I started a jogging program about 5 weeks ago. Previously I had little extra activity except from my job and chasing my kids. I am now up to running about 20 minutes a day and have been watching my calories. About 1500 - 1600 / day. I lost 7.5 lbs in the first three weeks and haven't dropped a lb since. I have gotten to this plateau before, become discouraged and quit, but I really want to continue. Any ideas to start losing again? My pants feel looser and I have more energy but it's frustrating. I weigh 198, 5'6". I have polycystic ovary syndrome and hypothyroid going against me per my endo. My boss says maybe I'm changing my fat into muscle and muscle weighs more. any truth to her theory.
