish or free-range chicken require more energy for the body to break down than foods lower in protein. They’re also beneficial for reducing hunger or cravings and maintaining lean muscle mass, especially as you get older and naturally lose some every decade. If your goal is to lose weight, I recommend consuming half your body weight in grams of protein a day. For those seeking to burn fat and build muscle, aim to consume 0.7 to a gram per pound of body weight (for example, if you weigh 150 pounds, you should get 75 to 150 grams per day).
Green Tea: Green tea and green tea extracts have been shown to activate the body's thermogenic fat-burning activity. A study published in the American Journal of Clinical Nutrition found that men who ingested the active ingredient in green tea (catechins) significantly reduced their total fat area, waist circumference, skinfold thickness, and subcutaneous fat area.[2] As exercise physiologist Nick Coker explains in the article "Your Expert Guide to Green Tea," taking this ingredient with caffeine has been shown to make it even more effective.
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.
You may also know this root veggie as a sunchoke since they're the roots of a type of sunflower. According to a Canadian study, subjects whose diets were supplemented with a type of gut-healthy insoluble fiber called oligofructose not only lost weight but reported less hunger than those who received a placebo. Researchers discovered that the subjects who consumed the prebiotic fiber had higher levels of ghrelin—the hunger-suppressing hormone—and lower levels of blood sugar. And you guessed it: Jerusalem artichokes are one of the best sources of the fiber.

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.
You can acquire CLA from supplements as opposed to natural foods, but it might not be as beneficial, considering CLA found in supplements is not the most effective type for stopping fat storage. Whole foods are made of CLA isomers called c9, t11, while many supplements are high in the types of CLA called t10, c12, which have less drastic effects. Your best bet is to eat foods that supply relatively high doses: real butter from grass-fed cows (ideally organic), full-fat dairy (preferably raw and possibly fermented, such as yogurt), grass-fed beef, and to a lesser degree grass-fed lamb, veal, turkey and wild-caught seafood.
Instant Knockout contains green tea and cayenne pepper – both staples of many popular fat burners. These ingredients are said to help burn more calories, which could lead to faster results. IK also contains glucomannan, a fiber which may promote fullness and reduce food cravings. These ingredients are joined by vitamin B6 and B12, GTF chromium, zinc, piperine and green coffee extract. The result? A natural supplement without any risky substances – and one that could help you achieve your goals faster.

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.
Caffeine tolerance is lower – In the past fat burners with high stimulants made women feel worse not better. Now, the best female fat burners use natural alternatives to help you burn more calories. This means you can give your metabolic rate the boost it needs, improving your energy levels in the gym and avoiding problematic palpitations or nausea which can halt your progress.
There are several ways that grapefruit essential oil may act like a natural weight loss booster. Grapefruit’s active ingredients may be able to boost metabolism, reduce your appetite, lower cravings and give you a mild dose of uplifting energy. Enzymes found in the fruit help your body break down sugar according to certain study findings, and as an added benefit many people find the scent of citrus fruits reduces cravings for sweets. (8)

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.

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.
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.
When you make the decision to lose a few pounds or carve a couple inches off your waist, there are tons of different paths that you can take to get to your goal. Of course, exercise and a proper diet are a critical part of any fitness plan. But supplements can also be a great way to aid in your weight loss journey, and about 15 percent of adults have used them at one point in time or another to help them lose weight.
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.

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.
