How to use these estimates
Calculators are useful for a starting point, but they are not the finish line. Your real maintenance calories are revealed by logged intake, activity, and weight trend over a couple of weeks.
BurnFat uses the same principle inside the app: make a reasonable estimate, log meals quickly, then adjust from real trend data instead of chasing a perfect formula.
Turn the calculator into a daily feedback loop.
BurnFat connects meal logging, activity, and calorie balance so the number becomes a trend you can actually follow.
