Junk food is yummy but sneaky. It may fill your tummy quickly, but it can also make you lazy, tired, and moody. That’s because it’s high in sugar and bad fats, which give quick energy and then cause a sudden drop. This affects your mood and brain power. Eating junk too often can lead to headaches, bad sleep, and poor concentration. For a happier body and brain, try fruits, nuts, and homemade snacks. They’re your super fuel!
