These changes were partially reverted upon refeeding Fig. However, frequency of pro-inflammatory MAITs producing TNFα and IFNγ significantly decreased upon fasting and were minimally affected by refeeding Fig.
Next, we tested all gut microbial taxa and gene functional KEGG 12GMM 13 modules for abundance shifts during fasting or refeeding, as well as persistent shifts across the 3-month study period, controlling for age, sex and any changes in medication Fig.
Fasting stimulated shifts in the abundance of several core commensals, which were reversed upon refeeding Fig. Many Clostridial Firmicutes shifted significantly in abundance, with an initial decrease in butyrate producers such as Faecalibacterium prausnitziiEubacterium rectale and Coprococcus comeswhich had also reverted after 3 months.
Interestingly, modeling the shift in C. comes abundance as a function of body-mass index BMI changes during the study yielded a better fit of the data than when it was modeled as a function of the fasting intervention.
Bacteroidaceae showed the opposite pattern. At the end of the refeeding period, a persistent depletion could be seen in Enterobacteriaceae, especially Escherichia coli. These shifts were accompanied by vast changes in microbial metabolic capacity Fig. Fasting enriched for propionate production capacity, mucin degradation gene modules, and diverse nutrient utilization pathways.
Reanalyzing previously published data, we compared the microbiome signatures of metformin use and MetS to those seen in our dataset 11 For ease of comparability, we proceeded with only human gut-specific functional modules GMM assessed from shotgun sequencing data available for the fasting arm.
Certain fasting- or refeeding-associated functional gene modules from our data were found to overlap with signatures of metformin usage or MetS, though there was little concordance on a taxonomic composition level, in line with previously described higher functional than taxonomic concordance between microbiomes.
Of note, when comparing the metformin signal to the MetS signal, it is clear that these two effects are functionally distinct and often oppose one another. In contrast, the inferred gut functional signature of metformin treatment shared some features with that of our fasting intervention Supplementary Fig.
Assessing the clinical relevance of our intervention, we inspected clinical outcomes in the two study arms. While DASH reduced office SBP after 3 months Fig. Because the BP response to fasting was heterogeneous in our cohort Fig. In the DASH-only arm, 17 patients were classified as responders with a median SBP decrease of 8.

Point color shows which time point comparison is plotted. Only the fasting arm had a significant effect on the microbiome, and while a smaller fraction of immune features were altered in the DASH-only arm, these were largely not significant in the fasting arm.
We compared the impact of fasting and refeeding in the complete fasting arm, in the BP responders of the fasting arm, and in the DASH-only arm Fig. Even at reduced statistical power, we were able to capture changes in the abundance of many gut microbial taxa that were uniquely characteristic of successful fasting treatment even 3 months post-fasting Fig.
Fasting combined with DASH resulted in the sustained depletion of Actinobacteria family members Corynebacteriaceae and Actinomycetaceae Fig. BP responders were uniquely characterized by immediate and sustained enrichment of an unclassified Clostridium species, with concomitant depletion of Sphingomonas genusS and Prevotellaceae NK3B31 group Fig.
In addition, responders experienced a significant and sustained enrichment of the butyrate-producer F. prausnitzii upon refeeding Fig. Virtually no overlap with effects seen in the equally powered DASH arm were found, indicating that fasting may be needed on top of a BP-reducing diet for these changes to occur Fig.

In profiling the microbial metabolic potential in BP responders, we focused on gene modules curated for relevance to metabolism in the human gut GMM On a functional level, responder-characteristic changes resemble those in the fasting arm at large, but with even more pronounced relative enrichment for propionate production MF, MF modules Fig.
Some modules were significantly altered in abundance only in this stratified subgroup, indicating these changes strongly characterize BP responders compared to non-responders Supplementary Data 7.
For example, pyruvate:formate lyase MF is depleted during recovery only in responders. Changes to the immunome of responders are similar to those seen in the unstratified fasting group and differ from those in the DASH arm Fig. In the fasting arm, several immune features related to pathogen-sensing and mucosal immunity e.
Upon fasting, the frequency of both pro- and anti-inflammatory adaptive immune cells showed a stronger decrease in responders, indicating a stronger anti-inflammatory effect of fasting in responders.

