So we agree, then, that a person should dramatically increase his or her activity level throughout the day (e.g. walk the streets). However, I'm going to nitpick and say that you're wrong about the gym. Currently, I burn about 1,000 calories on each trip to the gym, every other day. That's a 500 calorie deficit that I'm adding each day. In addition, my body is using additional calories to rebuild muscle, and the additional muscle is consuming calories to maintain itself. It's kind of like compounding interest.
