The Fat Smash Diet is the book-length version of the nutrition and fitness regimen that Dr. Ian K. Smith has used to widespread acclaim on VH1’s weight loss reality show, Celebrity Fit Club. The diet aims to change the dieter's "relationship with food" and get one used to normal exercise forever, without calorie counting.The Fat Smash Diet plan proceeds in four phases that are designed to carry the reader through not only the initial weight loss, but also through a lifetime of weight maintenance and nutrition and exercise habits. If a person who has reached the maintenance phase of the plan regresses, slips up, or otherwise regains weight, Dr. Smith recommends returning to the first phase of the diet for a 10-day period of rehabilitation.
