Breakfast gives you the energy you need to get things done and helps you focus at school. Many studies have linked eating breakfast to good health, including better memory and concentration, lower levels of “bad” cholesterol, and lower chances of getting diabetes, heart disease, and being overweight. It’s hard to know, though, if breakfast causes these healthy habits or if people who eat it have healthier lifestyles. But this much is clear: Skipping the morning meal can throw off your body’s rhythm of fasting and eating. When you wake up, the blood sugar your body needs to make your muscles and brain work their best is usually low. Breakfast helps replenish it. Many of us skip breakfast because they’re rushing to get out the door. That’s a mistake. You need food in your system long before lunchtime. If you don’t eat first thing, you may get so hungry later on that you snack on high-fat, high-sugar foods and then focussing at school is even more impossible!
