Instant Knockout

For most people, the goal of working out is to get a leaner, healthier, more toned body.

Sometimes, even with the best workouts and diet, stubborn fat might linger, leading to frustration.

If you find yourself experiencing this, then you might want to look into Instant Knockout.

Instant Knockout is a fat burning supplement made to complement your fitness journey by accelerating fat burning.

It acts as that little ‘something’ that takes on the stubborn fat in your stomach, thighs, arms, and buttocks, melting it all down and leaving you looking leaner and sexier than ever before.

This super fat burner, initially designed for MMA fighters, is now available for both men and women who are looking to erase the most stubborn fat.

Instant Knockout is highly endorsed by MMA fighter Diego Sanchez who dropped two weight classes, becoming the lightest he has ever been.

He credits Instant Knockout for this amazing feat.

You must be wondering whether this fat burner is a miracle pill.

In fact, it is not, but its manufacturers have given it all they can to ensure that it works miracles.

Instant Knockout is made from 10 powerful ingredients that complement each other, resulting in one of the best fat burners in the market today.

All the ingredients are natural and carefully selected to bring you the following three benefits:

  • Burn fat.
  • Suppress appetite.
  • Boost energy.

For best results, it is recommended that you take four capsules per day.

Instant Knockout is manufactured by Roar Ambition and ships worldwide out of the UK and the US.

It is available to order from the main website www.instantknockout.com and comes with a 90-day money-back guarantee.

How it works?

The makers of Instant Knockout rely on one simple fact- if your body has a faster metabolism, it will not store fat.

Instant Knockout works by combining powerful ingredients to boost your metabolism, helping you burn more fat.

When you burn fat, you create energy, allowing you to do even more in the gym.

This is how you get that toned body.

Here are the three top ingredients found in this fat burner that make it so effective:

Green Tea Extract

This ingredient3 is packed with catechins that ramp up metabolism and break down stored fat converting it to energy.

Cayenne pepper4 contains a fat-fighting alkaloid called capsaicin.

This alkaloid improves the body’s sensitivity to insulin, which in turn impacts fat storage in the body.

Cayenne pepper is also thermogenic, which means it improves the body’s metabolism allowing you to burn more fat.


Extracted from the konjac plant, this ingredient helps to lower cravings and reduce appetite.

Glucomannan5 is a fiber that passes the stomach without being digested. It also absorbs water in the stomach, making you feel fuller for longer.

Pros & cons

  • Made from natural ingredients.
  • Contains an effective dose of all ingredients.

This is because it combines the power of five weight loss pills in one, working from all angles to ensure that you lose all unwanted fat.

PhenQ is especially useful for those who are looking to lose stubborn fat in the stomach and thighs and can be used by both men and women.

Other than helping burn fat, PhenQ also boosts energy and improves moods, suppresses appetite, and stops the production of new fat in the body.

The secret to PhenQ’s success is a powerful, clinically tested formula called α-Lacys Reset®.

Studies have shown that this formula can decrease body weight and fat while increasing muscle mass.

One study saw subjects taking α-Lacys Reset® lose body fat by 7.24% and body weight by 3.44% compared to those taking a placebo.

It is recommended that you take two pills in a day, one with your breakfast and one with lunch.

This fat burner is available on the official website and offers free shipping on all orders worldwide.

PhenQ is manufactured in FDA approved labs by Wolfson Berg Ltd, a supplements company based in Cyprus.

3. LeanBean


The majority of fat burning supplements in the market are made for both men and women.

As a result, they don’t take into account that men and women are different when it comes to fat loss.

For instance, women are more likely to have cravings triggered by emotions or the environment around them.

As such, the one size fits all supplements do not address such specific issues, and they, therefore, might not be as effective as required.

Leanbean is the fat burner that women have been waiting for.

It is specifically formulated with women in mind.

It relies on ten natural ingredients to produce excellent results with no side effects.

Ex pro-surfer and model Bree Kleintop highly recommends Leanbean because it suppresses her appetite and keeps her energized.

It is recommended that you take 2 capsules three times per day with plenty of water.

Leanbean is manufactured in the UK by Ultimate Life Ltd.

It ships worldwide and offers free shipping if you purchase two bottles and above.

How it works?

Leanbean combines a host of powerful ingredients to work in three main ways:

  • Helps overcome cravings: as mentioned, women are prone to sugar cravings more than men. Leanbean contains ingredients that help you stay full, reducing your cravings. If you are not eating all the time, you are likely to lose weight.
  • Increases energy and metabolism: a slow metabolism means that the body is burning calories slowly. When a body burns calories slowly, most of it ends up being stored as fat, resulting in weight gain. Leanbean contains ingredients that help to increase the body’s fat-burning ability while balancing blood sugar levels.
  • Boosts energy: life can be hectic, and it is tough trying to balance everything. When you add dieting and exercise to the equation, you might end up being fatigued and tired. Leanbean contains natural caffeine to ensure that your energy stays up, enabling you to keep up with training. This helps to maximize the effects of fat burning, resulting in a toned, sexy body.

Here are the three top ingredients found in this fat burner that make it so effective:


This is the main ingredient in Leanbean.

Extracted from the Konjac root, this ingredient forms a gel in the stomach, keeping you satiated for longer periods.


Choline is a nutrient that is helpful in removal of cholesterol in the body8.

