The efficacy of morning versus evening exercise for weight loss: A randomized controlled trial

The aim of this study was to investigate the influence of morning versus evening exercise on weight loss, cardiometabolic health, and components of energy balance.A total of 100 inactive adults with overweight or obesity were randomized to morning exercise (AMEx; 06:00-09:00), evening exercise (PMEx; 16:00-19:00), or wait-list control (CON). AMEx and PMEx were prescribed 250 min·wkAMEx and PMEx lost weight during the intervention (mean [SD], AMEx, -2.7 [2.5] kg, p 0.001; PMEx, -3.1 [3.4] kg, p 0.001). V̇OAdults with overweight and obesity experience modest weight loss in response to an exercise program, but there does not appear to be an optimal time to exercise.
