Anyone who’s ever tried to lose fat would have tried to find, or at least research about, the best thermogenic fat burner.
But chances are, that most of the products that you bumped into, were either shills or outright scams.
Weight loss is a trillion dollar industry that thrives on exaggerated claims, hype, aggressive marketing and most of the times, unscrupulousness.
To make things worse, there are only a handful of natural ingredients that are scientifically proven to produce thermogenesis.
For those who are new to this, ‘Thermogenic’ means ‘Heat inducing’. When described in a weight loss context, it stands for products that increase your body temperature ever so slightly, which accelerates fat loss.
When used effectively, the best thermogenic fat burner can help you burn fat selectively. This means, that you will not have to struggle with weeks of crash diets, calorie monitoring or risk losing your hard earned muscle mass.
You can pop a pill and watch the fat melt away. All said and done, thermogenic is an extremely risky proposition as well. There are chances that you may be sold something as toxic as DNP.
That’s where we step in. We have handpicked the best thermogenic fat burners out there and rated them, based on their efficacy, safety and tolerability. Strap in and enjoy the read.
Top 5 Thermogenic Fat Burners in 2021
#1 – Leanbean – Best Thermogenic Fat Burner for Women
Leanbean is an all-natural thermogenic fat burner that’s designed for women. Now, that might seem gimmicky at first.
How and why design a fat loss supplement purely for women? Aren’t weight loss supplements meant to be universally compatible?
To understand this, it’s important to know the physiological differences in the two sexes. Here’s a clinical studythat shows that women have different food cravings than men and hence, are likelier to be obese.
Here’s another one that shows that women are 15% likelier to snack as compared to men.
That’s precisely what Leanbean is designed to combat. It is a combination of 11-natural ingredients, all science-backed, which help women curb hunger pangs, bumps their metabolism and keeps them energized all day. There are no pharmaceuticals, stimulants, additives or other proprietary nonsense, which we consider huge red flags.
The result, is safe and sustainable fat loss.
Why we like it
Eventually, it all boils down to what’s inside the pill, doesn’t it?
This is why LeanBean tops this list. It only contains science-backed, 100% natural ingredients.
Choline – This powerful nutrient has for long been studied for its potential benefits in improving brain health. However, a little known innate benefit of this supplement is that it accelerates the rate at which your body breaks down stored fat, and uses it for energy. It has also been proven to increase satiety, which means that you are less likely to binge eat, even when you are on a calorie deficit diet.
Glucomannan – This naturally occurring water-soluble dietary fiber is so effective at curbing hunger pangs, that people report feeling full for hours after a tiny dose. It’s extracted from Elephant-Yam. LeanBean contains 3g of Glucomannan in every serving, which is more than what you get with any other best thermogenic fat burner. In a nutshell, if controlling your hunger is your biggest weight loss hurdle, LeanBean is your ticket to glory.
Chromium Picolinate – Chromium Picolinate is a variant of the mineral Chromium, that’s tweaked ever so slightly for better absorption. It is a very effective natural ingredient that helps stabilize blood sugar levels, which can go haywire with dieting. It also helps control hunger pangs.
B6 & B12 – B-Vitamins are critical to normal every day functioning. It keeps you energized all day, even if you are in a calorie deficit. Not to mention that it improves cognitive functioning, boosts your mood and prevents brain fog. Picture feeling bright, energetic and cheerful all day during your weight loss journey.
Chloride – This underrated electrolyte is associated with a plethora of beneficial effects, including maintaining fluid levels. Chloride often works in synergy with other electrolytes. It’s one of the first electrolytes that can get depleted when you are trying to lose weight. LeanBean ensures that your electrolyte levels stay stable.
Garcinia Cambogia – This natural flavor-inducing ingredient used extensively in Asian cuisine, has been linked with a noticeable reduction in visceral fat levels. That’s not all. It helps reduce hyperlipidemia, is anti-inflammatory, anthelmintic and hepatoprotective.
