How To Do HIIT (Without Wrecking Your Body)
High-Intensity Interval Training, henceforth “HIIT”, is a well-researched and well-evidenced approach to exercise that gives powerful health benefits.
Specifically, health benefits that we don’t get from moderate exercise (as important as that is too) or endurance training.
Super-quick overview of the benefits first:
- Burns more calories than other forms of exercise
- Boosts your metabolic rate for hours afterwards
- …which means it actually works* for fat loss
- Reduces blood pressure (unless already healthy)
- Can promote muscle growth (depends on other factors)
*remember that most forms of exercise aren’t very good for fat loss, because our metabolism will slow afterwards to compensate. So HIIT flipping this one is quite a big deal.
What actually is it?
HIIT means exercise sessions in which one alternates between high intensity “maximum effort” bursts, and short recovery periods during which more moderate exercise is performed.
An example for runners could be switching between sprinting or jogging, changing mode each time one passes a street light.
❝A total of only two minutes of sprint interval exercise was sufficient to elicit similar responses as 30 minutes of continuous moderate intensity aerobic exercise❞
What did you mean about not wrecking your body? Is that… Likely?
Hopefully not, but it’s a barrier to some! We are not all twenty-something college athletes, after all, and our bodies aren’t always as durable as they used to be.
HIIT relies on intense exercise and short recovery periods, but what if our bodies are not accustomed to intense exercise, and need longer recovery periods? Can we still get the same benefits?
The trick is not to change the intensity or the recovery periods, but the exercise itself.
For HIIT to work the “intense” part has to be best-effort or approaching such. That part’s not negotiable. The recovery periods can be stretched a bit if you need to, but with the right tweaks, you ideally won’t have to do that.
Great! How?
First, note that you can do resistance interval training without impact. For example, if you crank up the resistance on an exercise bike or similar machine, you will be doing resistance training along with your cardio, and you’ll be doing it without the impact on your joints that you would if out pounding the pavement on foot.
(Running is fine if your body is used to it, but please don’t make HIIT your first running exercise in a decade)
Second, consider your environment. That exercise bike? You can get off it any time and you’re already at home (or perhaps your gym, with your car outside). Not so if you took up mountain biking or road racing.
Third, go for what is gentle in motion, even if it’s not resistance work per se. Swimming is a fabulous option for most people, and can absolutely be done with HIIT principles. Since vision is often obscured while swimming, counting strokes can be a good way to do HIIT. For example, ten strokes max effort, ten strokes normal, repeat. Do make sure you are aware of where the end of the pool is, though!
Fourth, make it fun! Ok, this one’s not about the safety quite so much, but it is about sustainability, and that’s critical for practical purposes too. You will only continue an exercise routine that you enjoy, after all.
- Could you curate a musical playlist that shifts tempo to cue your exercise mode intervals?
- Could you train with an exercise partner? Extra fun if this has a “relay race” feel to it, i.e. when one person completes a high intensity interval, the other person must now begin theirs.
Need some pointers getting started?
There are a lot of HIIT apps out there, so you can just search for that on your device of choice.
But!
We at 10almonds have recommended 7-Minute Workout before, which is available for iOS and for Android, and we stand by that as a great starting choice.
Enjoy!

“Osteoporosis” and “break” often don’t go well together, but here they do. So, what’s the breakthrough here?
There isn’t one, honestly. But if we overlook the marketing choices and focus on the book itself, the content here is genuinely good:
The book offers a comprehensive multivector approach to combatting osteoporosis, e.g:
- Diet
- Exercise
- Other lifestyle considerations
- Supplements
- Hormones
- Drugs
The author considers drugs a good and important tool for some people with osteoporosis, but not most. The majority of people, he considers, will do better without drugs—by tackling things more holistically.
The advice here is sound and covers all reasonable angles without getting hung up on the idea of there being a single magical solution for all.
Bottom line: if you’re looking for a book that’s a one-stop-shop for strategies against osteoporosis, this is a good option.

