5 Best Fat Burner Supplements of 2021

#1 LeanBean: Best Fat Burner for Women

leanbnean

LeanBean is our choice as the best overall fat burner for women. LeanBean takes a different approach to fat burning and weight loss. Instead of hopping you up on caffeine and synthetic chemicals to trick your body into temporarily losing weight, this thermogenic fat burner takes a three-pronged approach to help you lose weight naturally and develop the healthy habits to keep it off.

By battling food cravings, increasing metabolism, and boosting your energy levels, the LeanBean formula gives you the tools you need to kick sugar to the curb and have the willpower and energy to hit the gym. Instead of feeling like you’re on a never-ending hamster wheel, LeanBean gives you some extra help in the metabolism area, too. 

LeanBean boasts a list of all-natural ingredients to burn excess fat and tone your tummy, thighs, and butt.

Glucomannan: This ingredient is key in helping you control food cravings and calorie intake. This fat burner works to suppress your appetite by swelling your stomach (without bloating). The concentration of glucomannan is higher than most other brands, coming in at 3 grams for a daily dose. 

Choline: This nutrient is vital for several bodily functions, including memory, heart health, and metabolism. It can aid in weight loss by helping the body utilize and burn fat.

Vitamin B6 and B12: B vitamins are a natural energy source, helping you battle both mental and muscle fatigue to get closer to your weight loss goals. B vitamins also help regulate metabolism.

Chromium Picolinate: A common ingredient in fat burner supplements, chromium picolinate is like willpower in a bottle. This compound keeps blood glucose levels in check, which can drastically reduce sugar cravings and promote fat loss. 

Green Coffee: Unroasted coffee beans are green, and they’re also better for you. These coffee beans are rich in antioxidants, and more than one study has shown that this coffee bean extract can potentially have a positive effect on your body composition. There is a small amount of caffeine. 

Turmeric: You’ll see this powerhouse ingredient in many fat burner supplements, but LeanBean uses just the right amount for female athletes. 

Garcinia Cambogia Extract: Dr. Oz has been talking about this tropical fruit for more than a decade as a magical solution for any weight loss program. The bottom line is that it works by helping you feel fuller and more satisfied after eating.

Piperine: Black pepper extract has a couple of functions in the LeanBean formula. First, it helps the body absorb all the nutritional goodness. Second, it acts as a natural thermogenic, heating the body from the inside out and boosting metabolism.

The recommended dosage for Leanbean is two capsules three times per day for a total of six capsules daily. Each dose should be taken before a meal and with an eight-ounce glass of water to aid absorption.

LeanBean is an ideal fat burner supplement for women. And yes, we’re all equal, but that doesn’t mean that men and women don’t have some differences when it comes to a weight loss supplement. Sometimes it seems like all a guy has to do is cut out soda, and the pounds melt off while a woman has to do ten times more work to get the scale to budge an ounce.

#2 PhenQ: Best Belly Fat Burner

phenq

PhenQ is our top choice for the best belly fat burner supplement. Have you ever noticed that belly fat tends to hang around long after you’ve slimmed and tones your arms and legs?

Thanks to human biology, we’ve evolved to use the abdominal area as a store of fat when food is scarce. Unfortunately, it isn’t easy to convince our bodies that a supermarket full of food is right around the corner, so it doesn’t need to hang onto every morsel we swallow.

PhenQ helps dissolve belly fat by solving the top five problems most dieters face:

  1. Suppresses appetite
  2. Burns excess fats
  3. Increases fat oxidation
  4. Boosts energy levels
  5. Improves mood

By addressing the five different saboteurs in the average person’s weight loss journey, it’s no wonder that PhenQ made it onto our list of top fat burner supplements.

Ingredients

Capsimax Powder: This proprietary blend combines capsicum, caffeine, piperine, and niacin. Together, these ingredients form a powerful thermogenic, which boosts the body’s internal heat production and increases the rate at which the body metabolizes fat. Capsicum alone can result in dramatic weight loss, and when combined with these other compounds, PhenQ is a recipe for success.

Chromium Picolinate: Hunger cravings can sabotage any diet, so PhenQ contains chromium picolinate to control blood sugar levels. This results in a decrease in the desire to eat sugar and carbs.

Caffeine: This natural energy source isn’t just for your daily cup of joe. Coffee bean extract is also a natural thermogenic that can contribute to weight loss.

Nopal: Also known as cactus, this spiky plant contains a form of fiber that helps you maintain that feeling of fullness longer. It also contains an energy-producing amino acid and a natural system for preventing water retention. 

