"This is a timely and useful text. It provides lots of examples and approaches to aid learning, and is written in a style that is very accessible.
" - Dr Ashley Cooper, University of Bristol

"This textbook provides a comprehensive introduction into one of the most challenging health problems for the early part of 21st century - obesity. It presents an overview of the complex circumstances that result in obesity and identifies the critical factors that are contributing to the obesity epidemic - the poor adaption of our body's biological processes to a relative abundance of food and an increasingly sedentary social environment. Each chapter is written in an easily readable style to makes the book extremely attractive to anyone who wishes to learn more about obesity. I recommend the book to all who wish to better understand the causes, the problems and the management of obesity." -
Professor Peter Kopelman, Principal, St Georges, University of London
"Challenging Obesity is a well-written, comprehensive book dealing with an important public health issue. The authors provide a scientific perspective on obesity, addressing a number of different aspects of the topic.
This book is a valuable and important resource for those studying, researching and teaching in the area of nutrition and public health. Of value to those studying the topic of obesity in particular, are the clear definitions, detailed summaries and self assessment questions. I would recommend this book to my students studying on our Energy Regulation and Obesity module.
Although this book is primarily aimed at those studying the health sciences, individuals with a general interest in health and nutrition will also benefit from this book." - Dr Helen Lightowler, Oxford Brookes University
