Περιγραφή
Does eating more carbohydrates, or fats, cause one to put on more weight? Are ketone bodies toxins or vital products that keep us alive during starvation? Does the concept of ‘fat-burning exercise’ hold true? In this game-changing book, Keith Frayn, an international expert in human metabolism and nutrition, dispels common misconceptions about human metabolism, explaining in everyday language the important metabolic processes that underlie all aspects of our daily lives. Illustrated throughout with clear diagrams of metabolic processes, Frayn describes the communication systems that enable our different organs and tissues to cooperate, for instance in providing fuel to our muscles when we exercise, and in preserving our tissues during fasting. He explores the impressive adaptability of human metabolism and discusses the metabolic disorders that can arise when metabolism ‘goes wrong’. For anyone sceptical of information about diet and lifestyle, this concise book guides the reader through what metabolism really involves.
- Outlines just how wide-ranging the science of human metabolism is, correcting the view that ‘human metabolism’ just refers to why someone becomes overweight or lean
- Explains how our metabolism adapts to many different scenarios, such as fasting, feeding and exercise, providing readers with a basis for understanding the internal workings of their own bodies
- Gives for the first time a clear explanation of how different nutrients interact within our tissues, dispelling any belief that individual nutrients can be considered in isolation and helping readers to approach critically the many writings about diet and lifestyle
