Kirstie Alley says love of butter led to newly "schlumpy" body

's pain, I really do. Losing the weight, then gaining the weight.

Been there, doing that.

But how did it happen to a celebrity who had all the resources in the world at her beck and call?

It happened just like it does to us real folks. Alley tells all to People magazine in the issue hitting newsstands on Friday.

During her three-year stint as a Jenny Craig spokeswoman, Alley lost and kept off 75 pounds. Remember her showing off the results in a bikini on Oprah's show?

But the wheels fell off the cart when she and Jenny parted ways in 2007. The gym equipment got banished to the garage and she left behind those healthy, low-calorie portions and took up again with Chinese takeout and pasta drenched in butter, she tells People.

People Alley

: "It started with New Year’s [2008], right after leaving Jenny Craig. When you’re a spokesperson for Jenny Craig, there’s responsibility. You have a person every week standing over you when you get on the scale, and I did it naked because those panties could weigh 30 lbs.! It was amazingly successful. But the first nail in the coffin was that I didn’t have to weigh in. I just sort of went wild."

People Alley

: "It wasn’t the exact same M.O. My food demons are Chinese food, sugar, butter. A lot of butter. If I’m at the movies, usually I eat popcorn without butter, but I’d say, "I’m at the movies, so who cares?" And toast with butter. Or let’s say I had two cups of pasta and six tablespoons of butter on it. There was a lot of butter going on."


: What weight do you want to get down to? Alley: "I have to be below 140 to really look good. I have to work my legs like crazy. Actually, do you want my real goal? My real goal’s always too low. I love the way I look at, like, 128. One time on Cheers, I weighed about 148 lbs., and they told me to lose, like, 20 lbs. Now, I’m 5'8", so at 148 lbs., I wasn’t fat. But they’re saying, 'You know, you need to lose 20 lbs.' So what does that put me at? 128. That’s where I keep getting this number."
