2 weeks for most of us. Just a little longer for those with more than 100 lbs to lose but not more than 4 weeks total.

I am now in maintenance and still use all the phases(floating between the phases) to manage my weight. 3 days of phase I is enough for me to get my weight down a couple of pounds.

Yes, the book is a very good idea!! In the mean time, you can find our food lists and meal plan charts at the start of the April check in thread.

Good Luck!
