What does blood alcohol content (BAC) NOT depend on?

Blood alcohol content (BAC) is a measurement of the amount of alcohol present in a person’s bloodstream, expressed as a percentage. It is influenced by various factors, but physical fitness is not one of them. The primary factors that determine BAC include body weight, the amount of alcohol consumed, and the time frame over which the alcohol is consumed.

Your body weight plays a significant role in BAC calculations because a heavier person generally has more body fluid to dilute alcohol, resulting in a lower BAC compared to someone lighter who drinks the same amount. Similarly, the total amount of alcohol consumed directly correlates with BAC; the more alcohol one drinks, the higher the BAC will be. The time between drinks is also crucial, as the liver metabolizes alcohol over time; drinking rapidly can lead to a higher BAC than consuming drinks more slowly.

While physical fitness may affect how well a person feels or their endurance, it does not directly influence the rate at which alcohol is processed in the body or the resulting BAC level. Therefore, the correct response highlights that physical fitness is not a determining factor in assessing BAC.
