The Mifflin-St Jeor formula: it is more accurate than the older Harris-Benedict one and is recommended by dietetic associations. First the basal metabolic rate is calculated (what the body burns at rest), then it is multiplied by an activity factor.
A common guide is 500 kcal a day below maintenance, which is about 0.5 kg a week. Going below 1200 kcal for women and 1500 for men without a doctor is not advisable.
The formula gives the average for people with your parameters; the spread can be ±10%. Track your weight for 2-3 weeks and adjust the figure to yourself. With medical conditions or pregnancy, see a doctor.
