One 2009 report published in the Journal of Nutritional Biochemistry found that CLA has positive effects on energy metabolism, adipogenesis, inflammation, lipid metabolism and apoptosis. (6) A 2007 study published in the British Journal of Nutrition similarly found that supplementation of a CLA mixture in overweight and obese people (three to four grams a day for 24 weeks) decreased body fat mass and increased lean body mass. (7) And regarding CLA’s safety, there seems to be very little risk for adverse effects on overall blood lipids, inflammation levels and insulin response in healthy, overweight or obese adults.

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.
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).
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.
Supplements are able to control your fat absorption in two main ways. First, ingredients like orlistat work by disabling the enzyme that is responsible for digesting and breaking down fat. If this enzyme doesn’t work, much less fat is absorbed into the bloodstream. Second, substances like chitosan work by attracting the fat molecules from the food you eat. They hold onto the fat throughout the digestive process until they are excreted from the body.
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.
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.

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)
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!
After your diet, and once you cycle off of your fat burner, it's important to bump your calories back up to or above what is known as "maintenance," where your calories and calorie burn are roughly equal. One popular way to do this is what is known as a "reverse diet," where you gradually and systematically raise calories. Registered dietician Katie Coles explains how in her article "The Ultimate Guide to Reverse Dieting."
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)
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.
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…
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.

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.
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.
Some cheat meals are better than others. And a high-carbohydrate, moderate-protein meal, however "naughty," can help you stay on track. The reason: Carbohydrates have the greatest influence on leptin levels, which help you burn fat and feel satisfied. And protein has the greatest influence on satiety because of its influence on appetite-regulating hormones and high thermic effect—the process of digesting protein requires more energy of your body than any other macronutrient. So, go ahead and grab a bowl of spaghetti and meatballs. Contrary to popular belief, pasta is actually a fairly low-glycemic food, meaning it won't drastically spike your blood sugar levels.

From all of our research TLabs Fat Burner been ranked very highly and received well by users. It is designed to be the most “Transparent” fat burner formula on the market, as it comes from the rapidly growing product suite from Transparent Labs. Known for their “open formulas”. When combined with proper nutrition and exercise it can help you reach some of your weight loss goals. Also, just in case you’re intolerant to stimulants, Transparent Labs also offers an awesome stimulant-free fat burner as well!

This substance is also a great way to increase your energy levels and focus. Caffeine is associated with few side effects, and it is highly effective and found in most fat-burners. It is important to note that caffeine can cause addiction, and your body can build up a tolerance to it. If this occurs, it will start to feel less effective. It is important to not continue increasing doses to counteract this effect, as it can cause organ damage or other health issues.
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.
Most weight loss supplements are not tested in clinical trials or included in evaluation studies conducted under well-controlled conditions with average human volunteers. Weight loss pill manufacturers are not required to test new ingredients or even to list things like potential side effects on the product’s label. Therefore it can be hard to tell what type of ingredients you’re even ingesting when consuming weight loss supplements or how you’ll react to different dosages.

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.

LeanBean is the self-described supplement ‘exclusively formulated for women’. Said to ‘harness the power of nature’ to complement your healthy lifestyle. As is common with this type of supplement, the effects on men and women are theoretically the same, so you can both use it. The LeanBean formula contains 12 ingredients and we’ve rounded them up for you to see how well researched and developed it really is.
For women, high levels of body fat can lead to pregnancy problems. The babies of overweight mothers are more likely to be stillborn, born early, and even have brain defects. These women are also at a higher risk of developing diabetes during their pregnancy or having preeclampsia (high blood pressure), which can negatively affect both the baby and mother. Their children are also at a higher risk of being overweight or obese themselves.

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.
A longtime enemy of doctors and dieters, pork has been coming around as a healthier alternative of late–as long as you choose the right cut. Your best bet is pork tenderloin. A three-ounce serving of pork tenderloin has slightly less fat than a skinless chicken breast; It has 24 grams of protein per serving and 83 milligrams of choline. In a study published in the journal Nutrients, scientists asked 144 overweight people to eat a diet rich in fresh lean pork. After three months, the group saw a significant reduction in waist size, BMI and belly fat, with no reduction in muscle mass! They speculate that the amino acid profile of pork protein may contribute to greater fat burning.
Caffeine: Studies show possible modest effects on body weight or decreased weight gain over time when consuming caffeine. Caffeine is usually OK in small to moderate amounts for most people but can also cause side effects like heart palpitations and restlessness. There’s no sound evidence that caffeine alone will help you lose weight, and the cons of taking too much caffeine definitely seem to outweigh the pros.

