We’ve all heard that “sitting is the new smoking”, and whether or not that’s an exaggeration (the jury’s out), one thing that is clear is that sitting is very bad.
Popular advice is “here’s how to sit with good posture and stretch your neck sometimes”… but that advice tends to come from companies that pay people to sit for a long time. They might not be the a very unbiased source.
Starrett and Cordoza offer better. After one opening chapter covering the multifarious ways sitting ruins our health, the rest of the book is all advice, covering:
- The principles of how the body is supposed to be
- The most important movements that we should be doing
- A dynamic workstation setup
- This is great, because “get a standing desk” tends to present more questions than answers, and can cause as much harm as good if done wrong
- The authors also cover how to progressively cut down on sitting, rather than try to go cold-turkey.
- They also recognize that not everyone can stand at all, and…
- Optimizing the sitting position, for when we must sit
- Exercises to maintain our general mobility and compensate about as well as we can for the body-unfriendly nature of modern life.
The book is mostly explanations, so at 682 pages, you can imagine it’s not just “get up, lazybones!”. Rather, things are explained in such detail (and with many high-quality medical diagrams) so that we can truly understand them.
Most of us have gone through life knowing we should have “better posture” and “move more”… but without the details, that can be hard to execute correctly, and worse, we can even sabotage our bodies unknowingly with incorrect form.
This book straightens all that out very comprehensively, and we highly recommend it.

What Does “Balance Your Hormones” Even Mean?
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.
Hormonal Health: Is It Really A Balancing Act?
Have you ever wondered what “balancing your hormones” actually means?
The popular view is that men’s hormones look like this:
Testosterone (less) ⟷ Testosterone (more)
…And that women’s hormones look more like this:
♀︎ Estrogen ↭ Progesterone ⤵︎
⇣⤷ FSH ⤦ ↴ ☾ ⤹⤷ Luteinizing Hormone ⤦
DHEA ↪︎ Gonadotrophin ⤾
↪︎ Testosterone? ⥅⛢
Clear as mud, right?
But, don’t worry, Supplements McHerbal Inc will sell you something guaranteed to balance your hormones!
How can a supplement (or dietary adjustment) “balance” all that hotly dynamic chaos, and make everything “balanced”?
The truth is, “balanced” in such a nebulous term, and this is why you will not hear endocrinologists using it. It’s used in advertising to mean “in good order”, and “not causing problems”, and “healthy”.
In reality, our hormone levels depend on everything from our diet to our age to our anatomy to our mood to the time of the day to the phase of the moon.
Not that the moon has an influence on our physiology at all—that’s a myth—but you know, 28 day cycle and all. And, yes, half the hormones affect the levels of the others, either directly or indirectly.
Trying to “balance” them would be quite a game of whack-a-mole, and not something that a “cure-all” single “hormone-balancing” supplement could do.
So why aren’t we running this piece on Friday, for our “mythbusting” section? Well, we could have, but the more useful information is yet to come and will take up more of today’s newsletter than the myth-busting!
What, then, can we do to untangle the confusion of these hormones?
Well first, let’s understand what they do, in the most simple terms possible:
- Estrogen—the most general feminizing hormone from puberty onwards, busiest in the beginning of the menstrual cycle, and starts getting things ready for ovulation.
- Progesterone—secondary feminizing hormone, fluffs the pillows for the oncoming fertilized egg to be implanted, increases sex drive, and adjusts metabolism accordingly. Busiest in the second half of the menstrual cycle.
- Testosterone—is also present, contributes to sex drive, is often higher in individuals with PCOS. If menopause is untreated, testosterone will also rise, because there will be less estrogen
- (testosterone and estrogen “antagonize” each other, which is the colorfully scientific way of saying they work against each other)
- DHEA—Dehydroepiandrosterone, supports production of testosterone (and estrogen!). Sounds self-balancing, but in practice, too much DHEA can thus cause elevated testosterone levels, and thus hirsutism.
- Gonadotrophin—or more specifically human chorionic gonadotrophin, HcG, is “the pregnancy hormone“, present only during pregnancy, and has specific duties relating to such. This is what’s detected in (most) pregnancy test kits.
- FSH—follicle stimulating hormone, is critical to ovulation, and is thus essential to female fertility. On the other hand, when the ovaries stop working, FSH levels will rise in a vain attempt to encourage the ovulation that isn’t going to happen anymore.
- Luteinizing hormone—says “go” to the new egg and sends it on its merry way to go get fertilized. This is what’s detected by ovulation prediction kits.
Sooooooo…
What, for most women, most often is meant by a “hormonal imbalance” is:
- Low levels of E and/or P
- High levels of DHEA and/or T
- Low or High levels of FSH
In the case of low levels of E and/or P, the most reliable way to increase these is, drumroll please… To take E and/or P. That’s it, that’s the magic bullet.
