Trainer Jillian Michaels helps contestants lose weight the old fashioned way on 'The Biggest Loser,' but her new diet supplement has been labeled "worthless" in a class action lawsuit, according to TMZ.

"Telling people you take two magic pills and then eat chocolate cake all day is a deception," said the lawyer who filed the suit against Michaels. She is being sued for false advertising by a woman who bought the diet supplement, Jillian Michaels' Maximum Strength Calorie Control.
