Jessica Alba, Jessica Biel Join Kimmel's Diet Craze

A new diet craze has taken Hollywood by storm - all thanks to funnyman Jimmy Kimmel.

Following the late-night host's "Hottie Body Humpilates" spoof, Kimmel debuted the second half of his "revolutionary fitness regimen" last night (March 14).

Jimmy was joined by a bevy of A-list beauties such as Jessica Biel, Scarlett Johansson and Jessica Alba, who claim to follow the mock diet plan and boast about weight loss with "before" photos that feature the actress' faces photoshopped onto overweight bodies.

The Jimmy K plan advertises a fool-proof plan for weight loss, saying, "Fattening foods are subjected to powerful slimming forces which strip away 80% of the carbohydrates, proteins and fats and divert them directly into Jimmy's stomach, where they are digested,"
