Shedding Some Obesity Myths

Let’s shed some obesity myths!
There are a lot of myths and misconceptions surrounding obesity… And then there are also reactive opposite myths and misconceptions, which can sometimes be just as harmful!
To tackle them all would take a book, but in classic 10almonds style, we’re going to put a spotlight on some of the ones that might make the biggest difference:
True or False: Obesity is genetically pre-determined
False… With caveats.
Some interesting results have been found from twin studies and adoption studies, showing that genes definitely play some role, but lifestyle is—for most people—the biggest factor:
- The body-mass index of twins who have been reared apart
- An adoption study of human obesity
- Using a sibling-adoption design to parse genetic and environmental influences on children’s body mass index
In short: genes predispose; they don’t predetermine. But that predisposition alone can make quite a big difference, if it in turn leads to different lifestyle factors.
But upon seeing those papers centering BMI, let’s consider…
True or False: BMI is a good, accurate measure of health in the context of bodyweight
False… Unless you’re a very large group of thin white men of moderate height, which was the demographic the system was built around.
Bonus information: it was never intended to be used to measure the weight-related health of any individual (not even an individual thin white man of moderate height), but rather, as a tool to look at large-scale demographic trends.
Basically, as a system, it’s being used in a way it was never made for, and the results of that misappropriation of an epidemiological tool for individual health are predictably unhelpful.
To do a deep-dive into all the flaws of the BMI system, which are many, we’d need to devote a whole main feature just to that.
Update: we have now done so!
Here it is: When BMI Doesn’t Measure Up
True or False: Obesity does not meaningfully impact more general health
False… In more ways than one (but there are caveats)
Obesity is highly correlated with increased risk of all-cause mortality, and weight loss, correspondingly, correlates with a reduced risk. See for example:
So what are the caveats?
Let’s put it this way: owning a horse is highly correlated with increased healthy longevity. And while owning a horse may come with some exercise and relaxation (both of which are good for the health), it’s probably mostly not the horse itself that conveys the health benefits… it’s that someone who has the resources to look after a horse, probably has the resources to look after their own health too.
So sometimes there can be a reason for a correlation (it’s not a coincidence!) but the causative factor is partially (or in some cases, entirely) something else.
So how could this play out with obesity?
There’s a lot of discrimination in healthcare settings, unfortunately! In this case, it often happens that a thin person goes in with a medical problem and gets treated for that, while a fat person can go in with the same medical problem and be told “you should try losing some weight”.
Top tip if this happens to you… Ask: “what would you advise/prescribe to a thin person with my same symptoms?”
Other things may be more systemic, for example:
When a thin person goes to get their blood pressure taken, and that goes smoothly, while a fat person goes to get their blood pressure taken, and there’s not a blood pressure cuff to fit them, is the problem the size of the person or the size of the cuff? It all depends on perspective, in a world built around thin people.
That’s a trivial-seeming example, but the same principle has far-reaching (and harmful) implications in healthcare in general, e.g:
- Surgeons being untrained (and/or unwilling) to operate on fat people
- Getting a one-size-fits-all dose that was calculated using average weight, and now doesn’t work
- MRI machines are famously claustrophobia-inducing for thin people; now try not fitting in it in the first place
…and so forth. So oftentimes, obesity will be correlated with a poor healthcare outcome, where the problem is not actually the obesity itself, but rather the system having been set up with thin people in mind.
It would be like saying “Having O- blood type results in higher risks when receiving blood transfusions”, while omitting to add “…because we didn’t stock O- blood”.
True or False: to reduce obesity, just eat less and move more!
False… Mostly.
Moving more is almost always good for most people. When it comes to diet, quality is much more important than quantity. But these factors alone are only part of the picture!
But beyond diet and exercise, there are many other implicated factors in weight gain, weight maintenance, and weight loss, including but not limited to:
- Disrupted sleep
- Chronic stress
- Chronic pain
- Hormonal imbalances
- Physical disabilities that preclude a lot of exercise
- Mental health issues that add (and compound) extra levels of challenge
- Medications that throw all kinds of spanners into the works with their side effects
…and even just those first two things, diet and exercise, are not always so correlated to weight as one might think—studies have found that the difference for exercise especially is often marginal:

