Steps For Keeping Your Feet A Healthy Foundation

Important Steps For Good Health
This is Dr. Kelly Starrett. He’s a physiotherapist, author, speaker, trainer. He has been described as a “celebrity” and “founding father” of CrossFit. He mostly speaks and writes about mobility in general; today we’re going to be looking at what he has to say specifically about our feet.
A strong foundation
“An army marches on its stomach”, Napoleon famously wrote.
More prosaically: an army marches on its feet, and good foot-care is a top priority for soldiers—indeed, in some militaries, even so much as negligently getting blisters is a military offense.
Most of us are not soldiers, but there’s a lesson to be learned here:
Your feet are the foundation for much of the rest of your health and effectiveness.
KISS for feet
No, not like that.
Rather: “Keep It Simple, Stupid”
Dr. Starrett is not only a big fan of not overcomplicating things, but also, he tells us how overcomplicating things can actively cause problems. When it comes to footwear, for example, he advises:
❝When you wear shoes, wear the flat kind. If you’re walking the red carpet on Oscar night, fine, go ahead and wear a shoe with a heel. Once in a while is okay.
But most of the time, you should wear shoes that are flat and won’t throw your biological movement hardware into disarray.
When you have to wear shoes, whether it’s running shoes, work shoes, or combat boots, buy the flat kind, also known as “zero drop”—meaning that the heel is not raised above the forefoot (at all).
What you want to avoid, or wean yourself away from, are shoes with the heels raised higher off the ground than the forefeet.❞
Of course, going barefoot is great for this, but may not be an option for all of us when out and about. And in the home, going barefoot (or shod in just socks) will only confer health benefits if we’re actually on our feet! So… How much time do you spend on your feet at home?
Allow your feet to move like feet
By evolution, the human body is built for movement—especially walking and running. That came with moving away from hanging around in trees for fruit, to hunting and gathering between different areas of the savannah. Today, our hunting and gathering may be done at the local grocery store, but we still need to keep our mobility, especially when it comes to our feet.
Now comes the flat footwear you don’t want: flip-flops and similar
If we wear flip-flops, or other slippers or shoes that hold onto our feet only at the front, we’re no longer walking like we’re supposed to. Instead of being the elegant product of so much evolution, we’re now walking like those AT-AT walkers in Star Wars, you know, the ones that fell over so easily?
Our feet need to be able to tilt naturally while walking/running, without our footwear coming off.
Golden rule for this: if you can’t run in them, you shouldn’t be walking in them
Exception: if for example you need something on your feet for a minute or two in the shower at the gym/pool, flip-flops are fine. But anything more than that, and you want something better.
Watch your step
There’s a lot here that’s beyond the scope of what we can include in this short newsletter, but:
If we stand or walk or run incorrectly, we’re doing gradual continual damage to our feet and ankles (potentially also our knees and hips, which problems in turn have a knock-on effect for our spine, and you get the idea—this is Bad™)
Some general pointers for keeping things in good order include:
- Your weight should be mostly on the balls of your feet, not your heels
- Your feet should be pretty much parallel, not turned out or in
- When standing, your center of gravity should be balanced between heel and forefoot
Quick tip for accomplishing this last one: Stand comfortably, your feet parallel, shoulder-width apart. Now, go up on your tip-toes. When you’ve done so, note where your spine is, and keep it there (apart from in its up-down axis) when you slowly go back to having your feet flat on the ground, so it’s as though your spine is sliding down a pole that’s fixed in place.
If you do this right, your center of gravity will now be perfectly aligned with where it’s supposed to be. It might feel a bit weird at first, but you’ll get used to it, and can always reset it whenever you want/need, by repeating the exercise.

The Biological Mind – by Dr. Alan Jasanoff
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.
How special is our brain? According to Dr. Alan Jasanoff, it’s not nearly as special as we think it is.
In this work, he outlines the case for how we have collectively overstated the brain’s importance. That it’s just another organ like a heart or a kidney, and that who we are is as much a matter of other factors, as what goes on in our brain.
In this reviewer’s opinion, he overcorrects a bit. The heart and kidneys are very simple organs, as organs go. The brain is not. And while everything from our gut microbiota to our environment to our hormones may indeed contribute to what is us, our brain is one thing that can’t just be swapped out.
Nevertheless, this very well-written book can teach us a lot about everything else that makes us us, including many biological factors that many people don’t know about or consider.
Towards the end of the book, he switches into futurist speculation, and his speculation can be summed up as “we cannot achieve anything worthwhile in the future”.
Bottom line: if you’ve an interest in such things as how transplanting glial cells can give a 30% cognitive enhancement, and how a brain transplant wouldn’t result in the same us in a different body, this is the book for you.

