Well, here’s where fat burners come in; they can really fire up your metabolism, so you don’t have to blame your ‘bad genetics’ anymore, and finally achieve that sexy, slim figure you’ve always worked towards.

Ultimately, this guide will save you from the headache of trying to choose from the hundreds of fat burners out there. Most importantly, we want to save you from being fooled by pink-packaging targeting women for quick sales.

  • What are fat burners?

  • Best fat burner for women

  • Key Tips for fat loss

What Are Fat Burner Supplements?

Fat Burner Supplements contain numerous thermogenic ingredients that are specifically shown to help raise your fat burning potential. If you choose the right product, it’ll help provide certain benefits that allow your body to melt fat at a faster rate than you would naturally.

Here’s how fat burners work:

  • Boost your metabolism
  • Suppress your appetite
  • Raise your energy levels

Listen, it’s important that you know that fat burner supplements aren’t miracle pills. They give you that extra ‘kick’ to help you lose body fat, but you still need to continue working hard in the gym and on your diet too.

Ultimately, you won’t achieve that booty poppin’ figure by eating junk food sat on the sofa. But if you really do put the effort in, fat burners will help you see results, faster.

However, as you know, there are hundreds of fat burners to choose from…this is why we’ve mentioned you need to choose the ‘right’ product.


 How To Choose The Best Fat Burner

If you simply choose the first fat burner you see on the shelves, there’s a very high chance you’ll end up with an ineffective product. This will burn a hole in your wallet, but not your body fat.

You might be here because you’ve already have wasted money on an ineffective fat burner. Well, the good news is that you’re doing the research so you don’t make that mistake again, honey!

Fortunately for you, our team is compromised of expert nutritionists and fitness experts, so we know a thing or two about nutrients in fat burners. As a result, we’re going to provide you with the information you need, to ensure you chose a fat burner that actually works, every time.

Best Fat Burning Ingredients

This is important. Think about the ingredients in fat burner supplement as the engine in a car; companies can make it look fancy on the outside, but if the engine is rusty, then it won’t be very useful.

Well, it’s exactly the same with supplements. Companies often try to fool you into thinking their products are better than they really are – especially fat burners aimed at women.

They’ll print things such as ‘clearer skin’ and other things to try and make you believe they’re better than non-gender orientated supplements.

For this reason, we advise you to avoid most fat burners marketed specifically towards women. But if you do decide to choose a fat burner for women, then it’s essential that you check which ingredients have been added to them.

Here are the best fat burning ingredients:

Green Tea Extract 


There’s a reason why many people drink green tea, and why Asian countries have been consuming green tea for centuries – it works.

What does it do? Well, studies have proven that Green Tea benefits almost every organ in your body, and most important, helps you burn fat.

This is because Green Tea is a tried-and-tested thermogenic nutrient that’s shown to raise your metabolism, due to containing high amounts of catechins [1].

Now, it would be easy to say ‘i’ll just drink 7-8 cups of green tea per day instead of consuming fat burner supplements.’ However, this isn’t ideal, especially if you’re sensitive to caffeine.

Ultimately, consuming green tea extract in fat burners won’t increase your caffeine intake for the day, as the extract is basically concentrated catechins.

For this reason, we consider Green Tea Extract to be a key addition to fat burner supplements and one you should definitely look for when making your decision.

Cayenne Pepper Extract 


This is one ingredient that you probably already know works, even without looking at scientific studies.

If you’ve eaten chilies before, you know how it can make you sweat and probably result in you asking for a cup of milk to cool down your mouth!

Well, this ability to raise your body temperature is exactly what raises your metabolism; as your body works harder to cool itself down and regulate its temperature, this process burns extra calories – promoting fat loss [2].

Ultimately, you can add chilies to every meal you consume, but if you don’t like spicy foods, this is a problem. For this reason, we believe that consuming higher amounts in supplements is a much easier option, and you’ll be more likely to consume the optimal amount of capsaicin needed to promote fat loss too.

In case you’re wondering, capsaicin is the nutrient contained in Cayenne Pepper Extract that’s responsible for its ‘spice’ and ability to promote fat loss.



Many people are often told that green vegetables are healthy, without any further explanation why.

Well, it’s because green vegetables, especially broccoli, contain Chromium; this essential trace mineral has proven to increase insulin sensitivity, which reduces the effects of sugar and carbohydrates [3].

