How it works and good to know
The default formula is Mifflin-St Jeor (1990), and you can switch to the revised Harris-Benedict equation (1984). Daily calories burned (TDEE) is BMR multiplied by an activity factor of 1.2–1.9. Calorie targets estimate 1 kg of body fat as about 7,700 kcal and show losing 0.25 or 0.5 kg a week, maintaining, and gaining 0.25 kg a week; targets below 1,200 kcal for women, 1,500 kcal for men, or below your BMR are flagged. These are reference values for adults aged 15–100 and don’t replace medical or nutrition advice.
