Actually, it can go any direction. Some people see it go up, and some see it go down. I think a lot of it depends on what fats you are eating.
I, for one, advocate regular consumption of tallow and coconut oil - and my HDL went from 50-something up to 94 once I started this. That naturally means my total is higher, but my tested LDL was only 134, up from something like 120, and my trigs were ridiculously lower. I DO NOT take fish oil, because I do not seek systemic inflammation, but I do eat fish. Polyunsaturated fats are heavily overrated, IMO.
I would eat this way for at least six months and retest. Get the direct LDL, not calculated. And do a VAP if you can, to get info on your particle size. CRP is also good, to see if you have any inflammation to worry about.
Steak, eggs, potatoes - fruits, nuts, berries and forage. Coconut milk and potent herbs and spices. Tea instead of coffee now and teeny amounts of kelp daily. Let's see how this does! Not really had dairy much, and gut seems better for it.