The Age-Proof Brain – by Dr. Marc Milstein
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Biological aging is not truly just one thing, but rather the amalgam of many things intersecting—and most of them are modifiable. The cells of your body neither know nor care how many times you have flown around the sun; they just respond to the stimuli they’re given.
Which is what fuels this book. The idea is to have a brain that is less-assailed by the things that would make it age, and more rejuvenated by the things that can make it biologically younger.
Dr. Milstein doesn’t neglect the rest of the body, and indeed notes the brain’s connections with the immune system, the heart, the gut, and more. But everything in this book is done with the brain in mind and its good health as the top priority outcome of all the things he advises.
On which note, yes, there is plenty of practical, implementable advice here. For a book that is consistently full of study paper citations, he does take care to make everything useful to the reader, and makes everything as easy as possible for the layperson along the way.
Bottom line: if you would like your brain to age less, this is an excellent, very evidence-based, guidebook.

Policosanol: A Rival To Statins, Without The Side Effects?
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Policosanol (which can be extracted from various sources, but is mostly made from sugar cane extract) is marketed as lipid-lowering agent for improving cholesterol levels, but its research history has not been without controversy:
2001: it works!
After a lot of research in the 1990s, it came out of the gate strong in 2001, with:
❝Policosanol (5 and 10 mg/day) significantly decreased LDL-cholesterol (17.3% and 26.7%, respectively), total cholesterol (12.9% and 19.5%), as well as the ratios of LDL-cholesterol to high-density lipoprotein (HDL)-cholesterol (17.2% and 26.5%) and total cholesterol to HDL-cholesterol (16.3% and 21.0%) compared with baseline and placebo❞
This, by the way, is comparable in efficacy to the most powerful statins, but without the adverse side effects.
Source: Efficacy and tolerability of policosanol in hypercholesterolemic postmenopausal women
Furthermore, its effects were not limited to postmenopausal women, and additionally, it was found that 20mg/day was sufficient for optimal effects; 40mg worked exactly the same as 20mg:
2006–2010: we do not trust the Cubans!
After it had been marketed and used in much of the world for some years, extra scrutiny was brought upon it, because the initial studies had been performed by the same lab in Cuba, a commercial lab that had tested them for a private interest (i.e., a company selling the supplement):
Heart Beat: Policosanol: A sweet nothing for high cholesterol
And furthermore, US-based labs were unable to replicate the results:
Policosanols as Nutraceuticals: Fact or Fiction
The Cuban researchers countered that the composition of policosanol as produced in their lab was different than the composition of the policosanol as produced in the US labs, because of the purity of the ingredients used in the Cuban lab.
Which, on the face of it, could be true or could just be the claim of a commercial lab with an association with a company selling a product.
Of course, importing Cuban ingredients to test them in the US was not a reasonably accessible option for the US-based labs, because of the US’s embargo of Cuba. In principle it could be done, but unless there is already a huge clear profit incentive, research scientists are usually on their hands and knees begging for grants already, so getting extra funding for specially-important Cuban ingredients was not going to be likely.
2012: never mind, it does work after all!
An American meta-analysis of 4596 patients from 52 eligible studies (from around the world, so many of them not affected by the US’s embargo; some were from within the US using non-Cuban ingredients, though), found:
❝policosanol is more effective than plant sterols and stanols for LDL level reduction and more favorably alters the lipid profile, approaching antilipemic drug efficacy❞
Those last words there, to be clear, mean “yes, the original claim of being on a par with statins is at least more or less true”.
Source: Meta-Analysis of Natural Therapies for Hyperlipidemia: Plant Sterols and Stanols versus Policosanol
2018: also yes, the Cuban kind does get those extra-effective results, even when tested outside of Cuba
A Korean research team verified this; it’s quite straightforward so for brevity we’ll just drop links:
- Consumption of Cuban Policosanol Improves Blood Pressure and Lipid Profile via Enhancement of HDL Functionality in Healthy Women Subjects: Randomized, Double-Blinded, and Placebo-Controlled Study
- Long-Term Consumption of Cuban Policosanol Lowers Central and Brachial Blood Pressure and Improves Lipid Profile With Enhancement of Lipoprotein Properties in Healthy Korean Participants
Mystery resolved!
Want to try some?
We don’t sell it, but here for your convenience is an example product on Amazon—it’s not the Cuban kind, because the US’s trade embargo makes it difficult for the US to import even things that are theoretically now exempt from the embargo such as food and medicines. In principle they can now be imported, but in practice, the extra regulations added to Cuban imports make it nearly impossible, especially for small sellers.
Still, it’s 40mg/tablet policosanol from sugar cane extract, and 3rd party lab tested, so it’s the next best thing 😎
Enjoy!

