Fitness is a Journey

I was reading the back of the Baked Lays bag today and there's a quote from some fitness person (I don't remember). This quote can be used to analyze any diet or weight loss program in about 10 seconds.

"Fitness is a journey, not a destination"

You need to do something that is going to get you fit and keep you fit for the rest of your life. Quick fixes and starvation are really not the answer.
