They have everything the body needs to survive when my husband was Ill its the only thing that kept him going made sure he drank 3 a day
I look after Arthur now he wont eat after breakfast nothing but a spoon or 2 of food so now I give him 2 of the drinks a day he loves the juices x

Give high calorie snacks frequently.

My husband is in that same space. He eats very little, but does drink one high calorie Ensure each day. He will take one or two bites of food at each meal and says I’m done or that’s enough. He no longer likes food he used to like.
