Protein vs Sarcopenia
This is Dr. Gabrielle Lyon. A medical doctor, she’s board-certified in family medicine, and has also engaged in research and clinical practice in the fields of geriatrics and nutritional sciences.
A quick note…
We’re going to be talking a bit about protein metabolism today, and it’s worth noting that Dr. Lyon personally is vehemently against vegetarianism/veganism, and considers red meat to be healthy.
Scientific consensus on the other hand, holds that vegetarianism and veganism are fine for most people if pursued in an informed and mindful fashion, that white meat and fish are also fine for most people, and red meat is simply not.
If you’d like a recap on the science of any of that:
- Protein: How Much Do We Need, Really?
- Plant vs Animal Protein: Diversity is Key
- Do We Need Animal Products to be Healthy?
Nevertheless, if we look at the science that she provides, the advice is sound when applied to protein in general and without an undue focus on red meat.
How much protein is enough?
In our article linked above, we gave 1–2g/kg/day
Dr. Lyons gives the more specific 1.6g/kg/day for adults older than 40 (this is where sarcopenia often begins!) and laments that many sources offer 0.8g/kg.
To be clear, that “per kilogram” means per kilogram of your bodyweight. For Americans, this means dividing lbs by 2.2 to get the kg figure.
Why so much protein?
Protein is needed to rebuild not just our muscles, but also our bones, joint tissues, and various other parts of us:
We Are Such Stuff As Fish Are Made Of
Additionally, our muscles themselves are important for far more than just moving us (and other things) around.
As Dr. Lyon explains: sarcopenia, the (usually age-related) loss of muscle mass, does more than just make us frail; it also messes up our metabolism, which in turn messes up… Everything else, really. Because everything depends on that.
This is because our muscles themselves use a lot of our energy, and/but also store energy as glycogen, so having less of them means:
- getting a slower metabolism
- the energy that can’t be stored in muscle tissue gets stored somewhere else (like the liver, and/or visceral fat)
So, while for example the correlation between maintaining strong muscles and avoiding non-alcoholic fatty liver disease may not be immediately obvious, it is clear when one follows the metabolic trail to its inevitable conclusion.
Same goes for avoiding diabetes, heart disease, and suchlike, though those things are a little more intuitive.
How can we get so much protein?
It can seem daunting at first to get so much protein if you’re not used to it, especially as protein is an appetite suppressant, so you’ll feel full sooner.
It can especially seem daunting to get so much protein if you’re trying to avoid too many carbs, and here’s where Dr. Lyon’s anti-vegetarianism does have a point: it’s harder to get lean protein without meat/fish.
That said, “harder” does not mean “impossible” and even she acknowledges that lentils are great for this.
If you’re not vegetarian or vegan, collagen supplementation is a good way to make up any shortfall, by the way.
And for everyone, there are protein supplements available if we want them (usually based on whey protein or soy protein)
Anything else we need to do?
Yes! Eating protein means nothing if you don’t do any resistance work to build and maintain muscle. This can take various forms, and Dr. Lyon recommends lifting weights and/or doing bodyweight resistance training (calisthenics, Pilates, etc).
Here are some previous articles of ours, consistent with the above:

The Worst Way to Wake Up (and What to Do Instead)
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.
Not everyone is naturally inclined to be a morning person, but there are things we can do to make things go more easily for our brains!
Cause for alarm?
Dr. Tracey Marks, psychiatrist, explains the impact of our first moments upon awakening, and what that can do to/for us in terms of sleep inertia (i.e. grogginess).
Sleep inertia is worse when waking from deep sleep—and notably, we don’t naturally wake directly from deep sleep unless we are externally aroused (e.g. by an alarm clock).
Dr. Marks suggests the use of more gradual alarms, including those with soft melodies, perhaps birdsong or other similarly gentle things (artificial sunlight alarms are also good), to ease our transition from sleeping to waking. It might take us a few minutes longer to be woken from sleep, but we’re not going to spend the next hour in a bleary-eyed stupor.