No, beetroot isn’t vegetable Viagra. But here’s what else it can do
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.
Beetroot has been in the news for all the wrong reasons. Supply issues in recent months have seen a shortage of tinned beetroot on Australian supermarket shelves. At one point, a tin was reportedly selling on eBay for more than A$65.
But as supplies increase, we turn our attention to beetroot’s apparent health benefits.
Is beetroot really vegetable Viagra, as UK TV doctor Michael Mosley suggests? What about beetroot’s other apparent health benefits – from reducing your blood pressure to improving your daily workout? Here’s what the science says.
What’s so special about beetroot?
Beetroot – alongside foods such as berries, nuts and leafy greens – is a “superfood”. It contains above-average levels per gram of certain vitamins and minerals.
Beetroot is particularly rich in vitamin B and C, minerals, fibre and antioxidants.
Most cooking methods don’t significantly alter its antioxidant levels. Pressure cooking does, however, lower levels of carotenoid (a type of antioxidant) compared to raw beetroot.
Processing into capsules, powders, chips or juice may affect beetroot’s ability to act as an antioxidant. However, this can vary between products, including between different brands of beetroot juice.
Is beetroot really vegetable Viagra?
The Romans are said to have used beetroot and its juice as an aphrodisiac.
But there’s limited scientific evidence to say beetroot improves your sex life. This does not mean it doesn’t. Rather, the vast number of scientific studies looking at the effect of beetroot have not measured libido or other aspects of sexual health.
How could it work?
When we eat beetroot, chemical reactions involving bacteria and enzymes transform the nitrate in beetroot into nitrite, then to nitric oxide. Nitric oxide helps dilate (widen) blood vessels, potentially improving circulation.
The richest sources of dietary nitric oxide that have been tested in clinical studies are beetroot, rocket and spinach.
Nitric oxide is also thought to support testosterone in its role in controlling blood flow before and during sex in men.
Beetroot’s ability to improve blood flow can benefit the circulatory system of the heart and blood vessels. This may positively impact sexual function, theoretically in men and women.
Therefore, it is reasonable to suggest there could be a modest link between beetroot and preparedness for sex, but don’t expect it to transform your sex life.
What else could it do?
Beetroot has received increasing attention over recent years due to its antioxidant and anti-tumour effect in humans.
Clinical trials have not verified all beetroot’s active ingredients and their effects. However, beetroot may be a potentially helpful treatment for various health issues related to oxidative stress and inflammation, such as cancer and diabetes. The idea is that you can take beetroot supplements or eat extra beetroot alongside your regular medicines (rather than replace them).
There is evidence beetroot juice can help lower systolic blood pressure (the first number in your blood pressure reading) by 2.73-4.81 mmHg (millimetres of mercury, the standard unit of measuring blood pressure) in people with high blood pressure. Some researchers say this reduction is comparable to the effects seen with certain medications and dietary interventions.
Other research finds even people without high blood pressure (but at risk of it) could benefit.
Beetroot may also improve athletic performance. Some studies show small benefits for endurance athletes (who run, swim or cycle long distances). These studies looked at various forms of the food, such as beetroot juice as well as beetroot-based supplements.
How to get more beetroot in your diet
There is scientific evidence to support positive impacts of consuming beetroot in whole, juice and supplement forms. So even if you can’t get hold of tinned beetroot, there are plenty of other ways you can get more beetroot into your diet. You can try:
- raw beetroot – grate raw beetroot and add it to salads or coleslaw, or slice beetroot to use as a crunchy topping for sandwiches or wraps
- cooked beetroot – roast beetroot with olive oil, salt and pepper for a flavour packed side dish. Alternatively, steam beetroot and serve it as a standalone dish or mixed into other dishes
- beetroot juice – make fresh beetroot juice using a juicer. You can combine it with other fruits and vegetables for added flavour. You can also blend raw or cooked beetroot with water and strain to make a juice
- smoothies – add beetroot to your favourite smoothie. It pairs well with fruits such as berries, apples and oranges
- soups – use beetroot in soups for both flavour and colour. Borscht is a classic beetroot soup, but you can also experiment with other recipes
- pickled beetroot – make pickled beetroot at home, or buy it from the supermarket. This can be a tasty addition to salads or sandwiches
- beetroot hummus – blend cooked beetroot into your homemade hummus for a vibrant and nutritious dip. You can also buy beetroot hummus from the supermarket
- grilled beetroot – slice beetroot and grill it for a smoky flavour
- beetroot chips – slice raw beetroot thinly, toss the slices with olive oil and your favourite seasonings, then bake or dehydrate them to make crispy beetroot chips
- cakes and baked goods – add grated beetroot to muffins, cakes, or brownies for a moist and colourful twist.
You can add beetroot to baked goods. Ekaterina Khoroshilova/Shutterstock Are there any downsides?
Compared to the large number of studies on the beneficial effects of beetroot, there is very little evidence of negative side effects.
If you eat large amounts of beetroot, your urine may turn red or purple (called beeturia). But this is generally harmless.
There have been reports in some countries of beetroot-based dietary supplements contaminated with harmful substances, yet we have not seen this reported in Australia.
What’s the take-home message?
Beetroot may give some modest boost to sex for men and women, likely by helping your circulation. But it’s unlikely to transform your sex life or act as vegetable Viagra. We know there are many contributing factors to sexual wellbeing. Diet is only one.

