    100%. For example right now the meat and dairy lobby groups are pushing hard for everyone to eat for more protein than they need. Now, I have people who can’t tell the difference between a cytokine and a histone without using Google, even if it slapped them round the face, telling me they need 100g plus a day in Brotien. Its just a coincidence that this so called health advice makes those groups a lot more money.

      I’ve heard that you cannot absorb (for lack of a better word) more that 30g of protein/day (adjust for your body weight).

      Is that remotly true?

    One of my past flatmates literally self-diagnosed himself with diabetes out of nowhere and started extreme dieting - made all sugar and high-carb foods haram and even started mixing his own flour to make it “multigrain”. Since we were sharing kitchen expenses all of our meals then started involving coarse bread and either chicken or tofu at all times. Made me constipated for a while.

    I think all he really wanted was an excuse for that diet and it does seem to have worked well in him; shame it didn’t do so on me and just made me eat outside more instead.

    my boss does a “cleanse” once a month. IDK what she takes but she also believes ivermectin cures cancer, sooooo…
    Its no coincidence that she is one of the sickest “healthy” people ive met. She has no health conditions or chronic illnesses. Shes in good physical shape and doesn’t smoke or drink. Exercises most days, etc. Yet, she “cant get out of bed” or has some mystery stomach flu or something like that about once a month. Funny how that seems to line up just after her cleanses. I suggested once that she was making it worse with the cleanses but she just doubled down.
    Willfully ignorant and proud.

      as soon as you hear (X) cures cancer you know shes deep into pseudoscience, its one of the “gateway” into pseudoscience. those cleanses are likely messing up her gut microbiome causing “diarrhea, GI problems”. when i took antibiotics once he caused watery runs, and it never was the same.

      i wonder if shes getting antibiotics from a shady ass doctor, i know if you take too much you will have chronic GI problems. there something called chronic lyme, where its usually midwestern woman believes its chronic so they go to a MD that is “specialized in Lyme” to be prescribed on antbiotics for months on end, and to convince themselves they have it, they take another shady test for lyme.

      Firehouse in the USA: “right leaning straight white guys that watch FOX news” is over represented. We work 24 hour shifts and thus cook two meals a day at the station. Inevitably that means I get to experience whatever dumb-ass dietary advice the manosphere/RFK Jr. is pushing: keto, carnivore, MORE PROTEIN, etc.

          Clearly you need to spend more time around Joe Rogan watching dude-bros. There’s also several of them on supplemental testosterone: “The doctor will tell you that your level is normal but they’ve been secretly lowering the ‘normal level’ over the past several decades. If you want I can give you my doctor’s information.”

          I walked into my break room at work a couple of years ago and overheard some of my female coworkers complaining about the formula shortage. I asked if they’d ever thought about breastfeeding and they looked at me like I’d just grown a second head. I get that some women here and there might need a supplement for this, but the idea that feeding babies canned formula should be the norm is completely insane.

            Breast feeding is a huge amount of work, asking a person to do that and have a job is a big deal. Pumping breastmilk is incompatible with lots of jobs. If they have already stopped breastfeeding they may not be able to restart.

            It would be great to live in a society where breastfeeding was normal and easy. Society is crazy and women shouldn’t be criticised for trying to exist within it.

            That’s as dumb as them suggesting you take on a second job to cover the heightened cost of the formula, but the second job has to be donating blood, plasma, and bone marrow. The physical toll to make up that much extra nutrition, the (sometimes permanent) leaching of elements of your own body, the quantity of time to pump and properly clean and store and the cost of products, the emotional toll of sacrificing what used to be a fun part of your body to what for many is quite painful…

            Sure boobs are made to make milk, but eyes are made to see. How many people do you know who wear glasses? It’s more complicated than just why not breast milk?

            If women should be expected to breastfeed for 2 years, then society should be built that they can take two years off to do so. A year of breastfeeding equates to a conservative estimate of 1,800 hours, which is not far off from a full-time job that totals about 1,960 hours annually.

