For example, a 100 pound man would typically have a BAC of 0.04 after one drink, whereas a 200 pound man might have a BAC of 0.02 after having the same drink.

This is why people who drink on an empty stomach will notice the effects of alcohol more quickly. Blood alcohol concentration (BAC) is the metric used in measuring how much alcohol is in your bloodstream. More specifically, BAC measures how much alcohol per 100 milliliters of blood.
