Isabelle (Bell) Smith is an Accredited Practising Dietitian and Accredited Sports Dietitian with a special interest in optimising performance and health in female athletes — an area where much of the standard sports nutrition guidance was established in male cohorts and applies imperfectly. Her focus is energy availability, training-phase fuelling and race preparation, and the presentations that follow chronic under-fuelling: recurrent bone stress injury, menstrual disturbance and stalled progress despite consistent training.
Bell works with the Sydney Roosters and the Australian Defence Force, and lectures at the University of Newcastle.
Alongside her work in sport, Bell manages the full range of endocrine and metabolic conditions seen at the clinic: type 1 and type 2 diabetes, insulin resistance and prediabetes, weight management including nutrition alongside GLP-1 therapy, Polyendocrine Metabolic Ovarian Syndrome (PMOS, formerly PCOS), osteoporosis and bone health, thyroid conditions, and gastrointestinal conditions affecting nutritional status.
At The Endocrine & Wellbeing Clinic, Bell works alongside three specialist endocrinologists and Accredited Exercise Physiologist Jessica Coombe, so patients can be properly assessed and managed in one place rather than across separate practices.
