Fat Burner Reviews — 10 Amazing Products

Burn Lab Pro Review

OVERALL RATING 9.9
  • Editor’s Pick: Best for bodybuilders
  • Price: From $59.00
  • Ingredients: ForsLean, Capsimax, beta-hydroxy beta-methylbutyrate (HMB), NutriGenesis, BioPerine
  • Form: Capsule
  • Serving size: 3 capsules
  • Servings per container: 30

Burn Lab Pro is a unique bodybuilding supplement on the market, and it’s not only there to help you burn excess fat. It’s made predominantly for people who want to lose fat and gain muscle. It does this so well that it’s widely considered one of the best fat burner 2020 bodybuilding products. 

We say that because of the fantastic mix of ingredients it has. There’s a total of five, and most were made specifically for this product:

  1. ForsLean — from the plant Coleus forskohlii, one of the best plants for improved fat burning, metabolic rate, and muscle growth.
  2. Capsimax — a concentrated extract from red chili peppers known to increase body heat and fat breakdown while also lowering appetite. 
  3. HMB — a chemical our bodies produce to break down leucine, one of the building blocks of protein. It’s used in many top fat burners supplements to promote muscle growth.
  4. NutriGenesis — a trace mineral that helps fitness-driven fat breakdown by inducing several processes like muscle growth and appetite reduction.
  5. BioPerine — a black pepper extract that stimulates body heat and thus accelerates fat burning. 

With this unique and compelling mixture of ingredients, Burn Lab Pro manages to do a lot of things many other fat burners can’t. It’s precisely why we believe it’s one of the best bodybuilding fat burners on the market.

PROS:
  • Uses five potent ingredients to cause a natural fat breakdown in the body
  • Perfect for bodybuilders, athletes, and anyone else looking to burn fat and build muscles
  • Completely vegan-friendly
  • Helps in fat burning and muscle growth at the same time
CONS:
  • A bit expensive when compared to other top fat burner supplements

Legion Phoenix Fat Burner Review

OVERALL RATING 9.8
  • Editor’s Pick: Best for workouts
  • Price: From $34.99
  • Ingredients: Citrus aurantium fruit extract, naringin, green tea extract, 5-HTP, L-tyrosine, salicin, hesperidin, forskolin
  • Form: Capsule
  • Serving size: 5 capsules
  • Servings per container: 30

After careful reviewing, we’ve found that Legion Phoenix Fat Burner is one of the best natural fat burners supplements on the market as it perfectly suits anyone who knows how to maintain a regular diet and exercise regimen. With it, you can burn up to 183 additional calories every day, which should be more than enough for normal weight loss. 

What’s truly interesting about this fat burner is that it doesn’t cause you to regain weight once you stop using it. As long as you follow a regular, healthy eating plan, the lack of Legion Phoenix won’t cause you to gain more weight.

We also count this product among the best fat burning supplements as it’s not made to be a stimulant, like many other fat burners. It doesn’t even have caffeine in it. 

Furthermore, it was almost impossible to find a downside to this fat burner, which shows how good it is. The only thing we don’t like and what most people complain about is that you have to take five pills every day. However, it’s a small price to pay for near-perfect fat loss!

PROS:
  • 100% natural fat burner
  • One of the best strong fat burners that’s not a stimulant
  • GMP-certified and tested by third parties
  • No milk, fish, eggs, soy, shellfish, peanuts, or wheat
  • 100% money-back guarantee
CONS:
  • You have to take three pills in the morning and two later in the day
  • Some customers complain that it doesn’t help much with appetite reduction

Transparent Labs Fat Burner Stim-Free Review

OVERALL RATING 9.8
  • Editor’s Pick: Best stimulant-free fat burner
  • Price: From $49.00
  • Ingredients: Vitamin B12, acetyl L-carnitine, ForsLean, 5-HTP, Rhodiola rosea, cayenne pepper, fucoxanthin
  • Form: Capsule
  • Serving size: 2 capsules
  • Servings per container: 60

One of the best fat burner pills without stimulants on the market, Transparent Labs Fat Burner Stim-Free is also one of the top fat burners overall. 

It’s quite similar to the company’s main fat burner product, but it contains no green tea extract or caffeine, making it completely stimulant-free. However, the remaining ingredients are more than suitable for everyone looking for a fat burner with no stimulants, which many people are. 

One of the best things about Transparent Labs products, including this top fat burner supplement, is that the brand explains everything you need to know about the efficacy of its products, all through approved studies. All the ingredients in the product are clean and natural, and combined using a science-based formula. 

