The Best Fat Burners for Women in 2021

Here they are, our 1-2-3 podium winners…

#1 Overall – Hourglass Fit

Leading the way is women’s only fat burner – Hourglass Fit. This highly targeted product looks sleek and impressive, but how does it hold up to scrutiny?

Hourglass Fit

We’ve carefully picked Hourglass Fit’s formula apart to see if it’s as smart as they say.

Overall, we were very impressed with its ingredient profile.

It contains a completely natural, vegan-friendly formula with ingredients that work together to ‘attack’ fat from multiple angles. It’s designed to:

  • Boost your metabolism
  • Eradicate food cravings
  • Reduce fat storage
  • Give you that leaner, confident look

Every ingredient in the formula is top of the line and is dosed clinically to help maximize your results from training and eating healthily.

Official Website:

Although we saw thermogenics and appetite suppressants in the mix, there are no stimulants in Hourglass Fit, which made us intrigued by how it gives so much energy.

However, since a lot of women actually prefer stim-free formulas, it could be a win-win.

Here’s what’s inside the fat burner:

The Ingredients

  1. Vitamins B2 and B6 – Shown to help the body become more efficient at using stored glycogen as energy, along with improving carbohydrate metabolism, making carbs less likely to turn into fat. [1]
  2. Glucomannan – The best natural appetite suppressant science currently knows of. It’s been shown to significantly reduce hunger. Hourglass Fit contains 3000mg per serving, which is the clinically proven amount needed to prevent food cravings. [2]
  3. Capsimax – This is a branded form of cayenne pepper. It triggers thermogenesis, a process where your basal metabolic rate increases. [3]
  4. Green Tea – It’s been linked to weight loss in numerous peer-reviewed studies and contains proven fat-burning compounds called catechins which are also anti-inflammatory and good for general health. [4]
  5. Chromium – Regulates blood sugar levels, improving how your body uses and stores energy from the food you eat. [5]
  6. 5-HTP – Natural amino acid that reduces symptoms of irritability and low mood and doubles up on Hourglass’ appetite suppression effects. [8]
  7. Zinc – An essential trace mineral that supports the immune system and metabolism. [9]

How to Use Hourglass Fit

According to the manufacturers, you should take one capsule, three times daily with your main meals.

However, perhaps it’s best to take it before meals to allow glucomannan, the appetite suppressant, time to swell in your stomach so you won’t overeat at meals.

Our Thoughts

Hourglass Fit starts working about 4 weeks into the supplementation. We think it is an incredibly effective product.

Pairing it with a varied, calorie-restricted meal plan and a 3-time-per-week workout program is the way to see the best results.

Overall, we felt the best thing about Hourglass was how good users feel on it. There was a definite increase in willpower and mental focus, and so you will naturally be in control of your cravings, and stick to your diet throughout the whole trialing period. On top of this, you should feel energized enough to visit the gym regularly despite sometimes being low on calories!

The main benefits you can expect from taking Hourglass Fit:

  • Great results in the mirror
  • A lot less snacking
  • Smaller meal portions and still feeling satiated afterward
  • Better gym sessions
  • Sticking to the diet without any issues

Completely natural and packed with healthful vitamins and plant extracts, Hourglass Fit is safe and unlikely to cause any side effects. We also like the fact that it didn’t add extra caffeine – Guarana provides a much smoother effect that energizes you, without the anxiety or jitters.


  • Meets the dieting needs of females
  • Enhances results of a healthy lifestyle
  • Completely safe, legal, and plant-based
  • Extremely low risk of side effects
  • Free of aggressive stimulants
  • Excellent reviews
  • Fantastic “buy one, get one free” offer


  • A bit more expensive than the competition

#1 Thermogenic and #2 Overall – Instant Knockout

Even though it was originally made for MMA fighters, we feel this is an ideal natural supplement and can be incredibly effective for women.

Instant Knockout CUT

Created by the highly established company Roar Ambition, this is a top-of-the-line product with a precise serving schedule.

We looked through many of the testimonials online and so many women say it’s helped them get to their weight loss goal.

After reviewing Instant Knockout for ourselves, we think it can help women get leaner in the following ways:

  • Boost metabolism
  • Give ample energy and focus to have better workouts
  • Increase feelings of satiation
  • Strengthen immunity and overall health with antioxidants

Instant Knockout’s 100% natural formula contains a very reasonable dose of caffeine that’s not too high for females and free of unwanted side effects.

See How Instant Knockout Works for Women:

We’ve seen plenty of similar statements with fat burners before, but after putting it to the test in our rigorous QC program we were very impressed to find it delivered in all departments – fat burning, appetite suppression, and mood and energy.

What’s in Instant Knockout?

