A practical trend tool

Estimate maintenance from your own logged trend

Use your dated weight and calorie log to estimate energy maintenance from observed change. This is an approximation, not a metabolic measurement.

Enter your dated log

Paste rows or import a CSV with date, weight, calories. Use YYYY-MM-DD dates and one row per day. Calculations stay in this browser session; nothing is uploaded or saved.

How the calculation works

Average recorded daily intake is adjusted by observed weekly weight change using an assumed 7,700 kcal per kg. This fixed energy-density assumption can be inaccurate as water, glycogen, tissue mix, and logging errors vary. Compare with a formula estimate rather than treating either as exact.
