I noticed it when my children were in school.
I looked back to over 40 years ago when I was in school and the 'fat kid' was nowhere near the size of what is considered normal these days.
It's consumerism, cheap food...
Without sounding like a dinosaur - we had 3 meals a day. A breakfast covered in sugar or containing sugar... It didn't matter because that's all that was fuelling you until school lunch time. A packed lunch of primula spread sandwiches, cheap crisps, cheap bar of chocolate and squash in a refillable bottle (more shit). Dinner - home cooked chips in the chip pan, sliced white bread and butter, probably some awful processed meat and processed peas.
UPF heaven.
Nobody was overweight. Pudding was fruit. It was an unwritten rule that if you took any crisps or chocolate that were destined for packed lunch then there'd be hell. If you were hungry, it was toast and marg, or an apple.
I don't think people let themselves get hungry these days.
My stomach would be growling from 10am, but I had to wait until 12. Again growling but had to wait until 5pm. I do remember thinking a while back that it doesn't happen any more because there's always a snack.
We didn't have a microwave either so chip pan or not it was real peeled potatoes etc...
I don't know where I'm going with this...
Oh yeah, so the obese kid at school was probably half the size of normal now.
