Does a high fat diet destroy your gut microbiome?

Video taken from the channel: Shawn Baker MD

A high-fat diet changes the bacterial communities in the gut and increases biomarkers of inflammation. The typical “Westernized” diet of processed and fast foods — high in fat. A high-fat diet appears to induce very specific changes in the ratios of the bacteria in the gut — high-fat diets are able to decrease the numbers of healthy gut bacteria while simultaneously increasing the numbers of less healthy gut bacteria. (16, 17, 22, 23, 26, 27, 28, 29). The study showed that a high-fat diet is linked to unfavorable changes in the type and numbers of gut bacteria, known as the microbiome, as well increasing inflammatory triggers in the body.

Stool samples collected by researchers showed the low-fat diet group had increased levels of butyrate (likely due to the increased levels of good gut bacteria) while the high-fat diet group had lower levels that at the start of the trial. It is known that diet interacts with gut microbes to calibrate the body’s immune defense capacity. The UAB-led researchers examined this further, with regard to aging and a high-fat diet. They.

The first issue is that most of the research related to a high-fat diet and the effects on the gut microbiome have been done in rodents. While rodent research is certainly valuable and there’s a lot that we can learn from it, the results don’t necessarily apply to humans, especially in the case of a high-fat diet. The Microbiome Diet limits sugary, fried, and processed foods, focusing instead on fresh produce, lean protein, healthy fats, and probioticand prebiotic-rich foods.

Purpose of review: This review will examine the recent scientific literature surrounding high-fat-diet (HFD)-induced alterations in gut microbiota and subsequent development of obesity and chronic disease risk. Recent findings: Excessive consumption of HFDs has undoubtedly contributed to the obesity epidemic. The mechanisms responsible for this relationship are, however, likely to be more. The types of fat that we consume in our diet tend to affect the makeup of our gut Microbiome.

There are two major types of dietary fats. Saturated (or bad fats) and unsaturated fats. Saturated fats that come from animal-based foods like beef, whole-fat milk, cheese, and butter have a negative impact on the gut microbiota and lead to obesity.

Your gut is home to trillions of microorganisms including bacteria, which make up a unique ecosystem called your gut microbiome. For your gut microbes to thrive, they need complex carbs for fuel. For that reason, they don’t flourish on high-fat, low-carb diets.

They equally won’t flourish on a low-fat, low-carb, high-protein diet!

Numerous studies conducted in rodents indicate that the incidence of chemically induced colon tumors is significantly lower in those animals fed fish oil–enriched diets than in those fed saturated fat– or vegetable oil–enriched diets.

Finally, the type of dietary lipids can differentially affect gut microbiota composition, and this contributes to phenotypic differences between mice fed with SFAs derived from lard and mice fed with omega-3 PUFA-rich fish oil (Caesar et al. 2015).

However, if you eat exclusively meat, you can disrupt your microbiome, particularly because the notable lack of fiber can cause a shortage of short-chain fatty acids (SCFAs), which your gut bacteria use as fuel to maintain the integrity of the intestinal wall.

  • Another misleading study.
    Title: Effects of Dietary Fat on Gut Microbiome…
    Conclusion: Higher fat consumption appears unfavorable to gut microbiome…
    Reality: Soybean Oil disrupts gut microbiome…not animal fat.

  • Cut a chicken’s head and it will still run on a certain distance so yeah movement on a dead animal is possible, but of course it’s impressive when you don’t know what is going on.

  • Humane, fast, efficient animal culling is the greatest good we can do. Unsupervised, uncontrolled animal deaths are terrible. If I was to go, I would want to go the same way as those cows. I rather kill a thousand animals personally for food than one animal unknowingly for no reason at all.

  • I think low carb diet you don’t need a lot of gut microbiome bugs. One would only need them is if they are on a heavy carb base diet.

  • Towards the end….you said that the Ketogenic diet is almost kind-of-like this way to reset your gut biome, starting off with a clean slate, and then re-introduce starches again.

    Is this now the NEW way to approach Keto? Are we witnessing here, in this video, keto being re-invented to a more optimal way so that we can have the best gut biome WHILE doing Keto as well? Ketosis? No Ketosis? I really need these answered so I can begin my journey the correct way and have proper long-term expectations, please.

