Calculate your Basal Metabolic Rate — the calories your body needs at complete rest.
The Mifflin-St Jeor equation is the most accurate BMR formula. BMR represents the calories needed for basic life-sustaining functions at rest.
Weight contribution
10 × 70 kg
= 700
Height contribution
6.25 × 170 cm
= 1,062.5
Age adjustment
−5 × 30 years
= −150
Gender adjustment
Male: +5 | Female: −161
= +5
Total BMR
700 + 1,062.5 − 150 + 5
= 1,618 cal/day
