The latest post from Dr.William Davis' blog:
If small LDL is purely driven by excess carbohydrates, then adding saturated fat will reduce small LDL and increase large LDL.
If, on the other hand, your small LDL is genetically programmed, then saturated fat will increase small LDL. In other words, saturated fat tends to increase the dominant or genetically-determined form of LDL. If your dominant genetically-determined form is small, then saturated fat increases small LDL particles.</blockquote>
There are not enough details in this post but I thought I'll share it anyway.
