I could hardly eat anything during treatment. I lived on creamy mashed potatoes with butter. Cottage cheese. Egg’s anyway cooked, peanut butter and jelly , banana , power shakes with powdered supplements and boost , apple sauce, baby food jars, soups and noodles, Boost/ ensure cans pack a lot of good calories. I had to FORCE myself to eat. Salt throat rinse several times a day helps.Ask you Doctor about Magic mouthwash. It DOES get better a month or so after treatment. He is in a tough battle but it is winnable.

Make smoothies with protein powder, even with weight gainer protein. And plenty of milkshakes. Very helpful in keeping my weight stable and even gain weight. Good luck to you. Keep a positive attitude, it really helps! God bless!
