I'm fortunate in that my relatives aren't that well-meaning.

Seriously though, those that don't agree with me about diet, humour me. Friends can be more difficult. This summer when a friend told me to lighten up and have a marshmallow, I told him that around the time I started eating more ketogenically, I stopped hearing voices. For all I know, it could have been a coincidence, but he stopped pushing the marshmallows.

I think sharing food is downright instinctive. Our ancestors didn't have to worry much about what they were doing to each other's blood sugar.
