A distinctive clenched fist container makes this an awesome product on the outside, but what is on the inside? Well firstly, we should tell you that you don’t only need to take our word that this is a quality product. But this has been tried and tested by UFC fighters, such as Diego Sanchez, to cut down weight before their fights.

Check out the Instant Knockout Pro Athletes page to see which UFC and MMA fighters use and recommend this top fat burner. Obviously, this is a good fat burner for bodybuilding and cutting weight before a fight.

Their all natural ingredients make it a safe product to use and there is also the fact that the company’s reputation is sound. Partially because of their 90 day money back guarantee and the names that use their products.

What’s good about Instant Knockout?

The fat burning properties give you:

  • Quick and effective fat burning
  • More energy
  • A better focus when working out
  • Suppressed appetite

Problems using Instant Knockout?

Apart from the fact that it is one of the pricier products around there isn’t a lot you can fault with this fat burner. They say you get what you pay for, so this premium product is priced accordingly. When it is difficult to find anything bad to say, it is no wonder it is number 1 on our top 5 fat burners for 2020 list.

It’s been on the market longer than any of the other products on this list and with thousands of repeat customers and positive reviews, it’s really stood the test of time and continues to be the number 1 fat burner, trusted by professionals. 

How does Instant Knockout work?

For us there aren’t many top quality fat burners around. So many companies scrimp on doses and offer an inferior product.

As an overall product, the list of ingredients is where it gets its quality from. The fact that they managed to cram 10 effective ingredients into Instant Knockout means there are lots of great benefits.

Of the main ingredients that Instant Knockout has, the first two are metabolism boosters (green tea extract and Cayenne Pepper Seeds) and the third suppresses your appetite (Glucomannan). So not only will your body burn fat faster and more effectively, your calorie intake can be controlled by the lack of temptation to snack because you feel fuller for longer.

WebMD actually says that Cayenne Pepper is also good for appetite suppression. They advise that it has been found to curve appetite, especially in those who do not already eat spicy foods. have some good things to say about Green Tea Extract as they comment that they are anti-obesity and anti-diabetic which makes this ingredient even more impressive.

Because it is completely natural there were no side effects when we used Instant Knockout and we can’t find any information on anyone who has. The only thing we can find is hundreds of positive testimonials.

Straight in at number two is Hourglass. It is actually one of our top recommended female fat burners, and what a product it is!

What’s good about Hourglass?

It just does everything so well. It has all the ingredients you would want in a fat burner but tailored towards a female audience so it doesn’t rely on masses of stimulants. Hourglass is good because all the dosages are great and will get your body really burning fat and have you looking in the shape of your life.

  • Burns Fat
  • Contains Great Ingredients
  • No Side Effects
  • Money Back Guarantee

Problems Using Hourglass

We haven’t encountered any and as it is a completely safe product we don’t anticipate anyone finding an issue with this product.

They sometimes have sales and great discounts available, so whilst it’s still a premium product – it is often more cost effective than some of the others on this list.

Hourglass Works So Well

It has the likes of Vitamin B6 to turn calories into Glucose for you to use as energy. It also has Vitamin B12 which stops your body from storing fat – it is a great product.

There are appetite suppressants and really good ones at that. Glucomannan is known for being one of the most effective dietary fibers which swells in the stomach to make you feel fuller. Capsimax is also there to do the same. This will stop you from wanting to snack in between meals.

WebMD says that research has shown how people with lower levels of Vitamin D3 are more likely to be obese. Hourglass contains 1,000 IU of D3 which will be of great use.

Combine this with thermogenic ingredients like Green Tea Extract and it is clear that this is a fat burner that knows what it is doing.

With all natural ingredients and no proprietary blends, it is no wonder this product is becoming popular. It is also no surprise that it is ranked so high in our Top 5 Fat Burners for 2020 recommendations.

#3 Hunter Burn

Buy #3 Top Fat Burner Hunter burn from:

This is another top fat burner is from the mind of those people at Roar Ambition, so you know you are in good hands.

This is from their new premium Hunter range of products, and it lives up to the billing. The 6 ingredients are of the highest quality, making them incredibly effective.

To be honest – the formula is so good, it should earn #1 on this list, but because of the higher premium price we can’t quite award 1st place.

What’s good about Hunter Burn

  • Made by a reputable company
  • Contains key fat burning ingredients
  • Optimal dosages
  • Premium quality ingredients
  • Ship directly from the UK and USA
  • Money back guarantee
  • Natural ingredients
  • No side effects

It’s not just the fat burning ingredients that are so effective, it contains two of the best appetite suppressants as well. In Konjac Root and White Kidney Bean they have gone for two very reliable ingredients.

One study, in particular, found that Konjac Root contributed to weight loss and cholesterol reduction.

This is the same for everything else it does. Vitamin D3 ensures you will maintain muscle, and Cayenne Pepper and Matcha Green Tea are two great nutrients for burning fat.

L-theanine keeps you focused, making it one of the most impressively thought out formulas we have seen.  L-Theanine also promotes relaxation without drowsiness, making it synergistic with Caffeine ( It is this that helps it to take the edge off of any stimulants it is consumed with.

The ingredients are quality, the dosages are quality and so are the results.

What’s good about LeanBean?

