We’ve written before about the benefits of High-Intensity Interval Training (HIIT), but there’s more to say than we can fit in a short article!

Dr. Michael Mosley, who hates exercise but knows his stuff when it comes to the benefits, teamed up with Peta Bee, who loves exercise and is a science journalist with degrees in sports science and nutrition, to bring us this book.

In it, we learn a lot about:

  • the science of HIIT
  • what makes it so different from most kinds of exercise
  • exactly what benefits one can expect

…in a very detailed clinical fashion (while still remaining very readable).

By “very detailed clinical fashion”, here we mean “one minute of this kind of exercise this many times per week over this period of time will give this many extra healthy life-years”, for example, along with lots of research to back numbers, and explanations of the mechanisms of action (e.g. reducing inflammatory biomarkers of aging, increasing cellular apoptosis, improving cardiometabolic stats for reduced CVD risk, and many things)

There’s also time/space given over to exactly what to do and how to do it, giving enough options to suit personal tastes/circumstances.

Bottom line: if you’d like to make your exercise work a lot harder for you while you spend a lot less time working out, then this book will help you do just that!

  • How To Grow In Comfort

    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 To Grow (Without Leaving Your Comfort Zone)

    “You have to get out of your comfort zone!” we are told, from cradle to grave.

    When we are young, we are advised (or sometimes more forcefully instructed!) that we have to try new things. In our middle age, we are expected to be the world’s greatest go-getters, afraid of nothing and always pushing limits. And when we are old, people bid us “don’t be such a dinosaur”.

    It is assumed, unquestioned, that growth can only occur through hardship and discomfort.

    But what if that’s a discomforting lie?

    Butler (2023) posited an idea: “We never achieve success faster and with less effort than when we are in our comfort zone”

    Her words are an obvious callback to the ideas of Csikszentmihalyi (1970) in the sense of “flow”, in the sense in which that word is used in psychology.

    Flow is: when a person is in a state of energized focus, full involvement, and enjoyment of an activity.

    As a necessary truth (i.e: a function of syllogistic logic), the conditions of “in a state of flow” and “outside of one’s comfort zone” cannot overlap.

    From there, we can further deduce (again by simple logic) that if flow can be found, and/but cannot be found outside of the comfort zone, then flow can only be found within the comfort zone.

    That is indeed comforting, but what about growth?

    Imagine you’ve never gone camping in your life, but you want to get outside of your comfort zone, and now’s the time to do it. So, you check out some maps of the Yukon, purchase some camping gear, and off you go into the wilderness. In the event that you survive to report it, you will indeed be able to say “it was not comfortable”.

    But, did growth occur? Maybe, but… it’s a folly to say “what doesn’t kill us makes us stronger” as a reason to pursue such things. Firstly, there’s a high chance it may kill us. Secondly, what doesn’t kill us often leaves us incredibly weakened and vulnerable.

    When Hannibal famously took his large army of mostly African mercenaries across the Alps during winter to march on Rome from the other side, he lost most of his men on the way, before proceeding to terrorize Northern Italy convincingly with the small remainder. But! Their hard experience hadn’t made them stronger; it had just removed the weaker soldiers, making the resultant formations harder to break.

    All this to say, please do not inflict hardship and discomfort and danger in the hopes it’ll make you stronger; it will probably do the opposite.

    But…

    If, instead of wilderness trekking in the Yukon…

    • You start off with a camper van holiday, then you’ll be taking a fair amount of your comfort with you. In effect, you will be stretching and expanding your comfort zone without leaving it.
    • Then maybe another year you might try camping in a tent on a well-catered camping site.
    • Later, you might try “roughing it” at a much less well-catered camping site.
    • And so on.

    Congratulations, you have tried new things and undergone growth, taking your comfort zone with you all the way!

    This is more than just “easing yourself into” something

    It really is about taking your comfort with you too. If you want to take up running, don’t ask “how can I run just a little bit first” or “how can I make it easier” (well, feel free to ask those things too, but) ask yourself: how can I bring my comfort with me? Comfortable shoes, perhaps, an ergonomic water bottle, shade for your head, maybe.

