Best Fat Burners 2020 – Our Updated Guide

Best Fat Burners 2019

Our handy guide aims to show you some of the leading fat burning supplements available on the market today.

Fat Burner Overview

Trying to get into shape and lose some of the more stubborn areas of fat requires a lot of hard work, patience and more importantly dedication. The best place to start to reach your goals is a good diet and taking regular exercise, way before thinking about reaching for a fat burner.

There are two basic type of so-called fat burners, one that helps you to fell less hungry and therefore eat less, making your body burn fat and not store it. The other basically makes you go to the toilet more and gives you not just runny, but greasy waste products.

Don’t be fooled by some claims that these are somehow magic solutions to burn away the fat without having to work for it, they just don’t exist. There really is no shortcut to weight or fat loss success, you need to work at it and keep going, especially when that going gets really, really tough.

Green Tea Fat Burner
Green Tea is a commonly used Fat Burning ingredient

So which to take, well I know which ones I prefer and they are all listed below. They have the ingredients that will help to feel full and naturally help your body to burn fat. These products are the best around because they all contain glucomannan, which is one of the only ingredients that is approved by the FDA and FSA for it’s fat burning properties.

However, it is important to realise that although they contain ingredients that can help, most of the supplements that call themselves fat burners, including all of the ones that I have reviewed on this page, do not come with any proof that they can or will help with fat loss and fat burning. They are all supplements that have been formulated and designed to support your fat loss goals and they usually contain a number of natural ingredients including plant extracts along with vitamins and minerals, most of which can be bought separately in a chemist or supermarket.

The difference with these supplements is the stacks have been formulated to work together in the right proportions, so you don’t need to worry whether the ingredients you are taking together are safe. One note of caution, make sure the supplement you are taking has the ingredients clearly stated, some propriety blends won’t have the full ingredients so you won’t know what you are taking.

No matter which fat burner you choose, make sure it has glucomannan and in a decent quantity. There is evidence [1] to suggest that a dose of around 2-4g per day will aid weight loss. Therefore, you want to look for a supplement that gives you at least this amount per serving. On this basis Hunter Burn has the most glucomannan, which although is a great sign, isn’t the whole picture.

Also worth looking out for is the amount of caffeine in the product, which can lead to unwanted side effects and not a lot else. With most of the supplements here there is an amount of natural tea extract, be that Matcha or just green tea, both of which already have caffeine, so you want to watch which products also have an extra kick just to make it feel stronger.

Set Your Fat Burning Goals

Your main goal should be to eat less calories then you burn, not by starving yourself (although there are proven benefits to intermittent fasting over short periods where you eat up to 600 calories per day). The best way to achieve this is to eat less and more healthy food and take regular exercise.

Taking a fat burning supplement can’t be a substitute for a healthy balanced lifestyle. They can help you tone or burn excess fat, but you are going to have to put in some effort and work hard to really have any lasting effect.

Whatever your fat burning goals are for 2020, however you decide to achieve them, be it with diet and exercise or the use of a fat burner, we hope you find the following guide to the best fat burning supplements useful.

The Top Fat Burners of 2020

Here is our look at a range of the best fat burners of 2020, all available to buy online today, they are:

#1 Hunter Burn – Best All-round Fat Burner

Product website:

Hunter Burn is the best fat burner on the market right now, read on to find out why.

Hunter Burn Premium Fat Burner

Made with premium ingredients, Hunter Burn has all of the elements we would expect in a fat burner with one major exception, there is no added caffeine. This is great if you don’t want any stimulants or are sensitive to caffeine, I know my partner won’t have anything with caffeine in, so this is great for them.

Caffeine is still a great help in loosing weight as it can help to boost your metabolism and give an energy boost, but it can also make you feel jittery or nauseous. But enough about that because Hunter Burn doesn’t contain caffeine, so you won’t get any of these side effects.

Main Ingredients

Now we know what isn’t in there what can you expect so see in Hunter Burn?

  • Vitamin D3 – Can help to reduce calorie consumption and can help to reduce new fat cells being formed in the body.
  • Glucomannan – This water-soluble dietary fibre root works to reduce the absorption of protein and fat in the body, whilst also taking up space in the stomach making you feel fuller for longer
  • Cayenne Pepper – A thermogenic that can help to speed up your metabolism, burn more calories and decrease your appetite
  • Matcha Green Tea – an antioxidant known to help to burn fat more quickly during exercise
  • White Kidney Bean – Helps to stop starch turning into sugar in the body and helping to promote fat loss
  • L-Theanine – Can stimulate your metabolism and help to burn fat in the body. It can also help to increase your mood and increase energy levels. Also found in Hunter Focus for its mood enhancing properties

Here is the full ingredients list as shown on the Hunter Burn bottle:

Price and Where to buy

As you would probably expect with a premium product there is a premium price tag. Hunter Burn is only available on the Hunter Life / Roar Ambition Website (at the time of writing these are one in the same thing).

