It's not just body weight that makes women more drunk than men on the same amount of alcohol. Research shows men and women of the same height and weight consuming the same amount of alcohol will metabolize it differently. Temple University Hospital cardiologist Sara Sirna said some of the reasons are natural. Women "have a larger proportion of body fat than men do and fat can't absorb the alcohol," she says. "So the alcohol actually concentrates and stays in the blood stream longer in women than it does for men."
