I dunno, but it does.
My cholesterol was at it's very best (205) when I was eating a high-fat, red meat at every meal, lots of booze, low fiber diet, and riding like a madwoman. (Diet heavily influenced by my German sweetie at the time.)
Supposedly alchohol lowers cholesterol (I had one doc tell me to drink one beer/glass of wine/shot of whiskey a day) but I think it was the exercise that really did it for me.