            In serious, most ways to loose blood and need blood infusions will loose the plastics too, so the donated blood just maintains the concentrations, the samw way it does for the other components.
            Everyone has plastics in their blood.

            But then if you donate frequently your blood will have lower concentrations due to all the previous donations, so don’t just donate, donate often.

        Yeah the dude is really wrong.

        Your body is good at filtering out hydrophilic toxins. But for just about every other toxin… Not so much. Most hydrophobic toxins and other toxins, like heavy metals, VOCs, pesticides, micro plastics, etc., are man made and your body hasn’t had millions of years to evolve natural filters.

            I’m an environmental engineer and environmental scientist and I specialize in industrial hazmat waste issues, but I recognize even I’m a bit out of my professional lane on this.

            But if you were to identify specific “toxins” that you are interested in “cleansing” there are often methods to do that. But first, I would recommend talking to a health professional. And those cleanses are going to vary significantly based on the toxin of interest.

            But your best general “cleanse” is to eat more green leafy vegetables and exercise regularly. And feel free to drink a 4oz glass of milk a couple times a week.

              I think we’re talking past each other here.

              The original post is talking about people with “a systemized non-scientific theory of anatomy and nutrition.”

              The comment that we’re responding to says,

              Anyone talking about “toxins” and “waste products” as if they’re ‘stuck’ in your body is either very ignorant, or trying to sell you snake oil. Probably both."

              The people who blog about “toxins,” as a generalized word without a specific meaning that could reasonably be replaced with “evil ghosts” in a sentence, are not interested in listening to doctors or scientists. They are “health” influencers on par with the current US secretary of Health and Human Services. I specifically called them “MAHA moms” in my previous comment for this reason.

              I would hope that all reasonably educated people recognize that there are actual toxic substances that our bodies absorb that are harmful to us. But anyone who is identifying a specific toxin, much less a medically appropriate treatment plan for removing it, is leagues away from the snake-oil peddlers this post is talking about.

              If you have not encountered these charlatans, more power to you. They used to be relegated to specific corners of the internet, but they’re becoming more mainstream with help from powerful figures in Washington.

              I, unfortunately, had a loved one who followed some of these influencers with deadly effects. It turns out that juice cleanses and energy healing can’t cure cancer.

                There are several problems with the charlatans.

                1. if you haven’t taken a science class since high school, then their advice often right. I’m amazed at how quickly the medical pseudo-science that flipped politically in my life time. I was raised in a deep red conservative Christian community and I don’t remember anti-vaccines ever being a thing for my community (we definitely had our issues, just not that one). The medical pseudo-science thing back then was firmly in the far left liberal sphere. The anti-vaxx movement was a hippy-liberal thing. (I’m not really sure when that flipped.)

                2. The medical industry -including academia- is very much at fault in burning trust. There are many instances of the medical industry intentionally withholding treatments because a different treatment made them more money. Or doctors over prescribing in order to charge insurance companies more money.

                3. A lot of what RFK jr says. Starts off good. He’s all like “Hey, we medicate too much. We should all focus on eating healthier and exercising. That’s what the government should encourage.” And even I’m like, “Yeah, okay. I agree.” Then he goes on to say “And that why you should shove a bowling ball up your butt.” That’s when he loses me.

        AFAIK, still no conclusive studies that show microplastics having an overly adverse affect on the human body. I’ve seen one linking it to lower sperm counts, but that’s not particularly bad to me. We don’t need more people.

        The big scare with microplastics is that they are everywhere and that certainly isn’t good; and I think we’re all just waiting for the shoe to drop and some study to come out that shows something majorly negative with them. But for now, there’s nothing obvious sticking out that shows an immediate concern. Which makes sense. We use plastic for so much because it tends not to react to stuff.

