A practical tool, a clearer next step
Body Recomposition Tracker
Compare entered weight and waist changes without pretending to measure muscle gained or fat lost.
Use averages measured under similar conditions, not single unusually high or low readings. This manual comparison estimates no tissue masses. “Broadly stable” here means weight change below 1%; a waist change over 1 cm is a display rule, not a clinical threshold. Weight: 35–300 kg; waist: 40–200 cm.
For adults. These educational estimates are not a prescription, diagnosis or a plan for pregnancy, breastfeeding or a medical condition.

Common questions
Can stable weight mean progress?
It can. A smaller waist alongside stable weight is useful context, but cannot prove the exact composition of the change.
