How the Calorie Calculator Works
This calculator estimates your Basal Metabolic Rate (BMR) using the Mifflin-St Jeor equation, then multiplies it by an activity factor to estimate total daily calories needed to maintain your current weight.
Formula Used
Men: BMR = 10W + 6.25H − 5A + 5
Women: BMR = 10W + 6.25H − 5A − 161
W = weight in kg, H = height in cm, A = age in years. Maintenance calories = BMR × activity factor.
Practical Use
A deficit of about 500 calories/day leads to roughly 0.5 kg (1 lb) of weight loss per week. Use the ranges above as a starting point and adjust based on real-world progress.