          The problem is that we’ll never know because there’s no control group. Everybody has them, even fetuses still in the womb. You would have to build bunkers with perfect air filtering, and then go through, like, four generations of humans to breed microplastics-free specimen, which you could then use a the control group for the rest… Only them never leaving the bunker would already invalidate the tests… So, yeah…

              Though even that is complicated by 50 or so years of nuclear weapons testing, which likely also increased cancer rates. Not to mention all that lead everywhere. Produce gradually losing nutrients because farming mostly just focuses on the big three with fertilizer and the others are being mined out of the ground and sent to landfills, septic tanks, waste processing facilities, cemetaries, and crematoriums also doesn’t help (though I’m not sure waste processing and crematoriums remove those nutrients from the cycle like the others, since the one could produce fertilizer and the other might be sending it out into the atmosphere where it could eventually end up back in the soil).

              There’s so much chaos that it’s hard to isolate causes, which then makes all the causes kinda “hide in plain sight” because they can perpetually blame the others and shit only gets worse over time.

                  Yeah, microplastics, too. And “pollution” being still broader than the list either of us have given so far. A car goes by smelling like gas? They are running their motor too rich and you’re literally inhaling unburnt gasoline. A car whose exhaust stinks but not like gas? Running too lean and now you’re inhaling various nitrogen compounds that aren’t great for inhaling. Ratio is correct? Still inhaling more CO and CO2 than normal, but everyone is doing it so there might not even be a control population to compare the effects against.

                  Oh also all the food additives that get tested for acute safety but not so much chronic (as in “will it kill you or make you obviously sick if you eat it once or a few times?” gets studied but “will eating it twice a week for 30 years have any long term effects?” is ignored).

          We haven’t noticed much in the way of short term effects, but there’s no way to know what long term effects there will be except to wait.

          In the meantime, since the effects are… unlikely to be beneficial, the best thing to do is reduce exposure as much as possible.

      There are bio-accumulative toxins that really do get stuck in your body. Lead is a good example. Not that the supposed cures being peddled by these people can actually do anything about those.

      Also, for the normal kind of toxin, the biggest factor keeping the levels in your body high is continued intake. Reducing that totally makes sense. However, you need to first have a real, based on science, understanding of what those toxins are in the first place and not just randomly blame junk food or 5G radiation, and it needs to be a permanent life style change. A two week “cleanse” does nothing. A juice will not detoxify you. (Depending on the juice, especially how filtered and how sugary it is, it may be healthy for other reasons. Standard orange juice is not, it’s way too sugary.)

    Oh how I hate the whole idea of detox and clean as it relates to nutrition. I worked at a health food store when I was young and while there was good nutritious food there, plenty of good people, the whole idea of ‘clean’ comes from a very dark place. I remember the raw foods guys and the idea of breathetarians. Like the less physical and embodied you were, the better person you were, enlightened. The idea of the physical world being unclean and something you should try to be free of, I hate it.

    It really is more of a religious idea than anything to do with physical health. I think you have to enjoy being embodied, love the physical plane of existence, to have a healthy body. Not perfect.

    ETA: OMG another comment reminded me. Also the colonics people trying to get literally clean inside, horrified at the stuff that came out of them, convinced it was toxic. I’m sure they are all dead by now.

      I read a thing recently that argued that “purity” is one of the most distinctive thematic motifs in fascistic thinking, and examined how that is a means by which people can slide into right wing ideologies from an initially left wing position.

      It was striking because it made it clock for me why there seems to be a “crunchy eco-leftist turns right wing” pipeline. To attempt to summarise some of the article and my own thoughts following it: A purity oriented framework of health situates “toxins” and the like as the Big Bad Other. Many of us are aware of how dangerous the notion of a Big Bad Other is if we’re thinking about people, but it can creep up with us in contexts like this because it doesn’t seem harmful initially. However, by thinking about health in this way, we train ourselves to think in terms of the Big Bad Other, and condition ourselves towards thinking about things in a black and white manner.

