Instant Knockout Review

Instant Knockout is a combined fat burner and appetite suppressant consisting of a blend of ingredients in the form of a capsule supplement.

The product’s theme is centred around fighting, obvious from both the name and the bottle’s fist shaped design.

It’s not all marketing gimmick though, the recipe of ingredients is one that bares significance in the world of professional boxing and MMA (Mixed Martial Arts).

Professional fighters compete in weight categories, and as such must qualify for their competition weight category before getting into the ring.

In the off-season, they will have built as much muscle and mass as is sensible, before following a cut cycle to lose fat and make competition weight almost timed to the day of the weigh-in.

During the cutting cycle, they want to retain as much muscle and strength as possible so as not to waste the hard work they have put in.

There’s a science to it. Diet and training make up the lion’s share of the process, but it doesn’t hurt to have a supplement or two to help things a long.

When you want to burn the fat or get cut, the equation becomes a little trickier.

Now it’s time to cut more calories, change your workouts, include much more cardio and generally push the envelope. So that’s where Instant Knockout comes in.

How Do I Get the Best Out of Instant Knockout

There’s no two way about this; you have to work out and eat well. With a regular exercise program and quality diet, Instant Knockout’s positives will move the needle.

The extra fat you burn will carve your physique around your muscle tone.

It’s called a professional grade supplement for a reason.

IKO Benefits at a Glance

Using a blend of ingredients in each capsule, Instant Knockout is designed to help you:

  • Burn Fat – through increase in metabolism, thermogenesis and anti-oxidant behaviour
  • Boost Energy – through utilizing more fat for fuel, quality stimulants and improving blood sugar balances
  • Reduce Appetite – via a special inclusion which helps you feel comfortably full and able to reject the junk snacking

Instant Knockout aims to achieve all this using a carefully selected recipe of natural ingredients, all of which are included to compliment one another’s positive actions.

What Is Instant Knockout?

Instant Knockout is a blend of ingredients, put together to help you lose fat as efficiently as possible.

The product has several professional endorsements including that of Diego Sanchez and John Dodson III (MMA fighters).

Sanchez’s story is an interesting one. He used Instant Knockout as a tool to come back from post injury weight of 190 lbs to competition fighting weight of 145 lbs.

Training and Diet

Training and diet are obviously key to any weight loss plan, especially one that involves so much strength and muscle retention.

However, there are several ingredients that help burn additional calories, and others which suppress appetite between meals so that you don’t snack on junk.

Instant Knockout contains the supplement industry’s most proven fat loss ingredients.

You only have to do a little research in scientific journals and sports medicine databases to see that.

Instant Knockout Fat Burner

How Does Instant Knockout Work?

Instant Knockout works in three main ways, according to Roar Ambition, the manufacturer.

  • Metabolism Boost – by increasing your body’s resting metabolic rate (RMR) and active metabolic rate (AMR), more calories are burned over the course of a day.
  • Reduces Hunger Cravings – quality appetite suppressants are the a great way to lose fat because they help you to resist eating as much in the first place. Fat burning is great, but not taking on the calories to begin with is even better.
  • Fuels Energy Levels – keeping going during a weight loss drive is one of the more difficult aspects. It helps to have some energy boosters in the mix to prevent you from feeling washed out and weak.

Of course, the way it exerts these effects is through the ingredients that make up its formula. We’ll highlight those next.

Instant Knockout Ingredients

The following ingredients are per 4 capsules.

  • Green Tea Leaf Extract – 500mg
  • Cayenne Powder – 100mg
  • Glucomannan – 1800mg
  • Caffeine Anhydrous – 300mg
  • Green Coffee Bean Extract – 100mg
  • GTF Chromium – 100mcg
  • Zinc – 10mg
  • Black Pepper Extract – 10mg
  • Vitamin B6 – 5mg
  • Vitamin B12 – 10mcg

Whether you are excited by the above formula or not, it really is a collection of the industry’s most proven ingredients for losing fat, at effective doses too.

