"He who does not rise early with the sun does not enjoy the day"

Council of Don Quijote to Sancho


One of the evasive ones with which intelligence protects from the omen of death is indifference. Life is lived as if it were not with one, as if there had been no one before and no one will exist after. It is true that wills are made and the last wills are dictated, but it is more routine than conviction. If you can be sure of something, it is that the contract will never be denounced by the principal signer. That displeasure towards the transcendent brings advantages and disadvantages, while releasing chains. It is well to ignore the earthly condition of the human organism, as long as certain thermodynamic principles are respected. As it turns out, the pandemic that threatens to ruin the species is obesity (more energy is consumed than is needed) and this worries more than one billion people worldwide who would rather be able to combine sedentary lifestyle and health, extremes that They are far from being compatible. In spite of the interest that this problem arouses in developed societies, there is a similar number of people trapped in the opposite (they consume less than they spend), without there being any way to transfer what is left over where it is missing.

Among the things that are forgotten or that are simply unknown are the fact that today's man comes from an animal that has evolved for several million years in the wild, subordinated to cycles of light and darkness. Human physiology is conditioned by these two circumstances: I) animals designed for physical activity become sedentary in a very short period of time and II) man, like his ancestors, lives subject to periods of light (activity), followed by periods of darkness (rest).

The title of this book “LA DIETA DEL TIGRE”, suggests that man, as a domesticated animal that has not yet adapted his physiology to sedentary life, is governed by the biological clock that determines that many animals (among which it is possible to find the tiger) feel the need to go hunting when aiming the first lights of the day, naturally on an empty stomach, and under the stimulation of cortisol which is the hormone that functions as an alarm clock in daytime mammals. The rest are explanations that try to transfer from scientific jargon to plain language some topics of interest, such as muscle diversity, different types of fat, metabolism or antioxidants and answer the questions that lead the chapters. Professional deformation may lead me to the repetition of concepts that I consider difficult for those unfamiliar in biochemistry. Although what would proceed in such cases is to clarify instead of insisting, the recidivism that is aggravating in the crimes should be mitigating for the one who intends to be understood and thus I hope it will be taken.


SALVADOR PERAN MESA is Professor of Physiology and Biochemistry of the Faculty of Medicine of the University of Malaga. He is credited with being the first protocolizer, and therefore the introducer, of the Heel Test in clinical practice in Spain, which is routinely followed today in all hospitals in the country, which makes him worthy of our recognition.

He is a prolific and committed writer, author of numerous books and writings related, beyond his specialty, to social life.
