I don't get this part...
"For example, if a 175 lbs man exercises for a half hour at a moderate pace, he will burn around 270 total calories…according to his machine. For an accurate count, he’d need to subtract around 40 calories from the 270 for the calories he used just by being alive for the half hour."
Why would you need to subtract 40 calories from the 270 for being alive? Wouldn't being alive burn calories instead of add calories. It isn't like he just ate a couple of nuts while working out. edit- I suppose I get it now. The machine is adding 40 calories to the overall work out due to him being alive? So the work out burned 230 and being alive burned 40 calories... Big deal.
