[@lastcall42]

Ok, but check this out. 100% on the real, I lost 110 lbs (265 to 155) eating McDonald's 3 to 4 times a day. Here's how. The mobile APP has d3als; buy 1 get 1 for .29 cents breakfast sandwiches, also buy 1 get 1 .29 cents dbl cheeseburgers. I consume only 3 beverages on the regular. Water, black coffee, or Michelob Ultra. I'd eat 1 brkfst sandwich right away, the other 3 hrs later. Get the dbl chsbrgrs at lunch and eat 1 then, one for dinner. Keep in mind, it's mostly water I drink during the day. So basically, I was chasing calories, and ceilinged out at 1700. Itresulted in another 110 lb loss.

[@christianvollenhoven]

@@SirPhytone is it more ethical though? The carbon cost of flying and shipping in all of the foods required to make that possible is huge.

[@SirPhytone]

​@@christianvollenhoven Yes, I literally cannot see a case where it would not be more ethical. 1. 95% of animal products are factory farmed, so the meat industry is extremely unethical. And even if you farm your own animals, killing them for meat cannot be done in an ethical/humane way, unfortunately it is impossible. 2. Said animals also need to be fed plants, often that is imported soy. In fact the two biggest reasons for rainforest deforestation is soy for animal feed and cattle farming! 3. Look up the land use per kCalories of food, takes 100x the land to have beef over potatoes for example, or ~60x for nuts. It's all very well to say it's not so bad to farm meat on a local farm and use the manure to fertilise crops etc, but the reality is with the current world population, it is only the very privileged who can do that. Not only are costs much much higher when meat is farmed in this way,, but there simply isn't enough space on the planet.

This is one of the first videos of yours I've watched and I have to say it was fascinating. I've been vegetarian for about 7 years and while I'm not sure I can see that changing any time soon, this has given me a lot to think about in terms of other effects that we don't tend to think about.

[@justroberto5052]

are you serious? and what good points did you feel were made?

[@mbaxter22]

If you’re vegetarian this tells me you already possess strong food discipline. I think vegans and vegetarians make good carnivores because they’ve already learned to master their food intake. Going from SAD to carnivore is probably even more difficult. Try it. Go carnivore for a month. You will thrive beyond all expectations.

[@xandermarjoram8622]

@@justroberto5052 Just came back to watch this video again (I was notified by another reply!) The main points were about how just because you're eating plants doesn't mean animals haven't died to grow them (is killing twenty mice and tens of thousands of insects better than killing a single cow or pig, if done humanely?), and you can't guarantee that the land is being managed sustainably. I'm still vegetarian for what it's worth.

[@thenayancat8802]

I don't think these are actually good points. Firstly, even grass-fed animals are typically fed crops (hay and silage, if not food crops outright as many are) - so many of the same issues with crop harvesting, tilling, etc, apply to animals. Secondly, if you're going with anything other than pastured ruminants (cows + sheep), there's a huge amount of crops being grown to feed the animals. ie the overwhelming majority of pigs+chickens in the UK are factory farmed and fed soya etc. I can absolutely 100% guarantee you that none of these lives can be termed "humane" treatment. Thirdly, the evidence on animal deaths in crop production is extremely mixed. Intuitively it may make sense that you're killing all the mice, but is it not rather more realistic that the mice might notice the massive farm machinery coming towards them, and temporarily move out of the way? Indeed this is what some evidence shows (I can dig up a paper if you like). Fourthly, Dave generally likes to attribute as many negatives as possible to plant farming and as little as possible to animals. How many insects do cows kill? Finally, it's worth considering how scalable the type of agriculture Dave's favouring here is (pastured ruminants, mainly cows). How many people do you think the UK can feed with pastured cows alone? Bear in mind we are already massively net importers of food, and typically pastured cows are among the most inefficient users of agricultural land, be it arable or not. @@xandermarjoram8622

I tend to binge on documentaries and this was far better than anything I've watched recently on Netflix and the like. Incredible production for just yourself, and avoiding being sensationalist or dogmatic. Where there is speculation you come back quickly and identify that. Calm, methodical, curious but cautious, and clearly structured. I think there's a real public health point to it as well. Being surrounded by fast food when you have limited time, e.g. office work or travel, makes it very hard for people who are susceptible to bad eating habits to actively manage their diet and break free from it. Just knowing that something like this is an option could help people with that, and then wean them off the allure of fast food altogether. Anyway, I'm waffling... really enjoyed it :)

@@LeoShoSilva you won't be able to get enough calories to do that on meat only.

