What it does

• Works out body fat with the US Navy formula from your neck, waist, hips and height.
• Shows fat mass and lean mass each week, so you see if you're losing fat or muscle.
• Tracks change from your start and from last week.
• Charts body fat and weight over time.
• Has a column for your smart scale reading so you can compare methods.
• Room for 52 weeks.

Why a spreadsheet and not an app

Your data stays in a file you own. No login, no monthly fee, no app that shuts down next year. Add your own columns if you want.

How to use it

1. Open the Settings tab. Enter your sex, height and units.
2. Once a week, same day and time, measure and fill in one row on the Log tab.
3. Check the Chart tab each month.
