Instant Knockout Review: Say Goodbye To Unsightly Stubborn Fat for Good

You’ve got cleavage, and shirtless beach walks have become a nightmare.

Worse still, your protruding belly is sending warning signals to your liver and heart.

Do not worry, you are not alone: about 30 percent of men develop man boobs in their lifetime.

Unsurprisingly, Americans are spending billions of dollars trying to get a flat tummy.

But, you don’t have to hide behind baggy shirts anymore.

Roar Ambition has a solution to your man boobs and belly fat: a fat-frying Instant Knockout fat burner.

Is it the best fat burner in the market?

In this Instant Knockout review, we will tell you how it helps the body burn fat like professionals.

What Is Instant Knockout?

Instant Knockout is a top fat burner for men that was initially formulated to assist MMA fighters and Pro Boxers in burning fat before their mega-fight.

It helps increase your body’s ability to burn fat by boosting metabolism, supercharging your workouts, and suppressing your appetite.

It merely makes the body burn more stored fat while utilizing the fat you are consuming, quite intriguing, right?

Professional athletes, including Greg Jackson, former UFC champion Diego Sanchez and John Dodson III, are using Instant Knockout to burn and keep fat off.

About the Brand

Instant Knockout is designed by Roar Ambition, a company based in Leeds, UK.

It was started in 2012 by Robert Parker.

Roar Ambition mainly targets testosterone boosting and fat burning supplements. Lately, they have added a nootropic in their product range.

They are behind the famous TestoFuel (T-booster), Hourglass fit (women fat burner), 4 Gauge (pre-workout), Prime Male (T-booster), and Hunter (premium-T-booster, focus, and fat burner). 

They state that their products are clinically researched with up-to-date formulas.

Besides, the product range is well endorsed by professional bodybuilders and athletes.

How Does It Work?

If you are interested in stripping off body fat safely, understanding how each dietary supplement works should be on top of the list when it comes to things to watch out for.

You do not want to put anything in your body just because it promises to help you burn fat.

So, does Instant Knockout really work?

Yes! Instant Knockout attempts to stimulate thermogenic actions. In simple terms, it increases internal body heat through accelerating metabolic reactions, which in turn, burn fat.

It blends 10 natural ingredients that employ three approaches to target fat loss.

Boosts your metabolism

Your body continually uses energy despite what you are doing. If you are doing your morning cardio or simply curled up on the sofa, your body needs the energy to survive.

Instant Knockout increases your metabolism, allowing the body to burn more fat even at rest.

 A higher metabolism means faster fat burning.

Increases energy

This fat burner is enriched with powerful stimulants that keep you supercharged during your workouts.

Suppresses appetite

If you are serious about weight loss, you know that frequent hunger pangs can be a nuisance and encourage more fat storage.

Instant Knockout inhibits hunger pangs preventing snacking between meals.

Instant Knockout Benefits

Obesity is ranked among the most crucial public health problems globally.

The World Health Organization estimates that 2.7 million individuals will be overweight by 2025, sad!

If that is not enough, millions of individuals die from obesity-related conditions, including heart diseases, some types of cancer, diabetes, and stroke.

Instant Knockout can help you lose weight, attain muscle definition, and improve your quality of life.

It blends together natural ingredients, which we will get into below, that have a strong scientific backing.

From our conversations with other users and some experts, Instant Knockout has managed to combine ingredients that offer the following benefits.

  • Weight loss
  • Reduced abdominal fat
  • Reduced appetite
  • Increased insulin sensitivity
  • Reduced cholesterol levels
  • High T-levels
  • Improved vascular and metabolic health

Ingredients List

instant knockout ingredients

Instant Knockout has been clinically researched by scientists and nutrition experts to create an up to date formula that meets safety criteria.

This is not just some random stuff put into a container like many supplements in the market.

First things first, we have consulted on each of the ingredients from dieticians, and we want you to understand the intricacies of Instant Knockout before you buy it.

