Good news: midlife health is about more than a waist measurement. Here’s why

You’re not in your 20s or 30s anymore and you know regular health checks are important. So you go to your GP. During the appointment they measure your waist. They might also check your weight. Looking concerned, they recommend some lifestyle changes.
GPs and health professionals commonly measure waist circumference as a vital sign for health. This is a better indicator than body mass index (BMI) of the amount of intra-abdominal fat. This is the really risky fat around and within the organs that can drive heart disease and metabolic disorders such as type 2 diabetes.
Men are at greatly increased risk of health issues if their waist circumference is greater than 102 centimetres. Women are considered to be at greater risk with a waist circumference of 88 centimetres or more. More than two-thirds of Australian adults have waist measurements that put them at an increased risk of disease. An even better indicator is waist circumference divided by height or waist-to-height ratio.
But we know people (especially women) have a propensity to gain weight around their middle during midlife, which can be very hard to control. Are they doomed to ill health? It turns out that, although such measurements are important, they are not the whole story when it comes to your risk of disease and death.
How much is too much?
Having a waist circumference to height ratio larger than 0.5 is associated with greater risk of chronic disease as well as premature death and this applies in adults of any age. A healthy waist-to-height ratio is between 0.4 to 0.49. A ratio of 0.6 or more places a person at the highest risk of disease.
Some experts recommend waist circumference be routinely measured in patients during health appointments. This can kick off a discussion about their risk of chronic diseases and how they might address this.
Excessive body fat and the associated health problems manifest more strongly during midlife. A range of social, personal and physiological factors come together to make it more difficult to control waist circumference as we age. Metabolism tends to slow down mainly due to decreasing muscle mass because people do less vigorous physical activity, in particular resistance exercise.
For women, hormone levels begin changing in mid-life and this also stimulates increased fat levels particularly around the abdomen. At the same time, this life phase (often involving job responsibilities, parenting and caring for ageing parents) is when elevated stress can lead to increased cortisol which causes fat gain in the abdominal region.
Midlife can also bring poorer sleep patterns. These contribute to fat gain with disruption to the hormones that control appetite.
Finally, your family history and genetics can make you predisposed to gaining more abdominal fat.
Why the waist?
This intra-abdominal or visceral fat is much more metabolically active (it has a greater impact on body organs and systems) than the fat under the skin (subcutaneous fat).
Visceral fat surrounds and infiltrates major organs such as the liver, pancreas and intestines, releasing a variety of chemicals (hormones, inflammatory signals, and fatty acids). These affect inflammation, lipid metabolism, cholesterol levels and insulin resistance, contributing to the development of chronic illnesses.
The issue is particularly evident during menopause. In addition to the direct effects of hormone changes, declining levels of oestrogen change brain function, mood and motivation. These psychological alterations can result in reduced physical activity and increased eating – often of comfort foods high in sugar and fat.
But these outcomes are not inevitable. Diet, exercise and managing mental health can limit visceral fat gains in mid-life. And importantly, the waist circumference (and ratio to height) is just one measure of human health. There are so many other aspects of body composition, exercise and diet. These can have much larger influence on a person’s health.
Muscle matters
The quantity and quality of skeletal muscle (attached to bones to produce movement) a person has makes a big difference to their heart, lung, metabolic, immune, neurological and mental health as well as their physical function.
On current evidence, it is equally or more important for health and longevity to have higher muscle mass and better cardiorespiratory (aerobic) fitness than waist circumference within the healthy range.
So, if a person does have an excessive waist circumference, but they are also sedentary and have less muscle mass and aerobic fitness, then the recommendation would be to focus on an appropriate exercise program. The fitness deficits should be addressed as priority rather than worry about fat loss.
Conversely, a person with low visceral fat levels is not necessarily fit and healthy and may have quite poor aerobic fitness, muscle mass, and strength. The research evidence is that these vital signs of health – how strong a person is, the quality of their diet and how well their heart, circulation and lungs are working – are more predictive of risk of disease and death than how thin or fat a person is.
For example, a 2017 Dutch study followed overweight and obese people for 15 years and found people who were very physically active had no increased heart disease risk than “normal weight” participants.
Getting moving is important advice
Physical activity has many benefits. Exercise can counter a lot of the negative behavioural and physiological changes that are occurring during midlife including for people going through menopause.
And regular exercise reduces the tendency to use food and drink to help manage what can be a quite difficult time in life.
Measuring your waist circumference and monitoring your weight remains important. If the measures exceed the values listed above, then it is certainly a good idea to make some changes. Exercise is effective for fat loss and in particular decreasing visceral fat with greater effectiveness when combined with dietary restriction of energy intake. Importantly, any fat loss program – whether through drugs, diet or surgery – is also a muscle loss program unless resistance exercise is part of the program. Talking about your overall health with a doctor is a great place to start.
Accredited exercise physiologists and accredited practising dietitians are the most appropriate allied health professionals to assess your physical structure, fitness and diet and work with you to get a plan in place to improve your health, fitness and reduce your current and future health risks.

