CFB creator Eric G. first used estimates on shivering and calorie burn numbers to calculate the number of calories burned during a long cold thermogenesis session while playing video games. The video also shows a “side by side” comparison with the calorie burn numbers of other activities.

Note: we removed this video (it’s still on our YouTube page) because it was originally done back in 2012 and is somewhat outdated and superseded by the more precise “Triple Calorie Burn” experiment, which got exacting numbers using indirect calorimetry.
