The fat smash diet was created for a VH1 show called Celebrity Fit Club, created by the diet's author Dr. Ian Smith. The diet relies on improving eating and exercise habits.

Ian Smith's resume prior to creating the fat smash diet is impressive. He graduated from Harvard, is a medical contributor to the view television program, a medical columnist for men's health magazine, and sits on the Board of Directors of the American Council on exercise. Celebrity Fit Club, the show he created and for which he served as head judge, was based on the fat smash diet.

There are four phases within the fat smash diet:

One – detox: During this nine day phase of the fat smash diet people purge their bodies and minds of bad things, while losing up to six pounds. Dr. Smith had some strangely useless suggestions for this phase such as walking around naked.

Two – foundation: Some foods removed during detox are reintegrated during this three week phase in the smash diet. This is all based on controlling portions, such as eating 3 ounces of meat.

Three – construction: This a four-week phase is a time during which the dieter creates an eating plan that incorporates foods they enjoy. Moderation is important when things like sweets and breads are added back to the diet.

Four – Temple: This part of the fat smash diet lasts a life time. The temple built in the first three phases must now be maintained through will power and control.

Fat smash diet has both good and bad aspects.

The initial 6 to 10 pound weight loss is really due to severe calorie cutting which can be dangerous. Many experts find that nine day detox phase to be troubling. However the lessons of moderation and exercise proposed by the fat smash diet are good ones.
