In Fiber Fueled, Dr. Will Bulsiewicz, a renowned gastroenterologist, argues against restrictive diets like paleo and keto, claiming they harm gut health by depriving the body of necessary dietary fiber. He explains that the gut microbiome is crucial for metabolism, hormone balance, and inflammation control. Modern research shows that fiber, particularly from a diverse range of plants, fuels gut microbes to produce beneficial postbiotics, such as short-chain fatty acids (SCFAs), which have numerous health benefits, including weight loss, immune system support, improved brain function, and even cancer prevention. Dr. B emphasizes that a fiber-rich diet, including fruits, vegetables, whole grains, seeds, nuts, and legumes, is vital for long-term health. The book also includes a 28-day program with menus and recipes to help readers begin their journey toward better gut health and overall wellness.
