Compared with the evening, the exercise efficiency is lower, especially before going to bed, and the body will be too excited to sleep. In addition, you can't take a shower or eat immediately after exercise. It usually takes 30-60 minutes. You can't drink more water.
If you want to lose weight, you'd better make a good schedule. If the biological clock is regular, it will help to lose weight.
This is some experience that I summarized from my recent crazy weight loss information. I hope it will be useful to you. ^^
