he tried-and-true advice for healthful eating also applies to keeping your energy level high: eat a balanced diet that includes a variety of unrefined carbohydrates, proteins, and fats, with an emphasis on vegetables, whole grains, and healthy oils. Taking a daily multivitamin will ensure that you get the vitamins and minerals you need, but taking extra amounts of individual nutrients won’t give you more energy. In addition, eating certain types of foods in particular amounts can help prevent fatigue.
Because different kinds of foods are converted to energy at different rates, some — such as candy and other simple sugars — can give you a quick lift, while others — such as whole grains and healthy unsaturated fats — supply the reserves you’ll need to draw on throughout the day. But limit the refined sugar and white starches to only occasional treats. While you may get a quick boost, that feeling fades quickly and can leave you depleted and craving more sweets.
