Instant Knockout Review: Detailed Review and Analysis

Instant Knockout Review (leadspring 4)

During my ten-year-old career as a fitness coach, I’ve worked with different types of clients, from bodybuilders to people looking to lose weight.

Recently, I’ve also started working with an MMA fighter who wanted to know what my stance on Instant Knockout is and if he should take it.

I did hours of research on Instant Knockout ingredients, checked countless Instant Knockout reviews, and consulted with a dietitian friend. Here’s everything I learned about this weight loss product.

What is Instant Knockout

Instant Knockout is a fat-burning supplement developed for professional athletes, such as boxers and MMA fighters, to help them burn fat and lose weight safely and quickly.

This product has a mix of ingredients that range from plant extracts to vitamins and minerals to caffeine. The ingredients can:

  • Trigger body burn
  • Increase energy levels
  • Boost the metabolism

Each fist-shaped bottle contains 120 capsules, which the official Instant Knockout website claims have a revolutionary formula that allows users to burn fat without experiencing jitters.

Some of the athletes who use Instant Knockout are MMA fighter Diego Sanchez and MMA coach Greg Jackson. Sanchez says he cut down to 145lbs and lost 25lbs in five weeks.

About The Brand

Instant Knockout fat burner is manufactured by Roar Ambition — a sports performance supplements company. Roar Ambition originates from the UK, and it’s been operating since 2014.

Roar Ambition refuses to sell its products through third parties, which means you won’t find its products in shops. You can order the product straight from their website.

They do this to keep the cost down because their ingredients are expensive, the fat burner costs more to produce.

They use only natural ingredients for their fat burners. Moreover, they only have a few products, which allows them to keep a close eye on each product they produce and revise the fat burner formula to keep it current.

Roar Ambition first created Instant Knockout for professional athletes, and only after they reported positive reviews, the product was released to the public.

The brand has made a name in the health supplement industry over the years, and the products they manufacture seem to be favored in the market.

Is Instant Knockout one of their best products? More on that below.

How Does Instant Knockout Work

Instant Knockout works on the principle of negative energy balance. The fat burner uses natural ingredients that attack the fat stores and aid your losing weight process.

Boosts the Metabolism

Instant Knockout is a metabolism booster, especially thermogenic metabolism, which increases energy expenditure by burning more calories from food and stored fat.

Metabolism functions by converting food into energy, and a higher metabolic rate means energy obtained from food burns faster. This converts fat stores into energy you can use.

To sum up: Instant Knockout makes your body start fat burning because the energy needs exceed the caloric intake.

Appetite Suppressant

Every dieter knows how it feels to have food cravings.

If you have a snack during your diet, it’ll stop the fat-burning process and increase instead of lower the fat storage.

This product claims to reduce food cravings and suppresses the appetite, which means no more hunger pangs.

It’s simple math. The recommended caloric intake a day is 2,000 calories. If you eat less, you’ll lose weight, but if you eat more, you’ll gain weight. Because Instant Knockout is an appetite suppressant, it can suppress hunger cravings.

It’s beneficial for athletes in fasting periods and when exercising in the morning before eating breakfast.

Boosts Energy Levels

Having fewer calories means having less energy, which can be an issue when you want to work out.

This is where the fat burner claims it can help. It contains stimulants that give your body energy, even during intense workouts, such as a cardio workout or weight training.

Because your energy levels will be higher, you won’t feel tired during and after the workout.

Ingredients in Instant Knockout

The creators claim they use only natural ingredients in Instant Knockout, which allows it to achieve all the above-mentioned benefits without the unnecessary fillers. The fat burner formula has been changed over time, so now Instant Knockout Cut uses ten ingredients.

I’ll go into depth on all ten, starting with the three most important ones.

Green Tea Extract

The fat burner has a high dose of green tea extract, which has been proven to affect the metabolism due to polyphenols and caffeine. These help the body use the stubborn fat reserves, which results in loss of body weight.

Another reason why green tea is successful in aiding weight loss is that it contains antioxidants known as catechins. Catechins reduce the body’s suppression of a hormone called norepinephrine, which is a fat-burning hormone. So, the more norepinephrine you have, the more fat you’ll burn.

Green tea extract effects have been the object of a systematic review. Here’s what scientific evidence says:

  • An average cup of green tea burns 5.7g of fat
  • Green tea has L-Theanine, which is an amino acid that can improve attention span

One study done on mice with high-fat diets concluded that mice who used green tea had a 27.1 mass body reduction, but the mice who didn’t take green tea extract didn’t achieve the same results.

Green Coffee Bean

A lot of nutrition is lost during the coffee roasting process. This is why green coffee is beneficial and green — it’s coffee beans that haven’t been roasted.

Green coffee beans also have a chlorogenic acid, which helps lower the levels of glucose in the liver. Because the body uses glucose for energy, when its levels are lowered, the body has to use fat stores to give you the energy you need.

The studies also show green coffee bean is beneficial/

One 12 weeks long study found that participants who took instant coffee that contained chlorogenic acid lost 5.4kg.

Another study concluded that green coffee beans help with burning fat and improving heart health.

Cayenne Pepper

Another ingredient that aids the weight loss process and weight management is the cayenne pepper. Cayenne pepper is the component that gives hot chili its heat.

It can help users lose body fat because it contains capsaicin. When the body absorbs capsaicin, the body temperature rises, and the body has to cool off. This means the body uses more energy than it normally does, which results in fat loss.

Studies also show that capsaicin not only burns energy but helps suppress appetite and boost insulin sensitivity.

One serving of Instant Knockout Cut has 100mg of cayenne pepper.


