According to the Centers for Disease Control and Prevention, around 49% of Americans surveyed between 2013 and 2016 claimed they were trying to lose weight. Most of them try to limit their calorie intake and increase workout efforts but end up not seeing any noticeable effects. 

Now, fighters especially need to burn their extra body fat fast and safely to improve performance and meet the weight limitations intended for their category. A simple change in diet does not always work for them. 

This is where Instant Knockout, a fighter’s fat burner, comes into play.

A Fat Burner For Those With A Fighting Spirit

Instant Knockout is an effective fat burner manufactured by Roar Ambition. It can aid athletes with weight loss, muscle growth, and fat loss. Although it was initially created for MMA fighters and professional boxers, its blend of all-natural, medically-backed ingredients can also benefit regular folks looking to gain some muscles and lose weight. 

Instant Knockout is suitable people who aim for a slim, six-pack flexing stomach, toned chest, ripped and defined shoulders, and carved legs. It includes a blend of nine natural fat-burning components that have undergone extensive studies to ensure safety and optimal effects. It is the only weight-loss supplement trusted and recommended by legendary MMA Coach Greg Jackson.

Instant Knockout has long been the choice of top-tier professional athletes. It has helped them stay fit and maintain their competitive edge. Mentioned below are a few big names who have successfully used instant Knockout.

Is It Just For Men?

Instant Knockout is not just intended for men — ladies who seek to get similar effects may also use it without any issues. The goal is to help you eliminate extra fat, regardless of gender. The carefully chosen, tested ingredients of Instant Knockout work the same for both men and women. 

What Benefits Can Users Expect From Using Instant Knockout?

Instant Knockout contains ingredients that can burn body fat and help you lose weight. It also controls the processes that produce fat in the body. Fat metabolism produces energy, which is used to power different body parts. 

Green tea extract (catechins) can help improve thermogenesis and regulate hormones. Thermogenesis is a chemical process that allows your body to generate heat and burn calories as you digest food. Increased thermogenesis improves your ability to burn calories quickly and ultimately shed weight efficiently.

Cayenne pepper seeds, an ingredient found in Instant Knockout, can potentially improve insulin sensitivity. It may considerably impact insulin, resulting in more energy and less fat. The American Journal of Clinical Nutrition reports that insulin sensitivity lowers fat and increases energy levels. 

Another significant component, glucomannan, reduces the concentration of harmful cholesterol (LDL) in the body. Glucomannan also suppresses appetite. Your body can absorb it very quickly and it makes you feel full for longer.

Users also experience a significant increase in physical and mental energy. The combination of caffeine, L-Theanine, and green tea supports your mood and concentration, so your mental health is not compromised during your weight-loss journey. 

Ingredients That Are Combined To Create Instant Knockout

Roar Ambition uses the highest-quality natural ingredients while manufacturing Instant Knockout. They include:


Glucomannan is a dietary fiber that decreases our desire for food and the feeling of hunger. According to the International Journal of Obesity, it suppresses appetite and has been proven to help with weight loss in clinical trials. 

Glucomannan accelerates weight loss by helping you avoid factors that lead to overeating and excessive snacking. It is a soluble fiber with a long-chain carbohydrate composition, which makes you feel full for a long time. 

Green Tea Extract

Black Pepper Extract

Piperine, a substance found in black peppers, helps improve metabolic function and reduces the buildup of fat in the body. A study published by the Indian Journal of Pharmacology shows that piperine metabolizes fat and reduces fat levels. 

It functions as a switch for two receptors in your body, TRPA1 and TRPV1, which, when active, increase energy metabolism and can prevent the creation of fat cells.

Cayenne Powder

Cayenne pepper is a well-known thermogenic. It stimulates your body's metabolism and starts the burning process. The primary component, capsaicin, has been proven to improve fat oxidation and boost energy expenditure, according to Bioscience Reports.

Caffeine Anhydrous

Caffeine has a variety of advantages. Studies have shown it supports aerobic exercise, power production, running capacity, and more. It activates the central nervous system, which sends signals to fat cells, instructing them to begin breaking down fat.

As per the Critical Reviews in Food Science and Nutrition meta-analysis, caffeine consumption encourages weight loss and reduces BMI and body fat.


L-theanine smooths out jitters and stops any crashes when paired with coffee. Journal of Medicinal Food study supports the idea that it helps people relax and stabilize when crashing from other stimuli. Additionally, it can help improve the quality of your sleep, leaving you rested and prepared to accomplish your goals the following day. 


  • Vitamin B6 

    Your body uses vitamin B6 to convert food into energy. According to clinical studies, Vitamin B6 can raise your dopamine levels, helping you stay motivated and focused during your next workout.

    Additionally, it can also raise your serotonin levels, improve your mood, and help you become regular with your exercise while increasing your chances of reaching your weight-loss objectives.

  • Vitamin B12

It also has the unique ability to boost your energy, focus, and mood, all of which are factors when trying to lose weight. It is one of the essential vitamins needed to maintain a healthy nervous system. A 2013 research associates low vitamin B12 levels with obesity. 

  • Vitamin D3

The International Journal of Preventive Medicine states that your Body Mass Index (BMI) and vitamin D levels correlate and that vitamin D helps you lose weight.
