Knowing Your Nutritional Level Will Help You:

Determine what you should be doing and why

Understand what’s important to you and what isn’t

Set realistic expectations and match behaviors to them

The best part is: It never has to be complicated.

In fact, most of the time, basics are best.

Unlike in video games, you never have to advance to a higher level.

(Personally, I think that's a bit of a relief. You can get great results... while keeping things simple, relaxed, and easy.)
