Is my blood sugar spike due to my unintentional "low" carbing?

Answered on August 19, 2014
Created July 28, 2012 at 2:04 AM

After I came across Chris Kresser's article (here), I bought a glucometer and strips and checked out my BG according to his protocol. The first two days, everything was gravy. Fasting BG is around 79, and the highest I saw it hit was 116 1 hr after a meal of braised lamb and leftover rice with a snack of watermelon. Pulled pork with sweet potatoes and...ahem...a couple of craft beers? Same deal. Then it was back to baseline within the proper window.

I have been playing around with it for awhile, and then today ended up eating a hideous, regretful Waffle House (oh God, I know) meal - "syrup" (because it's HFCS...not maple), waffle, chocolate chips, hash browns, bacon, raisin bread...I don't know why I bothered to order unsweetened iced tea. Yea, and so I prostrate myself on the altar of good health, may I be forgiven!

I thought - well, since I haven't done Chris' third day test, might as well check it after this disaster. 1 hr postprand? In the 170s. Two hours later, and I'm still at 166. I have checked it several different times to see if I was making an error somehow.

I thought, well, this happens to people who eat low-carb diets, right? Physiological insulin resistance? But I don't know that I'm a low-carber. We eat white rice, sweet potatoes, white potatoes, root veg, etc. with pretty much every dinner. I am a fruit-devouring monster, so a day with a handful of berries, cherries, a plum, and a bowl of melon isn't uncommon when it's in-season. We make homemade mead and hard cider, and occasionally crack a gluten-free beer, so there's that, too.

I am just trying to figure out why my blood glucose was so high. Is this low enough carb intake to produce physiological insulin resistance? Was it because it was a meal that was just insanely carby-sugary-unnatural?

Here is what I think my carb intake would be like on my highest days (such as the days I mentioned above where BG was normal), excluding incidental carbs such as those from green veg:

1 c. white rice - 45 g
1 plum - 8 g
1 c. melon - 16 g
8 cherries - 8 g
1/4 c. blackberries - ~4 g
The sweetest homebrewed hard cider we've made (estimated) - 20 g

=101 g...my intake is probably around 1800-2100 kcals/day, so that's 19-22% of total energy. Fat probably rolls in close to 60%, which leaves 20% for protein.

What say you? Was it because I probably nommed the same amount of carbs in one sitting as I usually eat during the entire day? Should I be worried? Suggested further n=1 experiments (no more junk food; I felt like a beached whale after that meal!)?

The last time I was pregnant, I warned both my OB/Gyn's nurse and the lab technician that I would, without a doubt, throw up if they insisted I drink it. I was right, I did and I was PISSED.

Jeff, I felt like crap afterward. I have not eaten so poorly in a long time - I couldn't believe that I had eaten that way so much more often in the past. Robb Wolf mentioned hormetic stressors in his most recent podcast (142, I think), and my n=1 confirms this...eating paleo has made me much less resistant to garbage eating. Thank for the comment. Best wishes for hopping back onto the paleo wagon. :-)

I'm a Type 1 diabetic so I've been tracking my BG for years. When I eat at least 100 g of carbohydrate per day, 1 unit of Humalog insulin will be sufficient to cover 20-25 g of carbohydrate. If I restrict my carb intake to 50 g/day 1 unit of Humalog will cover only about 15 g of carbs. Eating more than 100 g/day of carbs did not result in any improvement in insulin sensitivity.

I had almost the same meal yesterday at Awful House. Only difference was I asked for the sugar free syrup. (I know, why bother). I haven't eaten at WH in years and was in a pretty crazy place emotionally. Just letting you know you aren't the only one Blossom1. BTW, my BS did about the same thing. I'm diabetic so I didn't expect anything other than what happened.

NBS, interesting - were you measuring blood glucose, or did you have an issue with an OGTT to have noted the developing IR? It must come in degrees, since rice+watermelon and sweet potatoes+beer didn't affect my blood glucose negatively at all (probably an intake of ~75g at a sitting, plus a significant amount of fat), but the waffle house bonanza did (which is likely around 125g at once - and no complex carbs, with some fat).

Thank you for that link!

I think I could easily jack up my carb intake with a couple more servings of yams and then see what happens. I do have the AACE guidelines (among other groups') - my medical nutrition prof has DM2 and was pretty good about instructing re: markers, but of course didn't talk about physiologic/pathological IR or low-carb diets.

Good advice, normally, but you'll see above that my blood glucose only hit 116 after a meal with rice and watermelon. It was the carb bolus of doom from waffle house that jacked it up to 184 (and then crashed to 63).