The Circadian Code – by Dr. Satchin Panda
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.
There’s a lot more to circadian rhythm than “sleep during these hours”. And there’s a lot more to bear in mind than “don’t have blue/white light at night”.
In fact, Dr. Satchin Panda explains, there’s a whole daily symphony of movements in our body as different biochemical processes wax and wane according to what time of day it is.
There are several important things he wants us to know about this:
- Our body needs to know what time it is, for those processes to work correctly
- Because of these daily peaks and troughs of various physiological functions, we get “correct” times for things we do every day. Not just sleeping/waking, but also:
- The best time to eat
- The best time to exercise
- The best time to do mental work
- The best times to take different kinds of supplements/medications
Dr. Panda also looks at what things empower, or disempower, our body to keep track of what time it is.
Bottom line: if you’d like to optimize your days and your health, this book has a lot of very valuable practicable tips.

Hack Your Hunger
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.
When it comes to dealing with hunger, a common-sense way of dealing with it is “eat something”. However, many people find that they then eat the wrong things, in the wrong quantities, and end up in a cycle of overeating and being hungry.
If this gets to the extreme, it can turn into a full-blown eating disorder:
Eating Disorders: More Varied (And Prevalent) Than People Think
…and even in more moderate presentations, the cycle of hunger and overeating is not great for the health. So, how to avoid that?
Listen to your body (but: actually listen)
Your body says: we’re running a little low on glycogen reserves so our energy’s going to start suffering in a few hours if we don’t eat some fruit, kill something and eat its fatty organs, or perhaps find some oily nuts.
You hear: eat something bright and sugary, shout at the dog, eat some fried food, got it!
Your body says: our water balance is a little off, we could do with some sodium, potassium, and perhaps some phosphorus to correct it.
You hear: eat something salty, got it, potato chips coming right up!
…and so on. Now, we know 10almonds readers are quite a health-conscious readership, so perhaps your responses are not quite like that. But the take-away point is still important: we need to listen to the whole message, and give the body what it actually needs, not what will just shut the message off the most quickly.
Here’s how: Intuitive Eating Might Not Be What You Think
Bonus: Interoception: Improving Our Awareness Of Body Cues
About those cravings…
As illustrated a little above, a lot of cravings might not be what they first appear, and in evolutionary terms, our body is centuries behind industrialization, in terms of adaptations, which means that even if we try to take the above into account, our responses can sometimes be inappropriate in the age of supermarkets.

Natural appetite suppressants
Eating more is not always the answer, not even if it’s more healthy food. And hunger pangs can be especially inconvenient if, for example, we are fasting at present, which is by the way a very healthful thing for most people:
Learn more: Intermittent Fasting: What’s the truth?
One way to suppress hunger is simply to trigger the stomach into sending “full” signals, which involves filling it. Since you do not want to overeat, the trick here is imply to use high-volume food.
Consider for example: 30 grapes and 30 raisins have approximately the same calorie count (what with raisins being dried grapes, and the calories didn’t evaporate), but the bowl of fresh fruit is going to physically fill your stomach a lot more quickly than the tiny amount of dried fruit.
More on this: Some Surprising Truths About Hunger And Satiety
Protein is of course also an appetite suppressant, but it takes about 20 minutes for the signal to kick in. So a “hack” here is to snack on something proteinous at least 15 minutes before your main meal (for example, a portion of nuts while cooking, unless you’re allergic, or some dried fish unless you’re vegetarian/vegan; you get it, pick something high in protein and good for snacking, and have a small portion before your main meal).
Nor is protein the only option!

