Instant Knockout Fat Burner Review 2021

Review Summary:

Instant Knockout Fat Burner is relatively new but currently one of the popular  natural fat burning supplements sold in the market. It promises to burn fat like MMA professionals (company cites Diego Sanchez and John Dodson,two of the biggest MMA pro)

I have noticed some results (76Kg to 72Kg) in my body during my first few months of using the product. I found this product superior to other leading brands of fat burners for faster weight loss with  visible changes in just a span of three months. I highly recommend accompanying it with a balanced diet and regular exercise for better results. Note that it is not a magic fat burner pill. Fat burners should be used when you are stuck at a certain weight despite best diet.

Beware of fake products sold on Ebay or Amazon with a name similar to brand name and buy only from official website.

What is Instant Knockout Fat Burner?

This fat burner supplement was originally developed by Roar Ambition ( Testofuel, top ranked testosterone  is their product as well) for MMA fighters to lose weight before their match’s weigh-ins; but today, it is available to aid anyone who wants to burn their fats  while still retaining good muscle form.

Instant Knockout Fat Burner has lots of loyal customers with countless positive reviews. This product has become one of the most searched instant fat burner products online with repeat orders from many satisfied customers. Instant Knockout Fat Burner is a 100% legal and safe fat burner that is sold in the market today.

This supplement works as an effective instant fat burner that suppresses your appetite, boosts your metabolism, and serves as an energy booster.



Many people have suffered from obesity and struggle to lose weight. Unhealthy diet and poor lifestyle choices are the main reasons why people gain so much unwanted weight. While they seek the right supplement to help them lose weight, generally they end up buying the wrong product.

Instant Knockout Fat Burner does not only focus on weight loss. It also helps you keep your body’s metabolism high and prevents fat from being stored in the body. It also works as an appetite suppressant that keeps your food cravings at a minimum level. As a result, your cravings for unhealthy foods will be suppressed. This unique combination of both is hard to find in other fat burner pill products and explains why I like the product.

If you are an athlete that carries a bit of extra weight, this supplement is perfect for you. It will help you burn out those extra fats to have a leaner body suitable for fighting and maintaining your physique.

This product, as mentioned earlier, has undergone clinical studies & research and has been proven to help you boost your overall health aside from aiding you in weight loss.


What Ingredients are in Instant Knockout Fat Burner?

Instant Knockout Fat Burner claims to be made of one hundred percent natural ingredients. These ingredients are mixed together to help you achieve your desired results effectively along with a various number of benefits. They are as follows:

  • Green Tea Extract

Green tea extract is an essential ingredient that helps you see better results in your weight loss mission. This ingredient contains bioactive polyphenols called ‘catechins’ which attacks your body fat from different angles. It boosts your body’s metabolism and burns out stored fat in your body. It increases your internal heat by stimulating the release of norepinephrine in your body.

Also, a study shows that green tea extract does not only help you lose weight but also keep you from gaining weight.

  • Caffeine anhydrous

This ingredient fires up a hormone in your body to convert more energy by burning more calories to help you eat less and have lots of energy to use for the day. Caffeine is also a natural stimulant that enhances your energy levels and stamina and helps you stay alert and focused.

  • Glucomannan

This ingredient’s main function is to reduce your food cravings by giving you a feeling of fullness. This ingredient is a complex source of carbohydrate that has a beta-D-Mannose and beta-D-glucose long chain reaction. This means that this ingredient can pass through the stomach without being digested, thus giving you a feeling of fullness for a longer period of time.

This nutrient is a great ingredient because it does not only reduce your appetite but also improve your metabolic health.

  • Vitamin B6

This is the one that pulls all the ingredients of the supplement together. It improves how your body synthesizes your energy to help you support a healthy lifestyle. It also helps in fat burning by accelerating your metabolism.

Vitamin B6 aids your body in absorbing amino acids to help you build muscle. Moreover, it also regulates fats and carbs, thereby helping you control your diet with ease.

  • Vitamin B12

This ingredient also helps convert your food into useful energy. This helps you last longer during exercise and increase your body’s metabolism. This vitamin also improves your immune system.

Vitamin B12 helps in breaking down fatty acids, maximizes protein synthesis, and improves carbohydrate digestion. Mix it all together, and you’ve got a perfect recipe for a more athletic and leaner body with better physical performance.

  • Cayenne Pepper

This spice is contained in most diet pill supplements in the hopes that it will raise body metabolism. A higher and faster body metabolism means the better ability of your body to burn calories. A study also shows that this ingredient increases fat burning especially when paired with regular exercise.

  • Zinc

This ingredient is one of the most popular and important nutrients when talking about a leaner health composition. It boosts the hormone called ‘testosterone’ which is responsible for increasing protein synthesis.

This nutrient also helps your body in converting fats, protein, and carbohydrates into energy. Having enough energy to fuel your body is important especially when you are exercising to get in shape.

  • GTF Chromium

GTF Chromium regulates your cravings for sugar and carbs which contributes to unwanted weight gains. This mineral is commonly found in meat, whole grains, and vegetables. Due to its properties, the sugar and carbs that you take are converted into energy.

  • Piperine

This is an extract from black pepper with a bioactive chemical formula that aids in weight loss, digestion, and thermogenesis (the body’s process of heat production). This also suppresses the storage of fats in the body.


  • Green Coffee Bean

For those people who haven’t heard of green coffee beans before, they are simply unroasted coffee beans. They don’t have a caffeine content but have a compound known as chlorogenic acid. Chlorogenic acid is a substance that slows down the fat absorption rate from food.

This ingredient reduces your sugar cravings and also lowers your body’s cholesterol level, thereby boosting your health and body composition.

Can Instant Knockout Fat Burner really help you lose weight?

It’s been only three months since I started using Instant Knockout Fat Burner and I can notice slight visible changes in my weight.
