Final answer:
Alcohol can temporarily impact fat burn due to its effect on metabolism, but the duration depends on various factors.
Step-by-step explanation:
The effect of alcohol on fat burn depends on several factors, including an individual's metabolism, the amount of alcohol consumed, and other factors such as diet and exercise.
Alcohol is metabolized by the liver, and this process takes time. On average, it takes about 1 to 2 hours for the liver to metabolize one standard drink, which contains about 14 grams of pure alcohol.
During this time, the body's ability to burn fat may be temporarily reduced. However, it's important to note that alcohol itself contains calories, so consuming excessive amounts of alcohol can contribute to weight gain.
