Scan Reveal
Your body-fat guess is probably wrong
The short version
- The mirror moves the goalposts
- You're calibrated on highlight reels
- Smart scales wobble
- Memory keeps no baseline
- The fix isn't a better guess
The mirror moves the goalposts
Lighting, a pump, time of day — the same body looks two different numbers apart between morning and midnight.
You're calibrated on highlight reels
Comparing yourself to lit, filtered, peak-day physiques online skews everyone's estimate of what any percentage looks like.
Smart scales wobble
Bioimpedance swings with hydration. Drink a litre of water and watch your 'body fat' change — that's not your body, that's the method.
Memory keeps no baseline
'Leaner than last month?' is unanswerable without a dated number. Feelings drift; data doesn't.
The fix isn't a better guess
It's measuring the same way every time. A photo scan gives an estimate plus a trend — and the direction of that trend is the honest answer.
