常见问题

Quick answers.

›What is the Mifflin-St Jeor equation?

It is a formula used to calculate your resting metabolic rate (RMR) based on age, sex, height, and weight. It is widely considered to be one of the most accurate predictive equations for weight management.

›How is activity level factored in?

The calculator applies a Physical Activity Level (PAL) multiplier to your basal metabolic rate. This ranges from 'Sedentary' for office work to 'Extra Active' for intense physical labour or twice-daily training.

›Is my health data private?

Yes. All calculations are performed on your device using client-side logic. Your height, weight, and age are never uploaded to a server.

›How many calories are needed for weight loss?

A typical deficit for sustainable weight loss is 500 calories below your TDEE. This calculator provides specific targets for both 'Weight Loss' and 'Aggressive Weight Loss' based on your profile.
