Primary outcomePrimary: Change in Venous Plasma Beta-hydroxybutyrate (BHB) From Baseline to Peak During Acute Ketosis Exposure — 3.5; 0.04 mmol/l

Summary

This study aims to address two key aspects. First, the suitability of selecting a specific sampling site for BHB measurement in patients and research, as well as potential differences between capillary and venous blood measurements. Additionally, the study will investigate the effects of ketosis on EPO concentrations, sex hormone levels, hemodynamic markers, and blood pressure. This investigation will utilize blood samples collected from baseline and at Day 15, between which participants are exposed to intermittent ketosis or placebo in a randomized parallel design.