Because fat in the mid-section can be the toughest to lose, it requires a powerhouse fat burner supplement. If your tummy is flat and you’re battling the bulge in other areas, you can skip PhenQ and try another diet supplement on our list. But, if you’re trying to blast belly fat, PhenQ is one of the best weight loss pills out there.

  • Best fat burner for belly fat

  • Improves mood and energy levels

#3 Instant Knockout: Top Thermogenic Fat Burner for Men

instant knockout

Instant Knockout is the top thermogenic fat burning supplement for men. Developed specifically for pro boxers and MMA fighters, Instant Knockout lives up to its name of knocking out fat… fast! Say goodbye to beer guts and man boobs as you wipe the floor with your fat.

You don’t have to be an elite to benefit from Instant Knockout’s formula, though. This fat burner supplement is designed for anyone that wants to shed weight without feeling hungry or tired. Thanks to a powerful combination of ingredients (including caffeine from green tea extract) that boost metabolic function, enhance energy levels, and crank up core body temperature, users can achieve their ideal weight, become more fit, and enhance their overall health without losing muscle mass.

Ingredients

Instant Knockout combines natural ingredients and powerful plant extracts to give you a pharmaceutical-grade fat burner without the side effects that come with a prescription.

Green Tea Extract: Green tea is an antioxidant-rich superfood that gives your metabolism and energy levels a boost. In addition to fat-burning properties, green tea has tons of other benefits, including improving brain function and even reducing bad breath.

Cayenne Pepper Seeds: A natural thermogenic without side effects (unless you have an allergy), these seeds increase your BMR (basal metabolic rate), allowing you to burn more calories without any energy expenditure or side effects. Burn fat while you sleep!

Glucomannan: A fiber from the konjac plant, glucomannan helps you feel full longer so that you can avoid afternoon carb or sugar cravings that harm your diet.

Caffeine Anhydrous: This stimulant supercharges your workout increasing your energy and focus while reducing fatigue and pain by almost 50%.

Vitamin B6: B vitamins help the body in a variety of ways, including metabolic functions and fat oxidation. In particular, vitamin B6 also positively affects the body’s absorption of amino acids, allowing you to build more muscle.

Vitamin B12: Vitamin B12 is known to be an energy and mood booster. It can also influence metabolism and appetite.

GTF Chromium: This multifunctional compound gives you natural energy while also preventing carbs from being stored in the body as fat.

Zinc: Zinc isn’t just for fighting off the flu. This mineral also helps convert the food you eat into energy for enhanced athletic performance.

Piperine: This black pepper extract has thermogenic properties, heating up the body and turning it into a fat incinerator.

Green Coffee Bean: Unlike roasted coffee, green coffee beans have almost no caffeine. Instead, this bean’s main benefit is that it slows down the absorption of fat from the food you eat, while simultaneously reducing sugar cravings.

This fat burning supplement is designed to work throughout the day, so it involves taking one capsule at four intervals – 8 AM, 11 AM, 2 PM, and 5 PM. By equalizing four doses of Instant Knockout instead of taking one concentrated dose, you can maintain fat burning status for longer periods.

Instant Knockout addresses one of the biggest weight loss issues for guys: how do you lose weight without sacrificing lean muscle mass? This fat burner attacks fat stores while leaving your muscle gains intact. It does contain caffeine, including green tea, so make sure you don’t take this one before bed.

#4 HourGlass Fit: Natural Fat Loss Supplement with Good Reviews

hourglass fit

HourGlass is the highest rated fat burning pill for suppressing appetite. Understanding that men and women have different needs when it comes to losing weight, HourGlass Fit rounds out our list of best fat burners for weight loss. In addition to being designed specifically for women, it’s also packed with nutrients that females need to get the most from a workout, whether it’s a leisurely walk or grueling cross fit session.

HourGlass Fit works by addressing the three biggest obstacles to weight loss:

  1. Eating too many calories
  2. Not having energy or motivation to exercise
  3. Food intake

We all know that abs are made in the kitchen, and what we eat is the primary factor in weight loss success. HourGlass Fit contains the ideal blend of natural ingredients to help you beat food cravings and reduce the number of calories you eat, all while giving you an energy boost to make sure you get the most out of each workout.

Ingredients

HourGlass Fit weight loss pills contain no stimulants, so you don’t have to worry about jitters, sleepless nights, or other strange side effects with this supplement. The formula is also vegan, which is a rarity in the fat burner supplement space.

Glucomannan: You’ve seen this ingredient in some of the other fat burner supplements on our list, and there’s a reason for that. This fiber works wonders in helping you feel full without unpleasant and unsightly bloating, according to study after study.

5-HTP: Hormones can sabotage weight loss by making you hungry or killing positive vibes. 5HTP works as a precursor to serotonin, the happy hormone, giving you a sense of well-being while also controlling hunger.

