Naturally flavored seltzer
If you're bored with plain old water, try naturally-flavored seltzer — carbonated water with a shot of fruit flavor. It's completely calorie-free, fizzes like soda, and comes in fun flavors like green apple, cherry, pomegranate… even vanilla and white chocolate! And it's one of the "cleanest" drinks around — it doesn't contain sugar, artificial sweeteners
, food dyes, or anything else. For sweetness and pizzazz, float a few fruit slices or frozen fruit cubes made with 100% juice in your glass.
