1. A method comprising:

  • providing a fundic impedance signal of a subject sensed during an initial calibration period using at least one implantable fundic sensor of an eating detection device;

    receiving an indication of actual ingestion events of the subject during the initial calibration period;

    using a cost function, performing an analysis of the fundic impedance signal and the actual ingestion events;

    responsively to the analysis, setting a threshold, the crossing of which by the fundic impedance signal is indicative of ingestion; and

    storing the threshold in a memory of the eating detection device.
