The biggest problem with low-carb diets is they restrict your body's
preferred energy source. If you want to cut back on calories from
carbohydrates, focus on reducing your intake of soft drinks, candy
and other foods with added sugars. To maximize your energy level
and your long-term health, look to nutrient-rich carbohydrates. Enjoy
the great taste of whole and fortified grains (6 to 7 servings per day,
at least half of them fiber-rich whole grains). Also eat fruits (2 cups)
and vegetables (2 ½ cups) every day.
