Calorie intake calculation using body mass index (BMI) is a mathematical equation that determines an individual’s daily caloric needs based on their weight and height, which are parameters used in BMI calculation.
Knowing how to calculate calorie intake with BMI is essential for setting realistic weight management goals. It provides a starting point for determining the amount of calories needed to maintain a healthy weight or to lose or gain weight. The concept of using BMI to estimate calorie intake dates back to the 1970s, when it was first proposed by Ancel Keys, a leading researcher in the field of obesity.
