Matt Stone is an independent health researcher and author of more than 10 books on various health-related topics. He launched an independent investigation into health in 2005, and has since been exploring a wide range of health fields - from general physiology and nutrition to areas as diverse and specific as psychoneuroendocrinology. His investigation has yielded many great, practical insights and simple tips on how regular people can make substantial improvements in their health - for the purpose of both improving or eliminating specific health problems and preventing some of the most common ailments in the modern world. Most of his research has drawn him towards metabolic rate and how many basic functions (digestion, reproduction, aging, immunity, inflammation, sleep) perform better when metabolic rate is optimized.
