Think about it: Have you ever met anyone who&amp;#39;s lost weight because she drinks diet soda? Though these soft drinks have no calories, they&amp;#39;re not doing your waistline any favors: Studies have repeatedly shown that people who down diet sodas have a greater chance of becoming obese. Why? &amp;quot;One theory says that because we taste something very sweet but don&amp;#39;t actually get the calories that go along with the sweet taste, we then go searching for those calories,&amp;quot; says Perrine. Plus, new research has shown that artificial sweeteners may in fact lower your metabolism. Drink water instead, and satisfy your desire for something sweet by eating fruit.
