Subject: RE: Logging of Calories Burned...Bodygem is a test of resting metabolic rate inferred from your rate of oxygen intake vs co2 output. Here's the company/site http://www.healthetech.com/bodygem/ I mentioned that only because there are like 12 different ways to calculate your RMR/BMR and the numbers can be very different. The most commonly used one is the Harris-Benedict formula, but there are several others including things like the Bodygem that attempt to measure it. Each has it's flaws. (For example, the Harris-Benedict method doesn't take into account body fat percentage, and since muscle burns more calories than fat it can be off for someone who is muscular.) Since part of calories burned is just keeping your heart beating, it seems useful to have a default calculation but allow a user to override that base number. The calories per activity stay relatively the same and are generally based on weight. |
