The Professional MMA Fighter Diego Sanchez says he used Instant Knockout and shredded down from 190lb / 86kg to 145lb / 65kg. That’s an express cut of 45lb / 21kg using this product. And Diego Sanchez isn’t the only pro to use Instant Knockout to get their results.

They are; Green Tea Extract, Cayenne Pepper Seeds, Glucomannan, Caffeine Anhydrous, Vitamin B6, Vitamin B12, GFT Chromium, Zinc, Piperine and Green Coffee Bean. Read-on for a detailed breakdown of these.

Trustworthy formula:

Why did we say no dirty secrets? A lot of Fat Burners have cryptic proprietary blends meaning you can’t know exactly what you are buying. If even your unhealthy bag of chips can tell you what crap is inside why don’t other products?

There are obviously a lot of amateur products on the market, but we are much happier not taking a risk. Instant Knockout lists all its ingredients on the side so you know what you are paying for, and, if it’s working, you know why. Which leads us onto its next one-two combo…

In the words of of Instant Knockout themselves, “We are confident that you will be satisfied with your purchase of Instant Knockout. As a result we will refund your purchase if you haven’t experienced any results.”. That’s right, they will refund you if you have tried the product for 90 days and see no results.

So you don’t even have to take our word for it, they are so confident in their product they are putting their money where their mouth is. I wonder how many of the others are so fearless to offer this…

So that’s; MMA tested, 100% natural, 100% trustworthy and risk-free. Are you starting to see why we love it so much? Now let’s see exactly how it does it and look at the contents in more detail.

How it works

At its heart Instant Knockout is a scientifically tested and proven Fat Burner used unlock your body’s own ability to shred fat. It makes sense, your body wants to store fat. In the past you didn’t know when you might eat again and so storing excess fat was necessary for your own survival. But, we are now in the new and unique situation where we can eat whenever we want, however, our body doesn’t know this and needs help switching modes from store to shed.

This is where Instant Knockout’s research comes in. Instant Knockout is designed to speed-up your metabolism to get your body working for you and not against you in this modern world. Let’s look in detail at its ingredients, remember not something we can do with all products, and see how it achieves champion results.

The Ingredients

Cayenne Pepper Seeds:

It doesn’t take much imagination to figure-out how this one works. Nature’s radiators. Naturally raising your body’s base temperature in an instant.

The specific way it does this is with its active ingredient Capsaicin, a proven thermogenic. This compound starts to heat up your body and your body instinctively responds to start cooling you down thus burning calories. This ingredient requires zero effort, and, just as importantly, zero burning mouth as all this goes on behind the scenes. Much better if you aren’t a fan of eating Ghost Chilies daily.

Green Tea Extract:

This gentle giant is packed full of the potent and proven antioxidant Epigallocatechin Gallate (EGCG), a type of catechin. These increase your core body temperature after consuming food, helping reduce your body weight by reducing your body fat in a safe and biologically natural way.

There are numerous completed and ongoing studies which clinically show the benefit EGCG has on fat loss and so it’s obvious why it’s a fundamental ingredient in Instant Knockout.


With the burning of calories taken care of, this supplement also combats the other enemy of weight, the consumption of too much food. Instant Knockout contains a natural water-soluble dietary fiber, Glucomannan, which naturally makes you feel fuller for longer.

Long known in Asia, this stomach filler actually expands when it comes into contact with water, this supports your own ambition to consume less and shred more even when your own willpower is failing.

Caffeine Anhydrous:

The reduction in food intake which is part of any fat burning obviously has an affect on the amount of energy your body has, but, you still want to be able to make gains at the gym and not go backwards.

Caffeine Anhydrous

That is where the correct dosage of caffeine comes in. Too little and it won’t make a bit of difference, too much and you will be shaking wreck. Instant Knockout contains 300mg of Caffeine Anhydrous to give you the focus and boost at the gym even when shedding the pounds so you can continue throughout your cut, and for longer.

Vitamin B6:

Vitamin B6, also often listed as Pyridoxine, is a fundamental part of a balanced diet.

