I just went through 6 cycles of 5-day IV chemotherapy (AIM) and I fasted for all of them, for a total of over 35 days of water-only fasting during the last 5 months. I can’t find the PubMed link right now but there were small studies that looked like healthy cells would go into kind of a suspend/preserve mode that lessened side effects, whereas cancer cells still experienced the intended cytotoxicity. I tolerated the treatments quite well, lost hair of course but only vomited twice during the whole time. Lost weight each time but was able to put it back on quickly during the following week for each cycle, though I do want to watch body composition (don’t want to trade muscle for fat).
Did it make a difference in effectiveness? I actually have my follow up scans tomorrow to find out. As you can imagine, I really really hope so.
