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.

Managing Jealousy
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.
Jealousy is often thought of as a young people’s affliction, but it can affect us at any age—whether we are the one being jealous, or perhaps a partner.
And, the “green-eyed monster” can really ruin a lot of things; relationships, friendships, general happiness, physical health even (per stress and anxiety and bad sleep), and more.
The thing is, jealousy looks like one thing, but is actually mostly another.
Jealousy is a Scooby-Doo villain
That is to say: we can unmask it and see what much less threatening thing is underneath. Which is usually nothing more nor less than: insecurities
- Insecurity about losing one’s partner
- Insecurity about not being good enough
- Insecurity about looking bad socially
…etc. The latter, by the way, is usually the case when one’s partner is socially considered to be giving cause for jealousy, but the primary concern is not actually relational loss or any kind of infidelity, but rather, looking like one cannot keep one’s partner’s full attention romantically/sexually. This drives a lot of people to act on jealousy for the sake of appearances, in situations where they might otherwise, if they didn’t feel like they’d be adversely judged for it, be considerably more chill.
Thus, while monogamy certainly has its fine merits, there can also be a kind of “toxic monogamy” at hand, where a relationship becomes unhealthy because one partner is just trying to live up to social expectations of keeping the other partner in check.
This, by the way, is something that people in polyamorous and/or open relationships typically handle quite neatly, even if a lot of the following still applies. But today, we’re making the statistically safe assumption of a monogamous relationship, and talking about that!
How to deal with the social aspect
If you sit down with your partner and work out in advance the acceptable parameters of your relationship, you’ll be ahead of most people already. For example…
- What counts as cheating? Is it all and any sex acts with all and any people? If not, where’s the line?
- What about kissing? What about touching other body parts? If there are boundaries that are important to you, talk about them. Nothing is “too obvious” because it’s astonishing how many times it will happen that later someone says (in good faith or not), “but I thought…”
- What about being seen in various states of undress? Or seeing other people in various states of undress?
- Is meaningless flirting between friends ok, and if so, how do we draw the line with regard to what is meaningless? And how are we defining flirting, for that matter? Talk about it and ensure you are both on the same page.
- If a third party is possibly making moves on one of us under the guise of “just being friendly”, where and how do we draw the line between friendliness and romantic/sexual advances? What’s the difference between a lunch date with a friend and a romantic meal out for two, and how can we define the difference in a way that doesn’t rely on subjective “well I didn’t think it was romantic”?
If all this seems like a lot of work, please bear in mind, it’s a lot more fun to cover this cheerfully as a fun couple exercise in advance, than it is to argue about it after the fact!

How to deal with the more intrinsic insecurities
For example, when jealousy is a sign of a partner fearing not being good enough, not measuring up, or perhaps even losing their partner.
The key here might not shock you: communication
Specifically, reassurance. But critically, the correct reassurance!
A partner who is jealous will often seek the wrong reassurance, for example wanting to read their partner’s messages on their phone, or things like that. And while a natural desire when experiencing jealousy, it’s not actually helpful. Because while incriminating messages could confirm infidelity, it’s impossible to prove a negative, and if nothing incriminating is found, the jealous partner can just go on fearing the worst regardless. After all, their partner could have a burner phone somewhere, or a hidden app for cheating, or something else like that. So, no reassurance can ever be given/gained by such requests (which can also become unpleasantly controlling, which hopefully nobody wants).
A quick note on “if you have nothing to fear, you have nothing to hide”: rhetorically that works, but practically it doesn’t.
Writer’s example: when my late partner and I formalized our relationship, we discussed boundaries, and I expressed “so far as I am concerned, I have no secrets from you, except secrets that are not mine to share. For example, if someone has confided in me and asked that I not share it, I won’t. Aside from that, you have access-all-areas in my life; me being yours has its privileges” and this policy itself would already pre-empt any desire to read my messages. Now indeed, I had nothing to hide. I am by character devoted to a fault. But my friends may well sometimes have things they don’t want me to share, which made that a necessary boundary to highlight (which my partner, an absolute angel by the way and not overly prone to jealousy in any case, understood completely).
So, it is best if the partner of a jealous person can explain the above principles as necessary, and offer the correct reassurance instead. Which could be any number of things, but for example:
- I am yours, and nobody else has a chance
- I fully intend to stay with you for life
- You are the best partner I have ever had
- Being with you makes my life so much better
…etc. Note that none of these are “you don’t have to worry about so-and-so”, or “I am not cheating on you”, etc, because it’s about yours and your partner’s relationship. If they ask for reassurances with regard to other people or activities, by all means state them as appropriate, but try to keep the focus on you two.
And if your partner (or you, if it’s you who’s jealous) can express the insecurity in the format…
“I’m afraid of _____ because _____”
…then the “because” will allow for much more specific reassurance. We all have insecurities, we all have reasons we might fear not being good enough for our partner, or losing their affection, and the best thing we can do is choose to trust our partners at least enough to discuss those fears openly with each other.
See also: Save Time With Better Communication ← this can avoid a lot of time-consuming arguments
What about if the insecurity is based in something demonstrably correct?
By this we mean, something like a prior history of cheating, or other reasons for trust issues. In such a case, the jealous partner may well have a reason for their jealousy that isn’t based on a personal insecurity.
In our previous article about boundaries, we talked about relationships (romantic or otherwise) having a “price of entry”. In this case, you each have a “price of entry”:
- The “price of entry” to being with the person who has previously cheated (or similar), is being able to accept that.
- And for the person who cheated (or similar), very likely their partner will have the “price of entry” of “don’t do that again, and also meanwhile accept in good grace that I might be jittery about it”.
And, if the betrayal of trust was something that happened between the current partners in the current relationship, most likely that was also traumatic for the person whose trust was betrayed. Many people in that situation find that trust can indeed be rebuilt, but slowly, and the pain itself may also need treatment (such as therapy and/or couples therapy specifically).

