Methods and devices (10) are provided for delivering obesity therapy to a patient. In general the methods and devices allow for onset of a patient eating solid food e.g. the patient beginning a meal to trigger delivery of an obesity therapy to a patient. The obesity therapy can be delivered to a patient for a limited period of time such that the patient stops receiving the obesity therapy prior to a second onset of a patient eating solid food e.g. the patient beginning a second meal which can trigger a second delivery of obesity therapy to the patient for a limited period of time.
