Sure thought about it too! But it seems there is more data needed, more research in this direction.

That's what I've been thinking ever since reading Deep Nutrition! And this seem to only have gotten worse in the past 1-2 centuries. The number of cases of gluten sensitivity has increased dramatically, and people are getting sicker and stupider by the generation... GMOs, vegetable oils, refined sugars and flours, nutrient-depleted foods, countless harmful and potentially harmful chemicals, etc. etc. Who knows what else is going on.
It is an indisputable fact that humans crave fat
[...]
Why do we crave fat so much?
It's because animal fat is the primary constituent of the evolutionary human diet.
Our guts.
It takes a much larger gut, and much more energy, to digest plant matter and turn it into an animal than it does to eat an animal and turn it into an animal. This is why herbivores have large, complicated guts with extra chambers (e.g. the rumen and abomasum), and carnivores have smaller, shorter, less complicated guts.
The caloric and nutritional density of meat allowed our mostly-frugivorous guts to shrink so that our brains could expand - and our larger brains allowed us to become better at hunting, scavenging, and making tools to help us hunt and scavenge. This positive feedback loop allowed our brains to grow from perhaps 350cc ("Lucy") to over 1500cc (late Pleistocene hunters)!
In further support of this theory, the brains of modern humans, eating a grain-based agricultural diet, have shrunk by 10% or more as compared to late Pleistocene hunters and fishers.

99,99% of our genes were formed before the development of agriculture.
S. Boyd Eaton, MD, Medical anthropologist
As a species, we are essentially genetically identical with respect to genetic expression, regardless of blood type, to those humans living more than forty thousand years ago. Our physiology is fundamentally the same as that of people from the Paleolithic Era, which refers to the human evolutionary time period spanning from roughly 2.6 million to about ten thousand years ago-before the dawn of agriculture.
(emphasis mine)Recent estimations assert that agriculture was not widely implemented in Europe untill little more than two thousand years ago. By most accounts, it takes roughly forthy thousand to one hundred thousand years for human genetic expression to adapt significantly to such a major change. We have yet to physiologically adapt to the agricultural revolution.
Probably you are right ( still not too late), IF No other external things happens to the human evolution for next 30 to 100 thousand years. It's already too late for repairing this problem for majority of the population. It's interesting C's says these carbon based enzymes, DNA contains, is effected by very low frequencies. We swim in the so much of radiations, very difficult to control( for most of the masses).(emphasis mine)Recent estimations assert that agriculture was not widely implemented in Europe untill little more than two thousand years ago. By most accounts, it takes roughly forthy thousand to one hundred thousand years for human genetic expression to adapt significantly to such a major change.

Maybe i am misinterpreting something here or maybe the change process is still in progress and we're not too late.

But isn't one of the major points of low carb high animal protein&fat diet the fact that our genes are almost the same as our ancestors' long long before agriculture ?

However maybe this 99,99% (which is an approximation i guess) and the remaining 0,01% is the key, and what we're talking about here.

Well epigenetics may play an important part. We may have the same genes in many cases but their expression is controlled by other factors such as dietary and environmental toxicity. In other words, the DNA is literally damaged during the lifetime of a person.

Yeah. Our genes are pretty much the same as they were 30,000 years go, but that's not the same as their expression. The healthy expression of our genome relies on adequate nutrition. But when our bodies get poison instead, it tells our genes that something is wrong, and they change their expression to adapt to the information they're receiving from the food. So a mother's epigenetic expression may be changed for the worse, and those changes can be passed down to her offspring.
I had this same experience this week when I was sent an article where a Russian (again) scientist, Pjotr Garjajev, had managed to intercept communication from a DNA molecule in the form of ultraviolet photons -- light! What's more, he claimed to have captured this communication from one organism (a frog embryo) with a laser beam and then transmitted it to another organisms DNA (a salamander embryo), causing the latter embryo to develop into a frog!
Source: https://www.sott.net/articles/show/242683-DNA-Discovery-New-Type-A newly identified form of DNA - small circles of non-repetitive sequences - may be widespread in somatic cells of mice and humans, according to a study in this week's issue of Science. These extrachromosomal bits of DNA, dubbed microDNA, may be the byproducts of microdeletions in chromosomes, meaning that cells all over the body may have their own constellation of missing pieces of DNA.
[...]
Anindya Dutta, who studies DNA replication at the University of Virginia, and his colleagues were aiming to investigate intrachromosomal shuffling of genes in mouse brain tissue - where recombination at homologous sequences could create extra loops of DNA - but the widespread nature, size, and sequences of the DNA they turned up surprised them.
After purifying the nuclear DNA from mouse brain tissue samples, the researchers targeted and digested the linear DNA, leaving only circular pieces behind. After enriching and sequencing the circular DNA, the scientists saw that they the circles tended to be small, most 200-400 base pair long, and non-repetitive. Dutta argues that this distinguishes them from previously characterized extrachromosomal circles, like small polydispersed DNA, which are often enriched for repeated sequences. They repeated the experiment with other mouse tissues and human cell lines.
Going back to the linear DNA they had originally discarded, Dutta's group was able to correlate microDNAs with specific locations where microdeletions had occurred, suggesting that bits of DNA were being excised from the genome and forming independent circles. If true, that would mean that somatic tissues are subject to a higher and more widespread degree of mosaicism than previously thought, said Dutta, meaning that the genomic DNA in the cells of a given tissue don't all match.
It's unclear what processes underlie microDNA formation, but it's most likely they occur during DNA replication or repair. Beyond that, the researchers determined that microDNAs are rich in cytosines and guanines, and tend to cluster at the 5' untranslated areas, exons, and CpG islands. To Dutta, this information suggests the possibility that nucleosomes important for gene regulation may be involved. These tend to be fall in the 5' end of genes, and DNA wrapping could explain microDNA size, which roughly corresponds to the length of DNA entwined on a nucleosome. What DNA repair processes are being used to produce microDNA is ripe for investigating, said Dutta.
