Are You A Calorie-Burning Machine?

Burn, Calorie, Burn

In Tuesday’s newsletter, we asked you whether you count calories, and got the above-depicted, below-described set of answers:

  • About 56% said “I am somewhat mindful of calories but keep only a rough tally”
  • About 32% said “I do not count calories / I don’t think it’s important for my health”
  • About 13% said “I rigorously check and record the calories of everything I consume”

So what does the science say, about the merits of all these positions?

A food’s calorie count is a good measure of how much energy we will, upon consuming the food, have to use or store: True or False?

False, broadly. It can be, at best, a rough guideline. Do you know what a calorie actually is, by the way? Most people don’t.

One thing to know before we get to that: there’s “cal” vs “kcal”. The latter is generally used when it comes to foodstuffs, and it’s what we’ll be meaning whenever we say “calorie” here. 1cal is 1/1000th of a kcal, that’s all.

Now, for what a calorie actually is:

A calorie is the amount of energy needed to raise the temperature of 1 liter of water by 1℃

Question: so, how to we measure how much food is needed to do that?

Answer: by using a bomb calorimeter! Which is the exciting name for the apparatus used to literally burn food and capture the heat produced to indeed raise the temperature of 1 liter of water by 1℃.

If you’re having trouble imagining such equipment, here it is:

Bomb Calorimeter: Definition, Construction, & Operation (with diagram and FAQs)

The unfortunate implication of the above information

A kilogram of sawdust contains about a 1000 kcal, give or take what wood was used and various other conditions.

However, that does not mean you can usefully eat the sawdust. In other words:

Calorie count tells us only how good something is at raising the temperature of water if physically burned.

Now do you see why oils and sugars have such comparably high calorie counts?

And while we may talk about “burning calories” as a metaphor, we do not, in fact, have a little wood stove inside us burning the food we eat.

A calorie is a calorie: True or False?

Definitely False! Building on from the above… We will get very little energy from sawdust; it’s not just that we can’t use it; we can’t store it either; it’ll mostly pass through as fiber.

(however, please do not use sawdust to get your daily dose of fiber either, as it is not safe for human consumption and may give you diseases, depending on what is lurking in it)

But let’s look at oil and sugar, two very high-calorie categories of food, because they’re really easy to physically burn and they give off a good flame.

A bomb calorimeter may treat them quite equally, but to our body, they are metabolically very different indeed.

For a start, most sugars will get absorbed and processed much more quickly than most oils, and that can overwhelm the liver (responsible for glycogen management), and lead to non-alcoholic fatty liver disease, diabetes, and more. Metabolic syndrome in general, and if you keep it up too much and you may find it’s now a lottery between dying of NAFLD, diabetes, or heart disease (it’ll usually be the heart disease that kills).

See also:

Meanwhile, we know all about the different kinds of nutritional profiles that oils can have, and some can promote having high energy without putting on fat, while others can strain the heart. Not even “a fat is a fat”, so “a calorie is a calorie” doesn’t get much mileage outside of a bomb calorimeter!

See also:

A calorie-controlled / calorie-restricted diet is an effective weight loss strategy: True or False?

True, usually! Surprise!

  • On the one hand: calories are a wildly imprecise way to reckon the value of food, and using them as a guide to health can be dangerously misleading
  • On the other hand: the very activity of calorie-counting itself promotes mindful eating, which is very good for the health

There is a strong difference between the mind of somebody who is carefully logging their pre-bedtime piece of chocolate and reflecting on its nutritional value, vs someone who isn’t sure whether this is their second or third glass of wine, nor how much the glass contained.

So if you want to get most of the benefits of a calorie-controlled diet without counting calories, you may try taking a “mindful eating” approach to diet.

However! If you want to do this for weight loss, be aware, that you will have to practice it all the time, not just for one meal here and there.

  • What is Ryeqo, the recently approved medicine for endometriosis?

    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.

    For women diagnosed with endometriosis it is often a long sentence of chronic pain and cramping that impacts their daily life. It is a condition that is both difficult to diagnose and treat, with many women needing either surgery or regular medication.

    A medicine called Ryeqo has just been approved for marketing specifically for endometriosis, although it was already available in Australia to treat a different condition.

    Women who want the drug will need to consult their local doctor and, as it is not yet on the Pharmaceutical Benefits Scheme, they will need to pay the full cost of the script.

    What does Ryeqo do?

