Best Fat Burner Supplements in 2019


Our definitive guide to the best fat burners on the market will help you pick a quality option.

Losing weight is no easy task, and while a healthy calorie-restricted diet and exercise is the key to success, sometimes you may need a little extra support. In which case, you may be considering a fat burner supplement.

A ‘fat burner’ is a product designed to assist with weight loss. Manufacturers create these supplements to get you ripped by using natural ingredients like plant extracts and vitamins that have been linked to losing weight in some way.

These supplements may be popular in general, but they don’t have the best reputation. Often, they’re sold as miracle cures to help you drop weight, when in fact they are not proven or even likely to do so.

With that in mind, we need to clarify that so-called ‘fat burners’ aren’t going to make you lose weight alone. While we can explore the effects of the ingredients within the supplements individually, we can’t guarantee they’ll work within the context of the formula.

They’re also designed to be an aid to a calorie-restricted diet and exercise; therefore, they cannot be relied upon solely for weight loss. They may be able to support your efforts, but there are no guarantees and, as we all know, exercise and a good diet is the real key to weight loss.

Having said that, these are increasingly popular supplements, many consumers claim they help them with their efforts and they could act as a crutch when things get hard.

Let’s take a look at the best fat burners in 2019 to help you find a safe and effective product.

Instant Knockout

Most popular fat burner

Taking the win for most popular fat burner is Instant Knockout.

Originally designed for MMA fighters, this product made its way to the mainstream and has been a firm favorite of many gym-goers since.

We wanted to know what makes Instant Knockout such a big hit with those who buy it, so we put it under the microscope in a Sports Daily review.

After examining the formula, we found it to be of a very high quality. It’s packed with some of the most popular ingredients in this industry which are all backed by scientific research, and served to generous levels.

All of this adds up to warrant this product as our top pick for most popular fat burner.

Instant Knockout ingredients

This supplement consists of 10 natural ingredients, that have each been added with the intention of improving your ability to lose weight.

To understand how it might help you with your fat loss efforts, we’ll take a closer look at some of the key players.

Green tea extract

This is a widely used and recognized thermogenic. That means it can have an impact on your metabolism. We found a review of 11 independent trials which all identify its thermogenic properties.

Cayenne pepper seeds

Capsaicin within cayenne pepper seeds has also been shown to trigger a thermogenic reaction within your body. This should also help to increase calorie burn.


This is a soluble fiber taken from the root of the Konjac plant. When in the stomach, it expands into a gel-like consistency. This makes you feel fuller, which should suppress appetite, reduce food intake and reduce cravings.

Caffeine Anhydrous

This provides energy both mentally and physically. It is also a potent thermogenic that can promote fat oxidization. It can be over-used and therefore potentially dangerous, but this supplement offers reasonable servings.

Vitamin B6 and B12

These are key vitamins your body needs to perform a huge range of metabolic processes. In studies, B vitamins were shown to increase fat oxidization.

How to take Instant Knockout

The manufacturers have created Instant Knockout to be taken over four, one capsule portions throughout the day.

Timing can be very important with a supplement that contains appetite suppressants and stimulants.

The appetite suppressant can help you to reduce your food intake in meals, therefore you may want to take it before you eat.

Caffeine can also cause insomnia if taken too close to sleep, therefore we recommend taking your last capsule no later than 5 hours before you usually go to bed.

As such, we recommend you follow this pattern:

First capsule immediately after waking, before breakfast Second capsule 30 minutes before lunch Third capsule in the mid-afternoon Fourth capsule 30 minutes before your evening meal

All the research surrounding the ingredients within this supplement display results when they’re taken consistently over a prolonged period of time. As such we suggest you continue to take Instant Knockout in this way too to improve your chances of results.

Instant Knockout price

One bottle of Instant Knockout provides 120 capsules, which should be enough to last 30 days.

One bottle: $59/£35

Two bottles + free US/UK delivery: $118/£70

Three bottles + one free bottle + free worldwide delivery: $185/£110


Instant Knockout testimonials

One of the best ways to find out what you can expect from a fat burner supplement is to look at how well it performs for other consumers.

As the most popular fat burner on our list, of course it came with a lot of some very positive reviews that say the product has helped them to lose substantial amounts of weight.

Instant Knockout is also recommended by athletes like John Dodson, Diego Sanchez and Holly Holm.

While we’re aware these are likely to be paid endorsements, we still find it reassuring that these athletes are willing to put their name to it.

Of course, there are a number of reviews from customers saying Instant Knockout didn’t help them to lose weight. We take these into account, however, we’re overwhelmed by how much positive feedback this supplement got. That’s why it’s our top pick for most popular fat burner after all.

Hunter Burn

Highest quality


This is a new type of premium supplement that takes a very different approach to fat burners.

Where so many manufacturers opt to over-fill their products with caffeine, and add a few well-known ingredients to the supplement facts at very small servings, Hunter Burn does quite the opposite.

This stimulant free fat burner uses high-quality ingredients at some of the highest servings we’ve seen.

It’s this approach that has earned Hunter Burn our top spot as highest quality fat burner supplement.

Read on to find out why.

Hunter Burn ingredients

Konjac root extract


This is a soluble fiber that expands and thickens slightly when it hits your stomach. This should help you to feel fuller, which suppresses the appetite and could even reduce portion sizes. This is served at 3,000mg which is the most we’ve seen in a fat burner supplement.

Vitamin D3


This this is usually used in testosterone boosters; however, it’s also been linked to fat loss, which is why it’s in this formula. Hunter Burn provides 750% of your recommended intake.

Matcha green tea


Green tea is widely used as a thermogenic in fat burners due to its potent catechins. Matcha has been shown to provide almost three times the amount of catechins as normal green tea, making it a potentially more effective option.



This is more of a nootropic than a fat burner, as it creates a sense of calm focus. However, recent research suggests it may also help to improve your ability to resist cravings.

White Kidney Bean Extract


This is natures only known carb blocker. It can help to reduce the amount of carbohydrates your body absorbs when digested.

Cayenne pepper


This ingredient is a potent and popular thermogenic supplement, which is backed by an array of studies and research. This should help to boost your metabolism and fat oxidization.

How to take Hunter Burn

This supplement is served over six capsules a day, which is what allows it to provide such generous serving sizes.

As Hunter Burn contains appetite suppressants, it’s important you take the supplement before you are due to eat. This should help you to reduce your food intake and stay in control of food cravings.

To ensure you’re getting the most out of them, we recommend you follow this pattern:


Two capsules, 1 hour to 30 minutes before breakfast Two capsules, 1 hour to 30 minutes before lunch Two capsules, 1 hour to 30 minutes before dinner

Hunter Burn price:

One bottle: $75/£55


Two bottles and free US/UK delivery: $150/£110


Three bottles + one free bottle + free worldwide delivery: $225/£165

If you do decide to opt for Hunter Burn, the three-bottle bundle may be the best option to save you money. We find this a particularly good offer, as weight loss happens over a prolonged period of time, so opting for more bottles, at a lower price should help you throughout.

Hunter Burn testimonials
