MAK, try getting a 4th Scandishake into your husband every day. If you are really lucky 5 would be even better. I know how difficult it is to eat when you arent hungry and are in the recovery phase. But every single day your husband should be taking in at least 2500 calories and 48-64 oz of water. Taking in 3000, 3500 or even 5000 calories daily during recovery isnt too much. His body has been thru the war, when showing a weight loss that means he isnt taking in enough and recovery is even harder. He should continue this high an intake at the least until he hits the first year post rads. Adding some high protein whey powder helps speed healing also.
