Which formula does it use?

Mifflin–St Jeor, multiplied by a standard activity level. It is a good estimate for most adults, but real needs vary.

What do BMR and TDEE mean?

BMR is what your body burns at complete rest. TDEE adds your daily activity, so it is roughly what keeps your weight steady.

Calories at rest (BMR) and a day’s total (TDEE), and how much to eat to lose or gain weight.

Example: a woman of 25, 60 kg and 165 cm, moderately active: 1,345 kcal at rest and about 2,085 kcal a day to keep her weight.
