Over the decades, more and more neuroprotective functions of ketogenic diets were reported. However, the biochemical mechanisms underlying the magic of ketosis is still being explored by scientists. The author of this book sought to understand the energy metabolism underlying the ketosis process. He and his colleagues applied metabolic imaging techniques and...
