This is mostly for George, but if any other resident geeks are out there and know the answer, feel free to chime in yourselves! How long does it take for the exercise you are doing that is burning calories to result in weight loss? Does it burn as it goes, or does it take a few hours? I had 35 minutes to think as I walked as fast as I could move to my meeting today, and got to hoping the energy I was using would show up on the scale. I also had the same thought earlier as I wrestled for almost 2 hours taking xrays on an 135 pound Rottweiler at work today. Even an sedated 135 pound dog is quite a workout to take elbow, shoulder, knee and hip films on, especially when your machine is antiquated and you have to repeat ALL of them at least once. I thought about halfway through, this workout better pay off this evening!
