The blood supply t o fat is much less than that found in muscles. Therefore, alcohol does not get metabolized as quickly in individuals with a higher fat content. When alcohol is metabolized, acetaldehyde, a poisonous byproduct, is formed. Alcohol dehydrogenase breaks down alcohol into acetaldehyde.
