For most people, belly fat is the hardest area on the body to lose weight. Belly fat is more stubborn than other areas of the body because stomach fat has different amounts and types of fat cells than the legs, arms, and face. No wonder so many people trying a new diet or exercise program notice thinning and toning in their faces and limbs first instead of their abdomen area.
Luckily, there are belly fat burners on the market that can help target your midsection for a slimmer waistline and flatter stomach. In addition to burning stubborn body fat, these supplements can also provide additional health benefits such as increased metabolism, more energy, and reduced hunger cravings.
But with so many fat burners on the market, choosing a high quality product that actually works is no easy task. Although some fat burning pills work amazing, others don’t have the right combination of ingredients to burn stomach fat.
We’ve tested and reviewed the best fat burners out there to help you find the right product for your weight loss goals. We evaluated each belly fat burner based on its ingredients, customer reviews, advertised benefits, price, and guarantee.
If you’re ready to burn belly fat, lose weight, and look the best you’ve had in years, here are the best stomach fat burning pills for 2021:
Top 5 Best Belly Fat Burners of 2021
1 – LeanBean: Top Belly Fat Burner For Women
LeanBean is the best fat burner supplement for women. Formulated for active women, LeanBean is a fat burner that contains vitamins, minerals, antioxidants and natural ingredients such as glucomannan. This is a water-soluble fiber extracted from the roots of the elephant yam, also called konjac, to help manage your appetite. Glucomannan has a long history as an ingredient in herbal mixtures and traditional foods in Southeast Asia, such as shirataki noodles.
How it works
The fiber from glucomannan might help you feel full longer, leading to fewer cravings. The manufacturer says LeanBean also contains zinc, vitamin B6, vitamin B12, chromium picolinate, and choline, which have been studied to support fat metabolism, the synthesis of carbohydrates, and reducing tiredness and fatigue.
Also, LeanBean contains green coffee beans, which are unroasted coffee beans (roasting turns them brown) that are naturally high in antioxidants. LeanBean recommends taking two pills with water three times per day, preferably with at least 8 ounces of water about 30 minutes before breakfast, lunch, and dinner.
Many fat burners contain caffeine and other stimulants, but too much caffeine can cause nausea or jitters. LeanBean’s fat burning formula includes vitamins, minerals, and caffeine alternatives such as turmeric and the amino acid L-carnitine fumarate, which helps the body produce energy, to provide a natural energy boost.
LeanBean also contains garcinia cambogia, a tropical fruit with hydroxycitric acid, which may block an enzyme your body uses to make fat. Garcinia cambogia also might increase your brain’s serotonin levels, so you feel less hungry. To further reduce hunger and binge eating, LeanBean contains chromium picolinate, which may increase the body’s response to insulin and lower blood sugar.
Here is the full list of ingredients inside of LeanBean:
Who Should Take LeanBean?
Women who want to lose belly fat and avoid the high stimulants of more aggressive fat burners may benefit from LeanBean, which is formulated with only trace amounts of caffeine (about ten times less than the average coffee cup). With a complementary diet and increased exercise levels, many users find LeanBean effective, which is why it’s our top choice pill to try to reduce fat levels.
2 – Instant Knockout: Best Fat Burner For Men
Instant Knockout is the one of the best fat burner supplements for men. Pro boxers and MMA fighters need to burn fat in time for a fight. The manufacturers of Instant Knockout considered this when they developed their pill formula for these athletes. They soon found it so successful in burning belly fat that they released it to the public.
Instant Knockout is our pick for the best fat burner for men because it contains 10 fat-burning heavyweights, such as green tea extract and cayenne pepper. Plus, pros such as MMA coach Greg Jackson and MMA fighter Diego Sanchez (middleweight champion of The Ultimate Fighter Season 1) endorse it.
How it works
The fat burners in each Instant Knockout pill work together to ramp up your metabolism, so you store less fat. With a faster metabolism, you’ll also burn more stored fat to use as energy. Other ingredients keep you energized and reduce your hunger pangs so that you won’t reach for snacks between meals. The manufacturer recommends taking Instant Knockout four times a day along with your regular diet and exercise routine for the best results.
Instant Knockout contains green tea, which scientific studies show may elevate your metabolic rate and burn calories through thermogenesis. This process dissipates energy by generating heat in specialized tissues such as skeletal muscle. Other ingredients, such as capsaicin, increase the amount of energy you expend and raise your metabolism.