Glucomannan is a popular ingredient in other fat burners too.

It’s a dietary fiber and has the ability to suppress appetite because it makes you feel full for long periods because the body takes a long time to digest it.

It’s made from the root of the konjac plant. Once you consume it, it swells in your stomach, which means you feel the need to snack during the day.

Scientific research shows that the average weight loss when using glucomannan is 5.5.lbs over eight weeks.

Apart from weight loss, glucomannan also helps with:

  • Constipation
  • Improves blood sugar
  • Slows absorption of cholesterol

A daily dose of Instant Knockout Cut has 1800mg of glucomannan.

Vitamin B6

Vitamin B6 helps bring all the ingredients together.

Its benefits include:

  • Boosts the metabolism
  • Improves mood
  • Minimizes risk of heart disease
  • Enhances brain functions

Vitamin B12

Vitamin B12 helps:

  • Break down the fatty acids and boosts fat oxidation
  • Converts food into energy the body can use
  • Maximizes protein synthesis

As B6, B12 can also help improve the mood and fight depression by boosting serotonin levels.

Vitamin D3

This vitamin aids testosterone production in men. It can also reduce blood pressure and support heart health.

Some studies have shown that high amounts of Vitamin D3 reduce the chances of bone fractures, which is especially significant for MMA fighters.

This shows Roar Ambition has thought of everything.


Piperine is a black pepper compound. Studies show that it can help with digestion, boost metabolism, and suppress the formation of new fat cells.

Apart from fat-reducing effects, piperine also has anti-inflammatory properties.


The Instant Knockout formula also has L-Theanine, which is beneficial when used together with caffeine.

When caffeine causes a crash, L-Theanine prevents the loss of energy.

Another major L-Theanine benefit is that it prevents jitters during a workout and helps come down from the workout high.

Caffeine Anhydrous

Similarly to regular caffeine, caffeine anhydrous boosts energy. It does this by releasing neurotransmitters, such as dopamine, which makes you feel more awake.

This is beneficial if you’re on a low-calorie diet. Caffeine intake will give you the kick you need to get through the day and the exercise regimen. Apart from increasing energy levels, caffeine speeds up the metabolism and helps with focus and concentration.

How to Take Instant Knockout Cut

For optimum weight loss results, the packaging says you should take one capsule four times a day with meals.

This is good for weight loss, as the body will always have nutrients that increase fat oxidation, and the fat loss process will be constant.

It’s not so great having to think about the dosages throughout the day, especially when you’re busy.

One thing you can do is stack Instant Knockout daily doses in one place and set alarms to remind you it’s time to take the next dose until you get used to taking Instant Knockout regularly.

Note: Avoid taking Instant Knockout Cut close to bedtime because Instant Knockout contains a high amount of caffeine, and it can interfere with sleeping.

In fact, the label itself says that you shouldn’t take this weight loss supplement five hours before sleeping.

Instant Knockout Cut Benefits

I’ve already talked about how Instant Knockout boosts the metabolism, suppresses the appetite, and increases energy. Here’re some other benefits I’ve found while reading Instant Knockout Cut reviews:

  • Improves mood and enhances brain functions

    While other fat burners mostly focus on fat burning, Instant Knockout uses mood and brain enhancers to make you stick to your weight-reduction plan. A good mood positively impacts weight loss, and there’s a higher chance of sticking to healthy eating habits.

  • Helps you keep muscle mass

    Instant Knockout Cut uses Vitamin B6, which helps the body to absorb amino acids that help build muscle. Also, caffeine helps give you more energy when working out, which also results in muscle growth.

Instant Knockout Possible Side Effects

As a rule of thumb, you should consult with a doctor before taking fat burners, especially if you have medical conditions or allergies.

Note: if you’re pregnant or breastfeeding, you shouldn't take Instant Knockout.

One thing to be aware of is that Instant Knockout Cut has 300mg of caffeine per daily serving. Considering that up to 400mg of caffeine a day is a dose for most healthy adults, it means that Instant Knockout caffeine amount is high.

If you’re taking caffeine from other sources, you may want to lower your intake. It's a good idea also not to take fat burners before bedtime to avoid insomnia.

Where to Buy Instant Knockout

You can purchase Instant Knockout on the official website. There, you can also read Instant Knockout Cut reviews.

By buying fat burners on the official website, you can also take advantage of their discount if you buy more than one bottle at a time.

What’s more, now you can buy Instant Knockout vegan, as the new formula is vegan and vegetarian friendly, so everyone can get those fat body burns.

How Much Does It Cost

Instant Knockout comes at a premium price because of its high-quality ingredients.

Instant Knockout prices are:

  • One bottle for $59
  • Two bottles for $118
  • Three bottles for $185

One bottle is enough for one month of use, while three bottles will last you four months.

When you buy two or more bottles, you get free UK and USA delivery, and if you choose a 90 days pack, you get one additional bottle for free.

Yes, the cost is higher compared to other products of this kind, but Roar Ambition offers a 90-day money-back guarantee, so even if you don’t end up losing weight, you’ll get your money back.

Should You Buy Instant Knockout?

I hope you found this Instant Knockout review helpful.

I’ve talked about the company behind the product, the ingredients, side effects, and the recommended dosage.

Overall, it’s an effective fat burner that can help you burn more calories and get rid of the fat stores that have been plaguing you for ages.

But, the Instant Knockout fat burner won’t do miracles on its own. You’ll need to stick to a healthy diet and a consistent workout regimen. Also, if you’re caffeine sensitive, the high caffeine amount could be an issue for you.
