Instant Knockout Fat Burner Review [Side Effects And Benefits]

To judge a person by their physique and appearance is something that comes easy to all. However, no matter how wrong that might sound, and indeed it is so, the first impression is generally made at a glance.

So, if we think about it, body-positivity comes with an enormous amount of courage and acceptance for people, especially on the heavier side who have to deal with the obnoxious mindset of a body-shaming society.

And although there have been a million hacks advertised for fast and effective weight loss, a product that delivers exactly what it promises is hard to come by.

And this is precisely where the question of the alleged wonders of the “miracle” supplements come in.

One such highly raved supplement for burning off the flab is Instant Knockout that was launched not too long ago. Although this one’s being hailed as a wonderful quick fat burner, one can never be too sure if they don’t use it for themselves or even have a first -hand review of it.

You are very welcome to our review of the Instant Knockout. So, let’s get started, shall we?

About Instant Knockout

Instant Knockout is what would you generically call a “fat burner” that helps you shed unnecessary fat and in turn, gain in muscle mass when coupled with a proper workout regime. It is manufactured by Roar Ambition.

The nutritional supplement or booster brings you the best achieved by a combination of a fat burner with an appetite suppressant that is formulated using a potent blend of natural ingredients.

Instant Knockout is fundamentally designed by professionals in the field of combat sports and significantly endorsed by professional boxers and MMA (Mixed Martial Arts) fighters, who need to maintain a rigid set of body-weight as a criterion to remain in the field.

Because of that, Instant Knockout as weight cutting supplement has become a popular go-to for all fighters in this field.

The unique and powerful concoction helps you burn away excess fat and attain a chiseled, ripped body when paired up with the ideal lifestyle. The supplement also ensures that you are well able to preserve what you have gained in muscle mass. You don’t have to worry about losing energy or stamina as the formula take ample care of that by regulating your appetite and the total fat content of your body in the right way and hence, keeps tabs on the proper functioning of your metabolism.

Also, one of the most interesting things about the supplement is that the bottle containing the supplement capsules is shaped like a fighting fist which justifies the fact that it is indeed meant for fighters!

Why we chose it?

As life would have it, most of us weren’t of those kids who were born pretty healthy, to be honest. Many of us we’re underweight for as long as we can remember, with a host of health complications that were a companion to us from the start.

Now, even though we weren’t all that surprised when one of us was, named Joey diagnosed with hypothyroidism at 14, he felt its full effect on his health by the time he turned 25.

And although Joey had taken to working out by that time, he realized that nothing he did brought him any solid results or even close to what we had expected they would. He wasn’t really gaining anything in muscle-mass but kept putting on weight in excessive fat that gradually pushed him towards being prematurely obese. Also, there was the problem of not being able to work out for long or even daily as he lost a lot of stamina even while doing the simplest of things.

As a result, Joey’s trips to the doctor’s increased while his health suffered immeasurably. He wasn’t able to concentrate on my term papers.

But, the last nail on it, however, was when he realized that he had lost his sex-drive and wasn’t really able to get a hard-on for that matter. If all weren’t enough already, this was that very thing which broke his emotional health and shattered his confidence.

Joey’s experience with Instant Knockout

“It was indeed around the worst moments of my life that I finally found a glimmer of hope when I stumbled on Instant Knockout on one of the gymming websites I followed back then. Although I had substantial doubts regarding what seemed to be a gimmicky product, I was desperate to try anything out at that point of time in my life as long as that didn’t involve steroids or drugs of any sort”, says Joey.

Thankfully, the supplement did have a significant portion of positive reviews which actually included certain nutritionists, gym trainers as well as people who had been previously underweight and considerably benefitted by the supplement thereafter.

We decided to let Joey take a chance and ordered his first bottle of the pill. However, we did consult our doctor before going on the product, and although he couldn’t confirm a hundred percent on its efficacy, he did signal us green on the list natural ingredients which made the product safe for Joey to consume.

Joey took Instant Knockout for about four months before he decided to infer the results from it.

Well, at the end of this time period, we realized that the formula had clearly worked out for Joey. It gave him just over a kilogram in overall body-weight.

He also felt a lot more active and fortunately, spirited and energetic enough to gradually increase his workout regime. And while Joey stuck to a strict and well-balanced diet with regular workouts, these little achievements boosted his confidence which in turn, made a huge difference in his approach and outlook towards the efficiency of the product. And as he felt more and more confident about his body, the more he felt hopeful towards a healthy future, making efforts with renewed vigor!

How does the product claim to work?

Instant Knockout works mainly by setting three particularly targets and achieving them methodically once it’s introduced into the system.