As Chromium is able to prevent sugar spikes, this effectively helps your energy levels stay stable, and also encourages your body to use body fat as fuel too.

Not only that, Chromium has also shown to be an effective appetite suppressant too [4] – which will help you lower your calorie intake and stay away from junk food.

For this reason, it’s a good idea to add green vegetables to your meals and consume Chromium in supplements. This will give yourself the best chance of melting body fat, quickly.

Best Appetite Suppressant For Fat Burners

We believe that appetite suppression should be a key benefit from taking all fat burners. But the bad news is that not many actually deliver this effect.

Why? Because most fat burner supplements don’t contain the necessary nutrients.

Ultimately, by eliminating hunger cravings and keeping you more satisfied between meals, you’ll be less likely to reach for candy bars or junk food; in effect, this reduces your calorie intake, allowing you to achieve that booty poopin’ bikini body faster than ever.

We mentioned that Chromium can have an appetite suppressing effect. But there’s a better option to ensure you experience this benefit.

For this reason, we’ll show you our favorite nutrient when it comes to suppressing your appetite in fat burner supplements below:



It’s only recently that Glucomannan has hit the spotlight in western countries. It’s now being sold in Asian supermarkets across the USA & UK in the form of ‘Shirataki noodles’, and western companies are even selling this ingredient in ‘low calorie’ noodles and rice forms too.

Basically, this ingredient is also known as Konjac Root; it’s an extremely low-calorie fiber that safely expands in your stomach once consumed; this is why it helps eliminate hunger cravings and suppress your appetite.

Glucomannan has been consumed in Asian countries, especially Japan, for decades. So it’s about time western countries started to learn about its benefits (suppressing your appetite and improving the health of your digestive system) [5].

Ultimately, we try and include Konjac Root in our meals as we enjoy its unique taste. But it’s much easier (and cost-effective) for you to consume Glucomannan as part of a fat burner supplement.

Best Fat Burners For Women 2021

Now that you know the best fat burning ingredients to look for, you’ll have a better idea of how we came to our decision. But trust us when we say that not many fat burners contain the right nutrients in effective dosages.

But don’t worry girl, we’ve got your back.

For the past couple of years, we’ve been trying countless fat burner supplements, and after being disappointed by just as many, we’ve finally found some fat burners for women that deliver on their promises.

Check it out:

Instant Knockout

Made by specialist supplements company, Roar Ambition, Instant Knockout was originally created to help boxers, MMA fighters and fitness models lose body fat and perform at their best.

After experiencing great success with internationally published fitness model, Alexia Clark (known as ‘The Queen of Workouts’), as well as notable UFC legends such as Diego Sanchez & John Dodson, Instant Knockout was made available to the public.

Ultimately, after seeing many female success stories, we had to try Instant Knockout for ourselves – and we’re glad we did.


Key Benefits

  • Tone Up Without Bulking Up – Lose fat in unwanted areas of your body and tone up your stomach, arms, legs, and glutes without risk of becoming a ‘she-hulk’.
  • Bikini Beach Body Figure – Look even better in your favorite clothes and especially on holiday in your booty poppin’ swimsuit!
  • Feel Confident In Your Own Body – Never feel embarrassed about your body again, once you sculpt the figure most women dream of having.
  • Finally, See Results From Your Efforts – Don’t let your hard work go to waste again, and realize your fitness goals faster.


  • Premium price-tag – Instant Knockout costs more than ineffective fat burners, but you always pay more for higher-quality clothes and make-up, right?
  • Only available on the official website: – We prefer online shopping anyway, so this wasn’t a problem for us.

How It Works

We mentioned that the ingredients are the heart of a product. Well, Instant Knockout works, because it’s been carefully formulated using tried-and-tested fat burning nutrients.

With optimal dosages of Green Tea Extract, Cayenne Pepper, Chromium, as well as Green Coffee Bean Extract, this fat burner will allow you to burn body fat in unwanted areas.

Not only that, as it contains a safe and effective dosage of Glucomannan, you won’t be tempted to reach for your snack drawer between meals. Ultimately, this makes it easier for you to lower your calorie intake, which leads to you achieving your that sexy, slim figure you’ve always worked towards, faster.

During the months we used Instant Knockout, it was one of the few fat burners that delivered on its claims and didn’t cause any side effects. For this reason, it’s become our favorite fat burner for women this year.

Other People’s Results

When looking to see how effective fat burner supplements are, we like to check how it worked for other people. And there was no shortage of success stories with Instant Knockout, which seems obvious since it’s been used by professional fitness models.

