I'm glad Grandma is eating. I think at her advanced age she should be able to eat whatever she wants. If she were younger I'd say make a whole hearted try with the KD. Kind of like my dad, he's dying, he can eat whatever he wants, whenever he wants, mom gets it for him - be it a banana, crackers with cheese, whatever, so long as he eats something. Its the foodies in the tummy that will keep them going longer, and of course the happiness they have from eating something that actually tastes good!
