Although not quite up to par with The Biggest Loser, the Walking The X-Files challenge has now seen me lose a "whopping" 3 pounds, with one pound shed this week. Not an amazing total, but remember all I'm doing is walking an extra 45 minutes a day, without any other changes in diet or exercise.
According to the Medical Review Board, a pound of fat equals 3,500 calories. So assuming my current diet keeps my weight stable, if I burn 3,500 additional calories through exercise, I should lose a pound of weight. That's holding true so far: to burn 3 pounds I'd need to expend 10,500 calories. So far I've burned 10,855 and indeed lost 3 pounds. Spooky!