    ❝Any fool can rough it, but a good soldier can make himself comfortable in any circumstances❞

    ~ British Army maxim

    This goes for more than just physical stuff, too

    If you want to learn a new skill, the initial learning curve can be anxiety-inducing, especially if you are taking a course and worried about keeping up or “not being good enough”.

    So, “secretly” study in advance, at your leisure, get yourself a head start. Find a degree of comfort in what you’ve learned so far, and then bring that comfort with you into your entry-level course that is now less intimidating.

    Discomfort isn’t a badge of honor (and impedes growth)

    Take that extra rest stop on the highway. Bring your favorite coffee with you. Use that walking stick, if it helps.

    Whatever it takes to bring your comfort with you, bring it.

    Trust us, you’ll get further that way.

  • Biohack Your Brain – by Dr. Kristen Willeumier

    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.

    The title of this book is a little misleading, as it’s not really about biohacking; it’s more like a care and maintenance manual for the brain.

    This distinction is relevant, because to hack a thing is to use it in a way it’s not supposed to be used, and/or get it to do something it’s not supposed to do.

    Intead, what neurobiologist Dr. Kristen Willeumier offers us is much more important: how to keep our brain in good condition.

    She takes us through the various things that our brain needs, and what will happen if it doesn’t get them. Some are dietary, some are behavioral, some are even cognitive.

    A strength of this book is not just explaining what things are good for the brain, but also: why. Understanding the “why” can be the motivational factor that makes a difference between us doing the thing or not!

    For example, if we know that exercise is good for the brain, we think “sounds reasonable” and carry on with what we were doing. If, however, we also understand how increased bloodflow helps with the timely removal of beta-amyloids that are associated with Alzheimer’s, we’re more likely to make time for getting that movement going.

    Bottom line: there are key things we can do to keep our brain healthy, and you probably wouldn’t want to miss any. This book is a great care manual for such!

  • When the Body Says No – by Dr. Gabor Maté

    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 know that chronic stress is bad for us because of what it does to our cortisol levels, so what is the rest of this book about?

    Dr. Gabor Maté is a medical doctor, heavily specialized in the impact of psychological trauma on long term physical health.

    Here, he examies—as the subtitle promises—the connection between stress and disease. As it turns out, it’s not that simple.

    We learn not just about the impact that stress has on our immune system (including increasing the risk of autoimmune disorders like rheumatoid arthritis), the cardiovascular system, and various other critical systems fo the body… But also:

    • how environmental factors and destructive coping styles contribute to the onset of disease, and
    • how traumatic events can warp people’s physical perception of pain
    • how certain illnesses are associated with particular personality types.

    This latter is not “astrology for doctors”, by the way. It has more to do with what coping strategies people are likely to employ, and thus what diseases become more likely to take hold.

    The book has practical advice too, and it’s not just “reduce your stress”. Ideally, of course, indeed reduce your stress. But that’s a) obvious b) not always possible. Rather, Dr. Maté explains which coping strategies result in the least prevalence of disease.

    In terms of writing style, the book is very much easy-reading, but be warned that (ironically) this isn’t exactly a feel-good book. There are lot of tragic stories in it. But, even those are very much well-worth reading.

    Bottom line: if you (and/or a loved one) are suffering from stress, this book will give you the knowledge and understanding to minimize the harm that it will otherwise do.

  • Burned Out By Tuesday?

    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.

    Avoiding Burnout, The Active Way

    This is Dr. Claudine Holt. She’s double board-certified, in Occupational & Environmental Medicine, and Lifestyle Medicine.

    In short: preventative medicine in all parts of our life.

    Hopefully, you are reading this bright-eyed and bushy-tailed and ready to take on another exciting day in this wonderful, beautiful world!

    On the other hand, it’s possible that you’re reading this semi-focussed, looking for a crumb of dopamine as much as you are looking for information.

    If you’ve ever had the “What a week!” / “It’s only Tuesday” moment, this one’s for you.

    What does Dr. Holt want us to know?

    You can recover from burnout without guilt

    Sometimes, we overreach ourselves. Sometimes, life overreaches us! Sometimes it’s not that we overcommitted—it’s just that we were taking each day as it comes, but sometimes several days gang up on us at once.

    Sometimes, even, we can feel exhausted when it seems like we haven’t done anything.

