Metabolism, Diabetes & Obesity
Our researchers are committed to understanding the causes of metabolic disease and obesity, and the links between obesity and other health issues
Metabolic diseases and obesity are emerging as the epidemic of the 21st century, driven by an increasingly sedentary lifestyle and poor dietary habits. The global prevalence of obesity almost doubled between 1980 and 2014 so that now approximately 40% of adults are overweight worldwide and 11-15% are clinically obese. Obesity directly increases "all cause" mortality being a risk factor for a myriad of diseases including stroke, cardiovascular disease, type 2 diabetes (T2D), liver diseases and several cancers. Excess body weight is a major and leading factor in overall disease burden worldwide and increasingly, obesity is now being recognised and treated as a chronic disease.
A key challenge in obesity management is that losing weight and sustaining weight loss is profoundly difficult. Pharmacotherapy as an adjunct to lifestyle intervention (and in some cases, surgical approaches) works better than either alone. Research leading to an improved understanding of the physiology of obesity is crucial for the development of improved treatments that work as well, if not better, than surgery.
According to the International Diabetes Federation, the worldwide prevalence of T2D is 371 million, estimated to rise to 552 million by 2030, closely paralleling the rise in obesity. New treatments based on novel drug classes are also required for better managing metabolic diseases such as T2D and its associated co-morbidities including diabetic neuropathy and cardiovascular-renal diseases.
Academic institutions play an increasingly important role in the development of innovative products for these metabolic diseases and obesity, by providing a fundamental understanding of the mechanisms and pathways underlying their causes, through to discovering new targeted treatment options.
Who we are
Professor Tony Tiganis leads the Metabolism, Diabetes and Obesity program, comprising 11 primary group leaders and their research teams, and 16 affiliated groups from other BDI Discovery Programs. To achieve our goals, we adopt a multidisciplinary approach, working with clinicians, international and national research partners, and industry to ask and address clinically-relevant questions. We use cutting edge biochemical, cell biological, physiological and imaging approaches, and a suite of animal models to support our research.
The goals of the Metabolism, Diabetes and Obesity Discovery Program are to:
- Gain a better understanding of the molecular mechanisms underlying metabolic dysfunction and energy homeostasis, the development of obesity and T2D and the factors influencing disease progression
- Understand the molecular drivers of secondary complications of obesity and T2D, such as cancer and liver diseases
- Identify and validate new targets based on clinically-relevant models of disease for drug discovery and development
- Develop improved pharmacological approaches to combine with other interventions for maintaining weight loss
