What is Instant Knockout Complete?

Instant Knockout Complete is a high-protein meal replacement shake that is suitable for vegans. It is designed to replace at least one of your meals each day. Helping you to stay within a calorie deficit (for weight loss), maintain weight, or it can even be used to gain weight in an efficient and healthy way.

Instant Knockout has been designed to dovetail perfectly with Instant Knockout’s other brand Instant Knockout Cut. This is a fat-burning supplement. The idea is that you create a calorie deficit by raising your metabolism (using Instant Knockout Cut) and controlling your calories with the meal replacement shake.

Instant Knockout Complete is high in protein as well as fibre, making it ideal for weight loss. It can keep you feeling fuller for longer and reducing the likelihood of you feeling hungry between meals and snacking.

What Sports/Activities is Instant Knockout Complete best suited to?

Instant Knockout was designed to be used in fighting sports such as boxing, MMA, and wrestling. But there are many other sports that it would suit. Field sports such as football, rugby, American football, and medium distance track events would be perfect.

Any sport or event where you need to make a certain weight would also be improved. Bodybuilding is an obvious choice, due to the need for very low calories towards the end of a cut. The only sports or activities it may not suit would be endurance running.

This is due to the low carbohydrate content (crucial for weight loss). But you could easily combine the shake with a high-carb food, so it is still possible to benefit from Instant Knockout Complete even if you are performing ultra-endurance sports.

In fact, due to it being easy to digest and quick to make, it would be a perfect choice for peri-workout nutrition during an ultra-marathon or triathlon.

Instant Knockout Complete ingredients

Instant Knockout Complete ingredientsUnlike some meal replacement shakes, Instant Knockout Complete has kept their ingredients list quite short. Trusting in the efficiency and quality of their ingredients. There are seven main ingredients that we are going to take a look at now.

Plant Based Protein

Instant Knockout Complete has thoughtfully used plant based protein, making it product suitable for omnivores, vegetarians, and vegans. The two plant based protein sources they have used are pea and soya.

Unlike whey protein, plant based protein is actually better when there are different sources being used. This is because plant based protein doesn’t often have a complete protein profile of amino acids. So, combining two different protein sources can help to rectify this issue.

Pea protein is very popular in plant based protein supplementation because it is very efficient provides a high protein to calorie ratio.

Golden Flax Seed

There are two benefits to adding golden flax seed to a meal replacement shake. Not only is golden flax seed a superb source of omega 3 fatty acids, but it is also a great source of fibre.

There are many benefits to increasing the amount of fibre in your diet, but the main benefit for people looking to lose weight is that high-fibre foods are highly satiating. They make you feel fuller for longer.

Studies have shown that increasing fibre intake, even when not combined with calorie restriction, can lead to significant weight loss in overweight or obese adults.

MCT Oils

MCT stands for medium-chain triglycerides, they are an incredibly healthy form of dietary fat that have been shown to slightly boost your metabolic rate. But there are many other benefits to MCTs.

They have been shown to reduce lactate build-up in athletes, which could lead to an improvement in exercise performance. There are also health benefits, with MCT oils being associated with a reduced risk of heart disease or other metabolic diseases such as diabetes.

The MCT oils in Instant Knockout Complete come from coconut oil, which is very popular due to its health benefits.

Oat Flour

Instant Knockout Complete gets a lot of its carbohydrates from oat flour, which is a great choice for weight management. This is due to its relatively low GI score (37) and its high fibre content.

It is also easy to digest, and it provides controlled energy release, helping you to avoid those awful sugar crashes that can seriously affect hunger between meals.

Organic Brown Rice

While a lot of the plant based protein comes from soya and pea protein, a healthy dose of protein comes from organic brown rice concentrate. This helps with the amino acid profile of the protein, as it is an excellent source of leucine, isoleucine, and valine.

Chia Seed

The final ingredient on this list is chia seeds. As with golden flax seed, chia seed is a great source of both omega 3 fatty acids and fibre. It is also a source of protein.

Chia seeds fit really well into this product and offer a number of health benefits. They are very popular in vegan diets due to the protein, fibre, and healthy fats, and they are also popular due to their calcium content.

Instant Knockout Complete Review

Who is Instant Knockout Complete suitable for?

The most obvious audience for Instant Knockout Complete is vegans. This is due to it being fully plant based, while providing nutrients that many vegans can sometimes struggle to fit into their diet (omega 3 fatty acids, calcium, leucine).

But non-vegans can also benefit from taking Instant Knockout Complete. It is perfect for anyone who struggles to hit their calorie targets. Whether that is because you are going over your calories or going under.

It’s also perfect for anyone who struggles to hit their protein targets. Studies consistently show that people struggle to get enough protein at breakfast or lunch, with most people who follow Western diets consuming the majority of protein at dinner.

It is best practice to consume your protein steadily throughout the day, and many people would benefit from higher protein breakfasts and lunches. Instant Knockout Complete is perfect in this scenario, making it a lot easier to hit your targets.

Do the ingredients in Instant Knockout Complete work?

The ingredients in Instant Knockout Complete certainly work. There aren’t any ingredients present that are even debatable. Organic brown rice, soya protein, and pea protein are all well-known sources of high quality protein.

Chia seeds, golden flax seeds, and MCT oils, are also well-established as healthy and effective. Oat flour is very popular as a healthy carbohydrate source.

What’s great about Instant Knockout Complete is that it focuses on high-quality, natural ingredients. That means that you can have confidence that all of the ingredients work.

Instant Knockout Complete Meal Nutrition Facts

Instant Knockout Complete side effects

Due to the use of natural ingredients that are often found in healthy diets, there is a distinct lack of any side effects from taking them. New users may notice some digestive issues due to the high fibre content and the fact that it is a liquid meal.

This is not necessarily a side effect, as high fibre meals and increased hydration will provide positive benefits. But it may take a day or two to get used to being more regular.

Where to buy Instant Knockout Complete

Instant Knockout Complete is only available from the Instant Knockout website. This is done to ensure that the quality of the product remains incredibly high. Instant Knockout Complete offers free delivery to US and UK customers, and sells packages of 1, 2, or 3 pouches (each pouch containing 2 week’s supply).

Alternative to Instant Knockout Complete

There are a few alternatives to Instant Knockout Complete. Huel and PhenQ both offer high-quality meal replacement shakes. However, PhenQ contains whey protein, so is not suitable for vegans.

Huel as an alternative is slightly cheaper per serving but contains only 29 grams of protein per serving compared to the 35 grams that Instant Knockout Complete contains.

Instant Knockout Complete: My verdict

Instant Knockout Complete is a stellar meal replacement shake and is ideal for vegetarians or vegans. I really like the high-quality ingredients, and the protein to calorie ratio is superb.

The lack of choice when it comes to flavours was a concern, but I actually really enjoyed the subtle vanilla taste. Matched with the excellent consistency it made for a delicious yet not overpowering meal.

If you are looking to lose weight, maintain weight, or even build muscle, then Instant Knockout Complete is a superb product to add to your diet. High in protein, relatively low in carbs, full of healthy fats and fibre. This meal replacement shake will make dieting easier and save you both time and money in the long term.