The powerful 5 – LeanBean also contains Green Coffee Bean extract, Zinc, Turmeric, Piperine & Acai Berry, a stack that we call the Powerful 5. Each one of these ingredients are scientifically proven to help curb hunger, improve overall health, boost metabolism and increase fatty acid oxidation.
LeanBean Shipping & Return Policy

#4 – Instant Knockout – Best Natural Fat Burner
Enough about the best thermogenic fat burner that has been around for years. Here’s a swanky, new addition to this list. This is Instant Knockout, a 2021 fat burner that helps you achieve an MMA fighter’s physique that’s ripped, hard and fat-free.
It’s recommended by Diego Sanchez, Greg Jackson & John Dodson III, three of the biggest names in MMA.
Here’s the typical checklist for an MMA fighter.
That’s precisely what you get with Instant Knockout. Ever since it was launched, Instant Knockout has become so popular, that it’s now one of the bestselling fat burners in the world.
Why we like it
Instant Knockout is designed for fast results. It’s not the cookie-cutter fat burner with a few mild ingredients that give you a slight boost to your efforts. This is the real deal. It’s potent and it gets the job done.
Instant Knockout Ingredients
We love the fact that there are only scientifically proven ingredients in Instant Knockout.
Green Tea Extracts – Green Tea Extracts is crammed with antioxidants and polyphenols. But it’s also one of the most effective natural fat burners in the world. There are multiple clinical studies that back this claim. It is this ingredient that helps switch off the Alpha-2 receptor in your body.
Cayenne Pepper – Think burn! All day long. That’s what Cayenne pepper brings to Instant Knockout. This is the side-effect free thermogenic that you always wanted. As an added bonus, it also contains vitamin A, C and B6.
Glucomannan – Water soluble fiber from the Konjac plant that keeps you full for hours. Glucomannan is clinically proven to help users lose weight.
Caffiene Anhydous – Get a stable and steady supply of energy, all day long. Think of it like the more potent version of your espresso shot. As a bonus, it also boosts fat oxidation.
B-Vitamin Stack – Instant Knockout contains Vitamins B6 & B12 which work in synergy to amplify your metabolism. These vitamins are also associated with a plethora of other health benefits.
In addition to this, it also contains Chromium, Zinc, Piperine & Green Coffee bean extracts.
Instant Knock out Shipping and Return policy

The best part is that deliveries are faster than what you expect with most other brands, because they have warehouses in UK & USA. This allows them to ship out orders from the warehouse closest to the destination address.
Unfortunately, there’s no money back guarantee on offer. We doubt if you’ll ever need it though for any of these five brands.
Instant Knockout Pros and Cons
There are tons of positive reviews for Instant Knockout. Customers speak about how it has helped them drop loads of body fat in very little time.
Some of the best testimonials come from pro athletes who are all praises for the consistent energy and amplified mood they get from Instant Knockout. It helps them train much harder, which again leads to better results.

Verdict – If you are looking for fast results, go for Instant Knockout. It is hands down, the best thermogenic fat burner in this list.
#5 – Powher Fat Burner – Best Weight Loss Pills for Women
Last but not the least, we have Powher, another strong thermogenic fat burner from Ultimate Life.
In case you didn’t notice, this is the same brand that manufactures LeanBean. Just like LeanBean, Powher is also designed primarily for females, who grapple with binge eating.
Many female athletes and fitness buffs that we have spoken to, find unisex and male fat burners, too strong, or leaning more towards the thermogenic side of things. Powher aims to tick the boxes that females look for, while shopping for fat burners. It helps them curb their appetite and control frequent, unhealthy snacking.
Why we like it
Powher’s ingredient list is completely different from LeanBean and most other weight loss supplements that we’ve reviewed.
B-Vitamin blend – Most fat burners have Vitamins B6 & B12 in their ingredients. But none have Vitamin B5, also known as Pantothenic acid. This very underrated vitamin helps you reduce weight without the unpleasant effects associated with it. The result of this blend of three vitamins is improved metabolism, better mood, razor sharp focus, mental clarity and of course, weight loss.
Green Coffee Bean – This powerful extract is a concentrated form of Green Coffee. It helps alter body fat composition and upregulates fatty acid oxidation. It’s currently considered one of the most powerful natural fat burners.
