When my doctor told me how much my blood-sugar levels had decreased, I couldn’t believe it.

In the regular American diet, we eat a lot of carbs, even in things that you don’t consider:

  • Bread
  • Potatoes and chips
  • Fruit (yes, fruit!)
  • Grains

Those are just to name a few. Now, most of them are actually OK. However, because we eat so many simple carbs, like refined sugar or bread, or body then doesn’t know how to process them correctly. That’s my many people suffer from Type-2 diabetes.

Now, no one tells us this, and we go through life thinking that we’re destined to be fat. However, after reading a review of the 3 Week Diet, and seeing its refund guarantee, I decided to give it a go.

Here’s the thing, I had completed many other diet programs. So, I knew I had the discipline. But you know, as well as I do, how frustrating it is to not see results. It’s easier to give up.

But, I liked their confidence in their program, and I figured I could always get my money back. Well, if you do the research, you’ll find out about all the great benefits of temporarily reducing your carb intake and practicing intermittent fasting.

In the end, I lost around 30 pounds after three weeks. So, I decided to take it a little further. Here’s how it went…

About The 3 Week Diet by Brian Flatt

truth of the 3 week diet,and a woman lifting her hands

The 3 Week Diet system is a diet system that is brand new. A system that is slowly but surely making a revolution in the way of dieting of people and their weight loss.

In essence, it works by “reprogramming” your metabolism to use fat, instead of carbs, for energy. You see, most of our energy comes from carbohydrates. When we consume a lot, our body stores the excess as fat. The idea is that this fat is meant to be used as energy when there are no carbs available. So, if you reduce, or remove carbs, you’ll start using fat as energy.

Yes, it’s really that simple. However, not many people dare to do that. Why? Because we’re addicted to sugars!

So, this program helps you navigate your need for carbs, use fat as energy, and start losing weight.

However, a great personal benefit was the fact that it also helps you rebalance insulin and ghrelin. What are these? Well, insulin is the hormone that stores fat. The more carbs you eat, the more insulin you produce.

If you eat a lot of carbs, you produce a lot of insulin. The problem is that, at some point, your body can’t keep with this unnatural carb intake. That’s what can lead to Type-2 diabetes.

I had this book for a couple of weeks and read the entire book it in one sitting. I actually love it. Being someone that has always battled with my weight I’ve read it all and heard it all when it comes to diets so I thought this was just another diet book.

The 3 Week diet program has gained popularity in a very short space of time. The program was only developed back in 2015. It is basically a weight loss program that aims to achieve results very quickly. This diet program is designed so you lose weight fast – between 12-20 lbs in just 21 days – as long as you follow the diet to the letter.

Excellent diet system

on 2017-09-28 09:18:30

This new diet suitable for anyone who wants quick weight loss. This is a distinct diet system to make the body store the fat already existing for energy requirements. It’s a 4-part diet guide to help users better understand the science behind the system. I tried this and it is proven to be safe and effective. But this is not good for Vegans, vegetarians having difficulty with the detox phase and individuals on medically controlled diets (including diabetics) are not recommended to try the 3 Week Diet.
