Hello to all!

I am a 22 year old male who has weighed about the same weight the past few years. Until recently, it hasn't bothered me (well, about the last year or so). I have tried to act on it a few times, but lacked the discipline. I now have the discipline and drive to do this the healthy way. Here is more about me...

I'm 22, male, 5 foot 6" and I weigh 160ish lbs. I used to weigh 140 lbs in high school and was thin then. I am not extremely obeise at all; I am considered "chubby". I want to lose the weight to be in better shape and I want to start excercising more. My problem is with fast food and I must be honest. I eat at a fast food restaurant every single day for lunch. I have the past year. I always tell myself no I won't eat nothing bad for me today and sure enough I am at the local Chipotle, Wahoo's Fish Taco, or any other to go fried food place ready to order. I want to stop. I also have a double chin when I push my chin against my neck and it drives me crazy. I am dislike my chubby cheeks as well.

What would would you guys recommend for a substitute lunch that is much healthier. What about the Jared diet? I was thinking that this would be the best thing as these Subways are everywhere. Any healthy fast food selections??!? I really would like to lose this weight. I have been drinking alot too since I turned 21. Every weekend I binge drink. I am willing to stop though for the cause...

I REALLY REALLY WANT TO MAKE THE EFFORT AND AM WILLING TO STOP DRINKING AND FAST FOODING!!

ANY POINTERS??!? GOOD DIET SUGGESTIONS?!? and STRATEGIES?!?I don't want to over due it either. I believe I have over done it when I tryed to diet and got burned out and stopped in the past. Not this time. I want a 6-pack!? : )
