I think you misunderstood me. Even if I didn't commute to work, I'd still find time to ride my bike for pleasure/exercise and would need the extra calories anyway. Triathlon is my hobby.
But, according to this
bike calorie calculator, I burn 1800 - 2000 calories on my 35 - 40 mi round trip commute. That's more than "add a few carbs". Of course, everybody's commute is different.
