Best Fat Burner Supplements 2020 | Our Top 3 Picks

best fat burner supplements

People who’re serious about getting in shape are serious about their lifestyle. A healthy diet and solid exercise program should be your starting point before considering a fat burner supplement.

However, we could all use an extra push from time to time. The name ‘fat burner’ is given to food supplements that are specifically formulated to help support your fitness goals.

Before we get to the best fat burners of this year, you should know that these supplements haven’t been proven to induce weight loss and fat burning. Rather, it’s the ingredients that they use – nutrients, antioxidants, plant extracts – that have clinical evidence backing their effectiveness for fat loss.

Each fat burner uses different ingredients, in different combinations, and in different doses. So each one will work for you a little differently. We’ve scoured the market for the best fat burners currently available – and after going through a lot of bogus and downright scam supplements, we’ve picked the 3 very best options on offer right now.

What are Fat Burners?

A fat burner is a popular type of food supplement, often made in pill form (and sometimes powder). A fat burner contains natural ingredients that help you to burn off body fat faster.

These ingredients, often sourced from herbs and plants, have various compounds which have been suggested in research to increase our body’s fat burning capacity.

Some fat burning ingredients target fat cells and help the body break them down. Other ingredients trigger thermogenic reactions within your body which puts your metabolism into high gear – burning more calories.

It’s important to choose a supplement that has ingredients that are supported by the latest scientific research. Many fat burners make big claims but use ingredients that have little to no benefits.

Needless to say, different products will have different formulas. So you’ll need to keep an eye on what’s going in your body, and what you’re paying for. Below we’ll list the best ingredients for fat burners and show you the dosages, so you can make an informed decision.

Why Take a Fat Burner Supplement?

Why should you consider taking a fat burner? The most obvious reason is that you want to burn off some unwanted pounds. Or maybe you’re just looking to feel more confident in yourself. Ingredients like green tea extract, cayenne pepper, and Garcinia Cambogia are common in the best natural fat burners and can take your progress to the next level when paired with a good diet and exercise routine.

Some of the benefits you’ll experience from taking a good fat burner include:

  • Faster metabolic rate
  • Improved ability of the body to use fat for fuel
  • Reduced appetite and food cravings
  • Increased mental energy levels

Let’s check some common ingredients in fat burners and how they might aid in reducing your waist size.

Best Fat Burning Ingredients

1. Green Tea Extract

Green tea is a great, tasty beverage that’s becoming a key ingredient in many supplements thanks to its powerful health benefits. It’s a popular addition to many fat burners as it’s been shown to have a number of actions that result in increased fat burning. (study1)

Green tea contains something called catechins. These are small molecules that trigger thermogenesis, a process where your core temperature rises, and so does the number of calories you burn with it.

Green tea can also help with the mental aspect of dieting. It boosts l-theanine levels which are linked to states of focus, calm and a sense of well-being – helping you to avoid food cravings.

2. Cayenne Pepper Extract

If you love spicy food, then you know cayenne peppers (aka, chili peppers). They’ve been grown and used for medicinal purposes for centuries. They don’t just add fire to your dishes, but also to your metabolism – resulting in increased calorie loss. (study2)

Chili pepper is also suggested to help you beat hunger by reducing the secretion of the hormone ghrelin, reducing your total calorie intake. (study3)

3. Caffeine

Ah, delicious coffee. The world’s most beloved hot drink is well known in the scientific community for helping with fat burning. Coffee does this mainly thanks to caffeine. High concentrations of the drug are found in each coffee bean, and it’s been shown in numerous studies to help with fat loss in two main ways:

  1. It sends signals to your fat cells which instructs them to get broken down
  2. Increases your resting metabolic rate

As caffeine is a stimulant, not every person will react well to it. In some cases, caffeine can lead to nausea, jitters, energy crashes and anxiety. This is most common in intolerant people. Luckily, some of the best fat burners which you’ll see below are stimulant-free.

4. Garcinia Cambogia

Garcinia is a common sight on the ingredient label of numerous fat burners and that’s because this tropical fruit has many fat burning effects. Clinical trials show that Garcinia helps raise serotonin levels in your brain, which leads to improved mood and satiety – preventing you from overeating.

Obviously, one of the biggest issues with weight gain is constant snacking or large meal portions. Feeling full for longer can help you avoid wanting to consume too many calories.

Garcinia also has compounds that are shown to have anti-obesity effects, and may help with fat burning directly.

5. CBD

CBD is an abbreviation for Cannabidiol. It’s a compound from the cannabis plant and has been shown to have a number of amazing health benefits – including increased fat burning. It’s non-psychoactive, 100% legal and has the opposite effects of THC.

