a few ideas for you. The fat content in kefir most likely isn't any higher than whole milk,, 4-6 percent. More than likely it's the breakdown of lactose that aids in your digestion, and possible some breakdown on casein, the milk protein.
Coconut milk ( the liquid inside the coconut) also has minimal fat, if any. Coconut cream (the liquid from pressed coconut meat) naturally has lots of fat, but almost identical to the fat found in coconut oil, which for most is readily digestible. Although some here have quite a problem with it. I have always believed that the oil they've bought may have said it was low temp virgin oil, but I know that in the market place of Coconut oil, a lot goes on...
The peoples of the north ferment quite a bit of fatty foods with various techniques. And there has been talk here about it. I have suggested that for those peoples, staying alive is paramount and the ingestion of oxidized fat would be secondary. And for some, like whiskey or other fermented foods, one can develop a taste for it, where initially the body most often is trying to have you reject it. I feel that way about oxidized fats.
IF one could ferment the fat without oxidizing it,, Wonderful! I don't know how you'd do it. I know for myself, I simply get more energy when I eat fresh fat from the butcher than fat that has been in my fridge for a few to several weeks. The same holds true when eating fat that's been frozen vs. fresh.
It's very easy to overeat fat when combined with meat, because meat simply tastes better ( to me ) with fat. And the combination can lead to overeating too much of both. One way to see how much fat you can eat and digest well at one sitting is to simply eat fat plain. In some time the taste and desire to eat more will change. That will be an indication as to how much in general you can eat. Fro me that amounts changes often.
I also go in and out of the practice of grinding my fat and placing it in a bowl and placing that bowl in a large pot of water at body temp for about 20-30 minutes. Most of it will melt and the rest will be very soft. Again, mixed with meat, it is very easy to too much of both. But for me I've found to derive most of my energy and thus calories from fat, I do better if I eat it more often through out the day rather than just one or two meals. And hence the same with protein. I try to eat so that I never feel full and the need to rest. And of course some here will do better eating just one meal a day. But experimentation is the way to find out what works for you. I also wait till I'm hungry, have no set times to eat, but again, I eat less than I would if I didn't tell myself to stop ( so easy to keep shoveling it in, thinking more is better). I really like the idea of eating just what the body needs. We often here about the anti aging benefits of fasting, or severely reducing caloric intake.
Much of the benefit Could simply come from reducing the constant overload of eating more than our body needs at one meal. Remember the body can't store proteins, and excess fats I believe also pose a disposal burden on the body. My two cents worth.
