It's wonderful to hear of these techniques making their way into mainstream medical practice. I hope that is an indication of what we can look forward to in the near future.
I had similar results as your brother, losing an average of 2 pounds per day. So, on my 15 day fast, I lost a total of 30 pounds. On my 9 day fast, I lost 21 pounds, 9 of which were lost on the very first day.
