MettleSense · Evidence Base

The evidence
behind the research.

MettleSense projects are informed by peer-reviewed literature, established datasets and recognised reference sources. This evidence base documents selected research used in the design and development of Shield and Lean.

Featured · Research Notes

Field notes &
thought leadership.

Independent research notes, technical explorations and practitioner perspectives on applied AI, agentic automation and the systems developed through MettleSense.

MettleSense Shield · Cardiac & HRV

Rhythm screening
& heart-rate variability.

The 9-condition classifier and 5-metric HRV fingerprint are built on established clinical signal-processing and electrophysiology literature.

MettleSense Lean · Nutrition & Recovery

Weight intelligence
& sports physiology.

Sugar Bomb™, glycogen retention, EPOC, recovery windows, injury-risk load and electrolyte replacement each map to a published source.

Reference Databases

Where the macros
come from.

No "curry — 200 kcal" placeholders. Every food item is sourced from a recognised nutritional database.
