Kirstie Alley is just plain crazy and has no realistic goals. She is picking a weight from 30 years ago. As you can see from this quote Hollywood ruined her body perception.
What weight do you want to get down to? 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.
