Beer packs plenty of carbohydrates, so if you like the hops but not the belly flab, the bars you frequent may make a difference.

A new study, published in the journal Alcoholism: Clinical & Experimental Research, found patrons at bars with loud music drank beer more quickly and in fewer gulps. This study observed the golden target group of beer marketers -- males aged 18-25. When bar music went up, the average time it took to down a beer dropped from 14:51 minutes to 11:45 minutes. Patrons also ordered more drinks in a jammin' joint -- 3.4 versus 2.6.

Who knows why, researchers speculate less conversation may trigger more swigs. Choosing a quieter establishment may help you lose that beer belly and save your hearing.
