Real Instant Knockout Fat Burner Review

“The Fat Burning Secret of Pro MMA Fighters”

I train boxing twice a week and BJJ once. I’ve always been a fairly chunky guy, and even with so much training would often have trouble keeping weight off. It’s not always easy and not always fun, but it’s always worth it in the long run.

John Dodson, Diego Sanchez and Greg Jackson

I’ve tried a load of supplements and have to say that one has really stood out when it comes to keeping my fuelled whilst keeping my weight down.

Instant Knockout is a fat burner created by Roar Ambition. This product has been used by a number of professional fighters, namely one of the original champions of the Ultimate Fighter, Diego Sanchez and coach at the Award Winning JacksonWink academy, Greg Jackson.

Similarly to the companies other product we have reviewed, TestoFuel, Instant Knockout uses 10 natural fat burning ingredients that will help you achieve your weight loss goals.

What Does Instant Knockout Promise?

  • Boosted Metabolism
  • Reduced Hunger
  • Increased Energy

Instant Knockout stands out as the most premium, well researched fat burner on the market at this stage. We have experienced first-hand the success you will have with the 90 day supply of this product.



The ingredients in Instant Knockout are completely natural. What is more exciting is that the formula is updated according to the latest scientific research, so you know you are always getting a fully up to date fat burner.

Caffeine Anhydrous

Don’t buy a fat burner without this. Caffeine is a great natural fat burning ingredient. It’s been thoroughly tested through time and delivers proven results. Not just where energy is concerned, but also with speeding up the bodies metabolism and keeping it burning fat. You need a supplement with an even dose of caffeine to get the best results. High doses in one go can cause crashes and sleeplessness, so be aware of this.

Green TeaInstant Knockout Ingredients

A fantastic and proven fat burning ingredient. Green tea has been used for health reasons for thousands of years. This ingredient stimulates your metabolism through ‘catechins’, which have been proven to stimulate your body to use more fat as fuel. It’s these properties that help Green Tea to help melt away unwanted fat. You know you’re in good hands with this ingredient.


Is the main ingredient for appetite reduction in Instant Knockout. This is a naturally occurring, water soluble dietary fiber. When it reaches the stomach and comes out of the capsule Glucomannan expands, causing you to feel more satisfied and less tempted to cheat on your diet or eat extra calories at meal times. We were a little skeptical of this, however have read various studies supporting it’s use.

Cayenne Pepper

Very happy to see cayenne pepper in this supplement. You know when you eat something spicy you sweat? Well this is the same reason good fat burners will always have Cayenne pepper in.

The cayenne heads down to your stomach and actually heats up the body, causing it to burn calories whilst trying to cool itself down.

There’s a special ingredient in Cayenne called capsaicin which can suppress appetite and has been proven by research to cut down your stored body fat. This ingredient can cause some stomach upset if dosed over 150mg through the day. Bare this in mind when choosing a fat burner.

GTF Chromium

GTF chromium is a trace mineral essential to your bodies regular function. It’s included in fat burners as it helps the body regulate blood sugar levels, which will curb your cravings. Also, when tested, chromium was found to increase lean body mass and reduce fat mass in patients on a low calorie diet. An excellent ingredient.

Vitamin B6

Vitamin B6 is widely known for it’s amazing effects on the bodies metabolism. Whats more, this vitamin also helps with hormonal control and aids immune function. B6 in the body helps with the breakdown of amino acids too, ensuring that muscles are absorb high amounts of protein and absorb the amino acids correctly.

Other active ingredients: Zinc, Green Coffee Extract, Vitamin B12, Black Pepper Extract.

Whats the cost?

Whilst Instant Knockout isn’t the cheapest fat burner on the market, we fully recommend spending a little more on it’s premium price tag.

The cost of one box is $59. There are fat burners that are more expensive and far less effective than this.

What’s really exciting about Instant Knockout, is it’s use of natural ingredients. Very few other fat burners we’ve used offer such good results with such safe ingredients.

90 Day Money Back Guarantee – Only Supplement to do this?!

This is crazy, but Instant Knockout offers you a 90 day money back guarantee. If you try the product and find you don’t get the results, then you can actually get a refund.

This offer also comes with a free box.  The cost of a 90 day supply is $185.00. Worth it if you are actually serious about shedding some pounds.

Real Instant Knockout Review Conclusion

We have had extremely good results from this supply. Importantly it wasn’t a one off either. We know of 2 amateur fighters that used the product to cut weight after seeing Diego Sanchez used it and found it extremely effective.

What’s more there are a load of testimonials on their website. Instant Knockout is the real deal and will certainly help you achieve your weight loss/cutting goals.
