If you’re fat and too lazy to do the bare minimum, fine, don’t go to Mars. That has nothing to do with Mars being a harsh place to live, and everything to do with the person in question not caring enough.
In microgravity? It might as well be. The effects are far more accelerated compared to living in 38%. The point stands.
