I'm a breast cancer survivor and I take a hormone blocker medication to help prevent reoccurrence. I'm also 64 with thyroid disease. Weight loss is extremely difficult. I can gain a pound a day easily but only lose a half pound a week, on a good week. Anyone else in the same boat? What are your tips to improve results? I'm active, walking, elliptical, weights and stretches. I'm on the blue plan. Purple is only good for maintaining for me.
