The Ninja are perhaps the most idealised and least understood warriors of all time. Their reputation for skill, daring and ability are unrivalled in the annals of history, and their methods, techniques and ways are shrouded in mystery and intrigue. What is known is that the Ninja were very much spiritual and agrarian in their existences and this is the root of their strengths that we can learn from. The Ninja Diet is a plan designed to develop physical and mental fortitude, strength and toughness and is based on sensible and balanced eating coupled with lessons, legends and techniques from the past. The purpose of this book is to assist every day people to develop a 'lean-ness' of body and mind. To develop a sense of inner calm and physical strength, along with an indefatigable psychology and spirit - and not simply become thin. The intention of this book is that the reader incorporates one of the nine lessons into their lives every day, and follows one of the nine lessons, every day. The reader, practice and perform one Kuji-In every day. The reader contemplate and internalise one Haiku every day. The reader consider one legend every day. The reader prepare and eat one meal from this book additional to their regular eating patterns every day. The sharp eyed reader will notice a natural emphasis on both Paleo and Ketogenic diets within the Japanese diet, however this maintains a semblance of balance.