    Note: if you feel exhausted and it seems like you haven’t done anything, then be aware: you are exhausted for a reason!

    What that reason might be may vary, but contrary to popular belief, energy does not just vanish. It went somewhere.

    This goes double if you have any chronic illness(es), even if you’re not aware of having had a flare-up, chances are you were just exceptionally busy (on a cellular level).

    And it’s easy to think that “mere” cellular activity shouldn’t be exhausting, but that is 100% of where our energy transactions happen—whether or not we are consciously aware of them!

    See also: Eat To Beat Chronic Fatigue ← yes, this also covers when you are too exhausted to shop and cook like a TV chef

    Dr. Holt specializes in working with burned out medical professionals (and also specifically specializes in working with women), but there are lessons for everyone in her advice. For example:

    Fiction: ”Medicine is my calling–it’s who I am.”

    Fact: You are more than medicine! Remember that your career is just one aspect of your life. Don’t forget to create your big-picture vision and tend the garden of the other areas of your life too.

    ~ Dr. Claudine Holt

    Read more: Dr. Claudine Holt | Burnout: Fact vs Fiction

    This same thing can go for whatever part of your identity frequently follows “I’m a…”, and is somewhere that you put a lot of your energy; it could equally be a non-professional job like “homemaker”, or a relational status like “husband”, or a cultural identifier like “Christian”, or a hobby like “gardener” (assuming that is not also your profession, in which case, same item, different category).

    Indeed, a lot of women especially get hit by “the triple burden” of professional work, housework, and childcare. And it’s not even necessarily that we resent any of those things or feel like they’re a burden; we (hopefully) love our professions, homes, children. But, here’s the thing:

    No amount of love will add extra hours to the day.

    So what does she recommend doing about it, when sometimes we’re juggling things that can’t be dropped?

    Start simple, but start!

    Dr. Holt recommends to start with a smile (yes even if, and sometimes especially when, the circumstances do not feel like they merit it), and deploy some CBT tools:

    Two Hacks to Quickly Rise Above Burnout (Or Any Circumstance)

    We’ve expanded on this topic here:

    How To Manage Chronic Stress

    With a more level head on, it becomes easier to take on the next step, which creating healthy boundariesand that doesn’t just mean with other people!

    It also means slaying our own perfectionism and imposter syndrome—both things that will have us chasing our tails 36 hours per day if we let them.

    See also:

    ❝Burnout is the culture of our times. A culture that expects us to do more and think our way out of everything. A culture that asks for more than the body can bear. Unfortunately, even though the situation might not be of our creation, burnout culture is our inheritance.

    An inheritance we can either perpetuate—or change—depending on what we embody.❞

    Source: The Embodied MD on Burnout with Dr Claudine Holt

    That “embodiment” is partly our choices and actions that we bring and own just as we bring and own our body—and it’s partly our relationship with our body itself, and learning to love it, and work with it to achieve wonderful things, instead of just getting through the day.

    Which yes, does also mean making space for good diet, exercise, sleep and so forth, per:

  • Statins: His & Hers?

    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.

    The Hidden Complexities of Statins and Cardiovascular Disease (CVD)

    This is Dr. Barbara Roberts. She’s a cardiologist and the Director of the Women’s Cardiac Center at one of the Brown University Medical School teaching hospitals. She’s an Associate Clinical Professor of Medicine and takes care of patients, teaches medical students, and does clinical research. She specializes in gender-specific aspects of heart disease, and in heart disease prevention.

    We previously reviewed Dr. Barbara Roberts’ excellent book “The Truth About Statins: Risks and Alternatives to Cholesterol-Lowering Drugs”. It prompted some requests to do a main feature about Statins, so we’re doing it today. It’s under the auspices of “Expert Insights” as we’ll be drawing almost entirely from Dr. Roberts’ work.

    So, what are the risks of statins?

    According to Dr. Roberts, one of the biggest risks is not just drug side-effects or anything like that, but rather, what they simply won’t treat. This is because statins will lower LDL (bad) cholesterol levels, without necessarily treating the underlying cause.

    Imagine you got Covid, and it’s one of the earlier strains that’s more likely deadly than “merely” debilitating.

