Because of homeostasis: dissolved substances like fats in the bloodstream are regulated within bands, and beyond certain limits the amount ingested doesn't translate to more: it's excreted or winds up elsewhere. Your metabolism may cause states worse than other people, sure. But that pound of butter you ingested isn't directly causing rises in the bloodstream to infinity. It's long-term accumulated burden and excess over time.

Cholesterol levels don't track intake directly. Lowering cholesterol and fat in diet needs to be done in consultation with somebody who understands your metabolism. Some vitamins are fat soluble. Some fat is beneficial.

Homeostasis is amazing.

While I always knew that sugars where the main culprit for body fat thanks to a highschool biology class, I have never understood why fat is less of a problem so thank you. Could you link me with sources or search keyword in order to know more of what the body is doing with excess fat ?

I tried "what does the body do with excess fat" and I think it covers it. For sure, you get higher triglycerides floating around in the bloodstream, and the liver is under stress. at the extreme end, its Steatorrhea which is .. unpleasant (olestra goes to the same place)

The lymphatic system is also involved.

So it's not entirely "eat as much fat as you like" by any stretch. It's more that over time, the body tends back to a baseline model. Continual high levels of fat which cause surplus in the bloodstream are heading to arterial blockage and isn't good, but the relationship of fat ingested to fats in the blood is a more complex path. "it depends"

I'm not a bio scientist or a med. Happy to be corrected.
