Is A Higher Intake Of Omega-3 Fatty Acids Advantageous For Weight Loss?

Summary
A 12 month dietary trial will be conducted to investigate whether a diet that is high in polyunsaturated fat (particularly long chain omega-3 fats found in fish oil) improves weight loss and metabolism, compared to a standard low fat weight-reducing diet. Other benefits of the diet, such as improvements in blood pressure, blood lipids and glucose, will be investigated. The findings will be used to refine dietary advice for weight loss and to develop food products enriched with fish oil.
Long-term Follow-up Of Children Born Preterm Who Received High Dose DHA: The DINO Trial Follow-up.

Summary
Children born prematurely are more likely to need help at school and to repeat a grade. One of the factors that may be responsible for the poor development of children who were premature may be the lack of an omega-3 fatty acid, called DHA. We have done a study in which feeds of premature infants were supplemented with DHA at a level equivalent to what a baby would recieve in the womb. We now want to see if these children have improved development at school age.
Effect Of Prenatal N-3 Long Chain Polyunsaturated Fatty Acids On Body Mass In Early Childhood

Summary
In Australia more than 1 in 5 four year-olds are now classified as overweight. There is good evidence that omega-3 fats inhibit the early development of fat cells and thereby reduce the later accumulation of excess body fat. This will be the first human trial to examine whether an increased supply of low cost omega 3 fats in pregnancy can reduce fatness and the likelihood of developing type II diabetes in childhood.
Developing Innovative, Effective And Evidence-based Dietary Interventions For Prevention And Treatment Of Child Obesity

Summary
Obesity rates for Australian children continue to rise. Reversing this trend remains a key challenge in establishing a strong foundation early in childhood for a long and healthy life. How to help children and families balance food intake with activity levels in order to achieve and maintain a healthy weight remains unclear. This research program aims to inform best practice about which food patterns and dietary advice are more best in helping families eat well and reverse the obesity epidemic.

Summary
Dietary change is a significant lifestyle factor in managing the epidemics of obesity and diabetes. Uncovering the details of effective dietary change requires accurate user friendly dietary assessment and advice tools. This research will develop state of the art tools for use in research and practice.

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

Due to the growing incidence of obesity within Australia, use of computer technology may be a method of targeting these people by increasing access to dietary services. Currently available dietary software in the Australian context only allows analysis of nutrient information.

Currently available dietary software in the Australian context only allows analysis of nutrient information. Thus when a dietitian sees a patient they must manually translate food intake to nutrient information, a largely time consuming exercise. DietAdvice is a website that was developed for people to enter in their own food intakes. The food information is sent to a dietitian who develops individualised dietary advice for them. A pilot study of the website has already found it to be feasible in the primary healthcare setting. Tested for 12 months the website was used by 224 patients from GP practices in the Illawarra region of NSW. Approximately 73% of patients were overweight and patients with a high BMI were 1.88 times more likely to use the website in the comfort of their home. Further research about the website however was needed. The research to follow on from the pilot study will aim to refine the DietAdvice website, leading towards its commercialisation for dietitians in clinical practice. The research will be broken into 3 phases. Phase 1 will involve a usability test of the website, assessing the underlying algorithms and testing it with dietitians in private practice. Phase 2 will see volunteers using the website on multiple occasions after being given pre-weighed amounts of food to eat. This will determine how reliable and accurate the information is; and phase 3 will evaluate whether the website is cost effective and if it increases accessibility of health services especially in rural areas. By confirming these attributes there will be a sound basis to commercialise the product.Read moreRead less
