On yer bike!
The only stat I monitor is my waist using a tape measure once a week on Sunday. If my size is the same or larger than last week I make a concerted effort to eat less the coming week.
I have found that my commute is the perfect time to work out - since the start of the year I have been cycling 24 miles a day in London from zone 4 to Holborn and back - its awesome! The benefits are many and the main excuse is 'I cant be bothered' which frankly isn't good enough :)