    You’re coughing and your throat feels like you gargled glass.

    Your doctor gives you a miracle cough medicine that stops your coughing and makes your throat feel much better.

    (Then a few weeks later, you die, because this did absolutely nothing for the underlying problem)

    You see the problem?

    Are there problematic side-effects too, though?

    There can be. But of course, all drugs can have side effects! So that’s not necessarily news, but what’s relevant here is the kind of track these side-effects can lead one down.

    For example, Dr. Roberts cites a case in which a woman’s LDL levels were high and she was prescribed simvastatin (Zocor), 20mg/day. Here’s what happened, in sequence:

    1. She started getting panic attacks. So, her doctor prescribed her sertraline (Zoloft) (a very common SSRI antidepressant) and when that didn’t fix it, paroxetine (Paxil). This didn’t work either… because the problem was not actually her mental health. The panic attacks got worse…
    2. Then, while exercising, she started noticing progressive arm and leg weakness. Her doctor finally took her off the simvastatin, and temporarily switched to ezetimibe (Zetia), a less powerful nonstatin drug that blocks cholesterol absorption, which change eased her arm and leg problem.
    3. As the Zetia was a stopgap measure, the doctor put her on atorvastatin (Lipitor). Now she got episodes of severe chest pressure, and a skyrocketing heart rate. She also got tremors and lost her body temperature regulation.
    4. So the doctor stopped the atorvastatin and tried rosovastatin (Crestor), on which she now suffered exhaustion (we’re not surprised, by this point) and muscle pains in her arms and chest.
    5. So the doctor stopped the rosovastatin and tried lovastatin (Mevacor), and now she had the same symptoms as before, plus light-headedness.
    6. So the doctor stopped the lovastatin and tried fluvastatin (Lescol). Same thing happened.
    7. So he stopped the fluvastatin and tried pravastatin (Pravachol), without improvement.
    8. So finally he took her off all these statins because the high LDL was less deleterious to her life than all these things.
    9. She did her own research, and went back to the doctor to ask for cholestyramine (Questran), which is a bile acid sequestrent and nothing to do with statins. She also asked for a long-acting niacin. In high doses, niacin (one of the B-vitamins) raises HDL (good) cholesterol, lowers LDL, and lowers tryglycerides.
    10. Her own non-statin self-prescription (with her doctor’s signature) worked, and she went back to her life, her work, and took up running.

    Quite a treatment journey! Want to know more about the option that actually worked?

    Read: Bile Acid Resins or Sequestrants

    What are the gender differences you/she mentioned?

    A lot of this is still pending more research—basically it’s a similar problem in heart disease to one we’ve previously talked about with regard to diabetes. Diabetes disproportionately affects black people, while diabetes research disproportionately focuses on white people.

    In this case, most heart disease research has focused on men, with women often not merely going unresearched, but also often undiagnosed and untreated until it’s too late. And the treatments, if prescribed? Assumed to be the same as for men.

    Dr. Roberts tells of how medicine is taught:

    ❝When I was in medical school, my professors took the “bikini approach” to women’s health: women’s health meant breasts and reproductive organs. Otherwise the prototypical patient was presented as a man.❞

    There has been some research done with statins and women, though! Just, still not a lot. But we do know for example that some statins can be especially useful for treating women’s atherosclerosis—with a 50% success rate, rather than 31% for men.

    For lowering LDL, it can work but is generally not so hot in women.

    Fun fact:

    In men:

    • High total cholesterol
    • High non-HDL cholesterol
    • High LDL cholesterol
    • Low HDL cholesterol

    …are all significantly associated with an increased risk of death from CVD.

    In women:

    …levels of LDL cholesterol even more than 190 were associated with only a small, statistically insignificant increased risk of dying from CVD.

    So…

    The fact that women derive less benefit from a medicine that mainly lowers LDL cholesterol, may be because elevated LDL cholesterol is less harmful to women than it is to men.

    And also: Treatment and Response to Statins: Gender-related Differences

    And for that matter: Women Versus Men: Is There Equal Benefit and Safety from Statins?*

    Definitely a case where Betteridge’s Law of Headlines applies!

    What should women do to avoid dying of CVD, then?

