Abstract
The invention provides methods and devices to sense food intake, and parameters such as glucose concentration that change as a function of food intake, in a patient. The invention provides for measurement of physiological parameters that change as a function of food intake, such as a core body temperature. Some embodiments of the invention also measure activity of the patient. The invention may further provide methods and devices to provide treatment for medical conditions related to food intake, such as delivery of insulin or other substance to regulate the blood glucose of the patient.