Correct An Upper Spine Hump (Simple Stretch & Exercise)
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.
Generally called a neck hump in this video, it can be in the cervical (neck) vertebrae or it can be in the thoracic (upper back) vertebrae. It’s also known as a dowager’s hump, buffalo hump, or kyphosis.
However, it can be fixed:
What to do
First understand the cause: it generally comes from poor posture, especially from prolonged desk work or phone use.
With that in mind…
- Posture adjustments: lean back in a chair to counter gravity’s pull on your head. Avoid slumping; keep your head aligned with your spine.
- Stretching: lie flat on the floor without pillows to restore spinal alignment. Gradually reduce pillow height during sleep to decrease neck hyperflexion.
- Neck retraction: pull chin straight back while keeping your eyes looking forwards. Hold for 15 seconds, gradually increasing to 60 seconds. Perform 10 repetitions, resting between sets.
- Strengthening: lean forward and pull the chin back against gravity. Hold, or repeat for 10 repetitions. Over time, increase duration to a minute.

Cynthia’s Thoughts on Intermittent Fasting
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 Myth of Breakfast and Snacking
Here at 10almonds we love addressing misconceptions in the health world.
When it comes to eating habits and fasting, we’ve written our own pieces on how to break your fast (otherwise known as break-fast, or breakfast), alongside a general breakdown of intermittent fasting, and a much-requested piece on fasting specifically for women.
Cynthia Thurlow, though, instead of just writing a few articles, has dedicated the majority of her working years to intermittent fasting and, in her TEDx talk (below), makes a strong argument challenging the long-held belief that breakfast is the most important meal of the day.
Cynthia Thurlow’s Two Main Points
Thurlow argues that it’s not what you eat but when you eat that has a more profound impact on health and aging. And she argues this is crucial regardless of your age.
Complementing her views on fasting are her views on snacking; she argues that snacking all day long is outdated advice and can overtax the digestive system, leading to various health issues.
Practical Tips for Starting Intermittent Fasting
To begin intermittent fasting, Thurlow suggests starting with a 12-13 hour fasting window and gradually increasing it to 16 hours.
In terms of food choice, she recommends eating whole, unprocessed foods during eating periods as well as staying well-hydrated with water, coffee, or tea.
But you won’t see results immediately; Thurlow advises giving the strategy a solid 30 days to see results and consulting a healthcare provider if there are any existing health conditions.
You can dive deeper and join the 15 million other people who have listened to her thoughts on fasting by watching her TEDx talk below:

