Kirstie Alley says that miscarrying her only pregnancy at 3 months along in 1990 was the beginning of her weight gain. In her new book, Kirstie writes, "When the baby was gone, I just didn’t really get over it. Neither did my body. I so throughly convinced my body that it was still pregnant after nine months that I had milk coming from my breasts. I was still fat, I was still grieving, and I had just been told it was very possible I would never be able to have children. Fat, childless, with little hope for any future children…that’s when I began to get fat."
Kirstie has since adopted William, 12, and Lillie, 10.
