The reason I selected an hour after eating for postprandial measurements is that I had a Glucose Tolerance Test in 2008 and my blood glucose peaked 70 minutes after eating. All measurements were made with a pair of Accucheck Aviva glucometers and a Bayer Contour USB glucometer.
What does the science say? Jenny Ruhl has guidance on this at her excellent web site Blood Sugar 101.
My personal take on blood glucose targets and the selection of food to eat: my #1 goal is to never have to be on insulin. As a practical matter, I look at the results of the food tests in this web site and will, in the future, eat only those that have a minimal effect on my blood glucose. The New Atkins for a New You recommends that those trying to lose weight limit net carbs (total carbs minus fiber) to 20g during induction, then gradually add carbs in 5g increments as long as weight loss is not halted or other problems do not arise. Got a Request?I’m a very busy guy with the site, but if you have a special request for an item that should be tested, let me know. Glucose tolerance tests help to diagnose type 2 diabetes or impaired glucose tolerance - a condition that may lead to diabetes.
Glucose tolerance test – wikipedia, the free encyclopedia, The glucose tolerance test is a medical test in which glucose is given and blood samples taken afterward to determine how quickly it is cleared from the blood. Glucose tolerance test: learn what the results mean, Glucose tolerance test, was a routine oral glucose tolerance test ordered to diagnose type 2 diabetes, and gestational diabetes.
Glucose tolerance test for gestational and type 2 diabetes, Learn more from webmd about the oral glucose tolerance test, which is used to diagnose prediabetes, diabetes, and gestational diabetes.. Glucose screening and tolerance tests during pregnancy, A glucose screening test is a routine test during pregnancy that checks a pregnant woman’s blood glucose (sugar) level.

Evidence on the mode of action of metformin shows that it improves insulin sensitivity by increasing insulin receptor tyrosine kinase activity and enhancing glycogen synthesis in hepatocytes, and by increasing recruitment and transport of GLUT4 transporters to the plasma membrane in adipose tissue.
In addition to its effects on hepatic glucose and lipid homeostasis and adipose tissue lipid homeostasis, metformin exerts effects in the pancreas, vascular endothelial cells, and in cancer cells.
I’ve read in dozens of articles across the internet that reactive hypoglycemia is one of the first signs of diabetes.
In other words, if you have true reactive hypoglycemia (with symptoms appearing at 2-3 hours), the statistics say you are more likely to have a lower risk of diabetes. In order to illustrate why it isn’t easy to give a diagnosis for any particular disease, here is a graph of two patients who have just had a Glucose Tolerance Test (GTT).
Blood glucose levels alone tell you practically nothing about your possible prediabetic status! It’s very interesting because it explains how doctors and diabetic associations have it all wrong about diabetes risk. There are economical interests as to why the Diabetic Association don’t change their criteria for diabetes diagnosis and risk.
Considering this data it seems that many people with Reactive Hypoglycemia are indeed at risk for diabetes, because they have an impaired glucose tolerance. If you are just discovering your RH – please understand that it takes time for the carbo-cravings to subside.


