Jake shares his health journey, the path that led him to becoming an accredited clinical nutritionist, weight loss nutritionist, sports nutritionist, and keynote speaker.
He is not a typical nutritionist. His story is defined by extreme challenge, resilience, and profound transformation. After surviving severe anorexia nervosa and a brain tumour, he did not simply recover. He rebuilt himself from the ground up. He devoted his life to mastering evidence based nutrition and achieving extraordinary health.
His approach is lived, proven, and relentlessly results driven.
Jake first developed severe anorexia nervosa at just 15 years old. Over the next decade, his condition became life threatening. He required 20 hospital admissions and faced the very real possibility of death multiple times. The effects of starvation were not only physical. They permeated every part of his life. He was malnourished, weak, and often unable to function like a normal teenager, while his mind was trapped in cycles of obsession, fear, and anxiety around food.
One of the most extreme episodes occurred after he went without any food for seven days. His heart rate dropped to just 25 beats per minute, a dangerously low level compared to the normal healthy range of 60 to 100. His doctors and nurses feared he would not wake up the next day. They told his family that, given his critically low heart rate, there was a very real chance his heart could stop overnight. That night, lying in a hospital bed, he remembers thinking with absolute clarity, “Jake, you are not going to wake up tomorrow”. He later shared this moment as a closing keynote speaker, reflecting on the terror and certainty he felt in that moment and the raw fragility of life.
Against all odds, Jake did wake up the next day. That survival was not just luck. It marked a turning point that began a deeper understanding of the human body. Experiencing life completely starved of essential nutrients gave him firsthand insight into what happens when the body and mind are malnourished. He felt every physiological consequence including extreme fatigue, brittle hair and nails, disrupted hormonal balance, impaired cognitive function, and a body that struggled to sustain life. He also experienced the psychological impact including anxiety, mood swings, obsessive thoughts, and an overwhelming sense of helplessness. He learned in the harshest way how a lack of proper nutrition can systematically shut down not only physical systems but also the ability to think, feel, and function fully.
This period of his life was not only about survival. It became his education in human biology under extreme conditions. He saw clearly the devastating consequences of depriving the body of high quality nutrition not for a few days or weeks, but every single day, 365 days a year. He learned the importance of macronutrients, micronutrients, vitamins, minerals, hydration, and the timing and quality of food. He witnessed the interconnectedness of mind and body in ways that no textbook could ever teach.
Jake’s journey through anorexia did not end with recovery. After overcoming years of starvation and its profound physical and psychological effects, he faced another monumental challenge. He was diagnosed with a Grade 3 Frontal Lobe Astrocytoma brain tumour. This experience forced him to rebuild not only his nutrition and physical health, but also his neurological function, energy systems, and overall wellbeing. During this period, he discovered the full transformative power of nutrition. He learned that food is not only fuel. It is medicine, a performance enhancer, and a tool for long term prevention. Every meal, every nutrient, and every decision about what he put into his body became an act of self rebuilding, self preservation, and empowerment.
These lived experiences now form the foundation of everything he does as a nutritionist. He understands on a cellular level what it takes to rebuild a body that has been broken down by years of deprivation, illness, and trauma. He knows what it means to reclaim energy, restore optimal function, and rebuild confidence in one’s own body. He uses that knowledge every day to support his clients, whether they are struggling with weight loss, seeking peak athletic performance, or simply trying to feel like themselves again.
Through this journey, he learned a truth that shapes his entire philosophy. Nutrition is far more than calories and macros. It is about restoring the connection between the body and mind, rebuilding from the inside out, and using evidence based strategies to create lasting health. He knows what it feels like to be at rock bottom, and he knows what it feels like to come back stronger, healthier, and more capable than ever. His mission is to guide others along that same path and to give them not only a plan, but the knowledge, mindset, and confidence to thrive every single day.
These experiences taught Jake that true transformation does not happen through restriction, shortcuts, or one size fits all approaches. It happens when nutrition is personalised and designed around an individual’s unique biology, lifestyle, and goals. He takes the latest scientific research and translates it into strategies that are practical, sustainable, and tailored to each person. He does not simply provide meal plans. He teaches people how to understand their bodies, interpret signals, and make informed choices that last a lifetime.
He also understands that mindset is just as important as what is on the plate. Overcoming years of severe illness showed him that the way people think about food, health, and their bodies can either trap them or empower them. This is why he focuses on education and empowerment, helping clients build confidence in their ability to make decisions that support their energy, performance, and overall wellbeing. By combining knowledge, strategy, and lived experience, he helps people move past temporary fixes or fad diets and create habits that truly last.
