How does Instant Knockout Complete work? Should you buy the meal replacement formula? Keep reading to discover everything you need to know about Instant Knockout Complete and how it works.

What is Instant Knockout Complete?

Instant Knockout Complete is a meal replacement shake created by Instant Knockout.

Featuring a blend of vitamins, minerals, protein, and other nutrients, Instant Knockout Complete gives you a complete meal in each 100g serving. Just mix the powder with the beverage of your choice, then drink it daily to lose weight.

Instant Knockout is known for creating a popular thermogenic weight loss supplement called Instant Knockout Cut. With Complete, Instant Knockout built on the effectiveness of Cut to create an effective all-in-one weight loss formula for anyone who wants to lose weight.

Like Cut, Instant Knockout Complete is marketed to athletes and fighters. However, anyone can use the formula to lose weight.

How Does Instant Knockout Complete Work?

Instant Knockout Complete is a complete meal replacement shake with 400 calories per serving. Each serving of Instant Knockout Complete contains a strong dose of protein mixed with vitamins and other nutrients.


As Instant Knockout explains, their formula is called “Complete” because it gives your body everything it needs with just 400 calories per serving. It’s designed as a complete meal replacement powder – and it’s specially designed to leave you feeling full and satisfied.

While some weight loss shakes are designed to minimize calories and carbs, Instant Knockout Complete is designed to replicate the carbs and calories of a meal, helping you feel full and enjoy long-lasting energy throughout the day – all while getting just 400 calories per serving.

Each serving (2 scoops / 100g of powdered formula per serving) of Instant Knockout Complete contains 35g of protein, 35g of carbs, and 13g of fiber. The protein fuels muscle growth and repair, while the carbs and fiber help with digestion and energy.

Carbs provide a quick source of energy to your body, helping you stay energized all day long, while fiber helps with digestion and provides slow-release energy.

Instant Knockout Complete Features & Benefits

Instant Knockout Complete showcases all of the following features and benefits:

  • 35g of protein for muscle growth and repair
  • 35g of carbs for long-lasting energy
  • 13g of fiber for digestion and slow release energy
  • Vitamin D, vitamin A, and vitamin E from immunity, skin health, and antioxidant effects
  • Omega 3 and 6 fatty acids
  • Chromium to elevate your mood

Instant Knockout Complete Versus Other Weight Loss Shakes

You can find plenty of weight loss shakes available online today. What makes Instant Knockout Complete unique? Why pick this formula?

Typical weight loss shakes minimize calories and carbs and maximize protein. They’re designed to give you the maximum amount of protein while minimizing calories.

These shakes are fine if you’re following an ultra-low-calorie diet. However, these low-calorie, low-carb weight loss shakes aren’t ideal for active individuals.

Your body needs protein, carbs, fiber, vitamins, minerals, and nutrients to continue fueling itself. Without these ingredients, your body starts to eat its muscles, causing you to lose your hard-earned muscle mass.

Instant Knockout Complete is designed to fight muscle atrophy while giving you a satiating, high-powered, all-in-one meal replacement shake.

Instant Knockout Complete Ingredients

To understand how Instant Knockout Complete creates a complete meal replacement in each serving, it helps to understand which ingredients are inside the blend.

Instant Knockout Complete contains plant-based protein, for example, along with MCTs, oat flour, and golden flax seed, among other ingredients:

Plant-Based Protein: Instant Knockout Complete contains plant-based protein to help your body function correctly. The main sources of protein in Instant Knockout Complete include pea and soy protein. These are natural, vegan protein sources that are suitable for everyone. Each serving of Instant Knockout Complete contains 35g of protein, helping you repair and rebuild muscle faster.

Golden Flax Seed: Instant Knockout Complete contains golden flax seed, a small seed rich with omega-3 fatty acids and fiber. Getting more fiber in your diet is crucial for cholesterol, blood sugar, and weight management. The fiber in golden flax seed can also reduce your appetite, helping you consume fewer unnecessary calories while staying full for longer.

Oat Flour: Instant Knockout Complete uses oat flour to provide a natural, accessible source of carbohydrates. The carbohydrates in Instant Knockout Complete include the fibers, starches, and sugars within oat flour. Roar Nutrition specifically chose oat flour because of its low glycemic index. Oats have a GI of 37, for example, while white bread has a GI of 75. The lower glycemic index means you get more sustainable energy instead of an all-in-one surge. Oat flour is also rich in fiber.

MCT: Medium chain triglycerides (MCTs) are more popular than ever. MCTs are dietary fats that your body can quickly turn into energy. Your body processes MCTs more easily than longer chain triglycerides, which is way many people take MCT supplements in the morning for all-day energy. Like other MCT supplements, Instant Knockout Complete gets its MCT from the coconut. According to Roar Nutrition, the MCTs in Instant Knockout Complete can help with fat oxidation, fatty acid breakdown, energy, and metabolism. Overall, they help burn fat faster while giving you the all-day energy you crave.

Organic Brown Rice: Instant Knockout Complete contains organic brown rice, an all-natural source of protein. Popular in vegan protein powders, brown rice is rich with amino acids like valine, leucine, and isoleucine to help supply muscle tissues with energy, which is crucial for physical exercise.

