If you start off slow....

I'd agree on the protein and carbs.  Getting the protein in hasn't been hard.  I use Jay Robb and unjury.  I was very slow losing on WW.  30lbs in 9 months and the last three months were stagnant or 1/2 lb here and there.  It was hard to get there and unsustainable.  (even with excercise) 

It wasn't always like this, but since being diagnosed with diabetes and metabolic syndrome, I  do think that has a lot to do with how fast people lose.  As long as I get there in the end, I'll be fine. 

You'll get there.  I honestly believe that the longer it takes you the more you learn along the way to help you maintain after.

You're doing great. Although everyone is different,  I was about where you are at 6 weeks.  I spend many weeks with 1/2 to 1 lb weight loss, and every once in a while drop a bunch more.  Right now, I seem to be losing more quickly, but I recently started more strength training, so perhaps that is helping.  I'm sure I'll be back to my "regular" trend soon.
