Hi notself I just finished treatments last week. when I was told about the tonsil cancer I only weighed 128 pounds. 5foot 7 and actually got down to 100 pounds. I was put on jevity and was drinking up to 6-7 cans and seemed to still lose weight. But today I weighed myself and put on 4 pounds. I bought a cuisnart food processor and making all kinds of puree high calories and super high protein concoctions. Yes use those powders at gnc that is a great base and you can add eas Myoplex which contains 42 grams of high quality protein! I work at a hospital in food and nutrition for years and I am glad I learned what I did with those special diets. keep a positive attitude and he will get through it look so far I think I weighed the least out of most in here so focus on that positive good luck donald