Apple Cider Vinegar vs Balsamic Vinegar – 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 apple cider vinegar to balsamic vinegar, we picked the apple cider vinegar.
Why?
It’s close! And it’s a simple one today and they’re both great. Taking either for blood-sugar-balancing benefits is fine, as it’s the acidity that has this effect. But:
- Of the two, balsamic vinegar is the one more likely to contain more sugars, especially if it’s been treated in any fashion, and not by you, e.g. made into a glaze or even a reduction (the latter has no need to add sugar, but sometimes companies do because it is cheaper—so we recommend making your own balsamic vinegar reduction at home)
- Of the two, apple cider vinegar is the one more likely to contain “the mother”, that is to say, the part with extra probiotic benefits (but if the vinegar has been filtered, it won’t have this—it’s just more common to be able to find unfiltered apple cider vinegar, since it has more popular attention for its health benefits than balsamic vinegar does)
So, two wins for apple cider vinegar there.

Behavioral Activation Against Depression & Anxiety

Behavioral Activation Against Depression & Anxiety
Psychologists do love making fancy new names for things.
You thought you were merely “eating your breakfast”, but now it’s “Happiness-Oriented Basic Behavioral Intervention Therapy (HOBBIT)” or something.
This one’s quite simple, so we’ll keep it short for today, but it is one more tool for your toolbox:
What is Behavioral Activation?
Behavioral Activation is about improving our mood (something we can’t directly choose) by changing our behavior (something we usually can directly choose).
An oversimplified (and insufficient, as we will explain, but we’ll use this one to get us started) example would be “whistle a happy tune and you will be happy”.
Behavioral Activation is not a silver bullet
Or if it is, then it’s the kind you have to keep shooting, because one shot is not enough. However, this becomes easier than you might think, because Behavioral Activation works by…
Creating a Positive Feedback Loop
A lot of internal problems in depression and anxiety are created by the fact that necessary and otherwise desirable activities are being written off by the brain as:
- Pointless (depression)
- Dangerous (anxiety)
The inaction that results from these aversions creates a negative feedback loop as one’s life gradually declines (as does one’s energy, and interest in life), or as the outside world seems more and more unwelcoming/scary.
Instead, Behavioral Activation plans activities (usually with the help of a therapist, as depressed/anxious people are not the most inclined to plan activities) that will be:
- attainable
- rewarding
The first part is important, because the maximum of what is “attainable” to a depressed/anxious person can often be quite a small thing. So, small goals are ideal at first.
The second part is important, because there needs to be some way of jump-starting a healthier dopamine cycle. It also has to feel rewarding during/after doing it, not next year, so short term plans are ideal at first.
So, what behavior should we do?
That depends on you. Behavioral Activation calls for keeping track of our activities (bullet-journaling is fine, and there are apps* that can help you, too) and corresponding moods.
*This writer uses the pragmatic Daylio for its nice statistical analyses of bullet-journaling data-points, and the very cute Finch for more keyword-oriented insights and suggestions. Whatever works for you, works for you, though! It could even be paper and pen.
Sometimes the very thought of an activity fills us with dread, but the actual execution of it brings us relief. Bullet-journaling can track that sort of thing, and inform decisions about “what we should do” going forwards.

Here’s list of activities suggested by TherapistAid (a resource hub for therapists)

The Epigenetics Revolution – by Dr. Nessa Carey
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.
If you enjoyed the book “Inheritance” that we reviewed a couple of days ago, you might love this as a “next read” book. But you can also just dive straight in here, if you like!
This one, as the title suggests, focuses entirely on epigenetics—how our life events can shape our genetic expression, and that of our descendants. Or to look at it in the other direction, how our genetic expression can be shaped by the life experiences of, for example, our grandparents.
The style of this book is very much pop-science, but contains a lot of information from hard science throughout. We learn not just about longitudinal population studies as one might expect, but also about the intricacies of DNA methylation and histone modifications, for example.
Depending on your outlook, you may find some of this very bleak (“great, I am shackled by what my grandparents did”) or very optimism-inducing (“oh wow, I’m not nearly so constrained by genetics as I thought; this stuff is so malleable!”). This is also the same author who wrote “Hacking The Code of Life“, by the way, but we’ll review that another day.
Bottom line: this book is the best one-shot primer on epigenetics that this reviewer has read (you may be wondering how many that is, and the answer is… about seven or so? I’m not good at counting).

