I am a 45 yr old female and need to lose 25- 30 lbs. I have, among other things, Celiac's and Diabetes. I need a step by step diet and exercise plan. I need to be told what to eat and how exercise. Can anyone help me? I will eat most foods, not crazy about fish, love chicken and not a great cook. I've tried to take a 1200 calorie diet and replace with gluten...
