1. A method of detecting food or drink intake in a subject, comprising:
- a) placing one or more electrodes in contact with or proximate to the subject'"'"'s lower esophageal sphincter (LES); and
b) identifying food or drink intake by monitoring electrical activity in or proximate to the LES using the one or more electrodes.

20. A method of detecting food or drink intake in a subject, comprising:
-
a) placing one or more electrodes in contact with or proximate to the subject'"'"'s lower esophageal sphincter (LES); and b) identifying food or drink intake by monitoring electrical activity in or proximate to the LES using the one or more electrodes; wherein an increase in the amplitude of LES electrical activity to a value greater than baseline indicates food or drink intake, and a decrease in amplitude from the value greater than baseline to a lower value indicates cessation of food or drink intake.

21. A device for automatically detecting food or drink intake of a subject, comprising:
-
a) one or more electrodes, for monitoring electrical activity of the subject'"'"'s lower esophageal sphincter (LES) or a region proximate to the LES; and b) a pulse generator, for generating electrical signals based on the monitored electrical activity; wherein the device is configured to identify food or drink intake by monitoring electrical activity of the LES or the region proximate to the LES using the one or more electrodes. - View Dependent Claims (22, 23, 24, 25)

26. A system for automatically detecting food or drink intake of a subject, comprising
a) one or more electrodes, for monitoring electrical activity of the subject'"'"'s lower esophageal sphincter (LES) or a region proximate to the LES; -
b) a pulse generator, for generating electrical signals relating to the monitored electrical activity; and c) a computer for interpreting the monitored electrical activity, recording the monitored electrical activity, or both; wherein the device is configured to identify food or drink intake by monitoring electrical activity of the LES or the region proximate to the LES using the one or more electrodes. - View Dependent Claims (27, 28)
