A scoop of guacamole is one of the most effective fat-burning, hunger-squashing snacks known to man. Not only are avocados rich in vitamin B6—which directly counteracts the belly-fat-building stress hormone, cortisol—they're also full of monounsaturated fat. This healthy fat may actually prevent body fat distribution around the belly by down-regulating the expression of certain fat genes, according to research in the journal Diabetes Care. These same satiating fats may also be the reason behind another study that found people who ate half a fresh avocado with lunch reported a 40 percent decreased desire to eat for hours afterward.
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.
Are the weight loss claims about these ingredients necessarily true? It seems to depend on the type of thermogenic fat burners in question, the active ingredients that are used in the products, dosages taken and an individual person’s response. Active ingredients that are commonly used in thermogenic supplements vary by brand but usually contain a mix of stimulants, herbs and acids. Testimonials, along with findings from certain studies, suggest that thermogenics do seem to work for some — however in some cases their ingredients can also be dangerous or totally ineffective.
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.

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!


Adding a fat-burning supplement to your regimen to help burn belly fat won't necessarily be detrimental, but it's unlikely to do much good, either. You should always check with your doctor before you start taking a new supplement 1. According to personal trainer Christian Finn, the best ways for men to burn fat fast are to eat less than they burn, lift weights two to three times per week, eat a protein-rich diet and add in some cardiovascular work.


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.
Bad breath is but a small price to pay for reaching your body goals, right? According to a recent Japanese study, when rats were put on a high-fat diet, the animals that were also given a garlic compound gained less weight than their peers. Experts attribute the fat-fighting benefits to a powerful compound in garlic called allicin. (It also happens to be the same compound that gives garlic its pungent taste and smell.)
More than two-thirds of the adults in the United States are considered to be overweight or obese. Not only can carrying around extra weight affect your confidence and image, it can also play a major role in your health as well. Having too much body fat significantly increases your risk for a number of different diseases. These can include diabetes, cancer, cardiovascular issues, arthritis, and many more.

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.


Start at a low dose: Fat burners are designed specifically to give you the proper doses of various ingredients to support fat loss. But that doesn't mean that the more of the ingredients you take, the more results you'll see. Supplement manufacturers state the serving guidelines and directions so you can have a way of measuring what dose works best for you.
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.
Spicy Foods like Cayenne Pepper: Spices that warm the body seem to be good for more than just keeping you feeling toasty — they may also increase your body’s ability to burn fat, suppress hunger levels, normalize glucose levels and reduce your appetite for sweets. Studies have shown that herbs like cayenne pepper, turmeric, cinnamon and dandelion may all help reduce weight gain without having negative effects. (10) Because spices have positive effects on metabolism, I recommend adding some daily to things like homemade detox drinks, marinades for proteins, stir-fry, veggies or soups.

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…
Instant Knockout looks great – but all the signs suggest it offers much more than pretty packaging.

No proprietary blends and transparent formula are big bonuses and make this product stand out on our list!
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.

Hi, I am 45, 5’4, 200lbs. It floors people when I tell them my weight. I get that “oh you hide it so well.” Since November of 2017, I have cut out bread (once week i may have a serving of multi-grain bread), white potatoes, sugar (I do use honey to sweeten my coffee and drink at least 100oz water a day. I am a nurse, and work long hours. I have been trying to add some exercise into my diet. Since Nov I have not lost any weight. To say I am getting discouraged is an understatement. I know that it’s harder after a certain age, but my mom and I started the same thing and she lost 25lbs, and she is retired and doesn’t workout. What’s wrong with my body? Is there something you can recommend.

You say tomato, I say 9-oxo-ODA. That's the name of a compound found in the brilliant red fruits that Japanese researchers recently discovered can effectively activate your DNA to burn more fat. Tomatoes are also brimming in beta-carotene and lycopene, two potent antioxidants that mop up harmful compounds that promote fat storage. One Journal of Nutrition study found people whose diets contained the most beta-carotene and lycopene had the smallest waists and the least belly fat. And at only 5 calories apiece, grab a few sun-dried tomatoes! Cooked tomatoes contain more bioavailable lycopene than raw tomatoes, according to Cornell University researchers.


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.
One of the reasons your metabolism isn't burning away fat as efficiently as you'd like? Look to your magnesium levels. This essential micronutrient is required for the body to produce and store energy, and also helps boost lipolysis (a process by which your body releases fat from its stores to use as energy)—yet 75 percent of Americans do not get their RDA of this important metabolism-boosting mineral. Just a half cup of pumpkin seeds provides nearly 100 percent of your daily magnesium needs.
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.
Many television ads are now pitching devices that supposedly stimulate muscles to contract repeatedly without exercise. I even saw an infomercial for an "ab belt" that claimed it does the work of 700 sit-ups in 10 minutes! The ad shows people doing various abdominal exercises the wrong way, hating every second of it, versus smiling men and women going about their days with "Ab-whatevers" strapped around them. How enticing!

CLA: Conjugated linoleic acid, or CLA, is a naturally occurring fatty acid, similar to an omega-6 fatty acid. Even though CLA is a fat, studies show that consuming 1.4-3.0 grams per day can lead to overall body-fat loss.[3,4] It can also help you retain muscle during periods of weight loss, as kinesiologist Ciaran Fairman, Ph.D., explains in the article "Your Expert Guide to CLA." Remember, muscle is your ally for long-term success!

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.

LeanBean is focused on suppressing your appetite with the konjac root extract. It also contains glucomannan as a key ingredient. As stated earlier on in this review, this is highly popular ingredient and is one to look for in these supplements. It also includes garcinia cambogia which is a tropical fruit also known as the Malabar tamarind. It also contains green coffee (unroasted coffee beans) which are rich in healthy antioxidants. LeanBean has other common energy boosting ingredients like cayenne pepper and black pepper extract (piperine).

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.