What’s more, you can view explanations for each of the ingredients and how they work directly on the official site of the product. 

All in all, the supplement works by targeting the most important factors in weight loss, including fat storage, energy, appetite, and metabolism.

PROS:
  • Perfect for anyone looking for the strongest fat burner without stimulants
  • 100% natural, non-GMO, and gluten-free
  • 100% transparent formula and ingredients
  • Very affordable when you consider the number of servings you get from one bottle
CONS:
  • Not perfect for people who don’t like taking more than one pill per day

Swiss Research Labs Limited Trimtone Review

OVERALL RATING 9.6
  • Editor’s Pick: Best for women
  • Price: From $59.95
  • Ingredients: Caffeine, green coffee, green tea, grains of paradise, glucomannan
  • Form: Capsule
  • Serving size: 1 capsule
  • Servings per container: 30

Trimtone is often dubbed the best fat burner for women, and we believe it’s for a good reason. 

First of all, the whole formula behind the product was specifically created for women. 

Second, this fat burner is 100% natural and thus entirely healthy to take. 

Third, and most importantly, all the natural ingredients used in the product are there because they profoundly enhance weight loss. 

There’s no doubt about the product’s effectiveness. The formula stimulates your metabolism, suppresses your appetite, and speeds up thermogenesis. 

Thermogenesis is crucial because if you’re looking for the best fat burners, the best you can do is find one that speeds up thermogenesis, as this is literally the process of heat production in a living organism. The more heat your body produces, the more fat it will burn. It’s as simple as that. 

Naturally, the product is as effective as such a pill can be. You have to take it daily, as recommended, and you’ll still have to continue with a healthy lifestyle, meaning you’ll have to eat healthily and exercise regularly. 

All in all, Trimtone is one of the best fat burning pills, as it supports several processes in your body that burn fat, and all of them combined are more than enough to get you to burn that excess fat you have.

PROS:
  • Prevents your body from absorbing and accumulating lots of fat
  • Boosts metabolism, thus getting the body to burn excess fat faster
  • Doesn’t cause rebound weight gain
  • 100-day money-back guarantee for unopened bottles
  • Free shipping for orders of three or more bottles
CONS:
  • Not suitable for vegetarians and vegans
  • You can only buy this strong fat burner from the official Trimtone website

LeanBean Review

OVERALL RATING 9.5
  • Editor’s Pick: Best for suppressing hunger
  • Price: From $59.99
  • Ingredients: Konjac fiber (glucomannan), choline, vitamin B6 and B12, chromium picolinate, zinc, potassium, turmeric root, green coffee bean extract
  • Form: Capsule
  • Serving size: 6 capsules
  • Servings per container: 30

LeanBean is one of the few best fat burner in 2021 products that target the main problem with weight — hunger. The entire formula of this supplement is targeted towards subduing hunger, and the fact is that LeanBean does this in the best way possible if you want to burn fat without harming your body in the process. 

Even though LeanBean is perfect in its simplicity, it does have a few minor downsides, like the fact you have to take six pills every day, which is a bit of a nuisance for some. 

Likewise, while it might potentially be the best fat burner supplement for women on our list, it’s definitely not the cheapest. Finally, on some rare occasions, it can cause digestive issues due to the high concentration of fiber. However, as fiber is among the best natural ingredients that will help you suppress hunger, this is not something you should have a problem with. 

You’ll also love how it works. The glucomannan dietary fiber keeps you feeling full and suppresses your cravings, especially sugar cravings. It also increases your energy levels, improves your metabolism, and reduces tiredness and fatigue, all of which together help you burn fat. In essence, all of this makes it one of the most effective fat burner products out there.

PROS:
  • Perfect for people with problematic food cravings
  • Made in FDA-registered facilities
  • 90 days money-back guarantee
  • GMP-certified
  • Vegan supplement, ideal for women
CONS:
  • A bit expensive for some
  • You need to take a total of six pills every day

Jacked Factory Lean PM Review

OVERALL RATING 9.3
  • Editor’s Pick: Best fat burning supplement for sleep
  • Price: From $15.99
  • Ingredients: Vitamin B6, magnesium, EGCG from green tea, L-theanine, 5-HTP, melatonin, black pepper fruit extract
  • Form: Capsule
  • Serving size: 2 capsules
  • Serving per container: 30

While making these fat burner reviews, we were very surprised to find this unique fat burner supplement. Jacked Factory’s Lean PM is a truly unique fat burner as it does its job during the night while you’re sleeping. 