    Endometriosis affects 14% of women of reproductive age. While we don’t have a full understanding of the cause, the evidence suggests it’s due to body tissue that is similar to the lining of the uterus (called the endometrium) growing outside the uterus. This causes pain and inflammation, which reduces quality of life and can also affect fertility.

    Ryeqo is a tablet containing three different active ingredients: relugolix, estradiol and norethisterone.

    Relugolix is a drug that blocks a particular peptide from releasing other hormones. It is also used in the treatment of prostate cancer. Estradiol is a naturally occurring oestrogen hormone in women that helps regulate the menstrual cycle and is used in menopausal hormone therapy. Norethisterone is a synthetic hormone commonly used in birth control medications and to delay menstruation and help with heavy menstrual bleeding.

    All three components work together to regulate the levels of oestrogen and progesterone in the body that contribute to endometriosis, alleviating its symptoms.

    Relugolix reduces the overall levels of oestrogen and progesterone in the body. The estradiol compensates for the loss of oestrogen because low oestrogen levels can cause hot flushes (also called hot flashes) and bone density loss. And norethisterone blocks the effects of estradiol on the uterus (where too much tissue growth is unwanted).

    Is it really new?

    The maker of Ryeqo claims it is the first new drug for endometriosis in Australia in 13 years.

    But individually, all three active ingredients in Ryeqo have been in use since 2019 or earlier.

    Ryeqo has been available in Australia since 2022, but until now was not specifically indicated for endometriosis. It was originally approved for the treatment of uterine fibroids, which share some common symptoms with endometriosis and have related causes.

    In addition to Ryeqo, current medical guidance lists other drugs that are suitable for endometriosis and some reformulations of these have also only been recently approved.

    The oral medicine Dienogest was approved in 2021, and there have been a number of injectable drugs for endometriosis recently approved, such as Sayana Press which was approved in a smaller dose form for self-injection in 2023.

    How to take it and what not to do

    Ryeqo is a once-a-day tablet. You can take it with, or without food, but it should be taken about the same time each day.

    It is recommended you start taking Ryeqo within the first five days after the start of your next period. If you start at another time during your period, you may experience initial irregular or heavier bleeding.

    Because it contains both synthetic and natural hormones, you can’t use the contraceptive pill and Ryeqo together. However, because Ryeqo does contain norethisterone it can be used as your contraception, although it will take at least one month of use to be effective. So, if you are on Ryeqo, you should use a non-hormonal contraceptive – such as condoms – for a month when starting the medicine.

    Ryeqo may be incompatible with other medicines. It might not be suitable for you if you take medicines for epilepsy, HIV and AIDS, hepatitis C, fungal or bacterial infections, high blood pressure, irregular heartbeat, angina (chest pain), or organ rejection. You should also not take Ryeqo if you have a liver tumour or liver disease.

    The possible side effects of Ryeqo are similar to those of oral contraceptives. Blood clots are a risk with any medicine that contains an oestrogen or a progestogen, which Ryeqo does. Other potential side effects include bone loss, a reduction in menstrual blood loss or loss of your period.

    It’s costly for now

    Ryeqo can now be prescribed in Australia, so you should discuss whether Ryeqo is right for you with the doctor you usually consult for your endometriosis.

    While the maker has made a submission to the Pharmaceutical Benefits Advisory Committee, it is not yet subsidised by the Australian government. This means that rather than paying the normal PBS price of up to A$31.60, it has been reported it may cost as much as $135 for a one-month supply. The committee will make a decision on whether to subsidise Ryeqo at its meeting next month.

    Correction: this article has been updated to clarify the recent approval of specific formulations of drugs for endometriosis.The Conversation

  • Fixing Fascia

    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.

    Fascia: Why (And How) You Should Take Care Of Yours

    Fascia is the web-like layer of connective tissue that divides your muscles and organs from each other. It simultaneously holds some stuff in place, and allows other parts to glide over each other with minimal friction.

    At least, that’s what it’s supposed to do.

    Like any body part, it can go wrong. More on this later. But first…

    A quick note on terms

    It may seem like sometimes people say “myofascial” because it sounds fancier, but it does actually have a specific meaning too:

    • Fascia” is what we just described above
    • Myofascial” means “of or relating to muscles and fascia

    For example, “myofascial release” means “stopping the fascia from sticking to the muscle where it shouldn’t” and “myofascial pain” means “pain that has to do with the muscles and fascia”. See also:

    Myofascial vs Fascia: When To Use Each One? What To Consider

    Why fascia is so ignored

    For millennia, it was mostly disregarded as a “neither this nor that” tissue that just happens to be in the body. We didn’t pay attention to it, just like we mostly don’t pay attention to the air around us.

