Your health was never really one number. It is a system: how you turn food into fuel, how your heart performs, what your body is made of, how strong you are, how well you recover, and how your hormones support all of it. The Lifetime Body Score is our way of translating that whole system into a single number from 0 to 100, calculated from real clinical data, so you can see clearly where you stand and watch what improves over time.
Dr. Richard Nguyen, DO built the score for our Los Gatos practice because members kept asking the same fair question: I have 80 pages of lab results here, so how am I actually doing? This is our answer to that.
The score is a composite drawn from six clinical domains. Each domain is scored from 0 to 100 against age- and sex-adjusted reference ranges, and the domains are then combined using weighted averages to produce your final number. The inputs come from your lab panel, physical exam, body composition testing, and functional performance testing, all gathered at our clinic. Because every input is a real measurement, the score moves when your body changes. It is not a quiz or a lifestyle estimate. It is your physiology, gently summarized into something you can actually use.
Metabolic efficiency carries the most weight, at 25 percent, because it sits upstream of so much chronic disease. It reflects how well you regulate glucose, respond to insulin, balance your lipids, and process through your liver, drawing on markers like HbA1c, fasting glucose, fasting insulin, triglycerides, HDL, and ALT, plus derived measures like HOMA-IR and the triglyceride-to-HDL ratio.
Body composition makes up 20 percent, and it is about what your weight is made of rather than the number on the scale: body fat percentage, visceral fat, lean mass index, and muscle-to-weight ratio, measured by body composition testing and DEXA in the higher tiers. Cardiovascular performance is another 20 percent, capturing your aerobic capacity and vascular health through VO2 max, resting heart rate, and blood pressure, and VO2 max alone is one of the strongest predictors of long-term health in the research.
Strength and function accounts for 15 percent, the things your body can actually do, measured through grip strength, sit-to-stand, plank time, and single-leg balance, tests that predict healthy aging remarkably well and are almost never part of conventional care. Recovery and inflammation is 10 percent, looking at whether your system is repairing or quietly under strain, with hs-CRP alongside your sleep and recovery data. And hormonal context rounds it out at 10 percent, the signaling layer that supports everything above, read through total testosterone, SHBG, and thyroid function.
Scores fall into four friendly bands. From 90 to 100 is optimal, elite metrics across the board. From 75 to 89 is good, above average with a few specific areas worth refining. From 50 to 74 is moderate, a solid average with real room to improve. And from 0 to 49 is the range that warrants focused attention. Most new members land in the moderate band, often with one strong domain and one weaker one, and that spread is the genuinely useful part. A 71 built on excellent cardiovascular fitness and weaker metabolic health calls for a completely different plan than a 71 with the reverse profile.
Three reasons, really. The first is priorities: the domain weights reflect what most drives long-term health, so your weakest high-weight domain becomes the natural first focus of your plan. The second is trend, since a single score recalculated through the year shows whether the plan is working in a way that scanning 80 separate values never quite could. And the third is clarity: a single number is easy to keep sight of, in a way that 80 individual values rarely are.
The Body Score also pairs naturally with PhenoAge, the validated biological age formula we calculate from your bloodwork. The Body Score reflects how your system is performing right now, while PhenoAge gives a sense of what the years have asked of you so far. Together, they act as the dashboard for your 12-month plan.
The score is part of every membership at our Los Gatos clinic. Your first visit is a diagnostic intake with Morgan Carmean, ARNP: a comprehensive blood draw, body composition, and functional testing. At your second visit, Dr. Nguyen walks you through your Body Score domain by domain and builds your first 90-day plan around what the data shows. Members in our Optimization and Executive tiers have their scores recalculated through the year as labs repeat. Foundations memberships start at $4,500 a year, and we serve members from Los Gatos, Saratoga, Campbell, San Jose, and across Silicon Valley.
Is the Lifetime Body Score the same as biological age?
Not quite, they are complementary. PhenoAge estimates how old your body is based on blood markers, while the Body Score measures how well your body performs across six domains right now. We calculate both for every member.
Can my score go up?
Yes, and that is the whole point. Because every input is a measurement you can influence, focused work on your weakest domain moves the composite. Many members see early movement within the first few months.
What is a good Body Score?
Above 75 puts you in the good band, and above 90 is optimal. Where you start matters far less than the direction you move, and your physician will set realistic targets domain by domain.
Can I get a Body Score from my existing lab results?
Partly, but not completely. The score relies on functional and body composition testing that standard labs do not include, which is why the baseline is done at our clinic in Los Gatos.
Is the scoring transparent?
Completely. The domains, weights, and bands are exactly as described here, and Dr. Nguyen walks every member through their own calculation at the reveal visit.
It is hard to improve a system you have never measured. Book a consultation at our Los Gatos clinic, and we will walk you through how your baseline would be built.
Every membership begins with the same baseline panel and the same two visits: an intake with Morgan, then your Body Score reveal with me. If you have been guessing about your health for years, the first step is to stop guessing.
Dr. Nguyen has practiced in Los Gatos since 2007. He leads every membership: the Body Score reveal, the 90-day plan, and the annual review.
