Your enzymes prepare the alcohol to be eliminated later on by metabolizing it. Individuals with a higher body weight tend to have a higher metabolism rate, which means they can process alcohol faster than those with a lower body weight. As a result, their breath may show lower levels of alcohol compared to someone with a smaller build who has consumed the same amount.
