Testing And Analysis
MetabAcheck is the Bay Area’s Premier Metabolic Testing Center for Weight Loss and Athletic Performance
Welcome to MetabAcheck
At MetabAcheck we recognize the many benefits that accurate metabolism (RMR) and Vo2max testing can provide. Whether you are interested in losing weight, gaining muscle, improving performance, or periodic measurement as an early warning to a slowing metabolism as you age, our tests and expert analysis provide a blueprint for maximum success.


Why Choose MetabAcheck RMR – Vo2max Testing?
Accuracy
MetabAcheck gives you the most accurate measurement of your resting metabolic rate (RMR) and Vo2max. We utilize what is recognized as the “Gold Standard” of metabolism measurement, indirect calorimetry using the Pnoe Gas Analysis System, to determine the exact number of calories your body utilizes per day at rest.
Expert Analysis
A metabolism test is only as good as the person you have analyzing your results. Many companies utilize a technician to administer AND analyze your results. With 21+ years of metabolism testing experience, physician, weight loss, and body transformation specialist Dr. Jay administers and analyzes ALL MetabAcheck tests.
Proven Results
We feel our client’s results speak volumes. So, we invite you to browse our gallery of former and current clients and athletes. Whether your goal is to lose weight, gain muscle, improve performance, or just maintain your current body composition, MetabAcheck can help.
Break Plateaus
There is nothing worse than putting in effort and not seeing results. Whether you’re working out hard at the gym or focusing your effort on diet, the bottom line is that if you don’t see results, you probably won’t keep it up for long. Frustrated, many of our clients come to us after having not seen results for months and even years! Metabolism testing can quickly and easily identify the cause of your plateau so you can make adjustments and start seeing results again!
Affordable, Fast, & Easy
Being healthy is definitely not cheap and time is money! So the last thing any of us can afford to do is waste time and money reaching our health and fitness goals. Luckily, for less than the cost of some gym memberships, you can now get better, faster results and finally bridge the gap between your effort and your success! Sit back, relax, and breath….it’s as simple as that. The test itself only takes ten (10) minutes.
Versatility
No matter what diet (Weight Watchers, Jenny Craig, Nutrisystem, Keto, etc.) or fitness program (P90X, Crossfit, Zumba, 24hr Fitness, online personal training, etc.) you are currently doing, MetabAcheck metabolism testing can help. Let’s face it, none of these programs were designed specifically for YOU. MetabAcheck metabolism and fitness testing allows you to individualize ANY program in order to get the very best results possible!
