A collection of devices intended to help reduce oral caloric intake for a patient undergoing a weight loss program. It includes a custom-made oral intake restrictor with integrated microsensor designed to reduce the oral capacity for food and to measure/record the usage of the device to provide data to enable the patient or their healthcare provider monitor progress on-line, and a microsensor reader. This kit is intended for single-patient use only (i.e., the patient from whom the palate impression was taken for the customization of the oral intake restrictor) and contains reusable devices.
