You need to fuel your brain throughout the day with nutritious food. Skipping meals can have numerous negative effects on your healthy lifestyle. Going without food for too long can make you so hungry that you overeat at your next eating opportunity, and you likely won’t eat as healthfully as you would have otherwise. Skipping meals can negatively affect your productivity, concentration, and energy level. Since your brain runs on glucose, not giving it enough makes you lose your ability to focus. If you go without for a long time, your brain basically stops being able to do anything but think about how hungry you are. Plus, your mood turns nasty. “Hangry” much? So make time and even schedule eating opportunities throughout the day.
