Grandfather only drinking Up and Go's (HELP for healthier alternatives) https://ift.tt/eA8V8J

Recently my grandfather (71 years old) moved in , and we have come to find out his diet purely consists of up and go's. We've tried giving him actual food and removing the up and go's from him, but he has gotten to the point where he trashes the food and gets my brother-in-law to buy the drink in secret. What can we get him/or make for him that gives him everything he needs (like nutrients, proteins , and etc) but still a liquid diet as the whole family thinks his senile ways will be the death of him.

For you all non anz people, Up and go's are advertised as breakfast to go drinks that are filled with sugar.
