Your Basal Metabolic Rate is the energy your body uses at complete rest just to keep you alive.

The math behind it

Mifflin–St Jeor: BMR = 10 × kg + 6.25 × cm − 5 × age + 5 (men) or − 161 (women).

Male, 70 kg, 175 cm, 30 yrs → 700 + 1,093.75 − 150 + 5 = 1,649 kcal/day.

BMR vs TDEE?

BMR is rest-only; TDEE multiplies BMR by an activity factor to include daily movement and exercise.
