When trying to lose weight, it’s natural to want to see quick results. So when the number on the scales drops rapidly, it seems like we’re on the right track.

But as with many things related to weight loss, there’s a flip side: rapid weight loss can result in a significant loss of muscle mass, as well as fat.

So how you can tell if you’re losing too much muscle and what can you do to prevent it?

Why does muscle mass matter?

Muscle is an important factor in determining our metabolic rate: how much energy we burn at rest. This is determined by how much muscle and fat we have. Muscle is more metabolically active than fat, meaning it burns more calories.

When we diet to lose weight, we create a calorie deficit, where our bodies don’t get enough energy from the food we eat to meet our energy needs. Our bodies start breaking down our fat and muscle tissue for fuel.

A decrease in calorie-burning muscle mass slows our metabolism. This quickly slows the rate at which we lose weight and impacts our ability to maintain our weight long term.

How to tell you’re losing too much muscle

Unfortunately, measuring changes in muscle mass is not easy.

The most accurate tool is an enhanced form of X-ray called a dual-energy X-ray absorptiometry (DXA) scan. The scan is primarily used in medicine and research to capture data on weight, body fat, muscle mass and bone density.

But while DEXA is becoming more readily available at weight-loss clinics and gyms, it’s not cheap.

There are also many “smart” scales available for at home use that promise to provide an accurate reading of muscle mass percentage.

However, the accuracy of these scales is questionable. Researchers found the scales tested massively over- or under-estimated fat and muscle mass.

Fortunately, there are three free but scientifically backed signs you may be losing too much muscle mass when you’re dieting.

1. You’re losing much more weight than expected each week

Losing a lot of weight rapidly is one of the early signs that your diet is too extreme and you’re losing too much muscle.

Rapid weight loss (of more than 1 kilogram per week) results in greater muscle mass loss than slow weight loss.

Slow weight loss better preserves muscle mass and often has the added benefit of greater fat mass loss.

One study compared people in the obese weight category who followed either a very low-calorie diet (500 calories per day) for five weeks or a low-calorie diet (1,250 calories per day) for 12 weeks. While both groups lost similar amounts of weight, participants following the very low-calorie diet (500 calories per day) for five weeks lost significantly more muscle mass.

2. You’re feeling tired and things feel more difficult

It sounds obvious, but feeling tired, sluggish and finding it hard to complete physical activities, such as working out or doing jobs around the house, is another strong signal you’re losing muscle.

Research shows a decrease in muscle mass may negatively impact your body’s physical performance.

3. You’re feeling moody

Mood swings and feeling anxious, stressed or depressed may also be signs you’re losing muscle mass.

Research on muscle loss due to ageing suggests low levels of muscle mass can negatively impact mental health and mood. This seems to stem from the relationship between low muscle mass and proteins called neurotrophins, which help regulate mood and feelings of wellbeing.

So how you can do to maintain muscle during weight loss?

Fortunately, there are also three actions you can take to maintain muscle mass when you’re following a calorie-restricted diet to lose weight.

1. Incorporate strength training into your exercise plan

While a broad exercise program is important to support overall weight loss, strength-building exercises are a surefire way to help prevent the loss of muscle mass. A meta-analysis of studies of older people with obesity found resistance training was able to prevent almost 100% of muscle loss from calorie restriction.

Relying on diet alone to lose weight will reduce muscle along with body fat, slowing your metabolism. So it’s essential to make sure you’ve incorporated sufficient and appropriate exercise into your weight-loss plan to hold onto your muscle mass stores.

But you don’t need to hit the gym. Exercises using body weight – such as push-ups, pull-ups, planks and air squats – are just as effective as lifting weights and using strength-building equipment.

Encouragingly, moderate-volume resistance training (three sets of ten repetitions for eight exercises) can be as effective as high-volume training (five sets of ten repetitions for eight exercises) for maintaining muscle when you’re following a calorie-restricted diet.

2. Eat more protein

Foods high in protein play an essential role in building and maintaining muscle mass, but research also shows these foods help prevent muscle loss when you’re following a calorie-restricted diet.

But this doesn’t mean just eating foods with protein. Meals need to be balanced and include a source of protein, wholegrain carb and healthy fat to meet our dietary needs. For example, eggs on wholegrain toast with avocado.

3. Slow your weight loss plan down

When we change our diet to lose weight, we take our body out of its comfort zone and trigger its survival response. It then counteracts weight loss, triggering several physiological responses to defend our body weight and “survive” starvation.

Our body’s survival mechanisms want us to regain lost weight to ensure we survive the next period of famine (dieting). Research shows that more than half of the weight lost by participants is regained within two years, and more than 80% of lost weight is regained within five years.

However, a slow and steady, stepped approach to weight loss, prevents our bodies from activating defence mechanisms to defend our weight when we try to lose weight.