That's why anyone can get good results only eating meat but to be a successful vegan you literally need a masters degree in nutrition or you will end up depleted in certain amino acids and/or just eating sugary junk.

Hi Dave, thanks for this. It’s been absolutely invaluable for shifting my mindset even in the short time it’s been up. I’ve returned to climbing 25 years after I got my climbers badge in Scouts. But the frustration I’m suffering currently is that my weight and eating habits are wildly different to the young Dan and it’s stifling my progress. Although I feel that I have some balance in my diet - it’s majority vegetarian, majority freshly home cooked by me - but I have, despite this, an extraordinary and seemingly unbreakable attachment to junk food (the psychiatric trigger of which, is almost certainly complex and better left undisturbed - nothing weird, just had a slightly unusual upbringing) I have McDonalds/KFC/etc probably twice/thrice a week and I’ve been wondering why despite climbing with similar regularity I’m not dropping weight and am having outrageous dips in energy, concentration and mood throughout the days. And this has been happening in essence, for decades. So much of what you discussed resonated with me and my own battles that it feels like a weight off the shoulders, if that makes sense. I did some research after you posted and I watched, and I realised, as well as the fast food hypnosis, how insane my carbohydrate intake is, because I’m making compensation in my diet for the lack of meat (my partner is the vegetarian) with things like pasta/rice/bread. So I’ve drawn up what feels like a promising and achievable keto plan and am going to try it for as long as you did the burgers for and see where I’m at. Thanks again for the video Dave, I don’t think you could have timed it any better.

[@benja_mint]

Good and interesting video. I haven't finished watching yet, but I notice a fallacy in the farming section. It's mentioned that crop-farming results in many animal deaths, and no food source is death free. True, But keep in mind that in many (most?) Western countries the animals we eat aren't grassfed but rather eat corn and soy etc.. So by eating an animal that ate plant crops you didn't avoid all the problems of crop farming. You just did multi-tasking and contributed to both.

[@MangoJunkie]

I really enjoy this video and the depth of research you go to to explore these complex topics. I just felt as though the section about replacing meat products was not as thorough. It was explained how the research is potentially flawed on meat consumption and that we destroy ecosystems for harvesting but it was stated as if to say that plant consumption is just as bad even though the evidence (as imperfect as it may be) still suggests otherwise and your argument just picked some flaws in the research. I'm not sure an argument can be made for meat consumption as being more ethical just yet. I just worry that the framing of this argument causes non-ethical meat eaters to have their bias confirmed which will probably do more damage than having those people eat plant based at least while ethical and sustainable solutions are being conceived and implemented.

[@jonnyscheibenhauer4059]

I had the same thoughts. I fully agree that a carnivorous or keto diet can be healthy but the environmental and ethical implications of meat consumption were downplayed by unfitting comparisons. Saying that plant farming kills animals and comparing that to animal consumption is already kinda shady, but comparing the effects of the "best way of beef production" to worst case industrial agriculture is just a disingenuous argument in my book

[@DDracee]

ethically the ideal would be a balanced diet, balance of meat and harvesting, on the sole premise of maintaining the carbon cycle, too much of either disrupts the carbon cycle and leads to infertile lands, which then leads to mass death of the local ecosystems and forces industries to move on to new land to destroy (which is actually a growing problem in USA) as for health, i don't think it really matters as long as you work from clean/raw ingredients, there's blue zones out there of pretty much all diets imaginable, just avoid sugars, processed foods and seed oils, this experiment pretty much panned out well just because turns out mcdonalds paties are actually 100% beef after all (they always claimed so but honestly never really believed it lol)

Since myself & missus adopted a ketogenic diet we both lost 3 stone, my arthritic knee pain has cleared up & the missus isn't type 2 diabetic anymore, the doctor sat there flabbergasted at how well we are considering no medication whatsoever has been used.

