Getting ready for the beach? Here’s our top 3 fat burner list (updated for 2024)! If you already aren’t familiar with them, fat burners are dietary supplements that help you to shed unwanted weight by increasing your metabolism, elevating energy levels, curbing your appetite, and promoting mood & focus.
Our top fat burner supplements have all been analyzed thoroughly to ensure they’re free of any synthetic or iffy ingredients. We don’t trial these supplements ourselves, but we analyze their ingredients and compare them against the scientific literature to see if they work, are safe, and are properly dosed.
We base our list on:
- Completely natural results

When people think of fat burners, they assume it’s some sort of a magic pill. This is mostly the result of outrageous marketing campaigns from supplement companies. The reality is that there are no shortcuts to success in fitness.
However, by combining a regular exercise program and calorie-controlled diet with one of the weight loss supplements from this guide, you should see results faster. The natural ingredients in quality weight loss supplements work by helping you burn more calories and consuming less food. Over time, you should notice a significant improvement in your physique – and the fat burner may help you keep the results, too.
After reviewing over 30 fat burners in the past year alone, we’ve narrowed down our pick to the final 3 contenders, all coming from our manufacturer of choice – Roar Ambition. Thanks to their natural, safe, and highly effective formulas, the following fat burners can easily stand up to the big names on the market.

The Three of The Best Fat Burners in 2024
1. Instant Knockout CUT – Best Overall
Instant Knockout CUT is an expertly developed, fist-shaped fat burner that can help you cut weight relatively fast. Instant Knockout was originally formulated for MMA athletes. But due to its success, it later became available to the general public.
Instant Knockout boasts gleaming reviews and some of the highest ratings out of any weight loss supplement. Both men and women have been using Instant Knockout to cut back unwanted fat in an effective, safe, and natural way.
Effects that make Instant Knockout a potent thermogenic:
- Weight loss results can show after 5-6 weeks
- Curbs hunger cravings
- Protects lean muscle
- Maintains clean energy and focus throughout the day
Instant Knockout has been released in 2015 and remains among one of the most effective thermogenic fat burners. The reason for this is that Instant Knockout’s nutritionists and fitness experts constantly update the formula according to the latest evidence.
This is great – it tells us that we’re not getting a product that lives on its former glory, but one that is still arguably #1 after all these years.
Key Ingredients
The Instant Knockout formula was developed so that each ingredient works in synergy with each other, targeting weight loss from multiple angles. Here are a few ingredients that stood out to us:
- Vitamin D3 – multiple human studies show that vitamin D plays a key role in metabolic health, mood, energy levels, and hormone balance. Over 1 billion people worldwide may be deficient in vitamin D, which can result in weight gain, depression, and a host of other issues.[1]
- Cayenne Pepper – Cayenne pepper is full of capsaicin, a compound known to increase metabolic speed, leading to higher calorie burn. [2]
- Glucomannan -Glucomannan is one of the very best appetite suppressants around. This fiber expands in your stomach upon ingestion, making you feel full and satiated for longer. [3]
- Black Pepper Extract – Black Pepper Extract is a concentrated source of Piperine, a compound that enhances the digestion and efficacy of other ingredients in Instant Knockout CUT. [4]
The rest of the ingredients in Instant Knockout CUT work to improve not just weight loss, but also contribute to your overall wellness and cognitive well-being. This can be especially useful when you’re under calorie restriction and trying to maintain peak performance in the gym.

Our Thoughts on Instant Knockout
Instant Knockout CUT contains 120 capsules per bottle. According to the manufacturer, you’ll get the best results by taking 1 capsule, 4 times per day.
We understand why cutting weight with Instant Knockout felt surprisingly smooth and easy for many users. Its ingredients are shown to start working in the body almost right away.
The first change people notice is a reduction in the appetite, followed by a clean source of energy that lasts throughout the day; even if you’re low on calories.
After about 3 weeks is when you might start to see the first noticeable changes in your physique.
One annoying downside is that IKO is only available directly from its official website, and the price is in the premium range, but it’s sort of expected from a supplement of this level of quality.
After those initial 3 weeks, the results can slow down a bit, but this can be if you have slip-ups here and there. If you keep going for 2-3 months with this product, intense training, and calorie-controlled diet, you’ll see some pretty impressive differences in your physique compared with when you started.
The 4 capsules per day might also seem difficult to keep track of, but keep in mind that this will prolong the fat-burning effects of Instant Knockout, making it work 24/7 essentially.
Pros
- Natural ingredients
- Science-backed formula
- Real, lean physique results
- Trusted by pro boxers and trainers
- Excellent value
Cons
- 4 capsules per day, while highly effective, might be inconvenient for some people
- Only available at: instantknockout.com
Instant Knockout is Available at the Manufacturer’s Website
2. Hourglass Fit – The Best Fat Burner for Females
Coming in 2nd place overall is Hourglass Fit, a fat burner specifically designed for women who’re looking to achieve the hourglass figure. That is, a body with toned muscle and minimum body fat. However, when you look past the marketing, it’s clear that Hourglass Fit can work for both men and women. There are no gender-specific fat burners; there are only those with ingredients that work, and those that don’t!
With that being said, there are a few things about Hourglass Fit that make it stand out from other weight loss supplements. For one, it contains no stimulants. This makes it easy on your body and healthy for everyday use. If you don’t like the anxiety, jitters, and energy crashes that come as side effects of caffeine, you should look into Hourglass Fit.