Undoing The Damage Of Life’s Hard Knocks

Sometimes, What Doesn’t Kill Us Makes Us Insecure
We’ve written before about Complex PTSD, which is much more common than the more popularly understood kind:
Given that C-PTSD affects so many people (around 1 in 5, but really, do read the article above! It explains it better than we have room to repeat today), it seems like a good idea to share tips for managing it.
(Last time, we took all the space for explaining it, so we just linked to some external resources at the end)
What happened to you?
PTSD has (as a necessity, as part of its diagnostic criteria) a clear event that caused it, which makes the above question easy to answer.
C-PTSD often takes more examination to figure out what tapestry of circumstances (and likely but not necessarily: treatment by other people) caused it.
Often it will feel like “but it can’t be that; that’s not that bad”, or “everyone has things like that” (in which case, you’re probably one of the one in five).
The deeper questions
Start by asking yourself: what are you most afraid of, and why? What are you most ashamed of? What do you fear that other people might say about you?
Often there is a core pattern of insecurity that can be summed up in a simple, harmful, I-message, e.g:
- I am a bad person
- I am unloveable
- I am a fake
- I am easy to hurt
- I cannot keep my loved ones safe
…and so forth.
For a bigger list of common insecurities to see what resonates, check out:
Basic Fears/Insecurities, And Their Corresponding Needs/Desires
Find where they came from
You probably learned bad beliefs, and consequently bad coping strategies, because of bad circumstances, and/or bad advice.
- When a parent exclaimed in anger about how stupid you are
- When a partner exclaimed in frustration that always mess everything up
- When an employer told you you weren’t good enough
…or maybe they told you one thing, and showed you the opposite. Or maybe it was entirely non-verbal circumstances:
- When you gambled on a good idea and lost everything
- When you tried so hard at some important endeavour and failed
- When you thought someone could be trusted, and learned the hard way that you were wrong
These are “life’s difficult bits”, but when we’ve lived through a whole stack of them, it’s less like a single shattering hammer-blow of PTSD, and more like the consistent non-stop tap tap tap that ends up doing just as much damage in the long run.
Resolve them
That may sound a bit like a “and quickly create world peace” level of task, but we have tools:
Ask yourself: what if…
…it had been different? Take some time and indulge in a full-blown fantasy of a life that was better. Explore it. How would those different life lessons, different messages, have impacted who you are, your personality, your behaviour?
This is useful, because the brain is famously bad at telling real memories from false ones. Consciously, you’ll know that one was an exploratory fantasy, but to your brain, it’s still doing the appropriate rewiring. So, little by little, neuroplasticity will do its thing.
Tell yourself a better lie
We borrowed this one from the title of a very good book which we’ve reviewed previously.
This idea is not about self-delusion, but rather that we already express our own experiences as a sort of narrative, and that narrative tends to contain value judgements that are often not useful, e.g. “I am stupid”, “I am useless”, and all the other insecurities we mentioned earlier. Some simple examples might be:
- “I had a terrible childhood” → “I have come so far”
- “I should have known better” → “I am wiser now”
- “I have lost so much” → “I have experienced so much”
So, replacing that self-talk can go a long way to re-writing how secure we feel, and therefore how much trauma-response (ideally: none!) we have to stimuli that are not really as threatening as we sometimes feel they are (a hallmark of PTSD in general).
Here’s a guide to more ways:

