Wearable: Participants will wear an electrode on the chest for the measurement of the heart rate variability, a sensor for temperature measurement, and a sensor for continuous blood glucose measurement. Food intake will be recorded via pictures. One mixed meal tolerance test will be performed as a reference for further analyses. Females have the option to use a device for intravaginal temperature measurement.
Study summary
The goal of this clinical trial is to clarify the normal response of the body after food intake.
Therefore, participants will wear three wearables for two weeks and document their food intake via an app- and picture-based protocol.

Primary outcome measure(s)
Electrocardiogram — 2 weeks Changes in heart rate variability in response to food intake. Assessed through Vivalink ECG wearable that measures a continuous 3-channel ECG.
Body temperature — 2 weeks Changes in body temperature in response to food intake. Vivalink ECG and CORE sensor continuously measure the skin temperature. CORE sensor is also able to determine the body core temperature via a heat flux sensor. For women, body core temperature can be measured with the trackle wearable.
Skin conductance — 2 weeks Changes in skin conductance in response to food intake. CardioWatch wearable continuously measures the skin conductance
Glucose level — 2 weeks Changes in glucose levels in the interstitium in response to food intake. FreeStyle libre sensors continuously measure the glucose levels.