Ultimately, losing weight long-term comes down to making gradual changes to your lifestyle to ensure you form habits that last a lifetime.

  • We’re only using a fraction of health workers’ skills. This needs to change

    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.

    Roles of health professionals are still unfortunately often stuck in the past. That is, before the shift of education of nurses and other health professionals into universities in the 1980s. So many are still not working to their full scope of practice.

    There has been some expansion of roles in recent years – including pharmacists prescribing (under limited circumstances) and administering a wider range of vaccinations.

    But the recently released paper from an independent Commonwealth review on health workers’ “scope of practice” identifies the myriad of barriers preventing Australians from fully benefiting from health professionals’ skills.

    These include workforce design (who does what, where and how roles interact), legislation and regulation (which often differs according to jurisdiction), and how health workers are funded and paid.

    There is no simple quick fix for this type of reform. But we now have a sensible pathway to improve access to care, using all health professionals appropriately.

    A new vision for general practice

    I recently had a COVID booster. To do this, I logged onto my general practice’s website, answered the question about what I wanted, booked an appointment with the practice nurse that afternoon, got jabbed, was bulk-billed, sat down for a while, and then went home. Nothing remarkable at all about that.

    But that interaction required a host of facilitating factors. The Victorian government regulates whether nurses can provide vaccinations, and what additional training the nurse requires. The Commonwealth government has allowed the practice to be paid by Medicare for the nurse’s work. The venture capitalist practice owner has done the sums and decided allocating a room to a practice nurse is economically rational.

    The future of primary care is one involving more use of the range of health professionals, in addition to GPs.

    It would be good if my general practice also had a physiotherapist, who I could see if I had back pain without seeing the GP, but there is no Medicare rebate for this. This arrangement would need both health professionals to have access to my health record. There also needs to be trust and good communication between the two when the physio might think the GP needs to be alerted to any issues.

    This vision is one of integrated primary care, with health professionals working in a team. The nurse should be able to do more than vaccination and checking vital signs. Do I really need to see the GP every time I need a prescription renewed for my regular medication? This is the nub of the “scope of practice” issue.

    How about pharmacists?

    An integrated future is not the only future on the table. Pharmacy owners especially have argued that pharmacists should be able to practise independently of GPs, prescribing a limited range of medications and dispensing them.

    This will inevitably reduce continuity of care and potentially create risks if the GP is not aware of what other medications a patient is using.

    But a greater role for pharmacists has benefits for patients. It is often easier and cheaper for the patient to see a pharmacist, especially as bulk billing rates fall, and this is one of the reasons why independent pharmacist prescribing is gaining traction.

    Pharmacists explains something to a patient
    It’s often easier for a patient to see a pharmacist than a GP. PeopleImages.com – Yuri A/Shutterstock

    Every five years or so the government negotiates an agreement with the Pharmacy Guild, the organisation of pharmacy owners, about how much pharmacies will be paid for dispensing medications and other services. These agreements are called “Community Pharmacy Agreements”. Paying pharmacists independent prescribing may be part of the next agreement, the details of which are currently being negotiated.

    GPs don’t like competition from this new source, even though there will be plenty of work around for GPs into the foreseeable future. So their organisations highlight the risks of these changes, reopening centuries old turf wars dressed up as concerns about safety and risk.

    Who pays for all this?

    Funding is at the heart of disputes about scope of practice. As with many policy debates, there is merit on both sides.

    Clearly the government must increase its support for comprehensive general practice. Existing funding of fee-for-service medical benefits payments must be redesigned and supplemented by payments that allow practices to engage a range of other health professionals to create health-care teams.

    This should be the principal direction of primary care reform, and the final report of the scope of practice review should make that clear. It must focus on the overall goal of better primary care, rather than simply the aspirations of individual health professionals, and working to a professional’s full scope of practice in a team, not a professional silo.

    In parallel, governments – state and federal – must ensure all health professionals are used to their best of their abilities. It is a waste to have highly educated professionals not using their skills fully. New funding arrangements should facilitate better access to care from all appropriately qualified health professionals.

    In the case of prescribing, it is possible to reconcile the aspirations of pharmacists and the concerns of GPs. New arrangements could be that pharmacists can only renew medications if they have agreements with the GP and there is good communication between them. This may be easier in rural and suburban areas, where the pharmacists are better known to the GPs.

    The second issues paper points to the complexity of achieving scope of practice reforms. However, it also sets out a sensible path to improve access to care using all health professionals appropriately.

  • Red Light, Go!

    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.

