Everyone’s favorite choice for energy is caffeine. Your options include coffee, tea, soda and performance beverages formulated for pre-workout use. Nutrient savvy athletes recognize carbohydrates as a reliable source of lasting energy, especially if you go with slowly digested complex carbs from sources like sweet potato, asparagus and brown rice. A study published in the journalSLEEP explored the impact of fats on energy.
According to researchers, protein didn’t affect energy levels, but fat consumption can decrease energy and alertness regardless of your age, gender, amount of daily caloric intake or body weight. A study of 31 healthy subjects aged 18 to 65 showed that fat consumption can weigh heavily on sleepiness even if you enjoyed a solid 8 hours of sound slumber the night before. Of course, your body needs healthy fats for a variety of functions. The trick is to avoid over-consumption.
