About

What if your struggle with weight, cravings and low energy has never been a lack of willpower? For nearly 30 years, I've cared for patients in some of medicine’s highest-stakes environments. As a Consultant Anaesthesiologist and Fellow of the Australian and New Zealand College of Anaesthetists (FANZCA), I've looked after more than 20,000 patients and seen how obesity, insulin resistance, and metabolic dysfunction affect nearly every aspect of health and recovery. I've watched excess weight turn routine surgery into high-risk surgery. I've seen prediabetes evolve into chronic disease. I've cared for patients whose bodies were working against them long before symptoms became obvious. Then I experienced it myself. At 102 kg, I was prediabetic, fatigued, dealing with joint pain, high cholesterol, and steadily declining energy. That experience changed the way I understand health. By applying the science of nutrition, appetite regulation, muscle, sleep, and metabolic health, I lost 24 kg and restored my health. Today, I help people understand why their body may be resisting change and what they can do to work with their biology instead of fighting it. I share evidence-based insights on: ✓ Obesity and weight regulation ✓ Insulin resistance and prediabetes ✓ Hunger, cravings, and appetite control ✓ Muscle and metabolic health ✓ Sustainable fat loss ✓ Longevity and healthy aging Through The Health Accelerator, my mission is to translate complex medical science into practical strategies that help people improve their health for the long term. Every insight I share is grounded in physiology, clinical experience, and evidence-based medicine. If you're interested in understanding the science behind weight, metabolism and longevity, follow me. The better you understand your biology, the more power you have to change your future.

Experience

  • Founder at The Health Accelerator
    Aug 2025 - Present · 11 mos

    Founded an evidence-based program helping men and women achieve fat loss, reset metabolism, and extend healthspan. Approach integrates clinical insight + lived experience, drawing on my own transformation (24kg fat loss, reversal of pre-diabetes, joint pain, and lethargy). Core principles: when and what to eat, how and when to exercise, and how hormones shape obesity. Mission: cut through misinformation, challenge the outdated “calories in vs calories out” model, and empower people with knowledge and practical strategies for lasting change.
