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.