Bonus Tip: take your E in the morning (this is when your body will normally make more and use more) take your P in the evening (it won’t make you sleepy, but it will improve your sleep quality when you do sleep)
In the case of high levels of DHEA and/or T, then that’s a bit more complex:
- Taking E will antagonize (counteract) the unwanted T.
- Taking T-blockers (such as spironolactone or bicalutamide) will do what it says on the tin, and block T from doing the jobs it’s trying to do, but the side-effects are considered sufficient to not prescribe them to most people.
- Taking spearmint or saw palmetto will lower testosterone’s effects
- Scientists aren’t sure how or why spearmint works for this
- Saw palmetto blocks testosterone’s conversion into a more potent form, DHT, and so “detoothes” it a bit. It works similarly to drugs such as finasteride, often prescribed for androgenic alopecia, called “male pattern baldness”, but it affects plenty of women too.
In the case of low levels of FSH, eating leafy greens will help.
In the case of high levels of FSH, see a doctor. HRT (Hormone Replacement Therapy) may help. If you’re not of menopausal age, it could be a sign something else is amiss, so it could be worth getting that checked out too.
What can I eat to boost my estrogen levels naturally?
A common question. The simple answer is:
- Flaxseeds and soy contain plant estrogens that the body can’t actually use as such (too incompatible). They’ve lots of high-quality nutrients though, and the polyphenols and isoflavones can help with some of the same jobs when it comes to sexual health.
- Fruit, especially peaches, apricots, blueberries, and strawberries, contain a lot of lignans and also won’t increase your E levels as such, but will support the same functions and reduce your breast cancer risk.
- Nuts, especially almonds (yay!), cashews, and pistachios, contain plant estrogens that again can’t be used as bioidentical estrogen (like you’d get from your ovaries or the pharmacy) but do support heart health.
- Leafy greens and cruciferous vegetables support a lot of bodily functions including good hormonal health generally, in ways that are beyond the scope of this article, but in short: do eat your greens!
Note: because none of these plant-estrogens or otherwise estrogenic nutrients can actually do the job of estradiol (the main form of estrogen in your body), this is why they’re still perfectly healthy for men to eat too, and—contrary to popular “soy boy” social myths—won’t have any feminizing effects whatsoever.
On the contrary, most of the same foods support good testosterone-related health in men.
The bottom line:
- Our hormones are very special, and cannot be replaced with any amount of herbs or foods.
- We can support our body’s natural hormonal functions with good diet, though.
- Our hormones naturally fluctuate, and are broadly self-correcting.
- If something gets seriously out of whack, you need an endocrinologist, not a homeopath or even a dietician.

How to Use Topical Estrogen Cream For Aging Skin
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.
Dr. Sam Ellis, dermatologist, explains:
Tackling the cause
Estrogen is important for very many aspects of health beyond the sexual aspects. When it comes to skin, a drop in estrogen (usually because of menopause) leads to changes like collagen loss, dryness, reduced elasticity, and slower wound healing. Applying estrogen creams to the skin can reverse these changes.
If your estrogen levels are already within normal pre-menopausal female ranges, by the way, there isn’t so much science to indicate its benefit when used topically. If you are already on systemic HRT (i.e., you take estrogen already to raise your blood estrogen levels and affect your body in its entirety), you may or may not gain extra benefits from the topical cream, depending on factors such as your estrogen dose, your route of administration, your cardiovascular health, and other factors.
For those with lower estrogen and not currently on HRT, you may be wondering: can topical estrogen cream affect systemic estrogen levels? And the answer is that it mostly depends on the dose. In other words: it’s definitely possible, but for most people it’s unlikely.
As ever, if thinking of taking up any hormonal treatment, do consult an endocrinologist and/or gynecologist, and if you have an increased breast cancer risk (for example genetically or prior history), then an oncologist too, just to be safe.
That sounds like a lot of scary things, but mostly it’s just to be on the safe side. The dose of estrogen is very low in topical creams, and even then, only a tiny amount is used per day.

How Ibogaine Can Beat Buprenorphine For Beating Addictions
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.
It’s Q&A Day at 10almonds!
Have a question or a request? We love to hear from you!
In cases where we’ve already covered something, we might link to what we wrote before, but will always be happy to revisit any of our topics again in the future too—there’s always more to say!
As ever: if the question/request can be answered briefly, we’ll do it here in our Q&A Thursday edition. If not, we’ll make a main feature of it shortly afterwards!
