My last six-and-a-half months:
That plan line is 0.38 lbs/day.
Since this is my first post and all, I started 15 Jan 2008 at 304 lbs. This current curve is the 'second push to the finish' after slacking off last summer; I started again August 4th, at 240.6.
Currently at 196.6. Plan to be 172, 13% bf; BMI 24.2, we'll see where I bottom out, and where I stay is where it'll be easy to maintain.
There was nothing easy about this progress. Stay in there, folks, and yes, I weigh myself four times a day (and track all four lines).
