While you're spot-on with getting a large percentage of your calories from fat, in the long run large amounts of animal fats from meat, eggs and dairy will raise your cholesterol levels and cause a lot of inflammation from free radical damage. If I were you, I would switch to unprocessed olive, grape, flax and canola oil. These oils have the 9 calorie per 1 gram ratio, but remove cholesterol from your arteries. They are also unsaturated, which means they release very small amounts of free radicals.
You're right on target with fasting as well, people who fast at least one day out of the week have a longer lifespan on average than those who don't. There are several metabolic pathways that are affected by fasting that involve the aging process.
I'm really big into a raw diet, and have done a lot of studying about the micro nutrients necessary for the human metabolism to efficiently function. As others have noted, removing grain from your diet is a good thing to do most of the time. Be careful though, as I removed grain from my diet for a couple of years and permanently lost the ability to tolerate the proteins in most food grains. If you don't use it, you lose it.
Also, you may want to give antioxidants some thought. The metabolism can't function properly and your tissues can't regenerate without substantial amounts of polyphenols, flavonols, glutathione (or its precursor alpha lipoic acid), and vitamin C. If you eat grass fed animals, then you're probably getting enough CLA, that's a great metabolism booster. Plants do have some necessary micro-nutrients that are important for a balanced body, so it's important to at least include some isolated nutrients.
You mean very low density lipo-proteins (VLDL)? Those only get created when you each certain sugars. They stick to the artery wall like all low density lipo-proteins to be picked and transported by a high density lipo-protein. When the free radicals come in contact with a VLDL it is pushed into the wall and this can build up and cause atherosclerosis or arteriosclerosis. It is the packaging that the cholesterol is in (the lipo-protein) that makes all the difference. Otherwise, high cholesterol is actually healthier which goes against the popular beliefs of today. You have to be careful when you read scholarly articles because they may contain bias in the form of assuming that certain things are inherently bad like when they adjust for BMI and all that, they are probably messing up the entire experiment. There are also many experiments that put saturated fats and trans fats in the same category.
You would be surprised how many nutrients meat itself actually contains when prepared properly.
