Drinking enough water throughout the day is necessary to keep your body hydrated and awake. On the other hand, drinking water can also help you avoid some cravings. For example, if you are dying to eat a slice of pizza. Before you go for it, drink a glass of water. Wait a moment and see if you still feel the craving. Maybe you don’t want to eat it anymore because you were feeling thirsty, not hunger. Maybe it will not always work for you, and the craving will be stronger than hydration and your will, but with it working sometimes, it will help you.