There are three options, a single bottle, two bottles which currently has a deal on for free UK and USA delivery and an Ultimate Fat Burning System of four bottles (3 + 1 free) and free delivery in the USA and UK.

Prices start at $75 / £55 / €60 / AU$100 for a single bottle so buying the Ultimate System of 3 + 1 free works out as a saving of 25% plus free delivery.

This product is only available directly from the manufacturer and isn’t available in shops or on Amazon.

The product is manufactured in the USA and UK in facilities that are approved by the cGMP and FDA.

When you buy the Ultimate Fat Burning System, you are covered by a 90-day guarantee, this is one of the main reasons why the products are only sold direct is so they can offer a 90-day money back guarantee.

There are different currency and shipping options to allow the products to be shipped worldwide and have fast and tracked shipping options from both the US and UK, where the distribution depots are located.

How to Take Hunter Burn

One of the frustrating things about this product is that the instructions state you should take 2 capsules 3 times per day, so take 6 capsules per day. That’s a lot of times to remember to take a fat burner.

When I was taking Hunter Burn, I started off with just one capsule at a time as you can feel a bit full if you take two to start with as the Glucomannan does its thing. Take with plenty of and at least 30 minutes before you eat to make sure the other ingredients take effect and keep your appetite down.

Testimonials and Reviews

This is a new product for 2019 so there are no published reviews for Hunter burn at the time of writing. I have taken this product myself and can say that it does have fat burning properties, appetite was suppressed, and I did loose both weight and body fat whilst taking Hunter Burn.

I will update this post once there are reviews from customers posted on their website, something that Roar Ambition are always keen to do.

Final Thoughts

If you are looking for the best Fat Burning supplement of 2020 and are not put off by the Premium price, it’s one of the more expensive supplements in this category, then Hunter Burn is the one for you.

It has many of the best ingredients including Matcha Green Tea, Cayenne Pepper and Glucomannan, without having any additional caffeine. One of the drawbacks of this product is that the capsules are not suitable for Vegetarians or Vegans as they contain gelatine.
The number of capsules you have to take per day is a bit of a bind but if you are serious about your fat burning goals it is something that you just have to live with.
Bottom line – I love this product and now we have Christmas out of the way will be using it as part of my fat burning and weight loss objectives for 2020.

#2 Instant Knockout – Best Fat Burner with Workouts

Product website:

Instant Knockout is one of the most popular fat burners on the market today, it would have been our number one product it not been for the new Hunter product range.

Marketed as the product of choice for MMA fighters and boxers, Instant Knockout is packed with the usual high-quality ingredients you would expect from the manufacturer, Roar Ambition. The quirky bottle reminds me of the fist used for Diesel Only the Brave aftershave!

Main Ingredients

Instant Knockout contains many of the same ingredients as Hunter Burn, in different quantities and there are a couple of differences which we will highlight here.

Along with these ingredients that Instant Knockout shares with Hunter Burn:

  • Glucomannan
  • Cayenne Pepper
  • Vitamin D3
  • Green Tea Extract – although similar this is not the Matcha Green tea found in Burn

The following ingredients are only in Instant Knockout for their own fat burning properties and to give an extra punch to get you through your workouts!

  • Caffeine anhydrous – basically caffeine with a kick to stimulate your nervous system and help to intensify your workout, boosting fat loss by elevating fat oxidation
  • Vitamins B6 and B12 – These two essential vitamins can help with the reduction of tiredness and fatigue whilst heling to break down fatty acids
  • Chromium – Helps with the maintenance of normal blood glucose concentrations, reduces appetite and food cravings
  • Zinc – Elevates protein synthesis (building protein in the body), helps to process carbs, fat and protein into fuel for the body, especially useful when training hard

Here is the full ingredients list as shown on the Instant Knocout packaging:

Prices and Where to Buy Instant Knockout

Instant Knockout is only available online from either the Instant Knockout website or from the manufacturer Roar Ambition. The advantage of buying from the manufacturer is you can buy one Instant Knockout along with any other product to get free worldwide delivery, otherwise buying one from anywhere else will add delivery.

Each bottle has 120 capsules which is enough for 30 days, or as Instant Knockout suggest, one month (so only months with 30 days then)

There are three options, one month, two months and an Ultimate Shredding Stack of four bottles (3 + 1 free) and free delivery worldwide.

Prices start at $59 / £35 / €40 / AU$75 for a single bottle so buying the Ultimate Stack of 3 + 1 free works out as a saving of 25% plus free delivery.

Instant Knockout Bottles

Like all Roar Ambition products, Instant Knockout is manufactured in the USA and UK in facilities that are approved by the cGMP and FDA.

When you buy the Ultimate Shredding Stack, you are covered by a 90-day guarantee, this is one of the main reasons why the products are only sold direct is so they can offer a 90-day money back guarantee. This is available on the Roar Ambition website and Instant Knockout.