      I worked at a vitamin store chain owned by the parents of a college friend of mine (who is now worth $34 million lol - that chain has turned into a miniature Whole Foods) for a few months. I remember one customer came in because she was going through a divorce, and the cashier said “oh, you need St. John’s Wort for that”. Nobody there thought this was unusual in any way.

      Also knew a guy in college who claimed to be a Breathitarian. We caught him at the Ponderosa steak house in the next town over one night.

        Its less commonly assumed now, but “eating fatty foods makes you fat” is really not true. The “fat free” food craze of the 90s-mid 00s took the fat out of everything and added sugar to make it taste good again. And everyone got fatter. Exactly as the sugar industry planned.

      I lost a ton of weight and that gave me the courage to go to the nude beach. That day I got exactly 30 seconds of sun on my cock and that was enough to sunburn my knob. Itch/burn for days. There’s a reason it’s known as *where the sun don’t shine". Can’t imagine what it was like for the dopes that gave themselves 15 minutes under the Cali sun.

      Whilst this is true; your body does have some pretty neat tricks to maintain homeostasis; it can shift the energy budget around quite a bit to where it is needed.

      Your body will down regulate some systems to try to keep your total energy balance within what is “normal” for each person.

      Digestion uses quite a bit of energy; this is why sometimes you feel sleepy after eating; your brain has been down regulated to enable digestion.

      Another common example is when runners get into “the zone”; this is your brain prioritising the required processes and reducing the energy of other parts, putting you into a semi trance…this is so your body can maintain an energy balance.

      It is also why we sometimes feel sick if exercising hard and then eat quickly afterward; your gut is not ready for that job.

      High energy process that can be “switched off” or at least significantly reduced:

      • Brain processes (up to 25% of your energy budget)
      • Immune system (~20% when fighting infection)
      • Digestion (dependent on food 3[sugar] - 30[protein]% of food energy)

      Just because you have done some exercise; doesn’t mean you have used more total energy that day…it seems counter intuitive; but your body likely shifted energy from one thing (immune system, brain) to muscles, for the time your were exercising.

      In saying that exercising is so good for other things; physical and mental health are enhanced by exercise, there are so many good things about exercise, just don’t rely on it for weight loss.

      As the old saying goes “you can’t out run a bad diet”; you are correct, if over the long term you eat fewer calories than your body requires, you will see an effect. But your body is a tricksy beast, it will do all it can to prevent this; it is why dieting is so hard in an age of abundant food.

        Also people tend to focus too much on the “losing weight” part, as in getting the numbers down. Muscle weights more than fat, and having more muscles uses more energy; if you diet the wrong way and don’t exercise, it’s possible you lose weight but you also lose muscle mass, making it even harder to lose more weight and possibly making yourself unhealthier. Getting “thinner” and/or “healthier” might mean you don’t actually lose that much weight, or even gain some

      What do you think about keto?

      Basically it’s “ditch all sugar”, and the idea is that when you eat sugar, as it’s toxic, the body tries to use up the energy from sugar, storing the rest for later. And vice versa, if you have no fastburning sugar, the bidy have to start to rely on breaking down that stored fat.

      Of course, you cannot overcome physics, but it’s not like we don’t store everything we eat either (the body is fantastic but not like 100% efficient).

      Some say you just eat less, and it’s true that it’s harder to cook without potatoes, rice, pasta… And sugar makes you want to eat more.

      It’s fascinating because we don’t know more than around 10-15% of how metabolism works.

        ++ Keto works because its keeps insulin levels from going high, when insulin is high the body simply cannot metabolize stored fat (at all).

        Doing low calorie works by itself, but its hard mode, eating a bunch of insulin spiking meals throughout the day makes it much harder to burn through that sugar, lower the insulin, and eventually metabolize stored fat.

          Keto also works because the homogeneity of the meals induces many people to eat less.

          If you were literally forced to only eat chicken and broccoli for every single meal, eventually you would become so disgusted you would eat enough to survive, and probably not anymore.

