Dukan Diet website

For starters, I recommend anyone starting or on the diet visit this website. You don't have to buy anything, but definately use the "Calculate my True Weight" tool on the page. This will give you a very reasonable goal weight based on lots of different factors including how many pregnancies you've had, if you smoke and what build you have. It will also give you a realistic timeframe that you can use as a great motivation tool for how long you need to be on each of the four phases of the diet.
