I haven't read ANY of the thread apart from the OP.
My Mum was considered the fat kid at school in the 50/60s.
We all had a fat kid at school during the 80s and 90s.
Looking back at photos now, those werent kids fat at all! They were larger than us, but having had 2 children go through primary and secondary during 2000/2010 - their obese equates today's normal.
There has been a HUGE rise in obesity.
Me and my brother, brought up through the 80s knew how to use the chip pan, bread and butter was a staple on the table. Chip butties ahoy! We'd gave whatever with chips, usually luncheon meat and a fried egg.
Pudding being an Instant Whip.
So, we were full of sugar and carbs, but were normal weight. Not skinny, not fat.
It had to be the indrofduction of the microwave, the additives, preservatives, and ready meals surely.
Ps the fat kid at school now looks thin compared to me!
