Dr. Javier Pereyro and Dr. Fernando Sarmiento propose interesting questions. Have you ever wondered why by eating the same thing some people gain weight and others stay thin? Why do most of us sleep at night and are awake during the day? Why do we get hungry at a certain time? Why does the dream appear at night? Why do some of us concentrate more in the morning and others more in the afternoon? Why do miracle diets fail? Why is it that at a certain age everything is more difficult and it costs a lot to lose weight?

This is a very interesting book that the entire public can read, in which it is explained in simple language, with examples and didactic comparisons, many concepts that to this day are not fully clarified, in which the nature and The different moments of the day, related to the light of day and the darkness of the night, mark the rhythm of our lives, all of them issues that Chronobiology studies.

In this work, what we consider to be the 7 General Postulates of Chronobiology, never before described, are stated for the first time. Likewise, this book abounds in examples and comparisons that make aspects of science more understandable for years only reserved for the classrooms and laboratories.

We will address the big questions of Medicine and Health Sciences through hypothetical concepts specially constructed so that everyone, specialists in the subject and ordinary people, understand them clearly. We will try to understand metabolism by comparing its metabolic pathways with the tentacles of an octopus, its complex and mechanized functioning with the three rules of a board game, the phases of Stress with the rungs of a ladder, human physiology with the mechanics of a automobile and the complex tide of hormones with a wonderful symphony orchestra.

Applying these concepts, we will understand how our body works, discovering when is the best time of day to eat, to sleep, to burn the greatest amount of fat without altering muscle mass, the importance of working our muscles in order to prolong our existence and thereby having a healthier and higher quality life. This book will show and guide you into a never-before-known and very interesting terrain that will transform your life.
