Your walk
03Body
Which sounds most like you, standing relaxed?
Measure first thing in the morning, tape flat on the skin, not pulled tight. Waist at the navel, neck just under the Adam's applevoice box, hips at the widest point.
Fill in the boxes for an estimate.
From a scan or calipers. Use the same method each time.
Lean mass
Everything that isn't fat: muscle, bone, organs and water.
A scan, calipers and a tape all disagree by a few per cent. Use the same method each time and watch the trend.
04Calories
From your watch or fitness tracker, if it shows one. Optional: leave it blank and it is worked out from your weight and minutes.
Your maintenance
For your phase
Check against your watch
Watches tend to read 15 to 20% high on total calories. Put in your watch's average daily total and it's shown with that taken off, next to this page's number.
