Skinny Piña Colada: 229 Calories

Rum that's infused with a coconut flavor can cut about 300 calories from a piña colada. What's out? The sugary, coconut milk mix. Measure one shot of coconut rum. Then add fresh strawberries, a splash of agave syrup, and blend with ice. You get a tall, 12-ounce tropical cocktail for about the same calories as in a handful of pretzel twists.
