I visit family in other states and I get comments like “I can’t believe you are so thin.” For context I am a healthy weight and I eat what I consider a reasonable diet. I sit and smile while I watch them drink soda and eat pure sugar and salt. I don’t care about your life choices but don’t act surprised by someone that’s a normal weight.
I know exactly what you mean! Having raised kids, and now grandkids, this problem can come up often!
My only suggestion here (for anyone), is to make less than you think you can eat, and then have simple sides or snacks to cover any shortfalls. It’s far too easy to over prepare meals, so you do bring up a good point!