Vaccines and cancer: The myth that won’t die
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.
Two recent studies reported rising cancer rates among younger adults in the U.S. and worldwide. This prompted some online anti-vaccine accounts to link the studies’ findings to COVID-19 vaccines.
But, as with other myths, the data tells a very different story.
What you need to know
- Baseless claims that COVID-19 vaccines cause cancer have persisted online for several years and gained traction in late 2023.
- Two recent reports finding rising cancer rates among younger adults are based on pre-pandemic cancer incidence data. Cancer rates in the U.S. have been on the rise since the 1990s.
- There is no evidence of a link between COVID-19 vaccination and increased cancer risk.
False claims about COVID-19 vaccines began circulating months before the vaccines were available. Chief among these claims was misinformed speculation that vaccine mRNA could alter or integrate into vaccine recipients’ DNA.
It does not. But that didn’t prevent some on social media from spinning that claim into a persistent myth alleging that mRNA vaccines can cause or accelerate cancer growth. Anti-vaccine groups even coined the term “turbo cancer” to describe a fake phenomenon of abnormally aggressive cancers allegedly linked to COVID-19 vaccines.
They used the American Cancer Society’s 2024 cancer projection—based on incidence data through 2020—and a study of global cancer trends between 1999 and 2019 to bolster the false claims. This exposed the dishonesty at the heart of the anti-vaccine messaging, as data that predated the pandemic by decades was carelessly linked to COVID-19 vaccines in viral social media posts.
Some on social media cherry-pick data and use unfounded evidence because the claims that COVID-19 vaccines cause cancer are not true. According to the National Cancer Institute and American Cancer Society, there is no evidence of any link between COVID-19 vaccines and an increase in cancer diagnosis, progression, or remission.
Why does the vaccine cancer myth endure?
At the root of false cancer claims about COVID-19 vaccines is a long history of anti-vaccine figures falsely linking vaccines to cancer. Polio and HPV vaccines have both been the target of disproven cancer myths.
Not only do HPV vaccines not cause cancer, they are one of only two vaccines that prevent cancer.
In the case of polio vaccines, some early batches were contaminated with simian virus 40 (SV40), a virus that is known to cause cancer in some mammals but not humans. The contaminated batches were discovered, and no other vaccine has had SV40 contamination in over 60 years.
Follow-up studies found no increase in cancer rates in people who received the SV40-contaminated polio vaccine. Yet, vaccine opponents have for decades claimed that polio vaccines cause cancer.
Recycling of the SV40 myth
The SV40 myth resurfaced in 2023 when vaccine opponents claimed that COVID-19 vaccines contain the virus. In reality, a small, nonfunctional piece of the SV40 virus is used in the production of some COVID-19 vaccines. This DNA fragment, called the promoter, is commonly used in biomedical research and vaccine development and doesn’t remain in the finished product.
Crucially, the SV40 promoter used to produce COVID-19 vaccines doesn’t contain the part of the virus that enters the cell nucleus and is associated with cancer-causing properties in some animals. The promoter also lacks the ability to survive on its own inside the cell or interact with DNA. In other words, it poses no risk to humans.
Over 5.6 billion people worldwide have received COVID-19 vaccines since December 2020. At that scale, even the tiniest increase in cancer rates in vaccinated populations would equal hundreds of thousands of excess cancer diagnoses and deaths. The evidence for alleged vaccine-linked cancer would be observed in real incidence, treatment, and mortality data, not social media anecdotes or unverifiable reports.

Forever Strong – by Dr. Gabrielle Lyon
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.
Obesity kills a lot of people (as does medical neglect and malpractice when it comes to obese patients, but that is another matter), but often the biggest problem is not “too much fat” but rather “too little muscle”. This gets disguised a bit, because these factors often appear in the same people, but it’s a distinction that’s worthy of note.
