FBCx trial: Fibre supplement and Ginseng for weight loss and blood sugar control

Obesity is a serious chronic health issue that can result in debilitating health complications such as Type 2 diabetes mellitus. Identifying effective strategies to reduce the prevalence and severity of both is critical. The FBCx study will investigate two novel supplements, alpha cyclodextrin and Compound K.

Alpha cyclodextrin is a fibre supplement that has the ability to complex with and prevent the absorption of dietary fat more efficiently than other known dietary fibres. This supplement may assist with weight loss. Compound K is a Ginseng derivative that has been shown to have antidiabetic properties and therefore may help to assist with blood glucose control.

2 to 20: The Children’s Cardiovascular Health Study

Help us develop better ways to detect cardiovascular disease early.

The University of Sydney is in the process of developing a simple method to assess central blood pressure in children. Central blood pressure measured in the main blood vessel of the heart more closely predicts risks of developing heart disease than current methods measured in the arm. At current, there is no efficient way to measure this in children.

We are seeking participants between the ages of 2 - 20 years to take part in our study. Participation will involve attending the Clinical Research Facility at the University of Sydney for approximately 2 hours over one day for cardiovascular assessments. You will be reimbursed for your travel expenses and time.

If you would like to participate or would like to enrol your child to participate, please contact us for more information.

Novel Exercise Therapies in Type 2 Diabetes

Type 2 diabetes can result in an array of cardiovascular and metabolic complications and is often seen in people who are overweight or obese. High intensity interval training (HIIT), which involves regular short exercise bouts,has been shown to produce similar benefits to more time-consuming exercise which is currently recommended in public health guidelines. For instance, recent scientific studies have suggested that HIIT can improve fitness, cardiovascular health, and reduce visceral fat with or without weight loss.

This research aims to examine the effect of a novel approach to HIIT training (only 4 minutes of vigorous exercise per exercise session) compared with traditional aerobic exercise guidelines on metabolic and cardiovascular risk outcomes. To be eligible for participation you must be aged between 18-65, have a body mass index (BMI) greater than 30 and not currently undertaking regular exercise. The intervention runs for 12 weeks and requires attendance at the Charles Perkins Centre for 3 days each week. Participants randomised into an exercise group will receive full supervision by an Accredited Exercise Physiologist.

PRE-BABE Study: Preconception weight loss for women above a healthy weight

Preconception health is a critical part of a woman’s health that impacts on her chances to get pregnant and achieve a healthy pregnancy.

1 in 2 women in Australia start their pregnancy journey above a healthy weight. Although you might be healthy, carrying extra weight at the start of a pregnancy can be associated with complications in pregnancy such as hypertension, diabetes, miscarriage and caesarean delivery.

Losing weight before getting pregnant may help you to conceive naturally and is also safer for you and your baby than trying to lose weight during pregnancy.

What does this study involve? This study is a pilot randomised controlled trial which means that you will be randomly allocated to one of two weight loss programs:

1. An online weight loss program

2. Recommended weight loss advice delivered in a clinic setting
Both weight loss programs are safe and are designed to be followed for a duration of 10 weeks, prior to start trying to get pregnant. If you do however happen to get pregnant whilst in the trial, just let us know and we can advise you on a general healthy pregnancy diet.

If you choose to participate in this study, you will be asked to sign the participant consent form and complete some online questionnaires about your general health, lifestyle and medical history. You will also have your weight, height and body composition measured at the start and at the end of the program.

Ethics approval number: HREC/17/RPAH/579

You may be eligible to participate in this study if you are :

  • women with BMI above or equal to 25kg/m2 planning a pregnancy in the next 6 to 12 months

The “Say No” trial: a pragmatic intervention to reduce instances of indulgent energy intake behaviours

** Please note: participants have now been fully recruited for this trial ** We are recruiting for a study, which will investigate three behavioural strategies to help control dietary intake. You may be interested in taking part if you want help to control what you eat. We live in an environment where there are constant cues to eat, and there are times when we eat too much. Identifying strategies to help us navigate this environment may help us with weight management.

To be eligible for the study the following criteria must be met:

  • You must have a BMI of at least 25 kg/m2 (calculate your BMI
  • Would like to reduce the number of indulgent foods and drinks you have
  • Not pregnant or intending to fall pregnant within the study time period (8 weeks)
  • No current eating disorder or medical history of eating disorders
  • Not taking part in a clinical weight loss trial
  • Not attending a weight management program (including pharmacotherapy or bariatric surgery)
  • Not taking weight loss medications and other drugs that may affect body weight e.g. anti-psychotics, anti-depressants, or corticosteroids.

This is an 8-week trial and you will be randomised to one of the three groups. You will be asked to come and see us at the beginning and at the end of the study.

If you are interested in taking part or would like more information please contact the team via email: or by phone: +61 2 8627 1990.

The TEMPO Diet Trial: Type of Energy Manipulation for Promoting optimum metabolic health and body composition in Obesity

** Please note: participants have now been fully recruited for this trial ** For many years health professionals have recommended ‘slow and steady’ weight losses of approximately 0.1 to 1 kilo per week. In recent years however, an increasing number of health professionals are prescribing meal replacement diets called very low calorie diets (VLCDs) because they can induce relatively fast weight losses of approximately 0.5 to 2 kilos per week, which some people find motivating, and because some people report not feeling hungry while following a VLCD.

While VLCDs are known to be safe and effective in the short-term (for up to one year), the long-term consequences are unknown. This study will demonstrate whether or not there is any difference between the effects of weight loss via VLCD or conventional diet on metabolic health, body fat content and distribution, muscle mass and strength, and bone density in post-menopausal women for 3 years after commencement of the diet.

