Advanced Testing, Medical Weight Loss and Preventive Care in San Francisco
LifeLab is a physician-led metabolic medicine practice focused on measurable improvements in weight, fitness, body composition, glucose control and cardiovascular risk. Patients can begin with a metabolic and weight-loss assessment, standalone V02 max or resting metabolic rate testing, or a comprehensive concierge medicine relationship. Each service is designed to replace generic advice with precise measurements, physician interpretation and a practical plan. The LifeLab approach brings together advanced testing, structured follow-up and personalized medical care so you can understand what your numbers mean, what to do next and whether your health is actually improving.
Physician Interpretation Makes the Difference
Advanced testing is most valuable when it leads to a clear medical plan
LifeLab combines metabolic and cardiovascular testing with physician interpretation, helping you understand what your results mean, which risks matter most, and what steps to take next.
Whether you begin with weight loss, fitness testing, or comprehensive ongoing care, our goal is the same: turn complex health data into practical, measurable action.

Frequently Asked Questions
What is LifeLab Concierge Medicine?
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.
Do I have to join the concierge practice to use LifeLab?
No. You do not need to join our concierge practice to use LifeLab.
You can start with a $249 metabolic and weight-loss assessment, which includes testing and a medical review of your health risks, goals, and potential benefits from weight loss. After the assessment, you may choose to join our medical weight-loss program for a monthly fee.
You may also book standalone metabolic and fitness testing to use with your own physician.
For patients seeking comprehensive ongoing care, LifeLab also accepts a limited number of concierge medicine patients.
This allows you to begin at the level that best fits your needs.
What services do you offer?
LifeLab offers several levels of testing and care:
Metabolic and Weight-Loss Assessment
Includes resting metabolic rate testing, body composition, blood work as needed, and a medical assessment. This is also the entry point for the LifeLab Weight Loss Program.
LifeLab Weight Loss
For patients who want to lose weight, improve metabolic health, and reduce cardiovascular risk through a structured, medically supervised program.
VO₂ Max Testing
Measures cardiovascular fitness, training zones, aerobic performance, and fat-burning efficiency during exercise.
VO₂ Max + Resting Metabolic Rate
Combines exercise and resting metabolism testing for patients focused on weight loss, fitness training, GLP-1 treatment, or body composition goals.
Full Concierge Medicine
Comprehensive ongoing care for patients who want direct physician access, advanced prevention, metabolic testing, interpretation, and a personalized health plan.
How do I know which LifeLab service is right for me?
A good way to think about LifeLab is that each service offers a different level of testing, treatment, and ongoing support.
If you want to understand your metabolism, body composition, and whether medical weight loss may be appropriate, start with the Metabolic and Weight-Loss Assessment.
If you are ready for structured, medically supervised weight loss, the LifeLab Weight Loss Program is the best fit.
If you mainly want to measure cardiovascular fitness, training zones, and aerobic performance, choose VO₂ Max Testing.
If your goals include weight loss, fitness, metabolic health, or preserving muscle while losing fat, VO₂ Max plus Resting Metabolic Rate provides a more complete picture.
If you want comprehensive ongoing care, advanced prevention, and direct physician access, the Full Concierge Medicine Program is the most complete option.
Who is LifeLab best suited for?
LifeLab is best suited for people who want measurable, physician-guided improvement in health, metabolism, 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, endurance, fitness, and training efficiency
want a more advanced health assessment than a standard annual physical
want to live longer, stay stronger, and preserve healthspan
LifeLab is designed for people who want more than reassurance that their results are “normal.” They want to understand what their numbers mean, what to do next, and whether their health is actually improving.
