The term refers to a tool, often an online calculator or formula, utilized to estimate an individual’s basal metabolic rate (BMR). BMR is the amount of energy, measured in calories, the body requires at rest to maintain basic life functions. For example, an individual could input their age, sex, height, and weight into such a calculator to receive an estimated BMR value.
These estimations are significant because they provide a baseline for determining daily caloric needs. This baseline is valuable in weight management strategies, informing individuals about the caloric intake necessary for weight loss, maintenance, or gain. Historically, the initial formulas were developed to provide a standardized method for calculating these estimations, contributing to advancements in nutrition science and personalized dietary planning.
