Preface

On the one hand, humanity is trying to cope with diseases caused by hunger and malnutrition and on the other hand, it is struggling with health problems caused by obesity and overweight. It is known that obesity due to all causes (hormonal, genetic, malnutrition, inactivity) is increasing rapidly in all age groups and genders in all developed and developing countries. It is reported that the health problems caused by being underweight are much less than those caused by obesity and overweight. While obesity-related health problems reduce the person's life expectancy and quality on an individual basis, they also harm the economies of countries on a social basis due to workforce loss and health expenses. Alternatively, underweight status is also observed due to some mental disorders (anorexia nervosa, bulimia, etc.) and lack of access to food and malnutrition. All these situations show the importance of maintaining a normal body weight. Body mass index (BMI), which has been in use around the world for nearly a century, is a practical, accessible, and important tool for monitoring the body's normal weight. Although there are various sensitive devices that can measure body fat with full accuracy, BMI will continue to exist for normal weight monitoring due to its easy applicability. This book contains detailed information about BMI (overweight, normal weight and underweight) and various research studies in the field of medicine. For this reason, it is sure to appeal to readers from all segments of society. We would like to thank the authors for their valuable contributions to our book.
