Estimate is not diagnosis
BMI, BMR and TDEE use formulas or population references. They may guide general understanding, but they do not assess clinical history, lab results, medication or individual context.
How to interpret better
Use results as a reference range and compare trends over time. For clinical goals, pregnancy, lactation, illness, childhood or adolescence, seek professional guidance.
The best use is educational: understand the formula, see the limits and avoid health decisions based on a single number.