[@turokforever007]

Once KETO really caught on "experts" started to say it is really bad for you. Seems like they don't want healthy people

[@MythAvatar]

Excellent video! I've definitely read the clear message; I'll go order 16 McDonalds burger patties and eat them every day forever. Thanks for clearing that up!

[@DuncanAtkinson]

Maybe throw in some gherkins, food for the git bacteria 🦠 😛

[@turbobros_online1561]

@@DuncanAtkinson idk what a gherkin is but you gotta feed those microbes if you are chasing optimal health IMO. A good variety of small amounts of fermented veg along with your meat seems to be very positive.

Great documentary, well researched and a sound reasoning, 10/10!

I've been waiting on your results from this for a while! So interesting to hear your take on this 👍 Very informative and love your books 😁

[@catiemonteiro7283]

Brilliant and refreshing! I've been keto/carnivore for years to manage anxiety, so I've really been looking forward to watching this video! :) Thank you for articulating this (frustratingly contentious) subject so thoughtfully.

how much do you pay for just the patties ?

[@herrar6595]

Phenomenal Job! I have to say, half way in, that in my time on youtube, I have seen few such nuanced discussions on anything really. I don´t agree with all the points, but that´s what makes it special. You have created a magnet for healthy, nuanced disagreement.

[@boohoo5419]

before even watching this.. the bread and sauce is the problem.. OBVIOUSLY!

[@FulguroGeek]

the cheese too.. eating salty beef is ok .. its meat!

[@yvves6861]

probably don’t look at this video much but i have to say this piece means a lot i’ve been working at mcdonald’s throughout high school and into college and i’ve been trying to maintain diet as well by eating the beef specifically the quarter which is fresh beef and wondered how that would fair in an experiment like this

[@davidstaunton2386]

Fascinating video, as always with Dave. Reading the comments on instagram has been quite depressing, I personally hugely value Dave’s open views and have had very positive health improvements by following some of the research threads he has started. ❤

[@trainmoveimprove]

Incredible work Dave! Gonna have to stop at 20 minutes for today, it'll take me weeks to digest all this food for thought!

[@nutzerbezeichnung]

I appreciate the general sentiment of confronting dogma(especially in a science as fraught as nutritional science) and an interest in open discussion free from personal attacks and all too common online nastiness. People should read the papers behind the headlines and realise how often these studies are ambivalent in their findings or poorly constructed. And your experiments have left me curious about the how's and why's of your results. That being said, I think some of how you framed this discussion is pretty questionable. For one, the references to Super Size Me should be more critical. The movie has been all but debunked. Spurlock admitted to being an alcoholic during the filming, which might have contributed to his bad health outcomes. He was also forcing himself to over-eat, unlike you. And studies trying to replicate his results have pretty much come up with nothing. Also, when it comes to confronting dogma: there is a real question whether there even is such a thing as an obesity epidemic. Obesity research in general is riddled with stigma and bad science. Which goes together with you suggesting that the outrageous health care spending in the US is because of high rates of obesity. It absolutely isn't, it's a function of how dystopian their health care system is. It's definetly more complex than 'People in the US have higher BMIs'. Lastly, I think your suggestion that a normal meat free diet might lead to more animal cruelty than a meat diet seems far fetched. You might have access to animals raised more humanely than the average but those cows still need to be killed. And this isn't scalable. Pointing the finger at vegetarians for the animals killed in farming is in bad faith. Most meat eaters still want food from those same fields and most of the meat they eat is fed on farmed plants as well.

