OWLiFTSee sample brief
Sample / fictional demo data“Marcus” is invented. Nothing here is a real person or real measurements, this is a read-only walkthrough of the OWLiFT weekly loop.

This week's decision

The loop OWLiFT runs every week: baseline, scan, context, verdict, next decision. Below is one full cycle for the sample persona.

Progress is real. Don't overcorrect.

Two consecutive fasted morning scans on the same device support the trend. Sleep partially logged, bloodwork two months old.

  • Composition Signal
    Body fat percentage trending down 9 of 10 consecutive weeks. No lean mass compromise.

  • Fat-Loss Rate
    −0.43 kg/week (Theil-Sen). Inside the range that historically spares muscle at this body weight.
    Sustainable
  • Lean Status
    Lean mass holding within scanner error across 10 scans. No downward drift detected.

Evidence04 metrics · signal vs noise
Fat MassSignal
19.5 kg−0.7 kg

Clean drop under matched scan conditions.

Largest single-week drop in the last four weeks. Body fat and fat mass moved together, lowering measurement-error risk.

Body FatSignal
19.6%−0.5 pp

Tracking the fat-mass move proportionally.

Down 2.8 percentage points from baseline 22.4%. Crossed below 20% for the first time in the available record.

Lean MassNoise / Stable
79.8 kg−0.1 kg

Within measurement noise. No loss signal.

Evolt 360 has roughly ±0.7 kg error on lean. Useful only because no negative drift has emerged across 10 scans.

Visceral FatSignal
Level 70 levels

Below the level-10 baseline threshold.

Visceral has stepped down from 10 to 7 across the program. Trajectory is more informative than the snapshot.