It's a dietary miracle: A fat that makes you skinny. Dietary supplementation of coconut oil actually reduced abdominal obesity in a study published in the journal Lipids. Of the participants, half were given two tablespoons of coconut oil daily and the other half were given soybean oil, and although both groups experienced overall weight loss, only the coconut oil group saw smaller waistlines. And other researchers have also pointed to the waist-whittling effects of the tropical oil. In a separate study of 30 men, those who ate 2 tablespoons of coconut oil a day shrank their waists by an average of 1.1 inches in one month. Thank C.O.'s medium-chain triglycerides, which are burned as energy instead of being stored as fat, and lauric acid, which has been shown to pinpoint belly fat and torch it.

That said, despite what you may think, weighing yourself more often doesn't automatically lead to better weight-loss results, as Paul Salter explains in the article "How Often Should I Weigh Myself?" Your weight is only one part of the story—not the whole story—so don't fixate too heavily on it. How you feel, how you look, and how your workouts are progressing are also crucially important!

One of the best ways to get the benefits of green tea is to consume matcha green tea, a concentrated powdered green tea from Japan that seems to have some noteworthy fat-burning benefits. What’s in matcha that makes it so beneficial for everything from cognitive function to enhancing fat-burning? It’s the catechins, a type of antioxidant found in high levels in green tea that may reduce body weight, speed up recovery following workouts and decrease free radical damage.

Instead of satisfying your sweet tooth with some refined sugar, turn to berries and enjoy a slimmer waistline in no time without exercise. Berries are loaded with antioxidants, which can help reduce inflammation throughout the body, and research from the University of Michigan reveals that rats given a cherry-rich diet shaved off a significant proportion of their belly fat when compared to a control group. Berries like strawberries, raspberries, blueberries, and blackberries are also loaded with resveratrol, an antioxidant pigment that has been linked to reductions in belly fat and a reduced risk of dementia, to boot.


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.
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.
While it's often assumed that bread is off-limits when you're trying to lose belly fat, the right bread may actually expedite the process. Switching to sprouted bread can help out carb-lovers eager to get their fix without going up a belt size, thanks to the inulin content of sprouted grains. The results of a study published in Nutrition & Metabolism reveal that found that pre-diabetic study subjects whose diets were supplemented with inulin shaved off more belly fat and total weight than those whose meal plans didn't pack this healthy prebiotic fiber.

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.
One thing a fat burner won't do, however, is fix a broken diet. If you're eating for healthy fat loss, the way Krissy Kendall, Ph.D., explains in the comprehensive guide "How to Lose Weight," then a thermogenic fat burner can help with the other stuff: boosting energy, helping to curb appetite, promoting fat to be used for energy, and even increasing your metabolism and core temperature—what is known as "thermogenesis"—so you burn more calories throughout the day.

Instant Knockout looks great – but all the signs suggest it offers much more than pretty packaging. The product can help support your training goals, boost confidence and keep you motivated for longer as part of a good diet and exercise routine. No proprietary blends and transparent formula are big bonuses and make this product stand out on our list!


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).
In fact, researchers at Wake Forest Baptist Medical Center found that every 10-gram daily increase in soluble fiber was associated with a 3.7 percent decrease in dangerous visceral fat over five years. Those who were active got even leaner, shaving off twice that much fat in the same amount of time. To start ditching that extra belly fat today, add the best high-fiber foods to your menu!

Stop treating your kitchen like an all-night diner and you'll stop seeing those unwanted pounds piling onto your frame, too. The results of a study published in Cell Metabolism found that mice who only had access to food during an eight-hour period stayed slim over the course of the study, while those who ate the same number of calories over a 16-hour period gained significantly more weight, particularly around their middle. When you're finished with dinner at night, shut the fridge and don't look back until morning — your belly will thank you. When you do head back to the kitchen in the A.M., make sure the best healthy kitchen staples for cooking are there waiting for you.
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.
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)
Surprised? Although olive oil contains fat, it actually contains a type of healthy fat that has been found to decrease levels of fat-storing inflammation. According to a review published in the International Journal of Molecular Sciences, a polyphenol only found in unrefined extra virgin olive oil—oleocanthal—reduces inflammation in a similar way that ibuprofen does: it prevents the production of two pro-inflammatory enzymes, COX-1 and COX-2.
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.

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.
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.)
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.