I have not found a reason to avoid meat, but do best when I also include a sizable amount of vegetables. Please use newer version of your browser or visit Internet Explorer 6 countdown page for more information. This is because of changes over the day in how insulin resistant by body is and in the amount of insulin I produce, lingering effects of previous meals, glucometer inaccuracies, and other factors. It usually takes me about five minutes to eat, though I drank 75g of dextrose, the stimulus for my GTT, in under a minute.
Both measurements for each test (one before and one after eating) were made with the same meter. I am very skeptical of these targets, which do not appear to fully consider the consequences of blood glucose levels this high or how lower targets can be reached with a very low carb diet.
I am strongly motivated to avoid the need to inject myself with a drug that has to be carefully calibrated for the food I eat and the time I eat it. The table below shows colors associated with various average blood glucose increases measured an hour after eating. Richard Bernstein recommends that diabetics eat no more than 6 grams at breakfast, 12g at lunch and 12g at dinner for a total of no more than 30g per day. Eric Westman has had clinical success with diabetes patients at Duke University with a diet of just 20g net carbs per day.
Another exenatide-related drug is Bydureon® which is a once-a-week injectable form of exenatide. A more recent addition to the GLP-1 receptor agonist family of diabetes drugs is Trulicity® (dulaglutide) manufactured by Eli Lilly and Co.
Additionally, it has been shown that metformin affects mitochondrial activities dependent upon the model system studied. The latter effects of metformin were recognized in epidemiological studies of diabetic patients taking metformin versus those who were taking another anti-hyperglycemia drug. As a mathematician who teaches statistics classes at the college level, I have a pretty good idea. The patient with the red line is overweight (with most of her fat around the hips and thighs). A Hyperglucidic Breakfast Test is the only test that will be able to tell you if you have a high sensitivity to insulin (and therefore a lower statistical risk of diabetes) or a low sensitivity to insulin (and an increased statistical risk for diabetes). It seems that a high fasting blood glucose is not even necessary to be diabetic and that it is the worse predictor of diabetes. Reactive Hypoglycemia when connected with diabetes can be understood as resistant phase 1 insulin but excessive phase 2 insulin, whereas diabetes is resistant phase 1 insulin but unadequate phase 2 insulin. Sitting on the couch, eating that litre of Oreo Cookie ice cream (yes, I remember the carbo-munchies!) will lead you to diabetes just as fast as the non-RH crowd. I do better with rice, but even after 20 years I only consume a few tablespoonfuls with my meal. He recommends subtracting half of the fiber from the total carb count to estimate effective carbs. Metformin has a mild inhibitory effect on complex I of oxidative phosphorylation, has antioxidant properties, and activates both glucose-6-phosphate dehydrogenase, G6PDH and AMP-activated protein kinase, AMPK.
According to many prominent researchers (including Achim Starke, MD and Jean-Frederic Brun), it does not.


Giving a patient a diagnosis of reactive hypoglycemia (or prediabetes) involves looking at a few numbers, analyzing those numbers, and coming up with a diagnosis for the patient.
Another 20% said she had a 1% chance, and an incredible 60% got it wrong and said she had an 81 or 90 percent chance of having cancer! The red patient looks borderline, but the GTT cannot be used to accurately diagnose reactive hypoglycemia (to find out why, see my article on tests for reactive hypoglycemia). It seems that fasting blood glucose as low as 95 are already sign of impaired glucose metabolism. There are many diabetics in my family and none of them have diabetes markers: they are all thin, with no large waist and with low blood pressure. However there’s other literature that suggests such a low score would indicate further testing to find out the cause.
It took me a good 12-18 months for the cravings to fully subside, but eating a diet containing a balance of protein (I am not vegetarian), fat, and (after a couple of months) very complex carbohydrates worked for me. At some point, I may get a continuous blood glucose meter to measure my total glucose response, but this is definitely a limitation of my current tests. Also, some of these food products are rarely eaten with no other, the way I tested them; sandwich bread might be eaten with peanut butter and sugar-free pickles, rather than carb-free cheese,  and a salad.
The importance of AMPK in the actions of metformin stems from the role of AMPK in the regulation of both lipid and carbohydrate metabolism (see AMPK: Master Metabolic Regulator for more details). Unfortunately, physicians frequently misread health statistics, and do not know the probability that someone has a particular disease given the results from a screening test. Additionally, the red patient has excess body fat around her hips, which actually protects from diabetes! It seems that a reading above 145 at any moment in the glucose tolerance test is the best predictor of diabetes. My understanding was that RH+weight gain put more of a strain on the pancreas, resulting in a higher chance of diabetes. I do a lot of tests of each product and compute the average and standard deviation of the results. In adipose tissue, metformin inhibits lipolysis while enhancing re-esterification of fatty acids.
That’s according to a report by the journal Psychological Science in the Public Interest published in US News. The activation of AMPK by metformin is likely related to the inhibitory effects of the drug on complex I of oxidative phosphorylation. This would lead to a reduction in ATP production and, therefore, an increase in the level of AMP and as a result activation of AMPK. In fact, since the cells of the gut will see the highest doses of metformin they will experience the greatest level of inhibited complex I which may explain the gastrointestinal side effects (nausea, diarrhea, anorexia) of the drug that limit its utility in many patients. Hormones are chemicals that are released into the bloodstream and work on various parts of the body.
A glucose tolerance test helps to distinguish between this normal pattern and the patterns seen in diabetes and impaired glucose tolerance.
