Start with Nutrition Coaching

DEXA Scan

Full-body composition analysis measuring bone density, lean muscle, and fat mass with clinical-grade precision. Results reveal exactly where your body stores fat and muscle down to individual body segments.

Resting Metabolic Rate (RMR)

Measures exactly how many calories your body burns at rest. Removes the guesswork from nutrition targets and shows how your metabolism compares to predictions.

VO₂ Max Testing

Determines your maximal aerobic capacity and the heart rate zones where you actually burn fat vs. carbohydrates. Essential for endurance athletes dialing in fueling strategy.

Data Drives the Plan

Test data isn't just numbers to look at once — it's the foundation of your nutrition strategy.

Body composition informs sport and health outcomes
RMR removes guesswork from energy needs.
VO₂ Max guides fueling strategy around training zones.

We bridge the gap between raw clinical data and actionable, daily nutrition coaching.

How to Get Started

Choose the path that fits your readiness and goals.

Nutrition Coaching First

Build structure, consistency, and confidence with ongoing support. We interpret any test results (DexaFit, blood work, or medical) and use testing when it's helpful — not before you're ready. Ideal if you want personalized nutrition guidance and prefer to add testing later. Can also be done as a single consult or ongoing support.

Learn More About the Tests

A DEXA (Dual-Energy X-ray Absorptiometry) scan uses two low-dose X-ray beams to differentiate between bone, lean tissue, and fat tissue. It provides highly accurate measurements of body composition, bone mineral density, and regional fat and muscle distribution, making it one of the most reliable methods for tracking changes over time. This information can be used to guide body composition goals, monitor muscle gain or fat loss, assess bone health, and evaluate the effectiveness of nutrition and training programs.

What is an RMR Test?

A Resting Metabolic Rate (RMR) test measures the amount of oxygen your body consumes and carbon dioxide it produces while at rest. Using indirect calorimetry, it calculates the number of calories your body requires to support essential functions like breathing, circulation, and cellular metabolism. This information can be used to personalize calorie recommendations for performance, weight management, body composition, and recovery.

A VO₂ Max test measures the maximum amount of oxygen your body can take in, transport, and utilize during progressively harder exercise. By analyzing your breathing during exercise, it provides an objective measure of aerobic capacity and helps identify training zones and physiological performance thresholds. This information can be used to optimize training intensity, monitor fitness improvements, evaluate endurance performance, and guide race preparation.
