Obesity In The Elderly: Impact Of Weight Loss Therapy On Physiology And Function.

Funding Amount

Summary
The aim of this study is to assess the safety, tolerability, weight-loss efficacy, change in lean body mass and impact of cognition of three approaches to treat obesity in the elderly. We will compare dietary advice, an energy reduced diet and a very low calorie diet. All three groups will also have an exercise program. This study will be of major assistance in developing management guidelines for obesity in the elderly, which will likely be an emerging public health issue.
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)

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'.
Identification Of Microbiome Control Of Weight Loss During Dietary Intervention In Obesity

$644,667.00
Summary
We will develop diagnostic tests that enable prediction of the optimal weight loss diet for patients. Obesity is a growing problem in Australia and weight loss is of proven health benefit. Dieting is capable of delivering useful weight loss but long term success rates are poor. The variable success rates are linked to differences in gut microbiota. Diagnostic tests based on the gut microbiota in stool samples will allow identification of the optimal weight loss diet for individuals.
The Alternate Day Fasting Diet In Adolescents With Obesity: A Randomised Controlled Trial

Funding Amount
$1,007,545.00
Summary
One in four Australian adolescents is overweight or obese. While short-term weight loss is possible, keeping the weight off long term is difficult. We will test whether the alternate day fasting diet is effective, safe and acceptable to adolescents. We will undertake a trial involving adolescents aged 13-17 years who are affected by obesity: they will be randomised to receive either the alternate day fasting diet, or a standard weight control diet.
Improving Successful Long-term Weight Loss By Deactivating The Human Famine Reaction

Funding Amount
$799,102.00
Summary
There are more than 7 million overweight or obese adults in Australia. With conventional methods of weight loss, only 5% of these people will be able to achieve permanent weight reduction of any significance to health outcomes. This project aims to develop more effective and permanent methods of weight management through comparing effectiveness of continuous versus intermittent dieting; and determining what metabolic, hormonal and behavioural factors predict weight regain.
Improving Weight Loss Outcomes By Minimizing Adaptive Responses To Energy Restriction

Summary
While losing excess weight reduces the risk of lifestyle diseases such as diabetes, current weight loss strategies are ineffective for most, in part because the body mounts a ‘famine reaction’ that increases hunger, decreases metabolic rate and may also cause loss of muscle and bone mass. This research aims to determine the effects of the famine reaction on body composition, as well as to identify new ways to block the famine reaction with food, thereby enabling more people to attain and maintai ....While losing excess weight reduces the risk of lifestyle diseases such as diabetes, current weight loss strategies are ineffective for most, in part because the body mounts a ‘famine reaction’ that increases hunger, decreases metabolic rate and may also cause loss of muscle and bone mass.

I am a medical practitioner - clinical research scientist investigating the broad range of health issues related to obesity, especially severe obesity. My studies have largely focussed on learning more about these clinical conditions, their relationship to obesity, examining the effect of substantial sustained weight loss, and translating into practice via educational activities.
Discovering Optimal Weight Loss Interventions To Prevent Osteoarthritis In Obesity Through The Lens Of Early Biomarkers: The TANGO Diet Trial
Funder

Funding Amount
$318,768.00
Summary
Osteoarthritis (OA) is the most common type of arthritis, and an obese population increases the disease burden of OA. Weight-loss is the first line management for symptom relief but is unclear whether weight loss can prevent OA changes in the joint. Biological OA markers can pick up early disease changes long before any signs on routine X-ray. My research will look at the effect of weight loss by very low energy diet on early OA biomarker in patients with overweight or obesity.
Mechanisms Underlying The Efficacy Of Bariatric Surgery – Insights From Rat Models Of Sleeve Gastrectomy And The Adjustable Gastric Band

Funding Amount
$868,472.00
Summary
Bariatric surgery is the only effective treatment for morbid obesity. In order to better understand the mechanistic bases of two such procedures, the adjustable gastric band and sleeve gastrectomy, we have developed rodent models. Here we use these models to better understand the physiology and pathophysiology of these surgeries and extend these findings to inform part of a RCT aimed at identifying the basis for effective joint surgical and medicinal treatments of obesity.
