The impact of body weight on alcohol metabolism varies between light and heavy individuals, and it is primarily influenced by the amount of alcohol-metabolizing enzymes present in the liver [1].

In general, people with a higher body weight have a larger volume of liver tissue, which can potentially accommodate more alcohol-metabolizing enzymes [2]. This means that heavy individuals may metabolize alcohol at a faster rate than lighter individuals, as they have a greater quantity of enzymes available to break down alcohol [3].

However, it is important to note that the rate of alcohol metabolism can also be affected by other factors, such as age, gender, genetics, and the presence of other substances in the body [4]. For instance, women generally have less alcohol-metabolizing enzymes than men, which can lead to a slower rate of alcohol metabolism in women compared to men [5].

In addition, chronic alcohol consumption can lead to a decrease in the efficiency of alcohol metabolism, as the liver may become damaged and unable to effectively process alcohol [6]. This can result in a buildup of alcohol in the body, leading to increased levels of intoxication and potential health complications [7].

In conclusion, body weight can impact alcohol metabolism, but it is only one of several factors that can influence the rate at which alcohol is processed by the body. Other factors, such as age, gender, genetics, and the presence of other substances, can also play a significant role in alcohol metabolism [8].
