Summary
Sugar-sweetened beverage consumption seems to contribute to obesity and diabetes. We aim to test the impact of multi-component intervention including a school-based nutrition education program combining high levels of parental involvement plus a supportive environment to reduce sugar-sweetened beverage consumption and improve healthy eating among Indigenous Australian children and their families living in remote communities.
Long-term Metabolic Effects Of Stress And Antidepressants: A Novel Translational Animal Paradigm Of Drug-induced Obesity

Summary
Do antidepressants contribute to Australia's obesity epidemic? Millions of Australians are treated with antidepressants, which often causes weight gain. Our work shows that even brief exposure to antidepressants exacerbate body weight gain following exposure to chronic stress. This new knowledge represents a significant shift in the understanding of antidepressant-related weight gain. In this project we will study the mechanisms involved in long-term weight gain after exposure to stress and anti ....Do antidepressants contribute to Australia's obesity epidemic?

Our work shows that even brief exposure to antidepressants exacerbate body weight gain following exposure to chronic stress. This new knowledge represents a significant shift in the understanding of antidepressant-related weight gain. In this project we will study the mechanisms involved in long-term weight gain after exposure to stress and antidepressants in an obesogenic environment.Read moreRead less
Improving Weight Loss By Intermittent Use Of Very Low Energy Diet: The TANGO Diet Trial (Temporary Phases Of Accelerated Weight Loss For Noticeably Greater Outcomes)
Funder

Funding Amount
$660,736.00
Summary
Very low energy diet (VLED) is being increasingly used for the treatment of obesity, but the resultant weight loss is usually transient, partly because it induces powerful adaptive responses that inhibit weight loss and promote regain. We have shown that 'taking a break from dieting' for 2 weeks reduces these adaptive responses. In this project we will thus test whether weight loss outcomes with VLED can be improved via intermittent use, where periods on the VLED are alternated with 'breaks'.
Control Of Neuropeptide FF Receptors On Appetite And Energy Homeostasis

Summary
Despite the alarming obesity epidemic, there currently exists no effective long-term treatment for obesity. Neuropeptide FF and its receptor NPFF2R have an emerging role in regulating food intake and body fat stores. Results from this study will show whether NPFF2R plays an important role in regulating appetite, metabolic rate, body weight and fat stores, thus help to identify whether NPFF2R-targeted therapeutics would confer significant benefit for the long-term treatment of obesity.
Serial NT-proBNP Monitoring For Predicting Major Cardiovascular Events In The Dialysis Population

Summary
Dialysis patients have a 50-100 fold increased risk of dying from heart disease caused by abnormal heart muscle structure and function. Current tests are unable to accurately identify patients at the highest risk. A test that accurately detects the early stages of heart injury is urgently needed. The aim of our research is to develop a monitoring guide using regular testing of a heart hormone (NT-proBNP) to identify high-risk dialysis patients early allowing treatment before a serious medical co ....Dialysis patients have a 50-100 fold increased risk of dying from heart disease caused by abnormal heart muscle structure and function. Current tests are unable to accurately identify patients at the highest risk. A test that accurately detects the early stages of heart injury is urgently needed. The aim of our research is to develop a monitoring guide using regular testing of a heart hormone (NT-proBNP) to identify high-risk dialysis patients early allowing treatment before a serious medical complication occurs.Read moreRead less
Long-term Effects Of Very Low Energy Diet Versus Conventional Diet On Adiposity, Lean Body Mass, Muscle Strength And Bone Density In Obese Adults, And Mechanisms Promoting Changes
Funder
National Health and Medical Research Council
Funding Amount
$925,990.00
Summary
Very low energy diets (VLEDs) are increasingly used to treat obesity. Of concern is the fact that VLEDs induce adaptive responses that can inhibit loss of – and promote regain of – fatness (particularly belly fat) while decreasing lean body mass, muscle strength and bone density. This project will therefore determine whether VLEDs could have negative effects on body composition that increase the risk of metabolic disease, sarcopenia or osteoporosis, and if so, what are the mechanisms involved.
Unveiling The Origin Of Munc18-1 And Alpha-synuclein Co-aggregation At Nanoscale

Summary
Our recent work on Munc18-1 mutations leading to a severe form of human early infantile epileptic encephalopathy (EIEE) led us to uncover a critical role for Munc18-1 in controlling the formation of toxic protein aggregates containing ?-Synuclein. Targeting the Munc18-1 ?-Synuclein interaction may have therapeutic values not only for EIEE but also for other neurological diseases characterised by protein aggregations.
Trends And Determinants Of Blood Pressure In Chinese Children And Adolescents During The Recent Obesity Epidemic: A Repeated Cross-sectional Study Over 25 Years

Summary
Over the last 25 years, the prevalence of overweight and obesity increased over 9 times among Chinese children and adolescents. The aims of this project are to assess the trends of blood pressure levels in children during the period of obesity epidemic, and to estimate the effects of obesity and other factors on the trends of blood pressure levels. In this repeated cross-sectional study, we will analyse the data of six surveys collected over a period of 25 years with over 1.4 million participant ....Over the last 25 years, the prevalence of overweight and obesity increased over 9 times among Chinese children and adolescents.

Determinants Of Brown Adipose Tissue Activation - Implication For The Regulation Of Energy Balance And Obesity
Funder

Funding Amount
$617,192.00
Summary
One of the most important recent findings in the biology of obesity has been the revelation that brown adipose tissue (BAT) is present and functional in adult humans. Even more important, the amount of BAT seems to be related to the extent of obesity. The challenge now is to harness the means by which BAT is activated. Understanding the central neural control pathways and the rate limiting steps in the BAT itself will pave the way for new anti-obesity strategies.
Unravelling The Impact Of An Energy-rich Environment On Susceptibility And Resistance To Obesity

Funding Amount
$796,754.00
Summary
Obesity in Australia is at a crisis point. It is clear that energy-rich environments and an individual’s genes leads to excessive weight gain, but what we don’t understand is why some individuals are more prone to this than others. Comprehending this biological regulation is imperative if we are to develop more effective drug or dietary treatments to abate this disease. Thus it is the aim of this grant to dissect the biological/genetic/possible epigenetic perturbations leading to common obesity.
