How to read what follows Below this point the page switches into lab mode — a dark dashboard built for charts, status lights, and dense data. Green is on target. Amber means watch. Red means address. The aesthetic is intentional: the rest of the site is an editorial publication; this section is the instrument panel. Every number here is also discussed in plain language in the journal.

Active investigations

🔴 #1: CPAP Adherence — the $0 intervention worth more than the entire supplement stack

Confirmed sleep apnea (AHI 6.86, Oct 2022). Oura SpO2 shows moderate OSA (BDI 10–19/hr, SpO2 95.9%, 2-20 nights/month below 95%). CPAP machine owned but rarely used. Treating OSA would simultaneously improve: resting HR (−3-5 bpm), hs-CRP (−0.5-1.0), HOMA-IR, and sleep quality. This is the single highest-ROI intervention in the entire protocol.

🔴 #2: Free T4 declining — 1.03 → 0.87 → 0.97 → 0.70 ng/dL

Consistent downward trajectory across 4 panels despite normal TSH (1.23). This dissociation suggests central hypothyroidism or conversion issues. Low T4 contributes to elevated HR, reduced VO2 Max, and metabolic sluggishness. Next panel must include: Free T3, Reverse T3, TPO antibodies.

🔴 #3: VO2 Max 34.2 — volume without intensity

Despite 23K steps/day and 63 workouts/month, VO2 Max declined from 40→34 because 95% of exercise is walking (HR ~103). Zero Zone 2 cardio, near-zero resistance training. Add: 3× Zone 2 (130-145 bpm, 30-45 min) + 2× resistance + 1× intervals per week.
