Redwoods nearbyWhat RMR tells you
Three numbers that change the plan.
Generic calculators use population averages and can miss by 300+ calories. A direct measurement gives you a baseline, a fueling floor, and the math behind whatever goal you're chasing next.
01 · Baseline
Your true resting burn.
A direct measurement of how many calories your body spends at rest. Not a formula, not a wearable estimate.
Measured, not guessed02 · Fueling
Macros that match the math.
Translate your RMR into daily calorie and macro targets that fit your training load and recovery.
Applied to your week03 · Goal math
Cut, maintain, or build, with numbers.
Whether you're losing fat, gaining muscle, or recovering from a long diet, the deficit or surplus starts from a real number.
Weight-goal planningHow the test works
Non-invasive. Almost meditative.
The metabolic cart reads each breath (oxygen in, carbon dioxide out) and converts the exchange into calories burned per day. You lie down, breathe, and the machine does the rest.
- 01Arrive fasted and rested.4–6 hours without food, no caffeine or exercise that morning. Water is fine. Show up calm: stress skews the read.
- 0215 minutes of quiet breathing.Lie back with a light mask connected to the metabolic cart. Breathe normally while it measures oxygen in and CO₂ out.
- 03Analysis on the spot.We walk through your resting metabolic rate, substrate use (carb vs. fat), and what the numbers say about recovery and fueling.
- 04Coaching you can apply.A written report lands within 24 hours with calorie targets, macro ranges, and a plan for retesting every 8–12 weeks.
Who books this
Different goals, same starting number.
RMR isn't a weight-loss tool or a performance tool. It's the baseline every nutrition plan is built on. Here's how it lands for the people who come through the door.
Weight loss
Build a sustainable deficit from your actual baseline, not a population average that undercuts recovery.
Fuel the cut →Performance
Dial in training-day calories so hard sessions don't turn into chronic under-fueling and stalled adaptation.
Fuel the work →Recomposition
Find the narrow window where you can add muscle without excess fat. RMR sets the ceiling and floor.
Rebuild with data →Longevity
Track metabolic rate over time. A quarterly retest catches adaptive drops before they derail long-term goals.
Track the trend →Book a test
Stop guessing. Start fueling.
Grab a slot for a standalone RMR, or pair it with a fitness evaluation to anchor the nutrition plan in how you actually move and train.
