You’ll get “hangry”
Cookie Studio/Shutterstock When you’re hungry, you’re also apt to get angry more easily, and so avoiding your morning meal may make you grumpy. This is especially true if you’re skipping breakfast because you’re in a rush, and not because you truly don’t feel like eating. One study from the United Kingdom showed that men who had eaten breakfast had a more positive mood at the start of the test session, and felt calmer afterward, than those who hadn’t eaten breakfast. Weston says the drop in blood sugar caused by skipping a meal causes irritability, along with fatigue and headache that can further worsen your mood. “Serotonin and dopamine, also known as neurotransmitters, are chemicals produced in the brain to regulate feelings and mood,” Weston says. “There is a connection between food intake and the balance of neurotransmitters produced by the brain. Skipping meals puts stress on the body and stress affects dopamine and serotonin levels.” On the flip side, eating regularly supports happy feelings.
Your energy will dip
Flamingo Images/Shutterstock Another reason skipping breakfast is linked to weight gain is that you have less energy for working out. If you’re feeling sluggish, you’re not going to want to hit the gym—and if you do, you may poop out in the middle of your session. Plus, once you finish a morning workout you’ll need to eat to refuel—so to get through the morning with a workout and no breakfast will leave you extra drained. According to information from the University of Wisconsin, breakfast should give you 25 percent of your daily energy, including high fiber and protein for fuel. If you don’t have time to cook eggs or make oatmeal, have a quick protein shake. Try some of these high-protein breakfast ideas.
Your breath stinks
Cookie Studio/Shutterstock Wait, how can not eating foods that could potentially give you bad breath still leave you with bad breath? U.S. News and World Report explains that eating breakfast stimulates saliva production and helps scrub your tongue of bacteria, which can make your morning breath more tolerable. Skipping breakfast ensures that stinky bacteria continue to thrive in your mouth. Dr. Mervyn Druian of the London Centre for Cosmetic Dentistry told DailyMail.com that the best fresh fruit and a glass of water is the most effective breakfast for washing away that bacteria.