Visceral Belly Fat & How To Lose It

Visceral Belly Fat & How To Lose It
We’ve talked before about how waist circumference is a much more useful indicator of metabolic health than BMI.
So, let’s say you’ve a bit more around the middle than you’d like, but it stubbornly stays there. What’s going on underneath what you can see, why is it going on, and how can you get it to change?
What is visceral fat?
First, let’s talk about subcutaneous fat. That’s the fat directly under your skin. Women usually have more than men, and that’s perfectly healthy (up to a point); it’s supposed to be that way. We (women) will tend to accumulate this mostly in places such as our breasts, hips, and butt, and work outwards from there. Men will tend to put it on more to the belly and face.
Side-note: if you’re undergoing (untreated) menopause, the changes in your hormone levels will tend to result in more subcutaneous fat to the belly and face too. That’s normal, and/but normal is not always good, and treatment options are great (with hormone replacement therapy, HRT, topping the list).
Visceral fat (also called visceral adipose tissue), on the other hand, is the fat of the viscera—the internal organs of the abdomen.
So, this is fat that goes under your abdominal muscles—you can’t squeeze this (directly).
So what can we do?
Famously “you can’t do spot reduction” (lose fat from a particular part of your body by focusing exercises on that area), but that’s about subcutaneous fat. There are things you can do that will reduce your visceral fat in particular.
Some of these advices you may think “that’s just good advice for losing fat in general” and it is, yes. But these are things that have the biggest impact on visceral fat.
Cut alcohol use
This is the biggie. By numerous mechanisms, some of which we’ve talked about before, alcohol causes weight gain in general yes, but especially for visceral fat.
Get better sleep
You might think that hitting the gym is most important, but this one ranks higher. Yes, you can trim visceral fat without leaving your bed (and even without getting athletic in bed, for that matter). Not convinced?
- Here’s a study of 101 people looking at sleep quality and abdominal adiposity
- Oh, and here’s a meta-analysis with 56,000 people (finding the same thing), in case that one study didn’t convince you.
So, the verdict is clear: you snooze, you lose (visceral fat)!
Tweak your diet
You don’t have to do a complete overhaul (unless you want to), but a few changes can make a big difference, especially:
- Getting more fiber (this is the biggie when it comes to diet)
- Eating less sugar (not really a surprise, but relevant to mention)
- Eat whole foods (skip the highly processed stuff)

Why Do We Have Pores, And Could We Not?

It’s Q&A Day at 10almonds!
Have a question or a request? We love to hear from you!
In cases where we’ve already covered something, we might link to what we wrote before, but will always be happy to revisit any of our topics again in the future too—there’s always more to say!
As ever: if the question/request can be answered briefly, we’ll do it here in our Q&A Thursday edition. If not, we’ll make a main feature of it shortly afterwards!
So, no question/request too big or small
❝Do we really need pores, and why are they bigger on the face?❞
Pores secrete sweat or sebum (there are different kinds of pores for each).
If we didn’t have sweat pores, we’d be unable to sweat, which superficially may seem like a bonus, but it’d make us prone to overheating (like dogs, pigs, and other mammals that cannot sweat).
If we didn’t have sebum pores (usually called hair follicles, which are supplied by a sebaceous gland), we’d be completely hairless, and also unable to supply our skin with natural oils that keep it healthy. So we’d have no hair and very unhappy skin.
Which is ironic, because to believe beauty magazines, we must at all costs minimize our pores (and indeed, interventions like botox* can kill them).
*Let’s give that its full name though:
Suffice it to say, we do not recommend getting injected with neurotoxins unless it is truly necessary to ward off a greater harm.
As for being bigger on the face, they need not be, but sebaceous glands are more active and numerous there, being most active and numerous in the face/forehead—which is why oily skin is more likely to appear there than other parts of the body.
If your facial sebaceous glands are too active for your liking…
…there are ways to reduce that, a simple and relatively gentle way (relative, for example, botox) is with retinoids, including retinols or retinoic acids. Here’s some of the science of that; the paper is about treating acne, but the mechanism of action is the same (down-regulating the sebaceous glands’ action):
The potential side-effects, however were noted as:
- Cheilitis
- Desquamation of the skin
- Pruritus
Which, in translation from sciencese, means:
- Chapped lips
- Flaky skin
- Itchiness
Which aren’t necessarily fun, which is why with retinoids are best taken in very small doses at first to see how your skin reacts.
Remember when we said what your skin would be like without pores? This is what would happen, only much worse.
Take care!

