Don't slack on sipping Of course, you have a water bottle Velcro'd to your bod in the summer when you're sweating bullets. Odds are you're not always thinking about hydrating in the winter, however. The fact is, cold-weather activities and indoor heat can leave your body parched. When your body is crying out for fluids, you can also mistakenly interpret the message as hunger and end up eating too many calories, says Eliot.
To make sure she gets enough fluids in the winter (ladies over 19 years old need about 2.7 liters a day), Eliot lays down her H2O goals: "When I'm at work, I fill a 16-ounce cup with water twice in the morning. I don't allow myself to head to lunch before I've finished the two cups. Then, I can't leave in the evening without having two more cupfuls. This really keeps me from feeling ravenous later in the day." To chase away chills and stay hydrated, Blatner loves hot green tea, which she points out, research says may potentially boost metabolism too.
