This book teaches you how to be aware of your day to day eating and exercise routines and how to boost your metabolism naturally, without pills, as well as cut down on your calorie intake so that you are not starving yourself. This book is not only filled with common sense tips and a solid diet blueprint for you to follow, but it also talks about some of the mental challenges that face dieters. These are rarely discussed in diet books that concentrate mostly on foods that you cannot have and those that you must eat. While certain foods should be avoided during this diet, this book will also teach you the correct frame of mind that you need when trying to lose 20 pounds in 3 weeks. Losing weight is more than just dieting, it is a mindset.
