A healthy weight range can be assessed using the body mass index (BMI), which considers an individual's weight and height. A BMI between 18.5 and 24.9 is typically classified as normal weight. Besides BMI, other factors like muscle mass, bone density, and distribution of body fat are important for evaluating health. Tools like waist circumference can also aid in determining healthy weight by assessing visceral fat, which is linked to higher health risks. Regularly checking these metrics helps individuals maintain a healthy weight.
