Non-alcoholic beer was born in the need to drink alcohol without all the calories. It's not just for people who can't drink or don't want to – there are plenty of reasons to occasionally enjoy this brew. For instance, it's an economical and refreshing way to guard against getting too tipsy and throwing up after a night of drinking. Supermarkets offer 100 calorie beers that satisfy both thirst & your need for an alcoholic buzz without all those pesky calories!
It helps if you're on medication that makes it unsafe for you to drink normally, but even then some medications won't conflict with low-calorie beer since they are not metabolized by the liver like regular alcohol is made singlehandedly by the liver.