    Casting Yourself In A Healthier Light

    In Tuesday’s newsletter, we asked you for your opinion of red light therapy (henceforth: RLT), and got the above-depicted, below-described, set of responses:

    • About 51% said “I have no idea whether light therapy works or not”
    • About 24% said “Red light therapy is a valuable skin rejuvenation therapy”
    • About 23% said “I have not previously heard of red light therapy”
    • One (1) person said: “Red light therapy is a scam to sell shiny gadgets”

    A number of subscribers wrote with personal anecdotes of using red light therapy to beneficial effect, for example:

    ❝My husband used red light therapy after surgery on his hand. It did seem to speed healing of the incision and there is very minimal scarring. I would like to know if the red light really helped or if he was just lucky❞

    ~ 10almonds subscriber

    And one wrote to report having observed mixed results amongst friends, per:

    ❝Some people it works, others I’ve seen it breaks them out❞

    ~ 10almonds subscriber

    So, what does the science say?

    RLT rejuvenates skin, insofar as it reduces wrinkles and fine lines: True or False?

    True! This one’s pretty clear-cut, so we’ll just give one example study of many, which found:

    ❝The treated subjects experienced significantly improved skin complexion and skin feeling, profilometrically assessed skin roughness, and ultrasonographically measured collagen density.

    The blinded clinical evaluation of photographs confirmed significant improvement in the intervention groups compared with the control❞

    ~ Dr. Alexander Wunsch & Dr. Karsten Matuschka

    Read in full: A Controlled Trial to Determine the Efficacy of Red and Near-Infrared Light Treatment in Patient Satisfaction, Reduction of Fine Lines, Wrinkles, Skin Roughness, and Intradermal Collagen Density Increase

    RLT helps speed up healing of wounds: True or False?

    True! There is less science for this than the above claim, but the studies that have been done are quite compelling, for example this NASA technology study found that…

    ❝LED produced improvement of greater than 40% in musculoskeletal training injuries in Navy SEAL team members, and decreased wound healing time in crew members aboard a U.S. Naval submarine.❞

    ~ Dr. Harry Whelan et al.

    Read more: Effect of NASA light-emitting diode irradiation on wound healing

    RLT’s benefits are only skin-deep: True or False?

    False, probably, but we’d love to see more science for this, to be sure.

    However, it does look like wavelengths in the near-infrared spectrum reduce the abnormal tau protein and neurofibrillary tangles associated with Alzheimer’s disease, resulting in increased blood flow to the brain, and a decrease in neuroinflammation:

    Would you like to try RLT for yourself?

    There are some contraindications, for example:

    • if you have photosensitivity (for obvious reasons)
    • if you have Lupus (mostly because of the above)
    • if you have hyperthyroidism (because if you use RLT to your neck as well as face, it may help stimulate thyroid function, which in your case is not what you want)

    As ever, please check with your own doctor if you’re not completely sure; we can’t cover all bases here, and cannot speak for your individual circumstances.

    For most people though, it’s very safe, and if you’d like to try it, here’s an example product on Amazon, and by all means do read reviews and shop around for the ideal device for you

    Take care! 😎

  • Stretching for 50+ – by Dr. Karl Knopf

    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.

    Dr. Knopf explores in this book the two-way relationship between aging and stretching (i.e., each can have a large impact on the other). Thinking about stretching in those terms is an important reframe for going into any stretching program. We’d say “after the age of 50”, but honestly, at any age. But this book is written with over-50s in mind, as the title goes.

    There’s an extensive encyclopedic section on stretches per body part, which is exactly as you might expect from any book of this kind. There is also a flexibility self-assessment, so that progress can be measured easily, and so that the reader knows where might need more improvement.

    Perhaps this book’s greatest strength is the section on specialized programs based on things ranging from working to improve symptoms of any chronic conditions you may have (or at least working around them, if outright improvement is not possible by stretching), to your recreational activities of importance to you—so, what kinds of flexibilities will be important to you, and also, what kinds of injury you are most likely to need to avoid.

    Bottom line: if you’re 50 and would like to do more stretching and less aging, then this book can help with that.

  • Feta or Parmesan – 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 feta to parmesan, we picked the parmesan.

    Why?

    It’s close! Looking at the macros, parmesan has more protein and slightly less fat. Of the fat content, parmesan also has slightly less saturated fat, but neither of them are doing great in this category. Still, a relative win for parmesan.

    In the category of vitamins, feta is a veritable vitamin-B-fest with more of vitamins B1, B2, B3, B5, B6, and B9. On the other hand, parmesan has more of vitamins A, B12, and choline. By strength of numbers, this is a win for feta.

    Minerals tell a different story; parmesan has a lot more calcium, copper, iron, magnesium, manganese, phosphorus, potassium, selenium, and zinc. Meanwhile, feta is not higher in any minerals. A clear win for parmesan.

    Both cheeses offer gut-healthy benefits (if consumed regularly in small portions), while neither are great for the heart.

    On balance, we say parmesan wins the day.

  • Fennel vs Artichoke – 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 fennel to artichoke, we picked the artichoke.