But how does it do that, and what makes it so good?

Well, it uses a unique formula that promotes better sleep while at the same time lowering your hunger and promoting natural fat burning processes. 

This incredible science-based formula with several healthy ingredients like magnesium, vitamin B6, and melatonin makes this the best fat burner for beginners. It doesn’t contain any strong ingredients like stimulants, which are certainly not ideal for someone taking this kind of supplements for the first time. 

On top of that, you only need to take two capsules with a glass of water every day, some 40 minutes before going to bed. 

The product also comes in different sizes, and you can even choose a bottle without melatonin. What’s more, the cheapest bottle is only $15.99, which makes it the best fat burner on the market for people on a budget.

PROS:
  • Perfect for beginners who are not looking for stimulants in their fat burner products
  • Promotes fat burning processes while you sleep
  • Helps you fall asleep faster
  • Lowers food cravings
  • Very affordable
CONS:
  • Some people are not happy with the quality of sleep they get from this fat burner
  • Not ideal for people looking for additional herbal appetite suppression ingredients

PhenGold Fat Burner Review

OVERALL RATING 9.2
  • Editor’s Pick: Best premium fat burner
  • Price: From $79.95 (much cheaper if you buy two or more packages)
  • Ingredients: Vitamins B3, B6, B12, green tea, L-tyrosine, Rhodiola sp, L-theanine, caffeine anhydrous, green coffee, cayenne pepper extract
  • Form: Capsule
  • Serving size: 3 capsules
  • Servings per container: 30

If you’re looking for the best fat burner of 2020, you can’t go wrong with PhenGold, at least if you’re prepared to pay a premium price. 

It’s definitely the best premium fat-burning product on the market at the moment. It effectively increases your metabolism rate, suppresses hunger, and improves the body’s natural fat-burning processes. 

All of this is possible due to the many beneficial ingredients it contains, but also the unique formula these ingredients are combined in. It’s filled to the brim with natural ingredients like green coffee, cayenne pepper, Rhodiola sp, and most notably, a high amount of green tea. All of this makes PhenGold one of the best natural fat burner supplements on the market. 

We also want to mention that it contains L-theanine and L-tyrosine. The first boosts metabolism, effectively preventing more fat gain, while the latter slows down the loss of certain neurotransmitters that keep you active for longer, like adrenaline and dopamine. 

In the end, it’s worth noting that even though this is one of the more expensive top-rated fat burners, it’s much cheaper if you buy more, plus you get additional packages for free. A 2-months supply gets you a month for free ($120.90), and a 3-month supply gets you two additional months for free ($184.85). 

On top of that, you can return unopened bottles if you end up disliking the product, so there’s nothing to lose.

PROS:
  • Completely vegan-friendly
  • Perfect for anyone willing to pay a high price for a top fat burner with premium ingredients
  • No artificial ingredients or fillers and dyes
  • Soy- and lactose-free
  • 100-day money-back guarantee for unopened products
CONS:
  • High price
  • People who don’t want a robust ingredient list might not need it

Instant Knockout Review

OVERALL RATING 9.2
  • Editor’s Pick: Best for a lean body
  • Price: From $59.00
  • Ingredients: Vitamins B6 and B12, zinc, green tea extract, green coffee extract, cayenne powder, caffeine anhydrous, black pepper extract
  • Form: Capsule
  • Serving size: 4 capsules
  • Servings per container: 30

Many state that Instant Knockout is the best fat burner for men, and it might be, but it’s still an excellent fat burner for women as well. The main benefit of this supplement is that it’s perfect if you’re looking to create a lean body, which is something that every fat burner supplement should be able to do, but that’s not always the case. 

With Instant Knockout, it most certainly is. If you’re having trouble getting rid of that excess fat, even with challenging exercises and a great diet plan, then this might be the product you’re looking for to finally push you over that edge.

Instant Knockout does this by being the best natural fat burner supplement you can find for the money. We say that as it uses a perfect combination of ten extremely beneficial ingredients. 

Some of the most notable ones are green tea extract, cayenne pepper seeds, and glucomannan. These ingredients together do the hard job that your body fails to do well enough on its own, even with strenuous exercise and diets. 

They help reduce food cravings, suppress appetite, boost energy levels, improve your metabolism, speed up fat burning processes, and retain muscle mass. This is truly one of the top fat burners for men and women as it does everything you need to end up with a lean body!

