What kind of dairy? If you really want to give it a go, try to get grass-fed dairy if you can. If you can find raw milk in your locale, even better. (Yes, there is a slight risk of getting sick from it. You are at just as much risk of getting sick from pasteurized, though, and you can get sick from other raw foods as well.) If you're getting organic milk, check the label and see if it's ultrapasteurized. Most commercially available organic milk is. They might as well have cooked it, there's not much good in it left and the proteins and fats have probably been altered to a form that has your body going "WTF???" The Weston Price Foundation says there are huge differences between raw, pasteurized, and ultra-pasteurized and I've heard anecdotal accounts of people who get allergies or breakouts on the latter two but do fine on the raw.

As far as other fat sources, probably it will be better for you in the long run to get more beef fat in your diet rather than chicken or pork fat. I love me some chicken wings and bacon and I have cooked with lard, but both of them contain more PUFAs than I would like, especially the chicken.

Coconut oil is excellent too. Lots of medium-chain fatty acids. Even someone with a wonky or missing gallbladder can usually handle coconut oil with no problem.

What about olive oil, cocoa butter or red palm oil? Also, macadamia nut oil? And some people have good luck with ghee when they can't eat regular butter.

Chunks of beef fat in stews. Find a butcher where you can get it cheap and you'll save yourself the expense of buying fatty cuts of beef all the time. Save bacon fat and chicken drippings -- refrigerate the drippings and scrape the fat off the top for cooking, and reserve the gelatin to melt in stir-fries for flavor. Buy non-shelf-stable lard (the kind without all the additives) for cooking.

This is the reason I've kept massive amounts of butter and cream in my diet. I need to get a lot of calories, and no other fat is so palatable and versatile.

Other main fats are coconut oil and beef fat (and sometimes leftover bacon fat) for cooking, and olive oil for cold dishes. Need to get some lard.

The last of my acne is gone since I stopped with the Greek yogurt, and all but small amounts of raw cheese. But I suppose my skin could still be better...