  • What does he mean when he says we did not have carbs in antiquity? Makes no sense to m
    .e. Trees with fruit on them is not a new thing, nor have they throughout the world bred them for extra sugar. I like the idea of ketogenic diet but something is wrong when we over sell our position

  • Hi all. The app is now available on the play store. https://play.google.com/store/apps/details?id=com.andromo.dev516379.app830954

  • Though I don’t like industrial conveyor belt butchering, this is definitely a good example of humane slaughtering. Temple Grandin is genius.

  • What the vegetarians/vegans/high carb low fat people are forgetting, is that before all the air freight and the cargo ships started to move all kinds of vegetables and fruits all around the planet, people had to manage with the few seasonal things that they could grow. Fruits were only a short season on the northern half of the earth. So it was mainly meets and fish they could rely on! If all the freight plains/ships just stopped going, all the vegetarians and vegans would DIE!!! I will say that these people are also making pollution a problem for the planet due to the need f or long transport. Also insecticides are poisoning us and the soil!….just wanted to mention it….

  • To all those who say he said we weren’t eating carbs ever. You didn’t listen well. He said we were on mild keto diet through our history. We were “monkeys” for 2 million years and only last couple of 10000 years we found ways to produce high carb food and in only last 70 years we went into carb overdrive. Coincedentaly modern diseses start poping up. First in US and a bit later in Europe and other countries start catching up on carb party.

  • Taxes on junk food are usually in the form of a sales tax which disproportionately affects people who do not have high incomes poor people pay a higher tax overall because of sales tax furthermore frequently if ever there isn’t any healthy food available too many in poor neighborhoods additionally what is sold as juice is high fructose corn syrup colored water and that’s going to be taxed two people who do not have access to actual orange juice if you want to propose a tax BS committed and willing to go in to these neighborhoods and establish a healthy food bank as you are to securing your own high-income because to do otherwise is hypocritical and discriminatory

  • “I know there’s a lot more we can cover on this topic, but everyone on YouTube only has so much time…”….

    LET ME BE THE ONE TO JUDGE THAT! lol……give me MORE information. Lots more. If I want to spend two hours on one single video, I’m game especially if it comes from The Great and Powerful Oz himself Thomas DeLauer. This video felt way too short it caught my attention super-glued to the screen. But what it did in the end was make me confused and more scared to start Keto and I feel like it threw a monkey wrench into the equation, especially that I’m having difficulty organizing my ducks in a row regarding solid knowledge about the sciences of Keto and what’s optimal for my approach. Now I want to learn more.

    I walked away with the impression that Keto, in the long, long run, for longer term, isn’t the best choice but, rather, re-introduce the items that Dr. Stephen Cabral suggests we should re-introduce in order to achieve optimal gut performance. Am I right? Please bring that man back for a long series of teachings (and make the videos much longer). I’ll pay for those, even.

  • I’m doing animal only diet for January. I’ll eat fermented milk products and lots of cheese. This is apart from my usual diet which is this, plus anything the heck I want like 10% of the time. I can’t do plants as a main source of food

  • Those cows die a hell of a lot better than herbivores in the wild, to say nothing of the millions of animals killed by tractors, loss of habitat, and pesticides growing vegan approved foods.

  • This sounds interesting. If you have leaky gut, does the animal protein interfere with igniting antibodies? I want to try keto but don’t want to risk an adverse effect because of my leaky gut.

  • Is that Temple Grandin? She is amazingif I’m not mistaken, she came up with a whole system of slaughtering that was less traumatic to livestock. OkI just googled, it is her. Cool! On carnivore my stomach is settled, my cells feel like they are regenerating & I could write then thousand other awesome side effects. Woohoo World Carnivore Month!

  • Interesting. I take antibiotics when i get sick. I also take probiotics. Im fine dr perlmutter. Says antibiotics are bad but there.not. we need them. Everyone who gets sick needs them like me im not going to argue with. Dr perlmutter. He just says stuff but he. Doesn’t get sick like i do so anyway.

  • Remember that the animals we kill only have a live because we raise them. Vegans don’t raise animals. No animal is alive because of veganism.

  • I’ve been in ketosis for over 2 almost 3 months now and I’ve lost about 20 over 30 pounds, without starving myself and without feeling drained or weak. I feel strong. I think more clearly. Keto is the best thing that ever happened to me, and I’m never looking back!