Astaxanthin: Super-Antioxidant & Neuroprotectant
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.
Think Pink For Brain Health!
Astaxanthin is a carotenoid that’s found in:
- certain marine microalgae
- tiny crustaceans that eat the algae
- fish (and flamingos!) that eat the crustaceans
Yes, it’s the one that makes things pink.
But it does a lot more than that…
Super-antioxidant
Move over, green tea! Astaxanthin has higher antioxidant activity than most carotenoids. For example, it is 2–5 times more effective than alpha-carotene, lutein, beta-carotene, and lycopene:
Antioxidant activities of astaxanthin and related carotenoids
We can’t claim credit for naming it a super-antioxidant though, because:
Astaxanthin: A super antioxidant from microalgae and its therapeutic potential
Grow new brain cells
Axtaxanthin is a neuroprotectant, but that’s to be expected from something with such a powerful antioxidant ability.
What’s more special to astaxanthin is that it assists continued adult neurogenesis (creation of new brain cells):
❝The unique chemical structure of astaxanthin enables it to cross the blood-brain barrier and easily reach the brain, where it may positively influence adult neurogenesis.
Furthermore, astaxanthin appears to modulate neuroinflammation by suppressing the NF-κB pathway, reducing the production of pro-inflammatory cytokines, and limiting neuroinflammation associated with aging and chronic microglial activation.
By modulating these pathways, along with its potent antioxidant properties, astaxanthin may contribute to the restoration of a healthy neurogenic microenvironment, thereby preserving the activity of neurogenic niches during both normal and pathological aging. ❞
That first part is very important, by the way! There are so many things that our brain needs, and we can eat, but the molecules are unable to pass the blood-brain barrier, meaning they either get wasted, or used elsewhere, or dismantled for their constituent parts. In this case, it zips straight into the brain instead.

(Probably) good for the joints, too
First, astaxanthin got a glowing report in a study we knew not to trust blindly:
…and breathe. What a title that was! But, did you catch why it’s not to be trusted blindly? It was down at the bottom…
❝Conflict of interest statement
NOVAREX Co., Ltd. funded the study. Valensa International provided the FlexPro MD® ingredients, and NOVAREX Co., Ltd. encapsulated the test products (e.g., both FlexPro MD® and placebo)❞
Studies where a supplement company funded the study are not necessarily corrupt, but they can certainly sway publication bias, i.e. the company funds a bunch of studies and then pulls funding from the ones that aren’t going the way it wants.
So instead let’s look at:
Astaxanthin attenuates joint inflammation induced by monosodium urate crystals
and
Astaxanthin ameliorates cartilage damage in experimental osteoarthritis
…which had no such conflicts of interest.
They agree that astaxanthin indeed does the things (attenuates joint inflammation & ameliorates cartilage damage).
However, they are animal studies (rats), so we’d like to see studies with humans to be able to say for sure how much it helps these things.
Summary of benefits
Based on the available research, astaxanthin…
- is indeed a super-antioxidant
- is a neuroprotective agent
- also assists adult neurogenesis
- is probablygood for joints too
How much do I take, and is it safe?
A 2019 safety review concluded:
❝Recommended or approved doses varied in different countries and ranged between 2 and 24 mg.
We reviewed 87 human studies, none of which found safety concerns with natural astaxanthin supplementation, 35 with doses ≥12 mg/day.❞
Source: Astaxanthin: How much is too much? A safety review
In short: for most people, it’s very safe and well-tolerated. If you consume it to an extreme, you will likely turn pink, much as you would turn orange if you did the same thing with carrots. But aside from that, the risks appear to be minimal.
However! If you have a seafood allergy, please take care to get a supplement that’s made from microalgae, not one that’s made from krill or other crustaceans, or from other creatures that eat those.
Where can I get it?
We don’t sell it, but here’s an example product on Amazon, for your convenience
Enjoy!

