They are smaller on average than men and have a higher percentage of body fat, which means their bodies have less water to dilute the alcohol they drink – so their blood alcohol level rises faster. In 2017, Amie Haas of Palo Alto University in California found that women would routinely blackout with three fewer drinks than men.