Scale it down
Related to the above, there is a feedback loop that occurs here. The more you eat, the more your stomach slowly grows to accommodate it; the less you eat, the more your stomach slowly shrinks because the body tries hard to be an efficient organism, and will not maintain something that isn’t being used.
So, there’s a bit of a catch-22; sate your hunger by filling your stomach with high volume foods, but filling it will cause it to grow?
The trick is: do the “eat until 80% full” thing. That’s full enough that you have had a nice meal and are not suffering, without stretching the stomach.
Enjoy your food
Seriously! Actually enjoy it. Which means paying full attention to it. Eating can and should be a wonderful experience, so it’s best savored rather than inhaling a bowl of something in 30 seconds.
Have you seen those dog bowls that have obstructions to slow down how quickly a dog eats? We can leverage that kind of trick too! While you might not want to eat from a dog bowl, how about having a little bowl of pistachio nuts rather than ready-to-eat peanuts? Or any shelled nuts that we must shell as we go. If you’re allergic to nuts, there are plenty of other foods with a high work-to-food ratio. Take some time and enjoy that pomegranate, for instance!
Not that we necessarily have to make things difficult for ourselves either; we can just take appropriate care to ensure a good dining experience. Life is for living, so why not enjoy it?

Beat The Heat, With Fat
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.
Surviving Summer
Summer is upon us, for those of us in the Northern Hemisphere anyway, and given that nowadays each year tends to be hotter than the one before, on average, it pays to be prepared.
We’ve talked about dealing with the heat before:
Sun, Sea, And Sudden Killers To Avoid
All the above advice stands this summer too, but today we’re going to speak a little extra on not having a “default body”.
For much of medical literature and common health advice, the default body is that of a slim and/or athletic white cis man aged 25–35 with no disabilities.
When it comes to “women’s health”, this is often confined to “the bikini zone” and everything else is commonly treated based on research conducted with men.
Today we’ll be looking at a particular challenge for a wide variety of people, when it comes to heat…
Beating the heat, with fat
If you are fat, and/or have a bit of a tummy, and/or have breasts, this one’s for you.
Fat acts as an insulator, which naturally does no favors in hot weather. Carrying the weight around is also extra exercise, which also becomes a problem in hot weather. Fat people usually sweat more than thin people do, as a result.
Sweat is great for cooling down the body, because it takes heat with it when it evaporates off. However, that only works if it can evaporate off, and it can’t evaporate off if it’s trapped in a skin fold / fat roll.
If you’re fat, you may have plenty of those; if you have a bit of a tummy (if you’re not fat generally, this might be a leftover from pregnancy, or weight loss, or something else; how it got there doesn’t matter for our purposes today), you’ll have at least one under it, and if you have breasts, unless they’re quite small, you’ll have one under each breast, and potentially your cleavage may become an issue too.
Note: if you are perhaps a man who has fat in the place where breasts go, then medically this goes for you too, except that there’s not a societal expectation that you wear bra. Use today’s information as you see fit.
Sweat-wicking hacks
We don’t want sweat to stay in those folds—both because then it’s not doing its cooling-down job, and also, because it can cause a rash, and even yeast infections and/or bacterial infections.
So, we want there to be some barrier there. You could use something like vaseline or baby powder, as to prevent chafing, but fat better (more effective, and less messy) is to have some kind of cloth there that can wick the sweat away.
There are made-for-purpose curved cotton bands that exist, called “tummy liners”; here’s an example product on Amazon, or you could make your own if you’re so inclined. They’re breathable, absorbent, and reduce friction too, making everything a lot more comfortable.
And for breasts? Same deal, there are made-for-purpose cotton bra-liners that exist; here’s an example product on Amazon, or again, you could make your own if you feel so inclined. The important part is that it makes things so much comfortable, because let’s face it: wearing a bra in the summer is not comfortable.
So with these, it can become more comfortable (and the cotton liners are flat, so they’re not visible if one’s wearing a t-shirt or similar-coverage garment). You could go braless, of course, but then you’re back to having sweaty folds, so if you’re doing something other than swimming or lying on your back, you might want something there.
Different hydration rules
“People should drink this much per day” and guess what, those guidelines were based on, drumroll please, not fat people.
Sweating more means needing to hydrate more, and even without breaking a sweat, having a larger body than average (be it muscle, fat, or both) means having more body to hydrate. That’s simple math.
So instead, a good general guideline is half an ounce of water per your weight in pounds, per day:
How much water do I need each day?
Another good general guideline is to simply drink “little and often”, that is to say, always have a (hydrating!) drink on the go.
Take care!

