A good part of your unwanted weight is not made up of fat. Rather, it is made up of stored water.
The body stores water when it thinks you are facing a water shortage, and this happens when you don't drink enough water for your body's needs.
To get rid of your water weight, you need to convince your body that water is not in short supply for you. You do that by drinking a lot of water – at least 8-ounce glasses of water every day. You will start seeing a difference in your weight as early as the following morning.
Drinking lots of water also helps you prevent two things: overeating and cravings. Drinking a glass or two of water before every meal will get you eating less food than you expected to. The water you drank will take up space in your stomach and thus signal to your brain that you are full much earlier.
As for cravings, the signal the brain sends for hunger and for thirst is the same. Sometimes your body tells you that you are hungry when what you really are is thirsty.
So, if you feel like you're craving for something, try drinking a glass or two of water. If the craving goes away, then your body was thirsty and just needed some water.