| We Care About Your Privacy | Those can be changes that will lead to increases in Ruminococcus and butyrate producers. So we are seeing that time-restricted eating will change transcription factors, it will change the overall composition and diversity of the gut microbiome, all of which are factors that help to decrease the overall inflammatory process. And then again, like I said, and we see that manifesting in a study on inflammatory bowel disease and we see that manifesting in a study looking overall at cytokine production. Kalea Wattles: Patrick, do you have a sense of the timeline here? How long until we might see a shift in their gut microbiome? So probably now almost 30 years. But you know, one other thing to note is that when you stop intermittent fasting, the changes go away. The diversity actually happens first and then the abundance happens over time. Kalea Wattles: I imagine with this shifting in the microbial composition that we also might notice some changes to metabolites like short-chain fatty acids. Patrick Hanaway: So again, the literature is very early at this point in time. What was your diet before you started? What gender are you, what type of eating pattern are you actually doing? Is it alternate-day feeding? Is it a time-restricted eating of 12, 14, 16 hours? Is it a process? Is it Buchinger or is it Ramadan? And one of the interesting things to me is they get different results, you know, based upon not only gender but also upon body types. So the effect on people who are overweight and obese is different than people who are not overweight in terms of the metabolite changes that we see going on. We do see some changes that relate to the short-chain fatty acids to butyrate itself. We see some other changes. What I think is going on, Kalea, is in relationship to the postbiotic effect. And we see some interesting data in C. But now when we talk about this, recall that, you know, we may say, oh short-chain fatty acids, of which there are three primary ones, you know, butyrate, acetate, and propionate. You know, there are short-chain fatty acids that come from insufficient digestion of proteins that can cause that are more fermentation byproducts, you know, but so even naming just those six various short-chain amino acids are six of more than a thousand different metabolites that are produced by the gut microbiome. Do you have any thoughts on that? Patrick Hanaway: Yeah, right. As significant of metabolic changes or even that kind of reset. And so that leads us into this conversation about gut endotoxins. Do we see an effect on endotoxins with fasting? And then we can talk about how that influences intestinal permeability. And that we do see that the production of LPS is decreased when there is time-restricted eating patterns and intermittent fasting that goes on. So we can describe that. And this leads me into an important point that I wanted to focus on, and that is that while, you know, we can look at research that says the new family called Christensenellaceae and the genus of Christensenella , and the species of Christensenella minuta , you know, have, have been associated with centenarians. We want to approach this through, you know, whole food dietary approaches with reasonable amounts of food at good timing, using time-restricted eating and intermittent fasting as a means of being able to reset the circadian rhythm of light and dark that our bodies have been using for the past, you know, , years. I mean, are you seeing this in the literature? Is there a gut-brain axis response to fasting? Patrick Hanaway: Absolutely. And so we see two different phenomena that are going on. And so the LPS-mediated neurodegeneration that you talked about may be manifesting itself primarily through alterations in the blood-brain barrier that lead to glial cell activation and inflammatory processes that are occurring in subsequent neurodegeneration. But we also find that there are, as I said, metabolic patterns that go on. And we see shifts that are going on in the overall distribution of the gut metabolites that are occurring that are having an effect on the anterior insular nucleus that then has an effect on the basal ganglia and the ability of movement or the effect on movement disorders. We see alterations in tryptophan pathways and kynurenic acid pathways that are stimulating inflammatory changes and degenerative changes in the brain. Do we see impacts to our immune health when we start a therapeutic fasting plan? And so we need to have a balance between all three of those that are going on. That, to me, forms the basis of health is working on the gut microbiome, supporting the immune system, using, you know, foods that are anti-inflammatory in nature. And that helps to balance the energy production pathways, you know, as well as the overall electron transport chain within the mitochondria to be able to optimize its efficiency for energy production that goes on. So I like to think of all three of those together. And some of that may be mediated through that apoptosis that we spoke about earlier. Kalea Wattles: There are so many clinical applications for fasting, and you mentioned earlier that you might be willing to share a little bit about this connection between fasting and the gut microbiome changes and benefits to cancer treatment. So I thought we could spend a few minutes and I would love to hear your thoughts on this topic. Patrick Hanaway: Well, as you know, this is a personal topic for me. I began really looking at intermittent fasting and fasting-mimicking diet and relating that to other cultures and working with insulin resistance about nine years ago. And in that timeframe, I found it to be really potent. And