Science of HIIT – by Ingrid Clay

We previously reviewed another book in this series, Science of Yoga. This one’s about HIIT: High Intensity Interval Training!
We’ve written about HIIT before too, but our article doesn’t have the same amount of room as a book, so…
This one lays out 90 key HIIT exercises that you can do at home without special equipment. By “without special equipment”, we mean: there are a few exercises that use dumbbells, but if you don’t want to get/use dumbbells, you can improvize (e.g. with water bottles as weights) or skip those. All the rest require just your body!
The illustrations are clear and the explanations excellent. The book also dives into (as the title promises) the science of HIIT, and why it works the way it does to give results that can’t be achieved with other forms of exercise.
Bottom line: if you’ve been wanting to do HIIT but have not yet found a way of doing it that suits your lifestyle, this book gives many excellent options.

The Brain Health Book – by Dr. John Randolph
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 author, a clinical neuropsychologist and brain health consultant, brings his professional knowledge and understanding to bear on the questions of what works, what doesn’t, and why?
In practical terms, the focus is mostly on maintaining/improving attention, memory, and executive functions. To that end, he covers what kinds of exercises to do (physical and mental!), and examines what strategies make the most difference—including the usual lifestyle considerations of course, but also more specifically than that, what to prioritize over what when it comes to daily choices.
The style is easy pop-science, with an emphasis on being directly useful to the reader, rather than giving an overabundance of citations for everything as we go along. He does, however, explain the necessary science as we go, making the book educational without being academic.
Bottom line: if you’d like to maintain/improve your brain, this book can certainly help with that, and as a bonus (unless you are already an expert) you’ll learn plenty about the brain as you go.

❝Does anything actually get rid of cellulite? Nothing seems to❞
Let’s get the bad news over with in one go:
Nothing (that the scientific world currently knows of) can get rid of cellulite permanently, nor completely guard against it proactively. Which, given that it affects up to 98% of women to some degree, and often shows up not long after puberty (though it can appear at any time and often increases later in life), any pre-emptive health regime would need to be started as a child in any case.
As with many things that predominantly affect women, the world of medicine isn’t entirely sure what causes it, let alone how to effectively treat it.
Obviously hormones are implicated, namely estrogen.
Obviously adiposity is implicated, because one can’t have dimples in one’s fat if one doesn’t have enough fat to dimple.
Other hypothesized contributory factors include genetics, poor diet, inactivity, unhealthy lifestyle (in ways not previously mentioned, e.g. use of alcohol, tobacco, etc), accumulated toxins, and pregnancy.
Here’s an old paper (from 2004); today’s reviews say pretty much the same thing, but we love how succinctly (albeit, somewhat depressingly) this abstract states how little we know and how little we can do:
Cellulite: a review of its physiology and treatment
However, all is not lost!
There are some things that can affect how much cellulite we get, and there are some things that can reduce it, and even some things that can get rid of it completely—albeit temporarily.
First, a quick refresher on what it actually is, physiologically speaking: cellulite occurs when connective tissue bands pull the skin down in places, where fat tissue has been able to squeeze through. One of the reasons it is hypothesized women get this more than men is because our fat is not merely different in distribution and overall percentage, but also in how the fat cells stack up; we generally have have of a vertical stacking structure going on, while men generally have a more horizontal structure. This means that it can be easier for ours to get moved about differently, causing the connective tissue to pull on the skin unevenly in places.
With that in mind…
Prevention is, as we say, probably impossible if your body is running on estrogen. However, those contributory factors we mentioned above? Most of those are modifiable, including these things that it is hypothesized can reduce it:
Diet: as it seems to be worsened by inflammation (what isn’t?), an anti-inflammatory diet is recommended.
Exercise: there are three things here: 1) exercises to improve circulation and thus the body’s ability to sort things out by itself 2) HIIT exercise to reduce body fat percentage, if one has a high enough starting body fat percentage for that to be a healthy goal 3) mobility exercises, to ensure our connective tissues are the right amount of mobile.
Creams and lotions
These reduce the superficial appearance of cellulite, without actually treating the thing itself. Mostly they are caffeine-based, which when used topically increases blood flow and works as a local diuretic, reducing the water content of the fat cells, diminishing the appearance of the cellulite by making each fat cell physically smaller (while still containing the same amount of fat, and it’ll bounce back in size as soon as the body can restore osmotic balance).
Medical procedures
There are too many of these to discuss them all separately, but they all work on the principle of breaking up the tough bands of connective tissue to eliminate the dimpling of cellulite.
The methods they use vary from ultrasound to cryolipolysis to lasers to “vacuum-assisted precise tissue release”, which involves a suction pump and a multipronged robotic assembly with needles to administer anaesthetic as it goes and small blades to cut the connective tissues under the skin:
Tissue Stabilized–Guided Subcision for the Treatment of Cellulite
That last one definitely sounds like the least fun, but it’s also the only one that doesn’t take months to maybe see results.
Cellulite can and almost certainly will come back after all of these.
Home remedies
Aside from at-home versions of the above (not the robots with vacuum pumps and needles and microblades, hopefully, but for example homemade caffeine creams), and of course diet and exercise which can be considered “home remedies”, there are two more things worth mentioning:
Dry brushing: using a body brush to, as the name suggests, simply brush one’s skin. The “dry” aspect here is simply that it’s not done in the bath or shower; it’s done while dry. It can improve local circulation of blood and lymph, allowing for better detoxification and redistribution of needed bodily resources.
Here’s an example dry brushing body brush on Amazon; this writer has one and hates it, but I’ve also tried with other kinds of brush and hate them too, so it seems to be a me thing rather than a brush thing, and I have desisted in trying, now. Maybe you will like it better; many people do.
Self-massage: or massage by someone else, if that’s an option for you and you prefer. In this case, it works by a different mechanism than dry brushing; this time it’s working by the same principle as the medical techniques described in the previous section; it’s physically breaking down the toughened bits of connective tissue.
Here’s an example wooden massage roller on Amazon; this writer has one and loves it; it’s sooooooo good. I got it as a matter of general maintenance for my fascia, but it’s also very good if I get a muscular pain now and again. As for cellulite, I personally get just a little cellulite sometimes (in the backs of my thighs), and whenever I use this regularly, it goes away for at least a while.
A quick note in closing
Cellulite is normal for women and is not unhealthy. Much like gray hair for example, it’s something that can be increased by poor health, but the thing itself isn’t intrinsically unhealthy, and most of us get it to some degree at some point.
Nevertheless, aesthetic factors can also have a role to play in mental health, and we tend to feel best when we like the way our body looks. If for you that means wanting less/no cellulite, then the above are some ways towards that.
As a bonus, most of the nonmedical options are directly good for the physical health anyway, so doing them is of course good.
In particular that last one (the wooden massage roller), because that connective tissue we talked about? It matters for a lot more than just cellulite, and is heavily implicated in a lot of kinds of chronic pain, so it pays to keep it in good health:
Fascia: Why (And How) You Should Take Care Of Yours
(that article, also written by this same writer by the way, suggests a vibrating foam roller—those are very popular; I just really love my wooden one, and find it more effective)
Take care!

