95% of the alcohol you drink will be removed from your body by being burnt in the liver. Only about 5% will evaporate through your breath, urine and sweat.
How quickly will your body burn alcohol?
The rate at which your body burns alcohol is a personal trait that varies greatly between individuals. Everyone has a standard rate at which their body burns alcohol, and this cannot be accelerated by drinking coffee, exercising or having a sauna.
The most commonly used estimate is that alcohol burns at a rate of 1 gram per hour per 10 kilos of bodyweight. For example, an adult weighing 80 kilos would burn 8 grams of alcohol per hour, while an adult weighing 50 kilos would burn 5 grams of alcohol per hour. One serving of alcohol contains about 12 grams of alcohol.
Examples of alcohol burning rates for a 50 kg and 80 kg adult:
|Alcoholic beverage and volume||Alcohol servings||Estimated burning time, 80 kg adult||Estimated burning time, 50 kg adult|
|Beer class I, 0.33 l||0.5||< 1 h||1−1.5 h|