Without this nutrient you can start to sleep poorly, not regulate your mood and negatively affect your metabolism. All of these can restrict your will to stick to your diet and your new healthy regime. (remember you and your body are in this together). Instant Knockout contains Vitamin B6 to ensure your mind and body stay on track even when you are struggling.

Vitamin B12:

Also known as Cobalamin, Vitamin B12 is a fundamental part of red blood cell production with which your body uses to transport oxygen around your body.

This is a key component of aiding your metabolism, increasing energy levels, aiding the nervous system and contributing to your overall health. An obvious cornerstone of any good Fat Burner.

GTF Chromium:

Glucose Tolerance Factor (GTF) Chromium is the bedrock of the best Fat Burners.

GTF Chromium Mineral

It’s easily absorbed by your body and contributes to better insulin levels and improving cholesterol. It has been linked to reductions in blood sugar levels and increased athletic performance.


An inferior level of zinc can significantly derail even the best attempts at fat loss.

Zinc commonly found in Brazil Nuts

Apart from low levels being linked to poor cognition, circulatory problems and increased risk of some illnesses, it aids hormone production, cell growth and cell repair.


The extract from pepper, long used in traditional medicine, has been scientifically shown to reduce body weight, body fat (Lipids), reduce bad cholesterol (LDL and VLDL) while increasing good cholesterol (HDL).

Black Pepper Extract

This is another ingredient, along with Cayenne Pepper Seeds, which falls into the category of too good to miss, but too hard to consume in your regular diet due to their potent flavor and taste.

Green Coffee Bean:

Currently one of the hottest additions to any new Fat Burner, this ingredient is a direct extract from unroasted coffee beans.

Green Coffee Bean

Unlike consumer coffee beans, these don’t lot go through the roasting process and lose their main active ingredient, Chlorogenic Acid. Studies have shown Chlorogenic Acid inhibits the absorption of fat and carbohydrates and also reduces the amount of fat stored in the liver. A fantastic way to round off the perfect 10 of ingredients.

How to take it

At it’s core Instant Knockout aims to increase your metabolism and reduce your hunger. For this they have worked-out that you should take 3-4 capsules daily.

These are spaced out to evenly combat all the enemies of Fat Loss throughout the daily rather than in one go. This isn’t a laxative weight loss pill after all. This easily slotted into our usual routine without a break in our usual rhythm at all.

Side effects

Instant knockout themselves state that it’s side-effect free. We can vouch for this as throughout our time testing this fat burner we’ve never experienced any problems with the supplement.

The only thing that might be of concern to some people is the fact this (and every other fat burner out there) contains caffeine.

If you have ever drank a cup of coffee, tea, and a pre workout before, then chances are the low amount of caffeine in Instant Knockout will not cause you any issues.

However, if in doubt, or if you have any pre-existing medical conditions you suspect may cause a problem, we suggest you consult a doctor.

The Negatives

Having a higher quality of product always comes with a higher price tag that only those serious about shifting their excess weight may be willing to pay. But if you’re serious about losing weight, then paying a little extra will go a long way.

What we did find slightly annoying was the fact we had to take 4 pills per day everyday.

While it was difficult at first, we found that the benefits greatly outweighed the negatives of this regular dousing protocol.

Another thing that might put people off is the fact you can only buy it direct from their online store.

This could seem like a negative, but it actually prevents people from trying to reproduce their formula and sell it online in other places such as eBay.

We personally enjoy a cup of coffee, have the desire to pay a little more for a quality product and preferred dealing direct with the company, so no complaints here.

Where to buy it

One of the key things stated by Instant Knockout on their website is that it’s a premium product which they deliver at the lowest price they can without losing quality. For this they say that they only sell direct and offer no bargain basement sales at an point.

We found that the order process direct from them was as quick and easy as any other online retailer. Also, their customer service was particularly helpful in answering the delivery questions we had for them. We actually preferred the more human feel to their custom service than we get with some of faceless retailers.

The Instant Knockout Store


Instant Knockout is by far the clear winner in this category. With its tackling fat loss at both ends of the problem, reducing calorie intake and increasing calorie burning, we could not be happier with this product.

The supplement was safe, had no side effects, was easy to take and fantastic value for money. We really cannot say enough good things about this product.

It will take some attempt to knock this off the top spot this year.
