This explains why stressed people are overeating - they misinterpret their anxiety as feeling hungry and develop a habit of "eating it over".
Bacteria stuff is just BS.
I had my entire large intestine removed over several operations, and i felt no difference in my mood
Wow, usually the first step is to prescribe antidepressants
There is a simpler question - could one tell anxiety from hunger? (I can't) or the feeling of being hungry "reuses anxiety" in context? This explains why stressed people are overeating - they misinterpret their anxiety as feeling hungry and develop a habit of "eating it over". Bacteria stuff is just BS.
Why? References?

Actually it doesn't. Why are they feeling anxious? How do they misinterpret anxiety for the feeling of hunger? Why is the feeling of anxiety and hunger the same (as you assert, I strongly disagree). It is not even close to as simple as you suggest. Maybe bacteria has a role and maybe not. What is known is that the microbiome does have a larger role to play then we currently understand/realize. To what extent and exactly how is still an open question.

No, it was removed for ulcerative colitis. If gut bacteria affected mood I would have noticed now I have a lot less but there wasn't any change.

Except that for a cause-effect relationship, you need a kind of "all else being equal" scenario. But since we take antibiotics when we are ill, we already are in an unusual state of the body. So any mood swings, if noticed at all, are just as likely (and given that we tend look among the familiar things first, I'd say more likely) to be attributed to things like poor sleep or other side-effects of whatever disease ca…
There should be a lasting effect when you replace your gut bacteria, not just some mood swings.
There really isn't much if any evidence supporting this hypothesis at the moment, and even if there is an effect it appears to be relatively minor.
I'm curious why these articles are posted so often on HN. Do a lot of people here have mood disorders? If so, would it not be better to look at the more obvious causes -- lifestyle and stress -- rather than trying to pin the blame on some outside entity? There really isn't much if any evidence supporting this hypothesis at the moment, and even if there is an effect it appears to be relatively minor.
Another thing I've been pondering occasionally is what this and other discoveries might mean if cryonic neuropreservation (head/brain only) storage & reversal is ever practical, or if full head transplants become a viable surgery. Just how much of actual personness is stored in places other than just the brain? Surely the hormonal (endocrine?) systems of the body, as well as things like the microbiome are going to pl…
