Investigation Into the Effects of Blood Glucose Levels Upon Eating Behavior in Lean and Obese Non-diabetic and Diabetic Subjects

The CGMS consists of 3 parts: sensor, transmitter and monitor. The small sensor measures the glucose levels from the interstitial tissue. The transmitter is attached on top of the sensor and connects wirelessly to the monitor. The sensor is sterile and comes in an unopened package. It has a plastic wire-like tip that is placed under the skin and continuously measures the glucose levels. One of the study physicians will insert the CGMS wire-like tip under the volunteer's skin with the use of the DEXCOM sensor insertion kit. The transmitter is snapped to the sensor pod and the sensor/transmitter unit will be attached to the skin with an adhesive patch. The monitor is the size of a small hand-held device with a digital screen that displays a graph showing the glucose levels from the previous 4-24 hours.

The Food Record will ask about amount and type of food consumed throughout the day. The participants will also register how hungry they are before the meal and how full they feel after they ate, and type and duration of physical activity
