Hi, I'm 27 years old. I have always been skinny until I had my daughter my second child. I went to the doctors because I was having some huge problems with my menstrual cycle. Anyway I was diagnosised with pcos and thyroid conditions. I really want to lose all the weight I have gained since then. I'm 5ft 175lbs. Has any one ever lost that much weight with both these problems stacked against them. I'm starting today. My goal is to get to 120 lbs would be thankful for 140. I know the goal is to burn more calories then you consume but im always hungry.
