I don't know if that was just shorthand or whatever, but don't only workout your quadriceps, hit the whole leg. And don't forget to hit your abs either (important for back health

)
I would do more cardio work, cardio will help with your metabolism, it also has an appetite suppressing effect (I know this for a fact, I'm not blowing smoke.)
One more thing, and this is just my opinion with which some may disagree. I would do "quads and chest" on one day and weird combos like that because you're going to have a hard time working out your chest without your arms. Following that you have back day, which again, requires arms, followed by arm day, which won't be very dramatic after 2 days of good upper body conditioning.
I like your drive and enthusiasm, that'll get you results.
