A low cholesterol diet ages you more quickly.
Saturated animal fats are the best source of energy.
Carbohydrates are non-essential and are metabolic poison.

There is a lot of variations in humans biology from one another. One size doesn’t fit all when it comes to diet im afraid. But i think there is some validity to your clam. Especially for ethnic populations living near and around the Arctic circle.
A carbohydrate based diet is inflammatory and will eventually lead to insulin resistance and type 2 diabetes for anyone. How long that takes to develop depends on a number of biological factors, but it is metabolically damaging to everyone.
If your ancestors have been eating grains for 10k+ years then you are likely more biologically equipped to process them, as opposed to people descended from a hunter/gatherer population. That's why the rate of type 2 diabetes is so much higher today in the native American population for example. But a carbohydrate based diet isn't really good for anybody.
I've come to the conclusion that diet is a spectrum. Evolutionarily, carbs were a rare treat as most plants are toxic (incl. oxalates, phytic acid, lectins etc).
Based on carbon analysis of human remains before the agricultural revolution (approx. >7-10k years ago) it has been shown that most food (if I'm not mistaken >60%) were animals. Besides these facts there are other observations that support the strong case of humans being carnivore such as anatomy of the gut (enzymatic digestion not fermentation digestion), small entestines make up most of the gut allowing for the digestion of lots of nutrition in a short time (unlike herbevores that graze all day), also brain development which has required and still does need lots of nutrients and energy.
There are no interventional trials that proof that meat has negative health effects or saturated fat is causal to cardivascular disease, not even a mechanism exists. Furthermore, no evidence for plants or a plant-based or even vegan diet to be superior, on the contrary. The nutrient profile of plants is proven to be significantly lower than animal foods, also driven by the plant toxins (anti-nutrients) that inhibit digestion and absorption of protein and especially minerals in the gut. There is just much more money to be made in plant-based foods because these are mostly refined and processed foods. Animal foods are much less processed or not at all.
Hence, my conclusion is that the optimal diet is made up of mostly animal foods. Plants (carbs) can be added based on individual desires. They are not essential. That's the spectrum.
That's my current understanding of the diet debate after investing maybe 500h of research.

There are very few proper double blind studies on the subject, but there is a mountain of anecdotal evidence of people curing all sorts of metabolic disorders by adopting a carnivore diet. Research must be pursued in this area, but there are already a lot of signs that this is the right way to eat.
True. The only radomized studies are short term with a specific focus. Hence, these can't really conclude on all-cause mortality/longevity impact.
For this it would require to put similar people into a lab for a very long time/life-long.
This can be done and has been done with animals, which again, are not humans and hence results may not apply.
