Go for it girls. I signed up last year just before christmas (to start round 1 in Feb) and I lost about 8kg before the program following her books, then another 9 during the program. Have mostly kept it off this year. Signed up again for round 4 but haven't been so good this time around (because I haven't been following it) due to excuses. It is absolutely worth while though- if you follow it- you WILL lose weight and WILL tone up and look and feel awesome inside and out! I learned so so much on it. It isn't just nutrition and exercise, she teaches you so much about your own thought processes etc.