Walnuts vs Brazil Nuts – 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 walnuts to Brazil nuts, we picked the walnuts.
Why?
Talking macros first, they are about equal in protein, carbs, fats, and fiber; their composition is almost identical in this regard. However, looking a little more closely at the fats, Brazil nuts have more than 2x the saturated fat, while walnuts have nearly 2x the polyunsaturated fat. So, we’ll declare the macros category a moderate win for walnuts.
The category of vitamins is not balanced; walnuts have more of vitamins A, B2, B3, B5, B6, B9, C, and choline, while Brazil nuts have more of vitamins B1 and E. A clear and easy win for walnuts.
The category of minerals is interesting, because of one mineral in particular. First let’s mention: walnuts have more iron and manganese, while Brazil nuts have more calcium, copper, magnesium, phosphorus, potassium, and selenium. Taken at face value, this is a clear win for Brazil nuts. However…
About that selenium… Specifically, it’s more than 391x higher, and a cup of Brazil nuts would give nearly 10,000x the recommended daily amount of selenium. Now, selenium is an essential mineral (needed for thyroid hormone production, for example), and at the RDA it’s good for good health. Your hair will be luscious and shiny. However, go much above that, and selenium toxicity becomes a thing, you may get sick, and it can cause your (luscious and shiny) hair to fall out. For this reason, it’s recommended to eat no more than 3–4 Brazil nuts per day.
There is one last consideration, and this is oxalates; walnuts are moderately high in oxalates (>50mg/100g) while Brazil nuts are very high in oxalates (>500mg/100g). This won’t affect most people at all, but if you have pre-existing kidney problems (including a history of kidney stones), you might want to go easy on oxalate-containing foods.
For most people, however, walnuts are a very healthy choice, and outshine Brazil nuts in most ways.

The Dark Side Of Memory (And How To Make Your Life Better)
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 Stop Revisiting Those Memories
We’ve talked before about putting the brakes on negative thought spirals (and that’s a really useful technique, so if you weren’t with us yet for that one, we do recommend hopping back and reading it!).
We’ve also talked about optimizing memory, to include making moments unforgettable.
But what about the moments we’d rather forget?
First, a quick note: we have no pressing wish or need to re-traumatize any readers, so if you’ve a pressing reason to think your memories you’d rather forget are beyond the scope of a few hundred words “one quick trick” in a newsletter, feel free to skip this section today.
One more quick note: it is generally not considered healthy to repress important memories. Some things are best worked through consciously in therapy with a competent professional.
Today’s technique is more for things in the category of “do you really need to keep remembering that one time you did something embarrassing 20 years ago?”
That said… sometimes, even when it does come to the management of serious PTSD, therapy can (intentionally, reasonably) throw in the towel on processing all of something big, and instead seek to simply look at minimizing its effect on ongoing life. Again, that’s best undertaken with a well-trained professional, however.
For more trivial annoyances, meanwhile…
Two Steps To Forgetting
The first step:
You may remember that memories are tied to the senses, and the more senses are involved, the more easily and fully we remember a thing. To remember something, therefore, we make sure to pay full attention to all the sensory experience of the memory, bringing in all 5 senses if possible.
To forget, the reverse is true. Drain the memory of color, make it black and white, fuzzier, blurrier, smaller, further away, sterile, silent, gone.
You can make a habit of doing this automatically whenever your unwanted memory resurfaces.
The
secondmissing step:This is the second step, but it’s going to be a missing step. Memories, like paths in a forest, are easier to access the more often we access them. A memory we visit every day will have a well-worn path, easy to follow. A memory we haven’t visited for decades will have an overgrown, sometimes nearly impossible-to-find path.
To labor the metaphor a little: if your memory has literal steps leading to it, we’re going to remove one of the steps now, to make it very difficult to access accidentally. Don’t worry, you can always put the step back later if you want to.
Let’s say you want to forget something that happened once upon a time in a certain workplace. Rather than wait for the memory in question to come up, we’re going to apply the first step that we just learned, to the entire workplace.
So, in this example, you’d make the memory of that workplace drained of color, made black and white, fuzzier, blurrier, smaller, further away, sterile, silent, gone.
Then, you’d make a habit of doing that whenever that workplace nearly comes to mind.
The result? You’re unlikely to accidentally access a memory that occurred in that workplace, if even mentally wandering to the workplace itself causes it to shrivel up and disappear like paper in fire.
Important reminder
The above psychological technique is to psychological trauma what painkillers are to physical pain. It can ease the symptom, while masking the cause. If it’s something serious, we recommend enlisting the help of a professional, rather than “self-medicating” in this fashion.
If it’s just a small annoying thing, though, sometimes it’s easier to just be able to refrain from prodding and poking it daily, forget about it, and enjoy life.
