Okay, So I am 20 yrs old, and im trying to make that transition from eating like a little kid to eating healthy foods. I work a lot of hours and weekends are crazy. I do a normal full time job M-F and get my 3 meals a day. I started changing my breakfast from donuts to frosted mini-wheats, but im not sure if its any better for me. And for lunch i eat PB & J along with chips, cookies, or wheat thins. Dinner for M-Thurs is almost always a home cooked meal. But on friday nights im lucky if i have time to grab some donuts between my full time and part time job! And then saturdays i eat pizza, donuts, etc. AKA JUNK!! same for sundays... I'm always tired and i think its because i eat all sugary foods!! i am a very picky eater too, which doesnt help!! Does anyone have any advise as to what's healthy and whats not..I just dont wanna be 40yrs old and have clogged arteries!!!