    First, quick reminder of our general disclaimer: we can’t give medical advice and nothing here comprises such. However… One particularly relevant thing we found illuminating in Dr. Roberts’ work was this observation:

    The metabolic syndrome is diagnosed if you have three (or more) out of five of the following:

    1. Abdominal obesity (waist >35″ if a woman or >40″ if a man)
    2. Fasting blood sugars of 100mg/dl or more
    3. Fasting triglycerides of 150mg/dl or more
    4. Blood pressure of 130/85 or higher
    5. HDL <50 if a woman or <40 if a man

    And yet… because these things can be addressed with exercise and a healthy diet, which neither pharmaceutical companies nor insurance companies have a particular stake in, there’s a lot of focus instead on LDL levels (since there are a flock of statins that can be sold be lower them)… Which, Dr. Roberts says, is not nearly as critical for women.

    So women end up getting prescribed statins that cause panic attacks and all those things we mentioned earlier… To lower our LDL, which isn’t nearly as big a factor as the other things.

    In summary:

    Statins do have their place, especially for men. They can, however, mask underlying problems that need treatment—which becomes counterproductive.

    When it comes to women, statins are—in broad terms—statistically not as good. They are a little more likely to be helpful specifically in cases of atherosclerosis, whereby they have a 50/50 chance of helping.

    For women in particular, it may be worthwhile looking into alternative non-statin drugs, and, for everyone: diet and exercise.

  • Healthy Butternut Macaroni Cheese

    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.

    A comfort food classic, healthy and plant-based, without skimping on the comfort.

    You will need

    • ½ butternut squash, peeled and cut into small pieces (if buying ready-chopped, this should be about 1 lb)
    • 1 onion, chopped
    • ¼ bulb garlic
    • 2 tbsp extra virgin olive oil
    • 12 oz (or thereabouts) wholegrain macaroni, or similar pasta shape (even penne works fine—which is good, as it’s often easier to buy wholegrain penne than wholegrain macaroni) (substitute with a gluten-free pasta such as buckwheat pasta, if avoiding gluten)
    • 6 oz (or thereabouts) cashews, soaked in hot water for at least 15 minutes (but longer is better)
    • ½ cup milk (your preference what kind; we recommend hazelnut for its mellow nutty flavor)
    • 3 tbsp nutritional yeast
    • Juice of ½ lemon
    • 2 tsp black pepper, coarse ground
    • ½ tsp MSG, or 1 tsp low-sodium salt
    • Optional: smoked paprika, to serve

    Note: if you are allergic to nuts, please accept our apologies that there’s no substitution available in this one. Simply put, removing the cashews would mean changing most of the rest of the recipe to compensate, so there’s no easy “or substitute with…” that we can mention. We’ll have to find/develop a good healthy plant-based no-nuts recipe for you at a later date.

    Method

    (we suggest you read everything at least once before doing anything)

    1) Preheat the oven to 400℉ / 200℃.

    2) Combine the butternut squash, onion, and garlic with the olive oil, in a large roasting tin, tossing thoroughly to ensure an even coat of oil. Roast them for about 25 minutes until soft.

    3) Cook the macaroni while you wait (this should take about 10 minutes or so in salted water), drain, and rinse thoroughly in cold water, before setting aside. This cooling increases the pasta’s resistant starch content (that’s good, for your gut and for your blood sugars, and thus also for your heart and brain), and it will maintain this benefit even when we reheat it later.

    4) Drain the cashews, and tip them into a high-speed blender with the milk, and process until smooth. Add the roasted vegetables and the remaining ingredients apart from the pasta, and continue to process until again smooth. You can add a little more milk if you need to, but go easy with it.

    5) Heat the sauce (that you just made in the food processor) gently in a saucepan, and refresh the pasta by pouring a kettle of boiling water through it in a colander.

    6) Optional: combine the pasta and sauce in an ovenproof dish or cast iron pan, and give it a few minutes under the hottest grill (or browning iron, if you have such) your oven can muster. Alternatively, use a culinary blowtorch, if you have one.

    7) Serve; and if you didn’t do the optional step above, this means combining the pasta and sauce. You can also dust the top with some extra seasonings if you like. Smoked paprika works well for this.

    Enjoy!
