There are some moments when your mind may mislead you. That means you shouldn’t eat every time you feel hungry; perhaps your body is dehydrated and you simply need some water. The symptoms of hunger and dehydration are almost the same, so you can easily mix them up. For example, you will lack energy and feel sleepy. That’s why I recommend you to drink a glass of water at first and later you will see whether you are hungry or thirsty. This tactic may be very helpful for you and you’ll save a great number of calories.
