Your diet is really clean man, I'm impressed. Don't starve yourself though. You can't expect all the weight to come off immediately, and a lot of times people go so hard they burn themselves out and just give up. Take some days off too in there. You need a rest day every few days. The one change I would make to your diet is to eat another small meal about an hour before your boxing b/c you go without anything for 6 1/2 hours.
The soreness should go away as you build strength. Those first few weeks are tough though. You have a pretty serious routine for a newbie too, so being sore comes with the territory. If it doesn't get better or start to decrease, then there may be something wrong there, but in all liklihood, it's "good" soreness.
