I am interested in the Ideal Protein diet. I need to loose at least 50 lbs by December and don't want to waste my time or money on something that does not work.

Has any one tried this diet? Is anyone currently on it?

There are lots of people who do IP here. Check out the Ideal Protein sub-forum.

Thank you. I have a few other questions. Can I buy items on line? Is it costly?

I don't know -- I personally don't do IP. You should go over to that sub-forum and talk to the people over there.
