How are we “Wired to Eat”?

After reading Robb Wolf’s book, Wired to Eat, I decided to go ahead and follow his experiment that entails eating various foods and measuring my glucose levels.

The idea behind it (as I understand) is that a sustained spike in glucose after a meal could indicate some kind of problem with the food consumed.

What’s a sustained spike? Well, the recommendation is to test two hours after eating.

More specifically, Robb recommends eating 50 grams of carbohydrates in just one carbohydrate-rich food at about the same time every morning for breakfast.


Food-Glucose Response Test Summary:

  1. Pick one food to eat.
  2. Measure a portion of the food so that it contains 50 grams of carbs.
  3. Eat it for breakfast (with nothing else).
  4. After two hours, test your blood glucose.


The Tools:

Blood Glucose Monitor:

Simple Scale:

Carbohydrate Calculator:


Day 1: Bone Broth

91 = fasted blood glucose, 10/2/2017 7:35:00

86 = two hours after eating – blood glucose, 10/2/2017 10:37:00

This was just an experiment because I didn’t have any carbs ready to go for testing. And I already started heating my bone broth – blended with Kerrygold butter and Bulletproof Brain Octane c8/MCT oil.

I’m not sure why my glucose was a bit higher today. Perhaps due to something I ate the day prior?


Day 2: Sweet Potatoes, mashed

76 = fasted, 10/5/2017 7:49:00

78 = two hours after eating, 10/5/2017 10:30:00

Good news! No issues with sweet potatoes 🙂


Day 3: Yellow Finn Potatoes, mashed with sea salt

78 = fasted, 10/6/2017 7:24:00

60 = two hours after eating, 10/6/2017 10:14:00

Whoa, 60? Is that even safe – or normal?! I just looked it up and the Mayo Clinic states:

A normal fasting blood glucose target range for an individual without diabetes is 70-100 mg/dL (3.9-5.6 mmol/L).

What changed? The slight variations this time were:

  1. Bouncing on my rebounder for five minutes while doing breathing exercises (ie, my normal morning routine that I have skipped lately due to this experiment)
  2. Adding sea salt to the food

I think I may have to retest but, unfortunately, these potatoes came from my CSA (Community Supported Agriculture) box and I’m all out!


Day 4: Plantain Chips

86 = fasted, 10/19/2017 7:14

94 = two hours after eating, 10/19/2017 9:45:00


So there were a few somewhat interesting things that happened in today’s experiment.

  1. +8 point increase. So far the biggest jump in glucose from fasted to post-carb has been just 2 points.
  2. The measurements seemed off. What was listed on the nutrition label of the package didn’t seem to match my calculations. 28g of food per serving. 20g carbs per serving. I would need 2.5 servings to get to 50g of carbs. This is 70g of food. However, I emptied the entire contents onto my scale and it came to just 75g. And there are 5 servings in a bag. The entire bag should be twice that based on my calculations. Strange.
  3. One other thing I did differently was my 5 minutes breathing-rebounding 20 minutes after eating. I thought this would LOWER my glucose more than in other experiments in which I’ve made sure not to exercise.
