I had the same problem with
weight loss during tx. I have only gained 5 lbs of it back since stopping tx
3 1/2 months ago. Way too thin!
After the weight loss began I ate a lot of ice cream, cookies, cakes, chips, pancakes, pasta, peanut butter sandwiches,etc and all foods with high calorie content. It did not help much and I did manage to gain a few lbs, but I strongly feel eating that way kept me from losing more weight.
