Medical Forum / Diseases and Disorders / Diabetes / November 2008Atkins
Dr. Atkins writes that you should consume at least 150 grams per day of carbs for at least four days before having a GTT otherwise the results will not be accurate. If you are on his diet, you must go off for a few days before the test. Otherwise you will test diabetic. He gives no explanation. Does anyone know why you would test diabetic with the GTT on a very low carb diet?

The pathways of efficeint fat metabolism and insulin sensitivity are to an extent mutually incompatible. This phenomena has been well documented in short term fasting when fat metabolism is really amped up. Immedialtey after the fast insulin resistance is increased and the GTT is degraded. BUT, this is a temporary effect and a few days after the fast insulin resistance can be decreased over the prefast levels as fat metabolism is decreased I'll be happy to provide references if requested. BTW Delores I'm more in agreement with your dietary views than not. I've been very impressed with your results on a higher carb diet. Regards Randy > Dr. Atkins writes that you should consume at least 150 grams per day > of carbs for at least four days before having a GTT otherwise the [quoted text clipped - 4 lines] > > Dolores The explanation involves the pancreas' provision/anticipation of insulin needs and pattern of secretion "programmed" by previous meals. If meals just previous to the GTT are very low carb, there will not be a sudden, large bolus of secretion, but a slower, steadier, healthier rate of secretion of the sort provoked by a low carb, higher fat and protein meal. Loading with carbs for days allows for the large bolus on the test. Susan > x-no-archive: yes > [quoted text clipped - 16 lines] > > Susan Can you provide data for the above.

You refered to the citation which you cannot site, but its my responsibility to find it. That's nonsense!! Also I've looked into the issue and the only evidence based data I found was the temporary ieffect of reved up fat metabolism increasing insulin resistance not the explanattion that Susan reported. Ofcourse it may still be true and I'd be very interested in seeing it. Maybe someone that has the book can report the source.

That's nonsense!! Randy, if you haven't read this basic book, you really should! Nicky.

Does anyone know why you would test diabetic > with the GTT on a very low carb diet? Hmmm. I'm trying to think how it would work with me. If the diet is keeping my FBG _and_ my A1c low without introducing other problems, why would I be taking a GTT ?

Now that we have meters to test bg, why would anyone endure the torture of a GTT, other than for other, difficult to diagnose conditions, such as insulinoma? Susan |
