Hi I've only been on it for about a month now and I'd say give it a try! I'd not done any proper dieting ever really, and been my +-75 kg size 16 for 20 years (aargh I'm old...), but two kids later there is this padding on my tummy which I thought I'd try to shift just this once! My waistline has already reduced noticeably - at least as far as my clothes are concerned.
The Dukan Diet, when I stumbled across it, looked very simple, and has no complicated counting of calories / points whatever, which seemed a bonus. You're allowed to snack when you want to, and it turns out that you don't get hungry any more so snacking becomes less an issue. I googled and found some people's blogs and accounts and I was convinced to give it a try.
Yes the list of 'attack foods' is quite limited and can get very boring, just dive into our spice rack and remember to eat meat as well as fish, and add 'sauces' made from low-fat fromage frais / quark (and don't forget the egs). But soon you can add veg every second day and suddenly cherry tomatoes are such a treat
I'd recommend buying the book, which whilst occasionally a bit vague on detail, gives you a good explanation of how to start and how to stick with it. It also has some recipes.
Come and join us and good luck!!
