Just about any diet can cherry pick bio markers that may improve after starting it. But that is not a valid scientific method to determine its true impact on health. Neither are anecdotal claims.
Several have mentioned that plants are bad for humans. This is the probably the most ridiculous idea ever posted on TOV. And anyone who believes that is placing their prejudices above overwhelming rational and science based evidence. Our bodies need fiber and animal protein has none. Only plants have it. And most of the vitamins and minerals you receive from eating meat is because the animals get them from eating plants or from being exposed to water and soil like our ancestors were when they gathered food in the wild. There only a few possible medical reasons to avoid some plants such as the rare case of epilepsy.

There is a site, pubmed.gov, which posts most of the medical literature and studies from established and credentialed organizations. Any medical or diet recommendations should should be accompanied with multiple citations from this site or other renowned medical organizations. One advantage of meatless diets not often discussed is the it takes 20 times more water to produce a calorie of protein from meat than it does a plant.

And what about heart disease? There is only one program for heart disease reversal that is reimbursed by Medicare.
Ornish Lifestyle Medicine The key part of it is a plant based diet. Also the Cleveland Clinic which is considered the #1 hospital for heart disease also has a program to reverse the disease for those who are not candidates for surgery.
The Esselstyn Heart Disease Program | Cleveland Clinic Both programs have many years of data to validate them. Is there a carnivore program for reversing heart disease that has decades of data to validate it? Please share.
And if you have Type 2 diabetes? A balanced whole food, plant based diet in most cases reverses that.

Kidney disease too.
Conclusions: Higher adherence to healthy plant-based diets and a vegetarian diet was associated with favorable kidney disease outcomes.https://pubmed.ncbi.nlm.nih.gov/31023928/
The bottom line is that our ancestors primarily ate plants because that was available which is why we don't have the type of teeth and intestines to eat raw meat.
If you want to return to your ancestral diet, the one our ancestors ate when most of the features of our guts were evolving, you might reasonably eat what our ancestors spent the most time eating during the largest periods of the evolution of our guts, fruits, nuts, and vegetables—especially fungus-covered tropical leaves.

To be fair, there are credible studies out there that suggest that the Mediterranean or similar diets also have beneficial health benefits. But all of the blue zones receive most of their protein from plants.
