Best Fat Burner for Women in 2020


1) Instant Knockout

Instant Knockout Fat Burner

In first place is Instant Knockout.

This is a fat-burning supplement, originally designed to help MMA fighters and boxers lose fat and get lean before weighing in for a fight.

Instant Knockout claims to slow down or stop fat-storing by boosting metabolism, suppressing appetite and giving you energy to perform a more intense workout. We’ve seen these big statements before from just about every fat-burner, but we were stunned to find out this one delivers on all accounts.

We put it to the test with a rigorous SMG review, designed to find out if it lives up to these big claims.

Although designed for pro-MMA fighters, we think this formula could be ideal to help to melt away those last few inches of unwanted fat many women struggle with.

Needless to say, we were impressed. Instant Knockout used to be on top of our list, after all. But what makes it stand out from the rest? And why is it one of our favorite fat-burner supplements for women? Read on and find out. 

What’s in Instant Knockout?

1. Green tea extract

We know this is one of the most effective thermogenic ingredients on the market. A resounding 11 independent trails identified fat-burning properties in green tea extract.

2. Cayenne Pepper Seeds

Not only are cayenne pepper seeds full of vitamins, we also know this ingredient as a potent thermogenic, effective at boosting your metabolic rate.

3. Glucomannan

Glucomannan is also known as konjac root extract. When it hits your stomach it expands, making you feel fuller, suppressing your appetite and reducing the risk of hunger-induced cravings or over-eating.

4. Caffeine Anhydrous

Caffeine is common in fat-burners and we’re always wary of products that just pump their weight-loss pills full of it. However, with Instant Knockout, the stimulant is at a much lower dosage than other fat-burners and is added with the aim of improving focus and energy.

5. Vitamin B6

In a controlled clinical trial, B6 or pyridoxine was shown to increase fat oxidization which can directly contribute to weight loss.

IngredientsAmount per serving
Vitamin B6 (Pyridoxine Hydrochloride)5mg
Vitamin B12 (Cyanocobalamin)10mcg
Zinc (as Zinc Oxide)10mg
GTF Chromium (as Chromium Picolinate) 100mcg
Green Tea Extract 500mg
Green Coffee Extract100mg
Cayenne Pepper 100mg
Glucomannan (Konjac Root)1800mg
Caffeine (Caffeine Anhydrous)300mg
Black Pepper Extract (Standardized to 95% PE)10mg

How to take Instant Knockout

Timing is everything when it comes to getting maximum benefit out of the appetite suppressant in this mix. It’s a good idea to take the supplement before you sit down for a meal, to ensure portion control and avoid snacking.

We suggest using the following pattern to help control your food intake:

  • One capsule immediately after waking up, before breakfast
  • One capsule between breakfast and lunch
  • One capsule an hour after lunch
  • One capsule an hour before your evening meal

Instant Knockout price:

  • $59/£35 for one bottle
  • $118/£70 for two bottles
  • $185/£110 for three bottles + one free bottle + free delivery

What are people saying about it?

Instant Knockout is a well-known, well-established fat burner supplement, so we didn’t struggle finding reviews of the product online.

One thing that really stood out to us was how many high-profile sportspeople recommended Instant Knockout as their fat burner of choice. In particular, UFC fighters like John Dodson, Holly Holm, and Diego Sanchez have recommended the supplement.

While we know this may be an endorsement, it is reassuring that these established athletes had enough trust in the formula to put their names to it.

To complement this, we found a huge number of positive testimonials, indicating how successful the supplement can be when accompanied by the right diet and exercise.

Of course, we also found a number of reviews where the customer failed to see results from taking the supplement. Without understanding more about their lifestyles and eating habit, it’s hard to know whether other factors may have played a part in this lack of success.

  • Combines intelligent ingredients
  • Uses multiple approaches to control diet and burn fat
  • The formula is completely natural and safe
  • Very low risk of side-effects
  • No proprietary blends
  • Backed by scientific research and studies


  • Premium product attracts a premium price


When accompanied with a calorie-restricted diet and an active lifestyle, we think you’ll struggle to find another fat burner as effective as Instant Knockout.

We have to admit, we were excited to discover Instant Knockout.

