Kirstie Alley appeared in shape on "Dr. Oz" on Monday, September 17, and the actress and "Dancing With The Stars: All-Stars" contestant got candid about her struggles with weight and keeping her confidence up.
Alley said she did not start gaining weight until 2004.
"The first thing that happened to me was, I was always very conscious of my weight as an actress, and then I think it was about the end of 2003, I just thought screw it. I just want to be a mom," she told Dr. Oz. "I just want to spend time with my kids. I want to cook for them. I want to take care of them. I want to spend all my time with them and bake with them. Bake."
"What happened was I started baking with them and I started drinking grape sodas," she added. "Do you know I was drinking 12 grape sodas a day? That's when I really started putting on weight."
Alley, now 61, has two children adopted children, William True and Lillie Price. She has claimed in previous interviews that she was around 230 at her heaviest weight.
Since her first time on "Dancing With The Stars" in 2011, Alley has claimed she has lost 100 pounds. She credits the dance show, organic eating and her own diet program, called Organic Liaison, for her weight loss success.
Alley also revealed on "Dr. Oz" that she had a miscarriage at 41 and then she went into early menopause.
"It was hormonally, right as we all know, a rollercoaster," she said. "No one in my family had menopause at age 41. But then no one in my family had been a cocaine addict. I don't know if that had anything to do with it but, you know, I've done some hard living."
"It was more than 10 years after that that I started gaining the weight but that's when I noticed my body really changing and getting screwed up in a weird way. It just became harder to keep the weight off."
Alley said she considered herself lucky in her early years because she was a swimmer and that helped her stay slim and in good health.
"My whole life I could eat whatever I wanted to eat and we ate tons of food," she said. "I was lucky. I had a free ride, basically, until I was 54 and then all hell broke loose. I didn't know what to do because I had these habits of eating a huge amount of food. I wasn't particularly cautious of what I was eating."
Over the course of her appearance on the program, Alley danced with Dr. Oz, showed off her favorite recipes and helped encourage women to lose weight with simple tips and during a trip to the supermarket.
Alley first debuted her slimmed down figure at Malaysian designer Zang Toi's Spring 2012 fashion show during New York City's Fashion Week in September 2011.
Alley is teaming up once again with "Dancing With The Stars" pro Maksim Chmerkovskiy on the upcoming "Dancing With The Stars: All-Stars" season, set to debut on September 24.
