Human beings evolved as the most highly adaptable species on Earth. We have learned to survive and thrive in a wide variety of food environments. Unfortunately, the modern world is triggering changes in our bodies that make us store and hoard fat. It is very difficult to lose weight in fat-storage mode, and even harder to keep it off. Fortunately, we all have an inborn weight-regulating mechanism. But we still must learn and use skills to master our current environment. Evolutionary Eating is a guide for everything you need to know about how to stay fit in our modern fat habitat.
