1/ Still one of my favorite studies in relation to the #LipidEnergyModel. One might wonder what happens to animals who become fat adapted due to fasting for a long period.

Obvious example: Hibernation

#LDL #Cholesterol goes up... does #Atherosclerosis?

2/ They were comparing bears in captivity and the wild. And in both, lipid levels during hibernation are "considerably higher than what is normally found in humans"

3/ In spite of the high lipid levels alongside other risk factors, they found no signs of atherosclerosis in brown bears.

4/ They actually have some cross sections from autopsy, including LAD...

5/ To be sure, I'd want to add one more possibility to this list below...

... It's possible the scenario of higher ApoB-lipoproteins in the context of fatty acid trafficking is not itself pro-atherogenic. This seems to correlate with human populations that fast regularly as well
