Quote of the day:
"Heart rate monitors and websites that claim to tell you how many Calories you are expending are lousy at that job. The problem is that movements that don't affect heart rate can use very significant numbers of Calories over the course of a day.
For instance, simply squatting down to pick something off the floor uses roughly 1/2-1 Calorie depending on how big you are and how far down you squat. Waving your arms when you talk, shifting around in your seat while you work, pacing while on the phone and other "energetic" sorts of behavior can use several hundred calories per day more than calmer behavior, even while you are doing the "same" activities of chatting, working at a desk and using the telephone."
