As we previously mentioned, water retention does affect the number on your scale, but it can also be a sign that you should make other lifestyle changes. You definitely need to start drinking more water because it will help you feel more energized, improve your quality of sleep and will help you with your weight. Moreover, eating more vegetables and fruits along with drinking a lot of water will help your body function properly, so that it doesn’t need to hold onto excess water. Make sure you drink at least 8 glasses a day.
