Caroline M. Apovian is Co-Director of the Center for Weight Management and Wellness (CWMW) in the Division of Endocrinology, Diabetes, and Hypertension at Brigham and Women’s Hospital, USA, and a professor of medicine at Harvard Medical School.

He is engaged in research on the prevention and treatment of childhood obesity. He has reported five novel obesity-related full-length genes and published more than 100 articles on obesity.

John A. Hawley is Director of the Mary MacKillop Institute for Health Research at the Australian Catholic University, Melbourne, Australia. The primary focus of his laboratory’s research programme is the interaction of exercise training and diet on human health outcomes with an emphasis on primary lifestyle interventions to combat obesity, insulin resistance and type 2 diabetes mellitus.

Dr Shahzeer Karmali is a minimally invasive gastrointestinal and bariatric surgeon based at the Royal Alexandra Hospital in Edmonton, Alberta, Canada.

Ruth Loos is Vice Executive Director and Group Leader at the Novo Nordisk Foundation Center for Basic Metabolic Research, University of Copenhagen, Denmark. Her research focuses on the genetic aetiology of obesity: by identifying genes, she aims to gain insight into the biology that underlies body weight regulation and the mechanisms that link adiposity to its comorbidities. Furthermore, she examines the role of genetic information in identifying subtypes of obesity, in predicting who is at risk of gaining weight, and in tailoring prevention and treatment strategies.

Dr Wilma Waterlander is Assistant Professor at the Amsterdam UMC, University of Amsterdam, The Netherlands. Her main focus of research is the LIKE (Lifestyle Innovations based on youths’ Knowledge and Experience) project, which combines methods from system dynamics and participatory action research to develop an innovative, accessible and sustainable approach to promote healthy habits in 10–14-year-olds in multi-ethnic groups with a lower socioeconomic position in Amsterdam.
