A study led by Professor Juleen Zierath at the Karolinska Institutet in Sweden and the University of Copenhagen in Denmark suggests that exercising in the morning may enhance metabolic benefits compared to evening workouts. The research, conducted on mice, found that those who engaged in high-intensity exercise during their early active phase—equivalent to late morning in humans—exhibited increased fat oxidation and improved metabolic outcomes.
The study indicates that the timing of exercise can influence the body’s circadian rhythms, which in turn affects metabolism. While the research was conducted on animals, the findings provide insights that could inform human exercise routines, particularly for individuals aiming to optimize fat burning and metabolic health. Further studies are needed to confirm these effects in humans, but the evidence points toward potential benefits of morning workouts.
