The weight-loss drug Wegovy is now available in Australia.

Wegovy is administered as a once-weekly injection and is approved specifically for weight management. It’s intended to be used in combination with a reduced-energy diet and increased physical activity.

So how does Wegovy work and how much weight can you expect to lose while taking it? And what are the potential risks – and costs – for those who use it?

Let’s look at what the science says.

What is Wegovy?

Wegovy is a brand name for the medication semaglutide. Semaglutide is a glucagon-like peptide-1 receptor agonist (GLP-1RA). This means it makes your body’s own glucagon-like peptide-1 hormone, called GLP-1 for short, work better.

Normally when you eat, the body releases the GLP-1 hormone which helps signal to your brain that you are full. Semaglutides enhance this effect, leading to a feeling of fullness, even when you haven’t eaten.

Another role of GLP-1 is to stimulate the body to produce more insulin, a hormone which helps lower the level of glucose (sugar) in the blood. That’s why semaglutides have been used for several years to treat type 2 diabetes.

How does Wegovy differ from Ozempic?

Like Wegovy, Ozempic is a semaglutide. The way Wegovy and Ozempic work in the body are essentially the same. They’re made by the same pharmaceutical company, Novo Nordisk.

But there are two differences:

1) They are approved for two different (but related) reasons.

In Australia (and the United States), Ozempic is approved for use to improve blood glucose levels in adults with type 2 diabetes. By managing blood glucose levels effectively, the medication aims to reduce the risk of major complications, such as heart disease.

Wegovy is approved for use alongside diet and exercise for people with a body mass index (BMI) of 30 or greater, or 27 or greater but with other conditions such as high blood pressure.

Wegovy can also be used in people aged 12 years and older. Like Ozempic, Wegovy aims to reduce the risk of future health complications, including heart disease.

2) They are both injected but come in different strengths.

Ozempic is available in pre-loaded single-dose pens with varying dosages of 0.25 mg, 0.5 mg, 1 mg, or 2 mg per injection. The dose can be slowly increased, up to a maximum of 2 mg per week, if needed.

Wegovy is available in prefilled single-dose pens with doses of 0.25 mg, 0.5 mg, 1 mg, 1.7 mg, or 2.4 mg. The treatment starts with a dose of 0.25 mg once weekly for four weeks, after which the dose is gradually increased until reaching a maintenance dose of 2.4 mg weekly.

While it’s unknown what the impact of Wegovy’s introduction will be on Ozempic’s availability, Ozempic is still anticipated to be in low supply for the remainder of 2024.

Is Wegovy effective for weight loss?

Given Wegovy is a semaglutide, there is very strong evidence it can help people lose weight and maintain this weight loss.

A recent study found that over four years, participants taking Wevovy as indicated experienced an average weight loss of 10.2% body weight and a reduction in waist circumference of 7.7cm.

For those who stop taking the medication, analyses have shown that about two-thirds of weight lost is regained.

What are the side effects of Wegovy?

The most common side effects are nausea and vomiting.

However, other serious side effects are also possible because of the whole-of-body impact of the medication. Thyroid tumours and cancer have been detected as a risk in animal studies, yet are rarely seen in human scientific literature.

In the four-year Wegovy trial, 16.6% of participants who received Wegovy (1,461 people) experienced an adverse event that led to them permanently discontinuing their use of the medication. This was higher than the 8.2% of participants (718 people) who received the placebo (with no active ingredient).

Side effects included gastrointestinal disorders (including nausea and vomiting), which affected 10% of people who used Wegovy compared to 2% of people who used the placebo.

Gallbladder-related disorders occurred in 2.8% of people who used Wegovy, and 2.3% of people who received the placebo.

Recently, concerns about suicidal thoughts and behaviours have been raised, after a global analysis reviewed more than 36 million reports of adverse events from semaglutide (Ozempic or Wegovy) since 2000.

