Which of the following methods can help reduce alcohol consumption?

Setting a drink limit ahead of time is an effective strategy for reducing alcohol consumption because it encourages individuals to plan and monitor their drinking behavior before they start consuming alcohol. By establishing a specific limit, a person can better control their intake, avoid overindulgence, and make more deliberate choices throughout the event. This proactive approach not only promotes mindfulness regarding alcohol consumption but also helps in maintaining better overall awareness of one's limits and the effects of alcohol.

In comparison, drinking on an empty stomach can lead to quicker intoxication and is not a method to reduce alcohol consumption; rather, it can have the opposite effect. Participating in drinking games often encourages excessive drinking in a social setting, which can lead to increased consumption rather than moderation. Mixing alcohol with energy drinks can mask the effects of alcohol, leading individuals to drink more than they otherwise would without feeling the full impact, thus potentially increasing total consumption.
