This is anecdotal, so don't take it for too much.

The older sister of a coworker had high cholesteral problems. She had always been a light eater and was not overweight. She kept cutting back on all sorts of fats to the point she was effectively a vegetarian. Her cholesteral still kept going up despite this.

She started eating high-cholesteral foods like eggs and steak every day. Her cholesteral went down. He doctor yelled at her.

The way it has been explained to me is that cholesteral comes from two places: the food you eat and what your body produces. For some people, if they don't get enough from their food, they start to produce way too much of it.
