Celebrity physical fitness trainer Jillian Michaels is being sued for alleged false advertising on her diet supplements.

A woman in California is seeking a class-action lawsuit against The Biggest Loser trainer. She filed a case earlier in the week in Los Angeles. The lawsuit claims that the woman, Christie Chistensen, purchased the product Jillian Michaels Maximum Strength Calorie Control in January. She contends that the pills failed to lessen her appetite or lose weight as advertised on the bottle of pills.

Michaels’ endorsement and picture appear on the bottle’s packaging with the title “America’s Toughest Trainer” on the label. The claim? “Two Capsules Before Main Meals and You Lose Weight … That’s It!”

“Ms. Michaels knows better — taking two pills before eating does not miraculously cause weight loss,” states the lawsuit.

Christensen is also hoping to seek a payday from Basic Research in Utah along with ThinCare International, the firms which manufacture and market the weight loss pills from Michaels.

ThinCare released a statement regarding the recent allegations:

“Not only have placebo-controlled, double-blind, published clinical studies been conducted on the active calorie-control compound in Jillian Michaels Maximum Strength Calorie Control, but that research was reviewed by some of the leading weight-loss experts in the world before Jillian would put her name on the product.”

Christensen’s lawsuit seeks “unspecified damages that are not expected to total more than $5 million.” Her suit states she has “struggled with weight loss her entire life” and bought “Calorie Control” because of Michaels’ endorsement.

“She felt like she had been misled and deceived,” said Christensen’s attorney, Melissa Harnett.  “We’re getting calls from many people now as a result of this who claim they had been similarly misled.”

She added: “When it’s a celebrity who has built her fame on telling people that it takes blood, sweat and tears to lose weight and then turns around and capitalizes on that fame by putting out a product that inherently is contrary to the notion that you need to exercise and eat right to lose weight, there’s something wrong with that picture.”
