Shochu Cosmo: 70 Calories

Make a super-slim cosmopolitan by replacing the vodka with shochu, a Japanese spirit with a smooth flavor. A 2-ounce serving has only about 35 calories. Add splashes of diet cranberry juice, fresh lime juice, and orange juice, and then toss in a martini shaker. This cosmo shakes out at half the calories of a traditional cosmopolitan.
