1. A cardiac rhythm management device, comprising:
- a physiological sensor producing electrical signals associated with a patient'"'"'s physical activity;
a posture sensor producing electrical signals associated with the patient'"'"'s posture; and
a controller coupled to the physiological sensor and the posture sensor, the controller calculating an estimated caloric expenditure based on the electrical signals from the physiological sensor and the electrical signals from the posture sensor.

Abstract
Systems and methods for estimating caloric expenditure. The systems can include a physiological sensor to measure a patient'"'"'s physical activity, and a posture sensor to measure the patient'"'"'s posture. An estimated caloric expenditure can be calculated based on data from the physiological sensor and the posture sensor. For example, the estimated caloric expenditure can be calculated at least in part based on the posture data. For example, the estimated caloric expenditure can be validated based on the posture data.
