Kirstie Alley is slamming reports that she’s regained any of the weight she lost on the Jenny Craig diet plan, claiming that she put on 10 pounds in January when she decided not to renew her contract but has since lost it again.

Alley says she stopped working with Jenny Craig, which she considers the “best weight-loss program, bar none,” because the company wanted to go in a “different direction” with advertising. It’s using a more serious, health-conscious approach in ads featuring Queen Latifah, she says.

“I wasn’t the right person to do that. For the past three years, I’ve written most of the commercials. All the commercials I did were based on comedy and self-deprecation. That’s my forte,” says the former star of Cheers and Fat Actress.

Because taking excessive doses of niacin is not healthy, perhaps?

Furthermore, she insists that recent photos of her have been doctored to make her look fatter, and says she may sue the National Enquirer over them. Although maybe she needs to come out of hiding first to show that they were wrong?

Alley also confirmed that she plans to create her own weight-loss program in 2009 and drop another 10-15 pounds on it. Expect saunas and vitamins to feature prominently.
