I had the same issue. I didn't get tested until I was on very low carb for well over a year and pretty close to goal. My LDL pretty much doubled. That happens to a very small percentage of people. I don't and won't take statins again so I have had to make some changes. I quit using coconut oil and bacon grease. Now I mostly use Olive oil and just a bit of butter for eggs. I still eat eggs, but not as much as I was. Cut back on beef and pork, eating more chicken and fish.

I will get retested in a couple of months and hope the changes I've made help.

I have read that what you eat doesn't affect your cholesterol...but that's not true for everyone, because some unlucky ones like me are affected by high fat eating.
