Is it necessary to have breakfast everyday. i live in the hostel so since i wake up hostel, i often miss breakfast. is that cool?

It's not cool: Missing breakfast is a sure way to develop weight gain problems. Break the fast!

Most impt meal of da: Just like your grandma told you. Jump starts your metabolism, provides calories, protein for your brain to use (maybe with less caffeine); prevents overeating later in the day. Studies confirm better test scores and work output in people who eat breakfast. Also better success with weight loss and weight maintenance.
