Physician-Led Care That Measures What Matters
Longevity Medicine in Los Gatos
Longevity medicine is a practical field. It uses careful measurement and clinical judgment to understand how your body is aging right now, then builds a plan to keep you strong, sharp, and metabolically healthy for the decades ahead. At Lifetime Performance Medicine in Los Gatos, that work is led by physicians and grounded in data. We are the longevity division of Lifetime Surgical, and our clinic sits at 15965 Los Gatos Blvd, Suite 201, serving Los Gatos, Saratoga, Campbell, San Jose, and the wider South Bay.
What Physician-Led Longevity Medicine Actually Means
There is a lot of noise in the longevity space. Consumer gadgets, supplement subscriptions, and one-size-fits-all programs promise a great deal and measure very little. Our approach is different because it is clinical from the start.
Every member is evaluated by a physician-led team. You will see Dr. Richard Nguyen, DO, at least twice a year, and your ongoing care is guided by Morgan Carmean, ARNP, who leads the wellness clinic day to day. That structure means your results are read by people trained to interpret them, not by an app or a dashboard. Longevity medicine done well is honest about what the numbers show and what they do not, and it turns that reading into a plan you can follow.
Why Surgeon-Led Matters
Dr. Nguyen is a board-certified general and bariatric surgeon with a fellowship from Vanderbilt and more than 20 years of practice, working in the Bay Area since 2007. A surgeon spends a career making decisions where precision and follow-through are not optional. That discipline shapes how we practice longevity medicine. We measure carefully, we interpret conservatively, and we build plans that hold up over time. Bariatric and metabolic surgery also gives Dr. Nguyen a deep working knowledge of metabolism, body composition, and the physiology of long-term health, which are central to how the body ages.
The Lifetime Body Score: One Clear Picture of How You Are Aging
The center of our work is the Lifetime Body Score. Rather than handing you a pile of disconnected lab values, we organize your health into six domains and score each one. Together they give you a single, clear picture of where you stand and where to focus.
The six domains are:
Metabolic Health: blood sugar regulation, insulin, lipids, and the markers that drive long-term metabolic risk.
Cardiovascular Performance: the strength and efficiency of your heart and circulation, including VO2 max.
Body Composition: lean mass, fat mass, and visceral fat measured by DEXA.
Physical Performance: strength, mobility, and functional capacity through structured testing.
Recovery and Resilience: how well your body handles stress and recovers, tracked in part through wearables.
Biological Age: how old your body appears to be based on your biology, measured through PhenoAge and, at the Executive level, epigenetic age.
Scoring across all six domains lets us see patterns that a single test would miss. A strong cardiovascular number alongside a weak metabolic number tells a very different story than the reverse, and your plan reflects that.
Everything Behind Your Lifetime Body Score
Your score is powered by a comprehensive health assessment that goes beyond a routine checkup. We combine advanced diagnostics, performance testing, body composition analysis, and continuous health tracking to create a complete picture of your health.
/01
The Diagnostics Behind the Score
The Lifetime Body Score is only as good as the data underneath it. We use a comprehensive diagnostic workup so the score reflects your real physiology.
/02
Comprehensive Biomarker Panel
We run a panel of more than 80 biomarkers covering metabolic health, cardiovascular risk, hormones, inflammation, organ function, and nutrient status. This is a far deeper look than a standard annual physical, and it is the foundation for tracking change over the year.
/03
VO2 Max and Cardiovascular Testing
VO2 max is one of the strongest measured predictors of long-term health. We test it directly so your cardiovascular fitness is a number, not a guess.
/04
DEXA Body Composition
DEXA gives us precise lean mass, fat mass, visceral fat, and bone density. Body composition is one of the most actionable levers in longevity, and DEXA measures it accurately.
/05
Functional and Wearable Data
Structured functional testing shows how you actually move and perform. Wearable data adds a continuous view of sleep, recovery, and daily strain between visits.
Your Physician-Built 12-Month Plan
Using your Lifetime Body Score and diagnostic results, Dr. Nguyen and the team create a physician-designed 12-month plan tailored to your unique health profile.
Your plan covers training, nutrition, and targeted clinical care, and is regularly adjusted as your data changes to keep you progressing toward better health.

Answers To Your Most Asked Questions
We believe in transparency. Here are answers to the most common questions about our approach and programs.
It is a clinical approach that measures how your body is aging using detailed diagnostics, then builds a plan to protect your long-term health. At our clinic it is led by physicians and organized around the Lifetime Body Score.
You will see Dr. Nguyen at least twice a year. Your ongoing care between those visits is led by Morgan Carmean, ARNP, who runs the wellness clinic.
No. Membership is our primary model and gives the most value over time, but single tests such as DEXA or VO2 max are available a la carte.