When we studied the product and formula, we were happily surprised. The science all adds up, the formula is entirely natural, and it provides a three-pronged approach to fat-loss that could really work for women.

It’s free of unknown synthetic chemicals, it’s completely safe and every ingredient in the formula is proven to aid the fat-burning process. No fillers in sight.

The drawback with this supplement is the price – at $59/£35 it’s at the more expensive end of the spectrum.

Despite this, we’d still consider Instant Knockout great value for money. It’s a high-quality supplement that’s worth paying a little extra for.

Where can I buy Instant Knockout?

Instant Knockout is only available from the official website:

The manufacturers say this is to ensure product guarantees are met and customer service issues are resolved by their team.

Is Instant Knockout safe?

The natural formula profile of Instant Knockout, along with the reasonable dosage of caffeine makes this one of the safest formulas available.

Because the stimulant serving is low, it’s not a huge concern, but you should always account for the extra caffeine in your diet.

You should also avoid high levels of caffeine if you’re pregnant.

Does Instant Knockout work?

Science indicates that this fat burner should help you accelerate your weight loss efforts. However, it’s a supplement and is only designed to complement exercise and a calorie restricted diet.

When it comes down to it, an active lifestyle and calorie restricted diet is the key to losing weight. A fat burner like Instant Knockout will simply enhance your results.

*Individual results may vary. Please speak with your doctor or physician before undertaking any new weight reduction, supplement, or exercise regime

2) Hourglass

Hourglass Fat Burner

Coming second on our list of favorites is Hourglass, a women’s only fat burner – Hourglass.

The minds at Propura claim to have designed an intelligent fat burner that will help you achieve your figure goals. We carefully reviewed every element of this formula to establish whether or not Hourglass really is as smart as they say, and we were happily surprised.

The manufacturer has crafted a completely natural formula, which contains a number of key ingredients that work together to provide women with a comprehensive dieting support system.

Everything in the formula is high-grade and should help you maximize the results from your diet and active lifestyle. Although we can see thermogenic and appetite suppressants in the mix, we did notice the supplement is free of added stimulants, so we were intrigued to see how it provides energy.

However, we know so many women prefer a stimulant-free formula, so we like what we’re seeing in that aspect.

Overall, we were impressed by the quality of the formula – it’s one of our favorites. We spotted several highly concentrated variations of key ingredients, complimentary elements and powerful doses.

What’s in Hourglass?

1. Vitamin B6

Scientific research has shown that Vitamin B6 can increase fat burn by helping the body use more stored glycogen as an energy source. It also improves the way your body uses carbohydrates, so they’re less likely to be held as fat.

2. Glucomannan

Countless studies have linked glucomannan or konjac root extract to weight loss and diet control. Science has shown it significantly reduces hunger and cravings.

3. Capsimax®

This is a concentrated version of the thermogenic chili pepper ingredient we’re used to seeing in natural fat burners.

4. Green tea extract

Green tea has been linked to weight loss in several studies and contains proven thermogenic compounds called catechins.

5. Chromium

This ingredient contributes to improving the way your body uses and stores the carbohydrates you consume, so you store less fat.

Ingredients Amount per serving
Vitamin D31000IU
Vitamin B64mg
Vitamin B1210mcg
Green Tea Extract500mg
Cayenne Pepper Extract100mg
Black Pepper Extract5mg

How to take Hourglass

The manufacturers say to take one capsule, three times a day at mealtimes.

We’d slightly alter this and recommend you take the capsules just before you sit down to eat. This gives the appetite suppressant, glucomannan, time to expand in your stomach so you’re less likely to overeat at mealtimes.

We’d suggest using this pattern:

  • First capsule 30 minutes before breakfast
  • Second capsule 30 minutes before lunch
  • Third capsule 30 minutes before an evening meal

Hourglass price

  • $50/£30 per bottle 
  • $100/£60 for two bottles
  • $150/£90 for three bottles + one free bottle + free delivery
  • Buy one get one free offer currently in progress

What are people saying about Hourglass?

On their website, this is called they claim to have created an ‘intelligent, hype-free women’s fat burner’.

