the presence or absence of carbs has a huge effect on whether or not fat and salt will make you diabetic or fat. keto works for that reason, and also for the satiation factor; fat is the most satiating macronutrient (although it's certainly possible this varies by individual; i would still challenge you to overeat on keto to the point you gained substantial weight - i thought i've been overeating for weeks and it turns out i've lost 5 lbs 💀)
as with any diet, your health depends on still getting all of the critical nutruents you need (protein minimums, fat minimums, specific amino acids, vitamins, minerals), and some of that requires more management on keto (sodium, potassium, and magnesium usually require supplementation, ime; fiber is a good call as well, depending on your intake of leafy greens)
your link about keto just links to... this post, it seems like, so i can't say anything in response to it. but keto is a sustainable and healthy long term diet. i have lived it for about 9 years. i would probably agree we have a toxic food environment (your guy was way too condescending and sarcastic for me to tolerate, sorry), but i would say keto is a very good diet for adapting in a healthy way to this toxic food environment
unfortunately, it would be difficult for me, personally, to follow an entirely plant based diet, partly based on satiety and partly because i'm allergic to soy. i also suspect i wouldn't tolerate plant based carbs much better than i tolerate other carbs, as someone who suspects he's been self-treating diabetes, possibly for a decade (rice and potatoes are plant based and they definitely still fuck me up lol)
additionally, i have concerns about your knowledge on the subject. satiety is a very important subject when it comes to food health, which we've discovered with recent studies and the advent of GLP-1s, and you don't mention it at all in your post (especially given, you do talk about meds in your post?), so i don't know if you really have all the knowledge you should when speaking on this subject. a pharmacy tech does not specialize in nutritional science (not that i do either, but i at least live and read about this shit)
finally, i will say that keto, while being a good diet you can do long term and healthily, is not for everyone. not everyone can survive the 2-4 week period of initially weaning yourself off carbs. that's totally understandable, and for those people, it would be better to focus on whole food, nutritious meals, exercise, and calorie management, along with the advice of a doctor and any medications they may need. a plant based/whole food based diet may also help, but has similar compliance requirements and probably issues that keto does
at least keto lets you have treats, as long as they're not carbohydrates lol
grilling me for sources when you link one study that doesn't even mention keto is crazy. and it's very hard to take you seriously when you keep linking a literal diet agency who profits off the exact narrative you're pushing, it would be a LOT better if you stuck to your arguments alone and didn't link them
(the presence or absence of carbs has a huge effect on whether or not fat and salt will make you diabetic or fat) so the foundational lecture about this is "sugar: the bitter truth" by robert lustig (https://www.youtube.com/watch?v=dBnniua6-oM). regrettably, it's a lecture which is 90 minutes long (and gets quite in the weeds with the biochem), so i'll summarize it for you (although it's a very good watch, he's both smart and a fantastic speaker):
overall, the argument lustig makes is that the healthiest diets are either (in energy) all carb or all fat. so, you'll note that i'm not actually shit talking a (whole-foods*) plant-based diet. i think it's probably good and just sounds really miserable to be on (same with any carb-based diet); but, in my opinion, healthiness is just about finding the type of misery you can live with. it turns out my preferred misery is no carbs. if yours is no fats, or only plants, i'm not gonna stop you. good for you
in fact, i think it's significant to, here, point out that one could do vegetarian or vegan keto; and i don't think many people would argue with you that a plant-based keto is probably healthier than an animal-based keto. it's just really hard; and looking at the risks of metabolic syndrome that folks who typically go keto have to weigh (they have a typical profile of: not having good impulse control when eating, suffer from little satiation when eating high carb foods, tend to really enjoy junk food) - the animal-based keto wins out hugely as something that's both healthier and practically maintainable
you wanna go tell people on keto to eat more greens? please, be my guest. i'll join you
(fat is the most satiating macronutrient) honestly, this seemed like conventional wisdom to me. i didn't think we were going to argue about this- what's more satiating, a shot of heavy cream or literally any carb of comparable energy level? but i also think this probably varies by individual (please note my quote from my last post "although it’s certainly possible this varies by individual"); however, for the average person, i think it's probably difficult to overeat fats; and it's easy enough for the average person to overeat carbs. these are basically stereotypical truths lmao
anyways, this does appear to be a generally supported statement, even if my personal experience leads me to think it's probably still varies more by individual:
and a lot of it probably has to do with your statement:
i want to close out by saying that the choice you're framing here between "plant based diet" and "keto diet" isn't a real choice. the choice most people who go on keto are making is between "horrible shitty diet that will kill you" and "keto". plant-based, in itself, is a horribly unreliable guideline when even rice and potatoes can make you sick; there are plenty of processed "plant based" foods which are also just garbage. it's just not a guideline that will work for many people in the keto group
you can (kind of) make a stronger argument by saying "whole food plant based diet", but then you lose out a bunch of people who don't have time to cook or don't like plants very much; that, in combination with "rice and potatoes are still very sugary", means that you actually have to have quite a restricted diet on top of it being "plant based" to execute it correctly
this is not the case with keto. no carbs. that's it, that's the rule
unfortunately, the long term evidence that keto is safe or unsafe is hard to come by. it's not really been studied a lot; it's still relatively new and the populations that they would study tend to drop the diet due to non-compliance (i.e. they wanna eat carbs). so yeah, like, maybe it would be more accurate to say "we don't really know" rather than "it's safe" or "it's unsafe". i think it's fairly easy to say it's better, even long term, than the shitty diet we would otherwise be eating, so i still generally advocate for it. i don't think people should not do something that improves their overall health, just because it might be bad like 20-30+ years down the line. it will almost certainly be better than how they would get there otherwise
