detubbification via perambulation
I must say this walking nearly 4 (steep) miles a day is paying off when it comes to reducing my mass. In just over a week of doing this every day, I've managed to lose roughly 3 lbs. I've not altered my diet much, which I still need to do (I eat plenty of good things but need to cut down on cake...), so this is primarily down to exercise.
I'm keeping an eye on things with the inestimable FatWatch - a modern day equivalent of the equally inestimable EatWatch:
The noticeable trend downwards in the last few days seems like good feedback to me that I'm doing the right thing!
You can also see the goal (slashed green line) plunging down somewhat faster at the bottom left of the graph...
