My husband was very very thin before all of his treatments and lost 20 lbs that he has not been able to put back on yet. His tube feedings are 7 cans of Jevity 1.2 per day, but they are changing him to Jevity 1.5. He is adding cream cheese, sweetened condensed milk and peanut butter blended with his Jevity both for bulk as well as for added calories and fat. The nutrisionist I spoke to this week said to add some Olive oil also. She did say that the cream cheese probably was not enough calories for the bulk, but Chris said he likes it.
