Abstract

Systems, methods and devices to measure and potentially promote thermogenesis, preferably non-exercise activity thermogenesis are disclosed. In the various embodiments, the present invention may rely on one or more sensors that detect a subject'"'"'s body posture and/or activity. Feedback regarding the subject'"'"'s posture and/or activity (relative to preferred postures and/or activity levels) may preferably be provided after the data is retrieved and analyzed. A power interlock may also be used to control delivery of electrical energy based on a subject'"'"'s posture and/or activity level.
