A lipid subfraction analysis undertaken in the 262 study participants found that patients on the LC/KD had lower levels of sdLDL particles (type IIIb), increased HDL levels and unchanged levels in the atherogenic Apolipoprotein B (ApoB) and LDL levels, supporting the evidence that longer term LC diets may not adversely affect heart disease risk (49). Here, APOB is linked to heart disorder.
