Stuck so early out?

I've been on many diets in the past and accustomed to plateauing, weight shifting day to day, etc. but I think this is a little strange...I haven't lost anything since 2.5 weeks and am now 4.5 weeks out. I'm strictly adhering to the plan, I walk briskly for 60 mins a day (as much as I can handle), get in my fluids and protein, no carbs, etc. not losing any inches either...I started at 306 pre-op, was 299 on operating day, and am now stuck at 281 for over 2 weeks (so 18 lbs. lost since surgery)...I know I know I know, it will start back up again, but I'm definitely no lightweight and with all the modifications I guess I just expected more...Ok pity fest over!!

You are in the dreaded three week stall.  AND IT SUCKS!!!  It sucks to watch the weight fly off the body and the scale plummet for 2 weeks, then NOTHING.

Totally common.

Banish the scale... don't worry.  The surgery will work.
