The end of my 'anything goes' experiment?

158 pounds, 31" waist.  Lost only .25 inches this week which leads me to three possible reasons.

1.  My 'anything goes' experiment over the last couple of weeks isn't working anymore.  I've been drinking nothing but water, eating a protein-rich breakfast and taking PAGG religiously.. but nothing else.  If I get a healthy meal.. good.  If not, whatever.  I've eaten out, enjoyed ice cream, etc for the last two+ weeks and still lost major inches.  Maybe as I get leaner, it gets more difficult to shed inches?  It only makes sense.

2.  I didn't drink as much water as I should've.  Easily fixed.

3.  Maybe 31" is my natural stasis.  Its what I measured over a year ago when I ran 30+ miles a week.. at the peak of my physical health.  Does it get any better than 31 inches?

I think I can do better than 31.  I see all sorts of definition in the shoulder/back area.  Chest is finally coming back around, but there is still a bit of fluff on the stomach.

This coming week is gonna be rough.  I'll be away again on business.. and its totally impossible to diet when doing so.  I'll stay with the water/PAGG and try to offset poor diet by hitting the hotel gym a few times.  I'm really anxious to see what this next week holds!
