I did it in 2007 and lost 6 stone. Have kept off the weight but no longer low carb to the degree which IPD decrees. Got caught up in the whole Pig 2 twig forum thing and felt part of something bigger than just dropping weight. India Knight contributed many times a day to the internet forum and that was quite exciting at the time. Weight does drop off very quickly if you follow the rules. I found it just got boring and finding creative dishes to cook became monotonous. If you only have a stone to lose, you should be fine and get on very easily with low carbing. You do need to be very strict with yourself and if you have a sweet tooth try hard to eliminate that. happy to provide any other tips/tales etc. Cabbage will become your new best friend.
