Have a Few Walnuts
If you're dragging, consider an unusual suspect: your liver. Thanks to the fatty, carb-heavy American diet, millions of adults are "increasing their odds of liver inflammation and putting themselves on the path toward cirrhosis—and they might never have touched a drink," says Jan Garavaglia, MD, host of the Discovery Health Channel's Dr. G: Medical Examiner and author of How Not to Die: Surprising Lessons on Living Longer, Safer, and Healthier from America's Favorite Medical Examiner. Fatigue and malaise are early symptoms of nonalcoholic fatty liver disease; to help prevent or reverse it, try eating an ounce of walnuts daily; they contain liver-healthy omega-3s. In general, try to replace junk food with fruit, vegetables, fish, and whole grains.
