Dr Dan Reardon is an NHS A&E doctor and lifestyle medicine physician specialising in deprescribing, metabolic health, and GLP-1 exit strategy. He holds an MB ChB from the University of Wales College of Medicine, a BSc in Human Anatomy from Cardiff University, and an MSc in Mental Health from the University of Birmingham.

He continues to work in frontline NHS emergency medicine alongside his private practice. He co-founded and was formerly the CEO of Fitness Genes, a £10M+ venture-backed personalised health company, where he conducted over 3,000 direct clinical data reviews, interpreting DNA, blood panels, and metabolic data into personalised plans. He is Chief Medical Advisor to women’s over 50’s workout program Goodnick and has previously served as Medical Advisor to the Cambridge Weight Plan 1:1.

Dr Reardon’s private practice focuses on four areas: GLP-1 exit strategy for patients stopping Mounjaro, Wegovy, or Ozempic; deprescribing and medication review; clinical data interpretation; and metabolic health optimisation. He has been featured in the New York Times, Scientific American, GQ, BBC Radio London, and NBC The Doctors.

Most of my patients arrive with data and no plan.
Blood tests that came back “fine.” A medication list that’s grown over the years without anyone reviewing the whole picture. Months of CGM data and no one to interpret it. A GLP-1 they’ve stopped, or want to stop, and nothing in place for what comes next.

I built my practice around that gap. Not because medication is the problem, sometimes it’s entirely right, but because the system rarely has time to ask whether it still is.

I still work in NHS A&E. Frontline emergency medicine gives you a precise view of what happens downstream when chronic disease is poorly managed and medication lists are never reviewed. It shapes how I think about every patient I see privately.

Outside the clinic, I live the way I advise. I train consistently, take cold plunges, eat well, and take sleep seriously, not as a performance protocol, but because I genuinely enjoy it. I was Science Editor at Muscle & Fitness for a period that took me to some of the most iconic gyms in the world, which gave me an early and deep education in what serious physical culture actually looks like in practice.

I read constantly, across medicine, science, business, and philosophy. I’m genuinely interested in entrepreneurship, in how things get built, and in conversations about where humanity is heading. I’ve spoken at conferences worldwide on health, performance, and longevity. I find the best conversations happen over good coffee or a long dinner with people who think seriously about things.

Friends and family come first. Everything else is built around that.
