Tips for a healthy lifestyle?

I am very very unhealthy. I eat fast food pretty much on a daily basis (i have a Taco Bell and Jack in the Box right across from my house and those are the only food places I can go to since I live too far from everything else) and when I don't eat fast food I am eating junk at home. I get constipated often ( i know but needed information i think) I am always tired and feel gross all the time.
