1. A method for analyzing gastric function of a stomach of a subject, comprising:
- coupling a gastrointestinal sensor to a gastrointestinal site of the subject, and sensing a property of the gastrointestinal site using the gastrointestinal sensor;
coupling a set of one or more antral sensors to an antral site of an antrum of the stomach, and sensing a property of the antrum using the set of one or more antral sensors;
analyzing the property of the gastrointestinal tract and the property of the antrum; and
determining, responsive to the analysis, a characteristic of a food ingested by the subject,wherein sensing the property of the gastrointestinal tract comprises sensing a property of a fundus of the stomach,wherein sensing the property of the fundus comprises sensing an electrical current in the fundus, and wherein sensing the property of the antrum comprises sensing an electrical current in the antrum, andwherein sensing the current in the fundus comprises sensing a current indicative of a measure of electrical impedance between two sites of the fundus.

Abstract
Diet evaluation gastric apparatus (18) is provided, which detects when a patient (10) swallows, and detects the type and amount of matter ingested. The apparatus includes electrodes (74, 100) adapted to be coupled to the fundus and antrum of the patient and to measure electrical and mechanical activity therein, and a control unit (90) to analyze such electrical and mechanical activity and optionally apply electrical energy to modify the activity of tissue of the patient.
