Why do you gain weight?

The body is a very very “efficient” machine. It is very sophisticated and evolved. One of the main things your body is made for is “survival”.

You know, that you need energy to live and do the things that you do. This energy comes from food. The food you eat is converted into energy. When you “feel hungry”, that is the body telling you that you need to take in some food because the body needs some energy.

As you probably know, energy is NOT ONLY required for actually doing things. You need energy to walk, talk, push, pull etc. But, besides that, the body still needs energy even if you are doing nothing! Even if you are just lying down on your bed, the body still needs energy. Why? The body needs this energy to keep the heart pumping, keep all the different organs functioning etc. All these internal processes take up some energy. So whether you do something or do nothing you still need a certain amount of energy each day to stay alive.

Now, as we said earlier, the body is very sophisticated and made for survival! It prepares for a “rainy day” or a situation where you will have nothing to eat. The average adult can survive for a few weeks without any food before he/she has any serious medical problems. This is possible because the body saves any excess energy that is taken in!

Here is the part we are interested in: The excess energy that you take in, is stored in the body in the form of “fat”!

To understand all this properly, you need to understand the concept of “calories”..
