Carol, it sounds like Tim is a warrior! He should be immensely proud of himself for pushing through, but stubborn can be taken a bit too far (my parents would concur, I refused PKs for a long time until my weight loss leading up to surgery got too much).

Skim milk powder (look in the powdered milk isle of any grocery store)can be added to Ensure or whatever he drinks (even water) to boost the protein levels.

Good luck!
