This excerpt from the book The Energy Paradox by Steven R. Gundry, MD, focuses on the root causes of fatigue and how to regain energy. Gundry argues that modern lifestyles, from diet to stress, deplete energy levels, leading to a range of health issues. The book highlights the importance of a healthy gut microbiome and its impact on energy production. Gundry proposes a six-week program called "The Energy Paradox Program" that involves dietary changes, including avoiding lectins and incorporating fiber-rich foods, and a timed eating schedule known as "chrono consumption." The program aims to restore the gut microbiome, boost mitochondrial function, and increase metabolic flexibility for greater energy production.