Let’s dive in.

Green Tea Extract

Green tea has been seen to have potent fat-burning properties.

A 2009 study on the effects of green tea on weight loss showed that catechins significantly lowered body weight and promoted positive weight management after weight loss.

It contains catechins and caffeine that speed up metabolism and promote excess fat breakdown.

Green Coffee Extract

Green coffee has been widely used for weight loss.

It contains chlorogenic acid, which boosts metabolism in the body, forcing it to burn stored fat for energy.

Again, it is a powerful appetite suppressant that controls cravings preventing snacking between meals and overeating.

And that’s not all; it burns fat, removes bad cholesterol from the liver, and reduces insulin spikes by inhibiting carbohydrate absorption in the intestines.

A review published in Gastroenterology Research and Practice showed that green coffee promotes weight loss.

Cayenne Powder

Cayenne is rich in capsaicin-its active ingredient that increases metabolism-it boosts the heat in your body, making the body burn more calories than usual.

A study published in the European Journal of Nutrition showed that individuals who took a cayenne rich breakfast burned at least 51 percent more calories compared to those who didn’t.

Interestingly, capsaicin has been seen to reduce hunger by lowering the production of ghrelin -the hunger hormone.


Glucomannan is a water-soluble dietary fiber that is derived from the konjac root.

It is a popular choice among individuals looking to lose weight.

Glucomannan absorbs water in your stomach, taking up most space; this promotes feelings of fullness, thus lowering your food intake.

Besides, it reduces the absorption of carbohydrates and cholesterol, thus enhancing weight loss.

A study published in the International Journal of Obesity showed that individuals lost about 5.5 pounds in 8 weeks following Glucomannan supplementation without any other changes in their diet.

Caffeine Anhydrous

Caffeine anhydrous is popular in boosting weight loss and athletic performance.

It is a stimulant that increases energy-boosting fat oxidation.

Besides, it increases your focus and alertness during workouts and reduces fatigue.

A study published in the American Journal of Clinical Nutrition showed that 100mg caffeine increases resting metabolic rate and induces thermogenesis, enhancing overall energy expenditure.

This means that Instant Knockout will offer extra benefits; it contains 300mg. But, if you are sensitive to caffeine, this is maybe a drawback.

Black Pepper Extract

Black pepper is a popular spice globally.

It increases blood-sugar metabolism, lowers cholesterol, promotes gut health, and reduces appetite.

Besides, it increases the absorption of nutrients in the body. Hence it boosts the bioavailability off Instant Knockout.


Zinc is one of the essential minerals in the body.

It increases the production of testosterone in the body-the hormone responsible for protein synthesis and fat metabolism.

Besides, zinc increases the conversion of fat, proteins, and carbohydrates into body fuel to support your workouts.

A study published in Endocrinology shows that testosterone reduces fat mass in men.

GTF Chromium

GTF Chromium is a trace element that helps to maintain healthy blood sugar levels.

It regulates insulin-the the hormone that manages how the body stores carbs.

Besides, it boosts metabolism, increases energy levels, and suppresses your appetite.

Vitamin B12 and B6

Instant Knockout includes vitamin B12 and B6 for your energy production and mental alertness during workouts.

Instant Knockout Real Users Reviews

We do not recommend just looking at a single review to decide whether it is worth it.

So, we did some research online to see what users had to say.

Here are some Instant Knockout reviews.

I started my weight loss six weeks ago and have been taking Instant Knockout for four weeks. Also, I am on a high protein and low carb /low-fat diet.

I have gone from 109 kg to 104kg […] I have seen a visible difference in losing fat, my belly fat is no longer solid and jiggles about, and my clothes are becoming extremely baggy and have had to purchase a new belt in the last four weeks.


Instant Knockout is one of the best that I’ve used. The glucomannan stops me from being so hungry, and the caffeine, green tea, and cayenne give me the extra energy that I need to work out.