Chromium Picolinate

This essential mineral supports metabolism and also aids in the maintenance of blood sugar levels.

Pros & cons
  • Specifically formulated for women.
  • Made from natural ingredients.
  • Has no side effects.
  • Does not contain pure caffeine.
  • Suitable for vegans and vegetarians.
  • Requires one to take six capsules per day.

4. Clenbutrol


Clenbutrol is a powerful fat burner that works fast to meltdown excess body fat and improve cardiovascular performance.

Some controversy has surrounded this fat burner, and it is important to clear the air before moving on.

Clenbutrol is an alternative to Clenbuterol9, which is banned in the USA.

Clenbuterol was a powerful weight loss aid that worked by increasing the body’s metabolism and performance.

It was originally designed as an asthma drug but was widely used by bodybuilders and athletes for its fat-burning qualities.

It also became very popular with celebrities.

It, however, had adverse side effects, including heart palpitations, abnormal sweating, shaking and anxiety.

Clenbuterol has since been banned by the FDA and the World Anti-doping Agency.

Not wanting to give up on its excellent qualities altogether, Crazy Bulk, manufacturers of many other health supplements, came up with a safe, natural alternative- Clenbutrol.

Clenbutrol is safe and legal, not to mention one of the most potent fat burners out there.

You are advised to take three capsules with water 45 minutes before your workout.

How it works?

This powerful fat burner takes advantage of its thermogenic qualities to increase the body’s internal temperature.

When the body’s temperature goes up, the metabolic rate rises.

This, in turn, triggers the body to ‘look’ for more energy to keep up, and it does this by reaching out to the stored fat.

When this fat is broken down into energy, you will be left with a lean, ripped body.

Clenbutrol also improves your cardiovascular performance, allowing more oxygen to be transported throughout your body.

This gives you more energy and helps you get through even the most demanding of workouts.

Here are the three top ingredients found in this fat burner that make it so effective:

Garcinia Cambogia

This tropical fruit blocs the body’s ability to make fat and is also quite useful in reducing appetite10.

Bitter Orange Extract

Bitter orange extract is used in weight loss supplements for its ability to raise the heart rate. It also helps to curb the appetite.

Guarana extract

Guarana11 is a rich source of caffeine and also contains tons of antioxidants. Caffeine helps you to stay alert during workouts as well as keeping you energized.

Pros & cons
  • It can be combined with other supplements for even better results.
  • It is made from natural ingredients.
  • Results are visible within the first 30 days.
  • Preserves lean muscle mass.
  • Legal and FDA approved.
  • Trade name has a bad reputation due to the banned original Clenbuterol.
  • Some users may experience disruptions in sleeping patterns.

5. Performance Lab Fat Burner

Performance Lab Fat Burner

If you are an avid trainer, hitting the weights hard on you way to a sculptured body, then Performance Lab Fat Burner is for you.

This fat burner is designed to cut out all excess fat while maintaining and building up muscle mass.

It is especially successful when combined with fasted training- which means working out on an empty stomach.

Research shows that fasted training improves fat burning, especially in stubborn areas such as the stomach and thighs.

Performance Lab Fat Burner contains four main ingredients that work together to burn fat, boost energy levels, and suppress appetite.

These ingredients have been clinically researched to ensure effectiveness.

Because they are natural and safe, you can continue using Performance Lab Fat Burner daily on the long term without having to stop for an amount of time.

This fat burner can also be combined with other Performance Lab supplements, either pre or post-workout.

The manufacturer recommends that you take 2-4 capsules about 15 minutes before your workout.

Performance Lab Fat Burner is available for purchase on www.performancelab.com and ships worldwide.

How it works?

Performance Lab Fat Burner works in three main ways:

  • Burns fat: the ingredients used stimulates fat-splitting and fat-burning enzymes in the body, turning it into a 24-hour furnace.
  • Boosts energy: this fat burner increases energy expenditure in the body, especially during exercise.
  • Promotes muscle growth: the ingredients are designed to preserve muscle mass even during a fasted workout.

Here are the three top ingredients found in this fat burner that make it so effective:

HMB (ß-Hydroxy ß-Methyl butyrate)

One downside of fasted training is the possibility of degraded muscle mass.

HMB helps by neutralizing the damaging muscle enzymes that might be generated during a fasted workout.

It also optimizes oxygen consumption in the body as well as delaying the onset of lactic acid, allowing you to work out better for longer.

Properties in HMB encourage the body to use stored fat as fuel, as opposed to muscle tissue, when the body is in a calorie deficit.

Coleus Forskohlii

This natural root contains an active ingredient called Forskolin12.

Forskolin activates specific enzymes in the body which in turn help in regulating metabolism, increasing thermogenesis and promoting muscle growth.

It also aids in the breakdown of body fat.

Cayenne Pepper Extract

Cayenne pepper contains an active ingredient called capsaicin.

Capsaicin is responsible for the fat-burning effect in cayenne pepper.

The result of this is increased energy expenditure in the body, meaning that you burn more calories during a workout.

It also contributes to fat oxidization and mobilization before and after exercise.

Pros & cons
  • Made from natural ingredients.
  • Ideal for vegans.
  • Does not contain caffeine.
  • Gluten and soy-free.
  • Can be taken in the long term.