With any supplement, absorption is important, so Instant Knockout contains piperine, which aids in digestion, and GTF chromium, a yeast-bound form of chromium that might increase how the body regulates glucose. Instant Knockout also contains glucomannan, a natural fiber to reduce cravings.
Here is the full ingredient list inside of Instant Knockout:
Who should take Instant Knockout?
Instant Knockout isn’t strictly a men’s only formula – the manufacturer says women who want defined curves might like it, too. But because athletes endorse it, we think it’s best for people looking to lose weight and shed body fat while building muscle.
3 – PhenQ: Natural Thermogenic Supplement For Weight Loss
PhenQ is the most effective weight loss pill for women over 40. PhenQ calls itself the “ultimate, all-in-one weight-loss pill.” It contains a trademarked formula called α-Lacys Reset® that accelerates metabolism through thermogenesis, firing up your body’s ability to burn calories. Combining ingredients helps users lose weight, burn belly fat, and increase muscle, the manufacturer says.
How it works
The manufacturer says that PhenQ contains ingredients that make cutting calories easy by curbing your appetite. Other ingredients stop your body from producing new fat while you burn off fat. Also, this supplement has “mood-enhancing properties” to avoid feeling cranky and deprived.
PhenQ contains Capsimax powder, a blend of capsicum (peppers), piperine, caffeine, and niacin (a B vitamin), which may turn up your body’s energy, activating fat burning. This fat burner also contains fiber from the nopal cactus, which is rich in amino acids and might help weight loss caused by retaining fluids. To combat the tiredness dieters sometimes feel, PhenQ includes L-carnitine fumarate, an amino acid and energy-booster naturally found in red meat, green vegetables, and nuts.
Here’s the full list of ingredients inside of PhenQ:
Who should take PhenQ?
Although PhenQ can work for men as well as women, we recommend it for women over 40. Women aged 40 and older find losing weight more of an uphill battle because of menopause and other hormones, metabolism, and body composition changes.
4 – Trimtone: Effective Fat Burner That Works Fast
TrimTone is the best fat burning pill for appetite suppression. Trimtone has a one-a-day formula designed to curb cravings that may help people lose weight by hitting their calorie goals. It contains a combination of glucomannan so that you feel fuller faster and longer, plus fat burners such as green tea and caffeine.
How it works
The ingredients in Trimtone stimulate your body’s thermogenesis, converting fat into energy and boosting your metabolism. The added fiber from glucomannan also suppresses your appetite to help people stay in control of their eating habits. It’s also formulated to work in one dose. The manufacturer says to take one pill per day with water before breakfast.
Trimtone contains 100 mg of caffeine, which acts as a stimulant and a fat burner, plus it breaks down stored fat. It also includes green coffee bean extract, which studies show also improves metabolism and might reduce the amount of fat and glucose absorbed from foods. Green tea and grains of paradise (a plant from the ginger family) round out the fat-burning ingredients.
Here is a list of ingredients inside of TrimTone:
Who should take TrimTone?
People who have struggled to lose weight because they don’t feel satiated after eating might benefit from the added fiber and fat-burning ingredients of Trimtone. Plus, if you’re concerned about forgetting a dose of fat burner throughout the day, its one-pill formula removes that worry.
5 – PrimeShred: Men’s Tummy Fat Burner For Building Muscle
PrimeShred is the best weight loss supplement for men looking to build muscle while burning fat. PrimeShred combines powerful thermogenic ingredients meant to stimulate the metabolism, burn fat throughout the body, fuel your energy levels and hone your focus so your body can keep up with demanding workouts. Dieting and intense exercise routines can leave you feeling drained, the manufacturer says. The brain-boosting compounds in PrimeShred, such as rhodiola rosea root, may help counteract that brain fog.
How it works
In addition to caffeine, green tea, and the capsaicin in cayenne pepper, PrimeShred also contains amino acids such as L-tyrosine, which works with the other compounds to tackle fats, and L-theanine, which works to reduce triglycerides, a form of stored fat. The manufacturer says you’ll see the most effective results when you take three pills about 20 minutes before breakfast on both training and non-training days.
PrimeShred contains several B vitamins to help convert calories from food into energy faster. To enhance your workouts, it contains rhodiola rosea root, also known as arctic root or golden root, which people in cold regions of Europe and Asia have used to adapt to stress and alleviate fatigue.
