My name is Christine Marquette and I’m a registered
dietitian with the Austin Regional Clinic and I’m going to talk to you about how to
fast before a blood cholesterol test. Typically the only thing that the lab will ask you to
do is to make sure that you don’t have anything to eat or drink for twelve hours before they’re
going to do the blood draw for cholesterol. You can still drink water. Some labs will
allow you to also have plain black coffee or tea, but no other types of fluids. No fruit
juice, no sodas, nothing that has any calories to it. You won’t be aloud anything like Powerade
or any sports drinks. Absolutely no solid food for the twelve hours prior to your cholesterol
test. There isn’t a requirement as far as modifying your diet any time up to that. For
example: in the week before hand, you don’t have to change your diet in any kind of way,
typically it’s better if you don’t. It’s better if you follow your normal eating habits, that
way you get a more accurate indicator of how your cholesterol is doing. In some people,
cholesterol is very much affected by their diet, so for example, if they’re eating a
lot of saturated fats, whether that’s from things like bacon or fried chicken or a lot
of cheese, or those types of things, it will show up in their cholesterol test and their
cholesterol, their LDL cholesterol will be elevated. By the same token, if somebody modifies
their diet and starts eating a lot of high fiber foods and they normally don’t do that,
say for example, they know they have their cholesterol test coming up, so they really
start eating a lot of oatmeal and reducing any of their fried foods, eating a lot more
vegetables. A lot of times that will show up as well, and their cholesterol levels will
be lower. So, the best thing to do is follow your normal diet and then twelve hours before
you’re scheduled to have your blood drawn, you’re fasting, drinking only water. That
will give your doctor the best indicator of how your cholesterol truly is and then you
will know if you truly need to make any diet modifications or not. So, those are just a
few tips on how to fast for a blood cholesterol test.
