Interesting video. This fellow tracked the effect of dietary fat on various blood lipid numbers while on a ketogenic diet. He found the more fat he'd eaten the last three days, the lower his cholesterol and ldl were. Ldl particles had a lag, reflecting the last five days consumption, but again--the higher the fat, the lower the particle count. He shows the effect in subject after subject after subject.
