blood sugar lows

Coconut Oil Fast is Over 11

My seven day Coffee, Water and Coconut Oil Fast … turned into only four days.

Note: I am a drug and insulin free Type 2 Diabetic.

I ended the fast early because….

1. The main reason was Blood Sugar Lows.  As you can see from the picture below … as expected my blood sugar was trending lower each day.   My fear on the evening of the fourth day … was waking up with a sub 50 mg/dl blood sugar reading.

I placed an asterisk on the 74 to note that I ate more Coconut Oil & Coffee than normal, to raise my blood sugar.  As you can see, it did not last for long.

What was a unexpected surprise was the lack of stabilization in my blood sugars. I expected an occasional dip into the the 60’s … but fully expected a stabilization in the 70’s.

It could be that, I just did not give my body long enough to adjust…. I definitely expect to ‘re-do’ this fast in the not too distant future.

Other reason…. I stopped my fast?

Poor planning – when I excitedly decided to attempt this fast, I did not realize that the 6th and 7th days would fall on a Holiday Weekend!!! lol

IF you think eating meats and veggies is tough at holiday gatherings while others eat pasta, breads, cookies and cakes…. imagine ME sitting sitting there with my coconut oil & coffee while the carb carnage commences. LOL!

EVEN this would not be enough by itself… but coupled with the low Blood Sugar … it wasn’t worth it for me.

Lessons Learned

1) Blood Sugar Affect … this lesson is OBVIOUS … a ‘saturated fat only fast’ … will definitely lower your blood sugar…. or at least it did mine.

** IF my blood sugar was routinely above 100 mg/dl …

a) I would go Very Low Carb sub 20g per day. If Blood sugar remained high …

b) I would go Zero Carbs from plants.  Only eat meats, eggs and cheese. If blood sugar remained high.

c) I would eat only saturated fats such as Coconut Oil and Ghee.


2) Strength and Stamina Affect – as my blood sugar went sub 70 mg/dl and especially sub 60 mg/dl … I lost all desire to exercise and I definitely felt tired and lethargic.

But this was to be expected … the real test was to see the affects after a week of fasting. Could I equal my personal highs in certain fitness exercises. In other words, did I lose strength and endurance?

This question can’t be answered now, it will take a couple of days for me to determine… but I doubt that much loss occurred since I only completed four days of the fast.

3) Wanna lose fat??? Eat Saturated Fat.   In four days… I lost over 4 lbs … and it ‘left’ at a rate of a lb a day.


Wrap Up

THANKS TO ALL for the support during the fast… it is and was greatly appreciated. :)

I am disappointed in the low blood sugars and that I ended the fast early …  no matter how trivial … ‘quitting’ is not something I enjoy.

However, all is not lost, I did learn from the experience AND I finally experienced a blood sugar ‘LOW’.  Until this experiment… I had never felt a low blood sugar level. Now I can at least know what people mean when they talk about it.  Granted… many of my diabetic friends have far exceeded a “53mg/dl” and have experienced much worse side affects. :(

    I drink such coffee every morning but also add heavy cream. I think the flaw in your “fast” is that it lacked protein. If you added enough protein to meet minimal glucose needs of the 5% of your body’s cells which cannot utilize ketones instead, you should have been fine. You liver is capable of making more than enough glucose (from ingested protein) for these needs, but they most have some incoming protein to do it with otherwise your body might begin destroying your mucsles, clearly not a good thing. A zero-carb “fast” like the one you did but with some protein should be viable without limit and should bring about the desired BG stabilization in the 70s and 80s.

    Even if you didn’t quite meet your goal this time, you still learned from the experience, and that’s pretty kickass.

    Even cooler (to me) is that you know what going hypo feels like. It’s always interesting to try and explain to people, especially because it comes with so many different symptoms depending on my condition that day.

    Wow, this experience almost exactly replicates my experiment about two years ago. My reasoning was that coco oil would transition me faster into ketosis and minimize muscle cannibalization in the initial phase of the fast when I’m still on glucose metabolism. I can’t stand to eat coco oil “neat” so I mixed it in coffee…. on either the 2nd or 3rd day I began to have a intensely pounding pulse, to the point it scared me. At the time I had no glucometer but I did suspect LBG-and indeed, after munching a little crackers and candy the symptoms abated.
    So it appears coco oil has powerful BG-lowering abilities, at least in isolation, since simple water fasting doesn’t appear to lower it so dramatically, but I’ve seen little about that in the literature. Now I am wondering if taking some before bedtime can address the DP issue. Has anyone had any experiences with coco lowering BG when used with food?

      Unless I am ‘experimenting’ I eat coconut oil every day with food, and I typically have normal Overnight Fasting Blood Sugar, 70-100 mg/dl.

      I need to try a water fast and see if my Blood Sugar Drops steadily as it did with the Coconut Oil alone … that may be my next test. :)

    Thanks for the feedback– I am going to try coco oil in the evening and see if it can impact my pretty crappy AM readings (140-160), which, unlike PP highs, don’t respond to or are even exacerbated by exercize.

    Hello–thanks for the encouragement! Mindful of your bad timing experience, I decided to postpone any experiments till after the 4th of July “carb carnage” (I have two T2 parents who are poster children for the last couple of decades of conventional treatment/nontreatment of T2). Planning on a brief (3 days max) coconut/coffee fast next week, have just been trying cut the carbs and work some coco into my diet this week. Powerful stuff–seems to accelerate my pulse and can disturb sleep if too much to late, unless I’m just imaging stuff. I’ll be sure to report back.
