Instant Knockout Complete

Pro fighters know that they not only have to cut weight to make the big weigh-in, they absolutely have to be in peak physical condition to stand a chance of winning. Quite simply, to perform at their best, their diet must provide them with everything they require - with zero corners cut. Which is why the professional athletes combine their daily serving of Instant Knockout Cut with Instant Knockout Complete.

Instant Knockout Complete is a calorie-controlled, nutritionally-complete meal replacement shake designed to give fighters everything they need to achieve their goals - all at just 400 calories per serving.

Why do pro fighters and coaches insist on using Instant Knockout Complete when aiming to get shredded? Because Complete gives your body what it needs to perform as it should:

  • Without immunity support, fighters risk missing out on vital sparring sessions
  • Lacking in protein means lacking in muscle-based punching power
  • An imbalance of macronutrients means an imbalance in recovery times
  • Miss out on vital vitamins and minerals and you miss out on fully optimised performance
  • And if you are too hungry to focus, you’ll never hit those PBs in the gym

Complete was designed to solve all those problems - and more! Instant Knockout Complete removes all the headaches surrounding staying fit, healthy and strong while cutting fat safely, effectively and permanently.

The complete weight loss system

Complete is a meal-replacement shake that fuels you throughout the day, making it easier to lose weight and feel great. Complete is high-protein, vitamin-enriched, nutritionally-balanced and calorie-controlled. Even better, it tastes great! And at just 400 calories per serving, it’s the simple way to control calories without the hunger pangs.

Unlike the protein shakes you’ve had previously, Complete is food. It’s called Complete as it gives your body everything it needs - including a feeling of being full and satisfied - all at just 400 calories per serving.

It means you can power through your day, and give your best at the gym, whilst maintaining a calorie deficit - the key to effective and sustaining weight loss.

It is quick (make and shake in 30 seconds), convenient (take it on the go) and provides ultimate peace of mind knowing that all your nutritional needs are accounted for.

Instant Knockout Complete

And every carefully considered calorie it does provide is what your body needs. Unlike the hollow calories that many ‘energy’ bars and sugary protein shakes provide - which provide little of the nutrients you require - our professional nutritionists ensure that every serving of Complete is packed with slow release energy to keep you going right to the finishing line.

Ditch the calories and pick up the protein

Users of Complete who swapped out just one of their daily meals for Complete reduced their daily calorie intake by an average of 550 calories. Replace two of your meals with Complete and see the results you desire even quicker.

Worried about losing muscle? No need, it’s all been considered. In fact, the pro coaches and fighters we worked with on Complete demanded it. It’s why each serving is packed with a massive 35g protein boost. Even better, when you use Complete you enjoy the reassurance that all your body’s nutritional requirements are catered for.

The Complete science

Complete is the result of a 5-year research project into providing the perfect meal replacement for those on a weight loss journey. It has been formulated, tested and refined at each stage by some of the world’s leading nutritionists in state-of-the-art labs. Such an investment is beyond the reach of the vast majority of supplement brands. It’s why Roar Ambition, the exclusive manufacturer of Instant Knockout, and one of the world’s leading supplement experts, were the only ones with the capacity to make the impossible happen.

The benefits you can enjoy when you switch to complete:

  • 35g of protein for muscle growth and repair
  • 35g of carbohydrate for energy
  • 13g of fibre for digestion and slow release energy
  • Benefit from Vitamin D whether you train indoor or out
  • Vitamin A to help your skin and immune system
  • Vitamin E helps strengthen your immune system
  • Healthy fats Omega 3 and 6
  • Chromium to elevate your mood

Powerhouse ingredients at the core of Complete

Instant Knockout Complete Plant Based Proteins

Plant based Protein

Protein is one of the most essential nutrients your body requires to function correctly. For those in sports, it’s vital to help regulate your muscle mass, repair muscle after a period of exertion and is also a source of energy.[1]

The main source of protein in Complete comes from pea and soy extract. These fantastic sources of vegan protein are plant based, all natural and suitable for everyone.



Instant Knockout Complete MCT


Vitamin B6, like other B vitamins, are used to turn your food into fuel. B6 also has the benefit of motivating you further to keep your weight management plan right on track.

Medium Chain Triglycerides (MCT) are useful dietary fats that contain a host of potential health benefits. Studies have shown that MCT’s can provide you with a short rise in your metabolic rate, meaning you could burn fat faster.[1]

Instant Knockout Complete Chia Seeds

Chia Seed

What would you do if you could find a plant-based nutrient that’s full of goodness, yet has little calories? You’d want to use it, right? Let us introduce you to the humble but powerful chia seeds.

We’ve included chia seeds in Instant Knockout Complete as they contain fiber, protein, healthy fats like omega 3, calcium and other nutrients.[1]



Male or Female. Young or Old. Instant Knockout was made for YOU

Instant Knockout Complete was initially developed at the request of our MMA training associates. But we fully appreciate that the fighters who use it don’t look like 99% of the population. So, you might think it only works for those guys. Think again.

Every scoop of protein-packed Instant Knockout Complete not only provides nutritional peace-of-mind, it also makes you feel fuller for longer - no matter if you’re a woman or a man, young or old. By reducing cravings for between-meal snacks, it can help you lose weight without the heartache. And because each scoop is perfectly portion controlled, it makes tracking calories simple. Whoever you are, whatever your weight-loss goals, Instant Knockout Complete can help you achieve them faster. 

The Complete answer to sustainable weight loss

Alongside generous servings of plant-based protein, our R&D team have also ensured that every serving of Complete gives you all you require to lose weight and keep it off. Did you know that some fats are not only good for you, but they are essential? MCTs (Medium Chain Triglycerides) are fatty acids that can promote weight loss and switch off cravings when your body converts them into ketones. Complete uses the highest-quality MCT oils found in nature: the coconut.

And we have also considered how you will fuel your day (and workout) when you’re cutting calories. Unlike the crash and burn associated with many meal replacements, Complete is powered by the carbs provided by oat flour. This provides slow release energy over a prolonged period of time, so you feel ready to take on the day, no matter what time the hour.

Powered by nature

Why do fighters choose Complete? Clean ingredients. Pick up an off-the-shelf energy bar or shake and what do you see? An ingredient list packed with artificial sweeteners, lab-made colouring and animal derivatives.

Is that what you really want to put in your body? And store-bought meals are often packed with hidden sugar content. Complete is different. Our completely transparent ethos means you can be certain you only benefit from the power of nature.

Protein packed, naturally

Complete provides the perfect mix of two plant-based proteins - pea and soy. Both sources are high quality and easily digested, meaning you avoid the bloat associated with whey proteins.

And they are naturally lower in carbs and high in iron, which is perfect if you are counting the carbs. As a final bonus, they are an excellent source of BCAAs (branch-chain amino acids) which are proven to promote muscle growth and reduce muscle wasting.

We care what goes into your body; so should you

Complete was formulated by trained nutritionists and dieticians. Each ingredient was selected after studying a wealth of evidence on the science of sustainable weight loss.

Each pack of Complete is made in FDA registered facilities that adhere to cGMP guidelines.

And you can be reassured that Complete is safe and natural. Complete contains no chemical nasties and zero animal products.

Regulated, endored and verified by the FDA