Anti-Aging Risotto With Mushrooms, White Beans, & Kale
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 risotto is made with millet, which as well as being gluten-free, is high in resistant starch that’s great for both our gut and our blood sugars. Add the longevity-inducing ergothioneine in the shiitake and portobello mushrooms, as well as the well-balanced mix of macro- and micronutrients, polyphenols such as lutein (important against neurodegeneration) not to mention more beneficial phytochemicals in the seasonings, and we have a very anti-aging dish!
You will need
- 3 cups low-sodium vegetable stock
- 3 cups chopped fresh kale, stems removed (put the removed stems in the freezer with the vegetable offcuts you keep for making low-sodium vegetable stock)
- 2 cups thinly sliced baby portobello mushrooms
- 1 cup thinly sliced shiitake mushroom caps
- 1 cup millet, as yet uncooked
- 1 can white beans, drained and rinsed (or 1 cup white beans, cooked, drained, and rinsed)
- ½ cup finely chopped red onion
- ½ bulb garlic, finely chopped
- ¼ cup nutritional yeast
- 1 tbsp balsamic vinegar
- 2 tsp ground black pepper
- 1 tsp white miso paste
- ½ tsp MSG or 1 tsp low-sodium salt
- Extra virgin olive oil
Method
(we suggest you read everything at least once before doing anything)
1) Heat a little oil in a sauté or other pan suitable for both frying and volume-cooking. Fry the onion for about 5 minutes until soft, and then add the garlic, and cook for a further 1 minute, and then turn the heat down low.
2) Add about ¼ cup of the vegetable stock, and stir in the miso paste and MSG/salt.
3) Add the millet, followed by the rest of the vegetable stock. Cover and allow to simmer for 30 minutes, until all the liquid is absorbed and the millet is tender.
4) Meanwhile, heat a little oil to a medium heat in a skillet, and cook the mushrooms (both kinds), until lightly browned and softened, which should only take a few minutes. Add the vinegar and gently toss to coat the mushrooms, before setting side.
5) Remove the millet from the heat when it is done, and gently stir in the mushrooms, nutritional yeast, white beans, and kale. Cover, and let stand for 10 minutes (this will be sufficient to steam the kale in situ).
6) Uncover and fluff the risotto with a fork, sprinkling in the black pepper as you do so.
7) Serve. For a bonus for your tastebuds and blood sugars, drizzle with aged balsamic vinegar.
Enjoy!

Guava vs Passion Fruit – 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 guava to passion fruit, we picked the guava.
Why?
There aren’t many fruits that can beat passion fruit for nutritional density! And even in this case, it wasn’t completely so in every category:
In terms of macros, passion fruit has more carbs and fiber, the ratio of which give it the slightly lower glycemic index. Thus, a modest win for passion fruit in this category.
In the category of vitamins, guava has more of vitamins B1, B5, B6, B9, C, E, and K, while passion fruit has more of vitamins A, B2, and B3. A clear win for guava this time.
When it comes to minerals, it’s a little closer, but: guava has more calcium, copper, manganese, potassium, and zinc, while passion fruit has more iron, magnesium, and phosphorus. So, another win for guava.
Adding up the sections makes for guava winning the day, but by all means enjoy either or both; diversity is good!

Polyphenol Paprika Pepper Penne
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’s easier to promptly prepare than it is to pronounce unprepared! Ok, enough alliteration: this dish is as full of flavor as it is full of antioxidants, and it’s great for digestive health and heart health too.
You will need
- 4 large red bell peppers, diced
- 2 red onions, roughly chopped
- 1 bulb garlic, finely chopped
- 2 cups cherry tomatoes, halved
- 10oz wholemeal penne pasta
- 1 tbsp nutritional yeast
- 1 tbsp smoked paprika
- 1 tbsp black pepper
- Extra virgin olive oil for drizzling
Method
(we suggest you read everything at least once before doing anything)
1) Preheat the oven to 200℃ / 400℉ / Gas mark 6
2) Put the vegetables in a roasting tin; drizzle with oil, sprinkle with the seasonings (nooch, paprika, black pepper), stir well to mix and distribute the seasonings evenly, and roast for 20–25 minutes, stirring/turning occasionally. When the edges begin to caramelize, turn off the heat, but leave to keep warm.
3) Cook the penne al dente (this should take 7–8 minutes in boiling salted water). Rinse in cold water, then pass a kettle of hot water over them to reheat. This process removed starch and lowered the glycemic index, before reheating the pasta so that it’s hot to serve.
4) Place the roasted vegetables in a food processor and blitz for just a few seconds. You want to produce a very chunky sauce—but not just chunks or just sauce.
5) Combine the sauce and pasta to serve immediately.
Enjoy!
