I usually say… “if you want normal blood sugars…Do as I do!” … not with this post.
Post Disclaimer: What I am going to describe in this post… I sincerely do NOT want you to do.
I am NOT suggesting this for anyone… especially not diabetics. I seriously considered not publishing it…
Before you continue reading… you must agree to the statement below, please. :)
Do not try this unless you are like me…
a) Are drug and insulin free
b) Have truly Normal Blood Sugars, sub 100 mg/dl over night fasting blood sugars (it’s assumed you follow a primal meal plan)
c) ** You have broken the carb (grains and sugar) addiction for at least two months.
… even still I do NOT recommend this… ok?
Testing Insulin Resistance and Glucose Intolerance … The Plan
Back in December I had a “Date with the Devil?“, it was a 24 hour experiment with very high carb. This is like that… only different. :)
* This is a TEMPORARY experiment.
** Luckily, I have a Continuous Glucose Monitor to record it … :)
(I am in Phase 3 now)
Phase 1 – Eating a strict, ‘low carb paleo’ meal plan for 30+ days. Here’s a post, “Nagging Question” but in summary I ate only meats and leafy green vegetables.
Phase 2 - Re-Adapting my body to carbohydrates…. or adding back the carbs. I gradually added back carbs in my diet.
Why am I doing it? In brief, for almost three years I have eaten a Very Low Carb meal plan. My body has adapted to burning ketones for fuel. To properly test my insulin resistance, I need to re-adapt my body to burning carbohydrates.
“… if you take an oral glucose tolerance test you will fail and be labeled diabetic.”
The quote above is from Petro Dobromylskyj’s excellent description of why in this blog post, “click here“. (Thanks to Michelle Trevino for reminding me of Peter’s Post) I totally disagree with the title and the phrase “Physiological Insulin Resistance”, I prefer to call it ‘carbohydrate sensitive’ instead. :)
Phase 3 – According to Peter’s protocol (I’ve read this on numerous Medical Industry sites as well) I will eat 150g of carbs for three straight days. Then on the fourth day I will take a ‘home version’ of the Glucose Tolerance test, I will consume 75 grams of sugar to test my insulin resistance and glucose intolerance.
I am actually in Phase 3 now.
To summarize why I am adding back carbs … Our bodies are designed to run on lower carb diets, of that I have no doubt. To test my body’s Glucose Tolerance, I must re-adapt my body to eating a higher carbohydrate meal plan.
… here is how that’s working for me. No shocker here… blood sugars begin to rise.
From the picture below you can see that I have indeed added back the carbs and as expected my blood sugars begin to rise.
Line 1 = my carbohydrate consumption.
Line 2 = My average blood sugars for the day using a Continuous Glucose Monitor (CGM). The unit reports my blood sugar levels every 5 minutes. Honestly, I do not like this experiment and will end the high carb phase in two days. What you can not see, is the high blood sugar spikes I have experienced after eating the carbs. I’ll definitely report more on all this as time allows.
1. Starting on April 25, I began adding starches to my diet, white potato and rice.
2. April 30th I performed a preliminary ‘home version of the Glucose Tolerance test.
3. Here is an explanation and more background on the Glucose Tolerance Test, in short it’s consuming 75 grams of sugar. At the end of two hours if your blood sugars exceed 200 mg/dl, you are considered diabetic. If you are below 140 mg/dl you are considered ‘normal’. If you are between 140 mg/dl and 200 mg/dl you are considered to have ‘impaired glucose tolerance’.
(I will post about that …and much more later)
* These results are from a Continuous Glucose Monitor (CGM). As several Type 1′s have mentioned (and as I have experienced myself) the CGMs are not 100 % accurate. In my experience, when blood sugars are steady the accuracy seems very good. However, when intense exercise or more carbs are consumed and blood sugars begin to rise rapidly, the accuracy seems to suffer.
** Even ‘standard’ blood sugar meters are not 100% accurate. Also, blood sugar levels are influenced by a wide variety of factors including foods, stress, sleep, infections and illness. Therefore, your experiences will be different.
There is only one real purpose for all this … so that I (and you) can learn from the experience.
The main thing I want to learn… am I still insulin resistant and if so, how much? … am I still technically a ‘diabetic’?
