The 2 Week Diet focuses on three main components to help dieters lose unwanted weight: diet, exercise, and mindset. Dieters learn what, when, and how to eat for optimized weight loss. They also receive supplement and exercise advice to accelerate the process. Finally, they develop the mindset—or willpower—to lose weight and keep it off. Brian Flatt, nutrition coach and owner of R.E.V. Fitness, developed the 2 Week Diet in Southern California.