        With every diet, named or not, the weight loss aspect always comes from “calories in vs calories out”.

        Some of them, like keto, change the way the body accesses the calories in food, but the math still holds. If your body can’t access the calories in what you eat, they literally become “calories out” when you go to the bathroom later.

        Other diets help with mentally being able to track calories better, or to just help you deal with how hard it is to eat fewer calories.

        But no matter what, conservation of mass and energy always applies.

        Tracking calories accurately is a balance between good data and time investment.

        I didn’t usually count oils and fats when I made food because I use so little. But I also wouldn’t worry much about very low calorie vegetables either.

        To be fair though my goal was to gain weight and meet macros, not to lose weight.

        But either way at the end of the day even with really good apps making counting calories way easier than it used to be, there’s still a line that needs to be drawn somewhere as to what your time is worth. If you’re in the ballpark you’re good unless you have very explicit needs to get more detailed data.

          Tracking calories accurately is a balance between good data and time investment.

          Absolutely true, and getting good data is really, really hard. In fact, the nutritional content on food labels (in the USA) is allowed to be over by as much as 20% by the FDA.

          In addition to that the processes and formulas used to calculate those numbers are also far from precise .

          The most accurate method to measure energy and calories in food is called a bomb calorimeter, Li said. The process works on the theory that when one thing releases heat — in this case, food — it’s absorbed by another, in this case whoever is digesting that food, as energy.

          To make this calculation, food scientists seal a piece of food in a pressurized, oxygen-filled steel container — the “bomb.” That container is encased in an insulated box filled with water.

          The scientists light the food on fire and let it burn completely. Then, they take the temperature of the water. They use an equation to tell them how much energy — and therefore calories — are in that piece of food, based on how much the burning piece of food raised the temperature of the water surrounding it.

          However, this is only an estimate because not everything that burns and releases energy to heat the water can be digested by a person eating it. Fiber, for example, burns in the calorimeter but will just pass through your digestive system without giving up its energy.

          Many food companies don’t even test food like this. They simply estimate the calorie content based on the number of grams of fat, carbs, and proteins in the food. Still, unless and until someone comes up with a better way to determine the calories in a given measure of food, it’s the best system we’ve got.

            I’d also be willing to bet that the actual amount of calories someone gets from different kinds of food is dependent on their gut biome, and thus variable between people. Ime you really need to experiment on yourself to get a good idea of what will make you lose weight. Same probably applies if you’re underweight and trying to gain.

      I’ll just keep repeating this, but your BMR (Basal Metabolic Rate) is not scientifically set in stone.

      While it’s accurate for I would say 90% of the population, rough estimate, there are many things that can cause your BMR to not be accurate, like thyroid issues or lack of musculature due to sedentary lifestyle or due to hormone imbalances or any number of myriad things.

      I went and had mine tested and it cost me I believe $70 at a sports medicine place, and I burn approximately 200 calories less than my BMR chart says that I should.

      So if I wanted to maintain my weight, and I ate the calories the internet says that I should every day, I would actually gain almost 20 lbs a year (a nice rough estimate is every 10 calories a day you cut from your diet you lose one pound a year).

      And as I am working on losing weight, and I’m eating 500 calories under my BMR, I’m actually only eating 300 calories under my true BMR, which means my weight loss is incredibly slow.

      So yes, while calories and calories out is true, there are external factors that make it difficult to get accurate numbers to compare against.

      Therefore calories in calories out is much simpler to say than it is to do for some percentage of the population.

        Not only is it not set in stone, it appears that your BMR is affected by what you do. If not provided with sufficient nutrition, the body seems to adapt and lowers BMR.

        Getting the numbers in practice can be difficult but that’s not the same as saying that CI/CO is bullshit, as many people do who don’t understand that it’s simple thermodynamics. If your fire isn’t producing enough heat, you add more wood. You don’t start to doubt that burning is exothermic.

