  • I don't think the McAllisters were in union jobs. I think they were pretty high up the tier of management.

    People talk about union jobs going away, but don't forget, non-unionized middle management has totally been gutted by outside consultants over the same time period. So the changes in the workforce have hurt the earning power of both the line workers and the middle managers who used to make up the middle class.

  • Up in horsey heaven, here's the thingYou trade your legs for angels wingsAnd once we’ve all said good-byeYou take a running leap and you learn to fly

  • Sauropods had hollow bones and air sacs all throughout for lightweight structural support. You can't just compare sizes and assume similar density as elephants or other large mammals.

  • The "mental illness" and "plumber" categories can actually add up to be more than 100%.

  • If you take 100 joules of electrical or chemical energy, and then direct them to a heater in a house, it'll create about 100 joules of heat. That's 100% efficiency.

    But if you use the 100 joules of energy to run a heat pump, it might bring in 300 joules of heat into the house. That's 300% efficiency, when measured locally at the place you actually care about (inside the house). Zoom out and laws of thermodynamics still make it impossible to create more energy than was put in, but if you look at just the part you care about, it's possible locally.

  • start supporting serious nuclear energy to drive down electric costs

    Eh, I can see a resilience based argument for why we need nuclear, but building new nuclear is never going to be cheaper than solar or wind.

  • Why no, I am not a vampire

    Oh and you probably don't want us driving wooden stakes through your heart either, huh?

  • Yeah but if some direct combustion of a fossil fuel is cheaper than electricity, then the actual dollars per unit heat will be cheaper with a fossil fuel source.

  • Yes, but that's why heat pumps in this country are typically paired with auxiliary electric heat.

    Yes, and although it's not very efficient to have auxiliary electrical heat, that's a small percent of the overall year.

    If you live in a home that hits -20C for 20 days per year, that's really cold! But you'll probably need the heater on for about 180 days per year at that point. Putting up with less efficiency for 20-30 days per year is still a net gain if the other 150 days of heating makes up for it.

  • What's the charge? Eating a meal? A succulent meal of loaves and fishes?

  • But my French toast slaps now.

  • Let other people enjoy their preferences. Some people get very particular about console/IDE fonts, keyboard switches, T-shirt fabric blends, fork shape, guitar string material, etc. Others like fashion and style. Some like architecture and interior design. Let people enjoy things, and get deep in the weeds on minute differences if they want to.

  • I've set up workarounds in my own life. Elsewhere in this thread there's people talking about forgetting to pay bills, versus bill pay. That's what I've done (and in some instances, have reminders on my phone set up to periodically remind me to do the things that can't be automated).

    I've also steered my social relationships and my career to be more accommodating of my brain. I'm with a wife who doesn't mind (and in some ways finds it endearing), and can help me fill in some gaps. I have a career where jumping around from topic to topic helps me seem well rounded, and where occasionally showing how I've done a deep dive into something persuades my colleagues that I've got great attention to detail (I do, but only on some things).

    My ADHD might be the same as it's always been, but my life has been set up so that it's all low consequences. The guardrails and safety nets are in place, and I can just be.

  • This particular linked study, that is the basis for this thread, limited itself to only unprocessed red meat.

  • There's three metrics to think about:

    • Actual number of years reduced/increased
    • Actual probability of that change in lifespan
    • Statistical certainty that the trend we observe is actually linked to the variable we're studying.

    Russian roulette (traditional 1 round in 6 chambers) in a hospice ward (where everyone has been given a prognosis of less than 6 months to live) would be a very high certainty of shaving months off the life of 1/6 of the studied population. In the grand scheme of things, that's not a very high risk. But at the same time, we can look at it and say "yes, shooting oneself with a revolver is very bad for health." Putting a more or less deadly round in the chamber is probably not going to be a hugely significant change in outcomes, even if we can objectively say that one is better or worse for the person's health than the other.

    Almost all dietary/nutrition studies involve much smaller swings in lifespan or health conditions, probabilistically over a smaller portion of the population, with less statistical certainty in the observations. But the science is still worth doing, and analyzing, because that all adds up.

  • This study shows inflammatory markers are increased on a ketogenic diet: https://pmc.ncbi.nlm.nih.gov/articles/PMC6922028/

    This rat study shows increased senescence in heart and kidneys in long term ketosis: https://www.science.org/doi/10.1126/sciadv.ado1463

    However, Cholesterol is not a disease - its essential for life - the concern has never been cholesterol but atherosclerosis - if someone has elevated LDL, undamanged and unglycated (as on keto) and they are concerned they should get a CAC score so they can see their actual plaque burden.

    What you're asking for is being studied. Here's a meta study from 2013:

    However, one established risk factor of CVD, i.e. LDL-cholesterol, still turned out to be harmfully affected by the VLC regimen, most probably attributable to the larger amounts of saturated fat in the diet(Reference Bueno, de Melo and de Oliveira1). In their discussion, the authors stated that future meta-analyses should investigate the impact of low carbohydrates (LC) v. LF on other important pathological markers, e.g. endothelial function, in order to further assess the safety of LC dietary therapies.

    This is reasonable, since evidence from prospective cohort studies has shown that endothelial dysfunction represents an independent risk factor for the development of many CVD including atherosclerosis(Reference Inaba, Chen and Bergmann2). We, therefore, carried out a meta-analysis to compare the effects of LC and LF regimens on flow-mediated dilatation (FMD). FMD of the brachial artery is a non-invasive measure of endothelial function, furthermore reflecting the local bioavailability of endothelium-derived vasodilators, especially NO. Inflammation of the endothelium is regarded to play a major role in the destabilisation of atherosclerotic lesions, therefore paving the way for future CVD events(Reference Inaba, Chen and Bergmann2).

    Their results:

    In our meta-analysis, LC dietary protocols were associated with a significant decrease in FMD when compared with their LF counterparts. A recent meta-analysis of observational studies including a sample size of 5·547 subjects has observed that a 1 % decrease in FMD is associated with a 13 % increase in the risk of future cardiovascular events(Reference Inaba, Chen and Bergmann2)

    Along the same lines, here's another study with arterial measurements that shows reduced blood flow and arterial function for those who stuck with a high protein diet: https://journals.sagepub.com/doi/10.1177/000331970005101003

    Look, none of these studies are, standing alone, enough to really change things. But it seems to me, from the outside that you're cherry picking your own results to justify carnivore diet.

    The high carb versus low carb discussion is complicated and has a lot of factors at play. But the evidence for animal versus plant based low carb suggests that animal product diets are more harmful than plant product diets of similar macronutrient profiles.

    Moreover, the overall trends show that those who eat a lot of whole grains (which are, by their nature, high carb plant based foods) have lower mortality than those who don't. The same is true of those who eat a lot of fruit (again, high carb plant based food).

    Trying to tease out which of a million variables is truly responsible for cardiovascular health isn't easy, but a lot of the overall trends can be seen:

    • Whole grains good
    • Whole fruit good
    • Red meat bad
    • Cured meat really bad
    • Seafood good
    • Legumes good

    Now, you can quibble with confounding variables, but at a certain point trying to argue that minutiae starts looking like religious apologetics, really cherry picking examples in favor while ignoring examples against. Coming up with a coherent theory of "fiber not important" or "the foods our genetic ancestors ate are somehow bad for us now" is an uphill battle, and I'm not convinced that the carnivore diet is anything more than a scam designed to sell books.

  • The injections work by causing your brain to want to do the things that you're describing. Adherence to a plan is the hard part, and the drugs tend to make people naturally want to stick with that plan, by literally making it more desirable than not sticking with it.
