Why this exists
Body mass index only compares height and weight. This page turns the same body into a day’s calories with the Mifflin–St Jeor equation. Two people at 60 kg can land on different numbers once age and movement change.
It is not a clinic and not a meal plan. Change the sample age and the activity until the table matches the week you actually live.
