Who the fuck told you poptarts, pretzels, and pb&j are good meals?
MAYBE PB&J if the peanut butter and jelly are natural and it's on whole grain bread, but poptarts? PRETZELS?!
GO BUY CHICKEN BREASTS
GO BUY HEADS OF BROCCOLI
GO BUY SPINACH
GO BUY NUTS
GO BUY OLIVE OIL
PUT THE ABOVE INTO A MASSIVE SALAD AND EAT 1/3 early in the school day, 1/3 ~4 hours later and 1/3 ~ 3 hours after that. Of course this is considering you ate a solid eggwhite&spinach omlette and oatmeal for breakfast.
If you are too lazy to make a real man's salad jsut drink a good , complete protein shake.
POPTARTS LOL still laughing at that one.
