My partner lost so much weight before transplant...nearly 100 lbs in the last years.
He hardly ate anything.
Finally we got him on ensure or carnation B'fast. I added ice cream or milk.
He would eat puddings, and canned fruit. I made soup with bland seasonings. He loved applesauce and canned peaches...I don't know why canned, it was sort of like he went back to his childhood...
It was rough but he made it. He is one year post transplant now.
Oh, and welcometo the forum. Come often, tell us more about how he got sick, maybe we can give some other advice.
Good luck,
