HBD: The Human Being Diet – by Petronella Ravenshear

We don’t often review diet books, so why did this one catch our attention? The answer lies in its comprehensive nature without being excessively long and complex.
Ravenshear (a nutritionist) brings a focus on metabolic balance, and what will and won’t work for keeping it healthy.
The first part of the book is mostly informational; covering such things as blood sugar balance, gut health, hormones, and circadian rhythm considerations, amongst others.
The second, larger part of the book is mostly instructional; do this and that, don’t do the other, guidelines on quantities and timings, and what things may be different for some people, and what to do about those.
The style is conversational and light, but well-grounded in good science.
Bottom line: if you’d like a “one-stop shop” for giving your diet an overhaul, this book is a fine choice.

When supplies resume, should governments subsidise drugs like Ozempic for weight loss? We asked 5 experts
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.
Hundreds of thousands of people worldwide are taking drugs like Ozempic to lose weight. But what do we actually know about them? This month, The Conversation’s experts explore their rise, impact and potential consequences.
You’ve no doubt heard of Ozempic but have you heard of Wegovy? They’re both brand names of the drug semaglutide, which is currently in short supply worldwide.
Ozempic is a lower dose of semaglutide, and is approved and used to treat diabetes in Australia. Wegovovy is approved to treat obesity but is not yet available in Australia. Shortages of both drugs are expected to last throughout 2024.
Both drugs are expensive. But Ozempic is listed on Australia’s Pharmaceutical Benefits Schedule (PBS), so people with diabetes can get a three-week supply for A$31.60 ($7.70 for concession card holders) rather than the full price ($133.80).
Wegovy isn’t listed on the PBS to treat obesity, meaning when it becomes available, users will need to pay the full price. But should the government subsidise it?
Wegovy’s manufacturer will need to make the case for it to be added to the PBS to an independent advisory committee. The company will need to show Wegovy is a safe, clinically effective and cost-effective treatment for obesity compared to existing alternatives.
In the meantime, we asked five experts: when supplies resume, should governments subsidise drugs like Ozempic for weight loss?
Four out of five said yes
This is the last article in The Conversation’s Ozempic series. Read the other articles here.

Do We Need Sunscreen In Winter, Really?
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.
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 😎
❝I keep seeing advice that we shoudl wear sunscreen out in winter even if it’s not hot or sunny, but is there actually any real benefit to this?❞
Short answer: yes (but it’s indeed not as critical as it is during summer’s hot/sunny days)
Longer answer: first, let’s examine the physics of summer vs winter when it comes to the sun…
In summer (assuming we live far enough from the equator to have this kind of seasonal variation), the part of the planet where we live is tilted more towards the sun. This makes it closer, and more importantly, it’s more directly overhead during the day. The difference in distance through space isn’t as big a deal as the difference in distance through the atmosphere. When the sun is more directly overhead, its rays have a shorter path through our atmosphere, and thus less chance of being blocked by cloud cover / refracted elsewhere / bounced back off into space before it even gets that far.
In winter, the opposite of all that is true.
Morning/evening also somewhat replicate this compared to midday, because the sun being lower in the sky has a similar effect to seasonal variation causing it to be less directly overhead.
For this reason, even though visually the sun may be just as bright on a winter morning as it is on a summer midday, the rays have been filtered very differently by the time they get to us.
This is one reason why you’re much less likely to get sunburned in the winter, compared to the summer (others include the actual temperature difference, your likely better hydration, and your likely more modest attire protecting you).
However…
The reason it is advisable to wear sunscreen in winter is not generally about sunburn, and is rather more about long-term cumulative skin damage (ranging from accelerated aging to cancer) caused by the UV rays—specifically, mostly UVA rays, since UVB rays (with their higher energy but shorter wavelength) have nearly all been blocked by the atmosphere.
Here’s a good explainer of that from the American Cancer Society:
UV (Ultraviolet) Radiation and Cancer Risk
👆 this may seem like a no-brainer, but there’s a lot explained here that demystifies a lot of things, covering ionizing vs non-ionizing radiation, x-rays and gamma-rays, the very different kinds of cancer caused by different things, and what things are dangerous vs which there’s no need to worry about (so far as best current science can say, at least).
Consequently: yes, if you value your skin health and avoidance of cancer, wearing sunscreen when out even in the winter is a good idea. Especially if your phone’s weather app says the UV index is “moderate” or above, but even if it’s “low”, it doesn’t hurt to include it as part of your skincare routine.
But what if sunscreens are dangerous?
Firstly, not all sunscreens are created equal:
Learn more: Who Screens The Sunscreens?
Secondly: consider putting on a protective layer of moisturizer first, and then the sunscreen on top. Bear in mind, this is winter we’re talking about, so you’re probably not going out in a bikini, so this is likely a face-neck-hands job and you’re done.
What about vitamin D?
Humans evolved to have more or less melanin in our skin depending on where we lived, and white people evolved to wring the most vitamin D possible out of the meagre sun far from the equator. Black people’s greater melanin, on the other hand, offers some initial protection against the sun (but any resultant skin cancer is then more dangerous than it would be for white people if it does occur, so please do use sunscreen whatever your skintone).
Nowadays many people live in many places which may or may not be the places we evolved for, and so we have to take that into account when it comes to sun exposure.
Here’s a deeper dive into that, for those who want to learn:

