It is unhealthy if the fat content of an adult male drops below 3% or 8%.

To determine if the fat content of an adult male is unhealthy, we need to consider the ideal range of body fat percentage for men. The ideal range can vary depending on factors such as age and overall health, but generally, it is recommended that adult males have a body fat percentage between 10-20%.

From the values you provided (12, 24, 20, 3, 8), we can see that only the last value, 3, falls below the recommended range. A body fat percentage as low as 3% in an adult male is generally considered unhealthy and can be a sign of malnutrition, muscle wasting, or an underlying health condition.

If an adult male's body fat percentage consistently falls below the recommended range, it is important to consult with a healthcare professional to determine the underlying cause and develop a suitable plan to address the issue.