PrimeShred contains a boost of DMAE, a compound naturally produced in the body that regulates brain function. You can find DMAE naturally in fatty fish such as anchovies, salmon, and sardines.
PrimeShred’s compounds also balance each other. For instance, the amino acid L-theanine, found in green tea, smooths out the edge that some people might feel after ingesting caffeine. Bioperine, a patented extract from black pepper, is thought to enhance digestion and how well the body transports and absorbs various nutrients.
Here’s the full list of ingredients inside of PrimeShred.
Who should take PrimeShred?
PrimeShred is for any man that wants to shred fat without losing muscle mass or energy. It’s also vegan-friendly and free of artificial ingredients, which any health-conscious man will appreciate.
Health Benefits of Taking Natural Fat Burners
Studies have proven that fat burning ingredients such as caffeine, green tea extract (a concentrated form of green tea), protein powder, and soluble fiber have helped people lose weight with few side effects. For instance, Healthline cites several studies noting that a high-protein diet helps your body preserve muscle mass, boost your metabolism, and curb your appetite, leading to weight loss.
When you take weight loss pills, you reap all the benefits from these compounds in a convenient form, such as a pill or a powder. If you don’t like the taste of plain coffee or tea, or you have trouble adding extra protein to your plate, a fat burner supplement is an easier way to tap into their benefits. Here are a few:
Anyone who reaches for that morning cup of coffee can attest to the energy jolt from caffeine. Cocoa beans, green tea, and coffee all contain this substance, a popular ingredient in fat-burning supplements. Coffee also contains chlorogenic acid, a compound that research suggests may help lower blood sugar and improve mood. Besides fat burning pills and coffees, you can also find chlorogenic acid in foods such as apples, pears, tomatoes, eggplant, strawberries, and blueberries.
Another benefit of adding a supplement for burning fat to your regular diet and exercise routine is enhanced weight loss. Coping with unwanted weight gain and reaching your ideal body weight can be a struggle, but the ingredients in these supplements may provide additional support. For instance, green tea extract contains the polyphenol epigallocatechin gallate, a compound that might help burn fat through thermogenesis, the body’s burning of calories to produce heat.
When you’re more energized, you’re naturally more alert and focused, another reason lots of people reach for a caffeinated beverage such as coffee or soda to perk up later in the day. A fat burner supplement may improve your focus without the added sugar or other ingredients in many sodas.
Both protein and fiber help curb your appetite by helping you feel full, reducing levels of hunger hormones such as ghrelin. While you can eat many protein-rich and fiber-rich foods, a supplement is a way to increase your protein or fiber intake with fewer calories.
Research shows that caffeine can temporarily boost your metabolism over one to two hours. Combined with exercise and fat-burning foods, you might ramp up a sluggish metabolism with the help of a natural supplement such as fat burning pills.
Types of Fat Burning Supplements
Fat burners are designed to tackle weight gain and help you lose excess fat in a few different ways. Here’s a short overview of the different types of fat-burning supplements on the market.
Thermogenic Fat Burners
These enhance how the body produces heat from metabolic processes. The more body heat that you produce, the more belly fat you’ll use and burn, leading to weight loss.
We need food to fuel our bodies, but we often eat for other reasons, such as boredom. An appetite suppressant contains ingredients that might help you from overeating by helping you feel fuller for longer.
Carb blockers inhibit some of the enzymes that the body uses to digest the complex carbs found in pasta, rice, bread, and starchy vegetables such as potatoes. Anything undigested passes into the large intestine without being absorbed as calories or into your blood sugar.
Similar to carb blockers, fat blockers inhibit some fats from being absorbed and generating additional body fat. Some fat blockers also prevent the stress hormone cortisol from storing visceral fat, adding to weight loss.
Factors To Consider Before Buying Belly Fat Burner Pills
So many fat burners on the market claim to help with weight loss and leave users with a toned figure. The U.S. Food and Drug Administration is not authorized to review dietary supplements for effectiveness and safety before they’re marketed to the public. While this can open the door to unwanted side effects, this crowded market also makes choosing a fat burner confusing. Before you decide which weight loss supplements to buy, here are some important considerations:
Clinically Dosed Ingredients: Researchers have studied some natural compounds such as caffeine, fiber, and green tea extract repeatedly, leading them to recommend these compounds for their weight loss benefits. A thermogenic fat burner should list the amount of each ingredient on the label.
