First link, study does nothing to support the idea that a primarily carnivorous diet is in any way better and doesn’t claim to, simply that higher calorie and nutrient intake results in more/faster growth in children.

Second link, the study also does nothing to support a primarily carnivorous diet, from their conclusion: “Meat intake, or its adequate replacement, should be incorporated into nutritional science to improve human life expectancy.”

Third link, actually relevant to carnivore diet! And it’s a sample size of just over 2k, a timeline of less than 2 years, and entirely self-reported data with no external verification whatsoever.

Fourth link, also makes no claims whatsoever regarding a primarily carnivorous diet. From the conclusion: “Our study found that, for relatively healthy older adults, the consumption of eggs 1–6 times per week was associated with a lower risk of all-cause mortality and CVD mortality compared to those who rarely or never eat eggs. No such potential benefit was observed with daily egg consumption.” So not only does it not even try to recomment a fully carnivorous dier, but it explicitly states that eating more eggs resulted in no increased health benefit

You clearly just googled “carnivore diet is healthy study” and posted the first four results that came up, you don’t give a shit about what’s actually true you’re just here to push an agenda
