I have family members whose idea of "diet" is what you can and cannot have, that you can have unlimited amouts of "what is good for you" and not a flake, speck or crumb of what is "bad for you". One minute it's have another potato, have more potatoes, potatoes are good for you, potatoes don't make you fat, potatoes are natural they grow in the ground, never shutting up about how few potatotes you eat, sneaking another on your plate while you look away in order to get the potatoes "used up" (here's a clue: Don't make so many potatoes!!!)
So then you get out your carefully budgetted-for on-plan tiny chocolate bar that you've been waiting to treat yourself to and it's "You can't have chocolate on a diet/are you sure you can eat that/you could have had more potatoes instead/that's bad for you/you'll undo all your good work"
The first 100,000 times or so you can grin, change the subject, etc. The next coupla thousand you have little Homer Simpson-style musings in thought bubbles where you drag said person along the street behind you on a motorcycle.

And yes, sadly it is everyone else's "business" if they have to cook and prepare food for me when I am not well enough, I can't just make my own food and tell them to go away.
Oh, and there's no point describing it in alternative ways like eating plan, healthy eating, way of eating, etc. because then they just don't see it as relevant to comply, then it becomes "fussing" and is unimportant and they can just throw butter over it all.

I try to tell her gently that I'm going to keep going about this "the old fashioned way" with diet and exercise. I might not lose 10 pounds in 2 weeks this way, but it's been 3 years and it seems to be working
