Marvel villains and obesity

I think it was in the first avengers movie that they talk about how the villains in the world were becoming bigger and stronger – as the super heros did that too.

In some ways, the strength of the super heros was attracting bigger and strong villains. Creating a vicious cycle that ultimately crescendoed in End Game.

When I read about obesity, I see something similar happen in the degenerate case.

It’s like you eat more, then your body adapts to that, and the hormones go out of whack. There was something along those lines. I forgot the premise now.
