These could keep Ryan's weight up... as would biscuits and gravy, except for I seem to recall reading earlier that he is a vegetarian.

You need to eat a lot of grits, beans and greens to keep your weight up while riding 90-100 miles every day.

I don't know what "flavor" of vegetarian he is, but if he is open to butter etc, I guess he could still be doing well on the weight.
