metabolic endotoxemia 
= the 
lipopolysaccharides (aka LPS or else Endotoxins) found in the bacteria cell wall, that (gut) bacteria generate, fall in blood stream (due leaky gut).
sdLDL = doing the atherosclerosis. sdLDL easily oxidized. Going into 
endothelium of blood vessels and made the atherosclerosis.
the lipopolysaccharides bind to LDL and make it 
sdLDL (here is possible your LDL count to be OK, but sdLDL not)
sdLDL associated with 
fatty liver which associated with 
gut problems.
Stress increasing the 
lipopolysaccharides to your bloodstream ( description above^ ) even when you dont have gut problems, for moment/hours can make it leaky gut. Here is how @ the brain communicates via 
vagal nerve with the gut and orders to release 
cortisol hormone and this releases also peptides from 
mastcells then the gut lining destroyed (inflammation & permeability).
Eating junk food also helps 
lipopolysaccharides penetrate the gut.
Bad bacteria 
lipopolysaccharides penetrate the gut.
70% of immune system is in the gut, T cells and B cells exist there, LPS when passing to bloodstream stimulate those cells and resulting to produce inflammatory cytokines molecules (inflammation), cause immune problem as well.
Inflammatory cytokines molecules travel to the brain, passing the BBB and causes 
inflammation in the brain (mental fog / depression). Depression associated with atherosclerosis.
LSP goes to the 
liver and cause 
fatty liver [
2] and the 
muscles made 
insulin resistant. You get a 
metabolic syndrome,
- blood sugar goes up
- triglycerides go up
- HDL goes down
All those markers are of 
atherosclerosis. The 
metabolic syndrome causes 
inflammatory fat, the LPS going into the 
healthy fat tissues, activates again the immune system, that's why we found inflammatory cells in the fat (obesity person : almost the 50% of the fat are inflammatory molecules).

			sdLDL to be a better predictor of cardiovascular (CV) risk than 
LDL-C, even in patients with low cholesterol 
(LDL-C < 100mg/dL).
Similarly, the 
JUPITER trial linked 
sdLDL to CV deaths . . . even in patients with very low 
LDL-C.

GPT :
LDL-C (Low-Density Lipoprotein Cholesterol) : Refers to the total cholesterol content within all LDL particles in the bloodstream. It is a common measure used in lipid panels to assess cardiovascular risk. Includes 
all sizes of LDL particles, both large and small, and is typically measured in milligrams per deciliter (mg/dL).
sdLDL (Small Dense LDL) : Refers to a 
subclass of LDL particles that are 
smaller and denser than typical LDL particles. These particles are often considered more 
atherogenic (more likely to promote the formation of fatty plaques in arteries) than larger, less dense LDL particles. Elevated levels of 
sdLDL are associated with a higher risk of cardiovascular events, 
even when total LDL-C levels are within normal ranges.
