Zara, I think so but not sure. I haven't read the book yet. Just following her instruction. She's got lots of experience, she's been helping friends for many years and has been successful. I do plan to read it though. Just a note, my friend feels strongly that unless you're able to really stick it out and commit it might be wise to wait till a time that you can. My son is getting married in 6 weeks and she wanted me to wait till after the wedding. But I convinced her that I can commit and focus on myself even while preparations are under way. I'm also already thinking that I'm going to have to be on the diet for more than 2 weeks before starting to introduce new things, but I won't count chickens before they hatch. One day at a time at this point. lots of luck to you.
