If you go to the Newbie thread (sticky at the top of the forum), you will find the answers to most of your questions, including the official Ideal protein protocol sheets that tell you what you can have, what is limited and what is off limits.
IP Ultimate List Recipes, FAQ, Newbie Guide, Exercise, and other Important Threads
You will also find information on what products are compatible with Ideal Protein. They are LONG threads but you really need to take the time to read through them, you will find product info, where to buy, and guidelines for nutritional content. Not all protein shakes are OK to have when using Ideal protein - calorie count, fat content, carbs and protein ALL matter so you need to have a good handle on what the guidelines are.

The Ideal protein plan IS highly restrictive - but it does work. It is NOT a diet you can fall in and out of like Weight Watchers, because part of the diet is putting your body in a state of ketosis (when your body actually stops converting sugar for energy and converts fat for energy). Take the time to read the materials, consider whether it's a plan you can commit to AND whether you can commit to it without the accountability of a coach, including set weekly weigh ins.
