Authors often try to bring forward the best minds of the distant past, and apply them to today’s world. One could fill a library with business advice adaptations from Sun Tzu’s Art of War alone, same goes for Miyamoto Musashi’s Book of Five Rings, and let’s not get started on Niccolò Machiavelli. What makes this book different?

Michael Gelb explores the principles codified and used by the infamous Renaissance Man to do exactly what he did: pretty much everything. Miyamoto Musashi had no interest in business, but Leonardo da Vinci really did care a lot about learning, creating, problem-solving, human connections, and much more. And best of all, he took notes. So many notes, for himself, of which we now enjoy the benefit.

How To Think Like Leonardo da Vinci explores these notes and their application by the man himself, and gives real, practical examples of how you can (and why you should) put them into action in your daily life, no matter whether you are a big business CEO or a local line cook or a reclusive academic, Leonardo has lessons for you.

  • The BAT-pause!

    When Cold Weather & The Menopause Battle It Out

    You may know that (moderate, safe) exposure to the cold allows our body to convert our white and yellow fat into the much healthier brown fat—also called brown adipose tissue, or “BAT” to its friends.

    If you didn’t already know that, then well, neither did scientists until about 15 years ago:

    The Changed Metabolic World with Human Brown Adipose Tissue: Therapeutic Visions

    You can read more about it here:

    Cool Temperature Alters Human Fat and Metabolism

    This is important, especially because the white fat that gets converted is the kind that makes up most visceral fat—the kind most associated with all-cause mortality:

    Visceral Belly Fat & How To Lose It ← this is not the same as your subcutaneous fat, the kind that sits directly under your skin and keeps you warm; this is the fat that goes between your organs and of which we should only have a small amount!

    The BAT-pause

    It’s been known (since before the above discovery) that BAT production slows considerably as we get older. Not too shocking—after all, many metabolic functions slow as we get older, so why should fat regulation be any different?

    But! Rodent studies found that this was tied less to age, but to ovarian function: rats who underwent ovariectomies suffered reduced BAT production, regardless of their age.

    Naturally, it’s been difficult to recreate such studies in humans, because it’s difficult to find a large sample of young adults willing to have their ovaries whipped out (or even suppressed chemically) to see how badly their metabolism suffers as a result.

    Nor can an observational study (for example, of people who incidentally have ovaries removed due to ovarian cancer) usefully be undertaken, because then the cancer itself and any additional cancer treatments would be confounding factors.

    Perimenopausal study to the rescue!

    A recent (published last month, at time of writing!) study looked at women around the age of menopause, but specifically in cohorts before and after, measuring BAT metabolism.

    By dividing the participants into groups based on age and menopausal status, and dividing the post-menopausal group into “takes HRT” and “no HRT” groups, and dividing the pre-menopausal group into “normal ovarian function” and “ovarian production of estrogen suppressed to mimic slightly early menopause” groups (there’s a drug for that), and then having groups exposed to warm and cold temperatures, and measuring BAT metabolism in all cases, they were able to find…

    It is about estrogen, not age!

    You can read more about the study here:

    “Good” fat metabolism changes tied to estrogen loss, not necessarily to aging, shows study

    …and the study itself, here:

    Brown adipose tissue metabolism in women is dependent on ovarian status

    What does this mean for men?

    This means nothing directly for (cis) men, sorry.

    But to satisfy your likely curiosity: yes, testosterone does at least moderately suppress BAT metabolism—based on rodent studies, anyway, because again it’s difficult to find enough human volunteers willing to have their testicles removed for science (without there being other confounding variables in play, anyway):

    Testosterone reduces metabolic brown fat activity in male mice

    So, that’s bad per se, but there isn’t much to be done about it, since the rest of your (addressing our male readers here) metabolism runs on testosterone, as do many of your bodily functions, and you would suffer many unwanted effects without it.

    However, as men do typically have notably less body fat in general than women (this is regulated by hormones), the effects of changes in BAT metabolism are rather less pronounced in men (per testosterone level changes) than in women (per estrogen level changes), because there’s less overall fat to convert.

    In summary…

    While menopausal HRT is not necessarily a silver bullet to all metabolic problems, its BAT-maintaining ability is certainly one more thing in its favor.

