Margaritas may be a tasty accompaniment to your tacos or enchiladas, but these are among the highest-calorie alcoholic beverages you can choose. Laced with sugar and sweet liqueur, just one margarita may contain as many calories as your meal. The actual count will vary by recipe, and you can create a much lighter version with some key ingredient substitutions.
Eight ounces of a standard margarita on the rocks will set you back about 455 calories, while a 12-ounce margarita has about 680 calories. You can lighten up your drink by limiting the Cointreau -- or triple-sec, which is sometimes used instead -- and by using fresh lime juice instead of a sweetened version. Omit sweet-and-sour syrup and sugar, and use just one ounce of tequila to further reduce calories. If your drink seems too small, add come zero-calorie soda water.
