Summary
Obesity is an increasing problem in the community and is associated with an increased incidence of high blood pressure, high cholesterol and triglycerides, diabetes, heart disease and cancer. Although conventional dietary advice for weight loss is a low fat high carbohydrate and high fibre diet there is a very strong interest in the media and the general population in alternative diets that feature reduced carbohydrate with the remainder of the diet either protein or a mixture of protein and fat ....Obesity is an increasing problem in the community and is associated with an increased incidence of high blood pressure, high cholesterol and triglycerides, diabetes, heart disease and cancer. Although conventional dietary advice for weight loss is a low fat high carbohydrate and high fibre diet there is a very strong interest in the media and the general population in alternative diets that feature reduced carbohydrate with the remainder of the diet either protein or a mixture of protein and fat. Unfortunately there is very little published data to guide the decisions of health professionals in this area and there is a strong demand for such information. We plan to perform 2 large weight loss studies which focus on high protein diets with one exchanging protein for carbohydrate and keeping fat constant and the second exchanging protein for fat keeping carbohydrate constant. We will assess whether the high protein diets blunt the decrease in metabolic rate that occurs with weight loss, and whether it spares some of the inevitable loss of muscle mass. We will also measure whether high protein diets improve glucose metabolism in people already at risk of diabetes and heart disease because of their obesity and high insulin levels.Read moreRead less
Gastrointestinal Function And Appetite In Obesity - Acute And Longer-term Effects Of Changes In Energy Intake

Summary
The prevalence of obesity is assuming epidemic proportions. While weight loss diets help people to lose weight, body weight stabilises over time despite continued dieting. Our research proposal represents a novel initiative with the aim to understand the adaptations in gastrointestinal mechanisms in response to acute and longer-term dietary restriction that compromise weight loss. Ultimately our research will help to develop weight loss strategies that are successful in the long-term.
Weight Loss Programs And Subsequent Fertility Rates In An In Vitro Fertilisation (IVF) Program

Funding Amount
$28,067.00
Summary
Compared with normal weight women, obese women have lower fertility both in natural and IVF cycles. Obesity is a risk factor for many maternal and fetal morbidities. This study will be the first randomised controlled trial aimed at demonstrating the effect on pregnancy rates of a prior weight loss program for obese women undertaking IVF treatment. A 12 week weight loss program including dietary, exercise, education and psychological factors will be initiated in the treatment arm.
Effects Of The Fatty Acid, Lauric Acid, On Energy Intake And Gut Motor And Hormonal Function In Health And Obesity

Summary
Obesity is largely due to energy intake exceeding energy expenditure, thus, strategies that reduce energy intake will result in weight loss. We discovered recently that the fatty acid, lauric acid, markedly reduces energy intake. Our studies will determine the effects of lauric acid on energy intake and body weight reduction in obese subjects. The research is a new initiative and explores the potential of lauric acid as a novel, nutrient-based and side-effect free approach to obesity management.
Australians eat far more salt than is good for their health and the need to reduce salt is well recognized. This project brings together government, industry and scientists in a new, nationwide initiative to reduce the amount of salt eaten by Australians. The project will measure levels of salt in the diet, identify the main foods it comes from and put in place a comprehensive plan to reduce it. Effectiveness will be closely monitored through repeat surveys done over five years
An Investigation Of Physiological Adapatations Contributing To Weight Regain After Weight Loss

Summary
Why we gain weight, and why it s hard to maintain weight loss, is the focus of this study. We can regulate food intake by voluntary control in the short term ( dieting ), but our long term ability to control food intake is more complex. Many proteins work together to regulate food intake, as do circulating factors in our blood. Before and after weight loss, subjects feelings of hunger and satiety will be examined so that we can identify pathways that are involved in successful weight loss.
