Design outcomes

Primary

MeasureTime frame
This study is set up as a prospective pilot study and does not aim for therapeutic efficacy. Thus, clinical outcome measures do not apply. Outcome will be evaluated by changes in metabolism and immune profile. The central aim of this study is to assess these fasting-induced changes.