There were 107 reports of suicidal thoughts and self-harm among people taking semaglutide, sadly including six actual deaths. When people stopped the medication, 62.5% found the thoughts went away. What we don’t know is whether dose, weight loss, or previous mental health status or use of antidepressants had a role to play.

Finally, concerns are growing about the negative effect of semaglutides on our social and emotional connection with food. Anecdotal and scientific evidence suggests people who use semaglutides significantly reduce their daily dietary intake (as anticipated) by skipping meals and avoiding social occasions – not very enjoyable for people and their loved ones.

How can people access Wegovy?

Wegovy is available for purchase at pharmacists with a prescription from a doctor.

But there is a hefty price tag. Wegovy is not currently subsidised through the Pharmaceutical Benefits Scheme, leaving patients to cover the cost. The current cost is estimated at around A$460 per month dose.

If you’re considering Wegovy, make an appointment with your doctor for individual advice.

    Querying Quercetin

    Quercetin is a flavonoid (and thus, antioxidant) pigment found in many plants. Capers, radishes, and coriander/cilantro score highly, but the list is large:

    USDA Database for the Flavonoid Content of Selected Foods

    Indeed,

    ❝Their regular consumption is associated with reduced risk of a number of chronic diseases, including cancer, cardiovascular disease (CVD) and neurodegenerative disorders❞

    ~ Dr. Aleksandra Kozłpwsla & Dr. Dorota Szostak-Wegierek

    For this reason, quercetin is often sold/consumed as a supplement on the strength of its health-giving properties.

    But what does the science say?

    Quercetin and inflammation

    In short, it helps:

    ❝500 mg per day quercetin supplementation for 8 weeks resulted in significant improvements in clinical symptoms, disease activity, hs-TNFα, and Health Assessment Questionnaire scores in women with rheumatoid athritis

  • Why You Should Diversify Your Nuts!

    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.

    Time to go nuts for nuts!

    Nuts, in popular perception, range from “basically the healthiest food anyone can eat” to “basically high calorie salty snacks”. And, they can be either!

    Some notes, then:

    • Raw is generally better that not
    • Dry roasted is generally better than the kind with added oils
    • Added salt is neither necessary nor good

    Quick tip: if “roasted salted” are the cheapest or most convenient to buy, you can at least mitigate that by soaking them in warm water for 5 minutes, before rinsing and (if you don’t want wet nuts) drying.

    You may be wondering: who does want wet nuts? And the answer is, if for example you’re making a delicious cashew and chickpea balti, the fact you didn’t dry them before throwing them in won’t make a difference.

    Now, let’s do a quick run-down; we don’t usually do “listicles” but it seemed a good format here, so we’ve picked a top 5 for nutritional potency:

    Almonds

    We may have a bias. We accept it. But almonds are also one of the healthiest nuts around, and generally considered by most popular metrics the healthiest.

    Not only are they high in protein, healthy fat, fiber, vitamins, and minerals, but they’re even a natural prebiotic that increases the populations of healthy gut bacteria, while simultaneously keeping down the populations of gut pathogens—what more can we ask of a nut?

    Read more: Prebiotic effects of almonds and almond skins on intestinal microbiota in healthy adult humans

    Pistachios

    Not only are these super tasty and fun to eat (and mindful eating is all but guaranteed, as shelling them by hand slows us down and makes us more likely to eat them one at a time rather than by the handful), but also they contain lots of nutrients and are lower in calories than most nuts, so they’re a great option for anyone who’d like to eat more nuts but is doing a calorie-controlled diet and doesn’t want to have half a day’s calories in a tiny dish of nuts.

    See: Effects of Pistachio Consumption in a Behavioral Weight Loss Intervention on Weight Change, Cardiometabolic Factors, and Dietary Intake

    Walnuts

    Popularly associated with brain health (perhaps easy to remember because of their appearance), they really are good for the brain:

    Check it out: Beneficial Effects of Walnuts on Cognition and Brain Health

    Cashews

    A personal favorite of this writer for their versatility in cooking, food prep, or just as a snack, they also do wonders for metabolic health:

    Learn more: The Effect of Cashew Nut on Cardiovascular Risk Factors and Blood Pressure: A Systematic Review and Meta-analysis

    Brazil nuts

    The most exciting thing about these nuts is that they’re an incredibly potent source of selenium, which is important not just for hair/skin/nails as popularly marketed, but also for thyroid hormone production and DNA synthesis.

