You are gonna have so much fun with this! It is much easier to follow a strict diet when you are learning about the nutrition part of fitness & watching to see how you feel after each meal, each day, etc, instead of just starving yourself, feeling deprived, panicking when you get a craving, etc. And once you've gone thru it, you have so much more control over the act of eating - optimally it becomes a balance of foods you eat & enjoy and just a simple refueling for your body. You've heard the saying "Eat to live, not live to eat"? When you can do that for a fit lifestyle, you have learned the key to quality life.
I'll also add that Shadow can give you some great recipes because it does get awfully boring after a while if you are eating your food very plain. I grill just about everything but I'm pretty thin on the condiments & stuff. Mustard, vinegar, pepper, cajun / hot pepper spices, lemon, etc. I also recommend the "South Beach Diet" book because it has some great, very simple recipes in it.