Chia Seed: Chia seed is another popular vegan protein ingredient. Chia is rich with fiber, protein, healthy fats like omega-3, and calcium, among other nutrients. They also contain just 101 calories per 28g, which, which is very small.

How Does the Instant Knockout Weight Loss System Works?

Instant Knockout Complete is designed to have complementary effects with other Instant Knockout formulas. By taking Instant Knockout Complete and Instant Knockout Cut as a stack, for example, you can burn fat and suppress appetite while getting the full value of a daily meal.

The Instant Knockout weight loss system was developed as part of a partnership between Roar Nutrition and legendary MMA coach Greg Jackson. It’s based on the following four pillars:

Pillar #1: Thermogenic Boost: Thermogenesis is a fancy word for fat burning. Your body induces thermogenesis when you exercise, for example, or when it needs to burn fat for energy. Certain ingredients – like caffeine and cayenne pepper – have been shown to boost thermogenesis, encouraging your body to burn more fat. Thermogenesis is closely tied to metabolism. Many of the ingredients in Instant Knockout Cut, the complementary formula to Instant Knockout Complete, are designed to boost thermogenesis.

Pillar #2: Calorie Control: The only way to lose weight is to maintain a caloric deficit. You need to burn more calories than you consume every day. Instant Knockout Complete is designed to help with calorie control by suppressing appetite, naturally encouraging you to eat less. Instant Knockout Complete contains 35g of carbs, 35g of protein, and 13g of fiber, all of which should help you feel full for as long as possible. That means less snacking and fewer cheat meals, helping you reach your weight loss goals sooner.

Pillar #3: Nutritional Balance: Good nutritional balance is crucial for health and weight loss. Instant Knockout Complete provides you with a full range of vitamins and minerals – similar to a good multivitamin or leading meal replacement shake. Without good nutritional balance, your weight loss program will fail. Instant Knockout Complete aims to give your body the ingredients it needs to lose weight while preserving muscle mass.

Pillar #4: Appetite Suppression: Snacking and cheat meals can quickly ruin your diet. The ingredients in Instant Knockout Complete are designed to suppress appetite in various ways. These ingredients include fiber, carbs, and protein to help keep hunger cravings at bay, making it easier to stick to your weight loss goals.

Instant Knockout Cut delivers one of the four pillars of weight loss: the thermogenic boost.

Instant Knockout Complete, meanwhile, delivers another pillar of weight loss: the nutritional balance.

The final two pillars, calorie control and nutritional balance, are down to you. If you can stick to all four of these pillars, you can successfully lose weight.

Although Roar Nutrition discloses macronutrient values and vitamin levels upfront, the company does not appear to publish its full ingredients label, list of inactive ingredients, or dosages on the official Instant Knockout Complete website. We know the formula contains 35g of protein, for example, but we don’t know the dosage of MCTs, flax seed, chia seed, pea and soy protein, and other individual ingredients.

Scientific Evidence for Instant Knockout Complete

Instant Knockout claims Complete is backed by five years of research and development. The company claims to have formulated, tested, and refined the formula with help from some of the world’s leading nutritionists in a cutting edge lab.

Additionally, Roar Nutrition, the manufacturer of the Instant Knockout brand, cites dozens of studies on its official Instant Knockout Complete sales page to verify the supplement works as advertised. We’ll summarize that research and other studies below to explain how Instant Knockout Complete works.

However, not all of the studies indicate successful results. Roar Nutrition cites this study to justify its use of MCT, for example. In the study, researchers gave MCT supplements or LCT supplements to a group of 12 healthy, lean women. Total energy expenditure (TEE) did not change between the medium chain (MCT) and long chain triglycerides (LCT) groups, suggesting MCTs are no different than LCTs for boosting energy. Despite the lack of correlation, Roar Nutrition cites this study on its official Instant Knockout Complete sales page.

Fortunately, other studies do show MCTs can boost total energy expenditure. In this study, for example, researchers found greater fat oxidation in the MCT group after 14 days, suggesting MCT can increase fat oxidation and fat burning and help you lose weight.

It’s also true oat flour has a lower glycemic index than white bread and other carb-heavy foods. In this 2017 study, researchers also praised oat flour (A. sativa L.) for being rich with fiber, proteins, unsaturated fatty acids, vitamins, essential minerals, and antioxidants, among other nutrients.

Instant Knockout Complete contains two popular plant-based sources of protein, including pea and soy protein. To justify the use of these proteins, Roar Nutrition cites this study showing dietary protein is linked to muscle mass. Although the study did not specifically involve soy or pea protein, it did show that taking the right amount of protein per day (typically 1.2g/kg/d to 1.5g/kg/d) was associated with better muscle growth and development and less muscle wastage.

Overall, Instant Knockout Complete contains a blend of vitamins, minerals, and nutrients designed to support weight loss by giving you a complete meal replacement in each serving. By taking Instant Knockout Complete daily, you could complement a healthy diet and exercise routine, making it easier to lose weight.
