Biggest Loser 30 Day Jump Start

Options
Hello! I am wondering if anyone has tried the 30 Day Jump Start from the Biggest Loser book? Just wanted to know any feedback and about your results. I've done it for one week and lost 5 pounds WITHOUT the exercise. I was just so lazy last week, but am determined to start the exercise part of the program this week. Anyway, looking forward to hearing about how it went for others!

Thanks!
Julie
