Case Study: Successful Weight Reduction and Improved Metabolic Health in a 65-Year-Old Female with Multiple Comorbidities

Patient Background

Mary, a 65-year-old female, had struggled with weight management for most of her adult life. Despite numerous attempts at various diets and weight loss programs, she had been unsuccessful in achieving sustainable weight loss. Mary’s medical history was complex, including Type 2 Diabetes, Osteoarthritis, Hypertension, Gastroesophageal Reflux Disease (GORD), and elevated cholesterol levels. These comorbidities not only impacted her physical health but also contributed to her overall sense of well-being and quality of life.

Introduction to Dietitian Intervention

Frustrated by her previous unsuccessful attempts at weight loss and concerned about the impact of her health conditions on her long-term prognosis, Mary sought the expertise of a dietitian specialising in metabolic health and weight management and made an appointment with me at our Noosa clinic in February 2024. Recognising the need for a comprehensive approach tailored to Mary’s unique needs and medical history, I first conducted a thorough assessment of her dietary habits, lifestyle factors, and medical conditions.

Development of a Personalised Plan

Based on the assessment findings, I was able to develop a personalised dietary and exercise plan aimed at promoting sustainable weight loss and improving Mary’s overall health outcomes. The plan emphasised high-protein, well-balanced meals with an emphasis on vegetables, whole grains, and lean sources of protein. Portion control and mindful eating strategies were also incorporated to help Mary develop a healthier relationship with food and prevent overeating. In addition we also implemented strategies aimed improving her gut and metabolic health.

In addition to dietary modifications, the plan included setting goals around commencing gentle exercise tailored to Mary’s physical abilities and limitations due to osteoarthritis. Mary joined an active adults strength exercise class that focused on low-impact activities such as resistance band exercises, gentle yoga, and walking, aiming to improve muscle strength, flexibility, and overall functional capacity.

Weight LossProgress Monitoring and Support

Mary received ongoing support and guidance from me throughout the 12-week intervention period. Regular monitoring of her weight, waist circumference, blood glucose levels, blood pressure, and lipid profile allowed for objective assessment of her progress and adjustment of the intervention as needed. I also provided Mary with practical tips, food product recommendations, meal plans, and recipes to facilitate adherence to her dietary and exercise regimen.


At the end of the 12-week intervention period, Mary achieved significant improvements in her weight and waist circumference, as well as notable enhancements in her overall health parameters. She successfully reduced her weight by 9.3 kilograms and her waist circumference by 25 centimetres, exceeding the initial treatment goals! Most pleasingly Mary reported that it didn’t feel like she was on a restrictive diet – unlike approaches she had taken before. She described how she had completely changed the way she thought about food and nutrition and felt that her new dietary pattern was sustainable and lifelong. Especially because she was no longer hungry all day long!

Moreover, Mary experienced significant improvements in her glycaemic control, blood pressure, lipid profile, and GORD symptoms – no more Gaviscon before bed!  She also reported feeling more energetic, motivated, and confident in her ability to maintain her healthier lifestyle habits long-term.

Mary’s successful weight reduction and health improvements demonstrate the effectiveness of a comprehensive, personalised approach to weight management in individuals with multiple comorbidities. By addressing her dietary habits, lifestyle factors, and medical conditions holistically, Mary was able to achieve sustainable weight loss and improve her overall health outcomes. This case highlights the pivotal role of specialist dietitians in providing tailored dietary and lifestyle interventions to optimise health outcomes in individuals with complex medical histories.
