30. Drink enough water
When the topic is how one can avoid retaining water, it might seem like a wild notion to ask them if they are drinking enough water. Surely if your body is holding too much water, then you should lay off drinking the same thing that is causing the problem? Not only is this thinking wrong, but it could be damaging to your health.
The reason for this is that your body is a lot smarter than you think it is and it is working day and night to stay alive. When it comes to water, if you are consistently not drinking enough water then your body will respond by holding onto the water that it has. It knows that it cannot survive without water, so it will be damned if it is going to let go of the precious fluid that comes trickling through the digestive tract.
