I have met loads of people on the 5:2, yesterday I met a man who had lost 3 and a half stone since Jan on 5:2. He doesn't eat at all on fast days and is going to the gym regularly, but what a fantastic achievement.
I haven't got to the stage where I am choosing healthy options on feast days and do not expect to loose my taste for chocolate (gave it up for Lent, loved it just as much after) but if I can achieve that 1lb I will be happy
