Intermittent Fasting – The No Hunger Method | Critical MAS

Intermittent Fasting – The No Hunger Method | Critical MAS

I started doing Intermittent Fasting over three years ago. My strategy has always been to just deal with the hunger. If you ignore it, it goes away. When I first began fasting, I’d think about my hunger constantly. These days, it barely grabs my attention.

Recently, I was inspired by a post over at my favorite nutrition website Perfect Health Diet to try an alternate approach to Intermittent Fasting.

Before I go into the changes I tested, let me go over two benefits from Intermittent Fasting.
  1. By restricting carbohydrates for an extended period, you can shift your body into a state of ketosis. Ketosis has a host of health benefits. One of which is you burn fat at a quicker pace.
  2. By restricting protein, you can trigger autophagy. This is the process where cells consume and recycle their own damaged material. This results in many health benefits, including life extension.
The Perfect Health Diet post Ketogenic Diets, I: Ways to Make a Diet Ketogenic is a detailed explanation of the ketogenic metabolic pathway. The part of the article I found most interesting was how the use of coconut oil, which is loaded with short chain fats, can accelerate the production of ketones.
This means that if you eat a lot of coconut oil (which is 58% short-chain fats), you deliver a lot of fat to the liver for disposal. The disposal process for fat is conversion to acetyl CoA followed by either burning in the TCA cycle or conversion to ketones.
Since that post was written, I have done many fasts where I consume nothing but 1 to 3 tablespoons of coconut oil. I find it has a slightly sweet taste and it does lower my hunger level. To confirm I was still hitting ketosis, I used Ketostix to measure ketones. After a 16 hour fast with coconut oil, I was measuring Small to Moderate ketones. Pretty cool.

Well coconut oil by itself may not be enough for the hungry. Have no fear, the Perfect Health Diet book came up with another idea. It said you can consume fermented vegetables on a fast. Wouldn’t the carbs from the vegetables interfere with achieving ketosis? Nope. From the book:
Most vegetable carbohydrates are intercepted by gut bacteria, which digest vegetable fiber into short-chain fatty acids.
If the book is correct, I could eat coconut oil and sauerkraut and still go into ketosis. I decided to test it out.
  • Monday night: My last food intake was at 10 PM.
  • Tuesday 10 AM: 1 tablespoon of coconut oil, 100 grams of cortido sauerkraut.
  • Tuesday 1 PM: 1 tablespoon of coconut oil, 100 grams of ghost pepper sauerkraut.
The cortido sauerkraut has some carrots, so I was concerned that those carbs might be enough to prevent ketosis. But it didn’t. At 2:30 PM, I tested Moderate ketones on the Ketostix. Victory!

Cortido Sauerkraut – Ketosis never tasted so good!

So if you’ve put off Intermittent Fasting, because you can’t deal with the hunger, you now have no excuses.

Get yourself some coconut oil and make some fermented veggies.

    I have done 2 fasts so far. Only for autophagy purposes. I haden’t eaten anything for about 21 hours in both instances. I just kept busy and drank a lot of fluids and was fine. It is probably good to feel hungry every once in a while. I can tell you, no matter what I eat at night after a fast tastes GREAT and I eat like a ravenous animal. Haven’t lost weight either which is fine by me.

    Still doing IF once a week, MAS (doing one today as a matter of fact). I have not had a cold/flu/sinus infection since starting them 2 years ago :)
    I have not tried the coconut oil part but might start that shortly.. take some after the 15 hr fast for women that you recommended or at the 13/14 hr mark?
  3. MAS
    @TigerAl – I would mix it up. I am a big fan of randomness when it comes to fasting. Everybody is different.

