The Alternate: Get the sweet taste you crave, as well as a stronger jolt of energy, by pouring brewed coffee over ice cubes and adding 2 Tbsp. fat-free half-and-half and 1 packet sugar (31 calories, 4g sugar, 95–200mg caffeine).
Even Healthier: Gensler's all-natural ice tea spritzer refreshes with even fewer calories. Brew 1 cup of caffeinated tea and chill, then add 1 cup of unflavored seltzer, 1 teaspoon lemon juice, 2 fresh mint leaves and 1/2 teaspoon honey (15 calories, 9g sugar, 14–61mg caffeine). The honey adds more calories than sugar does but also more antioxidants.