So, no question/request too big or small
❝Questions?❞
It seems that this week, everyone was so satisfied with our information, that we received no questions! (If you sent one and we somehow missed it, please accept our apologies and do bring our attention to it)
However, we did receive some expert feedback that we wanted to share because it’s so informative:
❝I work at a detox rehab in Mexico, where we can use methods not legal in the United States. Therefore, while much of the linked articles had useful information, I’m in the “trenches” every day, and there’s some information I’d like to share that you may wish to share, with additional information:
- Buprenorphine is widely used and ineffective for addiction because it’s synthetic and has many adverse side effects. For heavy drug users it isn’t enough and they still hit the streets for more opioid, resulting in fentanyl deaths. Depending on length of usage and dose, it can take WEEKS to get off of, and it’s extremely difficult.
- Ibogaine is the medicine we use to detox people off opiates, alcohol, meth as well as my own specialty, bulimia. It’s psychoactive and it temporarily “resets” the brain to a pre-addictive state. Supplemented by behavior and lifestyle changes, as well as addressing the traumas that led to the addiction is extremely effective.
Our results are about 50%, meaning the client is free of the substance or behavior 1 year later. Ibogaine isn’t a “magic pill” or cure, it’s an opening tool that makes the difficult work of reclaiming one’s life easier.
Ibogaine is not something that should be done outside a medical setting. It requires an EKG to ensure the heart is healthy and doesn’t have prolonged QT intervals; also blood testing to ensure organs are functioning (especially the liver) and mineral levels such as magnetic and potassium are where they should be. It is important that this treatment be conducted by experienced doctors or practitioners, and monitoring vital signs constantly is imperative.
I’m taking time to compose this information because it needs to be shared that there is an option available most people have not heard about.❞
~ 10almonds reader (slightly edited for formatting and privacy)
Thank you for that! Definitely valuable information for people to know, and (if applicable for oneself or perhaps a loved one) ask about when it comes to local options.
We see it’s also being studied for its potential against other neurological conditions, too:
❝The combination of ibogaine and antidepressants produces a synergistic effect in reducing symptoms of psychiatric disorders such as bipolar disorder, depression, schizophrenia, paranoia, anxiety, panic disorder, mania, post-traumatic stress disorder (PTSD), and obsessive–compulsive disorder. Though ibogaine and the antidepressant act in different pathways, together they provide highly efficient therapeutic responses compared to when each of the active agents is used alone.❞

You can now order all kinds of medical tests online. Our research shows this is (mostly) a bad idea
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.
Many of us have done countless rapid antigen tests (RATs) over the course of the pandemic. Testing ourselves at home has become second nature.
But there’s also a growing worldwide market in medical tests sold online directly to the public. These are “direct-to-consumer” tests, and you can access them without seeing a doctor.
While this might sound convenient, the benefits to most consumers are questionable, as we discovered in a recent study.
What are direct-to-consumer tests?
Let’s start with what they’re not. We’re not talking about patients who are diagnosed with a condition, and use tests to monitor themselves (for example, finger-prick testing to monitor blood sugar levels for people with diabetes).
We’re also not talking about home testing kits used for population screening, such as RATs for COVID, or the “poo tests” sent to people aged 50 and over for bowel cancer screening.
Direct-to-consumer tests are products marketed to anyone who is willing to pay, without going through their GP. They can include hormone profiling tests, tests for thyroid disease and food sensitivity tests, among many others.
Some direct-to-consumer tests allow you to complete the test at home, while self-collected lab tests give you the equipment to collect a sample, which you then send to a lab. You can now also buy pathology requests for a lab directly from a company without seeing a doctor.
What we did in our study
We searched (via Google) for direct-to-consumer products advertised for sale online in Australia between June and December 2021. We then assessed whether each test was likely to provide benefits to those who use them based on scientific literature published about the tests, and any recommendations either for or against their use from professional medical organisations.
We identified 103 types of tests and 484 individual products ranging in price from A$12.99 to A$1,947.
We concluded only 11% of these tests were likely to benefit most consumers. These included tests for STIs, where social stigma can sometimes discourage people from testing at a clinic.
A further 31% could possibly benefit a person, if they were at higher risk. For example, if a person had symptoms of thyroid disease, a test may benefit them. But the Royal Australian College of General Practitioners does not recommend testing for thyroid disease in people without symptoms because evidence showing benefits of identifying and treating people with early thyroid disease is lacking.
Some 42% were commercial “health checks” such as hormone and nutritional status tests. Although these are legitimate tests – they may be ordered by a doctor in certain circumstances, or be used in research – they have limited usefulness for consumers.
A test of your hormone or vitamin levels at a particular time can’t do much to help you improve your health, especially because test results change depending on the time of day, month or season you test.
Most worryingly, 17% of the tests were outright “quackery” that wouldn’t be recommended by any mainstream health practitioner. For example, hair analysis for assessing food allergies is unproven and can lead to misdiagnosis and ineffective treatments.