  • Green tea extract – This is one of the most effective thermogenics on the market. An impressive 11 independent studies reported fat-burning properties in green tea extract.
  • Cayenne pepper seeds – Not only are these full of vitamins, they’re also effective at raising your basal metabolic rate.
  • Glucomannan – Also known as konjac root extract, it expands in your stomach and consequently reduces the risk of hunger-induced food binges.
  • Caffeine – IKO doesn’t have aggressive levels of caffeine like some fat burners do, but it’s still plenty to provide you with hours of clean energy and focus.
  • Vitamin B6 – A controlled clinical trial found that supplementing B6 can increase fat oxidation which directly contributes to weight loss.

How to take Instant Knockout

In terms of getting the most out of your fat burners, timing is everything. It’s a good idea to take IKO before you eat a meal, to allow the appetite suppressants in it to help you feel less hungry.

You should take one capsule of Instant Knockout, 4 times per day. So one in the morning on an empty stomach, one just before noon, one in the early afternoon, and the last one around 5 PM.

Our Thoughts

It’s not just the pros who’re getting the results from using Instant Knockout. We saw a massive number of positive reviews, indicating how well the supplement can work when coupled with the right lifestyle.

As for our personal thoughts, we found IKO to be a high quality product that can make some significant changes to appetite, motivation and overall energy levels.

All in all, it feels much easier to stick to your diet and commit to seeing every workout through – despite being in a calorie deficit. You also feel more motivated and less hangry.

Taking it with a healthy, calorie restricted diet also enables you to notice the difference in your body.

This is what you can expect from using Instant Knockout:

  • Noticeable fat loss
  • Less snacking
  • More focus and motivation to hit the gym
  • Smaller meal portions
  • Easier to stick to diet

This product doesn’t come with any kind of synthetic ingredients, and the amount of stimulants is low, so you shouldn’t worry about side effects. None of the users noticed any when taking Instant Knockout – simply keep your coffee and tea intake low throughout the day as this provides enough anyways.


  • Intelligent ingredient combination
  • Multi-pronged approach to burning fat and controlling diet
  • Completely natural and safe formula
  • Extremely low risk of side effects
  • Transparent label with every ingredient and its respective dose listed clearly
  • Backed by scientific research and nutritionists
  • Some of the best reviews online


  • Premium price range

  • Only available at

#3 – ShredCBD

Taking our third place is one of the most innovative fresh weight management and fat burning products on offer right now – ShredCBD.

What is ShredCBD?

ShredCBD uses the latest and most effective ingredients to help regular females and athletes shed down unwanted fat.

In addition to that, ShredCBD also significantly benefits women who do regular workouts as it’s one of the best natural performance and recovery products we’ve tested.

ShredCBD combines the power of hemp-derived CBD isolate with two other proven fat burning compounds to deliver a very effective method for you to cut back the pounds and help reveal a sleek and aesthetic physique underneath.

After reading other reviews online and trying it for ourself, we rounded up the overall conclusion on ShredCBD:

  • Boosts weekly weight loss using a blend of Green Tea and Garcinia Cambogia, and 40mg of CBD per capsule
  • CBD promotes fat browning [6]
  • CBD helps regulate cravings by interacting with your brain’s endocannabinoid system [7]
  • Reduces fatigue and makes it easier to fall asleep and wake up in the morning without feeling groggy
  • Mood and wellbeing improve, making it easier to see set goals through.
  • Reduces cortisol and makes you feel less stressed.
  • Super simple to use, 2 capsules per day before meals.
  • Fee delivery and our order came in 2 working days.

One downside for UK customers and others around the world is that ShredCBD is only available in the USA at the moment.

Our Thoughts

We loved reviewing ShredCBD and will be continuing to recommend it as an integral part of anyone’s daily supplement stack.

It brings impressive fat loss results, but what is even more impressive are the improvements to mood, focus, as well as sleep and recovery.

We were quite stunned with the whole package that this seemingly simple CBD formula can offer women and so had to put it on our top three.

CBD is stimulant-free too, which means you can take it at any part of the day to enhance your performance without any risk of side effects.

  1. I have gone through so many fat burner articles because I am looking for an active diet pill for my Mom. Thank you for this guide, I’m happy I found it now. I’m going with ShredCBD since it has no caffeine. Thanks again.

    • No problem Melissa. Hourglass Fit has very little caffeine from green tea. It’s worth giving it a try, unless you’re really sensitive. In which case, it’s best to stick to fat burners that don’t use any source of caffeine – such as ShredCBD.

  2. Hey, I just commented on your other post about Instant Knockout. I bought it for myself and later, for my wife. We are both extremely happy with the results. It’s the only one that has worked for me out of many that I trialed this year. Thanks.
