While it does appear to work for many, I personally lost about 20% weight or 40lbs, with seemingly zero effect on blood pressure. I do measure it around the same time of the day, same place, nearly same condition... So it is not about inconsistencies of measurement - I had elevated blood pressure for as long as I remember. My BP does respond to exercise (or more likely to body heating up) for short period of time, and to meds, but meds make it very inconvenient since I have to plan it around my day - having meds and working on something outside in Texas heat = too low BP.