I was aware that much of the work that Dr. Valter Longo at USC had done was actually started with trying to do a fasting before chemo as a way of being able to optimize a differential stress response. You know, that is, how do we make the cancer cells more susceptible and the healthy cells less susceptible to chemotherapy? So that was the research that he had done, and, you know, then moved that into more anti-aging apoptosis, insulin resistance, you know, kind of promoting fasting-mimicking diets in a broader context. But the genesis of it was from his work on cancer and fasting before chemo. And he showed initial data in through his lab of the benefits of it, and they carried that forward. And so it was in the back of my head when I got cancer, you know, stage four cancer of the neck, in the aryepiglottic fold with lymph nodes on both sides. And I was doing a ketogenic diet at that point in time, which I later found helps to expand the therapeutic range of the radiation therapy. How long do you need to fast? You know, and they did fasting that looked at, you know, 24, 48, 72 hours. My weight stayed pretty stable. I think I lost five pounds through the eight weeks of treatment. But for those who are receiving chemotherapy, and again, to be clear, the data has been demonstrated of its efficacy, increased efficacy, and decreased toxicity in breast cancer. Not all of them are able to do it. And the data in the studies that have been done is calories per day, and I usually focus on a bone broth as a means of being able to do that, you know, in terms of that overall caloric intake during that period of time. But yeah, it is important and meaningful to me, and I think it made a big difference in my ability to move through, you know, chemotherapy is toxic by nature. How do we focus that toxicity differentially on the cancer cells and not on the beneficial cells of our body? Kalea Wattles: Well, Patrick, your experience and your story is so powerful and so compelling, and those of us who have heard you speak about your entire journey, I mean, it is really heartfelt, and I think we take away so many incredible insights from your experience. Do you think that the application of fasting and the ketogenic diet will become more standard in oncology moving forward? I mean, when are we going to see this take foot? So the first is around intermittent fasting or fasting before chemo. And I think that we have a lot of great opportunity to be able to do that. No one will ever do that. And so the number of dropouts in the studies that have been done are actually quite small, even though it was thought that no one would want to do it. The past decade has witnessed an explosion in fasting-relatedid research. According to Google Scholar, the last five years alone contain almost , articles that examine or mention fasting. Emeran Mayer, a professor of medicine and founding director of the Goodman Luskin Microbiome Center at the University of California, Los Angeles. When it comes to gut conditions such as inflammatory bowel disease IBD , he says the research is either absent or inconclusive. For a series of recent studies, a team of researchers based in the Netherlands and China examined the effects of Ramadan-style intermittent fasting on the gut microbiome—the billions of bacteria that reside in the human gastrointestinal tract. Ramadan comes up a lot in published research because it provides a real-world opportunity for experts to examine the effects of or hour fasts, which is what many popular intermittent fasting diets espouse. Maikel Peppelenbosch, a member of that research team and a professor of gastroenterology at Erasmus University Medical Center in the Netherlands. If you look at fasting in general, not only Ramadan, you see certain types of bacteria increasing. Unlike some other gut microorganisms, Lachnospiraceae can survive happily in an empty GI tract. Butyrate sends anti-inflammatory signals to the immune system, which could help reduce pain and other symptoms of gut dysfunction. Butyrate also improves the barrier function of the intestines, Peppelenbosch says. This is, potentially, a very big deal. If intermittent fasting can turn down inflammation and also help normalize the walls of the GI tract, those changes may have major therapeutic implications. Lachnospiraceae is only one of several types of helpful bacteria that research has linked to fasting plans. But at this point, there are still a lot of gaps in the science. The migrating motor complex refers to recurrent cycles of powerful contractions that sweep the contents of the gut, including its bacteria, down into the colon. Essentially, this motor complex behaves like a street-cleaning crew tidying up after a parade. It ensures the gut is cleared out and cleaned up in between meals, via minute repeating cycles that fasting allows to be become more frequent. Ideally, Mayer says people could for the most part adhere to the kind of time-restricted eating program that allows a full to hours each day for the motor complex to work. In other words, sticking to three meals a day and avoiding between-meal bites or nighttime snacks could be sufficient. Read More: The Truth About Fasting and Type 2 Diabetes. Some researchers have called it a helpful housekeeping mechanism, and it occurs naturally when the body goes without energy calories for an extended period of time. But these improvements have not yet been demonstrated in real-world clinical trials involving people. Eran Elinav, principal investigator of the Host-Microbiome Interaction Research Group at the Weizmann Institute of Science in Israel. This is likely to have health implications, though what those are, precisely, remains murky. |