To Medicate or Not? That is the Question! – by Dr. Asha Bohannon
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.
Medications are, of course, a necessity of life (literally!) for many, especially as we get older. Nevertheless, overmedication is also a big problem that can cause a lot of harm too, and guess what, it comes with the exact same “especially as we get older” tag too.
So, what does Dr. Bohannon (a doctor of pharmacy, diabetes educator, and personal trainer too) recommend?
Simply put: she recommends starting with a comprehensive health history assessment and analysing one’s medication/supplement profile, before getting lab work done, tweaking all the things that can be tweaked along the way, and—of course—not neglecting lifestyle medicine either.
The book is prefaced and ended with pep talks that probably a person who has already bought the book does not need, but they don’t detract from the practical content either. Nevertheless, it feels a little odd that it takes until chapter 4 to reach “step 1” of her 7-step method!
The style throughout is conversational and energetic, but not overly padded with hype; it’s just a very casual style. Nevertheless, she brings to bear her professional knowledge and understanding as a doctor of pharmacy, to include her insights into the industry that one might not observe from outside of it.
Bottom line: if you’d like to do your own personal meds review and want to “know enough to ask the right questions” before bringing it up with your doctor, this book is a fine choice for that.

Paulina Porizkova (Former Supermodel) Talks Menopause, Aging, & Appearances
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.
Are supermodels destined to all eventually become “Grizabella the Glamor Cat”, a washed-up shell of their former glory? Is it true that “men grow cold as girls grow old, and we all lose our charms in the end”? And what—if anything—can we do about it?
Insights from a retired professional
Paulina Porizkova is 56, and she looks like she’s… 56, maybe? Perhaps a little younger or a bit older depending on the camera and lighting and such.
It’s usually the case, on glossy magazine covers and YouTube thumbnails, that there’s a 20-year difference between appearance and reality, but not here. Why’s that?
Porizkova noted that many celebrities of a similar age look younger, and felt bad. But then she noted that they’d all had various cosmetic work done, and looked for images of “real” women in their mid-50s, and didn’t find them.
Note: we at 10almonds do disagree with one thing here: we say that someone who has had cosmetic work done is no less real for it; it’s a simple matter of personal choice and bodily autonomy. She is, in our opinion, making the same mistake as people make when they say such things as “real people, rather than models”, as though models are not also real people.
Porizkova found modelling highly lucrative but dehumanizing, and did not enjoy the objectification involved—and she enjoyed even less, when she reached a certain age, negative comments about aging, and people being visibly wrong-footed when meeting her, as they had misconceptions based on past images.
As a child and younger adult through her modelling career, she felt very much “seen and not heard”, and these days, she realizes she’s more interesting now but feels less seen. Menopause coincided with her marriage ending, and she felt unattractive and ignored by her husband; she questioned her self-worth, and felt very bad about it. Then her husband (they had separated, but had not divorced) died, and she felt even more isolated—but it heightened her sensitivity to life.
In her pain and longing for recognition, she reached out through her Instagram, crying, and received positive feedback—but still she struggles with expressing needs and feeling worthy.
And yet, when it comes to looks, she embraces her wrinkles as a form of expression, and values her natural appearance over cosmetic alterations.
She describes herself as a work in progress—still broken, still needing cleansing and healing, but proud of how far she’s come so far, and optimistic with regard to the future.
