The obesity therapy can be delivered to the patient for a limited period of time such that the patient stops receiving the obesity therapy prior to a second onset of the patient eating solid food, e.g., the patient beginning a second meal which can trigger a second delivery of the obesity therapy to the patient for a limited period of time."
