Well, I'm not sure - do I understand that in both cases, the speed is
4mph?

I do recall reading years ago that walking supposedly burned more
calories than jogging. Walking was considered "less" efficient.

Or in other words, I have no idea!

Ok, one for you gurus ... if there even is an explanation. And if there is,
please give it to me in terms I can understand. g

I'm using the diet program Lesanne has spoken about and noticed what I think is a
*quirk* ... maybe it is, maybe it isn't, I don't have a clue. But since this is
automatically calculated based on my weight and height along with the info I add
(miles/time), I'm making an assumption that there must be some kind of a
difference in these activities. So here goes ... I work out on the treadmill,
which is a speed factored activity (so this program tells me). This program says
that someone my weight and height will burn 0.0874 calories/minute if walking at
roughly 4MPH. BUT ... if going for a non speed factored brisk walk at 4MPH (15
miles per minute) it says I will burn at a rate of 0.03174/minute. Can anyone
explain to me why the difference rate of caloric expenditure between the two
activities? Or is it solely because on a treadmill it is a constant, automated
speed?

I am sooooooooooo confused! g