    This post is really interesting. The idea that coconut oil and femented veg won’t disrupt ketosis has given me some great “food for thought.”
    I recall Mat Lalonde saying that his breakfast was often 1/2 cup of coconut milk, which provided a sense of satiety but, he believed, didn’t interfere with autophagy. Not sure whether the carbs in the coconut milk would be sufficient to disrupt ketosis, but there’s only about 6g in a 1/2 cup, so I’d be inclined to doubt it.
    With the colder weather coming on I am ramping up my IF again. For October I’m starting back easily with just two 16-hour fasts a week. The number of weekly fasts will increase throughout fall, followed by increasing their duration in winter.
  5. MAS
    @Geoff – That is exactly the same strategy I follow. Less daylight, less carbs, more fasting.
    Coconut Milk has almost no protein, so Mat is probably right in believing it wouldn’t interfere with autophagy. It is the amino acids in protein that interrupt autophagy. As for interrupting ketosis, that might vary from person to person as well as the timing of the beverage.

    hi,
    I have been doing my own little version of this, but
    with romaine lettuce and olive oil, as a meal for dinner
    only. Just as a light three day thing.
    Problem, as I was re-checking my data on romaine lettuce, I was dismayed to find that it has a substantial amount of sugars. I don’t know if this interfered with ketosis as I can not afford keto sticks.
    But, I do feel like I am in ketosis.
    What do you think of romaine lettuce as part of this “experiment” ?
  7. MAS
    @Sheila – I don’t have an opinion on romaine lettuce. Perfect Health Diet does make a convincing case for using coconut oil over all other fats.
    Ketostix are dirt cheap at Wal-Mart.

    Cool experiment – thanks MAS.
    I gotta admit though that I’m concerned about the possibility of over-consumption of coconut products. I doubt my genetic line (Northern European) feasted on coconuts over the past few millenium – but who the heck knows…
    I suppose I could try to replicate the experiment with pork lard and/or duck fat…

    @GWhitney – I think butter might work better. It is the short-chain saturated fats that seem to accelerate ketone production. Worthy of test though!

    I have been doing IF with coconut oil a few times a week for the past two weeks. This week I broke out in a horrible rash. I have eaten coconut oil for years though by cooking with it but this is the first time I am eating it straight. Why do you think it is having this effect on me?
  12. MAS
    @Shannon – That is new to me.
  13. That’s a find, Mas. Anyway, I prefer water-only fasts. The simplier – the more chances it works.

    @Alex – Water fast are great too. One downside to fasting is that feeling of getting cold. By consuming saturated fat, you can stay in ketosis and increase your body temperature.

  16. What types of Intermittent Fasting do you do? For example is there like one day a week where you don’t eat anything (besides the above mentioned coconut oil maybe), or do you not eat from 12am-12pm.
    Just curious, thanks!

    @Becca – I vary the strategy. However, these days I mostly do 14-16 hours fast with a small amount a fermented veggies and coconut oil. I fast more in the winter months and less in the summer.
  18. MAS
    @Becca – My eating window is usually 2PM-10PM. The kimchi and coconut oil is consumed around 8AM-10AM.
  19. Very interesting. I’ve been trying out a 12pm – 9pm eating window… but find that I often get very hungry around 1am. Like the hunger will wake me up… think i might try just eating a little coconut oil when this happens.
    Thanks!
  20. MAS
    @Becca – I have the same issue. I must eat right up until the moment I go to sleep or I wake up hungry. Quality sleep is more important than fasting.

  23. Steve
    I thought coconut oil was medium chain fatty acids rather than short chain?
  24. MAS
    @Steve – Good point. PHD has it at 58% short chain. The Wikipedia says it is 66% Medium chain. Something isn’t adding up. I’m going to contact PHD.
  25. MAS
    @Steve – I got the answer. Paul explained it in his comment thread.
    “… short chain fats in our lingo encompasses the standard “short-chain” and “medium-chain” — 12 carbons or fewer. Since they’re handled similarly biologically, we thought it made more sense to use a descriptive term instead of technical jargon.”
  26. Steve
    Makes sense. Comparing with long-chain fatty acids found in most saturated fats coconut oil, which also contain saturated fat, has short chain fatty acids in comparison but not as short as some other fatty acids. At least that is how I am making sense of this.
