There are some studies on it, but I'm not the best person to point you to them, or argue their merits. I have a three-fold approach to it, and I may be wrong, so don't take my word as gospel--
1. ----Our body chemistry is entirely raw, so no cooked molecules are created or used internally. They are foreign. This has been true for every species on this planet, until about 100-250 thousand years ago, when humans started cooking some of their food. As such, it makes sense that our bodies would be MUCH better able to recognize and easily handle raw foods. Why would something that we've been eating for hundreds of thousands of years (raw meat/fat) be disease-causing? We have evolved to eat it, just like chimps have evolved to eat fruit, and dolphins have to eat fish.
2.--- Meat is the only food available in very northern/cold areas, versus the tropics. Animal fat is a very warming food, generally, and eating locally and in season makes evolutionary sense. As well, humans have probably been eating at least some fruit for a long time, tropical fruit, specifically. As such, it makes sense to moderate the eating of meat/fat in warmer weather/climates. Granted, there are African groups like the Masai who eat very little carbs/fruits, but they are the exception. Common sense would tell you that eating more carbs/fruit in warmer weather/climates is probably a safer bet.
3.--- Saturated fats liquefy at higher temperatures, and don't have a precise melting point. If you're worried about clogged arteries, then it makes sense to avoid eating them in extremely large amounts, especially in colder weather. Saturated fats of both types, animal and plant, are more common in warm weather/climates, anyway, which refers back to my earlier point about eating locally and in season.
All of these have to be balanced with whatever you find works best for your health. We're empiricists around here, anyway, at least when it comes to diet, so results ALWAYS get favored status over theory in this forum. Learn the science, do your thinking, but ultimately you should pay attention to your own health, including blood tests and other objective measures of health.
I had a bad lipid profile on my blood work about 2.5 years ago, when I was eating very low carb, lots of fats, and I got scared and starting eating more fruit and less fat. My next blood test was a lot better, too. However, I was eating a lot of coconut oil and raw bacon, as well as some raw sausage, and I have a sneaking suspicion that the bacon and sausage were not from pigs eating a healthy diet. So, whatever.
I now get most of my animal fat/protein from wild seafood, anyway, which is guaranteed to be high in nutrition. I also do eat fruit in moderation, still. YMMV, though.
Most of us do eat somewhere roughly in the middle between raw vegan and raw ZC. We don't have many longtime extremists on that spectrum here, because most people don't find the extremes workable, long-term. THAT'S useful info, too, for what it's worth.
Good luck, and feel free to ask more questions.
