bundles so that my fans and my followers can check it out so check them out after we get through all the science so the first thing that I want to talk about is something known as bacterial clearance okay bacterial clearance is our body’s ability to evacuate bacteria good or bad now what’s interesting is fasting has been shown to help expedite bacterial clearance of bad bacteria there was a study that was published in the scandinavian journal of immunology that took a look at subjects now full disclaimer and this study looked at mice but one thing that you need to know is that there’s a reason that researchers use mice it’s because they can go through things a little bit faster so here’s what’s interesting and I’ll get into the human studies a little bit later but this study found that when they put mice through alternate day fasting they were able to clear Salmonella out of their system over twice as fast so basically what was happening was when mice were infected with salmonella and they had them fast the Salmonella would just move through their system and not absorb now ultimately what they found was going on was that there was an increase in what’s called immunoglobulin a or IgA so what would happen is I GA heightens the immune response within the mucosal layer of the gut so with our gut we have our intestines and then on the out or kind of the the inside but the very outer edges of the gut we have a mucosal layer that mucosal layer is essentially our immune system within our gut so what happened is we have an elevated process of the immune response in that mucosal layer making it so the Salmonella didn’t get a chance to cross through it just got pushed out all through the body so it’s exactly what we want so elevated IgA is a very very good thing so I found that Salmonella instances weren’t nearly as bad in the mice that fasted now why is this actually happening and this translates directly in humans to it has to do with stress you see when we’re stressed out like when we’re fasting what ends up happening is our gut flora is affected by the IgA okay so what happens is when we fast we increase our levels of immunoglobulin a because we’re fasting and our gut is stressed out because doesn’t have food so we have a heightened immune response localized in our gut that we want and that changes the gut bacteria so it’s actually been found and it’s been found in humans too that if you’re deficient or low in IgA you’re having lower levels of beneficial gut bacteria so low levels of IgA equal more bad bacteria and less good bacteria pretty crazy that we actually want the immune response at this point in time now when we take it one step further we find that IgA where immunoglobulin a actually improves colonization within the gut so that means the good bacteria end up colonizing more now this has to do with something known as the commensal colonization factor so basically it means that when our body’s stressed out it does whatever it can to try to colonize good bacteria you see it’s like the body gets a signal that okay this person is under stress there’s a foreign invader or whatever it does whatever it can to instigate this commensal colonization factor to try to get more the good bacteria to grow it’s like our body already knows that good bacteria is going to fight an illness or a pathogen or whatever so it’s pretty powerful so basically allows good bacteria to grow so we have a double whammy effect bad bacteria gets out of the body a lot faster and good bacteria can colonize but let’s go ahead and take it even one step further because this is really interesting stuff bacteria in our guts send signals when they get hungry okay we don’t necessarily feel them so we’ve got thousands hundreds of thousands millions of trillions billions of bacteria in our gut like tons right we don’t feel when each individual bacteria gets hungry like okay we don’t necessarily feel it or mentally register it but the fact is they do get hungry and they send signals when they get hungry now there’s something known as the doubling rate the doubling rate is how often a specific bacteria gets hungry and how often it needs to eat and ultimately how often it doubles or grows right here’s the interesting thing most bad bacterias almost all of them have a very high rate of doubling okay they double at a fast rate which means they get hungry a lot which means that they’re needy kind of spoiled brats so what ends up happening when we’re fasting is they don’t get a chance to eat well if they’re hungry all the time they’re gonna be the ones that die first so sure they’re needy they want to eat all the time and then the moment that you starve them they just are like I can’t handle it I can’t handle this I’m so fragile and they just break down because they can’t get their food so what ends up happening is the good bacteria which don’t get as hungry as often they get a chance to grow and proliferate the bad bacteria die off the good bacteria grow so this is exactly what we want improves our ratio of good bacteria to bad well how does this actually play into your fat loss well let’s take a look at another study so a study published in the journal Cell Metabolism took a look at every other day fasting so one day not fasting one day fasting we wanted to find out the effect it actually had on the gut microbiota in general but they also wanted to find this fat link now what I mean by that is a link between our fat cells and the gut they found when people were fasting they had this what is called beijing of white fat so white fat doesn’t really do anything it sits on our bodies just adds insulation and some cushion but if it becomes Brown it actually develops the ability to increase our body heat which helps us burn fat so they found that fasting increased the beijing of white fat meaning white fat was turning to brown fat this is good for multiple reasons but in regards to the overall colonization of good bacteria and overall gut health in general we have to look at a whole nother angle you see it’s something called the microbiota fat axis so what we’re actually finding now is that Beijing of white fat increases a specific gene known as MC t1 not MCT oil but MC t1 okay this is a specific gene that actually encourages the up regulation of bacteria within our gun so we have multiple mechanisms in which this is working now when we have this Beijing and we have more of this MCT gene what’s happening is we have an increased fermentation of the good bacteria so that means we have lactate acetate in these other things coming in and fermenting good bacteria so we actually have another effect and it just has to do a simple cellular recycling it’s like our body’s getting more efficient a and PK is up regulating we’ve got different gene expression occurring that’s causing our body to get more efficient at utilizing its own fuel sources not just for our own energy but for our bacterial energy within our gut so based on this some of the things that you can do would be to actually after you break your fast like maybe an hour to after you have your break fast meal get those prebiotic fibers in because you’re in a great position to grow those good bacteria so you break your fast with whatever you break your fast with and then like an hour two hours later get a lot of asparagus get a lot of artichoke get a lot of celery in things that have prebiotic fiber to help grow the good bacteria that at that very point in time is the rising so there you have it quick summation of what happens with your gut with intermittent fasting as always keep it locked in and I’ll see you in the next video

Is Intermittent Fasting the Way to a Healthy Gut? – Thomas DeLauer
A study published in the Scandinavian Journal of Immunology found that intermittent fasting (alternate day fasting for 12 weeks) helped Salmonella-infected mice clear the pathogenic bacteria more quickly through a heightened immune response
Fasting prevented the bacteria from crossing out of the gut and resulted in elevated levels of IgA, an antibody or protein that boosts the integrity and immune function of mucous membranes like those lining the intestines
Specifically, compared with the infected ad libitum mice, the intermittently fasted infected animals had lower intestinal and systemic bacterial loads and higher IgA plasma cell levels
Why this Occurred
The underlying mechanisms of the protective effects of intermittent fasting against salmonella infection are likely related to the metabolic stress elicited by fasting
Stress is capable of modifying the normal intestinal flora composition, which in turn is able to modulate intestinal IgA production
IgA is the most abundant antibody in mucosal secretions and has been recognized as a first line of defense in protecting the intestinal epithelium from enteric pathogens
Fasting & Fat Burning – Microbiome
A study published in the journal Cell Metabolism found that every other day fasting alters the gut microbiome composition to promote an increase in the number of mitochondria in the fat tissue of mice
The study described a “microbiota-fat axis” linking fasting-induced microbial shifts to a beiging in white fat tissue
One underlying mechanism was likely because of increased expression of a gene (Mct1) coding for a receptor on white fat cells that drives acetate and lactate transport across their membranes
In other words, upregulation of Mct1 resulted in elevated gut microbe fermentation products acetate and lactate that in turn promoted white adipose tissue browning