Dr. Lyon lays out a lot of good hard science in this work, generally in the field of protein metabolism, but also with a keen eye on all manner of blood metrics (triglycerides, LDL/HDL, fasting blood sugars, assorted other biomarkers of metabolic health).
The style of this book is two books in one. It’s a very accessible pop-science book in its primary tone, with an extra layer of precise science and lots of references, for those who wish to dive into that.
In the category of criticism, the diet plan section of the book is rather meat-centric, but the goal of this is protein content, not meat per se, so substitutions can easily be made. That’s just one small section of the book, though, and it’s little enough a downside that even Dr. Mark Hyman (a popular proponent of plant-based nutrition) highly recommends the book.
Bottom line: if you’d like to be less merely fighting decline and more actually becoming healthier as you age, then this book will help you do just that.

Antioxidant Matcha Snack Bars
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 antioxidants in this come not just from the matcha, but also the cacao nibs and chocolate, as well as lots of nutrients from the hazelnuts and cashews. If you’re allergic to nuts, we’ll give you substitutions that will change the nutritional profile (and flavor), but still work perfectly well and be healthy too.
You will need
For the base:
- ⅔ cup roasted hazelnuts (if allergic, substitute dessicated coconut)
- ⅔ cup chopped dates
For the main part:
- 1 cup raw cashews (if allergic, substitute raw coconut, chopped)
- ½ cup almond milk (or your preferred milk of any kind)
- ½ cup cacao nibs
- 2 tbsp lime juice
- 1 tbsp matcha powder
- 1 tbsp maple syrup (omit if you don’t care for sweetness)
For the topping (optional):
- 2oz dark chocolate, melted (and if you like, tempered—but this isn’t necessary; it’ll just make it glossier if you do)
- Spare cacao nibs, chopped nuts, or anything else you might want on there
Method
(we suggest you read everything at least once before doing anything)
1) Blend the base ingredients in a food processor until it has a coarse sticky texture, but isn’t yet a paste or dough.
2) Line a cake pan with baking paper and spread the base mix on the base; press it down to compact it a little and ensure it is flat. If there’s room, put this in the freezer while you do the next bit. If not, the fridge will suffice.
3) Blend the main part ingredients apart from the cacao nibs, until smooth. Stir in the cacao nibs with a spoon.
4) Spread the main part evenly over the base, and allow everything you’ve built (in this recipe, not in life in general) to chill in the fridge for at least 4 hours.
5) Cut it into blocks of the size and shape you want to eat them, and (if adding the optional topping) separate the blocks slightly from each other, before drizzling with the chocolate topping. Put it back in the fridge to cool this too; an hour should be sufficient.
6) Serve!
Enjoy!

Why Adult ADHD Often Leads To Anxiety & Depression
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.
ADHD’s Knock-On Effects On Mental Health
We’ve written before about ADHD in adult life, often late-diagnosed because it’s not quite what people think it is:
In women in particular, it can get missed and/or misdiagnosed:
Miss Diagnosis: Anxiety, ADHD, & Women
…but what we’re really here to talk about today is:
It’s the comorbidities that get you
When it comes to physical health conditions:
- if you have one serious condition, it will (usually) be taken seriously
- if you have two, they will still be taken seriously, but people (friends and family members, as well as yes, medical professionals) will start to back off, as it starts to get too complicated for comfort
- if you have three, people will think you are making at least one of them up for attention now
- if you have more than three, you are considered a hypochondriac and pathological liar
Yet, the reality is: having one serious condition increases your chances of having others, and this chance-increasing feature compounds with each extra condition.
Illustrative example: you have fibromyalgia (ouch) which makes it difficult for you to exercise much, shop around when grocery shopping, and do much cooking at home. You do your best, but your diet slips and it’s hard to care when you just want the pain to stop; you put on some weight, and get diagnosed with metabolic syndrome, which in time becomes diabetes with high cardiovascular risk factors. Your diabetes is immunocompromising; you get COVID and find it’s now Long COVID, which brings about Chronic Fatigue Syndrome, when you barely had the spoons to function in the first place. At this point you’ve lost count of conditions and are just trying to get through the day.
