Are you suprised we used to be healthier and thinner many years ago?

It wasn't always Burger King Hamburgers, Dunkin Doughnuts, packaged foods with processed burgers, sweeteners, etc.

I saw several pictures of both my great-parents and grandparents on my dad and mom's side of the family. They were fit, healthier and thinner. They lived much longer and there was no obesity nor high cholesterol nor diabetes. Long ago, we used to eat homemade meals.

Nowadays we see some teens and young adults already suffering obesity and other health issues, eating junk food and microwavable cup noodles. Is it surprising we were healthy people long ago?
