I am another successful Dukaner. I love the Dukan diet. I started in the fall of 2012, lost 55 lbs, gained a bit back, but have been maintaining steadily October 2013. I highly recommend the diet.
Jen is right about the fact that the Dukan thread on this site doesn't get much action. You can go to Go to a forum called "Dukaners" if you want a really active support website. (Do not know if I'm allowed to mention Dukaners on here, but it's so active and supportive I thought I'd let you know.
Good luck!
