The factors that can affect your blood alcohol concentration (BAC) include the amount of alcohol consumed, the time spent drinking, and body weight.

The amount of alcohol directly influences BAC; more drinks lead to higher concentrations of alcohol in the bloodstream. The time spent drinking plays a significant role because the body metabolizes alcohol at a roughly constant rate, meaning that longer drinking periods without breaks can lead to a higher BAC. Additionally, body weight is crucial because individuals with different body weights will process alcohol differently, with lighter individuals often experiencing a higher BAC than heavier individuals after consuming the same amount of alcohol.

While the type of drink consumed can influence how quickly alcohol enters the system due to factors like carbonation or added sugars, it is not the primary factor in determining BAC. The time of day might have some effect, particularly if a person is generally more fatigued, which can influence their tolerance and reaction to alcohol, but it is less directly related to BAC itself. Eating before or while drinking impacts how alcohol is absorbed but does not affect the fundamental relationships of quantity, time, and body weight in determining BAC levels.
