🤮
Thanks, Siim. Great interview.
Will definitely skip this one.
Because he’s sponsored by big broccoli?
@@An-it5sw gotta love how ppl cry about meat industry etc as if agriculture isn’t the biggest moneyprinter worldwide lel
Could you interview someone whos animal based, so we could see hear someone with a opposite view. Great content as always.
Now do an interview with his rival which is Paul Saladino. Can’t believe he still recommends people cooking with canola oil😅
I’m generally turned off by the carnivore movement (and keto), but watching Paul Saladino what I eat in a day, it seems he has really evolved himself from a few years ago and stopped the anti-carb at least.
Why do think seed oils are bad? I feel as though it doesn’t matter if there are all these mechanisms and all that matters are outcomes, and the outcomes don’t show any health problems and often the opposite. We have our own bias and hopes that somehow “natural” is good and “unnatural” is bad, but we have to detach from that and accept maybe we’re wrong and that’s okay. It’s the same with everything, from microplastics to soy. Theoretically, it’s killing us. Theoretically even exercise is killing us. It causes oxidative stress, Inflammation, bone mineral loss, etc, yet when we follow people who do more exercise, they die less.
Would be more entertaining with Bart Kay.

DNA, ancestral diet… I discovered my DNA requires a LOT of choline, lower carb, lower saturated fats…
Everyone ate high amounts of sat fats from the beginning. Reason for making brain development possible even.
Why do you think an ancestral diet is better than just eating how the mortality data and randomized control trials demonstrate is healthier? I feel that studies on average funding people die less from eating fruits is better than saying that you should eat fruits,…because people before ate it? I feel as though we can’t say something is good simply because people before did it. Eating chard meat was great before to quickly sanitize the meat and get quick nutrition, because the chances of developing cancer five decades from then doesn’t matter. The chances of living that long were already low, but today it’s different. The demands of the past aren’t the same as today.
@@martinsvensson6884 everyone? The reason? I don’t think you have data for that 😉. My ancestors survived on cod.
@@seban-jackedweeb5513 mortality data is on populations, not individuals, averages do not account for individual differences. For example, I discovered that I have a high need for choline, a zinc transporter problem, an enzyme deficiency for metabolizing folate…
@@seban-jackedweeb5513 Because that is how evolution functions. The further away you are from what you are adapted to, the more problems you are going to get.
Try feeding animals things they didnt eat during evolution and see what happens.
Oh Siim. I haven’t listened. And I won’t. Why? I’ve given Gil many listens. He is one of THE worse examples of scientism versus science.
He is the literal poster boy of Richard Feynman how not to be a scientist.
Thomas jumped the shark. I truly respect you.
Let me know if you politely disagreed with him. And pointed out the failings of nutritional epidemiology and mentioned anthropology etc.
Hope you are not another jump the shark. Oh boy. I’m all for scientific debate. Can’t do it with Gil. He mistakes his scientism for science.
Playing with fire young Siim. Having Gil on.
I agree that having Gil on is quite a stretch. Tbh Siim’s content used to be excellent but now it has really started to drop off.
@@lew3733 it’s sad then. I hoped it wasn’t a jump the shark moment. Someone Sarah B ‘paleo mom’ has gone full nutritional epidemiology sith. I don’t even bother with Thomas D anymore, not worth my time….
Siim….it’s not just me. Flirting with jumping the ship with Gil. He’s… keeping people confused. It is up to them to decide if ideas of worth or not.
But wow. I’m just saddened TBH.
Just cut out “”Manufactured”” Foods, and eat Natural.
gil a good one
Thank you for talking with actual scientists
lol, you mean a shill
@@erikahuxley elaborate please
“Vegetable oils .. the outcome is better..” was that a mistake? Misspoke ? Otherwise, overall,l fantastic debate.
Wait why “Canola” oil is healthy ? Are you sure ?
Ok, let’s follow the Carvalho’s scientific method explained in the video to try to discover cause and effect of sunburns in the summer:
1 – We select two cohorts in the same population. Cohort A has more sunburns than B. Let’s see the amount of ice-cream they eat.
2 – 90% of cohort A have eaten ice-cream. 45% of cohort B have eaten ice-cream.
3 – Let’s now do some adjustment models: Smoking, exercise and BMI.
Conclusion: Ice-cream is the CAUSE of sunburns in summer. Exercise and higher BMI is also associated with more sunburns. To reduce your RISK of sunburning: stop eating ice-cream, don’t exercise in summer and reduce your BMI.
…And this is exactly the method used by this guy to say that LDL is the cause of heart disease or that meat causes cancer. “Anecdotal” of people in keto and carnivore breaks that hypothesis, having zero plaque or cancer… but let’s say that it’s just “anecdotal”…science is broken because guys like Carvalho…
concerning LDL-C, for example, there are other types of studies and some interesting findings – Fernández-Friera et al (2017). Normal LDL-Cholesterol Levels Are Associated With Subclinical Atherosclerosis in the Absence of Risk Factors. Journal of the American College of Cardiology, 70(24), 2979–2991.
Very fact based guest 👍.
16:10 there is some more nuance on studies on *specific populations* though – the diet of Okinawans was fairly well documented (together with some of the positive outcomes), and then researchers followed a sample of Okinawans who migrated and therefore changed their diet (toward more Western-style, with the predictable decrease in positive outcomes) – so research design-wise there are some options that may produce sufficiently valid conclusions by using *quasi-experiments* rather than “real” experiments
I’ve kind of narrowed it down…. avoid processed foods. Avoid excessive amounts of high glycemic carbohydrates and excess fructose and alcohol. Avoid excessive saturated fat. Consume lean and high quality meats, lean dairy sources, with a diet rich in vegetables, nuts, legumes, shrooms (legal or otherwise) and omega 3 fatty acids. Some people might have allergies to certain foods (mostly plant foods) and need to avoid them, but the average person pushing for longevity should get their plants. Throw in zone 2/5 cardio and weight training (pull ups, bench press), proper amounts of sleep, good habits, friendship and laughter. A modest caloric deficit and low BMI are best.
Beware the carnivore and vegan fundamentalists with their black and white ideologies. Take supplemental Magnesium, and get enough glycine (or collagen) in your diet. Wear sunblock on your face and neck in the summer, if you want to age more gracefully with less wrinkles. Get enough dietary choline, so eat eggs and their yolks. Cut back sodium by using potassium chloride salt or 50/50 salt.
Real food, Whole food, and especially avoid the processed seed oils.
