Hi
@Wilber123. The LCHF lifestyle will most likely have an impact on cholesterol, it can be confusing, as for decades we have had it drummed into us that fat is bad. Cholestorol is made of LDL, HDL and Triglycerides. The statins and low fat diets work on lowering LDL whereas LCHF works on HDL, Triglycerides and for around two thirds improves LDL.
The LDL number is not broken down to see if these are large or small particles which can be the important aspect. Large is what is desired. Considering cholesterol is in every cell in our body, I am in the camp that we should tread carefully, as this is vital for cognition, reproduction and many more functions.
The LCHF protagonists believe in general that the Triglyceride to HDL ratio is more important to heart health than LDL scores (perhaps baring familial hypercholesterolaemia affected persons (these persons have a family history of extremely high LDL)). For absolute definitive answers as to heart health risk a CAC test can be taken which is the gold standard, as it sees the disease rather than best guess (which the other protocols do).
If you are a reader than you can get full answers to this conundrum in the brilliant work of Nina Teicholz's "The Big Fat Surprise" - this has driven a coach and horses through in my view the abysmal death promoting hypothesis which has driven "our" beliefs and food choices; women in particular react more negatively to lowering cholesterol than men. Ivor Cummins (The Fat Emporer) is also worth reviewing on YouTube - a brilliant engineer who has looked at this issue from a advanced problem solving angle, I think this is some of the best work out there. Zoe Harcombe has a compelling view also. Lastly Dave Fieldman (
http://cholesterolcode.com/) has made a mockery of cholesterol numbers by demonstrating how a set of tests can be manipulated in 3 days to for example gain a favourable insurance premium.
The other aspect to note is that if you loose weight then cholesterol numbers will be all over the place as the fat shows in the blood as well.
