Welcome to our Calorie Calculator. This calculator operates using the Mifflin-St Jeor Equation which is considered the most accurate equation for calculating BMR. You share info about yourself, we do some math magic to find out how many calories your body needs, and then we hand you a magic number. Stick under it for weight loss, around it for maintenance, or go a bit over for some gains. It’s like having a personal calorie roadmap to reach your fitness goals!
