"I've gone down two jean sizes. It's been really great.
"The program is really easy. It's a real help right now in my busy, busy life with my three boys. I don't have to think too hard about it. It's done for me. I just get to enjoy my meal."
The former 'Sabrina the Teenage Witch' star, admitted she has "done a lot of different diets" in the past, but hopes to lead a healthier lifestyle now with the help of her husband.
She said: "My husband is really into fitness, and I've always been big into working out. He's very supportive and gets me out for runs here and there to keep me active. My boys keep me active as it is."
