What factors affect BAC (Blood Alcohol Concentration)?

Blood Alcohol Concentration (BAC) is influenced by a combination of physiological and situational factors. Body weight and body fat play a significant role because alcohol is distributed in body water, and individuals with a higher body fat percentage and lower water content tend to have higher BAC levels for the same amount of alcohol consumed.

Additionally, the amount of food in the stomach can affect BAC levels as well. Consuming food before or while drinking alcohol can slow the absorption of alcohol into the bloodstream, leading to a lower BAC. The actual alcohol consumed—its quantity and strength—directly affects BAC, with higher amounts resulting in higher concentrations.

Thus, considering all these elements, it becomes clear that multiple factors are at play in determining BAC levels, which justifies the choice that encompasses all these aspects.
