It's mostly hormones that control hunger and in the gut it's ghrelin which basically sends signals to the hypothalamus and as the stomach empties ghrelin increases and when the stomach fills up ghrelin decreases and works in conjunction with a couple of peptides. Leptin is the other hormone that effects our eating and leptin regulates glucose and lipid metabolism in peripheral tissues and inflammation and excess weight does create something called leptin resistance. It's a big deal in obesity research.It is!
There's a lot of research that says the bacteria in our gut send signals to the brain that cause us to crave one food type over another. So if your gut microbiome is attuned to eating simple carbs, you get a feedback loop for junk foods. Maybe it's deflecting responsibility away from the individual, but anecdotally I've had experiences like this. Keeping a healthy microbiome is one of the reasons I like making my own yogurt and kimchi and eat natto and fresh miso regularly.
Back to the microbiome. Yeah fermented food increases the diversity of our gut microbiome and could help with lowering inflammation as well. Our microbiome is different than anyone else microbiome based on what bacteria we've been exposed to from the minute we are born, who else came into contact during birth, whether we were breast fed or not, if we had pets as infants, what types of foods we ate and so on and it's those first few years that defines our basic health of our microbiome. Where we live either in a rural or urban environment, do we live in Iceland, Australia, NY City or we're small tribes living in Sub Saharan Africa all effect our microbiome and it's difficult to say what a healthy microbiome actually is. We have what 100 trillion microbiota associated with our body with most in our colon with hundreds, even up to a thousand different species. Our immune system mostly resides in our gut, i find that fascinating. Research where they do longitudinal studies monitoring human dietary interventions and see what happens with biomarkers and improved health outcomes as it pertains to gut biome and what might be considered a healthy microbiome and even then healthy for who is still a really important question. interesting stuff.
EDIT TO ADD: What's crazy is that we have many microbiomes in and on our body. In our mouth, on our skin, in our ears and of course all the way down and through our digestive tract to our colon. Also different species of microbiota reside in different places throughout our digestive track starting in our mouth, that don't travel, that only thrive in that one place and is controlled by our PH in our digestive tract.