  • California Becomes Latest State To Try Capping Health Care Spending

    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.

    California’s Office of Health Care Affordability faces a herculean task in its plan to slow runaway health care spending.

    The goal of the agency, established in 2022, is to make care more affordable and accessible while improving health outcomes, especially for the most disadvantaged state residents. That will require a sustained wrestling match with a sprawling, often dysfunctional health system and powerful industry players who have lots of experience fighting one another and the state.

    Can the new agency get insurers, hospitals, and medical groups to collaborate on containing costs even as they jockey for position in the state’s $405 billion health care economy? Can the system be transformed so that financial rewards are tied more to providing quality care than to charging, often exorbitantly, for a seemingly limitless number of services and procedures?

    The jury is out, and it could be for many years.

    California is the ninth state — after Connecticut, Delaware, Massachusetts, Nevada, New Jersey, Oregon, Rhode Island, and Washington — to set annual health spending targets.

    Massachusetts, which started annual spending targets in 2013, was the first state to do so. It’s the only one old enough to have a substantial pre-pandemic track record, and its results are mixed: The annual health spending increases were below the target in three of the first five years and dropped beneath the national average. But more recently, health spending has greatly increased.

    In 2022, growth in health care expenditures exceeded Massachusetts’ target by a wide margin. The Health Policy Commission, the state agency established to oversee the spending control efforts, warned that “there are many alarming trends which, if unaddressed, will result in a health care system that is unaffordable.”

    Neighboring Rhode Island, despite a preexisting policy of limiting hospital price increases, exceeded its overall health care spending growth target in 2019, the year it took effect. In 2020 and 2021, spending was largely skewed by the pandemic. In 2022, the spending increase came in at half the state’s target rate. Connecticut and Delaware, by contrast, both overshot their 2022 targets.

    It’s all a work in progress, and California’s agency will, to some extent, be playing it by ear in the face of state policies and demographic realities that require more spending on health care.

    And it will inevitably face pushback from the industry as it confronts unreasonably high prices, unnecessary medical treatments, overuse of high-cost care, administrative waste, and the inflationary concentration of a growing number of hospitals in a small number of hands.

    “If you’re telling an industry we need to slow down spending growth, you’re telling them we need to slow down your revenue growth,” says Michael Bailit, president of Bailit Health, a Massachusetts-based consulting group, who has consulted for various states, including California. “And maybe that’s going to be heard as ‘we have to restrain your margins.’ These are very difficult conversations.”

    Some of California’s most significant health care sectors have voiced disagreement with the fledgling affordability agency, even as they avoid overtly opposing its goals.

    In April, when the affordability office was considering an annual per capita spending growth target of 3%, the California Hospital Association sent it a letter saying hospitals “stand ready to work with” the agency. But the proposed number was far too low, the association argued, because it failed to account for California’s aging population, new investments in Medi-Cal, and other cost pressures.

    The hospital group suggested a spending increase target averaging 5.3% over five years, 2025-29. That’s slightly higher than the 5.2% average annual increase in per capita health spending over the five years from 2015 to 2020.

    Five days after the hospital association sent its letter, the affordability board approved a slightly less aggressive target that starts at 3.5% in 2025 and drops to 3% by 2029. Carmela Coyle, the association’s chief executive, said in a statement that the board’s decision still failed to account for an aging population, the growing need for mental health and addiction treatment, and a labor shortage.

    The California Medical Association, which represents the state’s doctors, expressed similar concerns. The new phased-in target, it said, was “less unreasonable” than the original plan, but the group would “continue to advocate against an artificially low spending target that will have real-life negative impacts on patient access and quality of care.”

    But let’s give the state some credit here. The mission on which it is embarking is very ambitious, and it’s hard to argue with the motivation behind it: to interject some financial reason and provide relief for millions of Californians who forgo needed medical care or nix other important household expenses to afford it.

    Sushmita Morris, a 38-year-old Pasadena resident, was shocked by a bill she received for an outpatient procedure last July at the University of Southern California’s Keck Hospital, following a miscarriage. The procedure lasted all of 30 minutes, Morris says, and when she received a bill from the doctor for slightly over $700, she paid it. But then a bill from the hospital arrived, totaling nearly $9,000, and her share was over $4,600.

