Jeopardy Knowledge:

1 pound of fat = 3,500 calories.  So if you have a 500 calorie deficit per day you would lose a pound a week.
In the last year I have lost 57 pounds which means that is 199,500 calories that I have given up, which is approximately the equivalent of eating 1 Big Mac per day for 1 year.

On a side note I got to the gym this morning...30 minutes of cardio and 448 calories burned and feeling good!
