ABOUT.
Fx Health was originally established as a performance nutrition consultancy, working with athletes and teams seeking marginal gains at the highest level, including supporting the Cambridge University Boat Club during a winning season.
Over time it became clear that many of the same principles were needed outside of sport. Senior professionals, business owners and high-achievers operate under significant pressure, managing complex diaries and responsibilities, yet often feel surprisingly out of control with respect to their own weight, energy and health.
Fx Health focuses on helping individuals reduce excess weight, improve day‑to‑day energy and regain a sense of control around food, through structured nutrition and lifestyle coaching. We help to bring their health and body back in line with the standards they expect elsewhere in life.



The practice is led by Leo De Watts, Fx Health practitioner and coach. Having experimented extensively with conventional high‑carbohydrate advice, Leo ultimately found that a carefully structured low‑carb, whole‑food and intermittent fasting approach provided the most reliable, sustainable results for himself.
The 12‑Week Low‑Carb & Fasting Reset is built from that experience, informed by current evidence, and delivered with the discipline inherited from our performance roots.
Fx Health does not provide medical treatment. We offer structured nutrition and lifestyle coaching for adults who value a considered, pragmatic approach, and who are prepared to engage with the process.
