Who said anything about being a champion? Why should this be the goal? Other than the media you've consumed has told you that "you must be a cHAmPiOn in LiFe" to be important.

Fuck that, everything in moderation. I love donuts, being fit and shying away from donuts was a miserable experience. So what, I might die earlier having eaten that donut? Worth it.

Everything in moderation. Good and bad.

At the end of the day, none of this matters. Wy put arbitrary constraints on your short life of pleasure.
