Best Fat Burner Supplements 2020 | Our Top 3 Picks

Top 3 Best Fat Burners on the Market

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. Chromium

Chromium is a trace mineral that is only found in very small amounts in our diet. Supplementation can help balance your blood sugar levels which is associated with reduced fat accumulation. In other words, while chromium doesn’t necessarily help you burn fat, it prevents you from gaining more.

Chromium insulin-regulating properties are also helpful for reducing sluggishness, food cravings, and mood swings after eating carb-heavy meals. To top that off, Chromium works to prevent snacking when you are feeling mentally ‘drained’.

Fighters Core has brought something unique and fresh to the fat burner market; it helps to protect your muscle tissue from catabolism when you’re on a calorie deficit.

#2 Instant Knockout – Best Fat Burner With Caffeine

Highest rated thermogenic for both men and women . 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 to the 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: https://www.instantknockout.com/

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 6-12 months by Roar Ambition as new research comes out.

Ingredients

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 Hourglass Fit – Best-Reviewed Women’s Fat Burner

Stim-free and packed with beneficial nutrients. It’s specifically designed for appetite reduction & mood support.

Taking 3rd place overall is Hourglass Fit, a well-rounded fat burner with a specialized ingredient profile. Although it’s mainly intended for women, it can also work for men. If you look past the marketing of the product, it’s clear that there’s no gender-specific fat burner. There are only fat burners with ingredients that work, and those that don’t.

However, there are some things about Hourglass Fit that make it stand out. It has no stimulants, which makes it easy on your body and healthy for daily use. If you don’t enjoy the jitters or other side effects of caffeine, you should look into Hourglass Fit.

Official Website: https://www.hourglassfit.com/

What’s more, Hourglass Fit has strong appetite suppressants to really make an impact on those nagging food cravings. Keeping you full throughout the day and night, and allowing you to see your diet through.

Ingredients

So, what’s exactly inside of Hourglass Fit? Here’s a closer look:

  • Vitamin B6 (1.7 mg)
  • Vitamin B12 (2.4mcg)
  • Chromium (as Picolinate) (125mcg)
  • Zinc Citrate (8mg)
  • Vitamin B2 (1.1 mg)

There are no proprietary blends in Hourglass Fit. You can see each ingredient and its respective dose on the label. To us, this shows transparency and confidence in the product. You know exactly what you’re paying for.

Our Thoughts on Hourglass Fit

Hourglass Fit has all the right ingredients in their optimal doses, that’s why it works so well. From glucomannan, to cayenne pepper and chromium for blood sugar regulation and appetite reduction.

We like that it has 5-HTP included too – this compound has been shown to boost mood & mental well-being. When you’re in a better headspace, you’ll be more inclined to make better decisions, which will then make you feel even more motivated to stick to your goals – leading to a virtuous cycle.

Another thing we like about Hourglass Fit is the price. Although it’s a top-of-the-line fat burner, it’s more affordable than some other fat burners, which makes it good if you’re on a budget. Being 100% vegan-friendly and free of fillers, the quality of Hourglass isn’t compromised either.

If you’re looking for a less-aggressive fat burner perfect for your daily lifestyle, Hourglass Fit could be the one!

Pros

  • Helps with the dieting needs of women
  • Improves results of a healthy diet
  • 100% natural
  • Side-effect-free formula
  • Great deals and offers
  • Cleanest quality

Cons

  • Doesn’t have a money-back program

#4 Hunter Burn – Best for Affluent Men

“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: https://www.hunterevolve.com/hunter-burn

Ingredients

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 with other fat burners, but surprisingly, we weren’t feeling jittery or lethargic later on.

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

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 Instant Knockout, 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
