First of all Welcome!!
2nd of all....dont join ediets, spend the money on the book instead.
If you want to start today....
Your carb count for the 1st 2 weeks is 20 grams. You can track this very easily on fitday.com.
Limit your cheese to 2 oz a day, pretty much all beef, chicken and fish, but stay away from the proccessed stuff. 2 cups of salad veggies a day. If you find you have more carbs left over....snack on some more veggies.
Thats pretty much it in a nut shell, if Im forgetting something, somone will pop in and add to it.
Drink
LOTS and
LOTS of water!!! min 64 oz! Try to stay away from shakes, bars, and lowcarb bready type things until you have your 2 weeks in.
Check out the recipe section for some great ideas.
K, thats all I can think of

But
Do buy or borrow the book!!
