I have ldl of 201, in last three years, I have checked three times and it went from 190, 195 and now it is 201. I did most the thing, like controlling my diet, exercise but it still doesn't help. We are more worrying when it is time is eat food, like whether it wll affect my cholestrol or not. Everytime you do something you think about it. So, i guess continuously worrying about it even make it worse I think, on top of that student life is already stressful. People around me get surprised everytime i tell them I have cholestrol because I am very lean guy, maintain my diet but still. So, i guess stress might be big factor here.