A Novel Probiotic-based Intervention for Adults with Pre-diabetes and Recently Diagnosed with Type 2 Diabetes

** Please note: participants have now been fully recruited for this trial ** Probiotics are live microorganisms which when administered in adequate amounts may confer health benefits to the host and may ameliorate obesity-associated dysbiosis by restoring the balance of the gastrointestinal microbiota and improving metabolic profiles. Probiotic-based intervention could be used to support standard lifestyle advice to control obesity-associated disorders.

We are conducting a clinical trial to investigate the therapeutic effect of a multi-strain probiotic in improving blood sugar levels and lipids and reducing inflammatory markers in obese men and women with known higher glucose levels. We are further examining whether the probiotic changes the gastrointestinal bacteria composition from a disease-prone to a balanced state.

To qualify for participation you must be 18 years or older and have:

  • A BMI greater than or equal to 25 kg/m2
  • Pre-diabetes or being recently diagnosed with type 2 diabetes (within 12 months)

An oral glucose tolerance test will be performed to confirm if you are eligible. To be eligible you must stop taking (4 weeks before starting the trial) dietary supplements such as fish oils, herbal formulas, multivitamins, minerals, probiotics, prebiotics and antibiotics. People with serious disorders, including internal organ disease, inflammatory bowel disease, coeliac disease and also those diagnosed with diabetes for more than 12 months will be excluded.

Those who meet the criteria will be randomised to either the probiotic or placebo groups for 12 weeks duration. Four visits are required at the Boden Institute. Stool samples and blood samples will be required before supplementation and at week 12.

Exercise and liver fat reduction in pre-diabetes: moving beyond weight loss

** Please note: participants have now been fully recruited for this trial ** A fatty liver contributes to the risk of cardiovascular and metabolic disease (including diabetes) and is often seen in people who are overweight. Recent scientific studies have shown that exercise can lower liver fat with or without weight loss. However, there are currently no guidelines for exercise to manage liver fat levels.

This research aims to examine the components of regular exercise which result in a liver benefit by comparing different aerobic and resistance exercise programs on liver fat and cardiovascular risk outcomes. Participants in this trial are aged between 29-59, have a body mass index (BMI) greater than 25 and are not currently undertaking regular exercise.

Arnott's Study: Vita-Weat supplementation on weight loss in an overweight and obese group

** Please note: participants have now been fully recruited for this trial ** Foods high in protein, slowly digested carbohydrate, and/or fibre are relatively more filling than equal-caloric portions of foods rich in fat or rapidly digested carbohydrate. This implies that those trying to lose weight should restrict their intake of less filling foods and should instead base their diet on relatively more filling foods, as a means of controlling their energy intake without needing a severe energy restriction.

The satiety index method was developed in order to rank equal energy portions of different foods by the extent to which they increased the feeling of fullness over a two-hour period. The most satisfying foods were found to be high in carbohydrate or protein, and most were also high in water and fibre. Considering the high carbohydrate (more than 60 grams per 100 grams) and high protein (more than 10 grams per 100 grams) content of the Arnott’s Vita-Weat range, these products may produce greater satiety and hence help produce weight loss for those needing to lose weight.

This study will investigate the degree to which different foods and nutrient formulations can maintain satiety (the feeling of fullness after a meal) in both normal weight and overweight people. If you need help to lose weight, you may be interested in participating in a randomised controlled trial of two different diets. For 6 weeks you will receive weight loss advice from our Dietitians and Exercise Physiologists (at no cost to you).

Participants in this trial are aged between 25 - 55 and have a body mass index (BMI) between 25 and 35 kg/m2. Participants with Type 1 diabetes, Type 2 diabetes on insulin or have celiac disease or gluten intolerance are not eligible. Female participants are pre-menopausal.

HAPIFED Weight Management and Eating Disorder Program

** Please note: participants have now been fully recruited for this trial ** The Universities of Sydney and Western Sydney are conducting a free program for individuals 18 years or older who are overweight and who have a problem with binge eating or bulimia. The program aims to determine which of two treatments may be most effective at helping people to reduced disordered eating and at the same time improve weight management, so that they can lose weight and then maintain this weight loss over the longer-term. The program involves 19 skills-based group treatment sessions over 2 months.

EXSCEL Clinical Trial

** Please note: participants have now been fully recruited for this trial ** Type 2 diabetes is a leading public health issue. The majority of people with type 2 diabetes die as a result of cardiovascular disease (CVD). A number of trials in people with Type 2 diabetes have shown their CVD risk can be reduced by lowering cholesterol, blood pressure and glycated haemoglobin or all 3 risk factors.

The EXSCEL Trial is looking at a medication called Exenatide in reducing the above risk factors and promoting weight loss. Participants must have Type 2 diabetes and a history of cardiovascular disease. The medication is self injected once weekly and participants will be enrolled in the trial between 4-7 years. Appointments at the Institute are twice a year. Participants meet with our expert staff consisting of Endocrinologists, Nurses, Dietitians and Exercise Physiologists to manage their health care throughout the trial.

A novel exercise regime to reduce cardiometabolic risk in overweight sedentary individuals

** Please note: participants have now been fully recruited for this trial ** Regular exercise produces many health and fitness benefits, but the effectiveness of different types of exercise programs is unclear. Current health recommendations for people who are overweight suggest that exercise should be regular, low intensity and prolonged. However there is new evidence that exercise involving either short high intensity bursts of strenuous exercise with regular recovery periods, or stretching/massage and core stability work may produce these benefits in less time.

The aim of this research is to compare the benefits of different types of exercise programs. Participants in this trial are aged between 18-55, have a body mass index (BMI) between 25 and 29.9 and are not currently undertaking regular exercise.
