When I was a kid in the 50's I ate my fill of sweets, and then some, as did the kids I played with, and we weren't obese. But those sweets we filled up on primarliy contained sucrose, table sugar, not the cheaper, enzymatically processed high fructose corn syrup. Obesity is blamed on supersizing, but we ate to our fill back then, stuffed ourselves even. Times may change but kids are always kids.
As I have long suspected obesity is not caused by supersizing alone; it is caused by a drug mislabeled as a food, high fructose corn syrup, dangerous when taken even in moderate amounts. It's in almost everything the food corporations manufacture. I came across this in Wikipedia, "Critics of the extensive use of HFCS in food sweetening argue that the highly processed substance is more harmful to humans than regular sugar, contributing to weight gain by affecting normal appetite functions."
This is what drugs do, they affect normal functions.
Ban HFCS, get sugar cane from Cuba, raise sugar beets locally and let childern eat what they want, but also do as our parents did, force vegetables on them once a day. Children on diets, preposterous! To blame kids and punish them by holding back food, ridiculous; but that's what mom & dad do obeying the teachings of the governmental-corporate food complex, aka, the USDA, the FDA and their educational minions.
Remember Halloween! Nobody could have eaten more candy than we did; we were skinny kids with a big sweet tooth.
