    Can you tell us what you did, Dr. Kruse?

    Any guesses from the forum members?

    I am guessing that the 3800 calories is calculated from the idea that 15 minutes in cold can activate sufficient BAT to liberate over 300 calories of heat, like one would experience when running a mile. (I wrote that into my notes some time ago, but neglected to get a cite on the source. Sorry.)

    I was packed in ice that day and used some rudimentary math to come up with my burn rate based upon variable Ray Cronise has shared......nothing scientific but I can say I burned more than someone running a marathon and did so with no wear and tear on my body.
