Can you tell me the normal BMI range for 65-70-year-old men?
The BMI score is “subjective” to some, while too “objective” to others. Based on the medical studies, adults with a BMI below 18.5 and above 24.9 had more weight-related medical issues. Therefore, they “objectively” decided that 18.5–24.9 was “normal.” But for seniors, it’s not so easy to “objectively” decide a “normal” range.
One of the most notable effects of age is the involuntary loss of muscle mass, resilience, and function.
Muscle mass drops approximately 3–8% after the age of 30, and this rate is even higher after the age of 60. So, the “normal” BMI scale for a 70-year-old guy who has lost much muscle weight is different from an active guy who has lost very little. This is where the “subjective” part comes in. So you might “subjectively” decide on a good BMI on your own or ask a doctor to make an “objective” judgment for you based on the amount of muscle loss you’ve had.