Never Enough – by Dr. Judith Grisel
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
We’ve reviewed books about addiction before—specifically about alcohol, at least. This one’s more general in that it covers different addictions.
On the other hand, it’s also more specific, in that it covers them from the author’s field: neuroscience.
…and experience too. The author had a plethora of addictions (the serious kind), got sober, and then undertook to study neuroscience. Her hope was to help others avoid, or escape from the same as‚ what she went through.
Dr. Grisel (as she now is) takes a methodical approach in this book. She works her way through the addictive mechanisms of a broad selection of common drugs, explaining each.
The focus here is on neutral explanations, rather than the propagandizing scaremongering that failed at least one generation. Why each drug is alluring, what it really does do—and the neurological price it exacts, down to the molecular level.
She also covers risk factors for addiction; genetic, epigenetic, and environmental. There’s no “if you were stronger”, or “these people made bad choices”, so much as… Many addicts were, in effect, sabotaged from before birth.
That doesn’t mean that to become addicted or not is just fate, but it does mean… There but for the grace of factors completely outside of our control go we.
Why is this useful to us, be we a reader without any meaningful addiction (we’re not counting coffee etc here)? Well, as this book illustrates and explains, many of us could be one (more) mishap away from a crippling addiction and not know it. Forewarned is forearmed.
Bottom line: almost all of us are, have been, or will be touched by addiction in some way. Either directly, or a loved one, or a loved one’s loved one, or perhaps a parent who gave us an epigenetic misfortune. This book gives understanding that can help.

The Mindful Body – by Dr. Ellen Langer
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Fear not, this is not a “think healing thoughts” New Age sort of book. In fact, it’s quite the contrary.
The most common negative reviews for this on Amazon are that it is too densely packed with scientific studies, and some readers found it hard to get through since they didn’t find it “light reading”.
Counterpoint: this reviewer found it very readable. A lot of it is as accessible as 10almonds content, and a lot is perhaps halfway between 10almonds content in readability, and the studies we cite. So if you’re at least somewhat comfortable reading academic literature, you should be fine.
The author, a professor of psychology (tenured at Harvard since 1981), examines a lot of psychosomatic effect. Psychosomatic effect is often dismissed as “it’s all in your head”, but it means: what’s in your head has an effect on your body, because your brain talks to the rest of the body and directs bodily responses and actions/reactions.
An obvious presentation of this in medicine is the placebo/nocebo effect, but Dr. Langer’s studies (indeed, many of the studies she cites are her own, from over the course of her 40-year career) take it further and deeper, including her famous “Counterclockwise” study in which many physiological markers of aging were changed (made younger) by changing the environment that people spent time in, to resemble their youth, and giving them instructions to act accordingly while there.
In the category of subjective criticism: the book is not exceptionally well-organized, but if you read for example a chapter a day, you’ll get all the ideas just fine.
Bottom line: if you want a straightforward hand-holding “how-to” guide, this isn’t it. But it is very much information-packed with a lot of ideas and high-quality science that’s easily applicable to any of us.

The Obesity Code – by Dr. Jason Fung
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Firstly, if you have already read Dr. Fung’s other book, The Diabetes Code, which we reviewed a little while ago, you can probably skip this one. It has mostly the same information, presented with a different focus.
While The Diabetes Code assumes you are diabetic, or prediabetic, or concerned about avoiding/reversing those conditions, The Obesity Code assumes you are obese, or heading in that direction, or otherwise are concerned about avoiding/reversing obesity.
What it’s not, though, is a weight loss book. Will it help if you want to lose weight? Yes, absolutely. But there is no talk here of weight loss goals, nor any motivational coaching, nor week-by-week plans, etc.
Instead, it’s more an informative textbook. With exactly the sort of philosophy we like here at 10almonds: putting information into people’s hands, so everyone can make the best decisions for themselves, rather than blindly following someone else’s program.
Dr. Fung explains why various dieting approaches don’t work, and how we can work around such things as our genetics, as well as most external factors except for poverty. He also talks us through how to change our body’s insulin response, and get our body working more like a lean machine and less like a larder for hard times.
Bottom line: this is a no-frills explanation of why your body does what it does when it comes to fat storage, and how to make it behave differently about that.
