Summary of talk
Few can have missed the memo that obesity is a problem. In the UK, one in five children start school already overweight or obese (rising to around one in three at age 10-11). For young people, overweight and obesity are associated with a number of health-related and psychosocial consequences, both in the short term and the long term. Obese children become obese adults, and the resultant costs to healthcare systems are substantial.

Arguably, obesity is a normal human response to the so-called ‘obesogenic’ or ‘obesity-promoting’ environment in which we find ourselves. Children in most developed countries today are natives of this environment and are thus experiencing the outcome of food systems that are producing increasing quantities of processed, affordable, and effectively marketed food. Children are also particularly important targets for marketers. What does research tell us about how this exposure to unhealthy food advertising has an impact on their diets? And, if we believe it to be impactful, what should we do about it?

The focus of this talk will be on the evidence to demonstrate an effect of food marketing exposure on eating behaviour in children, and will illustrate how this evidence has underpinned policy action in this area (using the UK as an example).

About the presenter
Dr Emma Boyland from the University of Liverpool has published 40 journal articles and 6 book chapters to date, as well as over 30 published conference abstracts. She was recently called as an expert witness for the UK Health Select Committee enquiry into childhood obesity, and she is a member of the Scientific and Technical Advisory Network for World Obesity and a Trustee of the UK Association for the Study of Obesity.

Summary of talk
Adolescent obesity is associated with both short and long term complications including type 2 diabetes, related comorbidities and premature mortality. Lifestyle modification is the first line of treatment. However, which is the best diet remains unclear. Emerging evidence indicates that the primary objective of dietary interventions should be to reduce the total energy intake and the most successful diet will be the one that the patient will adhere. Current recommendations involve moderate daily energy restriction. Yet several studies, including our recent randomised control trial, RESIST, indicate that some young people struggle to benefit from this type of diet. Alternative options are required. We are currently investigating the use of severe energy restriction (very low energy diets; VLED) and an intermittent fasting diet. Preliminary findings from our research and clinical experience with these diets will be presented including our recent findings from ‘SHAKE-IT’, a pilot study using VLED in adolescents with type 2 diabetes.

About the presenter
Sarah Garnett (M Nut Diet, PhD) is a Senior Research Fellow/Dietitian in the Institute of Endocrinology and Diabetes at the Children’s Hospital at Westmead and a conjoint A/Professor, Discipline of Child and Adolescent Health at the CHW Clinical School, University of Sydney. She completed her PhD in 2006, received an NHMRC Australian Clinical Research Fellowship to do her post-doc research between 2007 and 2010 and a Cancer Institute NSW Career Development Fellowship 2011-2013. Her research is primarily focused on developing evidence based interventions for the prevention and treatment of childhood obesity, insulin resistance and type 2 diabetes. In 2015 Sarah took 12 months leave to work in the Child and Maternal Health at the icddr,b in Dhaka Bangladesh where she was able to extend her interest in public health nutrition and epidemiology.

Summary of talk
Since 2010, Dr Kieron Rooney (Discipline of Exercise and Sport Science) and Professor Bob Boakes (School of Psychology) have led a series of experiments in which rats are provided with access to sugar-sweetened drinks. The rats consistently display impairments in cognitive processes dependent on healthy hippocampal function, as well as elevated adiposity, impaired glucose tolerance and fatty livers. This cross-disciplinary work was supported with ARC - Discovery Project funding from 2014 to extend their research into the effects of artificial sweeteners and their consumption on feeding behaviour leading to their current human trial on the behavioural effects of withdrawal from sugar sweetened beverages (ACTRN12615001004550).

This talk will present selected works from this sustained line of research in the rat, that focussed on some of the more popular questions raised in recent years, namely is fructose in beverages more toxic than glucose? Can we recover health by the simple removal of sugar sweetened beverages? And do artificial sweeteners lead to increased food intake and weight gain?

About the presenters
Kieron completed his PhD in the Department of Biochemistry, within the Faculty of Science at the University of Sydney in 2004. Kieron joined the Faculty of Health Sciences in 2003 as a lecturer in exercise physiology and biochemistry and was promoted to Senior Lecturer in 2012. During this time, Kieron’s research portfolio has included both human and small animal studies investigating the role of diet and physical activity on parameters of fuel storage and utilisation.

Bob was awarded his PhD in Psychology by Harvard University in 1967. Following academic positions at the University of Sussex in the UK, he was appointed McCaughey Professor of Psychology at the University of Sydney in 1989 and on retirement in 2005 was awarded the title of Emeritus Professor of Psychology. Retirement has enabled Bob to be a much more productive researcher than when he was a full-time academic. His core research area is in associative learning, but in collaboration with Kieron Bob’s research has increasingly focussed on topics at the intersection of psychology and nutrition.

Summary of talk
It is a common complaint from the general public that nutritionists are always changing their mind about what constitutes good nutrition. One year carbohydrate is good for you and the next year we are told it is poison. Likewise fats that have been labelled bad are proclaimed good. Whilst a critical analysis of dietary recommendations over time indicate that guidance has remained relatively consistent, it is true that advice around some specific nutritional issues has moved. It is commonly assumed that defects in the levels of evidence or its interpretation have been responsible for the production of flawed nutrition advice which has been corrected later when more rigorous assessments have been applied to this data. However, it is quite possible that both the earlier nutrition guidance and the current amended versions are equally correct.

Changes in guidance may not reflect changes in evidence but rather changes over time in human physiology and the environment in which we live. It has long been recognised that interaction with our environment, other lifestyle behaviours and variations in our physiological or genetic makeup influence our nutritional requirements both at an individual and population level. It could be argued that in recent years, the environment in which we live and our state of energy balance (and their interaction) has altered dramatically creating different nutritional demands and altering physiological responses to food and nutrients. Thus nutritional recommendations around nutrients or specific foods such as sugar which may have been appropriate at one time point are no longer valid today.

About the presenter
Tim Gill is currently Professor of Public Health Nutrition at the Boden Institute of Obesity, Nutrition, Exercise & Eating Disorders and Principal Research Fellow within the Prevention Research Collaboration at the School of Public Health. He has wide experience as an academic and within government departments and health agencies. His research interests are in the epidemiology of obesity and improving food environments and public guidance for the prevention and management of obesity both within Australia and the Asia-Pacific region.
