I feel safe in saying that we agree on the point that folks should listen to their bodies. The problem, however, is that in my particular outlying case, listening to my body means undereating. One day I was on pace to have my normal four meals (My last was my third a little after midday) and ended the day feeling a bit crappy and miserable, and on the next I wound up covering over twice the distance despite only having ~700 calories at breakfast and aborting any later meals in the day after nausea kicked in when I had a ginger chew late in the morning. It's not a tactic that'd be sustainable over longer trips like the PCT, but it's what I have to do to make the most of my week out.
While it's possible that altitude and water intake contribute to my issues, I've had identical issues in the past when I was down around 4-5k elevation and ran out of medication (Was overdue by three days) and it's rare for me to drink less than a gallon/day. Every indicator I see points to the my colitis being the root cause, and the only tool I have for addressing issues relating to that is undereating.