    But, much like the air around us, we sure pay attention when something goes wrong with it!

    However, even in more recent years, we’ve been held back until quite new developments like musculoskeletal ultrasound that could show us problems with the fascia.

    What can go wrong

    It’s supposed to be strong, thin, supple, and slippery. It holds on in the necessary places like a spiderweb, but for the most part, it is evolved for minimum friction.

    Some things can cause it to thicken and become sticky in the wrong places. Things such as:

    • Physical trauma, e.g. an injury or surgery—but we repeat ourselves, because a surgery is an injury! It’s a (usually) necessary injury, but an injury nonetheless.
    • Compensation for pain. If a body part hurts for some reason, and your posture changes to accommodate that, doing so can mess up your fascia, and cause you different problems somewhere else entirely.
      • This is not witchcraft; think of how, when using a corded vacuum cleaner, sometimes the cord can get snagged on something in the next room and we nearly break something because we expected it to just come with us and it didn’t? It’s like that.
    • Repetitive movements (repetitive strain injury is partly a myofascial issue)
    • Not enough movement: when it comes to range of motion, it’s “use it or lose it”.
      • The human body tries its best to be as efficient as possible for us! So eventually it will go “Hey, I notice you never move more than 30º in this direction, so I’m going to stop making fascia that allows you to go past that point, and I’ll just dump the materials here instead”

    “I’ll just dump the materials here instead” is also part of the problem—it creates what we colloquially call “knots”, which are not so much part of the muscle as the fascia that covers it. That’s an actual physical sticky lumpy bit.

    What to do about it

    Firstly, avoid the above things! But, if for whatever reason something has gone wrong and you now have sticky lumpy fascia that doesn’t let you move the way you’d like (if you have any mobility/flexibility issues that aren’t for another known reason, then this is usually it), there are things can be done:

    • Heat—is definitely not a cure-all, but it’s a good first step before doing the other things. A heating pad or a warm bath are great.
    • Massage—ideally, by someone else who knows what they are doing. Self-massage is possible, as is teaching oneself (there are plenty of video tutorials available), but skilled professional therapeutic myofascial release massage is the gold standard.
      • Foam rollers are a great no-skill way to get going with self-massage, whether because that’s what’s available to you, or because you just want something you can do between sessions. Here’s an example of the kind we mean.
    • Acupuncture—triggering localized muscular relaxation, an important part of myofascial release, is something acupuncture is good at.
      • See also: Pinpointing The Usefulness Of Acupuncture ← noteworthily, the strongest criticism of acupuncture for pain relief is that it performs only slightly better than sham acupuncture, but taken in practical terms, all that really means is “sticking little needles in does work, even if not necessarily by the mechanism acupuncturists believe”
    • Calisthenics—Pilates, yoga, and other forms of body movement training can help gradually get one’s fascia to where and how it’s supposed to be.
    • This is that “use it or lose it” bodily efficiency we talked about!

    Remember, the body is always rebuilding itself. It never stops, until you die. So on any given day, you get to choose whether it rebuilds itself a little bit worse or a little bit better.

    Take care!

  • 8 Critical Signs Of Blood Clots That You Shouldn’t Ignore

    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.

    Blood clots can form as part of deep vein thrombosis or for other reasons; wherever they form (unless they are just doing their job healing a wound) they can cause problems. But how to know what’s going on inside our body?

    Telltale signs

    Our usual medical/legal disclaimer applies here, and we are not doctors, let alone your doctors, and even if we were we couldn’t diagnose from afar… But for educational purposes, here are the eight signs from the video:

    • Swelling: especially if only on one leg (assuming you have no injury to account for it), which may feel tight and uncomfortable
    • Warmness: does the area warmer to the touch? This may be because of the body’s inflammatory response trying to deal with a blood clot
    • Tenderness: again, caused by the inflammation in response to the clot
    • Discolored skin: it could be reddish, or bruise-like. This could be patchy or spread over a larger area, because of a clot blocking the flow of blood
    • Shortness of breath: if a clot makes it to the lungs, it can cause extra problems there (pulmonary embolism), and shortness of breath is the first sign of this
    • Coughing up blood: less common than the above but a much more serious sign; get thee to a hospital
    • Chest pain: a sharp or stabbing pain, in particular. The pain may worsen with deep breaths or coughing. Again, seek medical attention.

