In this episode of Longevity by Design, host Gil Blander sits down with Florence Comite, MD, physician-scientist and founder of the Comite Center for Precision Medicine & Healthy Longevity. They explore why a one-size-fits-all approach to longevity falls short and how personalized data, from biomarkers to genetics, can spot early signs of disease before symptoms appear.
Florence explains her “Nof1” method, which uses deep testing, wearables, and personal history to craft precise health plans. She highlights how sleep, more than exercise or diet, shapes long-term health but remains hard for most people to optimize. Using real-world examples, Florence shows why tracking markers like insulin and hormones matter, and why most people need support to turn health knowledge into action.
The conversation covers the limits of standard medical care, the value of knowing your family history, and how even the best routines must adapt over time. Florence urges listeners to get curious about their own data and take steps—however small—toward better health.

Sleep Is the Cornerstone of Lifelong Health
Most people try to outwork a lack of sleep with exercise or diet, but this approach misses the mark. Deep, consistent rest shapes everything from hormone balance to weight, mental sharpness, and resilience against disease. Even small sleep deficits add up, pushing the body toward cravings, poor decision-making, and higher risks for metabolic issues. Improving sleep quality—focusing on deep and REM cycles, not just the number of hours—pays off in real, lasting health benefits. Tools like wearables can help track patterns and reveal what works, but real change comes from building habits that support restful nights. Simple steps like setting a routine bedtime, keeping the room cool, and limiting alcohol or late meals can move the needle. In the long run, sleep isn’t a luxury or an afterthought—it’s the foundation for every other healthy choice.
Personalized Data Beats One-Size-Fits-All Medicine
Traditional medicine relies on averages, but people aren’t average. Genetics, lifestyle, and even identical twins’ biology vary widely, so health solutions need more nuance than standard guidelines. By tracking a wide range of biomarkers—like insulin, hormones, and metabolic markers—individuals can spot problems early, sometimes years before symptoms. This approach puts the focus on prevention, not just treatment after the disease appears. Continuous glucose monitors, advanced lab tests, and personal history help build a unique health blueprint for each person. When care gets this personal, small, targeted changes can make a big difference in outcomes. The best results come from understanding your own data and adjusting your plan as you age, rather than following generic advice or influencer trends.
Know Your Risks—Then Take Action
Everyone inherits a unique genetic deck, but genes don’t tell the whole story. Family history, environment, and habits shape long-term health in powerful ways. Knowing your family’s patterns—like heart disease, diabetes, or cancer—can reveal hidden risks and guide smarter choices. But knowledge alone isn’t enough. Action starts with regular checkups, asking for key tests beyond the basics, and tracking changes over time. Even if you can’t change your genes, you can influence how they express by managing stress, eating well, moving daily, and getting enough sleep. The goal isn’t perfection or copying someone else’s plan. Instead, it’s about making informed decisions, adapting as you go, and playing the cards you have for the best possible health span.
Moving From Reactive to Proactive Medicine
The discussion opens with a clear shift from traditional, reactive medicine toward a proactive approach grounded in early detection and prevention. The conversation highlights how conventional care often waits for symptoms, while more personalized methods can identify risk and disease before they surface. By linking data points from different systems, it’s possible to spot trouble early and intervene before it becomes a crisis. The proactive mindset stands on understanding each person’s unique biology, not just responding to problems as they arise.
“I realized that when I looked at this data, I could see emerging disease even if people didn't have symptoms. And they used the fact that in their thirties, you're starting a family, you're working, it's very hard to get in the gym. It's very hard to eat right and get enough sleep. But even those individuals who focused on themselves noticed a decline... Why do we wait until they have symptoms before we jump all over it? Which is the way conventional medicine treats people. Even prevention isn't enough for me. It has to be proactive.”
The Power and Limits of Genetics
The episode explores how genetics and lifestyle interact to shape health outcomes. Genetics may load the gun, but lifestyle pulls the trigger. While family history and DNA set a baseline for risk, daily choices can change the path ahead. Understanding your own genetic makeup helps you focus on what matters most for prevention, such as reducing inflammation and monitoring specific nutrients. This view encourages everyone to take ownership of their health, recognizing both the power and limits of what they inherit.
“I have to say that the common thinking is that 35% genetics and 65% lifestyle. Genetics loads the gun, but lifestyle pulls the trigger. I agree with that a little bit, but I really think that the propensity to disease rests in our DNA and genetics and we can modify expression, epigenetic expression of disease by, for example, reducing inflammation... By understanding your family history, those are genes that express themselves. That is a great first start to deciding the choices that you're gonna make and what interventions make the most sense for you.”
Hormonal Health: Why Measurement and Balance Matter
Hormones play a central role in long-term health for both men and women. The discussion breaks down how hormone levels change with age and the importance of measuring—not guessing—what’s happening in the body. Both too little and too much can lead to problems, and the right balance often requires regular testing and adjustment. The episode calls out gaps in standard care, like the lack of testosterone and estrogen testing, and explains why thoughtful hormone management can help prevent chronic disease and improve quality of life.
“I think we do people a disservice when they did the Women's Health Initiative trial, it threw everybody off... A lot of conventional medical doctors don't think men's hormones change. And I can tell you for a fact that they change, and you can't get more testosterone by working out harder or by taking supplements... You cannot manage what you do not measure, and then when you measure it, you need to manage it well. Most of those, especially those hormones that are coming in a U shape, you need to find the right place to have them. Too much is not good, but too little is not good.”
Individualization Over Influencer Trends
The conversation addresses the pitfalls of copying popular health routines or influencer strategies. There’s no universal solution—what works for one person may not work for another. Success comes from understanding your own data, monitoring trends, and making adjustments as your body and life change. The highlight reinforces the need for experimentation, staying flexible, and being wary of one-size-fits-all advice, even from well-known voices in health and wellness.
“I think the myths about longevity, maybe, to me, that if you do everything right, you're gonna be fine. I've seen too many people who think they're following the Brian Johnson way of living life, or the, you know, Huberman, who's very prominent, and he's an excellent scientist. But the thing is, you can't apply what other people do necessarily to yourself... It's about being selective about your makeup and what your prototype is to be able to stop things from progressing and keep your health for the rest of your life.”
