What are the advantages and disadvantages of exercising in the morning?

The advantage of morning exercise is that it can produce the biggest and most effective fat-reducing effect when the blood sugar in the body is at the lowest point, and the efficiency is about three times that of around 4 pm, so I suggest that friends who need to lose fat are better in the morning. As for the disadvantages, it is obvious that the blood sugar of the body is at the lowest point in the whole day in the morning, so we should pay attention to the intensity control when exercising. Otherwise, it may cause nausea or even fainting due to blood sugar. Therefore, the suitable exercise in the morning is basically some aerobic exercise with relatively low density, such as swimming or running at a constant speed. The best time for early exercise is after sunrise, because photosynthesis can produce enough oxygen to support your lungs. You can drink a proper amount of water before exercise to avoid consumption during sleep, and you can also eat a small amount of fat and protein to support consumption during exercise.
