How much should a 5ft 9 in 76 yr old man weigh?

For a 5-foot-9-inch tall man, a healthy weight typically falls within the range of 140 to 174 pounds, depending on body composition and overall health. The Body Mass Index (BMI) can be a helpful tool to assess weight relative to height; a BMI between 18.5 and 24.9 is considered normal. However, individual factors such as muscle mass, bone density, and health conditions should also be taken into account when determining an appropriate weight. It's best for the individual to consult with a healthcare professional for personalized guidance.