Anyway, we’ll show you some of our favorite progress pictures from past Instant Knockout customers below:


“I decided to try instant knockout after trying several other fay burners and after tons of research, I took the leap. Boy am I glad I did!

“I’ll admit the first couple of days I was on such a high it was hard to sleep. After, I eventually got used to it and continued with my weight training. Usually, i eat pretty well so i really didn’t change my diet.

“I had increased energy, stopped eating out of boredom and felt so much stronger at the gym. I was on fire!

“First, I tried it for 3 months and bought another 3 months worth. Even after the first 2 weeks on Instant Knockout I saw results. I was in awe!

“If you are contemplating on trying it out I highly recommend it. Instant knockout has helped me kickstart my journey and I am now a bikini competitor. I can’t believe I was once 25kg heavier and now able to be on stage!

“Thank you Instant knockout for bringing out this product. You have really assisted me in reaching my goals.”

Key Benefits

  • Feel less hungry between meals – Containing an optimal dosage of Glucomannan, you’ll feel full for longer after eating so you stay away from sugary snacks.
  • Stable energy levels even while cutting carbs & calories – With a very sensible dosage of Guarana Seed Extract, you won’t feel fatigued like you normally would when starting a calorie-deficient diet.
  • Improved mood and self-confidence – The Vitamin D3 in Hourglass will help you feel happier, and you’ll feel more confident knowing your hard work is actually resulting in that toned look you’ve always wanted.


  • Aimed at only women – As we’ve mentioned, we don’t see the need for ‘female only’ supplements (nutrients such as Green Tea Extract benefit men and females equally). But we understand that sometimes women want a more ‘feminine’ looking product when possible.
  • No free shipping unless you spend $150 – We prefer free shipping with all orders (who doesn’t?!), so we were slightly disappointed to see that 1 bottle orders don’t come with this.
  • You can only buy from

Quick Summary

You’ll be able to see that this is a fat burner aimed at women. You might be confused about this, as we’ve said throughout this page, and our reviews, that we don’t agree with gender-specific supplements.

While we still don’t think they’re necessary, Hourglass is the best of the ‘female only’ fat burners; it contains all the right ingredients that are proven to make your fat burning journey easier. In fact, Hourglass includes many ingredients that are seen in Instant Knockout, so it’s great to see more companies doing their research when formulating their products.

We’re just happy that Hourglass doesn’t come in any pink packaging like the other ‘female only’ supplements on the market. To be honest, it’ll be just as beneficial for men, so if you prefer a more ‘feminine’ looking fat burner, Hourglass might interest you more than Instant Knockout.

How To Stay Safe From Side Effects

Staying safe from side effects when consuming fat burner supplements is equally as important as choosing an effective product.

Why? Because there’s no point spending money on a supplement designed to give you a positive ‘kick’ on your fat burning journey if it’s going to cause side effects.

It’s important to know that there are safe and effective fat burners for women out there, so there’s no need to settle for anything less.

But to ensure you stay safe when choosing a fat burner supplement, we’ll show you the main reasons why these products can be potentially harmful below…

Avoid Overloads of Stimulants

Companies adding too much caffeine into their products is probably the biggest cause of side effects when taking fat burners.

Think about it; when you consume too much coffee, you’ll suffer from jittery side effects.

Well, it’s exactly the same when you consume large dosages of caffeine in supplements. But we’re not saying avoid Caffeine altogether, as we believe it’s a key addition to fat burners when dosed correctly.

For this reason, we advise you to consume under 100mg caffeine per capsule serving in fat burners.

Ultimately, this advice will help raise your energy levels while you’re cutting calories and carbs from your diet – while keeping you safe from jittery side effects.

Avoid Bitter Orange Extract

Also known as ‘Citrus Aurantium Extract’, this is one of the worst ingredients you can find in fat burner supplements.

Why? Because Bitter Orange Extract is commonly reported to cause side effects, due to containing high amounts of Synephrine.

Basically, Synephrine is a chemical that’s been banned from use in supplements, but companies are able to pass through a legal ‘loophole’; as they’re not directly adding Synephrine, they’re not breaking any laws.

So why do companies add this nutrient? Well, Bitter Orange Extract has shown to slightly promote fat loss in studies, but it’s simply not worth the risks to your health.

