U.S. actress Kirstie Alley says she wants to lose the weight she has gained in recent years.

Alley, 59, starred on the classic television comedy "Cheers" and in the "Look Who's Talking" film series.

She has long struggled with her weight and, tipping the scales at more than 200 pounds, became a celebrity spokeswoman for the Jenny Craig weight-loss company. Alley announced in 2006 she had lost 75 pounds.

Shortly after shedding the weight, however, she admits she went back to her poor eating habits and stopped exercising, ultimately putting the pounds she lost back on. She can now be seen trying to lose them again on the reality series "Kirstie Alley's Big Life."

"I'm disgusted with myself!" the actress told Ladies' Home Journal magazine. "I let myself down and, worse than that, I let other people down. People were looking up to me for losing all that weight and then I went and got all chub on them. And I set a bad example for my children. I'm finally ready to pay everybody back."