          The body isn’t a fire and food isn’t wood, so the analogy isn’t a very good one.

            And even if it was, wood in a fire pit does not burn uniformly.

            The type of wood, the quality of the wood, the contents of the wood all affect how fast it burns and how hot it burns.

            Very dry pine wood burns incredibly hot and very fast, whereas damp maple may self-extinguish. It may not be capable of maintaining its own fire due to its moisture content and the density of the fibers in the wood.

            And while you can look at the whole and say this amount of wood emitted this many BTUs of heat energy, you can’t say “this amount of wood being burned should emit this amount of heat in this period of time” when you’re not taking into consideration the type of wood, the quality of wood, and even how the logs are arranged.

            Science is about controlling variables, and when you have too many variables that are not being taken account of, you cannot get an accurate scientific measurement of the results of your experiment.

            And that’s not even taking into consideration the fact that the raw nutritional quality of foods grown in the western world at least has dropped precipitously, inducing people to eat more food to get the raw nutrition they need that’s not just calories.

            We know that calories are comprised of carbohydrates, proteins, and fats, and we can generally account for those, but the nutrition, the selenium, the zinc, the iron, the calcium, the phosphates, the everything else that makes up the food that we eat. If it’s not there in sufficient qualities to meet what our bodies are calling for, then it’s natural for us to overeat to attempt to fill in those nutritional deficiencies.

            And when your brain has been fucked by not getting the nutrition it needs, and your body has been fucked by not getting the nutrition it needs, and your food has been fucked by not delivering the nutrition you need, then once you’re in that situation, it’s not as simple as, oh, just don’t eat that Twinkie.

            So calories in, calories out is the truth.

            Just like gravity is the truth.

            But knowing the math, 9.8 meters a second squared, is not enough to go to the moon.

          You have completely missed the point of my entire rant.

          Cico works, but “o” is a variable that can vary wildly from person to person, day to day based on environmental, genetic, and nutritional factors.

            I’m confused. Your original comment was worded as if it stood in contradiction to cico.

            Does not what you said just boil down to cico works, but knowing how much energy your body uses on a daily average (o in cico) is difficult to know and to not trust random values on the internet?

              The only way to find it is to eat less and less until you lose weight tbh. Cico is vacuously true.

                Cico is vacuously true.

                https://en.wiktionary.org/wiki/vacuously

                Showing a lack of thought or intelligence; vacant.

                Surprisingly, I agree with you! CICO is lacking in thought and intelligence when applied to human metabolism.

                The second law of thermodynamics requires a closed system, humans are famously open what with their breathing, eating, pooping, and peeing.

                CICO is like saying cars without fuel don’t move, so if overfill the tank you should park your car. It misses the point, and that is the hormonal drivers in human fat mobilization.

                Sugar/Carbs drive blood glucose, which drives blood insulin, which shuts down fat mobilization. Yes, you can lose weight eating only sugar, but it’s making the entire process more difficult then it needs to be.

                  I absolutely agree that cico could be very difficult psychologically and could demand health monitoring.

          Eating a tapeworm also makes you lose weight, doesn’t mean it’s healthy. Not everyone can starve themselves thin in a healthy way.

            You don’t need to “starve” yourself. That journey can be milder (though longer).

              This is what you’re not getting. Some people do. Just getting to the point of not feeling like they’re starving puts them over their calories out.

      I can’t digest pork well (it runs right through me and frequently causes vomiting), so I don’t l eat it, but if I were to follow a diet with 500 calories of pork in it, I might get 100 from it. On the other hand, I digest beans and lentils incredibly well, with no noticeable gas. I can imagine that I might actually get 110 calories from a “100 calorie serving.” It is possible to determine your caloric intake despite this variation, but because people aren’t well educated about it, they see a mismatch in the math and reality and think it’s pointless to calculate it at all instead of realizing they need to adjust it for their specific digestive system.