    For more on recognizing these signs (including helpful visuals), and more on what to do about them and how to avoid them in the first place, enjoy:

    In health terms, we are often about fighting aging here. But to be more specific, what we’re fighting in those cases is not truly aging itself, so much as age-related decline.

    Karen Walrond makes a case that we’ve made from the very start of 10almonds (but she wrote a whole book about it), that there’s merit in looking at what we can and can’t control about aging, doing what we reasonably can, and embracing what we can’t.

    And yes, embracing, not merely accepting. This is not a downer of a book; it’s a call to revolution. It asks us to be proud of our grey hairs, to see our smile-lines around our eyes as the sign of a lived-in body, and even to embrace some of the unavoidable “actual decline” things as part of the journey of life. Maybe we’re not as strong as we used to be and now need a grippety-doodah to open jars; not everyone gets to live long enough to experience that! How lucky we are.

    Perhaps most importantly, she bids us be the change we want to see in the world, and inspire others with our choices and actions, and shake off ageist biases for good.

    Bottom line: if you want to foster a better attitude to aging not only for yourself, but also those around you, then this is a top-tier book for that.

  • Almonds vs Walnuts – Which is Healthier?

    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.

    Our Verdict

    When comparing almonds to walnuts, we picked the almonds.

    Why?

    It wasn’t just our almond bias, but it was close!

    In terms of macros, the main important differences are:

    • Almonds are higher in protein
    • Walnuts are higher in fats (they are healthy fats)

    So far, so even.

    In terms of vitamins, both are rich in many vitamins; mostly the same ones. However, walnuts have more of most of the B vitamins (except for B2 and B3, where almonds win easily), and almonds have more vitamin E by several orders of magnitude.

    So far, so balanced.

    Almonds have slightly more choline.

    Almonds have a better mineral profile, with more of most minerals that they both contain, and especially, a lot more calcium.

    Both nuts have [sometimes slightly different, but] comparable benefits against diabetes, cancer, neurodegeneration, and other diseases.

    In summary

    This one’s close. After balancing out the various “almonds have this but walnuts have that” equal-but-different benefits, we’re going to say almonds take first place by virtue of the better mineral profile, and more choline.

    But: enjoy both!

  • Navigating the health-care system is not easy, but you’re not alone.

    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.

    Hello, dear reader!

    This is my first column for Healthy Debate as a Patient Navigator. This column will be devoted to providing patients with information to help them through their journey with the health-care system and answering your questions.

    Here’s a bit about me: I have been a patient partner at The Ottawa Hospital and Ottawa Hospital Research Institute since 2017, and have joined a variety of governance boards that work on patient and caregiver engagement such as the Patient Advisors Network, the Ontario Health East Region Patient and Family Advisory Council and the Equity in Health Systems Lab.

    My journey as a patient partner started much before 2017 though. When I was a teenager, I was diagnosed with a cholesteatoma, a rare and chronic disease that causes the development of fatty tumors in the middle ear. I have had multiple surgeries to try to fix it but will need regular follow-ups to monitor whether the tumor returns. Because of this, I also live with an invisible disability since I have essentially become functionally deaf in one ear and often rely on a hearing aid when I navigate the world.

    Having undergone three surgeries in my adolescent years, it was my experience undergoing surgery for an acute hand and wrist injury following a jet ski accident as an adult that was the catalyst for my decision to become a patient partner. There was an intriguing contrast between how I was cared for at two different health-care institutions, my age being the deciding factor at which hospital I went to (a children’s hospital or an adult one).

    The most memorable example was how, as a teenager or child, you were never left alone before surgery, and nurses and staff took all the time necessary to comfort me and answer my (and my family’s) questions. I also remember how right before putting me to sleep, the whole staff initiated a surgical pause and introduced themselves and explained to me what their role was during my surgery.

    None of that happened as an adult. I was left in a hallway while the operating theater was prepared, anxious and alone with staff walking by not even batting an eye. My questions felt like an annoyance to the care team; as soon as I was wheeled onto the operating room table, the anesthetist quickly put me to sleep. I didn’t even have the time to see who else was there.

