Due to 40 days being sick with the flu, I am very weak. I have no strength. I started physical therapy today. The therapist said only a half hour, because I was too weak. Please, can you help me with a diet. Also, I have a slow thyroid, and it is impossible to lose weight. I am 5 2 1/2 tall and weight 162. I went down to 148 lbs. on a veggie diet, I gain 14 lbs in 8 days. Please help me. If you cannot, God bless you for trying. I am 74 old and very active, have many friends. Socially active. We go out quite a bit.
