Why metabolic breath analysis?

Precision testing that explains the “why” behind your symptoms.

Metabolic breath analysis measures how much oxygen you use and how much carbon dioxide you produce. From this, we can see whether you’re burning more carbohydrates or fat, how efficiently your body uses energy, and how your metabolism responds to rest, stress, and activity.

See what your body is actually doing

Move beyond “eat less, move more.” Discover if your metabolism is suppressed, overly stressed, or simply mismatched with your current nutrition and training.

Personalised, not templated

Your results guide tailored recommendations for nutrition, movement, recovery, and pacing—aligned with your medical history, medications, hormones, and life stage.

Designed to work with your care team

We regularly support clients referred by physicians, dietitians, therapists, and coaches. Your data can complement existing treatment, not replace it.

Energy Deficiency & Hormonal Suppression

Women & Men • Under-Fueling • Menstrual Disruption • Low Testosterone • Chronic Fatigue

Energy deficiency is not simply about eating less — it is about whether your body has enough usable energy to support normal hormone production, recovery, and daily function. Hormones such as estrogen, progesterone, testosterone, thyroid hormones, and cortisol are tightly regulated by how efficiently your body produces energy, uses carbohydrates and fats, responds to stress, and maintains stable blood sugar.

When energy intake, absorption, or utilization is insufficient, the body adapts by downregulating non-essential systems, including reproductive and anabolic hormone production. Metabolic breath testing measures how efficiently your body produces and uses energy at rest and under mild stress, providing a real-time view of whether your physiology is operating in a fuel-deficient or stress-adapted state.

  • Energy production and efficiency at rest

  • Carbohydrate and fat utilization patterns

  • Blood sugar regulation and recovery capacity

  • Stress physiology and chronic sympathetic activation

  • Resting metabolic rate (RMR) and true daily energy needs

  • Signs of metabolic suppression or under-fueling

  • Irregular or absent menstrual cycles and loss of ovulation

  • Low testosterone in men and women

  • Thyroid suppression, chronic fatigue, and poor recovery

  • Reduced bone density, muscle loss, mood changes, and sleep disruption

  • Personalized guidance for nutrition, meal timing, exercise adjustments, recovery, and lifestyle changes to restore hormonal balance

Eating Disorders & Chronic Dieting Histories

Women & Men • Restrictive Eating • Binge/Purge Patterns • Yo-Yo Dieting • Metabolic Recovery

Chronic dieting and eating disorders are not just about food — they profoundly affect how your body produces and uses energy. Over time, prolonged restriction or disordered eating can disrupt hormones, appetite regulation, mood, and long-term metabolic health.

Metabolic breath testing provides a real-time view of how your body is functioning after periods of under-fueling. It helps identify protective metabolic adaptations caused by scarcity, revealing whether your physiology is operating in a suppressed, stress-adapted state that can slow recovery, weight normalization, and hormonal balance.

  • Resting metabolic rate (RMR) and true energy needs, often lower after chronic dieting

  • Carbohydrate and fat utilization inefficiencies

  • Metabolic flexibility and ability to adapt to energy intake or activity changes

  • Appetite and satiety regulation disruptions
