How this is calculated
Resting burn uses the Mifflin-St Jeor equation (Mifflin et al., 1990): 10 x weight (kg) + 6.25 x height (cm) - 5 x age, then + 5 for men or - 161 for women. Maintenance multiplies that by a standard activity factor from 1.2 to 1.9. The deficits subtract 250 or 500 calories a day, based on the long-used approximation that about 3,500 calories equals one pound of body fat. Real results vary. The range line converts the WHO BMI cutoffs into weights for your height. If you choose Other / prefer not to say, the sex-based part uses the average of the male and female equations.