Ultimately, we believe that Bitter Orange Extract will become a banned substance in the future anyway. But until then, we advise you to choose fat burners containing safe nutrients instead of Bitter Orange Extract, to stay safe.

Avoid Yohimbe Bark Extract

We just mentioned that Bitter Orange Extract contained high amounts of a banned substance.

Well, it’s exactly the same story with Yohimbe Bark Extract; this ingredient contains high amounts of Yohimbine, which has been banned from direct use in supplements.

Basically, companies are also able to pass legal loopholes, as Yohimbe Bark Extract hasn’t been banned from use yet. However, we believe that it’s only a matter of time, due to this ingredient being commonly reported to cause numerous side effects.

For this reason, we advise you to avoid Yohimbe Bark Extract too, for your own safety.

Avoid Proprietary Blends

You might not know what these blends are, but you’ve probably seen them on the ingredients list of supplements before; basically, company’s hide dosages of nutrients in blends titled with fancy names (eg. Energy Elevation Blend), meaning you’re not shown the exact amounts of ingredients in their products.

See an example below if you’re still unsure:


Why is this a problem? Well, we’ve already mentioned that consuming big dosages of stimulants can lead to jittery side effects, and you never know how much caffeine you’re consuming if it’s added to a proprietary blend.

Simply put, that means you won’t know whether you’ve consumed too much caffeine until it’s too late.

For this reason, we advise that you avoid supplements containing these proprietary blends. Instead, choose products that clearly list the exact dosages of each ingredient, allowing you to see how safe and effective it is before you consume it.

Key Tips For Fat Loss 

To make sure you succeed on your fat burning journey, we won’t let you leave without giving you some tips to help you along the way.

As we mentioned, fat burners aren’t miracle pills that you consume while sitting on the safe eating junk food. You still have to work hard in the gym, and follow a clean diet too.

Eat Under Your Maintenance Calorie Limit

If you want to lose body fat, it’s important that you calculate your maintenance calorie limit (what’s officially known as your BMR – Basal Metabolic Rate).

The most reliable method of calculating your BMR is by using the ‘Harris Benedict Equation’, which we’ll show you below:

  • Women’s Basal Metabolic Rate = 655.0955 + (9.5634 x weight in kilograms) + (1.8496 x height in centimetres) – (4.6756 age in yrs)

We know what you’re thinking, this is quite a complicated equation to figure out, especially if you hate crunching numbers like us…For this reason, we’ve found an easy-to-use calorie calculator you can use online here.

Ultimately, if you don’t eat under your maintenance calorie limit, you won’t lose any weight – that’s a fact. But the problem is, even if you do this, your genetics usually determine the rate at which you lose body fat – which is why we recommend fat burners to speed up the process.

As we mentioned, fat burners that suppress your appetite also help you keep your calorie intake down, which helps you stay under your maintenance calorie limit.

Perform HIIT & Lift Weights

Don’t worry, we’re not going to tell you to begin lifting seriously heavy weights. However, weight lifting has proven to help you burn calories efficiently. Which will help you sculpt your dream bikini beach body [6].

In fact, if you want a toned booty, then your best option is to begin performing squats in the gym; every fitness model will agree that this exercise is the best at helping you tone-up your glutes and legs.

Not only that, we don’t want you wasting hours of time on the cycling machine or treadmill either.

Instead, you’ll spend your time in the gym more wiser by performing HIIT (High-Intensity Interval Training); this is where you sprint for a short period of time, then rest before beginning again.

For example, you could sprint for 10 seconds, then rest for 50 seconds, before starting the process again. Studies have proven that HIIT burns equally as many calories as hours in on the treadmill at a slower pace, as well as delivering an ‘afterburn’ effect (keeping your metabolism slightly raised even hours after your workout) [7]. Not bad, eh?


We’ve shown you the main things you should look out for, as well as avoid when choosing a fat burner supplement; this should give you a head-start on your search for the best fat burner for women.

It’s important to remember that the ingredients in these products determine how safe and effective they are. So we recommend checking their ingredient lists before consuming them – to stay safe from unwanted side effects.

Also, remember that there’s no such thing as ‘female only’ fat burners!

If a company tries to tell you it’s formulated for women, they’re lying and are usually just trying to make a quick buck, and their product will only result in a waste of cash.

Why? Because there’s no such thing as ‘gender-orientated’ fat burning ingredients; think about it, is green tea or cayenne pepper ‘men only’ nutrients? No, studies have shown that they’re equally as effective for both men and women.
