Week 3 Diet Update

Here's where I stand as of week 2:

Starting weight: 400.2 pounds on 11/16/2010
Current weight: 382.0 (as of 12/07/2010, 3 weeks into the diet)
Net Change (week): 3 pounds lost
Total Net change: 18.2 pounds lost
Goal: 300 pounds within 1 year (by 11/16/2011)

I'm scared I'm hitting a plateau here, as my rate of weight loss is decreasing. Still, I'm still losing, and that's good.
