FACT: A diet rich in carbohydrates—particularly high-fiber items, such as fruits, vegetables and whole grains—is essential. Carbs are the body’s ideal fuel source, and getting adequate amounts ensures sufficient energy for daily physical activity, metabolic functions and repair. People who avoid carbs while dieting need to resort to an alternate, less- efficient energy source.
“It’s best to aim for 50%–60% of total calories from carbohydrates for optimal health,” says Cynthia Sass, MPH, MA, RD, LD, author of Your Diet Is Driving Me Crazy (Marlowe & Co. 2004). Limiting carbs often results in headaches, poor endurance, muscle tissue breakdown and dehydration, she explains.
