The human being has developed over the last centuries some eating habits that distance themselves from their true nature. Primitive humans spent much of the day resting and hunting, and their physiology allowed them to cut daily meals down to one or two. At a physiological level, eating fewer times a day and at a defined interval, between 8 and 10 hours, allows the body to learn to draw on its body fat reserves for energy, in addition to giving hours of rest to the digestive and immune system, improving our defenses and helping cells to regenerate. This guide simply summarizes how to practice intermittent fasting in a healthy way. Followed by important elite athletes, the method has demonstrated, at a scientific level, the improvement in the health conditions of people who adopt this new way of eating, in addition to managing to regulate body weight and enhance the body's capabilities.
