As a matter of fact, if you are in lack of sleep, a hormone called cortisol will be secreted. Cortisol is in fact a hormone to control your appetite. It will also help to convert the excess calories in your body and store it in the form of fat. The lack of sleep may also affect your metabolism and it may lead to relatively higher blood sugar levels. In this case your body will produce more insulin than you need, which may in turn lead to obesity.

It is also very important to stress that sleep deprivation may also lead to weight gain because it will affect your daily behavior. If you are in lack of sleep, you may want to eat more sweet or food that is high in fat content. You will probably want to eat more chips, burgers, candies and cakes. This is because you will need more energy when you are in lack of sleep and eating them can help to raise the blood glucose level and this will give you energy. However, the excessive calorie intake will be stored as fat in your body and this will certainly lead to weight gain

You should probably know that exercising is very important in order to help you to burn the excessive calories. However, if you do not have enough sleep, you will feel very exhausted. Of course you will not want to do any exercise if you feel exhausted. You would like to go to sleep rather than go exercising. And as a result, this will make your body store more fat since the excessive calories cannot be burnt.

In fact, most experts will tell you that you will need to have eight hours of sleep every night in in order to give you enough energy for your daily activities.
