It's for health reasons, this person is overweight and sedentary. They currently do none of the cooking or shopping. They can't have takeaways, sweets, chocolates etc. We're not a very sweet tooth house but do get takeaway occasionally. Dinners cooked 6 days a week from scratch reasonably healthy, meat, fish veg etc. If this person now wants to go on a specialist diet, should they source and cook for themselves or do I have to do it basically?? (I'm refusing. That's the Aibu)
