Our Programs


Our program lasts for 10 weeks and during that time the participants receive a meal plan, exercise program, education and motivation. Within our clinical program participants achieve weight loss between 12-17kg within the 10 weeks (goal of 10% starting body weight) and learn the skills to maintain that loss.
The program isn’t all about type 2 diabetes either. We cater for all weight related issues such as high blood pressure, high cholesterol, PCOS and more.
Local Contribution
Whilst our program is research based and proven to work within community, it does so because we work in with those who understand the local issues and these adjustments are made to the program. Our goal is to have the individual and the community self-manage for the future so it is imperative that they have input into the program. In addition, Ray will contact local food providers and seek a discount for program participants as well as highlight local shopping strategies that bring the cost of fresh foods down. He will also visit local areas where exercise can be completed and shoot videos of specific workouts that can be done at not cost.
Outcomes Targeted
Whilst lowering their HbA1c will be our primary goal, there are a range of other indicators of success:
HbA1c <7% – Research has shown that current programs achieve this in less than 50% of patients. We will aim to achieve this in at least 75% of patients.
Weight loss of >10% initial body weight
Systolic blood pressure <140 and diastolic blood pressure <95
Reduction in medications
Education of patients to enhance self-management

Research Translation and Impact

Across his career, Ray has made significant impact translating research into community programs. These include:

Rapid Loss Program

In 2009 Ray Kelly formulated a meal replacement shake and lifestyle program that would become one of the largest programs in Australia. Rapid Loss was designed as a meal replacement shake for those who wanted to reduce caloric intake dramatically or could be had as a snack between meals for those who wanted to learn how to lose weight with a focus on consuming fresh, unprocessed foods. The shakes were sold in all major outlets (Coles, Woolworths, pharmacy chains, etc) and the program was provided online. The format had the participants working with their GP to provide safe, long term support. Online and phone support were also provided for the participants, with over 30,000 joining the program each year.


Arnott’s Biscuit Factory

Ray Kelly provided a chronic disease program at the Arnott’s biscuit factory in Western Sydney for their day, afternoon and night shifts. Across the program, 53 participants lost a total of 643kg in 10 weeks. At 6 months follow up, the average weight had only increased by 0.6kg. The results were presented at the European Congress on Obesity (Gothenburg, 2016) and the International Congress on Obesity (Vancouver, 2016).


GWS Giants

Ray Kelly provided an online 12-week chronic disease program for 100 fans of the GWS Giants AFL club. In total the participants lost 1,612kg. Participants were from Western Sydney and had been previously diagnosed with type 2 diabetes or hypertension.


Indigenous Health

Too Deadly for Diabetes is a lifestyle program provided primarily through Aboriginal medical services in rural and remote NSW. Ray Kelly engages with the local Indigenous community and health care providers to identify obstacles and design strategies. This have proven effective with each location witnessing a major improvement in clinical outcomes. An independent study was completed on the program in Western Sydney where participants achieved an average weight loss of 7.5kg and a reduction in HbA1c of 1.7%.

In particular, the Too Deadly for Diabetes program is provided in many areas where the management of type 2 diabetes is often poor. This leads to an increasing number of patients suffering from complications with their feet, kidneys, eyes and cardiovascular system. As participants often improve their food intake, increase physical activity and reduce HbA1c, the previous issues around the co-morbidities are significantly reduced.

In Ray’s experience, Indigenous communities have unique obstacles to health. By guiding discussions, Ray assists local health staff and community in identifying obstacles and then designing localised strategies. This has led to programs which have resulted in substantial improvements in HbA1c and reductions in medication use within short periods of time.

Engaging with end-users and consumers is an integral part of Ray Kelly’s work and his reputation with this has enabled him to gain the immediate trust of Indigenous communities as the community engagement process at a new location begins. Due to media outlets and past participants sharing stories, Ray Kelly has the trust and respect of Indigenous communities and this provides the foundation for discussions about the research portfolio. 

Currently, Ray Kelly provides research-based training and education to GPs, nurses, and other health professionals working in primary care. He then provides support as they embed these changes within their current treatments. This had led to decreases in blood pressure, HbA1c and the co-morbidities associated with these conditions. Often, patients also see a reduction in medications.
