Mireille’s Secret Recipe: Magical Leek Soup. A tried-and-tested method to regain your equilibrium. Mireille Guiliano states in her book, French Women Don’t Get Fat: “ Leeks are a mild diuretic, and 48 hours or so of leek soup would provide immediate results to jump-start the recasting. For me, it was the start of a lifelong commitment to wellness as well as the beginning of my appreciation, my love, of leeks, about which there is much more to say. It is a trick I still use from time to time; do try it the first weekend.”“It’s a pretty basic regimen: The juice is to be drunk (reheated or room temperature to taste) every 2-3 hours, a cup at a time. This will be your nourishment for both days, until Sunday dinner, when you can have a small piece of meat or fish (4 – 6oz.–don’t lose that scale yet!), with two vegetables, steamed with a bit of butter or oil, and a piece of fruit.”
