Which equation is most applicable for predicting the caloric needs of male athletes and the general population?

The Harris-Benedict Equation is a classic formula widely used for estimating caloric needs in both the general population and athletes, particularly males. It takes into account the individual's basal metabolic rate (BMR) and adjusts it based on activity level, making it suitable for a diverse group of people. This equation has been historically recognized for its ease of use and adaptability, which allows it to serve as a first step in determining total daily energy expenditure.

While there are other equations available, such as the Cunningham Lean Mass Equation, which is particularly tailored for athletes focusing on lean body mass, the Harris-Benedict Equation's broader applicability to various populations, including both active and sedentary individuals, solidifies its relevance for estimating caloric needs across different groups. The use of factors like sex, age, weight, and height in this equation provides a comprehensive assessment that can be applied universally to male athletes and the general population alike.
