I think most people are on board with diet plausibly being a significant lever for improving mental health, and keto can be a way to do that, but the meat-heavy way most people implement keto massively increases risk of cardiovascular disease. We have an overwhelming mountain of evidence that saturated fat intake from animal sources above a certain threshold percent of one's caloric intake causally increases risk of heart disease through well-characterized mechanisms and that reducing one's intake below that threshold causally improves health. https://www.barbellmedicine.com/blog/a-basic-guide-to-cholesterol-part-2-myths-misconceptions/#_Toc92630813 https://www.barbellmedicine.com/blog/a-basic-guide-to-choles... Likewise the benefits of a high fiber diet are also overwhelmingly documented, and it's a rare person for whom it isn't beneficial. Your doctor can tell you if you're one of these unlucky people. You can eat a keto diet that's low in saturated fats from animals and high in fiber, but that's rarely done and most of the health benefits from keto is from the increased rate of adherence to a diet that makes it easier to stay in a caloric deficit.