There are different currency and shipping options to allow the products to be shipped worldwide and have fast and tracked shipping options from both the US and UK, where the distribution depots are located.

How to Take Instant Knockout

Like some of the other Fat Burners we have tried the routine of taking Instant Knockout is a little strenuous in that you have to take one capsule four times a day. More times than Hunter Burn that I found hard enough to follow.

Take the pills in between meals for the best results and I wouldn’t take these late in the evening because of the amount of caffeine in them.

Testimonials and Reviews

There are loads of testimonials and reviews of Instant Knockout across their own website, YouTube and other social platforms. We would expect that because this product has been around for a few years it is well used and well liked.

Instant Knockout has some great reviews and endorsements from the MMA and boxing world, showing that this product is good for people who are active and want to lose fat but are already in shape.

As always there are plenty of people who Instant Knockout doesn’t work for and they can be quite vocal on social media and other platforms. It is impossible to tell if this product just didn’t work, or if they didn’t use it as part of a workout plan. As previously stated we think with this blend of ingredients Instant Knockout will work best as part of a workout and healthy eating plan.

Final Thoughts

Instant Knockout is the fat burner to take with a workout to get your metabolism going, increase your workout intensity and build protein in the body. Put all of this together and you have a fat burner that really is for those who could be MMA fighter or boxers, not that you have to be, you just need to be a bit fitter and train to get the most out of this product.

I on the other hand am not that good at training or working out for that matter, which is why I prefer Hunter Burn, but that is personal preference. Instant Knockout is, and will continue to be one of the top fat burning products on the market that is suitable for both men and women alike.

#3 Lean Bean – Best Fat Burner for Women

Product website:

Lean Bean Single Product
We have a more comprehensive review of Lean Bean from one of our female product testers, because Lean Bean is aimed directly at women rather than being for both men and women. You can read that review here. We have extracted the best bits of that review on this page as part of our review of the best fat burners on the market.

Being specifically for women caught our attention because there are few products that market themselves in this way, the only other we know of is Hour Glass which is reviewed below.

Lean Bean has a blend of 12 ingredients, most of which you can find in the other products reviewed on this page. What makes it slightly different is the levels of each ingredient you will find in this product. We will take a look at these ingredients a little later in this review.

One thing to note is that the capsules are suitable for both vegetarians and vegans, this seems to be a growing trend within the supplements market but not all of the leading products are following suit, so for now this is one of the only fat burners we have reviewed that are truly suitable for everyone including vegans.

Main Ingredients

We have already discussed most of the ingredients that are in Lean Bean on our other Fat Burner overviews above, that’s probably because Lean Bean uses most of the more common ingredients found in fat burning supplements.

There are 12 ingredients in the Lean Bean Formula, these are:

  • Glucomannan
  • Cayenne Pepper
  • Vitamin B6, B 12
  • Chromium Picolinate
  • Green Coffee
  • Green Tea Extract
  • Turmeric
  • Garcinia Cambogia
  • Acai Berry
  • Piperine
  • Raspberry Ketones

Like Instant Knockout and Hunter Burn, Lean Bean contains some of the most powerful fat burners on the market – Glucomannan, Green Tea Extract and Cayenne Pepper.

Where Hunter Burn doesn’t have added caffeine, Lean Bean in laced with Green Coffee in the same way as others within the fat burner category.

What we haven’t seen before is the use of Garcinia Cambogia, Raspberry Ketones and Acai Berry

Prices and Where to Buy

Like most premium products, and this is a premium product, you can only buy Lean Bean from their website.

There are three buying options of one month, two months and the inventively named Bikini Body Bundle, which is three plus one free.
As an add on you can also purchase a Lean Bean branded sports bra, just to re-affirm that you need to lead a healthy lifestyle whilst taking any kind of Fat Burning product. There is also a free e-book with the bundle, but as we only tried the one-month supply haven’t had sight of this.

Prices start at $59/ £39 / €35 / AU$75 and as usual with this type of website you get a discount for buying the Bikini Body bundle and free delivery when you buy more than just the single product.

Testimonials and Reviews

Plenty of positive and negative reviews with Lean Bean as there are with most other supplements, this product either works for you or it doesn’t.

Well marketed for women it seems to be popular on social media platforms, with lots of before and after transformations. Best to remember that a lot of what a Fat Burner does and how it works depends on how well you eat and the level of activity you do alongside it.

Regular training and a healthy diet are pretty much pre-requisites to losing fat not just losing weight.

Final Thoughts

What we haven’t found is anything that is truly aimed directly at women rather than men and it would be interesting to see if men get the same results using this fat burner as women.

It might just be clever marketing to produce a fat burner just for women, but we think this would be just as good for men and likewise women would be just as well taking Hunter Burn or Instant Knockout depending on your goals.
