How many calories or Joules one burns only has an impact with how much food I stuff into my face. Here is a real example
I did 66.5 miles at an average speed of 24.1 mph and used 1682 kJoules. This was a low Zone 2 ride. My bike and I weighed 240 lbs. If I plug those numbers into a calculator online or use calories estimates from any of the online applications, I would overeat.
