Human activity sensors report the energy burnt by the user. One of this devices is Freescale's MMA9553L (http://www.freescale.com/files/sensors/doc/ref_manual/MMA9553LSWRM.pdf) that computes the number of calories based on weight and step rate.
Introduce a new channel type ENERGY to export these values.
