Many diets are unsuccessful, but Roderick Lane's approach aims to target your individual evolutionary type and work in harmony with the body's specific needs. He believes we each belong to one of five body types - hunter gatherer, pioneer, pathfinder, farmer and dancer - each of which governs our physique and has its own dietary requirements. Treating your body to the best nourishment for its type should reward you with the best health. It outlines how to identify your type, and then advises what, when and where to eat and how to adapt for stress and life changes, with a selection of recipes and menus.
