About this book
Obesity and thinness are contrasting conditions that are too often discussed separately. This book treats them together, setting out their definitions, global prevalence, and health impacts, then examining the causes behind each — genetic predisposition, hormonal imbalance, lifestyle, and psychological factors.
It describes the health consequences of both: cardiovascular complications, metabolic disorders, immune deficiency, and effects on mental health. On the practical side, it covers prevention through eating patterns, physical activity, and public health policy, and reviews treatment across lifestyle modification, medication, surgery, and psychological therapy.
A comparative section analyses risk factors shared by both conditions alongside the causes unique to each, and the book closes with integrated approaches to weight management, case studies, and where research and personalised medicine are heading.

Looking ahead
Case studies, integrated weight management, and the direction of personalised medicine.
Note. This book is health education, not individual medical advice. Weight — in either direction — is best addressed with a clinician who knows your history; medication and surgical options in particular require medical supervision.
