Guide Note: The 5 Factor Diet written by Harley Pasternak and contributor Myatt Murphy is a diet plan that follows the guidelines set forth in Pasternak's 2005 book, 5-Factor Fitness.

The diet consists of five small meals per day combined with five workouts per week and a list of five factor food-basics like egg whites, lean poultry and beans in each of the five food categories. All of these factors take place over a five-week time period.

The book contains over 100 pages of low-calorie recipes that each contain five ingredients and take five minutes to prepare.

Also within the book you will find customer testimonials from people like Kanye West, Eva Mendes and John Mayer.

The 5 Factor Diet also contains a bonus section outlining 5-Factor Fitness workouts and a sample of 5-minute workout moves that aim to help readers maximize dieting results during the 25 minute per day, five week diet plan.

Pasternak claims that "My plan is the easiest, most effective exercise program you'll ever use."
