We all ate crap (sugar/carbs) as kids in the 60's and virtually no one was fat. It's called "lack of exercise". Video game and cellphone obsession has replaced physical activity.
I am also thinking that there is a lot more processed sugars in our diet. Even bread these days has high fructose corn syrup in it.
It’s almost impossible to out train a poor diet.
Yeah, but back then, we actually had healthy food to eat. Nowadays, if you don't read the label on everything, you are gonna get a LOT of processed garbage (sugar), corn syrup (sugar), and starches (sugar). This is the crap that is killing our kids.
Exercise is good and all, but our bodies weren't designed to handle all this sugary filler that is put into almost everything we buy at a grocery store nowadays.
