The best test predictor of atherosclerosis risk is your small LDL particle count. That's because atherosclerosis is really caused by the collision of Apolipoprotein B (Apo B) molecules with blood vessel walls and the cascade of inflammatory responses thereafter. Small LDL particles are much more likely to collide with the walls and get stuck, while big LDL particles may actually be protective against atherosclerosis. In short, you shouldn't be worried about big, fluffy LDL.

Overall cholesterol levels mean very little. LDL concentration doesn't tell you much about LDL particle count. High triglycerides can also mask high Apo B counts, but your trigs weren't high enough for that to be true.

I'm concerned about two things: your Total/HDL ratio is increasing and your trigs are increasing. The change is small, but if the trend continues, you may want to take some steps to change it.

You still need to tell us more about your dietary habits along this timeline.

First what statin were you on? Was it a strong one like Crestor or Lipitor? Dosage? Or a less toxic one like Pravastatin? If you go off a strong statin, everything else being equal, your LDL will increase. Ergo, your TC will increase. More often, your TG would increase, too.

Assuming you made no dietary change before and after, the reasonable explanation is that you're probably ApoE4. About 25% of the population is either hetero/homozygously E4. You're genetically predisposed to higher LDL and TC when eating saturated fat like dairy, eggs, beef. Assuming: You're not undergoing any weight loss. You have no thyroid issues nor pronounced micronutrient deficiency.

That increase in LDL-P from 1500 to 22-2800 is an issue. That's pretty significant and TC of around 300 is getting up there. Perhaps not FH but probably E4-induced. I'd lay off saturated fat from dairy, eggs, try eating lean beef an fish, poultry. Then retest. To confirm, you can sign up with 23andme and get your rs7412 & rs429358 genes figured out.

Why is this happening? Polymorphism. That is, SNP: Single Nucleotide Polymorphism. People react differently to diets. There is no one size fits all diet. High fat Paleo may not be ideal for you. If you wanna lay off statin, might try high carb, safe starch Paleo. But I'd focus on getting your LDL=P down below 1200.

Why did the small LDL-P increase between 2/14/12 and 5/21/12?? Did you change anything in your diet?

What is your diet like now?
