Finding a fat burner that works can be frustrating – but it doesn’t have to be. Get informed with this article and discover the leading supplements that work to boost your metabolism, elevate mood & energy levels, and curb nagging food cravings in an effective, natural, and safe way.

We’ve tried to make it easier for you by picking out the very best weight loss supplements on offer today.

From a genetic perspective, women tend to hold onto body fat more easily than men, making weight loss difficult.

Luckily, today we have natural compounds that have been shown to stimulate your body to get rid of excessive fat, along with boosting mental willpower & focus, and reducing the desire to snack on foods.

We’ve scoured the internet to find the safest, cleanest, and most effective fat burners that fit the female requirements to help you lose weight effectively.

After analyzing 100s of fat burners in the past years, we’ve narrowed it down to the top 3 picks for women specifically, using our own set of rigorous criteria.

Our Criteria

We didn’t use these supplements, but we analyzed their ingredients and compared them to the available scientific literature to get an accurate picture of how they will work for you.

A high-quality fat burner must tick the following boxes:

  • 100% natural ingredients that are backed by studies
  • Boosts metabolic rate
  • Real results and excellent customer testimonials
  • Esteemed brand reputation
  • Contain a safe dosage of caffeine for an additional energy boost

We avoid scam products that can lead to negative side effects and check the reputation of the company behind the supplement. The fat burner must produce visible results within 4-5 weeks of consistent usage.

Using this, we’re able to give you the answer to which products can stand up to the big names in the fat burner market.

The Best Fat Burners for Women in 2021

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

#1 Overall – Hourglass Fit

Leading the pack is women’s only fat burner – Hourglass Fit. The bottle looks sleek and impressive, but what results can it give you?

Hourglass Fit

We’ve carefully picked its formula apart to see if it’s as good as the reviews say.

Overall, we’re impressed by Hourglass Fit’s formula.

It contains an all-natural, vegan-friendly formula. Each ingredient works in synergy with others to “attack” fat from multiple angles.

Hourglass Fit helps you lose weight by:

  • Keeping your metabolism elevated throughout the day and night
  • Reducing fat storage
  • Blocking fat production
  • Eradicating food cravings

If you pair it with a calorie-controlled diet, Hourglass Fit is going to help you achieve that Hourglass figure; that is, a lean & toned look with a minimum of body fat.

Each ingredient in Hourglass Fit is top of the line in terms of effectiveness, clinical studies, and dosages.

While Hourglass Fit is free of stimulants, it still gives plenty of energy, which is surprising! This is a win-win as many women like to avoid stimulants altogether.

Here’s a look at the ingredients:

The Ingredients

  1. Vitamins B2 and B6 – these are shown to help our 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 – One of the best, if not the best science-backed natural appetite suppressants. Glucomannan has been shown to substantially reduce hunger by keeping you feeling full for longer. Hourglass Fit contains 3000mg per serving, which is the clinically studied amount suggested 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 to four daily with your main meals.

Our Thoughts

Hourglass Fit starts working about 4 weeks into the supplementation. It is a highly effective formula.

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 women feel while using 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

#1 Thermogenic and #2 Overall – Instant Knockout CUT

While Instant Knockout CUT was originally developed for professional athletes, the success of this fat burner has seen it released to the general public later on. Instant Knockout is incredibly effective for both women and men.

Instant Knockout CUT

Instant Knockout was developed by the highly respected Roar Ambition. It is a top-of-the-line product with a precise serving schedule.

We’ve gone through many testimonials on the internet and many women report impressive results from using IKO.

After checking Instant Knockout for ourselves, we can confirm that it helps you 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 your diet

This product doesn’t come with any kind of synthetic ingredients, and the amount of stimulants is not excessive, so you shouldn’t worry about side effects if you aren’t sensitive. Simply keep your coffee and tea intake low throughout the day as Instant Knockout provides enough anyways.


  • Intelligent ingredient combination
  • A 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

#3 – ShredCBD

Taking third place is one of the most innovative weight management and fat-burning products on sale today – ShredCBD.

ShredCBD takes advantage of the latest research in nutraceuticals by combining highly effective ingredients to help regular females and athletes alike shred down unwanted fat.

ShredCBD also works extremely well for women who do regular gym training as it’s one of the most potent natural performance & recovery supplements we’ve seen.

The supplement combines the power of hemp-derived CBD isolate with two other proven fat-burning ingredients to deliver a highly effective method for you to cut back unwanted fat and reveal a sleek & aesthetic figure underneath.

After reading other reviews online and inspecting it ourselves, we rounded up the overall conclusion on ShredCBD:

  • Promotes weekly weight loss with Green Tea Extract & Garcinia Cambogia
  • 40mg of CBD per capsule to boost fat browning [6]
  • CBD curbs appetite by affecting your brain’s endocannabinoid system [7]
  • Reduces daytime fatigue and improves sleep quality to help you wake up in the morning without feeling groggy
  • Improves mood & cognitive willpower making it easier to stick to your diet
  • Reduces stress hormones such as cortisol
  • Easy to take – 2 capsules per day before your meal
  • Free delivery in the USA

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 our experience inspecting ShredCBD and will continue to recommend it as an integral part of anyone’s supplementation routine.

What makes ShredCBD different from other fat burners is that it not only boosts weight loss, but it also enhances your mood, focus, sleep, recovery, and overall quality of life.

We were taken by surprise that such a seemingly simple CBD formula can provide so many benefits for women, with research around CBD supporting these results as well.

CBD is stimulant-free, which means you can take it at any time of the day to enhance your performance and weight loss, without risking side effects.

All in all, it’s a big thumbs up from us for ShredCBD.

  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.