    But don’t eat too many, because selenium is definitely one of those “you can have too much of a good thing” nutrients, and selenium poisoning can make your hair (however beautiful and shiny it got because of the selenium) fall out if you take too much.

    Know the numbers: Brazil nuts and selenium—health benefits and risks

    Bottom line on nuts:

    • Nuts are a great and healthful part of almost anyone’s diet
      • Obviously, if you have a nut allergy, then we’re sorry; this one won’t have helped you so much
    • Almonds are one of the most healthful nuts out there
    • Brazil nuts are incredibly potent, to the point where moderation is recommended
    • A handful of mixed nuts per day is a very respectable option—when it comes to food and health, diversity is almost always good!

  • Practical Optimism – by Dr. Sue Varma

    We’ve written before about how to get your brain onto a more positive track (without toxic positivity), but there’s a lot more to be said than we can fit into an article, so here’s a whole book packed full with usable advice.

    The subtitle claims “the art, science, and practice of…”, but mostly it’s the science of. If there’s art to be found here, then this reviewer missed it, and as for the practice of, well, that’s down to the reader, of course.

    However, it is easy to use the contents of this book to translate science into practice without difficulty.

    If you’re a fan of acronyms, initialisms, and other mnemonics (such as the rhyming “Name, Claim, Tame, and Reframe”), then you’ll love this book as they come thick and fast throughout, and they contribute to the overall ease of application of the ideas within.

    The writing style is conversational but with enough clinical content that one never forgets who is speaking—not in the egotistical way that some authors do, but rather, just, she has a lot of professional experience to share and it shows.

    Bottom line: if you’d like to be more optimistic without delving into the delusional, this book can really help a lot with that (in measurable ways, no less!).

    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.

    Once again proving that burgers do not have to be unhealthy, this one’s a nutritional powerhouse full of protein, fiber, vitamins, and minerals, as well as healthy fats and extra health-giving spices.

    You will need

    • 1 can black beans, drained and rinsed (or 1 cup same, cooked, drained, and rinsed)
    • 3 oz walnuts (if allergic, substitute with pumpkin seeds)
    • 1 tbsp chia seeds
    • 1 tbsp flax seeds
    • ½ red onion, finely chopped
    • 1 small eggplant, diced small (e.g. ½” cubes or smaller)
    • 1 small carrot, grated
    • 3 tbsp finely chopped cilantro (or if you have the “this tastes like soap” gene, then substitute with parsley)
    • 1 tbsp lemon juice
    • 1 jalapeño pepper, finely chopped (adjust per heat preferences)
    • ¼ bulb garlic, crushed
    • 2 tsp black pepper
    • 1 tsp smoked paprika
    • 1 tsp cayenne pepper (adjust per heat preferences)
    • ½ tsp MSG or 1 tsp low-sodium salt
    • Burger buns (you can use our Delicious Quinoa Avocado Bread recipe if you like)

    For the guacamole:

    • 1 large ripe avocado, pitted, skinned, and chopped
    • 1 tbsp lime juice
    • 1 tomato, finely chopped
    • ¼ red onion, finely chopped
    • ¼ bulb garlic, crushed
    • 1 tsp red chili pepper flakes (adjust per heat preferences)

    Method

    (we suggest you read everything at least once before doing anything)

    1) Process the walnuts, chia seeds, and flax seeds in a food processor/blender, until they become a coarse mixture. Set aside.

    2) Heat a little oil in a skillet, and fry the red onion, aubergine, and carrot for 5 minutes stirring frequently, then add the garlic and jalapeño and stir for a further 1 minute. Set aside.

