Darren Tebbenham

Metabolic & Mental Health Expert

Darren Tebbenham is a leader in metabolic and mental health, behaviour change and human performance, known for a single powerful idea: metabolic health is mental health.

His career began in academia, where he lectured in sport and exercise psychology. But he grew frustrated by a gap he saw everywhere — knowing what to do rarely helped people actually do it. Information, willpower and good intentions were never enough. So he left the lecture hall to build methods that change behaviour from the inside out, starting with identity and psychology before habit and biology.

That work became a framework designed to create lasting change rather than short-lived results. Darren has authored two books on the psychology and biology of transformation and become a trainer of trainers, teaching his approach to more than 3,000 health and fitness professionals across 30+ countries.

He is also the co-founder of Gloo Fitness, where his methods are put into practice every day, and works with organisations on the metabolic roots of energy, mood, resilience and performance. Through keynote talks, BodyScan assessments and a live 10-week programme, he helps companies measure their people's metabolic health and give them the tools and the accountability - to change it.

His message to leaders is simple: the mental health, energy and productivity of your people has a physical foundation - and it can be measured and improved.

This was the case at NFU Mutual where Gloo delivered more than 160 BodyScans in a morning before two talks to staff about their results. Indeed, Vanessa Jensen from NFUM said "The best decision I made was joining the 10-week challenge - and I've never looked back, it was brilliant. I was therefore delighted when they were able to deliver the BodyScans and motivational talks at my work, and I must say they've been so well received!"

Darren's mission is straightforward: metabolic health is mental health. Body and mind are inextricably linked, and both perform at their best only when we treat them as one
