MettleSense Lean · Athlete Body Intelligence
A body intelligence system for athletes. Logs your food from plain English, decodes every weight fluctuation with peer-reviewed science, and tracks your recovery the way a sports physiologist would.
Added sugar above 50g/day triggers the Sugar Bomb flag. The mechanism, cited: 150g glycogen repletion × 3g water per gram of glycogen = ~450g water spike on the scale.

Tracked individually against your medication reference sheet.
Some medications cause clinically documented water or weight retention. Lean tracks each individually — with the mechanism, expected magnitude, and the exact date it resolves.
Sodium retention via mineralocorticoid effect. e.g. Prednisone, Dexamethasone. Magnitude scales with dose and duration.
COX inhibition → reduced renal prostaglandin → sodium + water retention. e.g. Ibuprofen, Naproxen.
H1-blockade reduces fluid mobilisation in some users. Mild effect. e.g. Cetirizine, Loratadine.
Oestrogen upregulates aldosterone via the RAAS axis → cyclical water retention of 0.5–2 kg.
EPOC by zone, ACWR injury risk, sodium sweat loss, glycogen window — computed from your actual session data, not population estimates. Run 10.25 km, 87 min. Every number cited.
