Potato Starch Day 2: Waiting to Explode

This morning, I mixed a teaspoon of Bob’s Red Mill potato starch into a half cup of full fat goat milk kefir and drank it up.   I’m already getting more used to pungent taste of the Kefir.  I’m still waiting for the gassy bulletproof explosion or crazy sex dreams that I’ve been warned about.  So far neither has happened.

In the afternoon, my new probiotics arrived: Primal Defense Ultra and Prescript-Assist.   I haven’t researched these probiotics much. I’m following the leaders at FreeTheAnimal on this one.  They really look like soil when you break them open.

I was so excited about the new probiotics and lack of gas that I had to make another kefir drink for dinner. How does “kefir gut bomb” sound?

Mix with immersion blender for frothy goodness.

Food Diary:

Breakfast: 4oz goat milk kefir, 1tsp potato starch, 2oz butter, 1/2oz MCT oil
Lunch: 2oz sprouted almond/mulberry trail mix, 2oz butter, 1/2oz MCT oil
Dinner: 5oz lamb, homemade broth, 4oz goat milk kefir, 1tsp potato starch, 2oz sprouted trail mix
Snacks: 1/3 bar of dark chocolate, 2oz semi-sweet chocolate, bag of seaweed snacks, few tsp honey, some macadamias, more sprouted trail mix

Total calories: 2476 kcal

Ketosis: Based on the ketostix, I was in a strong ketosis in the evening after dinner.  In the late evening I snacked on some semi-sweet chocolate chips and was not in ketosis in the morning.

Weight: Down 0.8 lbs from 215 to 214.2 between day 2  and 3.  (I’m a 5’8″ male for reference).  Today is also weekly measurement day for me.  242 inches total for 8 sites.

GI: Amazing on both day 2 and day 3.  Zero gas and great BMs with good volume after a month of IBS-D like GI distress.  On day 2/3 at only 2 tsp PS, the credit here goes more to my restricted food choices rather than the potato starch.

FBG:  86mg/dL in the morning of day 3.  This is a great number for me.  After a night with some sweet chocolate I might see a swing in either direction but not today.  Don’t worry I plan to test this with much bigger PS+carb intakes.

The Potato Starch Craze

I dipped a toe into the potato starch craze yesterday.

1/2 tsp of Bob’s Red Mill mixed into half a cup of full fat goat milk kefir.  I used an immersion blender to mix it.  Helps give it a nice froth.

Results: No gas, no bloating, and healthier digestion this morning than I’ve had all week.

Much more to come.  I moved up to 1 tsp this morning. Soil-based probiotics should be arriving in the mail tomorrow.

A Year of Blood Glucose Testing

I’ve been playing with a Precision Xtra glucometer for about a year now. I bought 50 test strips and used them throughout the past year.  My goals were:
  1.  Identify what sort of metabolic damage I have
  2.  Identify a way of eating that will generally keep my blood glucose as low and tight as possible.
I was inspired by this Chris Kresser post:“How to prevent diabetes and heart disease for $16”

“Test your blood sugar first thing in the morning after fasting for at least 12 hours. Drink a little bit of water just after rising, but don’t eat anything or exercise before the test. This is your fasting blood sugar level.

  1. Test your blood sugar again just before lunch.
  2. Eat your typical lunch. Do not eat anything for the next three hours.Test your blood sugar one hour after lunch.
  3. Test your blood sugar two hours after lunch.
  4. Test your blood sugar three hours after lunch.
    …. On the third day, you’re going to do it a little differently. On step 3, instead of eating your typical lunch, you’re going to eat 60 – 70 grams of fast acting carbohydrate.

Then he sets some ideal results (mg/Dl):

Fasting blood glucose: <86
1 hour post carb meal: <140
2 hours post carb meal: <120
3 hours post carb meal: baseline

I was also inspired other N=1 experiments from Jimmy Moore with Nutritional Ketosis and the BJJ Caveman’s work with nutritional ketosis/carb nite.

I did not design a very good experiment though.  I never came close to 3 consistent days of testing like Chris describes.  The data I collected has major problems.  First, I didn’t even consistently test fasting blood glucose as opposed to mid-day or evening readings.   Second, my diet was very inconsistent.

 
Some observations after a year of playing with the glucometer and 50 strips. I used about 25 strips in 2013 and another 25 in 2014.  All numbers are mg/dL:

  • My average BG in 2013 was 92 without much carbohydrate restriction.  Highest BG was 115.
  • My average BG in 2014 was 84 while restricting carbohydrates to <50g on most days.  Highest BG observed was 95.
  • 3-5 days of low carb dieting seems to drop my fasting blood glucose into the 60-70 mg/dL range
  • When eating carbs with each meal, BG seems to float around 100-110 throughout the day
  • When restricting carbs, BG seems to stay much closer to 80.
  • When restricting carbs, the day after a 250g-300g refeed my BG can vary greatly.  It might be 10 points higher than average or it might be 10 points lower than average the next day.
  • 60-70 feels different depending on how many days I have been since a large carbohydrate load. The day after a refeed I might have cold hands/feed and be tired at 65.  3 or 4 days afterwards it might not bother me at all.
HbA1c scores:
  • 5.4 in November 2012
  • 5.2 in May 2013
  • 5.5 in December 2013
I just ordered 100 more glucose strips and 30 blood ketone strips.  I’m looking forward to better using them for some more consistent testing of my cyclical ketogenic diet.

A Year in Unblogged Hacks

I want to provide only well-researched or quantitative material on this blog.  I took a year off blogging to try and achieve those things and to be sure, it’s not going well.  So I’m back anyways and I’ll be sticking to things I excel in: personal experience based on sketchy data and speculation.

Since I’ve been gone I’ve been:

  • Trying out the Precision Nutrition Lean Eating Program
  • Taking an organic chemistry lecture and lab to help me better understand the science of nutrition
  • Experimenting with the “Perfect Health Diet” and long diet break in 2013
  • Experimenting with a cyclical ketogenic diet in 2014
  • Working on my digestive issues
  • Focusing on my sleep
  • Exploring different emotional and psychological strategies
  • Meeting Mark Sisson at PrimalCon Lake Tahoe and Chris Kresser at his book signing in Berkeley
  • Attending meetups in the San Francisco Bay area ranging from Paleo to Biohacking to Futurism

Coming up I’m excited about PaleoFX in a few weeks.  I’m also looking forward to trying my hand at some hands-on biolab work at the Berkeley Biolabs.
