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 when the date of the big fight is fast approaching.

Why us? Because there’s no-one better placed in the science of cutting weight. They know that when they turn to Instant Knockout, their fighter loses weight fast, using a product that is legal, safe and effective. It’s why legendary MMA coach Greg Jackson recommends Instant Knockout.

Here is the big news: You no longer need to be a professional athlete to enjoy all the benefits of Instant Knockout. If you need to quickly lose weight for your own big occasion, we’re in your corner.

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 by its natural ingredients and speedy results, Instant Knockout Cut is the only product legendary MMA coach Greg Jackson recommends to his fighters to get ripped and lean.

Instant Knockout Couples Abs

Imagine what you would look like if you could finally burn your fat...*

Hot, right? Confident, fit, healthy and buff. Your clothes would hug every part of your toned body. No longer would your hard work in the gym be hidden under that stubborn layer of unsightly fat.*

  • Firm, sculptured shoulders – check*
  • Ripped, defined arms – check*
  • Awesome, flawless 'six pack' – check*
  • Shredded, carved legs – check*

When you finally reach your fat burning goals, you can truly enjoy the fruits of your labor. Playing sports, posing along the beach, impressing in the bedroom... in fact you could even be stripping down and showing off, whenever you have the chance.*

There's something extremely confidence boosting about defined muscles. It's often the case that you don't even need to be that big or muscular to look great when you're defined. It makes your hard work in the gym look much more visible.

And THAT, after all, is the whole point.

Instant Knockout bottle and box

"OK, I like the sound of that... but what’s the solution?"

Only the Instant Knockout Cut formula delivers the perfect combo of ultra-powerful fat burning heavyweights in every capsule. Exhaustively researched and scientifically formulated, it gets your body into fat-burning mode faster and easier than ever before.

If you take Instant Knockout with a healthy diet and regular exercise, chances are you won't need anything else. And once you see how effectively all three work together... you may not WANT anything else.

We presume that you haven't been impressed with the previous fat burners you have bought, otherwise you wouldn't be here.

Unfortunately, many of them are designed with just the price in mind. Many manufacturers will keep THEIR costs as low as possible, yet still charge YOU a small fortune for a low-quality, poorly-researched product, that never stood a chance of being effective.

Even if they choose the correct ingredients, which many companies simply don't spend enough time researching, they are not in large enough quantities to make a real impact on your fat burning efforts. A sheep in wolf's clothing. All mouth and no trousers.

We designed Instant Knockout however, with power in mind. No compromises, no cost cutting, no inferior ingredients. Imagine your average fat burner as a 2 liter saloon car. Instant Knockout is like a 5 liter, twin turbo, supercharged, six speed, carbon fiber supercar. There really is no comparison.

It's not just for those who want to look like a professional fighter however, Instant Knockout helps anyone who wants help to lose their unsightly fat, stress free and without taking harsh, side-effect riddled chemicals.

PLEASE NOTE: Do not be tempted to take more Instant Knockout than the recommended dose.

The core ingredients

Green Tea

Green Tea Extract

Speeds up your metabolism and boost fat oxidation.

This powerhouse nutrient fights fat from different angles, making it an essential Instant Knockout nutrient.

Studies show that green tea can elevate your metabolic rate and calorie burn via a process of thermogenesis, helping you to tap into stored fat[1]. It ramps up fat burning by over 15% and gives you a much needed kick of energy – even when you’re in a calorie deficit.

1. Hursel, R et al. The effects of green tea on weight loss and weight maintenance: a meta-analysis. Int J Obes. 2009; 33(9): 956-61

Cayenne Pepper

Cayenne Pepper Seeds

Speeds up your metabolism and boost fat oxidation.

This nutrient-packed spice contains capsaicin – a bioactive compound known for its fat burning ability.

Much like green tea, capsaicin is a potent thermogenic. It has also been linked to reduced appetite levels.

One way to kick start a calorie deficit is to consume less calories. The capsaicin in Cayenne Pepper seeds has been shown to have ‘reduced the desire to eat’ in two studies [2].

2. Yoshioka M, St-Pierre S, Drapeau V, Dionne I, Doucet E, Suzuki M, Tremblay A. Effects of red pepper on appetite and energy intake. Br J Nutr. 1999 Aug;82(2):115-23. PMID: 10743483.



Suppresses your appetite to reduces cravings.

Glucomannan is a dietary fiber that reduces appetite and food cravings by helping you feel fuller for longer.

As a soluble fiber with a long-chain, complex carbohydrate structure, it boosts weight loss by helping you avoid the triggers of over-eating and excessive snacking.

Current research suggests that glucomannan could be the key to weight-related, metabolic health issues in the US[3].

Age: 21, Goals: Shred fat after injury

“I used Instant Knockout for 8 weeks in order to try and shred the last bits of fat before the summer holidays. 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.”

The Cornerstones of Weight Loss with Instant Knockout

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.
