Think skipping dinner in favor of happy hour will save you calories? Not unless you do it right! So you want to savor a drink but don't want to pack on pounds? With these swaps, you can have your vodka and drink it too! Say your favorite cocktail is a rum and coke. Say hello to 189 calories-per drink! A better bet? Swap full-calorie mixers with diet soda or tonic. You'll save almost 100 calories a glass. So say you want two beers (it's happy hour!) You could have two regular drafts, and down 384 caloriesor two light beers at 288 calories. As for a best everyday drink, stick to a 12 ounce bottle of light beer, or a 4 ounce glass of wine, both of which have 100 calories. But take note that standard wineglasses hold twice that amount. While these drink swaps will save you calories, we don't recommend skipping dinner in favor of happy hour-that's just a recipe for many UN-happy hours later!
