Now my problem with weight, has been prevalent for over 30 years, but I am extremely underweight. This book, consequently, is not for me. The vultures out there recognise the massive target audience, of those who need/want to lose weight, but find it impossible. Every other book, is telling us we CAN be successful, just by following a plan. The 2 day diet, has been written by a Doctor (nutritionist) and - I find this quite scary and a tad misleading - an oncologist. To link food to cancer is, imo, a form of emotional blackmail. It may be true but, to use it to sell a book, is just morally wrong. The one way to lose weight, is to consume less calories. Exercise, a quick walk will help. If you do want some advice on which diet is more suitable for you, the internet is a mine of information. And it is free. (apart from the fee you pay for your broadband!)
