My girlfriend and I are millenials as well and we were talking about this too. It really seems like this fat explosion happened overnight. We had a handful of death fats in my class of 400 something in high school. Now those bastards make up a quarter if not half of a high school these days. Then the small fats and chubby kids comprise the rest. Thankfully athletics haven't fallen so short that the athletes look like baby neckbeards.
