The medical field's view of cholesterol is dangerously old-fashioned. Most are still talking about good and bad cholesterol, based on the lipid hypothesis which was fabricated from thin air to satisfy political agendas. The very study performed by Dr Keys that he supposedly used to support his theory actually shows no evidence of what he claimed. In fact, there has never been a single study that supports that hypothesis. Statin drugs address a symptom, not the cause. If you want to control oxidized cholesterol deposits in your veins, the proper solution would be to lower the amount of carbohydrate you regularly consume.
Fasting doesn't affect cholesterol readings- the Dr. is right about that. It does affect triglycerides and things like that.
Here's something important to note- while everybody is on the "lower your cholesterol" bandwagon, a high cholesterol level has never been shown to be involved in heart disease, and lowering the cholesterol level in someone's blood test has never been shown to reduce the risk of a heart attack!

All of what we 'know' about cholesterol and heart disease is based on a flawed study, and a guess that dietary cholesterol is at fault and that bringing down our cholesterol levels fixes that. That is just simply wrong.
What does indicate risk of heart disease is inflammation (CRP), insulin resistance (your fasting blood sugar), and homocystein levels. Those are the blood tests you need.
My husband is going to be 60 in the next couple of months, and he was told he needed to reduce his cholesterol and his blood pressure was a little high. So we did a ton of reseach, and in early 2010 changed our diets to a low-carb lifestyle (sort of a modified paleo). Both of us are on 0 medications, and are not overweight, and currently the picture of health. I scored a "96 out of 100" at work for health insurance purposes- weight, BMI, body fat, blood sugar, and (yes) cholesterol since I work at a hospital.
here's the thing- I scored higher than people half my age but I flunked!
Because they sit you down with a nutritionist who asks "How many times a day do you eat complex grains/whole wheat?" (The correct answer is 5 or something). I said, "0"! "How often do you forgo meat and eat beans and rice per week, in other words, how many meatless meals do you eat per week?" Um, "0". And on it went.
Even nutritionists don't have the latest info on these things, and will tell you a low fat/high carb diet is the way to go. And this is why obesity rates are something like 1 out of 3 adults (and even children!) in America, and why people have diabetes at higher rates than ever before, and heart disease is still the #1 killer.
Sorry for the rant- but this is what makes me crazy. I worked in the health profession my whole life, and we are killing people with false information and making them sicker than ever before.
