Physical Inactivity and Appetite Regulation

The goal of this parallel-group, two-arm, assessor-blinded, randomised clinical trial is to investigate the effects of reducing physical activity on food intake and satiety in physically active and healthy males, 40-55 years of age. The main questions it aims to answer are: * Does physical inactivity affect GLP-1 stimulated food intake? * Does physical inactivity affect food preferences, satiety and other mechanisms supporting appetite regulation? Participants will be randomised (1:1) to two weeks of either no intervention (control group) or inactivity. Inactivity will be implemented as cessation of active commuting and all other structured exercise. Furthermore, steps will be reduced to a maximum of 1500 steps/day. Researchers will compare the inactivity group to the control group to see if physical inactivity impairs appetite regulation.