More than half of the tests we looked at didn’t state they offered a pre- or post-test consultation.
Products available may change outside the time frame of our study, and direct-to-consumer tests not promoted or directly purchasable online, such as those offered in pharmacies or by commercial health clinics, were not included.
But in Australia, ours is the first and only study we know of mapping the scale and variety of direct-to-consumer tests sold online.
Research from other countries has similarly found a lack of evidence to support the majority of direct-to-consumer tests.
4 questions to ask before you buy a test online
Many direct-to-consumer tests offer limited benefits, and could even lead to harms. Here are four questions you should ask yourself if you’re considering buying a medical test online.
1. If I do this test, could I end up with extra medical appointments or treatments I don’t need?
Doing a test yourself might seem harmless (it’s just information, after all), but unnecessary tests often find issues that would never have caused you problems.
For example, someone taking a diabetes test may find moderately high blood sugar levels see them labelled as “pre-diabetic”. However, this diagnosis has been controversial, regarded by many as making patients out of healthy people, a large number of whom won’t go on to develop diabetes.
2. Would my GP recommend this test?
If you have worrying symptoms or risk factors, your GP can recommend the best tests for you. Tests your GP orders are more likely to be covered by Medicare, so will cost you a lot less than a direct-to-consumer test.
3. Is this a good quality test?
A good quality home self-testing kit should indicate high sensitivity (the proportion of true cases that will be accurately detected) and high specificity (the proportion of people who don’t have the disease who will be accurately ruled out). These figures should ideally be in the high 90s, and clearly printed on the product packaging.
For tests analysed in a lab, check if the lab is accredited by the National Association of Testing Authorities. Avoid tests sent to overseas labs, where Australian regulators can’t control the quality, or the protection of your sample or personal health information.
4. Do I really need this test?
There are lots of reasons to want information from a test, like peace of mind, or just curiosity. But unless you have clear symptoms and risk factors, you’re probably testing yourself unnecessarily and wasting your money.
Direct-to-consumer tests might seem like a good idea, but in most cases, you’d be better off letting sleeping dogs lie if you feel well, or going to your GP if you have concerns.

Treadmill vs Road
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.
Have a question or a request? We love to hear from you!
In cases where we’ve already covered something, we might link to what we wrote before, but will always be happy to revisit any of our topics again in the future too—there’s always more to say!
As ever: if the question/request can be answered briefly, we’ll do it here in our Q&A Thursday edition. If not, we’ll make a main feature of it shortly afterwards!
So, no question/request too big or small 😎
❝Why do I get tired much more quickly running outside, than I do on the treadmill? Every time I get worn out quickly but at home I can go for much longer!❞
Short answer: the reason is Newton’s laws of motion.
In other words: on a treadmill, you need only maintain your position in space relative the the Earth while the treadmill moves beneath you, whereas on the road, you need to push against the Earth with sufficient force to move it relative to your body.
Illustrative thought experiment to make that clearer: if you were to stand on a treadmill with roller skates, and hold onto the bar with even just one finger, you would maintain your speed as far as the treadmill’s computer is concerned—whereas to maintain your speed on a flat road, you’d still need to push with your back foot every few yards or so.
More interesting answer: it’s a qualitatively different exercise (i.e. not just quantitively different). This is because of all that pushing you’re having to do on the road, while on a treadmill, the only pushing you have to do is just enough to counteract gravity (i.e. to keep you upright).
As such, both forms of running are a cardio exercise (because simply moving your legs quickly, even without having to apply much force, is still something that requires oxygenated blood feeding the muscles), but road-running adds an extra element of resistance exercise for the muscles of your lower body. Thus, road-running will enable you to build-maintain muscle much more than treadmill-running will.
Some extra things to bear in mind, however:
1) You can increase the resistance work for either form of running, by adding weight (such as by wearing a weight vest):
Weight Vests Against Osteoporosis: Do They Really Build Bone?
…and while road-running will still be the superior form of resistance work (for the reasons we outlined above), adding a weight vest will still be improving your stabilization muscles, just as it would if you were standing still while holding the weight up.
2) Stationary cycling does not have the same physics differences as stationary running. By this we mean: an exercise bike will require your muscles to do just as much pushing as they would on a road. This makes stationary cycling an excellent choice for high intensity resistance training (HIRT):
3) The best form of exercise is the one that you will actually do. Thus, when it’s raining sidewise outside, a treadmill inside will get exercise done better than no running at all. Similarly, a treadmill exercise session takes a lot less preparation (“switch it on”) than a running session outside (“get dressed appropriately for the weather, apply sunscreen if necessary, remember to bring water, etc etc”), and thus is also much more likely to actually occur. The ability to stop whenever one wants is also a reassuring factor that makes one much more likely to start. See for example:
