There is a long list on this website of toxins created when meat is cooked; it's also said that nutrients are damaged by cooking so as to be less bio-available which might eventually cause deficiency disease. Cooking is no remedy.

However, I can  imagine a subtle poison created by the new world order/evil creeps of your choice and added to meat  which can only be neutralized by cooking.
Maybe this is why raw meat dried for only three hours tastes so much better than fresh.

I tried cooked palaeo before trying rawpalaeo, and it was an absolute disaster. It turned out that I had severe reactions to any cooked animal foods but not their raw equivalent. I suspect that for most people it's the same, that they find the raw component to be more importan than the palaeo component. For example, a lot of people have reported quickly becoming  fertile after years of infertility, simply by switching to raw dairy, one doesn't come across that kind of thing with cooked-palaeo to the same extent; conversely, while cooked-palaeodiets have  beneficial effects on a few auto-immune diseases of the modern age, those effects are often quite limited in scope.

I spent a few weeks eating cooked paleo on my way to eating raw paleo. I did notice some of the benefits eating cooked paleo but I had a voracious appetite. Eating the meat raw I'll eat less than half the volume I needed to when it was cooked and I feel better for it (both lighter and healthier). This was enough to convince me that this is a healthier way for me to eat. Less impact on my digestion allows my body to heal as best it can.
FWIW I notice much the same difference in satiation between fresh raw meat/fat and previously frozen raw meat/fat. Something is damaged at the molecular level and if I want to gain the most I can from the food it needs to be fresh and raw. Fat is especially noticeable in this regard (some previously frozen fat is just nasty compared to the fresh equivalent).

I did cooked Paleo for about 4 years, then VLC mostly-cooked Paleo and gradually moved to mostly-raw carnivore (just low-heating tallow to 130F now and sometimes eating the suet and marrow raw, trying to get more accustomed to it). My biggest benefits seemed to come from eliminating the following foods, roughly in order of importance, with the most important first:

gluten
carbs
dairy
legumes (soy, peanuts, etc.)
grain and legume fats
nightshades (peppers, tomatoes, etc.) and vegetables not edible raw
acidic foods
vegetables edible raw
seed and other plant fats
cooking and processing (canning, salting, preservatives, etc.)
nuts, seeds
berries
spring greens

I seem to get more benefit from raw than Lex but much less than Tyler, so between the three of us you get somewhat of a spectrum of experience. I would guess that not cooking adds another 6-10 percent health benefit for me. I don't get sick when I eat cooked meats/fish and I don't like the taste of raw more than lightly cooked except for ground red meat and I still prefer the taste of cooked fish to raw, but I notice that I don't get the same feeling of well being from cooked meats/fish/fat as I do from rare grassfed/wild. I also don't sleep quite as well or feel quite as perky and happy overall. It's not very scientific, but it's significant enough for me that it's very uplifting.

I also notice that I burp much more if I raise the heating temp on my tallow from 130 to 190 degrees Farenheit. At the Paleofood forum I think I told William, Tyler and everyone in general that I didn't see a need for me personally to eat raw, though I was openminded about it, but I eventually tried it and found that it did provide me with significant benefits.