True to their tag-line, there aren’t many reviews of Hourglass out there. They don’t have any testimonials on their website, but the ones we found online were generally positive, both about the product and the transparent approach toward selling the product.

At the time of writing, this is a relatively new product to the fat burner market, so we will update when there are more personal reviews available. 


  • Caters to the dieting needs of women
  • Enhances results of a healthy diet
  • Completely natural ingredients
  • Low risk of side-effects
  • Stimulant free
  • The current buy one get one free offer is incredible value


  • More expensive than most
  • No added stimulants if you prefer a kick


After review, we found this to be a very effective fat burner for women. It’s clear that careful consideration has gone into making this a powerful, female-friendly formula.

The combination of powerful ingredients within this supplement work together to provide a support system for female dieters. It’s well dosed and contains a number of our favorite ingredients, which are all backed by research.

Although Hourglass doesn’t contain caffeine anhydrous, we think this makes it suitable for some many women. It’s this attention to their target consumer that makes Hourglass suitable to for females.

Although it’s not the most expensive fat burner supplement we’ve reviewed, it is at the upper end of the spectrum. However, it is worth bearing in mind that the quality of the supplements within this stack is very high.

Limited buy one get one free promotion

We’re not sure how long it will last, but they’re currently running a buy one get one free deal. There are also plenty of ways to get a free bottle if you’re looking to buy multiple products to last you for a few months. We think this offer is great value, so it’s worth having a look.

3) Hunter Burn

Hunter Burn Fat Burner

Compared to the other formulas on this list, Hunter Burn is a very different beast.

This supplement is designed for and advertised to appeal to an affluent customer, who’s looking for the very best product on the market. Hunter Burn claims to be just that.

Hunter Burn boasts only high-grade ingredients and says it will make you look and feel better – through weight loss results. It claims to do this by helping you burn fat, whilst avoiding muscle depletion, dulling hunger cravings and giving you more energy while you’re on a calorie-restricted diet.

Initially, we were skeptical. Burn is missing a key fat burner ingredient – caffeine.

Although this defies traditional fat burner wisdom, upon a thorough SpotMeGirl review, we found Hunter Burn really can deliver – up to a high standard too.

Read on to discover why Hunter Burn is one of our favorite fat burners for women.

What’s in Hunter Burn?

1. Konjac Root Extract

Science shows konjac root extract, or glucomannan expands when it hits your stomach. This makes you feel fuller and therefore suppresses appetite, so you feel less inclined to snack or over-eat.

2. Vitamin D3

Although an unusual addition to a fat burner, after research, we found the vitamin is linked to fat loss. It also helps to maintain muscle, which is key to increasing metabolism and maintaining healthy body composition.

3. Matcha Green Tea

Science shows this popular form of green tea us up to three times more powerful than other well-known strains and offers extremely potent thermogenic properties.

4. L-Theanine

L-theanine is widely known for creating a sense of focused calm. Scientific research has also discovered it can reduce fat build-up and improve your ability to resist hunger cravings.

5. White Kidney Bean Extract

If the konjac root doesn’t do its job, the manufacturers of Hunter Burn have created an additional buffer for damage control. This is a carb-blocker, which reduces the amount of carbohydrates you absorb when you eat them.

6. Cayenne Pepper

This ingredient is a well-known thermogenic, common in effective fat burners. It boosts your metabolism and gets your body working hard to burn calories faster.

[Related Article: Read our full Hunter Burn review here]

IngredientsAmount per Serving
Vitamin D3 (as Cholecalciferol)3000IU
Konjac Root Extract (Amorphophallus konjac) (Standardized to 90% Glucomannan)3000mg
White Kidney Bean 20:1 Extract (Phaseolus vulgaris)500mg
Matcha Green Tea (Camellia Sinensis)200mg
Cayenne Pepper125mg

How to take Hunter Burn

Don’t exceed the recommended amount and don’t miss a dose, otherwise you could risk lowering the effectiveness of the supplement. As this formula contains an appetite suppressant, it’s essential you plan your dosage around the meals you’re eating. We suggest you follow this pattern:

  • Two capsules, 30 minutes before breakfast
  • Two capsules, 30 minutes before lunch
  • Two capsules, 30 minutes before dinner

Hunter Burn price:

  • $75/£55 for one bottle
  • $150/£110 for two bottles
  • $225/£165 for three bottles + one free bottle + free delivery 

What are people saying about it?