My experience was that I started to notice physiologic insulin resistance once I dropped to around 50 g carbs per day (along with numerous other health problems). I'm now closer to 100 g/day and I've never felt better.

Thanks, but I doubt it. I'm sitting at 19% body fat; I'm 27; I've never been overweight; my fasting blood glucose is 80. My blood glucose has been absolutely stellar postprandial, as noted above, except for after the massive Waffle House carb bolus. I am just trying to determine if anyone knows at what level of carb intake one can induce physiologic insulin resistance.

I checked it again and we're up to 184...I love how it's 3 hours postprandial and still on an upswing. Everything I know about DM1 and 2 I learned from my ADA-loving nutrition profs and textbooks, so this is beyond my knowledge level.

Yep, in shape. Never been overweight. No diabetes in the family history. Mild PCOS, which allegedly carries with it some degree of insulin resistance. Possibly sluggish thyroid or adrenal fatigue, but haven't explored that with a doc, yet. You're probably right about it not really mattering.

My first recommendation is to stay away from the Waffle House.

My second recommendation is to experiment on yourself. It is very possible that you created physiological insulin resistance by being low-carb. You can flesh it out by experimenting on yourself.

Here is a link to a self-experiment: http://www.diabetes-warrior.net/2012/05/03/dear-pancreas-you-may-rest-now-glucose-tolerance-test-results/

He has several posts that can be found by fishing around a bit on his site. He used a continuous glucose meter, but it can be done with a standard glucometer. Current American Association of Clinical Endocrinologists guidelines suggest below 140 1 hour post-prandial, below 120 2 hours post-prandial, and below 100 fasting. Play around with your diet some and continue testing. If your levels don't meet AACE guidelines, it would be worth seeing your MD.

You don't have to be overweight or have a family history to develop T2 diabetes.

Go back to eating your normal amount of carbs and do the test again. If it registers as more normal it may have been related to the extreme ingestion of carbs.

Really, there is no way of knowing without knowing more about you. Are you in shape? Does your family have a history of diabetes related to genetic defects?

I don't know much about insulin resistance related to low-carb dieting, but if the theories are true then it's just like being fat adapted. Your body prefers one type of fuel over the other and has a hard time handling a drastic change in intake. As long as you don't plan on eating Waffle House every day it probably doesn't matter either way.

What are your fasting numbers.Start from there. Normal Fasting Blood Sugar A truly normal fasting blood sugar (which is also the blood sugar a normal person will see right before a meal) is

Between 70 mg/dl (3.9 mmol/L) and 92 mg/dl (5.0 mmol/L) .

Doctors consider any fasting blood sugar between 70 mg/dl (3.9 mg/dl) and 100 mg/dl (5.5 mmol/L) to be normal. But several studies suggest that people whose fasting blood sugar is over 92 mg/dl (5.1 mmol/L) are more likely to be diagnosed with diabetes over the next decade.

Post-Meal Blood Sugar (Postprandial) Independent of what they eat, the blood sugar of a truly normal person is:

Under 120 mg/dl (6.6 mmol/L) one or two hours after a meal.

Most normal people are under 100 mg/dl (5.5 mmol/L) two hours after eating.

Reguardless of what you eat your glucose levels should never go over 140.

I did not see if you said you are diabetic , so here is my thoughts , You are prediabetic,,

If you need to know what to do , contact me on yahoo answers as Ben Trolled.

My experience was that I started to notice physiologic insulin resistance once I dropped to around 50 g carbs per day (along with numerous other health problems). I'm now closer to 100 g/day and I've never felt better.

I'm a Type 1 diabetic so I've been tracking my BG for years. When I eat at least 100 g of carbohydrate per day, 1 unit of Humalog insulin will be sufficient to cover 20-25 g of carbohydrate. If I restrict my carb intake to 50 g/day 1 unit of Humalog will cover only about 15 g of carbs. Eating more than 100 g/day of carbs did not result in any improvement in insulin sensitivity.

Dualhammers, I never stated that Type 2 diabetes is caused by by diet and not hormones or genetics so I don't who you are responding to. I also never said that Blossom1 HAS Type 2 diabetes, only that she fits the diagnostic criteria for either Type 2 diabetes OR prediabetes.

You could try upping your protein a bit and may ditch the white rice. See if it spikes as much.

Good advice, normally, but you'll see above that my blood glucose only hit 116 after a meal with rice and watermelon. It was the carb bolus of doom from waffle house that jacked it up to 184 (and then crashed to 63).