    3) Combine both mixtures you set aside with the rest of the ingredients from the burger section of the recipe, except the buns, and process them in the food processor on a low setting if possible, until you have a coarse mixture—you still want some texture, not a paste.

    4) Shape into patties; this recipe gives for 4 large patties or 8 small ones. When you’ve done this, put them in the fridge for at least 30 minutes, to firm up.

    5) While you wait, make the guacamole by mashing the avocado with the lime juice, and then stirring into the onion, tomato, garlic, and pepper.

    6) Cook the patties; you can do this on the grill, in a skillet, or in the oven, per your preference. Grilling or frying should take about 5 minutes on each side, give or take the size and shape of the patties. Baking in the oven should take 20–30 minutes at 400℉ / 200℃ turning over halfway through, but keep an eye on them, because again, the size and shape of the patties will affect this. You may be wondering: aren’t they all going to be patty-shaped? And yes, but for example a wide flat patty will cook more quickly than the same volume of burger mixture in a taller less wide patty.

    7) Assemble! We recommend the order: bottom bun, guacamole, burger patty, any additional toppings you want to add (e.g. more salad, pickles, etc), top bun:

    Enjoy!

  • Stay away from collarium sunbeds to avoid the big risk of collapsing with a bad tan.

    What are ‘collarium’ sunbeds? Here’s why you should stay away

    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.

    Reports have recently emerged that solariums, or sunbeds – largely banned in Australia because they increase the risk of skin cancer – are being rebranded as “collarium” sunbeds (“coll” being short for collagen).

    Commercial tanning and beauty salons in Queensland, New South Wales and Victoria are marketing collariums, with manufacturers and operators claiming they provide a longer lasting tan and stimulate collagen production, among other purported benefits.

    A collarium sunbed emits both UV radiation and a mix of visible wavelength colours to produce a pink or red light. Like an old-school sunbed, the user lies in it for ten to 20 minute sessions to quickly develop a tan.

    But as several experts have argued, the providers’ claims about safety and effectiveness don’t stack up.

    Why were sunbeds banned?

    Commercial sunbeds have been illegal across Australia since 2016 (except for in the Northern Territory) under state-based radiation safety laws. It’s still legal to sell and own a sunbed for private use.

    Their dangers were highlighted by young Australians including Clare Oliver who developed melanoma after using sunbeds. Oliver featured in the No Tan Is Worth Dying For campaign and died from her melanoma at age 26 in 2007.

    Sunbeds lead to tanning by emitting UV radiation – as much as six times the amount of UV we’re exposed to from the summer sun. When the skin detects enough DNA damage, it boosts the production of melanin, the brown pigment that gives you the tanned look, to try to filter some UV out before it hits the DNA. This is only partially successful, providing the equivalent of two to four SPF.

    Essentially, if your body is producing a tan, it has detected a significant amount of DNA damage in your skin.

    Research shows people who have used sunbeds at least once have a 41% increased risk of developing melanoma, while ten or more sunbed sessions led to a 100% increased risk.

    In 2008, Australian researchers estimated that each year, sunbeds caused 281 cases of melanoma, 2,572 cases of squamous cell carcinoma (another common type of skin cancer), and $3 million in heath-care costs, mostly to Medicare.

    How are collarium sunbeds supposed to be different?

    Australian sellers of collarium sunbeds imply they are safe, but their machine descriptions note the use of UV radiation, particularly UVA.

    UVA is one part of the spectrum of UV radiation. It penetrates deeper into the skin than UVB. While UVB promotes cancer-causing mutations by discharging energy straight into the DNA strand, UVA sets off damage by creating reactive oxygen species, which are unstable compounds that react easily with many types of cell structures and molecules. These damage cell membranes, protein structures and DNA.

    Evidence shows all types of sunbeds increase the risk of melanoma, including those that use only UVA.

    Some manufacturers and clinics suggest the machine’s light spectrum increases UV compatibility, but it’s not clear what this means. Adding red or pink light to the mix won’t negate the harm from the UV. If you’re getting a tan, you have a significant amount of DNA damage.