Vitamin B2: You might recognize vitamin B2 as Riboflavin. This vitamin is critical for daily function because it converts the food you eat into energy. Many women are deficient in this vitamin, so HourGlass Fit  gives you a full daily dose.

Vitamin B6: This vitamin is necessary for processing carbohydrates, and it also allows the body to use fat as fuel for energy expenditure instead of storing it as excess fat.

Vitamin B12: We tend to think of weight gain as an inevitable part of the aging process, but more than one study has shown that vitamin B12 can prevent fat accumulation as we age. Plus, B12 is also a natural energy booster without the need for caffeine.

Chromium: Another popular ingredient in fat burner supplements, chromium is key to reducing food cravings.

Zinc: Zinc is vital for overall health, and it also has several weight loss properties, including a positive effect on metabolism.

Capsimiax®: This proprietary blend is a powerful thermogenic that heats your core temperature without causing side effects like sweating. It’s also a natural appetite suppressant.

Bioperine®: Another proprietary ingredient, bioperine® is a more bioavailable form of piperine, which is a black pepper extract that aids in the absorption of other supplement ingredients while also acting as a thermogenic.

For maximum effectiveness, HourGlass Fit should be taken four times daily (one capsule per serving). This dosing gives you constant support, setting you up for fat burning success.

The bottom line is that this fat burner is designed for women that struggle with food cravings. The makers of this formula understand that no matter how hard you work out, if your appetite is out of control, you’ll never shed those unwanted pounds. So, if you find that snacking and hunger cravings are the biggest obstacles in your weight loss journey, HourGlass Fit is for you.

#5 Meticore: Best for Boosting Metabolism

meticore

Meticore is the best metabolism booster on the market. If you’ve been dieting and exercising like crazy, yet those stubborn pounds won’t go away, the problem could be your core body temperature. It turns out that a low core body temperature keeps you from burning calories. It’s estimated that the difference could be as much as 130 calories per day, which, according to one study, could account for a weight gain of over 13 pounds per year.

Now, imagine you’re trying to shed body fat with this 130-calorie disadvantage every single day. You would have to work twice as hard to lose weight and still might not get the desired outcome! By addressing this low core body temperature, you can get to the root of your weight loss problem, resulting in higher metabolism and a situation where the weight literally melts off.

People that have tried Meticore products report that they not only lose weight without negative side effects, but they also notice dramatic improvements in their skin and hair, as well as improved joint mobility.

Ingredients

Meticore is an all-natural, stimulant-free product that’s made in the USA in a facility that’s GMP-certified.

Turmeric Root: This herb is the superfood of the 21st century, being used to address everything from inflammation to cognitive decline. It helps raise core body temperature by absorbing excess water (goodbye, bloating!) and tightening tissues.

Ginger Root: Like turmeric, ginger also has anti-inflammatory properties. It’s also been shown in several studies to aid in weight loss and appetite suppression.

Moringa: This tree leaf can control blood sugar levels in the body, helping to fight food and sugar cravings naturally.

African Mango: This well-known ingredient uses an extract from the seeds to help people lose weight. It’s believed to speed up metabolism, prevent fat build-up, and suppress the appetite for maximum fat loss.

Fucoxanthin: This ingredient is found in brown algae and seaweed. It’s purported to naturally stimulate the body’s fat-burning capabilities. Though it can be consumed directly from the seaweed, there’s debate about how absorbable it is as a food source, so taking it as a supplement is recommended.

Bitter Orange: Though it might look like a delicious citrus fruit, bitter orange is more ornamental than edible. Its claim to fame occurred after the FDA banned ephedra, and dieters were desperate to find a substitute that had the effect of raising the body’s core temperature the way that ephedra was known to do. Bitter orange has the same effect, but it’s all natural and has had impressive results in a weight loss study.

Meticore is one of the easiest weight loss supplements to take. You don’t have to remember to take multiple doses per day. Instead, one capsule a day is all you need, and the bottle includes a convenient one-month supply.

For people that have tried multiple times to lose weight and failed, Meticore could be the solution you’ve been looking for. Most of us could use a metabolic boost, especially when we get older or we’re dealing with stress.

How Do Fat Burning Pills Work?

Fat burners work by increasing your metabolic rate through thermogenesis, a process in which your body burns more calories to produce heat. Thermogenic supplements contain one or more ingredients that help:

  • Boost energy levels
  • Curb appetite
  • Eliminate cravings
  • Access fat stores to use for energy
  • Increase body’s metabolism
  • Increase your body’s core temperature (also called thermogenesis)
  • Regulate hormones
  • Enhance mood

Most fat burners contain caffeine, either in the form of coffee bean extract or green tea leaf extract. If you’re sensitive to caffeine, stick with a fat burner supplement without stimulants.

