Obviously, you'll save calories when you stop adding sugar or honey to your coffee, cereal, oatmeal, and other foods. However, substituting artificial for real may not be the answer either: Some studies suggest that drinking diet sodas and eating foods with artificial sweeteners also increase the risk of being overweight. Artificially sweetened foods may not have the calories of sugar-sweetened foods, but they keep sweetness on our taste buds and our minds. Plus, some artificially sweetened candies and foods contain sugar alcohols such as sorbitol, which can cause gassiness and bloating in sensitive individuals. So, refusing to satisfy your sweet tooth with sugar — real or fake — can be doubly effective at flattening your belly!
