Regulation of eating habits
First Claim
1. A method for treating a subject, comprising:
- receiving a sensor signal responsive to the subject eating;
analyzing the sensor signal,wherein receiving the sensor signal comprises sensing, at a gastric site of a stomach of the subject, an electrical potential change generated in association with contraction of muscle of the subject, andwherein analyzing the sensor signal comprises identifying a decrease in a frequency component of the electrical potential as indicative of the subject eating; and
driving a current into tissue of the stomach responsive to analyzing the signal including identifying the decrease in the frequency component.

Abstract
A method for treating a subject is provided, including receiving a sensor signal responsive to the subject eating, analyzing the sensor signal, and driving a current into tissue of the subject responsive to analyzing the signal. The current is typically driven into muscle tissue of the subject'"'"'s stomach (20). Preferably, receiving the sensor signal includes sensing electrical potential change generated responsive to contraction of a muscle such as a stomach muscle of the subject. In a preferred embodiment, the sensor signal is analyzed with respect to the timing of ingestion, and a level of compliance of the subject with a desired ingestion schedule is determined. As appropriate, a parameter of the current driven into the tissue may be configured such that the application of the current to the tissue induces in the subject a sensation of satiation, discomfort, nausea, or vertigo.