    Morris called the Keck billing office multiple times asking for an itemization of the charges but got nowhere. “I got a robotic answer, ‘You have a high-deductible plan,’” she says. “But I should still receive a bill within reason for what was done.” She has refused to pay that bill and expects to hear soon from a collection agency.

    The road to more affordable health care will be long and chock-full of big challenges and unforeseen events that could alter the landscape and require considerable flexibility.

    Some flexibility is built in. For one thing, the state cap on spending increases may not apply to health care institutions, industry segments, or geographic regions that can show their circumstances justify higher spending — for example, older, sicker patients or sharp increases in the cost of labor.

    For those that exceed the limit without such justification, the first step will be a performance improvement plan. If that doesn’t work, at some point — yet to be determined — the affordability office can levy financial penalties up to the full amount by which an organization exceeds the target. But that is unlikely to happen until at least 2030, given the time lag of data collection, followed by conversations with those who exceed the target, and potential improvement plans.

    In California, officials, consumer advocates, and health care experts say engagement among all the players, informed by robust and institution-specific data on cost trends, will yield greater transparency and, ultimately, accountability.

    Richard Kronick, a public health professor at the University of California-San Diego and a member of the affordability board, notes there is scant public data about cost trends at specific health care institutions. However, “we will know that in the future,” he says, “and I think that knowing it and having that information in the public will put some pressure on those organizations.”

  • The Fast-Mimicking Diet

    Live, Fast, Live Long

    This is Dr. Valter Longo. He’s a biogerontologist and cell biologist, whose work has focused on fasting and nutrient response genes, and how we can leverage them against diseases and aging in general.

    We reviewed his book recently:

    The Longevity Diet: Discover The New Science To Slow Aging, Fight Disease, And Manage Your Weight – by Dr. Valter Longo

    What does he want us to know?

    What to eat

    Dr. Longo recommends a mostly plant-based diet (especially vegetables, whole grains, and legumes), but also having some fish. The bulk of our dietary fats, however, he says are best coming from olive oil and nuts.

    He also advises aiming for nutritional density of vitamins and minerals in our diet, and/but supplementing with a multivitamin once every few days to cover any gaps.

    If in doubt choosing between plant-based whole foods, he recommends that we choose those our ancestors will have eaten.

    When to eat

    Dr. Longo recommends time-restricted eating within a 12-hour window per day.

    See also: Intermittent Fasting: We Sort The Science From The Hype

    However, he also recommends (additionally or separately; it’s up to us; additionally is better but the point is it still has excellent benefits separately too) his “fast-mimicking diet” (FMD), which involves eating according to what we said in “What to eat”, but restricting it to 750 kcal per day, 5 days in a row, but not necessarily 5 days per week.

    For example, the following was a 3-month study that involved doing this for only one 5-day cycle per month:

    ❝Three FMD cycles reduced body weight, trunk, and total body fat; lowered blood pressure; and decreased insulin-like growth factor 1 (IGF-1). No serious adverse effects were reported.

    A post hoc analysis of subjects from both FMD arms showed that body mass index, blood pressure, fasting glucose, IGF-1, triglycerides, total and low-density lipoprotein cholesterol, and C-reactive protein were more beneficially affected in participants at risk for disease than in subjects who were not at risk.

    Thus, cycles of a 5-day FMD are safe, feasible, and effective in reducing markers/risk factors for aging and age-related diseases.❞

    Note: the introduction mentions FMD in mice, but this is just referencing previous studies. This study is about FMD in humans!

    The vast majority of literature out there about ADHD is about children. And fair enough, there are enough popular misunderstandings of ADHD in children so it’s good those works exist… but what about adults?

    Adults face different challenges than children, and have different responsibilities. People have different expectations. And even if you say you have ADHD… If you’re not behaving like a squirrel, they will often not accept this, much less understand it, because half the actual symptoms are not what most people think they are.

    Ross-Child first lays out the neurobiological underpinnings of ADHD. This is a good place to start, because the physiology of it explains a lot of the other parts of it that can otherwise seem quite mystifying.

    Thereafter, he looks one-by-one at the various cognitive and behavioral aspects of ADHD in adults, which will surely help the reader to better understand themself (or perhaps a loved one).

