How to Follow Dr. Ian's Phase 1 of the Fat Smash Diet

Dr. Ian Smith's Fat Smash diet leads followers through a four-phase weight-loss program. According to Smith, the plan helps dieters develop habits that contribute to a healthy, sustainable lifestyle. The first phase -- called the "Detox" phase -- lasts nine days and strictly limits the types of foods you can eat, as well as the portion sizes of some foods. American Dietetic Association spokeswoman Tara Gidus told "Health" magazine that she praises the Fat Smash diet for encouraging dieters to consume more produce and whole grains but worries many people won't be able to complete the diet's restrictive Phase 1.
