Review Overview – What does Instant Knockout Do?

Quick Overview: Instant Knockout is a fat burner that was originally designed for professional MMA Fighters. It is a drug-free, all natural stimulant which helps athletes cut fat fast, and it’s the best ingredient combination I’ve ever used.

Using all natural ingredients and no proprietary blends, Instant Knockout claims to offer the following benefits:

  • Cut Fat – Using complex thermogenic compounds, Instant Knockout raises your metabolism and body heat encouraging the body to burn more calories than usual.
  • Boost Energy Levels – The stimulants in this product raise your energy levels to keep you focused and motivated during workouts when on a low calorie diet.
  • Suppresses Appetite – Packed with the fibrous root glucomannan (read more about that here), the fat burner swells in your stomach and cuts down on cravings.

Instant Knockout is currently being used by MMA stars Diego Sanchez and John Dodson who both swear by its effects. Sanchez in particular who has cut 25lbs in 5 weeks using the product (Although this is with dieting and exercise in line with a competitive athlete).

You can read our personal results with Instant Knockout at the bottom of this review.


How does Instant Knockout work?

Quick Overview: Instant Knockout contains a range of effective and clinically proven thermogenics, appetite suppressants and energy boosters. It has 4 servings a day, so your body is constantly supplied with what it needs to burn fat round the clock.

Running through the ingredient panel, we were very impressed with what we saw.

A lot of the ingredients agree with our findings on the best fat burning ingredients out there, so our expectations were high.

Here’s the full ingredient list:instant-knockout-ingredients

Green Tea grabbed our attention first, IKO has 500mg of it per daily serving…

This is hands down the best fat burning ingredient you can come across if you want to stay on natural supplements. An everyday cup of this stuff can burn 5.7g a fat at a time. It’s a caffeinated herb, so you’ll definitely get an energy kick from it, but more importantly is how it works in the fat burning process.

The catechins in the green tea react with the body to increase the norepinephrine in the body. Norepinephrine is the fat burning hormone and will give you the thermogenic boost you need to burn more calories. It also helps raise metabolism which will make some significant differences.

Then it was the Green Coffee Bean…

Not a lot of fat burners use Green Coffee Bean, but IKO isn’t just any fat burner. Although it lacks the caffeinated angle of its roasted counterpart, Green Coffee Bean contains chlorogenic acid which helps with the breakdown of glucose in the liver.

Removing the glucose, your body looks for another energy source to regulate itself, and the next in line is fat cells. This is a more direct way of burning fat and is definitely appreciated in this supplement.

There’s also 300mg of Caffeine in this fat burner…

Not only is this ingredient a proven stimulant, but it also helps to boost the body’s metabolic rate. That all aside, the main use of this nutrient in Instant Knockout is to boost energy during sluggish days on low calorie diets.

Caffeine has been proven to increase power output in athletes during their training in both endurance and power. The caffeine here should help maintain your lifts during your cutting phase and ensure that you maintain your strength when you get towards the end of your cut.

Glucomannan completes this product…

The konjac root is known for its fibrous properties. After ingestion the glucomannan swells in the stomach and makes you feel fuller. In doing so you crave less food and staying on track with your diet.

These benefits have been scientifically proven and you can read all about them over at our ingredients page, along with a few studies.

Thermogenesis is guaranteed with the use of cayenne pepper…

This hot chili is a sure-fire way to keep your thermogenesis topped up and constantly working throughout the day. The capsicum in this nutrient raises your core temperature, this forces a regulating process to cool down.

This is great as it results in the expenditure of more calories – you can up your caloric deficit even while resting!

Those were our highlights but Instant Knockout contains a lot more beneficial ingredients.

Side Effects?

Being a totally natural product, Instant Knockout has no dangerous side effects.

One thing we will say about it however is the caffeine kick, although manageable (and enjoyable!) it can give you sleep problems when taken a few hours before bed. So make sure you space out those servings in a way that avoids it interrupting bed time.


What I experienced

Quick Overview: I took Instant Knockout for 3 months and dropped 9% body fat. It’s perfect for anyone who wants to get serious about cutting fat.

I lost an insane amount of body fat with Instant Knockout in just 3 months – I went from 17% body fat to below 8% – Now before you go shaking your head about these results, please note that I was training my ass off and running a serious Intermittent Fasting diet (taking in around 1800 calories a day).

Now if you’ve ever done intermittent fasting, especially at the deficit I was doing you know how unbearable those non-eating windows can be. Instant Knockout was just the medicine I needed to cope with the fatigue.

The caffeine really helped me keeping my energy levels up and the glucomannan filled me up enough to keep me satisfied until the next eating window.

If you’re getting really serious about cutting, and want results fast, I suggest you go for Instant Knockout. Due to the caffeine keeping my energy levels up I was able to maintain pretty much all of my muscle mass.

I naturally struggle to have a six-pack, and at most get a soft four-pack – but combining my exercising and dieting with Instant Knockout I got absolutely shredded. Even sitting down, my abs still shoot out of my stomach. It feels absolutely awesome.

