What aspect of health does the target body weight formula primarily focus on?

The target body weight formula primarily focuses on fat weight changes, as it is designed to help individuals determine an appropriate body weight that reflects a healthy level of body fat. The formula considers various factors, including height, age, gender, and body composition goals, to estimate an ideal weight while prioritizing fat loss or maintenance.

This focus on fat weight changes is crucial because excessive body fat is associated with various health risks, including obesity, diabetes, and cardiovascular diseases. By targeting fat weight, individuals can achieve improved health outcomes and optimize their body composition, which is essential for overall wellbeing.

In contrast, the other answer choices address different aspects of fitness and health that are not the primary focus of the target body weight formula. For instance, bone density improvement pertains to skeletal health rather than weight composition itself. Cardiovascular endurance is a measure of aerobic fitness, and flexibility enhancement relates to the range of motion in joints—all of which may be important for overall health but do not directly relate to the calculations involved in determining target body weight based on fat levels.