EnXtra – If you are caffeine intolerant, or are trying to avoid it for some reason, you’d be glad to know that Powher contains EnXtra, which is a natural caffeine alternative. This botanical ingredient is extracted from the rhizomes of Alpinia galangal and produces much better focus as compared to caffeine.
Beetroot and L-Citrulline – Powerful combination that provides a variety of benefits. Use it as a pre-workout stack to increase circulation and vasodilation. It also helps control blood pressure.
In addition to this, Powher also contains a blend of essential vitamins and botanical extracts that improve your overall quality of life.
Powher Shipping and Return policy
Powher is shipped globally. What’s amazing is that you can get free worldwide shipping by just ordering a two-pack.
Deliveries are trackable and within reasonable time frames. In the US & UK, it’s 3-10 days, which is excellent. 10-15 days is the average time span for the rest of the world.
If the products don’t work for you, you can always request a refund within 7-days of delivery. They have a great customer service team who will instantly initiate a refund, minus the shipping and handling costs of course.
Powher Pros and Cons
Powher customer reviews
Despite being a reasonably new product, Powher has managed to garner some rave reviews. There are females who have been able to adhere to calorie-restricted diets with Powher.
Judith Granados from DC is one such fitness buff. She wanted to hop on to the 1500-calorie diet being promoted by her favorite fitness influencer. But she failed three times before achieving it with Powher. In the end, it was smooth sailing. She says that she never felt that she was eating less than 1500 calories. It kept her feeling full and active all day.
Overall, the reviews are largely positive. None of the users have experienced even the mild side effects associated with other fat burners.
There are two products that you can buy. There’s Powher Cut, which is the fat burner in the capsule form and there’s Powher Up, which is the pre-workout drink.
You can of course, consider buying single bottles as well. For more details, click here.
Verdict – Powher is a very versatile fat burner. It’s incredibly effective in curbing hunger pangs. Moreover, females also have the option to club it with the pre-workout drink to get a noticeable energy boost without the jitters.
The Best Thermogenic Fat Burner Buying Guide
There’s a lot of noise and hype in the world of weight loss products, as we mentioned at the onset. This makes it very difficult for someone who’s new to navigate this landscape. Here’s a brief buying guide that explains what features to watch out for while shopping for the best thermogenic fat burners.
The Ingredients – Any fat burner is only as good as the ingredients in it. Always look for products that have clean labels with minimal ingredients. You have to be vigilant about synthetic additives, especially DNP. It’s an incredibly toxic substance that can also cause death. Any natural ingredients that claim to burn fat, or induce a thermogenic effect need to be backed with clinical studies. If there are no studies to back an ingredient, or the studies are inconclusive, that’s a red flag. Some of the best natural fat burning ingredients are Green Coffee bean, Glucomannan, Garcinia Cambogia, chromium picolinate, Choline, B-Vitamins, Caffiene, Capsicain and Piperine.
Brand reputation – Always buy from brands that have a solid reputation. Check customer reviews, read testimonials, check social media pages and messaging boards. Check the manufacturing process. Are the products manufactured in GMP-certified, clean facilities? Speak to the customer care team before placing the order to get a general feel of how they operate. This is why we have only selected trusted brands with a great reputation.
Money Back Guarantee – Not all brands offer a money back guarantee. But most of them do. If you are unsure of whether a particular product will work for you, then a money back guarantee will help you claim a refund if things go south.
Side effects – If you choose the best thermogenic fat burner with natural ingredients, you will not have to worry about side effects. At best, you might experience mild nausea or an occasional headache. Having said that, if you have any known allergies, you might want to cross check with the ingredient list.
If you still have doubts about fat burners in general, then this brief FAQ aims to answer them.
Some fat burners are appetite suppressants and help curb binge eating. Others are fat blockers, which prevent the body from making new fat cells.
But as always, keep an eye on the product label.
That’s it folks. That sums up our list of the best thermogenic fat burners. We hope that this helps you make an informed choice, and helps you achieve your weight loss goals.