Just take a look at my results:

Instant Knockout Review Conclusion

In conclusion, this fat burner is the best we’ve tried, and the best you can get.

The ingredients are well-balanced and incredible effective. You can expect to burn a lot of fat through a steady thermogenic profile of green tea, green coffee bean and cayenne pepper. It raises energy levels through use of 300mg of caffeine and even raises metabolic rates to burn more fat.

The glucomannan helps with reducing cravings by swelling up in the stomach and increasing fullness. The chlorogenic acid in the green coffee also helps by converting glycogen into glucose and helping the body need less carbs.

Bottom Line: This fat burner kicks ass, and I’m glad the manufacturer decided to release it to the public instead of keeping it in the MMA. If you train hard and diet right, you’ll look incredible within a few months of using it.

Top 5 Questions I get asked the most about Instant Knockout:

How long does it take to work?

Good question.

In my experience it takes around 3 months if you want to maintain your weight but get shredded.

You’ll feel the effects almost immediately, but that’s the caffeine, you’ll start slimming down after around a month of good training and diet.

The second month you’ll start toning up, and that’s what gives you the motivation to work even harder.

Then the third month is amazing. You start to see your ideal physique coming out, and it’s amazing.

If you’re naturally a skinny-fat dude like me, this will take your physique to the next level. I seriously recommend it.

Does it ship to my country?

As far as I know these guys ship worldwide, even APOs – I’m pretty sure it’s free as well depending on what deal you get.

Find out for sure on their website.

Did you personally experience any side effects?

I missed a serving once and had it at night to make up for it – the caffeine (obviously) kept me up for a few hours. It was pretty annoying.

But that’s the same with any fat burner. Don’t make that mistake.

I’m in the Army/National Service, and I get drug tested – Will this show up?


All the ingredients are completely natural. You’re not going to have a problem with this.

    Hi there,

    I’ve been using this for two weeks now and I’ve noticed a bit of difference already.

    Can you tell me what diet you were on to achieve those results?

    Thanks in advance,

      Hi Ed,

      I’m sorry it’s not working out – I had awesome results.

      What’s your diet looking like? If you’ve only been taking it a week, I suggest you give it more time.

      Let me know how it goes,


  5. Pete D.

    I am happy with my Instant Knockout.

    I took this for 3 months and it was great, but I was a little disappointed though. I thought the 3 box deal would have an extra box included, but for Canada they would only send 3.

    Any reason why this is? I’m probably going to order again for my next cut, is there a way to get the 4 for 3 deal?

    Anyway, good product, would recommend, nice review too,

      Hi Pete,

      Glad you’ve had some good results. I’ve just checked their website and it’s down to a ‘custom restriction’ so instead they’re doing “Buy 2 get 1 half Price”, no idea how you’d get around it I’m afraid, still cheaper than what I paid.

      Hope that helps.

      Hi Dwayne,

      That makes sense, the caffeine helps with power output. It should help you go harder on the sessions if you’re taking it just before a workout.

      Thanks for getting in touch,


  7. Alicia

    Hey! I need an extra kick to help me shed about 40lbs of fat for the millitary. Can women use this product to lose weight as well?

    1. Alpha Fat Burners (Post author)

      Hi Alicia,

      Yes they can.

      I’m pretty sure they must get this a lot considering their product is shaped like a fist! They’ve now got a page up to show people it’s women-friendly:

      Hope this helps.

      Thanks for getting in touch.

    So on your LMNITRIX MELT review you state:

    “250mg of Caffeine in one serving is a little much…
    Considering most fat burners contain that amount over many servings throughout the day, pushing it all into one pill is going to lead to an energy crash.”

    This product however contains 300mg per serving and you seem to be find with that.

    1. Alpha Fat Burners (Post author)

      Hi Yania,

      Good spot. Instant Knockout has 300mg of caffeine over 4 individual servings throughout the day. You’re only getting 75mg per serving – not 300mg.

      Whereas with LMNITRIX MELT you get 250mg in one serving, which is pretty high.

      Sorry for any confusion – and thanks for getting in touch!

    I am interested in trying this product, but I am extremely sensitive to caffeine. I can’t have it after 12pm lunchtime. So if I took 2 pills for breakfast and 2 pills for lunch – is that safe? Thats 150mg of caffeine in one dose…. I noticed that Phen Q is almost 150mg of caffeine per pill, so I guess it is all the same….

    1. Alpha Fat Burners (Post author)

      Hi Miranda,

      We’ve actually written a comparison of article of Instant Knockout and PhenQ – you check it all out here:

      Instant Knockout is recommended to be taken over 4 Servings a day. That works out at 75mg of caffeine per serving.

      Whereas PhenQ is only 2 servings a day which works out at 150mg – double the amount.

      Hope this helps 🙂

    Wait how can you say furious cuts has too much caffeine when this one has even more?

    1. Alpha Fat Burners (Post author)

      Hey Anon,

      Great question. Instant Knockout has that heavy 300mg spread out over 4 individual servings throughout the day.

      The label represents a daily serving, not an individual one.

      Thanks for getting in touch!
