No, my parents never mentioned weight or dieting. They did tell me/siblings the importance of keeping healthy and fit, having a healthy balanced diet and making sure you get plenty of exercise. They were both very active, and encouraged us to be the same. They didn't buy in crisps, sweets or chocolates, or fizzy drinks. Fast food was a rarity, and Mum (an SAHM) cooked everything she could from scratch (she'd make cakes, bread, pickles/preserves, yogurt/butter/cheese and things like biscuits). Diet was mainly Middle Eastern/Mediterranean cuisine at home. There were plates of fruit, dried fruit, nuts/seed and crudités to snack on. Drinks: water, milk, fruit/veg juice or occasionally a little bit of squash/cordial. We had a small-holding with goats etc, so me/siblings were only used to goat milk dairy products - when people would give us chocolate and we'd always be sick (most commercially made dairy-based stuff back then was cows milk based). Took my parents a while to figure that out!
I will add though, that my mum was always very petite and slim (as were all her family), and my dad only put on some weight once he retired...but then addressed that after a diabetes diagnosis and managed to reverse it all. Food was plentiful (Middle Eastern family so we love feeding everyone LOADS of beautiful home cooked food!) and Mum always made sure that everyone was well fed. It was always: eat and enjoy food, stop when you're full, keep the sweet stuff/junk food in moderation, stay strong and active. I love cooking and sharing meals now :)
My parents were horrified seeing some of the "heroin chic" looks in the media during the 90's. They didn't care about fashions, clothes sizes or things like that (obviously they'd dress appropriately for the occasion though!). Enjoying food and keeping healthy/fit was their main thing.
