Fats vs Carbs

Do you know how people can shed like ten pounds in two weeks? They are not actually shedding fat, but rather are shedding water weight.

Let's say someone decides to eat less carbohydrates and sugars for two weeks. If you studied Biochemistry, you'll know that carbs retain more water than fats. So, if you consume less carbs, you retain less water, and therefore your weight goes down. Fats don't retain as much water as carbs.

This is also why fats are such good energy storages. They store energy and prevent you from getting bloated from water.
