Six out of ten people admit to wanting to lose weight but are bewildered by the number of diets out there, from those that eliminate fats or carbs to those that tout superfoods or fasting days, but all claiming to be the one that will work. This book gathers together 30 of the most popular and talked-about diets from the last 50 years and examines each one in turn, helping the reader to find a diet that is best suited to them and their lifestyle. Each diet is examined in exactly the same way - highlighting its general philosophy and what it promises, how it works and who it's best for - to help the reader make a clear and informed decision.
