Detaillierte Beschreibung
To evaluate the effect of blood glucose levels on eating behavior in a population of patients with diabetes in a free-living environment; the investigators plan to study lean healthy control subjects (BMI <25 kg/m2) and obese non-diabetic subjects (BMI > 30 kg/m2).
The participants who qualify will be invited to use the CGMS (DEXCOM G4 Platinum) for up to 7 days. On the visit for placement of the CGMS: 1) the participants will be explained by one of the study physicians how to use a glucometer (FreeStyle or Accu-Check), 2) they will have the CGMS inserted under the skin, and 3) they will be instructed how to fill up the food log (informational brochures are available at the end of the protocol. On the second visit (up to 7 days after the initial visit) the CGMS will be removed from the skin and the glucose meter and food log will be returned to the investigators.
When this study was initially designed, it incorporated 2 additional arms in the study: T1DM and obese T2DM patients. These patients were never recruited for the study.

Aktiver Komparator: Lean Healthy Control
(BMI <25 kg/m2)
|
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.
Andere Namen:
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
