Let's do a simple test - OGTT
OGTT (oral glucose tolerance test)
or a test of the body's reaction to 75 g of glucose.
Why this test? It is based on the findings of a study that divided people into five groups. It has been shown that fasting blood glucose, which is commonly used, has very little to do with metabolic health, thus indicating some other disease or being accidental. The test that evaluates the differences in glucose levels in a stress test is far more accurate. It would be even better to measure the level of insulin in the blood, but you will not measure it yourself at home.
You will need a regular glucometer and glucose or dextrose sugar, both from a pharmacy. We will measure blood sugar four times during one test, it is a good idea to set the test time in the morning so that you can repeat the test at the same time and be able to have a drink with MCT oil an hour before the test.
The self-test is performed by dissolving 75 g of glucose or dextrose in a glass of water. You really let it dissolve completely, no crystals should be seen. You measure your blood sugar at time 0 and then drink the prepared solution. After 30 minutes you measure the second value of blood sugar, then you measure after another half hour, ie one hour from time 0, then after another hour, ie two hours after time 0. So we have four values of blood sugar, at time 0, 1/2, 1 and 2 hours, let's denote them a, b, c, d. We substitute these values into the formula for calculating the area under the curve:
dAUC = ((b-a) + 1.5*(c-a) + (d-a))/2 mmol.hr/L
Now you can ases youself by the mark one to five like this:
And the next day you can test what a small drink will do with the test, eg morning coffee prepared by mixing two teaspoons of butter with two teaspoons of MCT oil (containing C8:0 and C10:0, without C12:0) topped with a cup of coffee (or tea) . Drink about an hour before the OGTT test.
Note 1: If you measure an "a" value, fasting blood glucose greater than 7 mmol/L, then do not drink the prepared glucose and consult your doctor.
Note 2: The value of "a" fasting blood glucose is often used in medicine, but its value practically varies greatly and is completely unsuitable for the actual assessment of the metabolic syndrome. OGTT is a much better indicator.
Note 3: Write down the dAUC values so that you can keep track of the history.
Note 4: It should be noted that there is also a relatively significant difference between marks 1 and 2. Even if you get only a small increase in your blood sugar in the test, a score of 2 may mean that you still have high insulin. This is not an ideal situation and it is prudent to continue to improve.
If you are on a low-carb or keto diet, won't you fail this test. I thought you had to eat a certain amount of carbs per day in the 3 days leading up to the test. (I don't remember the amount).
ReplyDeleteYes, it is recommended to take at least 150 g of carbohydrates three days before the test. If you don't eat carbohydrates, the enzyme pyruvate dehydrogenase is suppressed by burning fat, so it needs to be revived. There is no point in doing this test on a keto diet. if you don't want to eat carbs. If you want to eat carbs safely, you need to reduce your free fatty acids. This test will tell you if this reduction was successful.
