Frequently Asked Questions

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.

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.

LifeLab offers several levels of testing and care: Metabolic and Weight-Loss AssessmentIncludes 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 LossFor patients who want to lose weight, improve metabolic health, and reduce cardiovascular risk through a structured, medically supervised program. VO₂ Max TestingMeasures cardiovascular fitness, training zones, aerobic performance, and fat-burning efficiency during exercise. VO₂ Max + Resting Metabolic RateCombines exercise and resting metabolism testing for patients focused on weight loss, fitness training, GLP-1 treatment, or body composition goals. Full Concierge MedicineComprehensive ongoing care for patients who want direct physician access, advanced prevention, metabolic testing, interpretation, and a personalized health plan.

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.