New studies show that CBD reduces inflammation, boosts fat loss at a cellular level and is extremely effective at suppressing food cravings. CBD also works very well for reducing anxiety, which is helpful if you’re eating more when you’re stressed. This study showed that 79% of its participants experienced a decrease in anxiety from using CBD.

It’s non-stimulatory too, bringing the risk of side effects to virtually zero.

Here they are, our 1-2-3 in Fat Burning Champion’s League.

#1 ShredCBD – Best Rated Overall

2020’s highest rated fat burner, innovative stim-free formula, it can safely be stacked with most other supplements.

ShredCBD is making waves in the fat burner market and offers a fresh new approach to fat loss, while also being a supplement that can give a large number of other benefits to an individual’s life.

Online reviews and testimonials of ShredCBD have led to some exciting conclusions about this fat burner:

  • Helps you fight food cravings – ShredCBD reduces appetite and boosts your mental strength to avoid excess snacking.
  • Contains green tea extract – It’s one of the leading fat burning ingredients and is backed by science to boost metabolic rate, help break down fat cells and even boost cognitive function.

ShredCBD’s Official Website:


Each capsule of ShredCBD provides:

  • 20mg CBD Isolate
  • Green Tea Extract
  • Garcinia Cambogia

CBD is growing in demand due to its incredible wealth of beneficial properties. Each capsule of ShredCBD is filled to the max with 99% pure CBD derived from hemp. This compound has been shown in studies to impact inflammation, fat metabolism, appetite, and mitochondria (energy factories in our cells). All of this without causing jitters like caffeine or other stimulants.

ShredCBD is one of the safest fat burners on the market. It’s safely locked at way under the legal 0.2% THC limit, making it non-psychoactive and perfectly legal to take.

How it Worked for Us

Trying ShredCBD for 8 weeks without making any significant changes to our lifestyle. Everyone from our team kept training 3 times per week as usual [Editor: Well, except for Andy!] and we had a fairly restricted diet with an emphasis on lean protein and veggies, low amounts of carbs and some healthy fats. That said, we did slip up sometimes (as everyone does!), but we still achieved very surprising results, given the simplicity of this product.

We lost a solid amount of weight on average(as with any other fat burner), and were able to control our cravings much better. The improvement in sleep was most dramatical, and our stress levels went way down too. All of this kept us feeling great and shedding weight.

The biggest differences we’ve noticed:

  • Reduced appetite
  • Sustained fat loss
  • Not as fast-acting as aggressive stimulant-based fat burners, but it works really well if you give it time
  • Significantly better sleep and recovery after training
  • More focus and motivation in day to day life

Despite testing other fat burners, we have stuck with ShredCBD as an essential product in our daily routine as it stacks with other products easily and without issue and provides amazing results even when you’re not cutting.

The Good

  • Clinically backed formula with 40mg of pure CBD Isolate per daily serving (1200mg per bottle)
  • CBD alone can offer a lot more than many fat burning ingredients combined
  • Green Tea Extract and Garcinia Cambogia are drafted in for additional support
  • cGMP manufactured
  • Quick Free Shipping in America
  • Free 24-Page Fat Loss Guide (apparently it’s also sold separately for 10 bucks)

The Bad

  • Premium price due to high manufacturing costs of CBD isolate
  • Only available in the USA
  • Only sold direct at the official website

#1 Thermogenic and #2 Overall: Instant Knockout

Leading fat burner supplement with caffeine. It has highly effective ingredients in clinical doses.

Instant Knockout is a natural fat burner which can help you lose pounds in a safe and efficient manner. Produced by Roar Ambition, a specialist company from the U.K.

When it first launched, Instant Knockout was only available for professional MMA fighters to help them cut weight for fights. But due to how well this product worked, it was later released for general public.

It remains one of the top fat burners with excellent ratings from countless reviews online.

Differences we’ve experienced from using Instant Knockout:

  • Impressive levels of fat loss after 30-40 days
  • No uncomfortable hunger or food cravings
  • Significantly improved focus and energy levels through the day

Instant Knockout’s Official Website:

The makers of this supplement consult with athletes, nutritionists and experts to ensure they’re utilizing the best possible ingredients. Instant Knockout gets updated every six to twelve months by Roar Ambition as new research comes out.