Chocolate & Health
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.
Chocolate & Health: Fact or Fiction?
“Chocolate Is Good For The Heart”
“When making chocolate chip cookies, you don’t measure using cups, you measure by heart”
…but how good is chocolate when it comes to heart health?
First, what is heart health?
A healthy heart typically has a low resting pulse rate and a strong, steady beat. This is affected strongly by exercise habits, and diet plays only a support role (can’t exercise without energy from food!).
It is also important to have blood pressure within a healthy range (with high blood pressure being a more common problem than low, so things that lower blood pressure are generally considered good).
- Flavanols, flavonoids, and polyphenols in chocolate contribute to lower blood pressure
- Dark chocolate is best for these, as milk chocolate contains much less cocoa solids and more unhelpful fats
- White chocolate contains no cocoa solids and is useless for this
- Some of the fats in most commercial chocolate can contribute to atherosclerosis which raises blood pressure and ultimately can cause heart attacks.
- If you’re diabetic, you will probably not get the usual heart-related benefits from chocolate (sorry)
The Verdict: dark chocolate, in moderation, can support good heart health.
“Chocolate Is Good For The Brain”
Chocolate has been considered a “brain food”… why?
- The brain uses more calories than any other organ (chocolate has many calories)
- The heart benefits we listed above mean improved blood flow—including to your brain
- Chocolate contains phenylethylamine, a powerful chemical that has a similar effect to amphetamines… But it’s metabolized in digestion and never makes it to the central nervous system (so basically, this one’s a miss; we had a good run with the other two, though!)
The Verdict: dark chocolate, in moderation, can support good brain health
“Chocolate Is An Aphrodisiac”
“If chocolate be the food of love, pass me that cocoa; I’m starving”
Most excitingly, chocolate contains phenylethylamine, the “molecule of love” or, more accurately, lust. It has an effect similar to amphetamines, and while we can synthesize it in the body, we can also get it from certain foods. But…
Our body is so keen to get it that most of it is metabolized directly during digestion and doesn’t make it to the brain. Also, chocolate is not as good a source as cabbage—do with that information what you will!
However!
Chocolate contains theobromine and small amounts of caffeine, both stimulants and both generally likely to improve mood; it also contains flavonoids which in turn stimulate production of nitric oxide, which is a relaxant. All in all, things that are convivial to having a good time.
On the other hand…
That relaxation comes specifically with a reduction in blood pressure—something typically considered good for the health for most people most of the time… but that means lowering blood pressure in all parts of your body, which could be the opposite of what you want in intimate moments.
Chocolate also contains zinc, which is essential for hormonal health for most people—the body uses it to produce testosterone and estrogen, respectively. Zinc supplements are popularly sold to those wishing to have more energy in general and good hormonal health in particular, and rightly so. However…
This approach requires long-term supplementation—you can’t just pop a zinc tablet / bar of chocolate / almond before bed and expect immediate results. And if your daily zinc supplementation takes the form of a 3.5oz (100g) bar of chocolate, then you may find it has more effects on your health, and not all of them good!
The Verdict: dark chocolate, in moderation, may promote “the mood”, but could be a double-edged sword when it comes to “the ability”.
“Chocolate Is Good During Menstruation”
The popular wisdom goes that chocolate is rich in iron (of which more is needed during menstruation), and indeed, if you eat 7oz (150g) of dark chocolate made with 85% cocoa, you’ll get a daily a dose of iron (…and nearly 1,000 calories).
More bang-for-buck dietary sources of iron include chickpeas and broccoli, but for some mysterious reason, these are not as commonly reported as popular cravings.
The real explanation for chocolate cravings is more likely that eating chocolate—a food high in sugar and fat along with a chemical bombardment of more specialized “hey, it’s OK, you can relax now” molecules (flavanols/flavonoids, polyphenols, phenylamines, even phenylethylamine, etc) gives a simultaneous dopamine kick (the body’s main “reward” chemical) with a whole-body physiological relaxation… so, little wonder we might crave it in times of stress and discomfort!
The Verdict: it helps, not because it serves a special nutritional purpose, but rather, because the experience of eating chocolate makes us feel good.
Fun fact: Tiramisu (this writer’s favorite dessert) is literally Italian for “pick-me-up”