  1. By boosting metabolism: It increases the body’s Resting Metabolic Rate (RMR) and the Active Metabolic Rate (AMR) [to calculate yours click here], that burns off more calories over the course of a single day. Moreover, It prevents the body from absorbing fats at a cellular level that makes a significant difference in the regulation of lipids in the system.
  2. By reducing cravings: The supplement is formulated with potent, natural appetite suppressants which cut down on cravings and regulates appetite in the correct way, helping the body intake as much as it requires without piling on unhealthy junk food. This way, it prevents the body from taking in unnecessary calories, hence facilitating the fat burning process.
  3. By boosting energy levels: The process of losing weight and sticking to a proper diet and workout becomes increasingly difficult when the body begins to lose energy and stamina. However, the supplement comes with powerful energy boosters that keeps you spirited, focused, and motivated on your journey to a fit body!


Instant Knockout is strategically formulated with a potent blend of active natural ingredients that are bound to help your body get into a system where it can safely lose excess fat and gain more in muscle-mass without losing stamina.

The following is a list of all the ingredients that are contained in the supplement for you to know all about:

  1. Green Tea Extracts (500 mg)

Green Tea is beneficial in more ways than what we take it to be. It increases the metabolic rate that enables your body to use up the excessive amount of stored fat in your body to burn even more fat, by initiating the process of thermogenesis. In the thermogenic state, the core temperature of your body is raised for burning off excess fat. Green Tea extracts also build up the endurance of the body, helping you to work out for longer durations of time.

  1. Cayenne Powder (100 mg)

Cayenne contributes to the overall process of thermogenesis as the heat from it helps raise the core temperature of the body, catalyzing the effects of the already thermogenic green tea extracts. The combined effect of these two natural elements activates the body for efficient fat burning.

  1. Glucomannan (1800 mg)

This is a unique soluble fiber that is extracted from the root of the Konjac plant, which is known to be a very potent and stable appetite suppressant. It works by absorbing excess fat and fluid and swelling up to form a gel-like substance that makes you crave less junk food at odd hours. It helps the body get into a proper diet by regulating appetite that makes you follow a healthier way of life.

  1. Caffeine Anhydrous (350 mg)

Caffeine, as we all know, is a powerful stimulant. The supplement provides it as an ideal dose that heightens the effects of the core ingredients contained in the product to give you a sustainable energy boost.

  1. Vitamin B6 (5 mg)

This fundamentally helps with the management of glucose in the body apart from being an important element in several processes of the body. Vitamin B6 also helps in the stimulation of thyroid gland as well as the suppression of cravings, thereby contributing to efficient weight loss.

  1. Vitamin B12 (10 mg)

This helps to break down the macronutrients such as proteins, carbohydrates, and fat in the body, aiding the process of assimilation. This contributes to the generation of new muscle mass and repair muscle fiber. Similar to Vitamin B6, it stimulates and regulates the functions of the thyroid gland as well.

  1. Zinc (10 mg)

One of the essential micronutrients, Zinc, works as a powerful fuel and booster for intense workout sessions. It is a testosterone booster as well and contributes significantly to the process of protein synthesis. And, hence, it serves to be an ideal element for weight-loss plans.

  1. GTF Chromium (100 mg)

It regulates the level of glucose in the blood and aids in shedding excess weight, helping in the generation of muscle mass.

  1. Black Pepper Extract (10 mg)

The extracts of black pepper increase the bioavailability of the other ingredients in the formula, enabling your system to assimilate more and more of it. It heightens the effects of these ingredients and, hence, the overall formula, for that matter.

  1. Green Coffee Extract (100 mg)

The extracts of unroasted, raw coffee beans contain high levels of Chlorogenic acid. This slows the rate at which your system absorbs fat from what you consume. It also lowers the levels of glucose in your liver.


As per the directions on the outer cover as well as on the bottle of the supplement, Instant Knockout requires for you to take one pill four times a day.

  • Take the first pill right after you wake up before you have your breakfast.
  • Take the second pill between your breakfast and lunch,
  • Take the third pill an hour after your lunch
  • And finally, take the fourth pill an hour before you have your dinner.

You can take the supplement with water. Sticking to a well-balanced diet and regular exercise is highly recommended to achieve the best results.

What are the side effects?

Instant Knockout contains natural ingredients that include plant extracts as well as some minerals and vitamins. This makes it safe for consumption by anyone.

However, do make sure that you are not allergic to any of the ingredients contained in it, in which case you should not take it. If you feel any discomfort or adverse effect on your health while on the supplement, discontinue use immediately and seek medical help.

The supplement contains stimulants such as caffeine and green tea in smaller quantities. However, if you’re sensitive to stimulants, then do not take this product.

Pregnant women should not take this supplement. Also, if you have a specific medical condition or on certain prescribed medication, then avoid consuming this product.

What could have been better?

Even though the supplement has fortunately shown positive results in Joey’s case, there are a few things, which, in our opinion, could have been better.

First off, the daily dose of the supplement stands at four pills, which is quite a lot. It also increases the chances of you missing out on a dose if you’re not that mindful of the routine all the time.

Secondly, even with that many number of pills a day, the supplement takes its own sweet time to show effects, and the results vary from person to person.

Finally, the product has no mention of EGEC. It is a bit on the expensive side and also, not a vegan product.
