To estimate caloric intake for weight loss, body weight should be multiplied by which number before subtracting?

To estimate caloric intake for weight loss, body weight is multiplied by 10 to 15, depending on various factors such as age, sex, and activity level, before subtracting from the total. However, the more commonly accepted baseline for an average estimation in many dietary practices is the figure of 15. This number is typically used because it provides a balanced approach that considers the caloric needs of an individual while still allowing for a caloric deficit necessary for weight loss. Multiplying body weight by 15 helps in calculating a calorie goal that reflects basal metabolic rate (BMR) while accounting for daily activity levels, thus making it a practical starting point for weight loss plans.

The other figures, while they could potentially be used in certain contexts or for specific individuals based on varying activity levels or specific dietary goals, do not have the same baseline applicability for general weight loss estimations.