  • Burns Fat
  • Gives you more energy
  • Improved sense of wellbeing
  • New improved vegan friendly formula

Problems using LeanBean – the Female Fat Burner?

Again, a top of the range product that is priced accordingly but if you want results it is worth the investment. We would have considered this as our number one fat burner had some of the dosages been a little higher. But it still contains a lot of what you want compared to the competition.

LeanBean Is Still Worth Your Time

Although LeanBean didn’t quite make our #1 ranked fat burner, it is only because Instant Knockout, Hourglass and Hunter Burn takes some beating, to be honest. However, we still consider it to be amongst the best female fat burners around. There are plenty of thermogenic nutrients contained in each serving meaning your body warms up and burns fat.

It is tailored towards a female market. LeanBean has many positive testimonials with lots of happy customers attributing their success to hard work and Leanbean.

It contains Chromium, an ingredient that WebMD say can decrease LDL (bad cholesterol) levels in those who have lower blood fat levels.

Also, it has Garcinia Cambogia. There is a study that showed how it helped in terms of fat loss in comparison to a placebo group after 16 weeks.

It is another safe product to use. Only natural, proven ingredients are chosen, and their effectiveness is there to be seen.

How Does a Top 5 Fat Burner Work in 2020?

Top 5 Fat Burners for 6 pack abs

The best fat burners on the market should do more than just burn fat. And all of the supplements on the list tick this box. There are many benefits a good product should offer…

Appetite suppressing

It’s not enough to encourage your body to burn fat, you also need some help with making sure you aren’t just instantly replacing all the hard work with more calories. The fiber content in a good supplement should mean you stay full and for longer.

Increased Energy

You will notice that many supplements contain caffeine and not just the best fat burners on the market. Any company producing a supplement will want it to give you the energy and do more with what they are offering.

You are able to burn more fat in the gym if your body has more energy to go the extra mile. If you are complimenting your workout with a lower calorie intake than you are used to, then the caffeine will be a welcome addition to keep your energy levels up.


Even when you aren’t exercising your body can burn more fat than usual.

This literally warms you up on the inside and the increase in metabolism means your body spends energy cooling down and burns fat to do so.

What To Look For In A Good Fat Burner?

Our advice is to look at the fat burner label and check out the ingredients. If there are natural options out there then why would you go anywhere else? Plus, watch out for the many fat burners that are made of proprietary blends of ingredients.

What’s a Proprietary Blend?

A proprietary blend (also called a matrix and other BS fancy names) is a blend of multiple ingredients listed under one item on the label. This means the manufacturer can get away with claiming they’re using the best ingredients… without disclosing exactly how much of each individual ingredient.

So you aren’t 100% sure you are getting a quality product. The ingredients could be very low, ineffective dosages where the company is saving money.

Unfortunately, a lot of the products we review have a total measurement of the ENTIRE proprietary blend of 10 ingredients, making up the amount you’d need for just one of the main ingredients to be effective – which is a dead giveaway that NONE of the ingredients are effectively dosed in that product and a clear signal that it’s a waste of money.

FORTUNATELY – None of our Top 5 Fat Burners use Proprietary Blends ✔️

All of the products on this list have honest approaches and disclose their ingredients and dosages openly. We’ve exhaustively reviewed them all to ensure they’re the best choice of ingredients and effectively dosed to get results, whilst also being safe and free from side effects and don’t contain any banned substances. We don’t recommend any products with a proprietary blend.

Do your research, read reviews (like this!) and see what people are saying about the company. Do they have a money back guarantee, do any celebrities and trusted athletes use their products?

Top Fat Burner Servings

Your intake is important. Any high dosage might help its effectiveness initially, but we don’t like risking crashing later on.

We prefer the method of taking smaller servings multiple times a day to make sure they are working for you all the time.

This will keep your metabolism constantly on the go – many of our top recommended fat burners spread the serving schedule out through the day like this for best results.

Top Fat Burner Ingredients

Along with the dosage amount, the actual ingredients themselves are vital to an effective fat burner.

Anything worth inclusion should be checked and researched. Too many supplements in this day and age are included because they sound good. Often though, only a few ingredients are proven to work, so make sure these are the ones in your chosen fat burner.

Read our in-depth review of proven safe fat burner supplement ingredients.

The Reputation of the Manufacturer

This is a big one, many fat burners spring up from nowhere with little information about who has manufactured it and in no time a lot of them disappear.

There’s nothing wrong with trying a new company if the risk of side effects is reduced by the natural ingredients. However, to make it on to our list of top 5 fat burners for 2020 we only consider manufacturers with a solid reputation and a good money back guarantee. Make sure you read the terms and conditions for any supplement money back guarantee before you purchase.

There are many testimonials for some of the bigger companies so do your research.

The Bottom Line

Unfortunately, even the best fat burners on the market aren’t an instant fix or magic bullet. Taking a fat burner supplement doesn’t mean you can just swallow a few capsules and let it do its work on its own. You need to put in the hard work in the gym and be disciplined with your diet to really see the best results and get the shredded physique you desire.

With all this in mind, one of these top 5 fat burners for 2020 can definitely help you lose that extra layer of fat and really show those abs quicker. They are much more effective than going it alone!

There’s so much hype and false promise in the world of fat burners. That’s why we’ve done the hard work of sorting the fakes from the real deals and given you our updated top 5 fat burners for 2020 that you can trust.
