I'm putting this in a thread of its own despite it cropping up, or being referenced, in various other threads on this site over the last several years.

Reason being I think the theory and practice Dave outlines to reduce cholesterol test numbers is a hammer blow to the conventional lipid theory of nutrition and cardiovascular disease.
Dave has his own site at https://cholesterolcode.com/ , but the gist of his theories can be got from the following vid,

I have now done my own N=1 on this. After a chol test in Feb 2019 I was firmly in the Lean Mass Hyper Responders (LMHR) club.
I then followed Dave's protocol of three days of excess calories followed by 12 hour fast and blood test. (I managed to find a chol test that doesn't report to anyone except me.)

Numbers as follows:
Date: 13/02/219 02/05/2019
Total Chol 6.73 5.89
HDL 1.70 1.82
LDL 4.79 3.70
TG 0.53 0.83

That comes to a 22% fall in LDL, by glugging down 4.5k calories plus of mostly double cream & bratwurst for three days.
I think I can tune this up a bit more if I find the right calorie numbers and carb mix.
However I think I've enough ammunition as is to give my doc pause for reflection.
