Conditions

Basal metabolic rate and the influencing factors

Interventions

Group 1: The basal metabolic rate of 40 subjects is measured by indirect calorimetry at different time points. In the first study part the basal metabolic rate is measured twice to determine the time

Design outcomes

Secondary

MeasureTime frame
Secondary outcome of the study are the analysis of factors which might influence the basal metabolic rate. Therefore factors like bloodparameters, microbiota, body composition, physical activity and nutritional habits are analysed. Blood parameters are determined by blood samples. Microbiota is determined by sequencing a stool sample. The body composition is deternined by using a bioimpedanz analysis. Nutritional habits are record by nutritional protocols and the physical activity is measured by an actigraph and heart sensor.

Primary

MeasureTime frame
Which impact has the fasting state, the time point of the measurement and the daily variability on the basal metabolic rate? The basal metabolic rate is measured by indirect calorimetry either at 8 am, 10 am oder 2pm.
