cholesterol /cho·les·ter·ol/ (kah-les´ter-ol) a eukaryotic sterol that in higher animals is the precursor of bile acids and steroid hormones and a key constituent of cell membranes. Most is synthesized by the liver and other tissues, but some is absorbed from dietary sources, with each kind transported in the plasma by specific lipoproteins. It can accumulate or deposit abnormally, as in some gallstones and in atheromas. Preparations are used as emulsfiers in pharmaceuticals.

Q. Does wight loss lowers cholesterol? I'm 5'5, 175 lbs, 40 years-old man. After my doctor found that I have high LDL cholesterol, I was advised to try to lower my weight in order to reduce my cholesterol levels. Otherwise I'll have to start taking medications. Can it really do something? As far as I know, cholesterol level are pretty much a genetic thing, and one can be very thin but still have high cholesterol levels.
A. Your doctor isn't totally wrong. Cholesterol levels, as many other things are influenced both by genetic and non-genetic (e.g. diet, physical exercise) factors. Changing your life style (mainly changing your diet and starting regular daily exercise) can lower your cholesterol level, and if it's not too high to save you from the need to take meds, at least currently.
Your genetics does influence your cholesterol, but it's not a pre-determined thing.