At the time of writing, Hunter Burn is relatively new to the market, so reviews and testimonials can be difficult to come by.

There are currently a few available on the website, however we’d like to see more that will come with time.

We’ll update our review as the product settles in to the market.


  • Supports all stages of the fat loss process
  • Gives you the tools to stick to a diet
  • Promotes healthy fat loss
  • Completely natural formula
  • Low risk of side-effects
  • Transparent formula, free of proprietary blends


  • One of the most expensive fat burners on the market
  • No added caffeine if you prefer a bigger boost 


Although the supplement profile looks a little different to others, the intelligence of this formula combined with the potency of the natural ingredients puts Hunter Burn right up there as one of our favorite fat burner supplements.

The formula is entirely natural, very well dosed and carefully crafted to support all stages of the fat loss process.

The area where this product falls down slightly is the price. It’s a premium product and the price tag of $75/£55 reflects that.

However, we still believe Burn is great value for money, but we know the price may not make it the best option for most people.

*Individual results may vary. Please speak with your doctor or physician before undertaking any new weight reduction, supplement, or exercise regime

4) Leanbean Fat Burner

Leanbean Fat Burner

In fourth place is a specifically female fat burner, Leanbean.

Originally designed to give female fitness models a helping hand with their fat loss phase, it’s grown in popularity both for athletes and normal women looking to drop a few pounds.

It comes with an all-natural profile and claims to be completely tailored to women and their physical make-up to maximize results.

As women who’re very familiar with the supplement industry, we’ve seen this claim a hundred times over, without much substance to back it up. True enough, women have very different needs to men when it comes to sticking to a diet, but we’re very aware that many manufacturers simply change their packaging and call it a female formula.

Leanbean isn’t like this. After a SMG review, we’ve found that they’ve really done their research. They’ve created an intelligent supplement profile that should support women with their unique needs throughout the dieting process.

Read on to discover what makes Leanbean such a high-quality fat burner for women.

What’s in Leanbean?

1. Konjac Root Fiber

Also known as glucomannan, science shows konjac root is a powerful appetite suppressant. As a natural fiber, it works by expanding in the stomach, ultimately making you feel full. This is essential for women, as cravings can often mean the end of a diet for us.

2. Turmeric

In this mix, the makers of Leanbean have used the natural spice turmeric as a powerful thermogenic. This gives your metabolism a boost, so you burn more calories.

3. Garcinia Cambogia

This clever natural ingredient is proven to help your body naturally produce serotonin, which can help to suppress your appetite and kick cravings to the curb.

4. Green Coffee

Before they’re roasted, your coffee beans are green and packed with antioxidants and chlorogenic acid. These are scientifically shown to reduce fat absorption and lower blood sugar, along with giving you an energy boost from the caffeine within the beans.

5. Green Tea Extract

We’re very familiar with green tea in fat burners. Science has proven it contains catechins that help to increase your metabolism and boost your ability to burn fat.

Raspberry Ketones8mg

How to take Leanbean

Leanbean manufacturers advise you to take one capsule four times a day to get the best results.

As there are appetite suppressants in Leanbean, it’s always best to take the supplement before you eat. We recommend you take the capsules in the following pattern:

  • One capsule 30 minutes before breakfast
  • One capsule 30 minutes before lunch
  • One capsule 30 minutes in the afternoon
  • One capsule 30 minutes before your evening meal

Leanbean Price

  • $59/£39 per bottle
  • $118/£78 for two bottles
  • $185/£117 for three bottles + one free bottle + free delivery

What are people saying about Leanbean?

Overall, we found Leanbean to be well received by a lot of women looking to lose weight.

When accompanied by a calorie-restricted diet and exercise, many women claim Leanbean is key to their weight loss success.

From what we’ve seen, those who’ve reviewed it say it’s helped to subdue cravings, boost energy and even help to keep their mood high throughout the process.

Of course, we’ve found a number of reviews that claim it did nothing, however without understanding the circumstances of these individuals, we can’t say where the supplement failed them.

