Instant Knockout Cut Changes

Is it Just for Pros?

So can we learn from MMA or other professional fighters?

It’s no surprise that a growing number of mixed martial artists choose Instant Knockout as their fat burner of choice to cut fat before a weigh-in.

Professional MMA fighter Diego Sanchez continues to use IK throughout his training and leading up to fights. By taking Instant Knockout he was able to cut fat whilst maintaining energy levels . He was able to meet his fighting weight and commented by saying…

The weight started coming off so fast…I was already down to 170 pounds. I was basically as lean as I am going into a fight at 155… I’m able to get this lean right now – 145 is realistic now.

This is a great testimonial for IK and goes to show it can work for professionals, but can it work for the average man or woman? Read our testimonials further into our review to see the results and hear from real people.

Instant Knockout Cut Testimonials

There are a number of real world testimonials from around the world on their website. Whilst some people look like they didn’t really need a fat burner, there are some really interesting results from using this product

We have added a couple of real testimonials below, there are load more on the Instant Knockout website.

The one caveat we have is these testimonials are quite old and haven’t been updated in a while so if you’ve been on any other review site you might have seen some of these already.

Travis Lord – USA

Travis Lord - Instant Knockout BeforeTraivs Lord - Instant Knockout After

Here’s what Travis had to say on the IK website

“Instant Knockout helped me change my body and gave me the extra boost into a new healthy lifestyle.

Like a lot of people, my main reason I was looking for a fat burner that actually worked was because I wasn’t happy with what I saw in the mirror…

…No, it’s not a “miracle cure all” but it’s probably the next best thing. Add in the fact that it has natural ingredients and it becomes a no brainier choice.

I immediately felt more energy and my appetite was definitely suppressed helping me with my portion control.

Not only did I lose weight and burnt off that stubborn fat. I also saw muscle growth and lifting gains in the gym! Which I unheard of with most fat burners. I will definitely continue using it in my fitness journey!

My advice is to not hesitate and just do it. You have nothing to lose from this decision except that extra bit of fat.”

Dan Mack – UK

Dan Mack Instant KnockoutDan Mack Instant Knockout After

Here’s what Dan had to say on the Instant Knockout website.

I ordered a little hesitantly, after trying various fat burners previously which all promised fantastic results immediately but rarely work. I found the price was not overly excessive, especially for a months supply and I was sold on the testimonials from professional athletes and MMA fighters.

Initially not expecting much, I started on day one with my morning pill just before breakfast. Within ten minutes I felt full without taking a bite, naturally I was a little surprised as I did not expect the appetite suppression to take effect so quickly.

I continued throughout the course, sticking strictly to my diet and consuming the four pills daily. I have since started the same plan again to really pin down the difference on and off, there is clearly a big difference and my most recent eight week plan has been much tougher without the appetite suppression.

All in all I would highly recommend instant knockout to anyone struggling to stick to a plan, as much as discipline is important a well engineered supplement makes a world of a difference.

Here’s a great video testimonial from the Roar Ambition site.

How to take Instant Knockout Cut

Following the manufacturer’s recommendations on their website they recommend to take Instant Knockout four times per day, to let it work on your “unsightly fat”.

The recommendation is 1 x capsule first thing in the morning, 1 x capsule before lunch, 1 x capsule in the afternoon and 1 x capsule before your evening meal.

By taking these 4 x capsules throughout the day you are effectively burning fat for longer periods of time, but we would suggest you take a break after 4 weeks, to avoid building up a tolerance.

Taking this fat burner whilst following a healthy diet and regular exercise, will according to the manufacturers “leave you not wanting anything else”.

Important: We always advocate that you talk to your doctor before taking any products like this. Always read the label and follow the manufacturer’s instructions.

My Verdict

The best male fat burner on the market today in my opinion. It’s not just for MMA fighters, boxers or any other martial arts expert. IK can be used by anyone who wants to lose some body fat and get the body they want.

If you’re looking for a thermogenic fat burner that has quality ingredients, without any necessary filler ingredients then I do recommend you give it a try. It’s a very well formulated fat burner and the dosages are well considered.
