Dr. Paul Mason – 'From fibre to the microbiome: low carb gut health'



  1. I can confirm by personal experience that removing fibers is great for bloating and constipation. We are not cows or goats, we don't need plant food

  2. And I have a doubt after keto I've my hit my weight target .
    Now I just need a diet which wouldn't cause weight gain
    A normal diet is also fine as long as it doesn't increase my weight. Please suggest a balanced diet (normal) for me
    I am okay with doing this diet forever but everyone's saying it's not safe long-term
    Please please someone respond
    Please Don't skip this message!!

  3. I found this in a 2017 publication and will just include the conclusion:


    There remains much misinformation in the literature about

    the physical effects of fiber in the gut. In the small bowel,

    fiber-related health benefits are dependent on the viscosity of

    soluble fibers. High viscosity fibers (eg, gel-forming b-glucan,

    psyllium, and raw guar gum) can have a significant beneficial

    effect on both cholesterol and glycemic control. In contrast,

    low viscosity/nonviscous fibers (eg, low-molecular-weight

    b-glucan, methylcellulose, inulin, wheat dextrin) and insoluble

    fiber (eg, wheat bran and cellulose) have no significant

    effect on cholesterol concentrations or glycemic control, and

    can be used as a placebo. In the large bowel, there are two

    mechanisms that drive a regularity/laxative benefit: insoluble

    fiber mechanically irritates the gut mucosa to stimulate mucous/

    water secretion, and soluble gel-forming fiber that retains

    a high-water holding capacity that resists dehydration.

    To exert a regularity benefit or laxative effect, a fiber must

    resist fermentation to remain intact and present throughout

    the large bowel (be present in stool), and significantly increase

    stool water content. The increase in stool water content

    provides bulky/soft/easy-to-pass stools. The plastic effect

    of insoluble fiber (eg, wheat bran) is dependent on particle

    size/coarseness: large/coarse particles have a significant

    laxative effect; small/smooth particles can have a constipating

    effect (add only to the dry mass of stool, decreasing

    percent water content/hardening stools). The high waterholding

    capacity of a nonfermented gel-forming fiber (eg,

    psyllium) can provide a dichotomous stool normalizing effect;

    that is, soften hard stool in constipation and firm-up loose/

    liquid stools in diarrhea, and normalizing stool form in patients

    with irritable bowel syndrome. In contrast, the lack of

    water-holding capacity for fine insoluble fiber (eg, fine wheat

    bran) and fermentable soluble fiber (eg, wheat dextrin) can

    lead to a constipating effect, resulting in a decrease in stool

    water content/harder stools. It is therefore essential to

    recognize which fibers possess specific health-promoting

    properties, and which fiber supplements have consistent,

    rigorous evidence of clinically meaningful health benefits at

    the doses commonly available in the market place (Table 3)."

  4. does anyone here know if dr mason published any papers covering this topic? i want to see the study he made in detail, but cannot find anything besides the slides that were shown.

  5. يا ريت فيه ترجمة بالعربي انا جاية من حلقة الدكتور علي

  7. 13:25 – On lactose and bloating – If milk is consumed whole and unprocessed, it contains lactase, an enzyme that digests the lactose. Unprocessed milk also contains naturally occurring beneficial bacteria, aka probiotics, that consume the lactose and convert it to lactic acid. These are two reasons that many who are lactose intolerant find that they can enjoy real, whole, unprocessed milk with no trouble at all.

    Milk from cows on high fiber diets – which they are designed to eat – including pasture, hay, etc, is higher in butterfat than the 'whole' milk in grocery stores, which has had the cream removed and then added back to 3.25% butterfat. Milk from Jersey cows and many other breeds can be as high as 5% butterfat, and sometimes even higher. The lactose content in this milk is proportionately lower.

    For more info on the numerous differences between the real thing and the highly processed stuff sold in supermarkets, visit RealMilk.com

    I do not produce milk, market it, and have no ties to the dairy industry.

  8. 13:08 Rabbits – What Dr. Mason does not show is that rabbits also aid their digestion, like most all true herbivore mammals, by eating their food more than once. This is because, even with the help of microbes, plants are difficult to digest. In fact, no animal can do it; it actually the mircobes they host that digest the plant material they eat.

    Ruminants, including cattle, sheep, deer, wildebeast, antelope, yaks, etc bring up the food they have already eaten back into their mouths, re-chew and re-swallow it. They spend most of their day either eating or re-eating their food. Hindgut fermenters, like rabbits and gorillas, eat the food that has already gone all the way through their digestive tracts. Yup, that is exactly what it sounds like.

  9. If the constipation is caused by motility issues, then that is what needs to be addressed. Diet is secondary. If you have good motility, then fiber (consumed with lots of water) shouldn't be an issue. Treating the symptoms is not really a solution.

  10. on 10:10 you claim that the ketones in the blood can have the same nourishing effect on gut cells as ketones from butyrates from fiber in the colon itself. Any articles to back this up? my GI and dietician want to put me on a plant based diet but i want to show them evidence that my tactic (although it might need some polishing) could work

  11. So there is a radomized trial showing the oposite effects of what this Dr is caliming: A randomized trial of the effects of flaxseed to manage constipation

    Also there is a meta study from 2012 who looks as studies with the same level of soundness (1300 of them) and concludes adding fiber is effective in most cases for treating constipation.

    Now this took 5 min or googeling…. this dude obv is trying to pull the covers over peoples eyes…

    Not saying either or, because we are all different, but know that everyone is trying to sell you something or acting on confirmation bias.

  13. Arguably the most revolutionary, earth-shattering talk available on YouTube right now. Frankly I'm surprised it hasn't been banned!

  14. 12:46: " 'low biologically available glucose diet' – because we can’t say low-carb diet in a diabetes journal?" LOL We're starting to see more and more backsliding language, as prestigious journals, organizations, and universities figure out an elegant way to reverse position without upsetting Agriculture. Look to see the phrase "Medical Nutrition Therapy" thrown about related to low-carb diets. For example the American Diabetes Association’s new Consensus Report of April 18, 2019: "This moves a low carbohydrate eating pattern and a very low carbohydrate (ketogenic) eating pattern from the realm of a popular lifestyle choice to Medical Nutrition Therapy for the purpose of disease management." 🙂 I suppose those of us not yet diagnosed are supposed to keep stuffing ourselves with so-called "heart-healthy grains" until a doctor says stop.