Exercise and Fat Loss (5 Things You Need To Know)
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.
It’s easy to think “I’ll eat whatever; I can always burn it off later”, and if it’s an odd occasion, then that’s fine; indeed, a fit and healthy body can usually weather small infrequent dietary indiscretions easily. But…
You can’t outrun a bad diet
Exercise can create a calorie deficit, but over time, the body balances this out by adjusting one’s metabolism, leading to a plateau in fat loss—and as you might know, you can’t out-exercise a bad diet. On the contrary, dietary adjustments are crucial for fat loss and body recomposition.
About that calorie deficit in the first place, by the way: extreme calorie deficits through exercise alone can lead to muscle loss, reduced energy, and thus sabotage long-term fat loss because having muscle mass increases one’s base metabolic rate (while having fat does not).
Another thing to bear in mind about exercise is that longer workouts without adequate rests in between can cause burnout, injury, or weight gain due to the body doing its best to conserve energy.
So, a good diet is a necessary condition for both muscle maintenance and fat loss.
Five Key Diet Tips:
- Include foods you love: don’t feel obliged cut out favorite foods that are a little unhealthy; incorporate them in moderation for sustainability.
- Keep adjustments small: avoid making drastic dietary changes all at once; make gradual tweaks to prevent feeling deprived.
- Prioritize protein: focus on including a protein source in every meal to increase satiety and aid in muscle building.
- Avoid low-calorie diets: drastically cutting calories can lead to muscle loss, metabolic adaptation, and overeating.
- Embrace diet evolution: changes may not feel sustainable at first, but adjustments over time help achieve long-term balance. You can always “adjust course” as you go.

Walk Like You’re 20 Years Younger Again

How fit, healthy, strong, and mobile were you 20 years ago? For most people, the answer is “better than now”. Physiotherapist Dr. Doug Weiss has advice on turning back the clock:
The exercises
If you already have no problems walking, this one is probably not for you. However, if you’re not so able to comfortably walk as you used to be, then Dr. Weiss recommends:
- Pillow squat: putting pillow on a chair, crossing hands on chest, standing up and sitting down. Similar to the very important “getting up off the floor without using your hands” exercise, but easier.
- Wall leaning: standing against a wall with heels 4″ away from it, crossing arms over chest again, and pulling the body off the wall using the muscles in the front of the shin. Note, this means not cheating by using other muscles, leveraging the upper body, pushing off with the buttocks, or anything else like that.
- Stepping forward: well, this certainly is making good on the promise of walking like we did 20 years ago; there sure was a lot of stepping forward involved. More seriously, this is actually about stepping over some object, first with support, and then without.
- Heel raise: is what it sounds like, raising up on toes and back down again; first with support, then without.
- Side stepping: step sideways 2–3 steps in each direction. First with support, then without. Bonus: if your support is your partner, then congratulations, you are now dancing bachata.

Eat Well With Arthritis – by Emily Johnson, with Dr. Deepak Ravindran
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.
Author Emily Johnson was diagnosed with arthritis in her early 20s, but it had been affecting her life since the age of 4. Suffice it to say, managing the condition has been integral to her life.
She’s written this book with not only her own accumulated knowledge, but also the input of professional experts; the book contains insights from chronic pain specialist Dr. Deepak Ravindran, and gets an additional medical thumbs-up in a foreword by rheumatologist Dr. Lauren Freid.
The recipes themselves are clear and easy, and the ingredients are not obscure. There’s information on what makes each dish anti-inflammatory, per ingredient, so if you have cause to make any substitutions, that’s useful to know.
Speaking of ingredients, the recipes are mostly plant-based (though there are some chicken/fish ones) and free from common allergens—but not all of them are, so each of those is marked appropriately.
Beyond the recipes, there are also sections on managing arthritis more generally, and information on things to get for your kitchen that can make your life with arthritis a lot easier!
Bottom line: if you have arthritis, cook for somebody with arthritis, or would just like a low-inflammation diet, then this is an excellent book for you.

How to Think More Effectively – by Alain de Botton
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 brain is our most powerful organ, and our mind is an astonishing thing. So why do we sometimes go off-piste?
The School of Life‘s Alain de Botton lays out for us a framework of cumulative thinking, directions for effort, and unlikely tools for cognitive improvement.
The book especially highlights the importance of such things as…
- making time for cumulative thinking
- not, however, trying to force it
- working with, rather than in spite of, distractions
- noting and making use of our irrationalities
- taking what we think/do both seriously and lightly, at once
- practising constructive self-doubt
The style is as clear and easy as you may have come to expect from Alain de Botton / The School of Life, and yet, its ideas are still likely to challenge every reader in some (good!) way.
Bottom line: if you would like what you think, say, do to be more meaningful, this book will help you to make the most of your abilities!
