Fasting

A mythology around food →

Reactions so far have been a combination of interest and concern. The prevailing belief does seem to be that humans require three meals every single day, and you deviate from this number at your peril – missing lunch or breakfast is survivable but worrisome, eating only dinner is masochistic, and eating nothing for a day is a sure sign of disordered eating or some other form of mental illness.

~ David Cain from, The Myth of Three Meals a Day

Most of the reactions I get are concern. I’ve zero interest however in what others think of how I eat. I’m still over-weight because I binge eat; I binge eat as a form of stress relief, and I’m okay with that. (It’s vastly better than other forms of stress relief which I am happy to remain free of.)

The really interesting affect of all my fasting is that it’s completely changed how I think about others’ eating. For a long time I would think judgmentally about others’ eating, and sometimes I’d even make the egregious error of voicing my opinions. But my fasting has taught me how annoying (and patently incorrect if I’m being honest) others’ opinions are about eating—and then “physician heal thy self!” I turned that into self-criticism about my thoughts regarding others’ eating. Not only do I no longer voice my opinions, I rarely even have thoughts about others’ eating habits. I didn’t simply learn to stop having an opinion, but I stopped thinking I know better.

Temperature matters →

The other evidence we have is animals who live in the cold have higher metabolic rates, higher activity levels, yet higher body fat and body mass than those that live in the warmth. This suggests that fluctuations in body fat may be tied to changes in temperature exposure, and not just to protect us from famine. The bottom line is temperature matters.

My pull-quote is from the very end of Pilon’s article. Overall it lays out a delightful overview of the main systems that regulate our body composition. I love this last point—the part I’ve quoted—because it has nothing to do with humans; It’s a nice “and the same thing seems to be true for other mammals” that provides a great reality check on the models he’s presented in the article.

Pilon is the author who made things clear and simple enough for me to try intentionally manipulating the window of time each day when I stuff food in my face. Being intentional about that greatly increased my awareness of subtle signals from my body. At 8:30am, when I’m day-dreaming of blueberry pancakes, am I actually hungry or am I simply having a craving for carbohydrates? And when I wake up at 1am with a massive cramp in my left calf… I should probably have remembered to take my magnesium supplement before bed, and I better eat a banana first thing in the morning.

Another factor to consider is that this was a study in “lean” adults, and it is possible that results would be different if the investigators included people who actually need to lose weight.

~ Peter Attia from, Is alternate-day fasting superior to calorie restriction for fat loss in lean adults?

slip:4upeia1.

Some times I read stuff that is really disappointing. (This is one such case, don’t bother clicking through.) Attia’s content is almost entirely really good… no idea what happened here.

My BMI is currently above 33. Say what you will about BMI—but, please don’t, I know what you’re considering telling me—but I am over-weight. I should drop 20 pounds. Then drop another 20 pounds… and guess what. I still wouldn’t be down to a BMI where they’d let me into the study Attia was writing about. What— why would you do a weight-loss study on people whose weight is, (according to BMI,) normal?? Face palm.

Here’s what I know about alternate day fasting: It really works if you are fat, (like me.) Presuming your body can metabolize fat—caution, the average western diet down-regulates that ability to near zero… But presuming your body can metabolize fat, a day of not eating is pleasant. I’m serious. And then the second morning, 40+ hours of not eating, I’m actually hungry. Meanwhile, my body just used up thousands of calories of fat. Then I simply go back to eating. Anyway. That’s my experience.

Protein allocation →

Published April 2, 2022  ·  All posts on Apr 2  ·  

By definition LC is about dietary carbohydrate restriction. If you are reducing carbohydrates, your proportional intake of protein or fat, or both, will go up. While I don’t think there is anything wrong with a high fat diet, it seems to me that the true advantage of LC may be in how protein is allocated, which appears to contribute to a better body composition.

