Re: [Phys-l] Food Liar's calorie chart



What "you" (SJ) forget is the basal metabolism, and the increase of the metabolism due to 'work" which is not contributing to the muscle work. These are not increased much w/ harder exercise. The only way to measure all this is to wear a CO2 monitor basally, while exercising, and immediately after exercising.

bc not certain about this.

Equating body weight with force in the direction of displacement
is suspect on the face of it.
I have also read suggestions that the energetic cost of moving is
proportional more to time than to distance, so that I read of folks
being encouraged to walk at any speed for set time periods
as a slimming strategy.
