What is the relationship between BMI and blood cholesterol ?

Caution: Please don’t expect much scientific content in this post. I Hope, you can spare a minute to answer this hypothetical question. What will be the shape of the curve,  If you plot BMI in the X-axis and LDL/ total cholesterol in Y-axis from a thousand normal adult populations? It will be linear for sure. Maybe a little curvilinear. Its likely J shaped with age  I think it is U shaped No, it is Inverted U Sorry, I don’t know. No one knows. Answer: Though linear relation is the one we expect, all sorts of shapes are reported in various correlation studies, making the response 7 likely to be correct. Why BMI refuse to go along linearly with LDL (Cholesterol)? Only an ultra-fraction of total body fat is represented as cholesterol within the vascular system. It’s worthwhile to note, total body fat store is about 8-10 kg,  the amount of cholesterol in circulating blood is hardly 10 grams. It is presumed another 30 grams is present in cells. Body synthesise 1 gram /day.I don’t know whether I can make this statement. It may appear total body fat and cholesterol are almost unrelated things in spite of the dynamism of Intermediary metabolism exogenous and endogenous cholesterol levels are modulated to keep the intravascular cholesterol within an amazingly narrow range.  How justified are we to expect a good correlation between BMI and Cholesterol?  Apart from the presumed logic, there ...
