Absolutely...so while you wait for the book to arrive...I'm going to give you a few details to get you started:

No white food -- nothing made from white flour or sugar

Unlimited lean meats, butter, cream and non-starchy veggies. No aged cheese - but cream cheese, parmesan, etc. okay

I will assume for the moment that you are sedentary (could be wrong!) the rule would be:
15 g carb (from fibre rich foods, fruit or starchy veg) per meal, 7.5 per snack. If you are active you can double these amounts.

Eat something from each of the following groups at each meal: non-starchy veg, carb (as per guidelines above), protein and fat.

...and do get the book!
