What This Assessment Reveals
Four dimensions of your metabolic health
Autonomic Nervous System Balance
Insight into your body's stress and recovery balance — how well your sympathetic and parasympathetic systems are working together.
Heart & Lung Function
How efficiently your heart and lungs work together to deliver and use oxygen throughout your body.
Cellular Efficiency & Metabolic Health
How efficiently your cells produce energy and which fuel your body primarily uses at rest — fat, carbohydrate, or a mix.
Healthy Ageing & Longevity
Insights to support long-term health, vitality, and disease prevention — the foundation of a proactive wellness plan.
The Assessment
What to expect
Your assessment includes
- A short health questionnaire about your medical history and personal goals
- A 10-minute breathing assessment while you rest comfortably
- Accurate data about your metabolism and body function
- A personalised report interpreted in the context of your individual health goals
How the assessment works
- You breathe in oxygen through a comfortable mask
- Your lungs take in oxygen and deliver it to your body
- Your heart pumps oxygen-rich blood to meet your needs
- Your cells use oxygen and fuel to produce energy
- We analyse your results and prepare your personalised report

After Your Assessment
Receiving your personalised results
Your results will be analysed by Dr Kate and discussed during a 30-minute follow-up consultation, usually within 72 hours of your assessment. Your health questionnaire and any available laboratory results will also be reviewed, allowing us to interpret your metabolic assessment within the context of your overall health.
