The most fattening cocktails - Forbes.com

After a night of drinking cocktails, most people will not only wake up the next morning with a screaming hangover, they'll wake up fatter too.

That's because the average serving of one ounce of 80-proof alcohol contains about 90 calories. And that's before mixers are added. While many people who spend hours on treadmills or yoga mats may smugly eschew dessert or ban butter from their diets, often they will happily consume a cocktail--or three--without giving it a second thought. But they do so at considerable peril to their waistlines. A Pina Colada, for example, has more calories than a Big Mac.
