There were maybe 200 people in the photo, all in bathing suits. I noticed that NONE of the people were overweight. And I don't mean that none of them were obese. None of them were even overweight.
I was in High School from 1975 to 1979. My wife and I could only think of THREE KIDS in our class of 624 who were overweight.
So what changed?
My wife thinks it was the addition of High Fructose Corn Syrup into almost everything. That happened right around that time, I think. Mid-70s.
Being "satiated" isn't it, I don't think. Unless, like the rats in the article, people don't eat a lot of food that tastes like crap. lol
When I was a kid, I didn't stop eating pizza, or a Big Mac, or a Banana Split, or Potato Chips, or Thanksgiving Dinner, because I wasn't hungry anymore. I kept eating long after I was "satiated" because the food tasted so good.
And we never got fat.
