Concierge Medicine & Advanced Metabolic Exercise Testing
At LifeLab, we are more than a high-touch personalized concierge medicine program. We are also a sophisticated testing center focusing on V02 max, resting metabolism, body composition and cardiometabolic risk factors. We help you measure your health and then turn it into action plans for better healthspan.
Personalized Metabolic Medicine for a Longer, Healthier Life
Elevating Wellness & Preventive Medicine Across San Francisco
LifeLab Concierge Medicine is a physician-led metabolic medicine and healthy aging practice in San Francisco. We combine advanced testing, individualized medical interpretation, and long-term coaching to help patients understand and improve their metabolism, fitness, body composition, sleep, glucose control, and cardiovascular risk. Some patients come to LifeLab for comprehensive concierge care. Others come for focused metabolic testing, such as VO2 max, resting metabolic rate, body composition, labs, or an executive physical. The goal is the same in both cases: to replace generic advice with precise, measurable information and a practical plan. The LifeLab Protocol is built around a one-year pathway focused on sleep, sugar, fasting, fitness, and reassessment, with the goal of improving insulin resistance, weight, metabolic health, and long-term healthspan.

What is LifeLab Concierge Medicine?

Do I have to join the concierge practice to use LifeLab?
No. LifeLab offers both standalone testing services and ongoing concierge medicine.
You can begin with a single VO2 max test, add resting metabolic rate testing, schedule a more comprehensive executive physical, or enter one of our deeper medical programs. Some people simply want high-quality testing and interpretation. Others decide they want a longer-term physician-guided plan after seeing their results.
This allows patients to start at the level that makes sense for them.
What services do you offer?
LifeLab offers several levels of care and testing:
VO2 Max Testing
For patients who want to measure cardiovascular fitness, training zones, fat-burning efficiency, and aerobic performance.
VO2 Max + Resting Metabolic Rate
For patients who want to understand both exercise metabolism and resting calorie expenditure, especially in the setting of weight loss, fitness training, GLP-1 medication use, or body composition goals.
Executive Physical
A more complete metabolic and cardiovascular assessment, including advanced labs, body composition, ECG, VO2 max, resting metabolic rate, and physician interpretation.
LifeLab Mini Program
A more guided program for patients who want structured help improving weight, glucose control, fitness, sleep, and metabolic health.
Full Concierge Medicine Program
A comprehensive ongoing relationship for patients who want direct physician access, longitudinal metabolic care, prevention, testing, interpretation, and a personalized healthspan plan.
How do I know which LifeLab service is right for me?
A good way to think about LifeLab is that each service gives you a different depth of insight.
If you mainly want to know your fitness level and training zones, VO2 max testing is a good starting point.
If your goals include weight loss, metabolic health, or preserving muscle while losing fat, VO2 max plus resting metabolic rate gives a fuller picture.
If you want a broad assessment of cardiovascular and metabolic risk, the executive physical is the better fit.
If you want help making sustained changes in sleep, nutrition, fasting, exercise, body composition, and glucose control, the LifeLab Mini Program or full concierge program is more appropriate.
If you want ongoing physician access and a long-term plan, the concierge program is the most complete option.
Who is LifeLab best suited for?
LifeLab is especially well suited for people who want measurable, physician-guided improvement in health and performance. This includes people who:
want to lose weight or preserve muscle during weight loss
are using or considering GLP-1 medications such as semaglutide or tirzepatide
have prediabetes, insulin resistance, metabolic syndrome, or a strong family history of diabetes or heart disease
want to improve VO2 max, fitness, endurance, and training efficiency
want a more sophisticated executive physical than a standard annual exam
want to live longer, stay stronger, and preserve healthspan
The practice is built for people who do not just want to be told that their labs are “normal.” They want to understand what their numbers mean, what to do next, and how to measure whether their health is actually improving.
