How does Instant Knockout work?

Instant Knockout boxes

Instant Knockout works in three distinct ways to aid in fat loss:

It boosts the body’s metabolic rate

Instant Knockout speeds up the body’s metabolism, encouraging fat burning and therefore reducing the amount of fat stored in the body. It also ensures that your body keeps burning calories, whether you are working out or watching tv. An article from Harvard Health confirms that people with a high metabolism continue to burn calories even during rest.

Reduces cravings

When you continuously reach out for snacks, sometimes unhealthy ones, you make your weight loss journey harder. The long waits between meals can accelerate the need to snack. Instant Knockout keeps you feeling full all day, eliminating the need for snacks.

It boosts energy

This fat burner provides the body with enough power to plow through workouts. It also ensures that you don’t feel overly fatigued after an intense workout.

Instant Knockout benefits

The benefits you can expect from this fat burner are:

  • Increased metabolism leading to fat loss.
  • Higher energy levels.
  • Reduced cravings and better appetite control.
  • A toned, sculptured body.
  • Increased confidence from achieving your dream body.

Ingredients list

instant knockout label

Some of the ingredients in this fat burner include:

  • Green tea extract- This is the most critical ingredient in this formula. It boosts metabolism and encourages the breakdown of stored fat. According to Healthline, green tea contains substances like caffeine and catechins that stimulate the body’s metabolism.
  • Cayenne pepper seeds– Cayenne contains a fat-fighting compound called capsaicin.  This component improves the body’s sensitivity to insulin, raising it as much as 24%, according to some studies.
  • Glucomannan- This ingredient is extracted from the konjac plant. It is a fiber that expands when ingested, and that does not get digested in the stomach. It, therefore, keeps you feeling full for a long time, effectively curbing cravings and improving your appetite.
  • Caffeine Anhydrous– This ingredient stimulates the nervous system to give you strength and power to sustain your workouts. It also sharpens your cognitive abilities making you more alert and focused. Finally, caffeine reduces fatigue and contributes to overall fat burning.
  • Vitamin B12– B vitamins are essential as they help the body to convert food into energy. Vitamin B12 helps to break down fatty acids, improve digestion, and maximize protein synthesis.

Other ingredients in Instant Knockout are:

  • Vitamin B6.
  • GTF Chromium.
  • Zinc.
  • Piperine.
  • Green coffee bean.

Instant Knockout user reviews

instant knockout fat burner

Here are some testimonials from people who have used Instant Knockout:

Costas from Greece says:

‘I was severely frustrated when I discovered the Instant Knockout. I tried several things, including visiting a nutritionist and some “popular” weight loss products without success. I have been using Instant Knockout for three and a half months now, and I can tell you this stuff is magical. I’m losing 2 – 2.5 kg (4.5 – 5.5 pounds) per month without any side effects, and the results are a constant month in, month out.’

Maz from Australia reports:

I decided to try Instant Knockout after trying several other fat burners, and after tons of research, I took the leap. Boy, am I glad I did! I had increased energy, stopped eating out of boredom, and felt so much stronger at the gym. I was on fire! I can’t believe I was once 25kg heavier and now able to be on stage!’

Nick from the USA adds:

Upon starting the first month of Instant Knockout, I immediately felt a difference in metabolic rate. The steady supply of caffeine in each pill kept me energized and more focused. In a single month, I went from 187 pounds down to 179 while strength training.’