Instant Knockout contains many of our recommended ingredients for fat loss. The best ingredients in IK are:

• 500mg of Green Tea Extract
• 100mg of Cayenne Pepper Extract
•1800mg of Glucomannan
•300mg of Caffeine Anhydrous 

Alongside these proven fat burners, Instant Knockout also utilizes some essential nutrients such as vitamins B6 and B12, along with Zinc and Chromium.

B vitamins are known for contributing to normal energy levels and the reduction of fatigue. Zinc encourages efficient carb metabolism. Chromium, on the other hand, helps prevent blood sugar levels from going too high and causing weight gain.

How it Worked for Us

Dropping pounds with Instant Knockout was surprisingly easy. We started to feel it working almost right away. The caffeine and cayenne pepper combo significantly reduced our appetite within 60 minutes of taking the capsules, while glucomannan provided us with more of a long-term appetite suppression.

We also had a clean increase in energy levels through the day despite being low on calories. After around 2-3 weeks is when we started to notice physical differences in the mirror – very, very surprising!

This is the fastest horse in the race in our experience.

Following the initial 2-4 weeks results continued, although at a slightly lower pace (we did slip up here a few times as well). But if you continue to take Instant Knockout continuously for 2-3 months you’ll be seeing some pretty significant differences in body fat compared to when you started.

One drawback is taking 4 capsules separately at different times of the day, which can be a bit hard to get used to. But this is the best way to ensure your body is constantly supplied with beneficial nutrients.

#3 Hunter Burn

“A high grade fat burner for driven men who want sustainable results”

Hunter Burn is a very targeted fat burner that contains a high dose of green tea, white kidney bean and vitamin D3. It’s a premium supplement for premium customers, but it doesn’t compromise in any department. If you’re looking for the absolute maximum, quality product, and are willing to pay, this is the one to consider.

Hunter Burn helps you:

  • Have more energy and focus throughout the day
  • Target stored fat with caffeine and green tea
  • Activate metabolic fat burning with Cayenne Pepper
  • Snack less thanks to Konjac Root (fiber which swells in your stomach, making you feel fuller)

Hunter Burn’s Official Website:


If you want the best doses of the market-leading ingredients, then this might be the fat burner for you. It’s nice to see that Hunter Burn uses a huge 3g of Glucomannan per daily serving, which will help you feel full and avoid snacking. This can be of particular benefit when you’re on a calorie-restricted diet.

Main ingredients in Hunter Burn include:

  • Matcha Green Tea (200mg per daily serving)
  • Cayenne Pepper (125 per daily serving)
  • L-Theanine (200mg per daily serving)
  • Glucomannan (3000mg per daily serving)

Vitamin D and White Kidney Bean Extract were added to Hunter Burn to augment its fat burning properties. Overall, it’s a well thought out formula.

How it Worked for Us

We got solid results from using Hunter Burn. The first effect was more obvious than ShredCBD, but surprisingly, we weren’t feeling jittery or lethargic later on.

We spent the last few days of our test using ShredCBD and Hunter Burn together – it wasn’t cheap, but let’s just say it was a hell of a fat-burning combo. (pun intended)

We took Hunter Burn with some resistance training, HIIT cardio, and a restricted diet with low amounts of refined carbs. We didn’t recover as fast as with ShredCBD, but the mental benefits were not too bad!

Main effect that we’ve noticed from using Hunter Burn:

  • More energy (similar to coffee)
  • Some decent fat loss
  • A slight energy crash in the late afternoon
  • Top quality ingredients meant we didn’t have any side effects
  • Reduced appetite

Hunter Burn is a top of the line fat burner, it’s just a shame it has such a hefty price. We understand that it’s formulated to provide maximum results, but some customers might prefer a cheaper fat burner. With that said, Hunter Burn is definitely an amazing value if price doesn’t bother you.

The Good:

  • Premium formula focused on quality
  • Innovative combination of ingredients
  • Science-backed
  • 90 Day Money Back Guarantee

The Bad:

  • Price is a bit high (it was made specifically for busy, affluent customers)
  • Only purchasable direct
  • Better suited for men

That brings our best fat burner supplements guide to the end.

Right now, we rate ShredCBD (for men and women) and Instant Knockout (for men and women) as our current top rated products on the market.

Both have their own unique advantages; whereas ShredCBD is completely stim free and promotes many more aspects of performance than just fat loss, Instant Knockout delivers a powerful punch with some of its natural ingredients. Combining them together is ideal, but obviously this isn’t cheap.

Hunter Burn is a great option for busy men who want the top quality. It enhances your mood in addition to directly ramping up your body’s fat burning potential.

We’ve looked into some of the things you should watch out for when buying a product, and pointed out a few of the best ingredients too.
