The professional choice

For the past decade, the Instant Knockout team have been considered trusted experts and advisors in weight loss management to legendary MMA coaches and fighters. They come to us when the scales aren’t tipping like they should with the date of the big fight fast approaching.

Why us? Because there’s no-one better placed in the science of cutting weight. They turn to us because the unique Instant Knockout system is effective, safe, legal and tested. Nowhere is the big news: You don’t need to be a professional athlete to enjoy all the benefits of the Instant Knockout system.

Discover why he tells his fighters to use Instant Knockout when they need to lose weight quickly but safely.

With over 20 years experience of training championship fighters, Greg Jackson is the best of the best for coaching MMA. He knows exactly what's required to win in the octagon – and how important it is for a fighter to make weight.

Losing the pounds is easy, but burning fat is a different matter – it's a much harder job. Not knowing the difference may get you to your goal weight, but lose you the bout.

The more muscle mass you maintain the better – ripped and ready beats starved and sluggish every time. Greg knows this, and believes Instant Knockout is the ultimate tool for cutting down and kicking ass.

Greg’s achievements include:

  • 3 x MMA coach of the year
  • 2 x MMM gym of the year

Notable students include:

  • Georges St. Pierre - Former Welterweight Champion
  • Holly Holm - Former Women's Bantamweight Champion
  • Diego Sanchez - The Ultimate Fighter Season 1 Middleweight Winner

Impressed with its natural ingredients and effective results, Instant Knockout is the only weight-loss program recommended by legendary MMA coach Greg Jackson.

Instant Knockout Complete and Cut products pouch and box

The weight-loss system backed by science

The last 12 weeks before a big fight are crucial in any fighter's preparation. They'll often need to cut tens of pounds to weight, without losing any muscle, speed or strength. How is this even possible? They know they can trust the science behind the Instant Knockout System.

To achieve significant shredding - without stripping muscle - it is necessary to experience:

  • Appetite Suppression
  • Calorie Control
  • Thermogenic boost
  • Nutritional Balance

Previously, this process was either complex, expensive or ineffective. First generation fat burners were weak. Calorie control meant missing outon essential nutrients. Tailored, balanced meal plans cost hundreds of dollars per month. It meant fast, safe and long-lasting weight loss was out of reach for 99% of the population.

Until Instant Knockout came along with a game-changer in weight-loss management.

Because the Instant Knockout system provides these benefits - and more - delivered direct to your door. And all at a price less than the cost ofyour daily cup of coffee.

Fighters choosing the Instant Knockout system receive a round-the-clock fat-fighting formula that helps you cut weight, even while you sleep. And now you have an opportunity to join them.

Scientifically backed,
100% natural SOURCES

All Instant Knockout products are developed by experts to give you key ingredients and nutrients to keep you fighting fit. They've spent time researching the most cutting edge formulas in nutritional science so you don’t have to.

Both Instant Knockout Cut and Instant Knockout Complete have unique formulas designed to work together (or alone) to really make a difference. They’re both all natural, contain absolutely no proprietary blends and only contain ingredients backed by science.

Designed to be combined

The Instant Knockout System combines two world-class fat-fighting products: Instant Knockout Cut and Instant Knockout Complete.

Use either product in isolation for results you can see and feel within weeks. 100,000s of thousands of men attest to the powerful results they experience when using Cut. But when Cut is combined with Complete, the results are amplified and leveraged. Here’s how:

Instant Knockout Cut Bottle

Cut enjoys legendary status in the combat sports arena. Built upon a decade of innovation, this fat-fighting supplement utilises 9 PROVEN fat-burning ingredients, all in one handy capsule.

Each bottle contains a massive 120 capsules, providing you with an entire month of fat-burning, appetite-suppressing and energy-boosting benefits

And we’ve never rested on our laurels. Instant Knockout Cut is now on its 2nd iteration - each version building upon the last to offer even greater benefits and proven advantages.

  • Appetite Suppression
  • Thermogenic boost
Instant Knockout Cut Bottle

Complete is our latest innovation, and is designed to work alongside Cut. Based upon the latest in food science, Complete is a calorie-controlled meal replacement shake designed to keep you satisfied during a period of controlled calorie deficit.

When strength and muscle retention is key, Complete provides the reassurance of complete nutritional balance. It’s why MMA coaches choose it for their fighters. By fueling them with a Complete shake, they can be confident that cutting the calories doesn’t mean losing the nutritional advantage.

Even better, Complete is super-convenient. Just add water or milk, shake and drink. Each tasty vanilla-flavored mouthful provides a range of vitamins and minerals, making you feel fuller for longer, and all at just 400 calories per serving

  • Calorie Control
  • Nutritional Balance

Why do professional athletes favour the Instant Knockout system?

IKO Cut not only helps in the short-term run-up to the weigh-in, the system has been designed to also help you achieve your long-term goals.

A cycle of gaining weight between fights, only to have to lose it time-after-time, puts a strain on the body. Fighters look for long-term change in their body composition. It ensures they can always perform at the top of their game - both during a fight and at every training session throughout the year.

The IKO system helps to deliver that change. It’s not a fad diet that is unattainable over the long-term. It gets to work fast… But can be used consistently to help you maintain your ideal physique.

MMA Hall of Famer and Ultimate Fighter tournament winner Diego Sanchez puts his trust in Instant Knockout when he needs to lose weight fast.

MMA legend, Diego Sanchez cut from 190lbs to 145lbs using Instant Knockout. After recovering from his collarbone injury – the 'Original Ultimate Fighter' revamped his career by shredding down to the Featherweight Divison. But he couldn't do it alone.

To support his ambitious goal, Diego started using Instant Knockout. Exploiting the fat burner's thermogenic and appetite suppressing qualities, 'The Dream' increased his caloric deficit and managed to lose the first 25lbs in just 5 weeks.

Some of Diegos notable achievements include:

  • 2010 - Fight of the Night (vs. Paulo Thiago)
  • 2011 - Fight of the Night (vs. Martin Kampmann)
  • 2012 - Fight of the Night (vs. Jake Ellenberger)
  • 2013 - Fight of the Year (vs. Gilbert Melendez)
  • 2013 - Fight of the Night (vs. Gilbert Melendez)

Within the first week I noticed that I had much greater energy levels, and I was now reaching PBs in the gym. The appetite suppressing effects of Instant Knockout were able to stop me from snacking on chocolate bars and crisps in between meals.”
