Blood Glucose testing – Splenda and my BG levels

One of the things I had always wanted to do is validate some of the things I believed with something I knew.  That is how certain things like sugar free desserts I make or sugar free soda might affect my blood glucose levels.  I know this has been in vogue recently with both Jimmy Moore with N=1 experiments (Julian bread being the latest test) and Hank Garner of Low Carb Journey fame doing similar tests.  I also wanted to continue to track what my blood glucose was on a more routine basis than once a year with my annual physical.

Prior to starting Atkins, I was told I was in danger of getting diabetes and my blood glucose levels were apparently borderline.   Being an EMT, I have taken my blood glucose before, and in the past, it has been in the 70s.  Being somewhat in the public eye about my low carb lifestyle, I get the cynics who say my lifestyle makes me more insulin resistance and lowers my sensitivity, i.e. more likely to get diabetes, so I wanted to have personal knowledge of where I was currently at.

To this end, I purchased a rather cheap diabetes starter kit to do my testing.  The meter similar to the photo above, lancets, AND test strips were only $8.  I thought that was quite reasonable entry to gain the knowledge I wanted.  I have tested my blood glucose 3 times now, and it was in the low 70s.

However fasting blood glucose was not the real reason for my buying the monitor.  I wanted to test my reaction to common foods.   This past Saturday was my first test.  I wanted to test how sucralose (Splenda) and Acesulfame Potassium (Ace K) affected my blood glucose.  My first blood glucose reading was 70.  I then drank 32 oz of Fastco (Fareway store brand) Flavored Carbonated water over the course of 10 minutes.   I then tested in 30 minutes (BG reading 76) and 60 minutes (72).  Both are well within the margin of error, and in either case don’t demonstrate a large impact of 4 servings of the drink.

    Sensitive subject on the Low Carb Boards!
    People fight over this one!

    I did the same kind of readings…
    Got the same results as you.
    It didn’t raise me blood sugar levels much at all.
    Some people maybe it does!

      Didn’t realize I was diving into a minefield, but I honestly see no problem in getting more information about how foods affect you. The only thing I am out is $10 for testing equipment, and I gain a ton in knowledge. If I could test my cholesterol or other body items as cheaply, I would make a routine (quarterly) of testing myself for that. It’s like weighing every day or every week or every month. If the cost is marginal, then why would you not test.

    I love this kind of information — thanks for sharing. Do you know why Dr. Atkins plan is does not allow aspartame? Is it because of blood glucose, or that it stimulates carb-craving? I’ve wondered if anything has become known since his passing that would have changed the plan. Diet Pepsi is my weakness!!! Thank you for your tireless efforts on behalf of a wonderful lifetime way of eating. Your videos and recipes are a major factor in the way we eat.

      The aspartame caution was primarily due to Dr. Atkins seeing a large percentage (seems to me it was 25%) of people who stopped losing while consuming aspartame. He theorized that there was a cephalic insulin reaction happening as they were eating it. I am glad you like the videos, Barbara.

    Oh I agree! Love learning new things!
    Super good post!

    Thanks. Very interesting. I drank a diet rite soda which Splenda sweetened and I seem to be ok. No cravings for another, or carbon rich foods.

    Hello I have noticed since I started low carbing that my morning readings are like 108-115 . Before low carbing it was always under 100 . Do You have any idea why that would be hapening ? Also I wanted to ask what your thought on this 0 carb 0 calorie sweetner is this is the ingredients
    Water, Sodium Saccharin N.f. 2.5%, Benzoic Acid and Methyl Paraben As Preservatives.
    here is the link

    Could this be causing stalls ? I hope not because it is the only sweetner I will like ,also I know we dont count calories but how many do you take in in a day ? I know this is alot of questions ,but then again you are the man !!!!

      Those are somewhat high readings – 125 and above would put you in the diabetic category. How long have you been low carbing? It could be your body is still normalizing itself. I am not a doctor, but if it continues, I would see a low carb friendly doctor. I would aslo evaluate what your blood glucose would do after eating (30,60,90 minutes). Is it still high?

      As for your sweetener, it is essentially liquid saccharin, and while I would necessarily use it (not sure of how well it would perform in cooking), it *should* be fine. However if you are stalling, one of my first steps would be to eliminate the artificial sweeteners. As for Calories, my daily intake varies from 2000-3000 typical Calories.

    I have been on low carb since Sept and am losing very slowly I think . My Blood sugars are fine all day . usually 95 or so . I have checked after eating and it is like 101 or it will go down a bit or stay the same . I only use the sweetner in my coffee and my almond milk . Thanks for everything you do !!!

    Hi!
    Can you do this test with your Flax meal bread? (http://www.youtube.com/watch?v=DX7wrTX8ybQ). I always eating that bread, and I’m curious how much it affects the BG level. But unfortunately I don’t have a glucose meter. Please do a test with the flax bread!

  • ffixer

    Thanks!
    Please write the results here, after you checked it.

      Will be writing a new post on this, I had one full recipe (two servings) of flax bread this morning with one slice of swiss cheese (.6g of Carbs), so the nutrition facts for the bread were: 210 Calories, 20g Fat, 4.8g Carbs (4g Fiber), 8g Protein.

      My fasting blood glucose score was 82. 30 minutes after eating the bread and cheese, my blood glucose score was 90. In thirty more minute (or 60 minutes after), the blood glucose was back down to 83. It is safe to say the bread had very little affect on my blood glucose levels.

    I’m curious about your experience about this too. I just discovered that my blood sugar went from 81 to 96 after just an Atkins bar. Apparently I am sensitive to the sugar alcohols…

    I was asked to test this, so I wanted to report my findings. I will be writing a longer post on this later, but I wanted to release my provisional findings now. I had one full recipe (two servings) of flax bread (http://www.youtube.com/watch?v=DX7wrTX8ybQ) this morning with one slice of swiss cheese (.6g of Carbs). The nutrition facts for the bread were: 210 Calories, 20g Fat, 4.8g Carbs (4g Fiber), 8g Protein.

    My fasting blood glucose score was 82. 30 minutes after eating the bread and cheese, my blood glucose score was 90. In thirty more minute (or 60 minutes after), the blood glucose was back down to 83. It is safe to say the bread had very little affect on my blood glucose levels.

    Thanks the answer!

    From this post I went to check out your Flax Bread — can’t wait to try it. Have you tried freezing it with any luck???
