I think you can be temporarily fit while eating unhealthy, but eventually it will render you unfit. That still might be the optimal fitness choice for people, depending on their time preference (which I thought about, but didn't include in the post).

Right exactly fitness is u can do stuff regardless if u have the body.

So you can eat unhealthy but be fit.

You can be healthy but totally weak and unfit

What Even is "Fitness"?

Undisciplined

I didn't say it explicitly, but I was partially pushing back on the idea that being fit means looking like a body builder or model. For most of us, that's pretty useless (unless you just enjoy the pursuit).