Factors to Consider Before Buying a Fat Burner Supplement

As you compare different brands of fat burners and review all of the health information, it can be tough to distinguish between them. We’ve included some helpful tips to choose the right fat burner for your needs.

Clinically Dosed Ingredients

When choosing the best fat burner supplements, make sure to look for products that have clinically-dosed ingredients. Many fat burner supplements contain ingredients that have too low of a dosage to have any positive impact on weight loss. This is especially common for fat burner supplements that you can find over-the-counter in stores like GNC.

For example, the clinical dosage for glucomannan is three grams. So if a fat burner contains 500mg of glucomannan, it’s not likely to have a positive effect on suppressing appetite.

Stimulant or Non-stimulant

Many fat burners contain stimulants like caffeine or green tea extract. Whether you want a stimulant in your fat burner is a matter of preference, but you should consider whether you’re sensitive to caffeine. Also, if you’re a habitual coffee drinker or you already take a green tea extract supplement, it’s not ideal to combine coffee with a fat burner that contains a stimulant. Check the label for any warnings about this combination.

Price

The price of fat burners varies based on the ingredients and the size of the bottle. You can’t necessarily conclude that a bottle with 120 capsules is a better deal than one with 30 capsules because some formulas have multi-capsule doses while others are a once-daily supplement.

Customer Reviews

Customer reviews can help give you context about who the product is right for and what kinds of results you can expect. Some customer testimonials are sponsored or paid for, so make sure you look for those disclaimers.

Money-Back Guarantee

Any reputable company will offer a money-back guarantee, though the terms and timeframe may vary. Keep in mind that fat burners take a while to work, and you can’t expect results overnight. However, most brands will offer either a 30, 60, or 90-day money-back guarantee.

Health Benefits of Taking Natural Fat Burners

Natural fat burners have ingredients that help your body function, which results in a lot of health benefits, not just weight loss!

Increased Energy

Though many fat burners contain stimulants like caffeine or green tea extract, even stimulant-free fat burners can still increase energy. That’s because they’re packed with other energy-enhancing nutrients, including B vitamins.

Weight Loss

Most people turn to fat burners to lose weight, and the brands on our list don’t disappoint. The way the weight loss occurs depends on the formula, but when you combine the right burn supplement with regular exercise and a healthy diet, you can expect to lose weight with a fat burner.

Suppressed Appetite

Excess calories are the leading cause of weight gain, so fat burners tend to have powerful appetite suppressants to keep hunger at bay. You don’t need to seek professional medical advice to know that eating fewer calories leads to weight loss and a decrease in body fat with no unwanted side effects.

Boost Metabolism

When you boost your metabolism, you’re burning fat and more calories during your daily routine. Fat burners give your metabolism a boost by providing your body with the nutrients it needs for optimal calorie-burning, while simultaneously including thermogenic ingredients that raise your core temperature. The result of these products is that your body becomes a furnace for burning fat.

How Fast Can You Lose Weight with Thermogenic Fat Burners?

Results vary, and some brands will caution you to wait 90 to 180 days to see results. It’s strongly recommended that you combine fat burners with diet and exercise. When you’re on the right path, you could begin to see noticeable progress within about three to five weeks.

You can monitor your progress by taking before pictures and measurements and then retaking pictures and measurements each week to see if you’ve lost weight and inches.

How to Get the Best Results with Fat Burners

We’d all love a magic weight loss pill, but the reality is that losing weight is hard work. A fat burner on its own will have negligible results unless you’re diligent about working out and eating healthy.

Making smart choices about what you put in your body and how you spend your days will go a long way toward increasing your chances of success. Also, make sure you follow the dosing instructions carefully. Skipping a day, or even a dose, could stall your progress.

Are Fat Burning Supplements Safe for Weight Loss?

The short answer is yes! All the brands we listed in our guide are made from natural ingredients, so there’s nothing harmful or unsafe. As long as you follow the dosing instructions, it’s highly unlikely that you’ll encounter any issues.

The only caveat is that if you’re sensitive to stimulants like caffeine or green tea extract, steer clear of fat burners that contain these ingredients.

Final Thoughts – Are Thermogenic Fat Burners Right for You?

If you’ve gotten this far, then it’s safe to say that thermogenic fat burners are 100% right for you. You can think of thermogenic fat burners as an unfair advantage for weight loss. Following a diet can be tough going, eating bottomless kale salads, and hitting the gym daily. It’s even more frustrating when you put in all that work and see zero results

The bottom line: with a thermogenic fat burner, the results will come because your body now has everything it needs to push the scale in the right direction. Here’s to your diet success!