[@kris575d]

Hey @nutzerbezeichnung, The points about landuse being equally or more efficient when using animal protein was also were he lost me. The references that he cites to back up that statement does not support his argument and I think he would have come away stronger if he would have left that standpoint out of his video. The world is not capable of supporting billions of carnivores, but it could support billions of omnivores who eat slight amounts of animal protein. The reason his entire statement about landuse is invalid, is very simple. Animals are also feed cultivated plant foods, and if they are not they require a whole lot more land. In fact a free grazing herd of cattle requires a minimum of 1 acre per cow. This can of course only be on suitable arable land. Right now the world has around 1.5 billion cows (According to the US department of agriculture), while the world has 3.4 billions acres of arable land(World population review), so just to meet the current demand we would have to allocate half of the worlds arable land to cowgrazing. I like some of the other thoughts in the video, but this point just didnt sit right with me. I am btw not a vegetarian, but do hold a masters degree in biology.

[@JoaoMFaria]

loved every minute of this video has it has definitely has opened my viewpoint of this subject simply by the way you can easily transmit your knowledge! Already have two other videos you mentioned about your experience on queue! cannot thank you enough for this.

[@stuffstuffington39]

When it comes to carbon lost from soil when plowed etc mentioned at about 22:20. For factory farms wouldn't it be true that the soil would still be used to make the processed food to feed the cow? Genuine question, not a statement :)

[@renciapolous]

Amazing video and experiment. It's authentic, insightful and makes such deep points not only on diets and the consuption of meat but on the whole way we culturaly accept things as general truths or standards. I was amazed at all the aspects it covered. Thank you.

[@breezyillo2101]

I didn't even realize this was Dave's channel until I read the comments lmao. Finna roll up to the crag with a no-carb happy meal

[@desperatelysending]

Thank you for sharing such a comprehensive look at your experience and data analysis. It's obviously very interesting, especially considering the bad reputation of red meat. --- It's common in all types of work, that when you do an excellent job, you're rewarded with requests to do more of it. And so here I am to do just that... it's a big ask, but I think it would be a phenomenal service to all those who are curious about this subject, for you to explore and analyze the "opposite side" of this diet experiment. You made a comment specifically ruling out a vegan diet, but what about taking on the challenge of engineering some kind of "meatless" diet to most closely approximate the results to this carnivore diet... what foods, supplements, quantities etc would be required to replace everything that you get from the meat? --- To have the same person, as knowledgeable and experienced as yourself, attempt both approaches would be incredibly interesting.

[@hbinjapan]

Sneezed my tea out in the first minute! Might try that here in Japan though I'm not sure how to say exactly and what the reaction would be to "I don't need the buns". Will Part 2 be the deep-fried haggis and Mars Bars experiment?

They’ll probably run around asking each other if it’s possible for about 35 minutes before telling you they can’t do it. 😂

Yes that's exactly what happened when I tried.

[@CG-sm6xb]

An interesting video. I do question your point about the rearing of cattle. To keep up with a very high demand for beef and dairy, most cattle are kept indoors and fed on grains. Therefore they require the ploughed up land you referred to as a downside of people consuming vegetarian diets. In fact they require much more land for the growth of grains than would be required for grains for humans. You also didn’t comment on the production of methane.

Do you keep a detailed training journal with all the information (hang weights, daily mood, bodyweight, progress on projects, etc) written out for each day? I would be curious to see how you keep track of all these variables in a way that allows you to easily go back to previous years/ seasons and see what has changed. Thanks and well done on the video.

[@darraghonuallain9954]

Excellent video, again

[@michaeldavidsonjr]

I appreciate your detailed discussion, inclusion of scientific lit, and willingness to tread into such perilous terrain. In discussing the destruction that can come from unhealthy plant agriculture, I think you neglect to account for the fact that animals farmed for food have to eat too--and they eat plants. If our plant farming needs reform, it affects both plant and animal eaters. Moreover, because cows have to eat so many plants to produce enough food for a single human meal, any negative effects from plant faming are actually compounded.
