What a calculator can and cannot tell you

Every tool here runs a formula built from population averages. That makes them useful for orientation and useless as a diagnosis. Two people with identical inputs can differ by hundreds of calories a day in real expenditure, and BMI cannot distinguish muscle from fat at all.

Use the numbers as a starting hypothesis, then correct them against what your body actually does over three or four weeks. Your own data beats any equation within a month.

None of this is medical advice, and none of it can see your blood work. If you want a clinician to look at the numbers that actually describe metabolic health, that is what our intake is for.
