Different formulas were developed for various populations and purposes. Viewing multiple results gives you a healthy weight range rather than a single number.
People with larger frames naturally carry more weight in bone and muscle structure, so their ideal weight range is higher than those with smaller frames.
Ideal weight is a guideline. Healthy weight depends on many factors including muscle mass, bone density, and overall health markers.
Athletes with high muscle mass may fall outside typical ranges. Body composition analysis is more useful for athletic populations.
