People who are worried about gaining weight from the empty calories in booze might try to compensate by using diet soda when they make a seven-and-seven or a rum and Coke. But there's a catch that could land you in the drunk tank.
In a study published in 2013 in the journal Alcoholism: Clinical and Experimental Research, researchers from Northern Kentucky University reported that drinkers who consumed artificially sweetened mixers had a significantly higher breath-alcohol reading than those who used mixers containing sugar, which apparently slows the absorption of alcohol into the bloodstream. Worse yet, "individuals were unaware of these differences, a factor that may increase the safety risks associated with drinking alcohol," the scientists noted [sources:Marczinski and Stamates, Eldred].
