I wouldn't have been allowed to progress that fast, but if your plan allows it, then who am I to say?
Be careful, though. It takes real commitment to get to your goal, and a lot of people never make it. I would stick to my clinic's plan as closely as possible. The first few weeks and months are the easiest times to lose weight - it gets progressively harder the further out you get. Don't blow your big chance. There will be plenty of time to enjoy your favorite foods (in moderation, of course) later.
