The Mayo Clinic provides a BMI calculator that can be used to determine the ideal weight range for healthy adult men. This calculator takes into account height, weight, sex and age to calculate an accurate body mass index rating.
The BMI range considered healthy for adult males is 18.5 to 24.9. While there is no ideal weight for a healthy adult male, healthy height-to-weight ratios can provide a starting point for evaluating health and determining a healthy weight range for an individual. Furthermore, the Mayo Clinic calculator provides advice on altering lifestyle habits to achieve a more desirable BMI rating.