Stimulant or Non-Stimulant? Caffeine is a stimulant, but consuming it too often might make your body tolerate it better, reducing its effectiveness, some studies show. If you already have several caffeinated drinks to get through the day, you may not want to ingest more caffeine through a supplement. You also may want to research a fat burner that doesn’t contain a stimulant.
Price: Fat burners are a maintenance product. While you don’t take them as long as a daily vitamin, you do take them for a while — until you reach your ideal weight and then as needed afterward. Although some manufacturers offer sales and deals, such as getting a free bottle with the purchase of two, fat burners vary in price, from as low as $10 a month to as high as $70 a month. So you’ll want to check which ones fit best into your budget.
Number of Servings in a Bottle: Notice how many pills or capsules are considered a serving. One bottle of a fat burner may contain 120 capsules, but if the instructions are to take those four times a day, the bottle will be empty after one month.
Money-Back Guarantee: Because a fat burner complements your regular diet and exercise routine, some people might not see results right away. That’s why we like manufacturers that offer a money-back guarantee if you’re dissatisfied or have trouble with side effects. PhenQ, for instance, offers a 60-day money-back guarantee, granting users two months to notice results.
Things To Avoid When Choosing a Belly Fat Burner
When you’re dealing with unexpected or stubborn weight gain, you might find it tough to resist claims that certain fat burners make as far as targeting fat cells and giving you the body you’ve always imagined. But those claims can be a lot of smoke without any substance. As you research different weight loss products, make sure to watch for the following:
Aggressive Marketing Tactics: It’s one thing to share testimonials from people who have been satisfied with a supplement or quote from athletes or celebrities who endorse it. It’s another to heighten your sense of fear or urgency through marketing to make you think you’re missing out on something that these other people have.
Proprietary Formulas: In the interest of generating curiosity, some fat burners have proprietary formulas with secret ingredients. Make sure that you know what’s inside these products by checking the label. All ingredients should be listed, even if they’re combined into a manufacturer’s formula, to avoid risky side effects with any other supplements or medications that you’re taking.
Too Many Stimulants: Coffee, coffee beans, tea, caffeine, and chlorogenic acid all are natural stimulants. While they don’t raise the heart rate or your body’s energy in the same ways, too many stimulants can cause unpleasant side effects, especially if you’re taking other supplements or prescription medication for a chronic condition. For instance, too much caffeine can cause side effects, including irregular heartbeat, seizures, headaches, diarrhea, insomnia, irritability, and possible hormonal imbalances.
How To Get The Most Out of Weight Loss Supplements
Weight gain doesn’t happen overnight. Neither does weight loss. No matter how quickly we want unwanted fat to disappear, there’s no magic elixir that makes fat vanish within a few days or a week. The manufacturers of the best weight loss supplements we’ve recommended all say that you won’t see results just by taking these pills.
You need to incorporate them into your regular diet and fitness routine. Consider them part of your weight loss support system, helping you fight weight gain by making it a little easier to control your appetite, monitor your calorie intake, and burn more energy.
Are Fat Burning Supplements Safe For Weight Loss?
Because the manufacturers we recommend all cite studies involving the health benefits of the natural ingredients they use, we’d say that they are safe overall for weight loss. However, one ten-year study published in the New England Journal of Medicine found that the adverse side effects of supplements were responsible for an average of about 23,000 emergency department visits per year.
That’s why it’s important to know the side effects of other supplements or medications that you’re taking and what your allergies and sensitivities are. For instance, if you avoid caffeinated drinks because of high blood pressure or how it affects your heart rate, you will want to avoid a fat-burning supplement that contains caffeine or similar stimulants.
Who Should Use Fat Loss Pills?
If you’re struggling with weight loss through diet and exercise alone, a fat loss pill might be just the boost your body needs to help you achieve the results that you want. Be sure, however, to read through all the information that manufacturers provide about the ingredients in their products and the testimonials about how effective they are, as well as the side effects. That way, you can choose which product is right for you.
Final Thoughts – Are Thermogenic Fat Burners Right For You?
Between fitting exercise into a busy day, tracking your calorie intake, and trying to eat a healthy diet, losing weight can be a challenge for many people. But testimonials from people who previously had trouble with weight loss say that thermogenic fat burners helped them lose weight and build the body they wanted. These products just may work for you, too.
