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. Type 2 diabetes mellitus is characterized differently and is due to insulin resistance or reduced insulin sensitivity, combined with relatively reduced insulin secretion which in some cases becomes absolute. When glucose levels become depleted, glucagon and cortisol levels rise significantly to enhance gluconeogenesis.
Up-regulation (receptors) occurs with insulin after 4 weeks of exercise to increase its sensitivity (diabetic importance).

So, the C-Peptides follow roughly the same arc, and ratio of rise, as the insulin levels.  So, now I know.

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.
He recommends subtracting half of the fiber from the total carb count to estimate effective carbs. 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. I do a lot of tests of each product and compute the average and standard deviation of the results. 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.
