Only the OGTT, which I refuse. My last two tests were done without changing my <50 grams of carbs per day. – MathGirl72 Sep 17 at 16:31

i refuse to take the OGTT too. It sounds like a brutal test. – holly Sep 17 at 16:35

It is horrible. The last time I drank their glucose concoction I threw it up. The next time, they had me drink a very under-diluted Country Time lemonade drink that was disgustingly sweet. This was all pre-Paleo. I will never subject myself to that again. – MathGirl72 Sep 17 at 16:44

IMO, you should eat the same way before a blood test (except that many you have to fast for 12 hours) as you normally do (including the OGTT if you want to take that test). There's no need to find ways to "fool" the test. You want to know what your real results are so you can be better informed, otherwise why even take the test in the first place?

The important thing is to have a doctor who will help you interpret the results as part of your general health. Not a prescriptive (you had X score so I am going to give you Y medicine).

okay sorry, but i normally eat LC, would you consider this "fooling" the test? or is eating like a normal person with more carbs "fooling" the test? thanks – holly Sep 17 at 17:15

Carbing up with 150 g of carbs in the few weeks prior to an OGTT is not "fooling" the test. If you are normally low-carb, suddenly ingesting the massive amount of glucose in those concoctions can cause results that aren't indicative of your actual ability to process glucose. – MathGirl72 Sep 17 at 17:26

if you normally eat LC, continue to eat LC. The test results will be whatever they are. It is more important to know how to interpret the results. Yes, you won't have the carbohydrate enzymes circulating throughout your body. So your doctor should augment their interpretation of the results accordingly. – CD Sep 17 at 17:29

@MathGirl72 -- No, it shows your current ability to process glucose. Which is important to know. The real question is why take the OGTT in the first place? If you are doing it for a specific purpose that might change my over-arching philosophy. I see people changing their diets in the 2-3 weeks leading up to a cholesterol test so they can get better numbers.... IMO that is counter productive. You should know what your real numbers are, not what you can get to if you made changes to your diet – CD Sep 17 at 17:32

If it is to determine Gestational Diabetes, I've been advised by multiple midwives to make sure I am eating at least 100g of carbohydrate per day in the week leading up to it.

The parameters that your healthcare provider has been given to interpret the test are based on someone eating the typical carbohydrate based diet. Being in ketosis will screw with the results.

Going in there VLC, you are in a state of functional insulin resistance, and the test can't differentiate between that and pathological insulin resistance and glucose intolerance.

Eating a solid meal of mixed macros is important the night before the test as well. I know someone who bombed the test (but it turned out did not have GD) because she went out for hot chocolate the night before the fast and forgot to have a big dinner.

been eating low carb, do i need to “carb up” for a fasting insulin/bs test or