If this is you, by the way, we hope at least something in the following might ease things for you a bit:
- Stop Pain Spreading
- Managing Chronic Pain (Realistically!)
- Eat To Beat Chronic Fatigue (While Having The Limitations Of Chronic Fatigue)
- When Painkillers Aren’t Helping, These Things Might
- The 7 Approaches To Pain Management
It’s the same for mental health
In the case of ADHD as a common starting point (because it’s quite common, may or may not be diagnosed until later in life, and doesn’t require any external cause to appear), it is very common that it will lead to anxiety and/or depression, to the point that it’s perhaps more common to also have one or more of them than not, if you have ADHD.
(Of course, anxiety and/or depression can both pop up for completely unrelated reasons too, and those reasons may be physiological, environmental, or a combination of the above).
Why?
Because all the good advice that goes for good mental health (and/or life in general), gets harder to actuate when one had ADHD.
- “Strong habits are the core of a good life”, but good luck with that if your brain doesn’t register dopamine in the same way as most people’s do, making intentional habit-forming harder on a physiological level.
- “Plan things carefully and stick to the plan”, but good luck with that if you are neurologically impeded from forming plans.
- “Just do it”, but oops you have the tendency-to-overcommitment disorder and now you are seriously overwhelmed with all the things you tried to do, when each of them alone were already going to be a challenge.
Overwhelm and breakdown are almost inevitable.
And when they happen, chances are you will alienate people, and/or simply alienate yourself. You will hide away, you will avoid inflicting yourself on others, you will brood alone in frustration—or distract yourself with something mind-numbing.
Before you know it, you’re too anxious to try to do things with other people or generally show your face to the world (because how will they react, and won’t you just mess things up anyway?), and/or too depressed to leave your depression-lair (because maybe if you keep playing Kingdom Vegetables 2, you can find a crumb of dopamine somewhere).
What to do about it
How to tackle the many-headed beast? By the heads! With your eyes open. Recognize and acknowledge each of the heads; you can’t beat those heads by sticking your own in the sand.
Also, get help. Those words are often used to mean therapy, but in this case we mean, any help. Enlist your partner or close friend as your support in your mental health journey. Enlist a cleaner as your support in taking that one thing off your plate, if that’s an option and a relevant thing for you. Set low but meaningful goals for deciding what constitutes “good enough” for each life area. Decide in advance what you can safely half-ass, and what things in life truly require your whole ass.
Here’s a good starting point for that kind of thing:
When You Know What You “Should” Do (But Knowing Isn’t The Problem)

When And Why Do We Pick Up Our Phones?
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 School of Life’s Alain de Botton makes the argument that—if we pay attention, if we keep track—there’s an understory to why we pick up our phones:
It’s not about information
Yes, our phones (or rather, the apps therein) are designed to addict us, to draw us back, to keep us scrolling and never let us go. We indeed seek out information like our ancestors once sought out berries; searching, encouraged by a small discovery, looking for more. The neurochemistry is similar.
But when we look at the “when” of picking up our phones, de Botton says, it tells a different story:
We pick them up not to find out what’s going on with the world, but rather specifically to not find out what’s going with ourselves. We pick them up to white out some anxiety we don’t want to examine, a line of thought we don’t want to go down, memories we don’t want to consider, futures we do not want to have to worry about.
And of course, phones do have a great educational potential, are an immensely powerful tool for accessing knowledge of many kinds—if only we can remain truly conscious while using them, and not take them as the new “opiate of the masses”.
De Botton bids us, when next we pick up our phone. ask a brave question:
“If I weren’t allowed to consult my phone right now, what might I need to think about?”
