With this site as my guide, not doctrine, I've calculated that just by sports alone, I will be burning a minimum of 2413 calories every week. This week I have one extra game, so I will be burning an additional 905 calories. Bringing this weeks total to 3318 calories burned just by being active.

Now, if we factor in sleeping. That makes 570 per night (average of 7 hours). Weekly total of 3990.

Sports:          2413
Sleep:           3990
Grand Total: 6403

*Calories burned during daily activity were not accounted for.

I can see why I gain weight during the winter. Every week there are 1810 calories with nowhere to go.

All that's left is to add in the missing...
