I want to lose another seven and I'll do that over time."I've struggled with my weight for my entire life. I've been fat and I've been thin. As you know, I got the lap-band and lost a ton of weight, but it made me so sick. That's why I had to remove it. But when I removed it, I gained about 45 pounds, And as my 60th birthday was approaching, I didn't want to be overweight. I wanted to be healthy and keep with my family. I want to be healthy and enjoy life.""That's when Atkins approached me about possibly doing this and I was like, 'Where do I sign?' It has been a life changing experience."It's really not a diet. It's a lifestyle change."Sharon - who has three children with rocker husband Ozzy as well as a baby granddaughter Pearl - recently revealed she feels "blessed" with her life and is thrilled to have the support of her family members.She said: "[Son] Jack and [husband] Ozzy are doing the diet along with me and my one assistant. They love it because it is so convenient. It's so yummy. It's all about proteins and vegetables. You can go out to eat and you can have scrambled eggs, sausage, bacon, or a salad. On the diet, it's very broad what you can eat."
