John Sparks is the founder of SugarFreeZone® and EnergyBodyLife® and an Ambassador for the Preventive Health Collaboration.
With a Master’s degree in IT Management and a background in education and course development, John brings a strongly research-focused approach to metabolic health. His work draws on published scientific research, translating often complex evidence into practical, understandable ideas around food, movement, sleep, stress, mood and healthy ageing.
John’s career has included senior leadership and entrepreneurship in optics, college lecturing, property, radio broadcasting and complementary health. That varied experience has shaped his ability to communicate with different audiences and create welcoming learning experiences grounded in real life.
But this is also lived experience. At 75, John takes no regular prescription medication and uses the same real-food, movement and lifestyle principles that he shares through SugarFreeZone® and EnergyBodyLife® to support his own health and healthy ageing. He is not simply researching and talking about these changes—he is actively making them part of his own life.
John is also continuing his development through studies in counselling skills and metabolic health coaching.
Through SugarFreeZone® and EnergyBodyLife®, John aims to help people understand their bodies more clearly, make informed everyday choices and create practical changes that support greater health, confidence and autonomy.