Here’s a bit more detail on some of the formula ingredients that you might be wondering about:

What’s in Instant Knockout

There are 3 core ingredients, around which the recipe for Instant Knockout has been based. Those core ingredients are:

  1. Green Tea Extract (500mg) – This powerful ingredient works on several fronts. It raises your metabolic rate whereby you use more fat for fuel to burn even more fat. It fuels a process called thermogenesis where your core temperature is raised so that your system cools it down, burning fat in the process. GTE also boosts your endurance, allowing you to workout for longer..and guess what – burn more fat.
  2. Cayenne Powder (100mg) – The heat from cayenne increases your core temperature and boosts thermogenesis, heightening the effect the GTE is already exerting. It also kicks your metabolism up a notch.
  3. Glucomannan (1800mg) – Extracted from the root of the Konjac plant, this soluble fibre is a very stable appetite suppressant. It absorbs liquid and swells to form a gel which simply makes you crave less snack foods in between your regular meals.
IKO formula ingredients

There are several more ingredients in Instant Knockout which we will cover briefly:

  • Caffeine Anhydrous (350mg): an effective stimulant at a healthy dose. Increases the effects of the core ingredients and provides you with a sustainable boost of energy.
  • Vitamin B6 (5mg): Used in so many processes in the body, it’s inclusion here is primarily for blood glucose management, food craving suppression and stimulation of thyroid gland. All adding up to further weight loss.
  • Vitamin B12 (10mcg): Helps break down the macronutrients (protein, fat and carbs), build and repair muscle fibre and again stimulate thyroid function.
  • Zinc (10mg): Helps you process macronutrients to be used as fuel for working out
  • GTF Chromium (100mcg): assists weight loss and muscle growth and helps regulate blood glucose
  • Black Pepper Extract (10mg): makes other ingredients more bio-available and therefore increases the effects of all the other ingredients in Instant Knockout
  • Green Coffee Extract (100mg): un-roasted raw coffee beans have high levels of Chlorogenic acid which slows the rate at which you absorb fat from food and it lowers levels of glucose in the liver.

Instant Knockout Suppresses Appetite

Glucomannan is a powerful appetite suppressant that forms a gel like mass in the stomach, sending “I’m full” signals to the brian and also preventing blood sugar spikes in the process.

Zinc will help people who exercise to retain optimal levels of testosterone for efficient muscle growth and energy.

When we sweat, zinc leaves our body and so it is necessary to replenish this vital micronutrient.

Cayenne Pepper has been found to increase thermogenic fat burning and light up your stores of Brown Adipose Tissue (aka brown fat).

Cayenne pepper is an incredible heat generating, fat burning system in our bodies that were are learning more and more about as time goes on.

Does Instant Knockout Have Side Effects?

People especially sensitive to stimulants might feel the caffeine and green tea, but the daily serving is split into 4 separate pills so you can just take one or two a day to begin with if this is a concern.

The ingredients are not associated with negative side effects, but if you are taking prescription medication, or have a medical condition, consult your doctor before taking Instant Knockout.

Pregnant women should avoid using this or any other supplement like it.

Other than these people in specific medical circumstances, the vast majority of people will experience no problems taking it.

Can women use Instant Knockout?

Absolutely! IKO works for both men and women and there is nothing in it that is gender specific.

How do I get the most out of Instant Knockout?

A: Supplements that contain caffeine and other stimulants work best when your body is unused to those ingredients. This is known as being caffeine “naive”. Basically, if you drink coffee every day then your body becomes tolerant to its effects. What you want is to be sensitive to its effects. So, for maximum efficacy, you should try not to consume any other source of caffeine while you are taking this supplement. After 3 to 4 months, you should “cycle off” (stop taking) it for 2 weeks before starting again. This resets your body’s sensitivity to caffeine and stimulants.

How quickly will I start to see results

Depending on your workout program and diet you will start to see visible results within one to two weeks. Remember that the only way to lose fat is to burn more calories than you eat in the course of a day. Instant Knockout can help you resist the urge to eat and it will burn extra calories. It could account for about 300 calories extra per day. If you also have that deficit from your diet you could be losing about 2 pounds a week.

What Kind of Results Can I Expect with Instant Knockout?

That depends greatly on your efforts in the diet and exercise departments. A health diet is critical for successful and sustained weight loss. We also recommend working with a resistance training program at least 3 times a week with either 20 minutes of moderately intense cardio, or high intensity interval training each time.

Why have the Instant Knockout ingredients been chosen?

Like any good weight loss product, the ingredients have been chosen based on scientific evidence. Below are a couple links to the scientific journals for a select few of the ingredients. It’s easy enough to find the results of studies carried out on many different ingredients.