    Now don’t get me wrong: I am incredibly appreciative with the quality of care I received, but it was the everyday interactions with the care teams that I felt could be improved. And so, while I was recovering from that surgery, I looked for a way to help other patients and the hospital improve its care. I discovered the hospital’s patient engagement program, applied, and the rest is history!

    Since then, I have worked on a host of patient-centered policy and research projects and fervently advocate that surgical teams adopt a more compassionate approach with patients before and after surgery.

    I’d be happy to talk a bit more about my journey if you ask, but with that out of the way … Welcome to our first patient navigator column about patient engagement.

    Conceptualizing the continuum of Patient Engagement

    In the context of Canadian health care, patient engagement is a multifaceted concept that involves active collaboration between patients, caregivers, health-care providers and researchers. It involves patients and caregivers as active contributors in decision-making processes, health-care services and medical research. Though the concept is not new, the paradigm shift toward patient engagement in Canada started around 2010.

    I like to conceptualize the different levels of patient engagement as a measure of the strength of the relationship between patients and their interlocutors – whether it’s a healthcare provider, administrator or researcher – charted against the duration of the engagement or the scope of input required from the patient.

    Defining different levels of Patient Engagement

    Following the continuum, let’s begin by defining different levels of patient engagement. Bear in mind that these definitions can vary from one organization to another but are useful in generally labelling the level of patient engagement a project has achieved (or wishes to achieve).

    Patient involvement: If the strength of the relationship between patients and their interlocutors is minimal and not time consuming or too onerous, then perhaps it can be categorized as patient involvement. This applies to many instances of transactional engagement.

    Patient advisory/consulting: Right in the middle of our continuum, patients can find themselves engaging in patient advisory or consulting work, where projects are limited in scope and duration or complexity, and the relationship is not as profound as a partnership.

    Patient partnership: The stronger the relationship is between the patient and their interlocutor, and the longer the engagement activity lasts or how much input the patient is providing, the more this situation can be categorized as patient partnership. It is the inverse of patient involvement.

    Examples of the different levels of Patient Engagement

    Let’s pretend you are accompanying a loved one to an appointment to manage a kidney disease, requiring them to undergo dialysis treatment. We’ll use this scenario to exemplify what label could be used to describe the level of engagement.

    Patient involvement: In our case, if your loved one – or you – fills out a satisfaction or feedback survey about your experience in the waiting room and all that needed to be done was to hand it back to the clerk or care team, then, at a basic level, you could likely label this interaction as a form of patient involvement. It can also involve open consultations around a design of a new look and feel for a hospital, or the understandability of a survey or communications product. Interactions with the care team, administrators or researchers are minimal and often transactional.

    Patient advisory/consulting: If your loved one was asked for more detailed information about survey results over the course of a few meetings, this could represent patient advisory/consulting. This could mean that patients meet with program administrators and care providers and share their insights on how things can be improved. It essentially involves patients providing advice to health-care institutions from the perspective of patients, their family members and caregivers.

    Patient advisors or consultants are often appointed by hospitals or academic institutions to offer insights at multiple stages of health-care delivery and research. They can help pilot an initiative based on that feedback or evaluate whether the new solutions are working. Often patient advisors are engaged in smaller-term individual projects and meet with the project team as regularly as required.

    Patient partnership: Going above and beyond patient advisory, if patients have built a trusting relationship with their care team or administrators, they could feel comfortable enough to partner with them and initiate a project of their own. This could be for a project in which they study a different form of treatment to improve patient-centered outcomes (like the time it takes to feel “normal” following a session); it could be working together to identify and remove barriers for other patients that need to access that type of care. These projects are not fulfilled overnight, but require a collaborative, longstanding and trusting relationship between patients and health-care providers, administrators or researchers. It ensures that patients, regardless of severity or chronicity of their illness, can meaningfully contribute their experiences to aid in improving patient care, or develop or implement policies, pilots or research projects from start to finish.

    It is leveraging that lived and living experience to its full extent and having the patient partner involved as an equal voice in the decision-making process for a project – over many months, usually – that the engagement could be labeled a partnership.

    Last words

    The point of this column will be to answer or explore issues or questions related to patient engagement, health communications or even provide some thoughts on how to handle a particular situation.

    I would be happy to collect your questions and feedback at any time, which will help inform future columns. Just email me at [email protected] or connect with me on social media (Linked In, X / Twitter).
