My Dad is having this problem, he is in love with chocolate Boost shakes made with chocolate icecream(the real fat yummy stuff) and then chocolate Boost(he doesn't like Ensure and can tell the difference). Blend it up and yummyville. He sips on it and what he does not want at the time goes in the fridge for a little later.
We are still newbie's (Thanksgiving week) to this since he is newly dx'd w/ advanced inoperable, too far along for pallative chemo or radiation rectal cancer and in hospice care. So I love reading others answers to this question so we can give him healthy nutrition packed variety.
