a protruding potbelly caused by excessive drinking of beer.
“In one of the less surprising revelations of the year,
researchers at the University of North Carolina (UNC) and
colleagues have confirmed that excessive consumption of beer
can lead to the condition commonly known as beer belly. At
the same time, however, they discovered that, beyond aesthetic
concerns, the condition may point to health hazards of a more
serious nature. In a comparison of beer drinkers and wine
drinkers, the scientists found that beer tends to build a
central paunch, or “potbelly”, while wine drinkers tend to
have narrower waists, even when the same amount of alcohol and
calories is consumed by both.”
