| For me, it's a hard problem. For business trips, the choice is between two hours and two days, and unfortunately my body goes haywire if I don't eat some meat at least a couple of days per week (talking about 200g/300g total though. Not kilos of it). On the other hand, I'd happily take trains as more high speed lines open in my country, and reduce meat consumption to bare minimum my body can tolerate. For personal transportation, going fully electric won't be possible due to my circumstances, but I'd happily switch to a hybrid which would convert 75% of my in-city travel to electric (which I'm actively planning to do). I also work on projects which tries to reduce footprint of data centers and computation, so there's that. |
| > my body goes haywire if I don't eat some meat at least a couple of days per week Isn't this just a nutrient deficiency in whatever you were eating instead of meat? Meat is "convenient" because it's high in a wide variety of minerals, vitamins, essential amino acids, etc. that your body can't make. (The animals mostly can't make them either but guess what livestock eats.) There are plants that contain each of them, but few if any that contain all of them, and then if you're missing one you're going to have a bad time. So the problem there is almost certainly that you need to eat some different plants than that the thing you were missing is only found in animals. |

| ▲ | jandrewrogers 2 hours ago | parent | next [-] | | I can't speak for the OP but it is well-established that there are significant genetic adaptations to the amount of meat in the diet, or a loss of genetic adaptation for metabolizing some plant staples. This is no different than the genetics that cause significant variation in the ability to metabolize legumes, lactose, alcohol, etc. Local optimizations. There are ethnic populations that have reduced capacity to efficiently metabolize some plant-based diets due to thousands of years of selection pressure (or lack thereof). A diverse plant-based diet won't kill them, they simply lack the enzymes to have a good experience with it because for thousands of years they had little use for those genes. It is a relatively small population globally, as it tends to coincide with regions that weren't conducive to supporting large populations thousands of years ago. The current distribution has significant overlap with the developed world though. I have to imagine that someone with meat-adapted genetics is going to suffer quality of life issues on a purely plant-based diet. Everyone has a set of foods like that. | |

The gut microbiome is impacted by your food choices, varies from person to person, and can have severe impacts on your overall health. | |

These aminoacids and compounds are the ones which boosted our brain capacity and allowed us to evolve to that point. I eat (and like to eat) tons of veggies, yet I feel my brain capacity declines and I crave esp. meat if I don't eat it for a long time (for two weeks or whatnot). As I said, I don't need two ribeye steaks per week. My body is very good at signaling what it needs, and I prefer to listen to it. What I eat is Mediterranean cuisine 99% of the time, and it's pretty well balanced, yet eliminating meat is not possible for me. So, my diet is not junk food peppered by meat. It's mostly veggies and legumes (beans, lentil, whatnot), peppered with meat. Yet, I need it, and this is something I tested over and over more than two decades. On the other hand, my wife is completely opposite of me. She can go a month or so without meat. So, not every person is the same, and assuming that every human being works the same is a big mistake made by modern medicine. For example, my brain chemistry is also different and I consume B12 much more than a typical human, so I need to use B-complex supplements more. | | |

Notice that many of the plants high in some of these aren't that common, e.g. what percentage of people regularly eat pumpkin seeds or spirulina? > So, not every person is the same, and assuming that every human being works the same is a big mistake made by modern medicine. It's not that you need the same diet as every other person, it's that you have to eat the specific things you need, which a random selection of plants may or may not contain in the right amounts. > For example, my brain chemistry is also different and I consume B12 much more than a typical human, so I need to use B-complex supplements more. B12 in particular is a pain because it's only produced by bacteria (commonly found in soil) so the options are unwashed vegetables, meat from animals that eat unwashed vegetables, or supplements. And on top of that because of the way it's absorbed, a B12 pill either has to be taken multiple times a day several hours apart or has to be 100x as much to make up for the absorption rate falling off a cliff after a threshold amount which is below the RDA. |
