Two weeks ago, I told you about the series of Frankenstein-like diet/blood sugar/insulin experiments that I am conducting on one of my personal training clients-  in the article Make Insulin Your Friend… and Get Leaner, Stronger & Healthier.

This week, I am going to show you the results of the first experiment and tell you how I took my human guinea-pig and made him Pre-Diabetic in less than 7 days.

Experiment #1 – The “Normal” Diet

I asked my client / test-subject to:

  1. Stop his normal exercise routine (allowed to go on nightly walks with his wife)
  2. Eat like a “normal” person…. ie I told him that he could eat whatever he wants, whenever he wants with no concern for nutrition.

[box type=”note”]I told him not to pig out on junk food – just to eat like the other people in his office. In fact, he modeled his diet after one of his co-workers – a 190 lb, skinny-fat kind of guy.[/box]

Here are some examples of what he ate last week.


  • Bowl of Rice Krispies and a mug of coffee, or
  • Buttered bagel & coffee, or
  • Egg McMuffin with Hash Brown and coffee
  • 1 Donut & coffee


  • Sandwich, Coke & cookie, or
  • Slice of pizza and bottle of water
  • Rice, veg & chicken from food court Chinese place
Afternoon Snack


  • Pizza, salad and a beer
  • Pasta & garlic bread and a glass of wine
  • Steak stir-fry with rice & tons of veg

Blood Test Info

I had him test his blood throughout the day using a blood glucose monitor (supplied free of charge by Roche Diagnostics):

  • Upon waking – fasted blood test
  • Before eating
  • 2 hours after eating
  • Before bed

[box type=”important”]What we found is that other than the fasted blood test (taken first thing in the morning), his blood sugar levels were moving around too much to come to any sort of conclusion…so we’re just going to report on the fasted blood tests[/box]

Blood Test Results

  • His pre-experiment fasted blood sugar levels ranged from 4.4 to 4.7.
  • His pre-experiment diet is a modified Paleo-style diet where he is allowed to eat potatoes and small amounts of legumes
During the experiment, his fasted blood sugar levels were as follows:
  • Day 1: 5.5 mmol/L
  • Day 2: 5.9 mmol/L
  • Day 3: 6.2 mmol/L
  • Day 4: 6.4 mmol/L
  • Day 5: 6.5 mmol/L
  • Day 6: 6.9 mmol/L
  • Day 7: 6.7 mmol/L

And as you can see from the chart, this places our test-subject squarely in the Pre-Diabetes range…on his way to full-blown Type 2 Diabetes.

All in one week.

Not good.

And he felt like crap the whole week.

  • Waking up with a headache 5 of the 7 days
  • Craving carbs like crazy
  • Never feeling full, while…
  • Often feeling nauseous

At the end of the week, he was glad to go back to eating healthy


This week, we are experimenting with a grain-free diet.

I will post the results next week.
