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)
So, what is a fat burner? As explained in the journal Obesity Reviews, 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."[1] However, that's a wide range of functions, and in pill form especially, it can mean a lot of things! So, let's dig a little deeper.
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)
Fat burners have ingredients, such as caffeine and green tea, that act as a hunger suppressant. These help to ward off those cravings and decrease your overall hunger. Your body produces a hormone called leptin that is responsible for telling your body it is full and doesn’t need more food. This helps reduce the urge to overeat or snack throughout the day.
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.
The leafy green is jam-packed with energy-boosting nutrients such as vitamin A, iron, and folate. It can also reduce your appetite—helping to curb your calorie intake and encourage your body to start burning fat—thanks to natural compounds called thylakoids. Swedish researchers found that over three months, women who consumed a five-gram thylakoid supplement from spinach reported a 25 percent reduction in hunger and cravings and significantly more weight loss (11 pounds) than the control group!
You've heard of fat burners, those pills that can make fat melt off your body like ice cream on a hot summer day, right? Well, sorry to burst your bubble, but even the best fat burners aren't magic. They're just supplements. That means that even though they're designed with ingredients that can really give you an extra boost to help burn fat, they can't replace a solid diet and exercise plan.
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.
This naturally sweet winter squash boasts one of the highest fiber counts of all the veggies, ringing in at a whopping 9 grams per cup. Promoting feelings of fullness—and thus staving off overeating so you can burn, rather than gain, fat—with satiating fiber isn't the only way you'll target that turkey neck. That's because acorn squash is also an excellent source of vitamin C, a micronutrient that your body uses to decrease levels of the fat-storing hormone cortisol and boost the fat-burning effects of exercise, according to Arizona State University researchers.
The amount of a fat burner supplement that you should take depends based on what ingredients are in your supplement. It is generally best to follow the instructions on the label so that you are not taking too much each day. It is often good practice to start off at the lower range of the suggested dose, especially at the beginning. This will allow you to make sure your body responds well to the supplement.
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)

Probiotics are “good bacteria” found in fermented foods or drinks, and also supplements. These bacteria reside in your gastrointestinal tract (also called the microbiome) and have many functions throughout your body. Research suggests that probiotics have numerous benefits for immune, digestive, hormonal and central nervous system functions. Studies have indicated that there are differences in the microbial composition between obese and non-obese patients, and probiotics are involved in energy homeostasis, regulation of appetite, dietary intake and storage of lipids (fats).


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.

It’s important to do full-body strength training if you want to lose belly fat—especially if you’re trying to keep it off for the long haul. “Strength training should be a part of just about everybody’s exercise plan,” says Dr. Cheskin. That’s because strength training helps you build muscle, which will replace body fat. And because muscle is metabolically active, you'll continue to burn calories after working out, thereby, reducing overall body fat. Bonus: When your metabolic rate becomes faster due to muscle growth, you’ll have a little more wiggle room in your diet if that’s something you struggle with, says Dr. Cheskin. 

Guarana: Guarana has among the highest concentrations of caffeine in any plant; it contain up to 3.5 percent to 5.8 percent caffeine by volume, while coffee only has up to 2 percent. For increased energy and enhanced mental focus, some people use between 200 to 800 milligrams of guarana a day, which seems to be generally safe. However, side effects for some can include those similar to consuming too caffeine, such as difficulty sleeping, indigestion, anxiety, changes in blood pressure, dependence and a quickened heartbeat. Guarana can also interact with medicines like some antidepressants, lithium, sedatives, other stimulants and blood thinners.
Who knew there was a connection between a spicy pepper scorching your mouth and burning your belly fat? Scientists did! According to a study in the American Journal of Clinical Nutrition, daily consumption of one of the compounds found in pepper (capsaicin) speeds up abdominal fat loss by boosting the body's ability to convert food into energy. It also acts as a natural appetite suppressant: men who ate spicy appetizers consumed 200 fewer calories at later meals than those that did not, a study by Canadian researchers found. All you have to do to reap the benefits is use a pinch of cayenne pepper to season grilled fish, meats, and eggs.

Performance Lab Sport contains several quality ingredients including coleus forskohlii, cayenne pepper extract, black pepper extract and the ‘featured nutrient’ beta-hydroxy beta-methylbutyrate (HMB). HMB is purported to neutralize enzymes that cause muscle damage when in the gym, boost hypertrophy and improve strength gains. All combined, these ingredients could help you acheive your training goals. Though you need to make sure you’re exercising regularly or eating well, as no supplement is a remedy for a bad diet and inactivity.

Hourglass contains a great ingredient portfolio, enough to easily compete with many of the market leading fat burners. For instance, you’ll find glucomannan, a root extract that sits undigested in your stomach for a while to stop you from getting annoying hunger cravings between meals (and of course to stop you snacking). It contains green tea extract and black pepper extract (bioperine) which are found in many fat burners. It also contains a range of vitamins including Vitamin B6, Vitamin B12 and Vitamin D3.

Brand reputation – have you heard of the brand/company who makes the product? Are they reputable, and known for making quality products? In our list (found above), we only included products from quality companies – but there are certainly low quality products out there. Especially if you’re doing your own research, read through some reviews to determine the quality of the product and the company behind it.

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.
