If two individuals drink the same amount of alcohol, the one with more muscle mass is likely to have what?

• A. Lower BAC levels due to faster metabolism
• B. No difference in BAC
• C. Higher BAC levels due to greater absorption
• D. It depends on weight

Answer: (C)

Alcohol distributes through the body's total water. More muscle mass adds more water overall, which expands the volume in which the alcohol can spread. With the same amount of alcohol, this larger distribution space dilutes the alcohol more, leading to a lower blood alcohol concentration (BAC). Metabolism by the liver runs at a relatively steady pace and is not driven by muscle mass, and absorption happens mainly in the stomach and intestines—not directly increased by having more muscle. So the idea is that extra muscle mass tends to lower BAC because of greater body water, not because alcohol is absorbed more quickly.