PROS:
  • Perfect for athletes and people looking for a leaner body
  • All ten ingredients are proven to help with weight loss and muscle retention
  • Limits both sugar and regular food cravings
  • Doses are evenly spread throughout the day, which maximizes fat burning processes
  • Best belly fat burner pills for persistent fat
CONS:
  • You have to take a capsule four times throughout the day
  • Not for vegans and vegetarians as it has gelatin

AbCuts CLA Belly Fat Formula Review

OVERALL RATING 9.0
  • Editor’s Pick: Best for belly fat
  • Price: From $19.99
  • Ingredients: Vitamin E, omega-3 fish oil, flaxseed oil, sesame seed oil
  • Form: Softgel
  • Serving size: 2 softgels
  • Servings per container: 40

AbCuts CLA Belly Fat Formula is a unique product on this list. It’s certainly one of the best fat burners on the market, even if it focuses on belly fat. However, we say it’s unique because it offers a different formula than most other successful fat burners. 

Notably, the AbCuts fat burner uses vitamin E and omega-3 fish oil, together with a few other natural oils. All of these ingredients work well together to help you reduce weight and especially body fat, most notably stomach fat.

We also had to add it to our best fat burner reviews for 2020 and beyond as it’s one of the few supplements of this type that come in the softgel form. As many of you would probably agree, softgels are much easier to swallow, and many claim that our bodies absorb them better than regular capsules. 

The only downsides to the AbCuts fat burner are that it contains or might contain some allergens and is not suitable for vegans and vegetarians. However, the brand makes up for it by offering one of the leading supplements to burn belly fat without any stimulants that are present in many other fat burners.

PROS:
  • Contains healthy omega-3 fatty acids
  • Very effective at burning belly fat
  • Contains no stimulants
  • Comes in easy-to-swallow softgel form
  • Fairly inexpensive
CONS:
  • Some customers say it doesn’t provide enough results, even with exercise and dieting
  • Contains, or might contain, several allergens, including animal products

Hourglass Fit Review

OVERALL RATING 8.9
  • Editor’s Pick: Best all-natural fat burner
  • Price: From $55.00
  • Ingredients: Vitamins B2, B6, B12, chromium, zinc, konjac root extract, black pepper extract, cayenne pepper extract, 5-HTP seed
  • Form: Capsule
  • Serving size: 4 capsules
  • Servings per container: 30

Hourglass Fit is the best natural fat burner currently on the market. Even though it mostly targets women, men can use it as well with equal effectiveness. That’s because it uses one of the best and healthiest all-natural formulas in the fat burner industry. 

No matter what you’re looking to achieve, the great thing about Hourglass Fit is that it can assist you with a range of weight loss goals. The formula behind this product can help you achieve a lean, healthy body, just the way it’s supposed to be. 

This is not just a fat burner, but the best fat burner appetite suppressant as it uses glucomannan, a dietary fiber from the konjac root. It’s known to be the best appetite suppressant found in nature, which many other fat burners use. 

Furthermore, Hourglass Fit uses 5-HTP, which helps uplift your mood, and zinc, known to help numerous processes related to fat burning. But that’s not all, this excellent weight loss supplement also uses several vitamins and other healthy nutrients that help your overall health, which can only lead to the desired weight. 

When all of this is considered, Hourglass Fit is clearly one of the leading fat burning products on the market, one that might be perfect for you as well.

PROS:
  • Uses completely natural and healthy ingredients
  • Perfect for vegans
  • Made for women, but great for men as well
  • Free of GMOs, soy, and gluten
  • Free and fast shipping for larger orders
CONS:
  • You need to take four pills every day
  • The dose of glucomannan could be higher

How to Choose the Best Fat Burner — Buyer’s Guide

Now that we’re done with the reviews, it’s time for you to find a way to make a choice. As we know that choosing the exact product that will suit your needs the most is hard, we’ve prepared a detailed buying guide. In it, you’ll find the explanations and advice that will make your decision much easier. Let’s take a look. 

First Learn How Fat Burners Work

Fat burner supplements are compounds with different ingredients, and they help your body burn fat faster than usual. They do this in a wide variety of ways, by combining different methods or using only some of them. In essence, fat burners typically use ingredients and formulas that are also often used in the best available appetite suppressants, and that are meant to enhance fat burning processes, improve metabolism, increase energy and body temperature, and more. 