When looking at reviews and testimonials, our overall impression of Leanbean was a good one.

  • Uses only natural ingredients
  • Intelligent formula that addresses women’s issues
  • Completely safe
  • No proprietary blends
  • Backed by science


  • More expensive than other similar products
  • Some ingredients slightly under-dosed


When it comes to female-focused fat burners, Leanbean holds its own as one of the most effective on the market.

There are so many women-focused products out there that sell the dream but have very little proof to back it up. It was refreshing for us to find a female-centric fat burner that actually works.

Leanbean is a very intelligent formula that addresses the issues that women everywhere face when it comes to losing fat. They’ve used a range of natural appetite suppressants, powerful thermogenic and energy boosters to keep you on track and support a healthy weight-loss diet.

The value for money is good, although this supplement is still not the cheapest available at $59/£39. Having said that, it’s a premium product that should deliver.

Our main drawback with Leanbean is that it contains a large amount of ingredients, over just four pills a day. This means that a few ingredients, including the essential glucomannan, are slightly under-dosed.

*Individual results may vary. Please speak with your doctor or physician before undertaking any new weight reduction, supplement, or exercise regime

5) SPORT Fat Burner

Performance Labs Sport Fat Burner

Hailing from one of the most trusted labs in the world of supplements is Performance Lab’s SPORT Fat Burner.

As part of the SPORT range, the creators claim it’s designed for performance, to accompany an active lifestyle.

It apparently does this by raising metabolism, supporting muscle, increasing results from fasted training and helping you control hunger.

Although these benefits make SPORT Fat Burner sound like the ideal candidate for best fat burner for women, we were initially concerned about the abilities of such a limited formula.

We’re missing a number of key ingredients we know make top-quality supplements. For example, we know glucomannan is the most effective natural appetite suppressant available. We also know that caffeine can be a powerful thermogenic and energizer for a fat burner. The SPORT formula is lacking both these ingredients.

Despite this, we found SPORT Fat Burner to be a top contender. Read on to find out how it managed to secure its place in our list of the best fat burners for women. 

What’s in SPORT Fat Burner?

1. HMB (ß-Hydroxy ß-Methylbutyrate)

This is a metabolite of the branched chain amino acid leucine and has been shown to optimize the results of fasted training.

HMB does this by preventing the degradation of muscle during fasted training. It stops muscle-damaging enzymes and promotes muscle growth.

2. Coleus Forskohlii

This root herb contains an active ingredient called Forskolin. It has been shown to promote the activation of cAMP, which helps to regulate metabolism, thermogenesis and muscle growth.

3. Cayenne Pepper Extract

We’re very familiar with this ingredient. It’s a regular in fat burners, due it’s thermogenic properties.

Cayenne pepper extract has been proven to increase metabolism and enhance energy expenditure so you burn more calories than you normally would. It’s also proven to improve fat oxidization, so your body draws on fat cells for fuel.

While this is a very potent ingredient, the serving size is small compared to other supplements on this list.

4. Black Pepper Extract

This helps to optimize the thermogenic benefits of the other ingredients, and slows adipogenesis, which is the formation of new fat cells.

Ingredients note: We’d like to highlight that an appetite suppressant is often a game-changer for women in a weight loss diet. It helps to control cravings and control portion sizes. With this in mind we were disappointed to find SPORT didn’t contain any appetite suppressants. However, as a stimulant-free supplement, it might be more suitable to some women.

Ingredients Amount per serving
HMB (ß-Hydroxy ß-Methylbutyrate)250mg
Coleus Forskohlii1000mg
Cayenne Pepper Extract50mg
Black Pepper Extract2.5mg

How to take SPORT Fat Burner

We always recommend following the recommendations of the manufacturers to ensure effectiveness and safety.

Performance Lab suggest you take 2-4 pills 15 minutes before your workout.

Note: This is a little unorthodox for a fat burner supplement. In order to maintain thermogenesis, we’d rather see this taken at intervals throughout the day. Instead SPORT offers a spike, which could limit the effectiveness of some of the ingredients.

SPORT Fat Burner price

$50/£40 for one bottle

Note: The manufacturers recommend you take between two and four capsules per daily serving. With 60 capsules in a bottle, it should last a month with just two a day. However, if you find you need four, you’re cutting your number of servings in half, which will significantly affect the overall value of the supplement.

