Frequently Asked Questions
How are daily calories calculated?
We use the Mifflin-St Jeor equation, considered the most accurate for most people. BMR is calculated from your age, weight, height, and gender, then multiplied by an activity factor.
What is BMR?
Basal Metabolic Rate (BMR) is the number of calories your body burns at complete rest — just to keep you alive. It accounts for breathing, circulation, and cell production.
How many calories should I eat to lose weight?
A deficit of 500 calories per day typically results in about 0.5 kg (1 lb) of weight loss per week. Avoid going below 1,200 calories (women) or 1,500 calories (men) without medical supervision.
Is the calorie calculator accurate?
The Mifflin-St Jeor formula provides a good estimate for most people, but individual metabolism varies. Use the result as a starting point and adjust based on real-world results over 2–3 weeks.
