As we all know, there are 2 ways to lose weight: Increase your activity or decrease your caloric intake. If you can do BOTH of those things, you will accelerate the number of pounds that will SHED off your body in a given period of time. YAY YOU!
A word on calories: Calories are a fancy word for "energy", which we all NEED! Without calories, we wouldn't feel like going out and having fun on those days when we call in sick to work (oops, did I just say that?).
