I'm pretty new to dieting, but after running wild with food in my teens and twenties I'm now paying the price in my thirties and while I never used to put any weight on, now things have got out of control. I want to take it in hand, but I just don't know where to start - there are so many diets and programmes and each one seems to make out that it gives the best results and enables you to keep it off. How did you decide what to follow? Do different diets suit different types of people, or lifestyles? Where do I start?!
