Instant Knockout Fat Burner Review – The Ultimate Appetite-Buster?

While the marketing might be focused on the MMA market, everyone can take advantage of this unique fat burning supplement.

Mixed martial artists and MMA enthusiasts in general are people who are serious about fitness, so when they start taking interest in a product, we tend to pay attention.

We sometimes get free items for review purposes and can obtain a commission for any sales of those products via links on our site.

That’s why we’re talking about Instant Knockout, a highly rated fat burning product that could help with your weight loss program, if taken with care.

That’s definitely a bold claim, but we’re confident in what we say, and by the end of this review, hopefully you’ll agree. Read on to learn all about the brand behind the product, the ingredients involved, the cost, the effects of the product, and some simple pros and cons.

The first thing to know is that Instant Knockout contains a high amount of glucomannan, a key ingredient that is one of the best appetitte suppressants around. As your appetite lowers, you have less desire to eat, so you take less calories in and therefore can lose weight more easily. It’s simple science and it works well, as long as you’re careful about the foods and drinks you consume.

As well as containing lots of glucomannan, this fat burner is also comprised of green tea, green coffee, cayenne pepper, and black pepper.

Instant Knockout Name

The first thing you notice about Instant Knockout’s branding is that it really goes in heavily on the fighting theme. This is a product that is purely aimed at MMA athletes and hardcore fighters, and we can see this from the product’s name and its packaging. A lot of combat sports, like the big MMA tournaments, have strict weight classes to make fights even. This means that big guys fight big guys and smaller guys fight smaller guys, so weight is a big deal in the fighting world. Fighters have to be at just the right weight to suit their class, otherwise they won’t be allowed to take part in fights.

This is why Instant Knockout can be so useful in the MMA world, and the brand even has testimonials from leading MMA figures, with one fighter even saying that the product helped him lose over 40 lbs. However, even though Instant Knockout is marketed towards fighters, it can be useful for so many more people! Countless people want to lose weight and Instant Knockout can help with that. You don’t have to be trained in jiu-jitsu or kickboxing to get the best out of this product. It works for both men and women too.

Sometimes, the male and female bodies can make fat burners work differently. However, Instant Knockout is very similar to Leanbean in terms of its ingredients. Leanbean is one of the top fat burners for females on the market, so it’s easy to see how Instant Knockout can appeal to ladies, as well as men.

The Science Behind Fat Burner Products

When it comes to fat burners, we can typically place them in one of the following categories:

1.Lower Appetite Lowers your appetite to reduce your calorie intake.

2. Thermogenesis  Speeds up the calorie burning rate, even when you’re resting.

3. Reduced Absorption Rate Causes your body to absorb fewer calories.

4. Higher Fat Breakdown Rate Triggers the body to burn off more fat for energy.

Don’t forget the importance of dosage! We always compare products’ recommended dosages with studies to ensure that they’ll actually work.

Ultimately, even the best fat burner in the world will only help you burn off around 200-300 extra calories. This is why it’s so important to watch what you eat and follow a smart diet plan while using fat burners if you want to truly see real results and lose a noticeable amount of weight.

Put simply, if you burn more calories than you consume, you’ll lose weight. You can do this without any fat burner at all, but fat burners will make the process go more quickly and easily. Just be sure to check with your doctor before taking any new products.

The Advantages Of Instant Knockout

Now let’s take a look at the top ingredients contained in Instant Knockout:



On the ingredients list for Instant Knockout, Glucomannan is the star of the show. Produced from part of a special tree grown only in Japan, glucomannan actually expands inside the stomach, thereby reducing your appetite and lowering your hunger levels.

A study from the International Journal of Obesity showed that just 1,000mg of glucomannan taken each day resulted in greater weight loss for obese people, without making any adjustments to what they eat. Instant Knockout contains a total of 1,800mg of glucomannan, so it can definitely have a big impact on your weight loss plans.

How about side effects? Well, since glucomannan absorbs water in the body in order to expand, it can make you a little thirsty, but that’s the only common side effect associated with this ingredient.



Caffeine has been proven in studies to increase the breakdown of fats and thermogenesis. Scientists believe that this is because caffeine boosts our adrenaline levels, and adrenaline makes us burn off fats more quickly.

A high profile study showed that just 100mg of caffeine helped people burn off up to 150 additional calories. Instant Knockout contains three times that amount (300mg) so can be highly effective, but some people don’t tolerate or enjoy caffeine all that much.



This fiery spice has also been linked to both the breakdown of fats and the process of thermogenesis.

Several studies have shown that cayenne can help people burn off around 100 extra calories.


Green tea

Green tea is a very healthy ingredient that helps with the breakdown of fats.

A study in American Journal of Clinical Nutritionshowed that fat oxidation increased by 17% with 366mg of EGCG (a key ingredient in green tea). Unfortunately, Instant Knockout’s ingredient list doesn’t show how much EGCG it contains.


Green coffee

Studies have linked green coffee with a lower calorie absorption rate, effectively saving people up to 200 calories each day.

The key ingredient in green coffee is chlorogenic acid, but we don’t know exactly how much chlorogenic acid is in Instant Knockout.


Black pepper

As well as boosting fat oxidation, black pepper also helps people absorb more healthy vitamins and minerals from their foods.

Additional Ingredients

Instant Knockout is also loaded up with B-vitamins that can raise energy levels and even improve focus:

“A lock Vitamin B-12 can lead to tiredness, shaking, reduced blood pressure, and general weakness. High amounts of B-12 can boost your energy levels and raise your game.”

Vitamin B6

Vitamin B12

In reality, this statement is true, but only for people with a true B-vitamin deficiency. Taking high amounts of B-vitamins won’t really give you crazy energy levels or supercharged focus and concentration. The product also contains zinc which can aid with the generation of testosterone. Science backs this up, but lots of zinc won’t suddenly raise your T levels by very high amounts, so the claims are somewhat exaggerated.

Can You Combine Other Products with Instant Knockout?

The Instant Knockout brand says it’s perfectly fine to use other supplements alongside this one. However, you still need to be careful. Don’t forget that Instant Knockout contains a whole lot of caffeine, so if you add on other stimulants while using it, you could have some negative consequences:

“Too much caffeine can lead to several side effects such as jitters, headaches, nausea, and other problems. To avoid discomfort, we don’t recommend other supplements that contain stimulants to be taken with Instant Knockout.”

Instant Knockout Dos and Don’ts


  • Have a good diet
  • Exercise regularly to increase calorie burn
  • Follow the recommended dosage
  • Use for at least two months


  • Combine with other stimulant supplements or products
  • Take the capsules too late in the evening as the caffeine might keep you up

Instant Knockout Price

Looking across the fat burner market, we can see a lot of different products and price tags. In general, you can expect to pay around $1 per day for a typical fat burner. So how does Instant Knockout compare?

Often, this brand offers big bulk deals, letting you buy lots of bottles all at once for a discounted price. This means you’ll pay around $45 per bottle, which equates to $1.50 per day.

If you don’t take advantage of the deals, you’ll probably have to spend up to $60 on a bottle, which offers a month’s supply of capsules, resulting in a cost of around $2 per day. So Instant Knockout isn’t the cheapest option out there, but it justifies its price tag by being more effective than a lot of the competition.