    The next part of the book is given over to an exploration of ADHD and the differences it can make in the workplace, relationships (incl. ADHD and sex), as well as parenting, and how these things can all be navigated better by all concerned.

    The style throughout is light and very readable, peppered with science made comprehensible. If there’s any flaw, it’s that there are only two pages of references in the bibliography—we’d have liked to have seen more.

    All in all though, a really useful guide if you or a loved one has ADHD and you’d like strategies for working with (or around) this condition in a world not made to be kind to such.

  • Imposter Syndrome (and why almost everyone has it)

    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.

    Imposter Syndrome (and why almost everyone has it)

    Imposter syndrome is the pervasive idea that we’re not actually good enough, people think we are better than we are, and at any moment we’re going to get found out and disappoint everyone.

    Beyond the workplace

    Imposter syndrome is most associated with professionals. It can range from a medical professional who feels like they’ve been projecting an image of confidence too much, to a writer or musician who is sure that their next piece will never live up to the acclaim of previous pieces and everyone will suddenly realize they don’t know what they’re doing, to a middle-manager who feels like nobody above or below them realizes how little they know how to do.

    But! Less talked-about (but no less prevalent) is imposter syndrome in other areas of life. New parents tend to feel this strongly, as can the “elders” of a family that everyone looks to for advice and strength and support. Perhaps worst is when the person most responsible for the finances of a household feels like everyone just trusts them to keep everything running smoothly, and maybe they shouldn’t because it could all come crashing down at any moment and everyone will see them for the hopeless shambles of a human being that they really are.

    Feelings are not facts

    And yet (while everyone makes mistakes sometimes) the reality is that we’re all doing our best. Given that imposter syndrome affects up to 82% of people, let’s remember to have some perspective. Everyone feels like they’re winging it sometimes. Everyone feels the pressure.

    Well, perhaps not everyone. There’s that other 18%. Some people are sure they’re the best thing ever. Then again, there’s probably some in that 18% that actually feel worse than the 82%—they just couldn’t admit it, even in an anonymized study.

    But one thing’s for sure: it’s very, very common. Especially in high-performing women, by the way, and people of color. In other words, people who typically “have to do twice as much to get recognized as half as good”.

    That said, the flipside of this is that people who are not in any of those categories may feel “everything is in my favor, so I really have no excuse to not achieve the most”, and can sometimes take very extreme actions to try to avoid perceived failure, and it can be their family that pays the price.

    Things to remember

    If you find imposter syndrome nagging at you, remember these things:

    • There are people far less competent than you, doing the same thing
    • Nobody knows how to do everything themselves, especially at first
    • If you don’t know how to do something, you can usually find out
    • There is always someone to ask for help, or at least advice, or at least support

    At the end of the day, we evolved to eat fruit and enjoy the sun. None of us are fully equipped for all the challenges of the modern world, but if we do our reasonable best, and look after each other (and that means that you too, dear reader, deserve looking after as well), we can all do ok.

  • DVT Risk Management Beyond The Socks

    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

    ❝I know I am at higher risk of DVT after having hip surgery, any advice beside compression stockings?❞

    First of all, a swift and easy recovery to you!

    Surgery indeed increases the risk of deep vein thrombosis (henceforth: DVT), and hip or knee surgery especially so, for obvious reasons.

    There are other risk factors you can’t control, like genetics (family history of DVT as an indicator) and age, but there are some that you can, including:

    • smoking (so, ideally don’t; do speak to your doctor before quitting though, in case withdrawal might be temporarily worse for you than smoking)
    • obesity (so, losing weight is good if overweight, but if this is going to happen, it’ll mostly happen in the kitchen not the gym, which may be a relief as you’re probably not the very most up for exercise at present)
    • sedentariness (so, while you’re probably not running marathons right now, please do try to keep moving, even if only gently)

    Beyond that, yes compression socks, but also frequent gentle massage can help a lot to avoid clots forming.

    Also, no surprises, a healthy diet will help, especially one that’s good for general heart health. Check out for example the Mediterranean DASH diet:

    Four Ways To Upgrade The Mediterranean Diet

    Also, obviously, speak with your doctor/pharmacist if you haven’t already about possible medications, including checking whether any of your current medications increase the risk and could be swapped for something that doesn’t.

    Take care!
