Did I actually Gain Weight?

Earlier in the month, I was concerned that I might lose weight on this extreme budget diet. However, when I weighed myself I was 3 pounds heavier then the scales at the doctors office read a couple years back.
Of course that could mean that in the last couple of years that I had gained weight, or that the 2 scales are giving slightly different results.
No mater it is obvious that I did not go below the 142 pounds, from my last doctors visit. For that I am happy, but I still have 59 days to go in this experiment. I could still shed a few pounds, even though that was not was intended by this experiment.
