A Calorie Calculator is a tool that estimates the number of calories a person needs to consume each day to maintain, lose, or gain weight based on their age, gender, weight, height, and activity level. The calculator takes into account the basal metabolic rate (BMR), which is the amount of energy expended by the body at rest to carry out basic physiological functions like breathing, circulating blood, and maintaining body temperature.
By using a calorie calculator, individuals can determine how many calories they should consume to achieve their weight goals, whether that be losing weight, maintaining their current weight, or gaining weight. The calculator can also help individuals track their daily calorie intake and adjust their diet accordingly to meet their goals.
