13. Be sure to get enough sleep. It is very important to have a good night sleep if you want to lose weight. If you dont sleep well or if you dont sleep enough, your metabolism will be confused. Also, you are much more likely to overeat if you dont sleep well. So in order to catch up on some dreaming, get up early in the morning, dont drink during the day and dont eat too much in the evening. This way you will be ready for a complete relaxation during the night.
