Clinical Trial Summary

The aim of this study is to investigate the effect of overnight fasting versus a diurnal fasting (during daily life activities) in females with and without obesity on inflammation, neurotrophins, energy metabolism, mood, food cravings, and appetite sensations.

This study will be an acute fasting intervention.
