Kirstie Alley is not telling the truth about her weight -- at least, that's the claim made by one woman who's suing the former "Cheers" star over a weight loss program that Alley endorses.

Los Angeles resident Marina Abramyan filed suit in Los Angeles Superior Court on Friday, claiming that Alley's Organic Liaison Weight Loss Program falsely claims that it caused the actress to lose 100 pounds.

Abramyan accuses Alley and Organic Liaison of making "false and misleading advertising claims that the Organic Liaison Weight Loss Program can cause significant weight loss, Indeed, the advertising and marketing for the Organic Liaison Weight Loss Program creates the uniform, false net-impression that the product is an FDA approved weight loss product capable of easily causing significant weight loss and caused Defendant Kirstie Alley to lose a whopping 100 pounds."

Among the false statements made on the company's website, Abramyan claims, are declarations from the actress stating, "I [Kirstie Alley] am proof of its success I lost one hundred pounds on Organic Liaison" and "I [Kirstie Alley] can assure you that if you follow this program, you'll get healthier, lose weight, and not be 'annoyingly' hungry."

Abramyan says that she ordered the program, but "did not experience any of the benefits Defendants advertised." In reality, she says, Organic Liaison consists of "nothing more than run-of-the-mill fiber and calcium supplements."

The suit goes on to claim that Alley's weight loss is due to other factors -- such as the grueling training regimen she underwent on "Dancing With the Stars."

"Ms. Alley's weight loss is not due to the Organic Liaison Program, but rather, is the result of an above average exercise regimen and extremely low calorie diet, including her time on the television program 'Dancing With the Stars' ('DWTS'), where she spent five to seven hours a day exercising as part of the competition." the suit reads.

Claiming false and misleading advertising, violation of California's civil code and breach of implied contract, the suit is asking that Organic Liaison be prohibited from making its allegedly false claims, plus actual damages, punitive damages, interest, attorneys' fees, and the costs of bringing the suit.

TheWrap was unable to reach Alley's representative for comment.
