For a man who is 5'9", what is his ideal body weight?

To determine the ideal body weight for a man who is 5'9", the most commonly used method is the Devine formula, which provides a standard way to calculate ideal body weight based on height. According to the Devine formula, the ideal body weight for men is calculated as follows:

1. The first 5 feet (60 inches) contributes 50 kg (110 lb).

2. For each additional inch, add 2.3 kg (5 lb).

In this case, for a man who is 5 feet 9 inches tall, we calculate his ideal body weight as follows:

• Begin with 50 kg for the first 5 feet.

• The additional 9 inches corresponds to 9 x 2.3 kg, which equals 20.7 kg.

Combining these, 50 kg + 20.7 kg equals 70.7 kg, which is approximately 155.5 lb.

Thus, this method validates that the ideal body weight for a man at this height is indeed 70.7 kg (155.5 lb).
