Just as a car runs more efficiently with cleaner fuel, your body works best with specific foods. The healthier and more nutrient-rich your diet is, the more energy you’ll have. Some foods that give you more energy are vegetables (especially leafy greens), chia seeds, fiber-rich foods, whole grains, and high-protein foods. Sugary and processed foods may give you a temporary burst of energy, but you’ll soon crash. It’s best to avoid them in the mornings. An energy-optimized diet also includes drinking lots of water, since dehydration is a common cause of low energy.
