Today I weighed in at 14 stone, 4 pounds, which is the glorious milestone of 200 pounds.
I started about 18 months ago at around 250, so I've shed about a fifth. 50 pounds is what one of my electric bicycles weighs, so I'd been dragging that around with me everywhere.
I wish I could say that I feel bouncy and light, but the back problem hasn't gone away yet, although it is improving slowly. But before the back problem developed, I was fine at running up stairs two at a time - now I can barely stagger one by one.
But the back is improving, and I'm optimistic about the future, both in terms of back pain and weight loss.
