What does the caveat mean? Should I avoid doing HITT first thing in the morning, after not having eaten? (note that I'm polyphasic at present, so unless I get some sort of fasting habit going, I may have eaten as recently as 4h prior)
The caveat mainly targets those on some low-carb dietary regimen. If you were to break a fast (can't give a specific fast length, sorry) with exercise then maybe have a banana 15-30 minutes or so before starting, depending upon your metabolic speed.
Does this apply to you? If a highly confident no, then have at it at your own liability!
Do you have a citation for 15-30 minutes being a reasonable time for blood glucose levels changing in response to consuming a banana? I remember reading that it takes significantly longer than that, up to 150 minutes, but I can't find a proper source at the moment. The closest I can find is the 4-hour body, and I don't know how trustworthy it is. It also says that fructose may lower blood glucose levels.
I don't, actually. I ran a year long informal experiment on myself, trying to measure my metabolic rate / caloric need per hour, and have a recollection of reading that ingesting a banana before a workout should provide enough glucose for an hour (I don't think it specified for what activity; I found that the banana lasted for the first forty-five minutes of a treadmill 10k run at a pace fluctuating between ~4:30 and ~6:00 minutes per kilometre*) - both probably inform that 15-30 minute figure. Your metabolic speed will vary, and not necessarily within that range.
*By "last", I mean a subjective sense of being energized and having enough fuel. I realise now that may not be a reliable indicator.
