David's career began in personal training and fitness instruction. He was good at what he did. But he kept encountering the same pattern: disciplined women doing everything right and getting nowhere. Harder wasn't the answer. More restriction wasn't the answer. Something else was happening inside their bodies that no program was addressing.

That kept him studying — female physiology specifically, at a level most fitness professionals never reach. The internal systems that govern how a woman's body responds to stress, food, and training as she moves through her 40s and 50s. The more he learned, the clearer it became: the problem was never discipline. It was biology that no one had investigated. That realization became the foundation of the Functional Reset Method.

David is also in recovery — sober, and someone who navigated years of binge eating while working through that process. That experience shapes how he coaches. He meets women where they are, without judgment, because he has been somewhere complicated too, and made it to the other side.

Nathalie holds a Master's degree in Clinical Psychology from Columbia University. That foundation shapes everything about how she works — and how KYLO's coaching methodology was built. She didn't just contribute to the curriculum. She helped architect the approach itself: the deep listening, the refusal to do anything extreme, the commitment to treating each client as a whole person rather than a set of metrics to optimize.

Her clinical background gives her a lens that most health coaching programs don't have access to. She understands the psychological weight of chronic health struggles — the erosion of self-trust that comes from years of trying and not seeing results, the relationship between stress and physical symptoms, and the difference between compliance and genuine readiness to change. These aren't soft considerations at KYLO. They are core to the method.

Nathalie's work ensures that the Functional Reset Method never becomes purely transactional. Every client is assessed as a complete picture — her history, her psychology, her life — not just her labs. She holds the standard that this program was built around: comprehensive coaching that goes as deep as the person in front of you needs it to go.