    Collagen claims

    One particularly odd claim about collarium sunbeds is that they stimulate collagen.

    Collagen is the main supportive tissue in our skin. It provides elasticity and strength, and a youthful appearance. Collagen is constantly synthesised and broken down, and when the balance between production and recycling is lost, the skin loses strength and develops wrinkles. The collagen bundles become thin and fragmented. This is a natural part of ageing, but is accelerated by UV exposure.

    Sun-damaged skin and sun-protected skin from the same person, and the microscopic image of each showing how the collagen bundles have been thinned out in the sun-damaged skin.
    Sun-protected skin (top) has thick bands of pink collagen (arrows) in the dermis, as seen on microscopic examination. Chronically sun-damaged skin (bottom) has much thinner collagen bands.
    Katie Lee/UQ

    The reactive oxygen species generated by UVA light damage existing collagen structures and kick off a molecular chain of events that downgrades collagen-producing enzymes and increases collagen-destroying enzymes. Over time, a build-up of degraded collagen fragments in the skin promotes even more destruction.

    While there is growing evidence red light therapy alone could be useful in wound healing and skin rejuvenation, the UV radiation in collarium sunbeds is likely to undo any benefit from the red light.

    What about phototherapy?

    There are medical treatments that use controlled UV radiation doses to treat chronic inflammatory skin diseases like psoriasis.

    The anti-collagen effects of UVA can also be used to treat thickened scars and keloids. Side-effects of UV phototherapy include tanning, itchiness, dryness, cold sore virus reactivation and, notably, premature skin ageing.

    These treatments use the minimum exposure necessary to treat the condition, and are usually restricted to the affected body part to minimise risks of future cancer. They are administered under medical supervision and are not recommended for people already at high risk of skin cancer, such as people with atypical moles.

    So what happens now?

    It looks like many collariums are just sunbeds rebranded with red light. Queensland Health is currently investigating whether these salons are breaching the state’s Radiation Safety Act, and operators could face large fines.

    As the 2024 Australians of the Year – melanoma treatment pioneers Georgina Long and Richard Scolyer – highlighted in their acceptance speech, “there is nothing healthy about a tan”, and we need to stop glamorising tanning.

    However, if you’re desperate for the tanned look, there is a safer and easy way to get one – out of a bottle or by visiting a salon for a spray tan.The Conversation

  • Growing Young – by Marta Zaraska

    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 will be a slightly mixed review, but we think the book has more than enough of value to make it a very worthwhile read.

    The premise of the book is that, as the subtitle suggests, positive social qualities increase personal longevity.

    Author (and science journalist) Marta Zaraska looks at a lot of research to back this up, and also did a lot of travelling and digging into stories. This is of great value, because she notes where a lot of misconceptions have arisen.

    To give one example, it’s commonly noted that marriage (or as-though-marriage life partnerships) is generally* associated with longer life.

    *Statistics suggest that marriage-related longevity is enjoyed by men married to women, and people in same-sex marriages regardless of gender, but is not so much the case for women married to men.

    However! Zaraska notes a factor she learned from Gottman’s research (yes, that Gottman), that what matters is not the official status of a relationship, so much as the sense of secure lifelong commitment to it.

    These kinds of observations (throughout the book) add an extra layer beyond “common wisdom”, and allow us to better understand what’s really going on. The book’s main weaknesses, meanwhile, are twofold:

    • The author is (in this reviewer’s opinion) unduly dismissive of physical health lifestyle factors such as diet and exercise, because they “only” account for a similar bonus to healthy longevity.
    • Like many, she does not always consider where correlation might not mean causation. For example, she cites that volunteering free time increases healthspan by 22%, but neglects to note that perhaps it is having the kind of socioeconomic situation that allows one free time to volunteer, that gives the benefit.

    Bottom line: the book has its flaws, but we think that only serves to make it more engaging. After all, reading should not be a purely passive activity! Zaraska’s well-studied insights give plenty of pointers for tweaking the social side of anyone’s quest for healthy longevity.
