I find myself contributing my standard line on this - so forgive me if you have read me over the years saying the same darned thing

.
I have experimented with all sorts of fasts, and long fasts. My longest, on bone broth, and cream in coffee as well as herb teas and black tea, was 10-11 days.
If we as a species found fasting easier as the days without food stretched out - we would be a very strange species indeed! The idea is - I believe, if we were running wild with scarce or no food - to get food pronto quick smart! And make no bones about it. Is the driving force. Prompted by - the rather hard to ignore signals of hunger. As in being rather, er, uncomfortable! Otherwise we as a species would not still be doing so well and in such plentiful numbers!
But, both my parents' cultural influences were not predominantly English. My understanding of English culture, and correct me if I am wrong - is it is considered decent and polite to understate states of discomfort, pain, and suffering. I believe I see evidence of this all over this particular 'global community', when coming from an English cultural perspective? Again - correct me if I am wrong.
My own take is, fasting is extremely 'uncomfortable'. (As are Very Low Calorie Diets, of which I have done twice.) The longer the fast (or VLCD) - the worse it is. Forgive me if I sound like a Vulcan, but is this not logical? (I've been sick at home for a few days, and holed up watching old episodes of Star Trek.) It does not, from my own pov, get easier the longer one is hungry, and lives with hunger. We have marvellous ways to adapt - my own being watching a lot of docos on all aspects of food, and sorting out my recipe collections - but adaptation to a very difficult state it is.
