Read 'Mastering The Zone' by Barry Sears, who is the founder of The Zone diet. (this is what it looks like: ) Have a look on ebay though, you can pick them up pretty cheap.

The Zone webpage has a good explanation on how it all works, laid out simply, read all the articles here, they are only short. The book will go into more detail though and also provides you with a bunch of recipes.

CF Issue #21 has an easy to understand explanation of the zone. Also providing a block chart for the most popular foods, which i have personally found extremely helpful.

Eating meals when busy is hard, but it's something you need to get used too if you want results. MRP shakes, or bars are an idea. You can get Zone bars which have a 40/30/30 split, so just down one of them when you can. You can also get bars from other sources which do the same macronutrient split. Otherwise, make your meals in advance, so you don't need to cook all the time.

And if you're running short on recipe ideas, The PM is great
