Who Is The Brain Behind The Product?

The 3 Week diet system was created by Brain Flatt. He is a sports nutritionist, personal trainer, and health coach. He had a degree in biology at San Diego. He created his 3-week diet system through his wealth of knowledge and experience over the years. He has been the fitness industry since 90’s and owns the REV fitness based in South California.

How Does the 3 Week Diet System work?

The 3 Week diet system works in 4 phases:


The first phase is majorly about detoxing your liver; cleansing your body of all the toxins you’ve built up over time.
The author, Brian Flatt, recommends taking vitamin A, C, and D supplements to maximize results. This helps to detox the liver and cleans off excess fat storage sites in the liver. In this phase, there 17 allowed vegetables and 6 allowed sources of protein which your body needs for maximal function.

This phase is to be followed for 7 days before moving to the next phase. The author advised that this phased should not be missed as it is the most important part of the plan.


Following completion of the first phase,

Once you’ve cleansed your body, you can move on to phase two: a one day fast. Fasting starts after your last meal on the 7th day of the program and lasts just 24 hours.

A quick, fast will give your digestive system the time to clean off the remaining toxins in your body.

Although this may appear easier said that done, but it is something practicable. It requires a strong mind and a positive attitude to go off food for one day, but this is essential for the 3-week diet system to work effectively said, Flatt.


It might sound weird but for three days, you’ll eat a diet that consists of 80% calories from fat. You may be thinking – won’t that make me gain more weight?  Of course No! In fact, this will start signaling your liver to start burning it for fuel. There will be an accelerated metabolism by the liver and this helps in burning off the fat in your belly, your thighs and all over your body.


This starts on the 13th day and ends on the 21st day. In this phase, Brain teaches you how to eat food that is peculiar to your metabolic rate. It teaches you how to calculate your basal metabolic rate and all the food you will be eating will be according to your own body basal metabolism. This helps you achieve your desired shape.