What are people saying about it?

As a well-established supplement and company, Performance Lab’s SPORT Fat Burner has plenty of reviews online.

Our impression of the supplement from reviewing testimonials was overwhelmingly positive. Many enjoyed the fact this supplement is stimulant-free, and supports the effects of fasted training.

Similar to our findings, some identified the lack of appetite suppressants as a drawback with the formula.

Others like the fact that fewer ingredients make room for higher serving sizes.

Overall, we found this to be a popular fat burner with those who’ve tried and tested it.


  • Completely natural formula
  • High-quality ingredients
  • Safe to use
  • No proprietary blends
  • Backed by science
  • Stimulant free


  • No appetite suppressants
  • No caffeine if preferred
  • Low thermogenic levels


While this product might not be the best all-rounder, it definitely offers a range of benefits that could increase your ability to cut fat.

Its ability to enhance results from fasted training will suit many women very well. However, the lack of appetite suppressants or stimulants might not make it the best option for the majority.

Overall, those who tried it as it’s meant to be used were happy with the results, the formula is well served and uses high-grade ingredients that are well-researched and backed by scientific studies.

One drawback is the pricing. If you stick to two capsules daily the value is very good for SPORT Fat Burner. However, if you decide you need the additional two, the value is halved. This is worth considering, especially if you’re looking for more a kick from your thermogenic ingredients.

On the whole, if you’re into fasted training, this could be an excellent fat burner for many women.

Best fat burner ingredients to look out for

In the world of fat burning, there are a few ingredients that are superior to others.

By this we mean they generally have better scientific backing, are safe and are front-runners when it comes to potency.

To help you spot a top-quality fat burner for women, we’ve listed out all the very best ingredients and the benefits they offer. From thermogenic’s to appetite suppressants, these are the elements you want to see on a supplement facts label.

Caffeine Anhydrous

The stimulant can raise your metabolic rate through thermogenesis, which can help your body burn more fat, even while at rest. It also helps you to stay energized on a low-calorie diet, so you can work out and maintain an active lifestyle.

Nootropic elements of caffeine can also help you to stay focused and mentally alert even when energy levels are low.

Green Tea Extract

The catechins within green tea release a powerful thermogenic, which raises your metabolism, targets fat and boosts your daily calorie expenditure. It also comes with a small hit of caffeine, which can heighten energy levels.

Glucomannan (Konjac Root)

This a soluble fiber that expands into a gel-like consistency once in the stomach. When this happens, it creates a feeling of fullness. This is essential to a good fat burner, as it helps you to stay in control of your diet by reducing cravings and limiting portion sizes.

Glucomannan is the sign of a quality fat burning aid that takes every stage of the weight loss process into account.

Cayenne Pepper

Not only is this ingredient packed with essential vitamins that support overall well-being, but cayenne pepper is also a powerful thermogenic. It raises your overall metabolism, whilst enhancing your body’s ability to use fat as an energy source too.

White Kidney Bean

This is the only known natural carb blocker. If you slip up on your diet and opt for a cheat meal, it reduces the amount of carbohydrates your body absorbs. It’s a form of damage control.

Again, this is a very intelligent addition to a fat burner, and provides a weight loss support system rather than just heightened calorie burn.


Do fat burners work?

Fat burner supplements are designed to complement a calorie-restricted diet and active lifestyle. When used in these particular conditions, they can help to support and enhance results. However, when used alone they aren’t enough to help you lose weight.

What are fat burners?

These are supplements used to help heighten weight loss results from a reduced-calorie diet and regular exercise. They are made up of a range of ingredients that have been linked to improved fat loss and diet management.

Are fat burners safe?

The majority of natural fat burners are generally safe to use. However, those with high caffeine content may lead to side effects if you don’t account for the additional stimulants in your diet or if you are pregnant.

Fat burners that use synthetic ingredients or contain proprietary blends can be deemed unsafe as you can’t know what ingredients are used, how they’ll affect your body or, where proprietary blends are concerned, how they’re dosed. We’d recommend avoiding these supplements at all costs.
