Ouch! Doesn't sound fun. But, no turning back now, as soon as the appropriate opportunity presents.

Have you LOST your mind, Salim??????????? I can't think of a worse idea, not to mention that you would not receive accurate results having been on very low carb for so long. You don't have the predisposed insulin for such an undertaking. Your body may This One Time react appropriately and give you a free pass, or you may go blind, or you may acquire a nice case of ketoacidosis. Ayyy... Mad scientist.

That said, would it be too much to ask for you to pick up some insulin on your way just in case your body decides it would rather visit the pearly gates sooner rather than later? Oh, goodness, me....

Just remember, you are sorely needed here.

What is the point of eating more carbs before hand? Does that not skew the results you are actually looking for?

The purpose of the glucose tolerance test and its results are to know how a body in a "normal" state handles glucose. If we are ketoadapted, we are not in a "normal" state for the purposes of this test, so Any results would be inconclusive. Salim would have to replenish his glycogen supplies in order to get anything close to accurate, then he would have to stabilize there for some time before taking the test. It's rather like taking a gluten tolerance test after having been off of gluten for an extended period of time. It can't be done.

Thats my point, his normal is keto adapted. I would expect a lower BG number for the spare room in glycogen storage.

Sounds like telling a nonalcoholic beverage drinker to take a couple of shots of whiskey before drinking a beer to see what breathalyzer results would be. Maybe a bad example, but first thing to come to my mind this early.

Agreed. Theoretically, I would expect for it to be up to 200 points lower, depending on his system, unless he has a carb week for accurate determination. That said, we don't know what his normal is, which I'm guessing is the purpose of this test. That said, his system may decide to just go through the roof. Either way, the data would be skewed.

I maybe wrong as I have no former medical training but logic tell me this should be a pretty harmless test. Glucose is a very common substance everyone's body has had in fairly large amounts during their lifetime. Your body produces it, your brain needs it, it's food for your muscles. You seem to be in pretty good health, no meds, no eratic wide BG swings. I don't know why you wouldn't be fine.

If you are in doubt or apprehensive, maybe try a 25 G or 37.5 G test first and look at the results. If all is good, days or a week later do the full 75 G test. I don't see how the latter would skew your final results. Good luck whatever your choice.

Because he's not someone with a normally functioning pancreas. This is the concern that they're trying to convey. Being a T2 diabetic, his pancreas can't handle normal loads of carbs and here, we're talking about massive loads of carbs.

Thanks for the clarification.

I was under the impression that if you were a type 2 and either had too little insulin or was insulin resistant it could be from a diet too high in carbs. Once the carbs were limited and fats increased for the main fuel supply BG would stabilize.

My thoughts were if BG was within range for some time the body may loose its insulin resistance or insulin could handle a one shot high dose of glucose.

I guess we do not know these answers, hence the need for a test?

I wouldn't really call it a massive amount, for what we normally eat. 75 grams would be 2 to 3 times our daily intake, maybe 5 times what we would eat in at one meal. We are talking the equivalent carbs of a snickers bar and a coke.

Would measuring insulin be more meaningful than glucose? Or watching blood ketones drop?
