Get an Energy Boost From Grazing
"Eating consistently―three small meals with snacks in between―keeps your blood-sugar level even, so you don’t experience the highs and lows that occur when you go too long without food," says Molly Kimball, a registered dietitian at the Ochsner Clinic’s Elmwood Fitness Center, in New Orleans. Ideally, all your meals and snacks should contain complex carbohydrates (produce, whole grains) to provide fuel, and protein (nuts, cheese) to give you endurance. Try an apple and a piece of cheese or carrot sticks and edamame.
Snacks of refined carbs, like cookies and pretzels, provide an initial rush, but the body burns them quickly and your energy soon flags. To satiate a sweet tooth, try dark chocolate. It contains the chemical phenylethylamine, which increases energy by improving mood and attention span. According to Teitelbaum, dark chocolate also contains theobromine, a mild stimulant.