    Why?

    Both are great! But artichoke wins on nutritional density.

    In terms of macros, artichoke has more protein and more fiber, for only slightly more carbs.

    Vitamins are another win for artichoke, boasting more of vitamins B1, B2, B3, B5, B6, B9, and choline. Meanwhile, fennel has more of vitamins A, E, and K, which is also very respectable but does allow artichoke a 6:3 lead.

    In the category of minerals, artichoke has a lot more copper, iron, magnesium, manganese, and phosphorus, while fennel has a little more calcium, potassium, and selenium.

    One other relevant factor is that fennel is a moderate appetite suppressant, which may be good or bad depending on your food-related goals.

    All in all though, we say the artichoke wins by virtue of its greater abundance of nutrients!

  • What is a virtual emergency department? And when should you ‘visit’ one?

    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.

    For many Australians the emergency department (ED) is the physical and emblematic front door to accessing urgent health-care services.

    But health-care services are evolving rapidly to meet the population’s changing needs. In recent years, we’ve seen growing use of telephone, video, and online health services, including the national healthdirect helpline, 13YARN (a crisis support service for First Nations people), state-funded lines like 13 HEALTH, and bulk-billed telehealth services, which have helped millions of Australians to access health care on demand and from home.

    The ED is similarly expanding into new telehealth models to improve access to emergency medical care. Virtual EDs allow people to access the expertise of a hospital ED through their phone, computer or tablet.

    All Australian states and the Northern Territory have some form of virtual ED at least in development, although not all of these services are available to the general public at this stage.

    So what is a virtual ED, and when is it appropriate to consider using one?

    How does a virtual ED work?

    A virtual ED is set up to mirror the way you would enter the physical ED front door. First you provide some basic information to administration staff, then you are triaged by a nurse (this means they categorise the level of urgency of your case), then you see the ED doctor. Generally, this all takes place in a single video call.

    In some instances, virtual ED clinicians may consult with other specialists such as neurologists, cardiologists or trauma experts to make clinical decisions.

    A virtual ED is not suitable for managing medical emergencies which would require immediate resuscitation, or potentially serious chest pains, difficulty breathing or severe injuries.

    A virtual ED is best suited to conditions that require immediate attention but are not life-threatening. These could include wounds, sprains, respiratory illnesses, allergic reactions, rashes, bites, pain, infections, minor burns, children with fevers, gastroenteritis, vertigo, high blood pressure, and many more.

    People with these sorts of conditions and concerns may not be able to get in to see a GP straight away and may feel they need emergency advice, care or treatment.

    When attending the ED, they can be subject to long wait times and delayed specialist attention because more serious cases are naturally prioritised. Attending a virtual ED may mean they’re seen by a doctor more quickly, and can begin any relevant treatment sooner.

    From the perspective of the health-care system, virtual EDs are about redirecting unnecessary presentations away from physical EDs, helping them be ready to respond to emergencies. The virtual ED will not hesitate in directing callers to come into the physical ED if staff believe it is an emergency.

    The doctor in the virtual ED may also direct the patient to a GP or other health professional, for example if their condition can’t be assessed visually, or if they need physical treatment.

    The results so far

    Virtual EDs have developed significantly over the past three years, predominantly driven by the COVID pandemic. We are now starting to slowly see assessments of these services.

    A recent evaluation my colleagues and I did of Queensland’s Metro North Virtual ED found roughly 30% of calls were directed to the physical ED. This suggests 70% of the time, cases could be managed effectively by the virtual ED.

    Preliminary data from a Victorian virtual ED indicates it curbed a similar rate of avoidable ED presentations – 72% of patients were successfully managed by the virtual ED alone. A study on the cost-effectiveness of another Victorian virtual ED suggested it has the potential to generate savings in health-care costs if it prevents physical ED visits.

    Only 1.2% of people assessed in Queensland’s Metro North Virtual ED required unexpected hospital admission within 48 hours of being “discharged” from the virtual ED. None of these cases were life-threatening. This indicates the virtual ED is very safe.

    The service experienced an average growth rate of 65% each month over a two-year evaluation period, highlighting increasing demand and confidence in the service. Surveys suggested clinicians also view the virtual ED positively.

    What now?

    We need further research into patient outcomes and satisfaction, as well as the demographics of those using virtual EDs, and how these measures compare to the physical ED across different triage categories.

    There are also challenges associated with virtual EDs, including around technology (connection and skills among patients and health professionals), training (for health professionals) and the importance of maintaining security and privacy.

    Nonetheless, these services have the potential to reduce congestion in physical EDs, and offer greater convenience for patients.

    Eligibility differs between different programs, so if you want to use a virtual ED, you may need to check you are eligible in your jurisdiction. Most virtual EDs can be accessed online, and some have direct phone numbers.
