You need to eat in order to move, grow, to build and repair tissues, and to keep your body systems working.
When we eat, our bodies convert the calories in the food to a type of energy our cells can use.
To stay in a healthy weight you must take in the same amount of calories each day.
If you eat too much your body will convert the extra calories into body fat.
If you take in fewer calories than needed your body will convert its stored body fat to energy. - causing weight loss
