Did you ever answer the question of measurements? Did you take any measurements and did they change? Was there any body composition change (even though your body comp measurement is with a crappy scale)?
It would be interesting to see what would happen WITHOUT the additional protein, just the potatoes and nothing else. Would you lose lean body mass? Would your body hold on to it for a while? How long?
I think the interesting thing for me was to see how the whole water retention thing really messes with the clarity of the results. The low carb diet has a nice clean result because that confounding water retention issue is gone.
