I read that, it only covers NAFLD unfortunately and not insulin resistance.

Following a low-carb diet makes one a little glucose intolerant, which is the reason that the instructions for a glucose tolerance test always include the admonition to eat plenty of carbs in the week before the test. Why? Because all the macronutrients–glucose, fat and protein–are broken down by enzymes during the metabolic process. And all the enzymes necessary for the metabolism of the various macronutrients are made on demand but not immediately. If you are on a high carbohydrate diet, then you will have plenty of enzymes on hand to deal with the carbohydrates you consume. If you switch to a low-carbohydrate diet, it takes a while to manufacture the enzymes in the quantities needed to deal with the extra fat and protein that your metabolic system hadn’t been exposed to. This deficiency of protein/fat metabolizing enzymes is the reason people starting a low-carb diet become so easily fatigued–they’ve got plenty of enzymes on hand to break down carbs, they just don’t have the carbs to metabolize. Once they produce the enzymes necessary to deal with the load of protein and fat, which takes a few days, they become low-carb adapted and no longer feel fatigued.
Once people become low-carb adapted–as I hope we all are–then the same thing happens if they go face down in the donuts. They don’t have the enzymes on board to deal with the sudden influx of glucose, and, as a consequence, their blood sugar spikes higher than it would on a person eating the same amount of carbohydrate who is already carb adapted.
Dr. Eades, In preparation for a 3 hr glucose tolerance test–150-200 gm of carbs- I can’t imagine that many grams! Can you please give me an example of what to eat in one day to equal that amount? Will a week of the high carb diet be adequate for the test? Thank you.
Hi Margie–
Follow the standard American diet and you’ll double that carb intake.
What to eat? I would probably eat a potato and some bread and maybe a bunch of rice. You want to eat starch so that you will get glucose. Don’t eat a bunch of stuff with sugar or HFCS because you’ll get a lot of fructose.
You need at least three days of the higher carb fare for the glucose tolerance test to be accurate. I usually have patients follow such a diet for a week just to be sure. But, I don’t usually do a glucose tolerance test, I do an insulin challenge instead, which is much more revealing.

One caveat here is that very low-carb diets will produce elevated fasting blood glucose levels. Why? Because low-carb diets induce insulin resistance.
But then I thought about it. WHY does blood glucose rise in response to a low carb diet? It truly is an interesting question. What does it say about low carb diets if they induce an almost diabetic effect on circulating glucose?
Thus my research began. This short abstract confirmed that it is normal for people on low carb diets to experience a rise in blood glucose levels.
