Where Does This Program Come From?

The 3 Week Diet Plan is a comprehensive diet plan created by Brian Flatt. As a sports nutritionist, personal trainer and health coach, Flatt based his program in science and doesn’t make any false claims about losing 50 pounds in 3 weeks or other unsubstantiated claims. Instead, he promises that if you stick to his 21-day program, you will lose between 12 and 23 pounds.  These results that would normally take 2-3 months to achieve without the program can be gained by following his step-by-step guide to diet and exercise.

  1. Book 1 – Introduction Manual: Book one details not just the basic instructions you need to follow to complete the program but allows lays down the science behind the plan so you can see how it really works.
