He is doing PT three times a week to build muscle, which helps with his appetite and I am giving him protein, cheese, creamed potatoes & gravy, even cookies, along with 2 Boost Very High Calorie (530 calories per bottle) every day. He not only hasn't gained weight, he lost a pound as of this morning! What gives! He isn't sick and has been checked out for other issues. He is fine, just won't eat enough! It is very worrisome!
Leave out the dairy products except for butter, and try just meat/potatoes, spaghetti, Hawaiian buns with the meal, hearty soups. Ever read the ingredients on Boost or anything similar? Boost ingredients start out saying "water, sugar, corn syrup, milk protein" and other stuff I can't pronounce.
