METABOLIC ASSESSMENTS
And Red-S screening
Service Description
Why it matters Precision beats estimates. Generic formulas can miss your true Resting Metabolic Rate (RMR) by 15–25 %. We measure it directly with medical-grade gas analysis, so your calorie targets are built on actual data. Early warning for RED-S. Two-thirds of endurance athletes drift into Low Energy Availability. A suppressed RMR is one of the first physiological red flags - which happens for both age groupers and pros. Catch it early and avoid potential bone-stress injuries, hormonal issues, and stalled progress. Body-comp clarity. We use medical grade calipers, and scale to assess with 1% of precision your body composition. This helps us accurately track changes, not just weight. What’s included 1. Indirect calorimetry RMR test (15 min, relaxed breathing). 2. Body-composition profile (lean mass, fat mass, % change potential). 3. Personalised report (48–72 h) • Measured vs. predicted RMR and what the gap means. • Daily calorie & macro ranges for rest, training, and heavy days. • Five example meal templates tailored to your dietary preferences. • Recovery and training pointers grounded in your numbers. 4. Optional 20-min video call to interpret results and set next steps. How to prepare Best scheduled in the morning. • Fast: no food, caffeine, or alcohol for 5 h. • No smoking 2 h prior. • Skip hard workouts for 12 h; light mobility is fine. • Wear comfortable clothing; avoid compression garments. Ideal for • Endurance athletes aiming to fine-tune fuelling. • Strength athletes chasing lean mass without under-eating. • Anyone rebounding from injury, illness, or over-training. • Masters athletes wanting objective data on age-related metabolic change. Turnaround & follow-up You’ll receive your report within three days. If your results flag elevated RED-S risk, we outline referral options (sports dietitian, blood work) and a re-test timeline so you can track improvement rather than hope for it.
