About this calorie calculator
The calorie calculator is based on the Mifflin-St. Jeor equation is a widely accepted formula developed in 1990 to estimate an individual's Basal Metabolic Rate (BMR), which is the amount of energy (calories) the body burns while at complete rest. It is often considered the most accurate and reliable BMR calculation for a broad range of adults, including both non-obese and obese individuals, generally outperforming older equations like the Harris-Benedict. To function as a "daily calculator," this equation is the essential first step. The resulting BMR figure is multiplied by an activity factor—ranging from sedentary to extra active—to estimate a person's Total Daily Energy Expenditure (TDEE), or the total calories needed to maintain their current weight.
