What does this mean?

[Deanna]

"Ride like a cyclist. Don't eat like one. Stop your f-ing whining, it's supposed to hurt."

The eating part... don't scarf everything in sight or don't eat a strict regimented diet?

I also think I may start chanting that last sentence when I ride.

Maybe they're referring to some of the gels and less palatable bars we force into ourselves when there's no "real" food to be had on the road.