Zoinks! This short article is dense. I read each paragraph. Then slowly reread the paragraph, squinting slightly and turning each sentence over in my mind. It feels like there’s at least one actionable-item, (something to start doing, or something to stop doing,) in every paragraph. I’ve spent a lot of time in recent years trying to learn what I can about all the things in this article. It’s a beautiful assembly that backs up the thesis in the first paragraph, (which is quoted entirely above.)

Fasting is nothing more than intentionally restricting what, or when, you choose to eat. Over the years I’ve posted a good bit about fasting. If this is new to you, start with my post, Ten years and About that diet.

In my battle with depression, I’ve become convinced that inflammation is a causal factor; being over-weight is generally inflammatory and then eating inflammatory foods can tip me over into an acute episode of depression. To be clear: I’m literally saying that if my weight is up, and I eat the wrong food, the following day will be a shit-show of depression.

If you have no idea what I’m talking about—AWESOME. I’m so happy for you. (That’s not sarcasm.)

…okay, you’re still reading. Here’s something new [as in: I’ve not posted this URL on my blog before] from Pilon:

I’ve found stats saying it’s the 4th leading cause of disability worldwide and that mood disturbances including depression will lead to an epidemic of disease in the 21st century in the western world. It’s clear that depression needs to be addressed more often than it currently is in the mainstream and health and fitness media. I find depression particularly interesting because of the connection with inflammation.

Curious, it’s almost as if what I eat matters…

§11 – Intermittent Fasting →

This entry is part 11 of 13 in the series Changes and Results

Intermittent Fasting (IF)

With any form of IF, you can get the same physiological benefits. The key is to find a form/style of fasting that works for you and which yields the results you want. No matter what you do, it requires [what may be] a whole new level of paying attention to your body; how you feel, how much you weigh, how strong you feel, how sharp your mind seems, etc. IF is putting your food consumption and internal eating-related systems on manual. That can be great, or it can be a car crash.

I’ve come to realize that the style of fasting I do is not actually me “doing something”, but rather me living in tune with my body. The way I ate previously was automated and not healthy. I started IF as a project, and now it’s simply more normal and healthy than they way I used to eat.

That photo? In the “before” photo (the left half) I am the unrecognizable person on the right. :)

Recently a friend of mine emailed me and asked, “Hey Craig, tell me about that diet you went on a few years ago.” He was referring to what I did from ~2008 to ~2016—the photos above were taken in 2008 and 2016. Below is my response and this just happens to all coincide with the “ten year challenge” currently all over social media.

Beyond vanity, the reported health effects of an intelligently designed Intermittent Fasting program read like a laundry list of live longer, live better benefits including: reduced blood lipids, blood pressure, markers of inflammation, oxidative stress, and cancer. Increased cell turnover and repair, fat burning, growth hormone release, and metabolic rate. And improved appetite control, blood sugar control, cardiovascular function, and neuronal plasticity.

How often should we eat? →

When I started experimenting with intermittent fasting a year or so ago, it occurred to me that my previous beliefs about our ‘need’ to eat three times a day were just wide of the mark for me and, as it turns out, a lot of other people now. I now encourage a much more fluid approach based on the two guidelines above. One thing it’s done for me and others is to liberate us from the supposed need to eat by the clock. The benefits can be huge. In general, taking a more fluid approach seems to lead to people eating less, having more time, and being less preoccupied with food. These are usually big pluses for people.

Study suggests that, for optimal fat loss, the best thing to eat before exercise is nothing at all →

The concept of endurance athletes stocking up on carbs has, I think, fuelled the notion that we should ideally have some sort of fuel inside of us prior to exercise. However, as I explain here, there is an argument for avoiding spikes in blood sugar is seeking to maximise one’s capacity to utilise fat as a fuel during exercise. I think there’s an argument for consuming little or nothing before exercise unless, perhaps, exercise is to be very prolonged.

Sometimes people don’t believe me when, around 11am in the middle of some crazy physical activity, it comes up that I haven’t yet eaten anything. I usually ask them why they think they must eat every waking hour? Why is “breakfast the most important meal of the day”? Why do you eat what you generally eat? And then I ask them to consider looking into the notions they have about nutrition…
