Are you trying to lose stubborn fat? Well, I suggest you try morning exercise.

Mouse experiments have shown that morning exercise is more effective than bedtime exercise. Scientists at the Karolinska Institute in Sweden and the University of Copenhagen in Denmark have found that morning exercise consumes more fat than bedtime exercise.

Circadian rhythm is part of the body's biological clock, with a cycle of 24 hours, and many physiological processes in our body change with the circadian rhythm. In order to test the effect of circadian rhythm on human fat metabolism, the researchers asked two groups of mice to do intensive exercise in the early stages of active metabolic activity and in the early stage of slowing down metabolic activity (equivalent to two periods of time after getting up in the morning and before going to bed).

The researchers found that exercise in the morning increased the expression of genes associated with fat decomposition and increased the metabolic rate. This means that not only do the mice burn more fat when they exercise in the morning, but they also burn more calories for the rest of the day.

Although further verification is needed, Professor Juleen Zierath, a biologist at the Karolinska Institute who participated in the study, said: "our results show that morning exercise is more effective than bedtime exercise in boosting metabolism and fat burning. This study may be helpful to people who are overweight."

Because the genomes of mice and humans are similar and share many physiological characteristics, the study also suggests that morning exercise may be better than bedtime exercise in terms of weight loss, the researchers said. the same conclusion applies to humans. However, some key differences between humans and mice may affect the applicability of the results to humans, such as mice being nocturnal animals. Therefore, further research is needed to determine when exercise is more conducive to weight loss.

"choosing the right time to exercise seems to be important for the body's energy balance and improving the effectiveness of exercise," Zieras said. but more research is needed to verify this. "
