Is the KETOGENIC DIET good for the MICROBIOME?

hey Patrick here today I want to talk about the potential effects of a ketogenic diet on the gut microbiome the ketogenic diet is one of the fastest diet trends these days it is a high-fat diet where about 70 percent of the calories come from fat 25% from proteins and only 5% from carbohydrates through this way of eating the body goes into a state of ketosis and starts to use fair to boost ketone bodies which then provide an alternative energy fuel for the body the ketogenic diet was originally used as a treatment for epilepsy but by now there are thousands of research article showing the positive effects of the ketogenic diet on weight loss on mental performance and on a variety of modern diseases however the effects of a ketogenic diet on our gut microbiome are less well understood we know that the microbiome is extremely important for our overall health and well-being and in this video we will look at what’s a sign says on the impact of a ketogenic diet on our gut microbiome one reason high fat diets are formed upon is that an animal studies those diets I used to make the animal sick and studies on the microbe are are no different answers whenever you want to reduce a gut dysbiosis in an animal you put it on a high-fat diet however here so say while animal research is extremely valuable in some areas it doesn’t necessarily apply to human in nutritional research especially in the case of high-fat diets additionally in animal studies most commonly the high-fat diets use refined vegetable oils like canola oil or soya bean oil nothing you would find on an actual ketogenic diet but what is most striking is that an animal studies a high-fat diet usually still includes about 40 percent carbohydrates this is not even close to a low-carb diet where are the Cubs I usually restrict it to less than 20% of the calories and dr. Parramatta a neurologist with a focus on microbiome research describes this problem like this you know the benefits of introducing higher levels of fat into your diet are going to be erased and even made worse if you don’t at the same time cut sugars and carbs right the high-fiber carbs notwithstanding so let’s look at some studies on an actual ketogenic diet without high amounts of processed unhealthy fats or carbohydrates in a 2018 study all the net colleagues found that the beneficial effects of a ketogenic diet on epileptic seizures was actually mediated by the gut microbiome they found that specific microbes are increased on a ketogenic diet and that those species are necessary for an improvement of the neurotransmitter ratio of gaba to buta made which protects against epileptic seizures what is the most fascinating about society is that when the researchers took antibiotic treated mice and put them on a ketogenic diet they were not protected against epileptic seizures but the protection could be restored by a transplantation of these beneficial bacteria another 16 verse 16 week study looked at the effect of a ketogenic diet on the microbial composition and effects of the brain in mice and found that the ketogenic diet could increase the relative abundance of beneficial gut bacteria and reduce the bundles of poor inflammatory bacteria however there was also slight downside as the ketogenic diet decreased over diversity in the gut probably to a low intake of fiber even though the gut microbiome can adapt rapidly to new eating patterns it sometime takes a little bit until it is fully adjusted this was also seen in a study published in 2007 t researchers analyzed the microbiome of patients suffering from multiple sclerosis and found that the overall diversity was reduced and since the ketogenic diet shows promising results for Tweety motorist cruises they placed half of the patients on a ketogenic diet the researchers face at the effects of a ketogenic diet whereby Fezzik in the short term but your concentration on diversity we’re further reduced however they started to recover at week 12 and exceeded significantly at baseline values after 23 to 24 weeks on a ketogenic diet the researchers concluded their paper by saying that the ketogenic diet for six months completely restored the microbial biofilm ante and is an interesting interventional tool for prospective clinical studies another study on children with epilepsy found that those children have high amounts of pathogenic bacteria but that these harmful species could pretty much be replaced with beneficial bacteria after just a week on a ketogenic diet however research has also revealed some potential negative effects of the ketogenic diet on the gut microbiome a 2009 study by reinforce and colleagues found that people on a ketogenic diet had a significantly lower production of beneficial short-chain fatty acids which are produced when fibres fermented in the colon but I have to point out that the participants of the study were only consuming 30 grams of fiber per day and while it is true that it is easier to consume high amounts of fiber on a high carb diet it is still possible to get a decent amount of fiber on a ketogenic diet and form of green vegetables when it comes down to the micro bone we cannot yet be completely sure about the effects of a ketogenic diet however since a ketogenic diet excludes all processed foods refined carbohydrates and sugar this by itself can be beneficial for the gut I won’t tell about it but there’s some good research out there that shows that the gut health of many people improves if they nominate simple carbs and sugar in one of my previous videos I also talked about the diet of our hunter-gatherer ancestors the diet we have eaten for the majority of human history according to the research the diet composition fluctuates a lot throughout the year going down to the very low carbohydrate diets during winter periods at least for people living in higher latitudes which kind of suggests that we are used to very low carbohydrate diets at least for certain time periods so to sum up there’s not yet so much research out there and we can’t say for sure how a ketogenic diet impacts a micro biome long term however we have seen that the micro and sometimes just needs a little bit more time to adjust your new eating pattern and according to general microbiome research it might be a good idea to still get enough fiber in on a ketogenic diet in form of vegetables nuts and seeds when I had my first why was the ketogenic diet I went to the dog after a couple of weeks on the diet and get my blood shake and I was pretty happy with the results however whenever you start a more extreme diet you should get yourself shakes just to see if everything is okay and if the diet works for you one now if you want to try the ketogenic diet get your body slowly used to the high amounts of fat and don’t expect you got to handle it from one day to the other I’ve made the mistake before and my digestion was a little bit off for two days however what helped me on the way was the intake of probiotic food
