Why is my fasting glucose so dang high when I eat LC and low sugar?

Answered on August 19, 2014
Created June 05, 2012 at 3:21 AM

Between May 2011 and May 2012 I started eating high (healthy) fat and continued with my low carb., very low sugar and high protein diet. I got yearly labs done and I improved significantly in all areas of Cardiovascular risk. Total cholesterol has gone down since eating higher saturated fat!! Love that. All measures are in the optimal range in this area. However my fasting Glucose and Insulin are both too high (98 and 9.00)
My ND kept repeating that its from Carbs and sugar... sigh. Its not. I asked her to think about it more because in this case, that is not the answer.
Unfortunately my Hgb A1C was not tested this time but it was 5.70 (high according to my ND) when tested a year ago. Any thoughts are appreciated. Thanks

Thanks Marc. I will check this out. I read that its not so much, too much protein but too little sodium. My sodium was low. Thanks. I'll read it.

@corwler pre-diabetes is characterized by high blood sugar even in the present of high insulin (the get rid of blood sugar hormone) so yeah, it may.

lol. Yeah American Association of Anything (health or diet related) is something I do not trust! I am most def. getting retested for all this and soon. As of last night, I am eating slightly lower protein especially at dinner & eating a bit more carbs. Its unfortunate that my A1c as not part of this recent test. It was 5.70 a year ago and oddly, at that time my fasting insulin and blood sugar were way better (83 & 4.0). Thanks a lot

At the very least, it suggests pre-diabetes. A1c>5.6% and fasting glucose>90 can be problematic. However, these should be taken with a grain of salt, as the numbers are put forth by the American Diabetic Association and the American Heart Association.

Thank you Amy. I think this time, stress was not a factor. Really think its my high protein, fat and low carb diet. I will get a monitor. Thank you

Robin what I find interesting is that my fasting blood glucose and insulin were both better (lower) when I at more carbs. I think I am eating too low carb.

I definitely found this. I keep my protein food servings to 5oz at breakfast, 6 at lunch, and only 4 at dinner now.

I would agree. A reading of 98 would make me concerned enough to check my postprandial levels -- if they were fine, I wouldn't worry about the 98.

How much protein are you eating? Some people find this can be caused br overeating protein at dinner.

@Not a Doctor - I appreciate the link and will read it. She did not bring up pre-diabetes and there has never been any indication that this is an issue for me. Why do you ask? I mean I don't think those numbers suggest it, do they. According to her the insulin is in the Optimal range (8-15) however Mercola says it should be no higher than 5, fasting. hmmm?

I assume your ND ruled out diabetes or pre-diabetes?

people who eat low carb have a high serum glucose level than people who eat moderate moment amounts of carbs. http://perfecthealthdiet.com/2011/11/safe-starches-symposium-dr-ron-rosedale/

Thanks. I guess I need to learn about insulin resistance. If I am, I sure am not aware that I am! Do my values suggest i.r. ?

98 for fasting glucose is not really that high, IMO. Also you probably need to do more tests, that is have more samples to work with. If you have a glucose meter you can test yourself every AM for a few days and see what your average really is.

However, as i said, 98 is not all that high. IMO you are not doing any internal organ damage at that level. With your meter, you might want to check your postprandial readings, that is say one hour and two hours after eating.

If you stay LC and paleo, you probably will not do further harm to your pancreas beta cells.

Peter at Hyperlipid has something interesting to say about this here. Essentially, your muscles and other tissues are becoming insulin resistant, since they can run on fat, in order to save glucose for the brain which needs it more.

Good advice here so far -- excessive protein can raise blood glucose (and therefore insulin), but how much is "excessive" is an individual thing. I agree that a fasting BG of 98 isn't super high, but it could stand to be lower. Is the 98 you cited from only one test? If you're concerned, get yourself a meter (can be bought at most drug stores these days) and test on a regular basis. If it was just the one day's result, it could just be an aberration.

How stressed out do you normally feel? High stress levels - especially for long periods of time - can elevate blood glucose even if you're following a lower-carb plan. (Due to the effects of cortisol.)

It is probably too much protein. See:

Your liver releases glucose while preparing your body to wake up and begin the day. My morning glucose reading is always higher than it was before I went to bed. If you are insulin resistant, your cells won't take up the glucose any better than if you were to eat a doughnut.
