BMITDEE Labs • Phase 1
Turn a TDEE estimate into your personal working estimate
Log morning weight and calorie intake. The tracker separates daily scale noise from the longer trend and compares your formula estimate with an approximate observed TDEE.
Educational planning tool only. It does not directly measure metabolism or diagnose a health condition.
This browser does not allow persistent local storage. You can test the tracker, but export a backup before closing the page.
1
Set your starting estimate
This is the formula-based TDEE you received from the BMITDEE calculator or another documented source.
Tip: a BMITDEE result page can link here with ?baseline=2430&weight=82.5&unit=metric to prefill these fields.

Adaptive dashboard
Build your calibration period
Enter weight and calorie intake consistently. The tracker waits for enough data before showing an adaptive estimate.
Weight trend
Daily measurements and a trailing seven-day average.
Daily 7-day average
Add two or more weight entries to draw the chart.
Calorie intake
Logged intake compared with your formula TDEE and planned target.
Calories
Add calorie entries to draw the chart.
2
Log a day
For weight, use similar conditions each time when practical.

Methodology
What the adaptive number means
The adaptive estimate is an approximation inferred from your own records. It is not a laboratory measurement of energy expenditure.
Calculation outline
- Entries are ordered by date and limited to your selected analysis window.
- A linear regression estimates the rate of weight change in kilograms per day.
- The tracker averages logged calorie intake over the same period.
- Approximate TDEE is calculated as average intake minus the estimated daily change in stored energy.
- A rough uncertainty range reflects calorie variability, scale noise and the amount of data available.
Approximate TDEE = average calorie intake − (weight trend in kg/day × 7,700 kcal/kg)
The 7,700 kcal/kg convention is a simplified short-term calibration assumption. Human weight change includes water, glycogen, fat and lean tissue, and energy expenditure adapts over time. For that reason, this phase does not use the estimate as a long-term weight forecast.
