How does the bodybugg™ measure calorie expenditure?
the bodybugg™ has 4 main measurement components: 1) accelerometer, 2) heat flux, 3) galvanic skin response, 4) skin temperature. Our technology partner, BodyMedia, has spent the past 5 years optimizing all of these sensors, and fine-tuning algorithms that take the data to determine actual calorie expenditure. In studies, when comparing calorie expenditure measurements from the armband device to calorie expenditure measurements in a metabolic chamber (the “gold standard” of calorie expenditure measurement), the bodybugg™ armband achieved average accuracy rates of 92%. For more technical information on how the bodybugg™ technology works, please see the techs and specs section.
how accurate are the measurements?
the bodybugg™ device measurements (calories burned, steps taken) have on average shown to be 92 percent accurate (see white papers in the techs and specs section for more information). However, regardless of whether or not you wear the bodybugg™ device, our web interface software will be able to give you your actual average calorie deficit number. This number is derived from your mass change over a week, and since the scale doesn’t lie, neither can the deficit equation. The great benefit of the bodybugg™ device is that by knowing your real calorie expenditure measurements, the web interface can also give you actual number of average calories consumed per day. Instead of having to rely logging every bite you eat, the bodybugg™ system can actually tell you if you ate too much and give you examples on how to cut down. finally – the tools you need to be successful.
