dayberndt - I can loose weight at 700 to 800 calories a day. I can maintain my weight at 1200 - 1400 calories a day. Above 1500, I gain weight. I have a friend that went through breast cancer, surgery, radiation, chemo and reconstruction. I know how difficult it is. She has been cancer free for 6 years. Congrats to you. You have made it past the critical time.
