Faddy diets NEVER work. I don't know this one, but too much liquid will dehydrate you in the end. Sounds stupid, but it's true. You are better losing as little as possible. 1lb per week is ideal. Losing weight too quickly starves the body of sugars, then when you come off the diet, your body craves the missing sugars and you put more weight on. I lost 2 stone that I put on due to medication using Rosemary Conley's hip & thigh. There's an exercise regime with it, so no expensive gyms. There is also plenty to eat. Choice of breakfasts, lunches and a 3 course dinner, if wanted. Fads are always just that, fads. Someone, somewhere is making money out of miserable people!