CBD Oil’s Many Benefits
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.
CBD Oil: What Does The Science Say?
First, a quick legal (and practical) note:
CBD and THC are both derived from the hemp or cannabis plant, but only the latter has euphoriant psychoactive effects, i.e., will get you high. We’re writing here about CBD derived from hemp and not containing THC (thus, will not get you high).
Laws and regulations differ far too much from place to place for us to try to advise here, so please check your own local laws and regulations. And also, while you’re at it, with your doctor and/or pharmacist.
As ever, this newsletter is for purposes of education and enjoyment, and does not constitute any kind of legal (or medical) advice.
With that in mind, onwards to today’s research review…
CBD for Pain Relief
CBD has been popularly touted as a pain relief panacea, and there are a lot of pop-science articles out there “debunking” this, but…
The science seems to back it up. We couldn’t find studies refuting the claim (of CBD as a viable pain relief option). We did, however, find research showing it was good against:
Note that that latter (itself a research review, not a single study, hence covering a lot of bases) describes it matter-of-factly, with no caveats or weasel-words, as:
“CBD, a non-euphoriant, anti-inflammatory analgesic with CB1 receptor antagonist and endocannabinoid modulating effects”
As a quick note: all of the above is about the topical use of CBD oil, not any kind of ingestion
CBD for Anxiety/Depression
There’s a well-cited study with what honestly we think was a bit of a small sample size, but compelling results within that:
A study published in the Brazilian Journal of Psychiatry tested the anxiety levels of 57 men in a simulated public speaking test.
Compared to placebo…
- Those who received 300mg of CBD experienced significantly reduced anxiety during the test.
- Those who received either 150mg or 600mg of CBD experienced more anxiety during the test than the 300mg group
- This means there’s a sweet spot to the dosage
There was also a clinical study that found CBD to have anti-depressant effects.
The methodology was a lot more robust, but the subjects were mice. We can’t have everything in one study, apparently! There is probably a paucity of human volunteers to have their brain slices looked at after tests, though.
Anyway, what makes this study interesting is that it measured quite an assortment of biological markers in the brain, and found that the CBD had a similar physiological effect to the antidepressant imipramine.
CBD for Treating Opioid Addiction
There are a lot of studies for this, both animal and human, but we’d like to put the spotlight on a human study (with the participation of heroin users) that found:
❝Within one week, CBD significantly reduced cravings, anxiety, resting heart rate, and salivary cortisol levels. No serious adverse effects were found.❞
This is groundbreaking because the very thing about heroin is that it’s so addictive and the body rapidly needs more and more of it. You might think “duh”, but most people don’t realize this part:
Heroin is attractive because it offers (and delivers) an immediate guaranteed “downer”, instant relaxation… with none of the bad side effects of, for example, alcohol. No nausea, no hangover, nothing.
The problem is that the body gets tolerant to heroin very quickly, meaning your doses need to get bigger and more frequent to have the same effect.
Before you know it, what seemed like an affordable “self-medication for a stressful life” is very much out of control! Many doctors have personally found this out the hard way.
So, it’s ruinous:
- first to your financial health, as the costs rapidly spiral
- then to your physical health, as you either suffer from withdrawal or eventually overdose
Consequently, heroin is an incredibly easy drug to get hooked onto, and incredibly difficult to get back off.
So CBD offering relief is really a game-changer.
And more…
CBD has been well-studied and found to be effective for a lot of things, more than we could hope to cover in a single edition here.
Some further reading that may interest you includes:
- CBD against Diabetes in mice / in vitro / in humans
- CBD against neurological diseases (in general, in humans)
- CBD against arthritis in mice / in humans
- CBD specifically against the pain of rheumatoid arthritis / of osteoarthritis
Let us know if there’s any of these (or other) conditions you’d like us to look more into the CBD-related research for, because there’s a lot! You can always hit reply to any of our emails, or use the feedback widget at the bottom

