That’s how it was in my family, too (with four kids and limited income). Mom controlled the food; a complaint of being hungry before supper either got you an apple or you just headed on out to the garden to pick yourself a handful of peas or something. Soda and chips were a treat, shared out amongst the whole family, so each kid got a moderate amount, not a bag per kid.
As others have said, eating out was a rare treat, not two or three times per week. That’s a huge difference right there, I think - I know when I’m tracking my calories, when we eat out, it’s damned hard to stay within a daily budget compared to eating at home.
Yup, and that’s on a sliding scale - at five, the parents are probably wholly responsible; at 15, much less so.
That too. We couldn’t just eat everything in the house, because it was all for everyone, with limited money to buy more.
I think that’s a big part of it, too. I have two nephews, 13 and eight years old, and I have never, ever seen them drink a glass of water. It’s juice or strawberry milk or soda, always (and multiple glasses). The younger one is FAT, not just a little pudgy, and he has been for years.
I think the parents are responsible for a large part of it, and it comes down to discipline. My fat nephew gets whatever he wants to eat, because he screams bloody murder if he doesn’t get his way. I didn’t eat whatever I wanted when I was a kid, because I wasn’t in charge of the household - my parents set the rules, and that included eating.