When you consider all of this, no fat burners alone can do what the name suggests, not even the best fat burning products. They only help the body burn fat on its own. 

However, the processes fat burners enhance and what they do is more than enough to provide assistance in weight loss, which is precisely why they are often effective. 

Naturally, in order for these supplements to be effective, you still need to exercise regularly and eat healthy foods. In other words, not even the top fat burning supplements can substitute any of these things. 

Check the Ingredients

One of the most important factors to consider when looking for good fat burners are the ingredients. They might even be the most important factor as a fat burner is only as good as its ingredients.

So, look for supplements that contain ingredients known to help with weight loss and fat burning. So, ingredients like high-quality green tea extract, coffee bean extracts, chromium, caffeine, protein, fiber, and more. 

Consider the Price

No matter how much you’re ready to spend on any of the top 10 fat burners we reviewed here, you still need to consider the price. This is very true as you’ll likely have to take these supplements for longer than one package lasts. 

However, don’t settle for cheaper alternatives if they don’t offer the results you’re looking for. 

You can also compare the prices of the supplements we recommend by calculating the price per serving to better understand how much it costs. Also, take into account the price reductions these brands offer, especially on larger orders. 

Safety of the Supplement

Most effective fat burners use natural ingredients, but they still tend to use stimulants or allergens in their formula, which is why it’s crucial to check the ingredients. Moreover, you also need to check with your doctor whether it’s safe to use them, especially if you have a condition or you’re using some other medications. 

Fat burners typically only cause minor side effects, but they can cause significant problems for some people, so check all of this before taking one. 

Conclusion

So there you have it folks, our detailed reviews of every best fat burner currently available on the market, including a comprehensive buying guide that should help you decide which one to choose. 

All the information here should be more than enough to help you, and we hope that the product you select will deliver the results you need and deserve to get!

FAQs

What are fat burners?

If you’re on the path of finding the best fat burner for weight loss, you have to first understand what they are exactly. We talk more about them in the buyer’s guide, but in short, fat burners are dietary supplements or other forms of supplements that help you burn excess fat. 

All fat burners claim they do this successfully, but the truth can always be found in their ingredients. Most use natural ingredients like caffeine and yohimbine in order to improve your metabolism, increase the speed of fat burning processes, suppress appetite, and more. 

However, the crucial thing about every best fat burner supplement is that they assist you and your body in fat reduction, which means you still have to lead an overall healthy lifestyle. You cannot overeat, exercise little, and then expect a fat burner to destroy the fat on its own.

Do fat burners really work?

As we’ve already explained, fat burners can work, as long as you’re leading a healthy lifestyle, with enough exercise and without overeating. However, if you’re looking for scientific proof, at the moment, no evidence conclusively states that fat burning supplements burn body fat. 

On the other hand, the fat burners we recommend use ingredients known to assist in fat burning when taken individually. So, if you use fat burners with these ingredients in their recommended doses, you stand to gain some benefits.

Are there any side effects to fat burners?

As is usually the case with dietary supplements, even the best belly fat burner products can have side effects. Thankfully, most side effects are typically rare and more of a nuisance than a real issue, especially in great fat burners.

Here are the side effects that have some potential of occurring in a few fat-burning supplements on the market:

  • Lack of sleep due to stimulants that exist in many fat burners
  • Behavioral changes like nervousness, irritability, and mood swings
  • Anxiety from weight loss and possible cortisol increase
  • Stomach issues like constipation, irritable bowel, and diarrhea
  • Increased blood pressure from higher metabolism rate
  • Allergies and insomnia from artificial ingredients (if the supplement has any)

When to take a fat burner?

The answer to this question depends on the exact fat burner supplement you want to use. How and when to take the product is a question that’s always answered on the label or product instructions. 

In general, you will need to consume a fat burner before breakfast and before a workout. Some 30 to 40 minutes before breakfast is ideal as our metabolisms are at their lowest in the morning, which is why it’s the perfect time to speed them up. As for the time before a workout, it’s also perfect as this is an excellent way to get an extra kick to your calorie-burning efforts during the exercise itself.

What is the best fat burning supplement?

As is always the case, there is no single best of anything, let alone a single best fat burner. There are several leading fat burning supplements, and it’s up to you to choose one that works best for your needs. 

In this review, you’ll see that each supplement is best for a specific need or a particular set of people, so all you need to do is find the one that works for you. However, make sure to check our detailed buying guide, as it should help you reach the right decision in the end and get a supplement that won’t disappoint you.
