A can of Coke here, a latte there — all those liquid calories really start to add up. Stick to nature's beverage, and sip water throughout your day not only to stay hydrated, but to help you feel full. Plain water too boring? Spruce it up by squeezing in some lemon or lime juice, brew some herbal tea, or enjoy sparkling water instead. And while fresh fruit juices are healthier than a soda, they're still high in calories. You're better off eating an orange or slices of fresh pineapple to get your fruit fix as well as some much-needed fiber.
