First Claim
1. A method for monitoring health of a living body, the method comprising:
- implanting a plurality of sensors within the body so that the sensors generate signals correlating to energy expenditure of the body, a first set of the signals during a first portion of a time span indicating a first rate of energy expenditure of the body, a second set of the signals during a second portion of the time span indicating a second rate of energy expenditure greater than the first energy expenditure;
calculating an overall caloric energy expenditure of the body for the time span using the signals such that the calculated overall energy expenditure correlates to the first energy expenditure over the first time portion combined with the second energy expenditure over the second time portion; and
at least one of displaying the calculated overall energy expenditure or treating the body in response to the calculated overall energy expenditure.

Abstract
Methods, systems and devices for monitoring the health and energy expenditure of a living body, treating patients with an eating disorder or treating obese patients are described. The methods, systems and devices described may also be applicable to any treatment in which presenting feedback regarding patients'"'"' eating and exercise habits is desired. The present invention provides for treating a patient by collecting ingestion and exercise information about the patient from implanted sensors and communicating the collected information to the patient and/or to their health care provider(s). In some embodiments, stimulation of the patient'"'"'s stomach is also provided to reduce caloric intake.