Ageless Athletes – by Dr. Jim Madden
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.
This is an approach to strength and fitness training specifically for the 50+ crowd, and/but even more specifically for the 50+ crowd who do not wish to settle for mediocrity. In short, it’s for those who not only wish to stay healthy and have good mobility, but also who wish to be and remain athletic.
It does not assume extant athleticism, but nor does it assume complete inexperience. It provides a fairly ground-upwards entry to a training program that then quickly proceeds to competitive levels of athleticism.
The author himself details his own journey from being in his 30s, overweight and unfit, to being in his 50s and very athletic, with before and after photos. Granted, those are 20 years in between, but all the same, it’s a good sign when someone gets stronger and fitter with age, rather than declining.
The style of the book is quite casual, and/but after the introductory background and pep talk, is quite pragmatic and drops the additional fluff. In particular, older readers may enjoy the “Old Workhorse” protocol, as a tailored measured progression system.
In terms of expected equipment by the way, some is bodyweight and some is with weights; kettlebells in particular feature strongly, since this is about functional strength and not bodybuilding.
In the category of criticism, he does refer to his other books and generally assumes the reader is reading all his work, so it may not be for everyone as a standalone book.
Bottom line: if you’re 50+ and are wondering how to gain/maintain a high level athleticism, this book can definitely help with that.

The Beautiful Cure – by Dr. Daniel Davis
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.
This one is not just a book about the history of immunology and a primer on how the immune system works. It is those things too, but it’s more:
Dr. Daniel Davis, a professor of immunology and celebrated researcher in his own right, bids us look at not just what we can do, but also what else we might.
This is not to say that the book is speculative; Dr. Davis deals in data rather than imaginings. He also cautions us against falling prey to sensationalization of the “beautiful cures” that the field of immunology is working towards. What, then, are these “beautiful cures”?
Just like our immune systems (in the plural; by Dr. Davis’ count, primarily talking about our innate and adaptive immune systems) can in principle deal with any biological threat, but in practice don’t always get it right, the same goes for our medicine.
He argues that in principle, we categorically can cure any immune-related disease (including autoimmune diseases, and tangentially, cancer). The theoretical existence of such cures is a mathematically known truth. The practical, contingent existence of them? That’s what takes the actual work.
The style of the book is accessible pop science, with a hard science backbone from start to finish.
Bottom line: if you’d like to know more about immunology, and be inspired with hope and wonder without getting carried away, this is the book for you.