Another key focus of Hourglass Fit is on ingredients that curb your appetite, which really makes a difference in terms of combating food cravings. Hourglass Fit works to keep you full throughout the day and night, making it easier for you to control your calories.
Benefits
- Targets stubborn fat including around the waist
- Promotes clean, long-lasting energy without the side effects
- Blocks sugar & salt cravings
- Contributes to the tightening of your legs and glutes as a part of the weight loss process
- Natural, lean physique results
So, what is inside Hourglass Fit capsules? Here’s a look:
Ingredients
- Vitamin B6 (1.7 mg)
- Vitamin B12 (2.4mcg)
- Chromium (as Picolinate) (125mcg)
- Zinc Citrate (8mg)
- Vitamin B2 (1.1 mg)
- Glucomannan (3,000 mg)
- Cayenne Pepper Extract (100 mg)
- Black Pepper Extract (5 mg)
- 5-HTP (150 mg)
B vitamins are added to give you a natural energy boost without the comedown, as tends to happen with caffeine.
Chromium contributes to healthy blood sugar levels, helping to prevent mood & energy swings throughout the day.
Meanwhile, Zinc, Cayenne Pepper, and Black Pepper Extract increase the levels of your fat-burning hormones so you’ll expend more calories during the day.
5-HTP is one of the ingredients in Hourglass Fit that helps to reduce your appetite. It elevates your brain’s natural serotonin levels; when serotonin is naturally high, we don’t feel hungry. What’s more, optimal serotonin levels are correlated with a bright & happy mood.
Hourglass Fit also contains a strong dose of 3,000mg of glucomannan. This fiber is going to expand in your stomach upon ingestion, giving you a long-lasting feeling of fullness & satiety.
What we appreciate the most about Hourglass Fit’s formula, is that there are no proprietary blends inside. You can see every ingredient and its dose on the label. This indicates transparency and confidence in the product. We know exactly what we are paying for.

How to take it
A 120-capsule bottle of Hourglass Fit will last you 30 days. For long-lasting fat-burning effects, you will want to take 1 capsule of Hourglass Fit, 4 times per day.
Similar to Instant Knockout, this way of taking a supplement might be annoying at first, but you quickly get into the routine. There is a good reason why the best fat burners have this serving frequency – it works.
Pros
- Helps you to burn unwanted fat and reveal toned muscle
- Substantial hunger control with glucomannan
- 120 capsules per bottle, caffeine-free and vegan-friendly
- Added nutrients for mood, focus, and energy

Conclusion
Hourglass Fit is a fat burner that offers excellent value for money, and we’ll say it once more, it works for both men and women! Just look at the ingredients in use and you’ll see it’s been formulated to the highest standard.
Whether your main issue is hunger control, lack of energy & willpower during the day, or perhaps burning fat in a specific area of your body such as the waist and legs, Hourglass Fit can help you achieve your fitness goals.
It’s also stim-free, which makes it ideal if you prefer supplements without pick-me-ups. Hourglass Fit is still going to give you plenty of energy thanks to its thermogenic ingredients that help with the conversion of body fat.
Overall, it’s a clean-quality product with an all-natural formula. There’s not much more to say about it, other than that it’s got a big thumbs up from us!

3. Burn by Hunter Evolve – The High-Dosed Fat Burner

Much like Instant Knockout and Hourglass Fit, Hunter Burn is made by the U.K. specialist supplement company Roar Ambition. What makes Hunter Burn different is it’s a highly focused fat burner that caters to a specific group of people – ambitious, high-achieving men who want a supplement that will help them feel good and look great.

Hunter Burn contains a generous amount of vitamin D3, matcha tea, and white kidney bean to enhance muscle-building, performance, and metabolic speed.

Matcha tea helps you to be burning calories at a faster rate.
Hunter Burn also contains konjac root which curbs appetite. Coupled with safe and potent 3,000IU of vitamin D to help you burn fat, build muscle, and support libido & performance.

Effects over 1 month:
- A good amount of daily energy without the crash
- More motivated to exercise, and increased performance in the gym
- Deeper quality sleep
- Improved concentration and deep work
