Human ancestors like Australopithecus – which lived around 3.5 million years ago in southern Africa – ate very little to no meat, according to new research published in the scientific journal Science. This conclusion comes from an analysis of nitrogen isotope isotopes in the fossilized tooth enamel of seven Australopithecus individuals. The data revealed that these early hominins primarily relied on plant-based diets, with little to no evidence of meat consumption.

    You’re setting up impossible criteria for what studies you will accept as evidence against your position by saying you will only accept RCT’s with all-cause mortality as the end point as evidence. Like I said, nobody does this for studying diet…

    You seem to have a double standard for what qualifies as sufficient evidence against your view vs. for your view, as evidenced by the fact you think that the context of a keto or carnivore diet would completely reverse clearly evident trends despite a complete lack of evidence. Where are your RCT’s with all-cause mortality as an end point studying the keto diet? Where are your RCT’s showing that increasing LDL-C and apo-B does not increase CVD risk over lifespan-scale experiments?

    You conveniently chose to ignore the Mendelian randomization studies on LDL-C and apo-B.

    Your view on ldl-c and apo-b goes against expert consensus (https://www.lipidjournal.com/article/S1933-2874(24)00240-X/fulltext, https://www.jacc.org/doi/10.1016/j.jacc.2022.07.006, https://pubmed.ncbi.nlm.nih.gov/28444290/), there is very compelling evidence that both, especially apo-b, have a causal role in long-term CVD progression.

    While the conversation has been interesting, I feel that continued exchange will not be particularly productive.

      Again, I’m not trying to change your mind. I frankly am happy you have chosen a different path.

      Where are your RCT’s showing that increasing LDL-C and apo-B does not increase CVD risk over lifespan-scale experiments?

      I literally linked you a RCT in the above post showing LDL being protective for all cause mortality

      Mendelian randomization

      I do not consider this any more serious evidence than observational. Randomizing observational studies is an interesting way to determine where your next research should be, but not to draw conclusions.

      While the conversation has been interesting, I feel that continued exchange will not be particularly productive.

      Agreed. I don’t think either of us are making progress with the other. And that’s okay. We can both exist taking separate choices.

      keto or carnivore diet would completely reverse clearly evident trends despite a complete lack of evidence.

      This is unfair, because I have provided that information above, I’ve read all of your links. I don’t think you’ve read any of mine. To be quite frank, I think you’ve already decided what the right outcome is, you’re going through the motions to overwhelm me, but not to engage in an actual intellectual discovery. We’re not having a conversation, you’re throwing papers at me. That’s why we’re not progressing
