Here's the graph:
Overall, I lost ~11 pounds in 2009. Optimistically, that's around a pound a month, which is nothing spectacular but not bad considering I wasn't on any diet in particular. Also, the overall trend was downward and I never got even close to my original weight.
Pessimistically, one pound a month is pretty darn low, and I seemed to stall out around September/October, and I'm not at my goal weight of 180, which is really above where I should be, according to BMI. And yeah, I know BMI is kinda arbitrary, but I'm not sure how else to find a healthy target weight.
Hopefully resetting the graph will help me focus on getting down to 180 and beyond!
