It’s a well-known fact that to lose weight, you either need to eat less or move more. But how many calories do you really need to cut out of your diet each day to lose weight? It may be less than you think.
To determine how much energy (calories) your body requires, you need to calculate your total daily energy expenditure (TDEE). This is comprised of your basal metabolic rate (BMR) – the energy needed to sustain your body’s metabolic processes at rest – and your physical activity level. Many online calculators can help determine your daily calorie needs.
If you reduce your energy intake (or increase the amount you burn through exercise) by 500-1,000 calories per day, you’ll see a weekly weight loss of around one pound (0.45kg).
But studies show that even small calorie deficits (of 100-200 calories daily) can lead to long-term, sustainable weight-loss success. And although you might not lose as much weight in the short-term by only decreasing calories slightly each day, these gradual reductions are more effective than drastic cuts as they tend to be easier to stick with.
Hormonal changes
When you decrease your calorie intake, the body’s BMR often decreases. This phenomenon is known as adaptive thermogenesis. This adaptation slows down weight loss so the body can conserve energy in response to what it perceives as starvation. This can lead to a weight-loss plateau – even when calorie intake remains reduced.
Caloric restriction can also lead to hormonal changes that influence metabolism and appetite. For instance, thyroid hormones, which regulate metabolism, can decrease – leading to a slower metabolic rate. Additionally, leptin levels drop, reducing satiety, increasing hunger and decreasing metabolic rate.
Ghrelin, known as the “hunger hormone”, also increases when caloric intake is reduced, signalling the brain to stimulate appetite and increase food intake. Higher ghrelin levels make it challenging to maintain a reduced calorie diet, as the body constantly feels hungrier.
Insulin, which helps regulate blood sugar levels and fat storage, can improve in sensitivity when we reduce calorie intake. But sometimes, insulin levels decrease instead, affecting metabolism and leading to a reduction in daily energy expenditure. Cortisol, the stress hormone, can also spike – especially when we’re in a significant caloric deficit. This may break down muscles and lead to fat retention, particularly in the stomach.
Lastly, hormones such as peptide YY and cholecystokinin, which make us feel full when we’ve eaten, can decrease when we lower calorie intake. This may make us feel hungrier.
Fortunately, there are many things we can do to address these metabolic adaptations so we can continue losing weight.
Weight loss strategies
Maintaining muscle mass (either through resistance training or eating plenty of protein) is essential to counteract the physiological adaptations that slow weight loss down. This is because muscle burns more calories at rest compared to fat tissue – which may help mitigate decreased metabolic rate.
Gradual caloric restriction (reducing daily calories by only around 200-300 a day), focusing on nutrient-dense foods (particularly those high in protein and fibre), and eating regular meals can all also help to mitigate these hormonal challenges.
But if you aren’t someone who wants to track calories each day, here are some easy strategies that can help you decrease daily calorie intake without thinking too much about it:
1. Portion control: reducing portion sizes is a straightforward way of reducing calorie intake. Use smaller plates or measure serving sizes to help reduce daily calorie intake.
2. Healthy swaps: substituting high-calorie foods with lower-calorie alternatives can help reduce overall caloric intake without feeling deprived. For example, replacing sugary snacks with fruits or swapping soda with water can make a substantial difference to your calorie intake. Fibre-rich foods can also reduce the calorie density of your meal.
3. Mindful eating: practising mindful eating involves paying attention to hunger and fullness cues, eating slowly, and avoiding distractions during meals. This approach helps prevent overeating and promotes better control over food intake.
4. Have some water: having a drink with your meal can increase satiety and reduce total food intake at a given meal. In addition, replacing sugary beverages with water has been shown to reduce calorie intake from sugars.
4. Intermittent fasting: restricting eating to specific windows can reduce your caloric intake and have positive effects on your metabolism. There are different types of intermittent fasting you can do, but one of the easiest types is restricting your mealtimes to a specific window of time (such as only eating between 12 noon and 8pm). This reduces night-time snacking, so is particularly helpful if you tend to get the snacks out late in the evening.
Long-term behavioural changes are crucial for maintaining weight loss. Successful strategies include regular physical activity, continued mindful eating, and periodically being diligent about your weight and food intake. Having a support system to help you stay on track can also play a big role in helping you maintain weight loss.
Modest weight loss of 5-10% body weight in people who are overweight or obese offers significant health benefits, including improved metabolic health and reduced risk of chronic diseases. But it can be hard to lose weight – especially given all the adaptations our body has to prevent it from happening.
Thankfully, small, sustainable changes that lead to gradual weight loss appear to be more effective in the long run, compared with more drastic lifestyle changes.

The Plant Power Doctor
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.
A Prescription For GLOVES
This is Dr. Gemma Newman. She’s a GP (General Practitioner, British equivalent to what is called a family doctor in America), and she realized that she was treating a lot of patients while nobody was actually getting better.
So, she set out to help people actually get better… But how?
The biggest thing
The single biggest thing she recommends is a whole foods plant-based diet, as that’s a starting point for a lot of other things.
Click here for an assortment of short videos by her and other health professionals on this topic!
Specifically, she advocates to “love foods that love you back”, and make critical choices when deciding between ingredients.
Click here to see her recipes and tips (this writer is going to try out some of these!)
What’s this about GLOVES?
We recently reviewed her book “Get Well, Stay Well: The Six Healing Health Habits You Need To Know”, and now we’re going to talk about those six things in more words than we had room for previously.
They are six things that she says we should all try to get every day. It’s a lot simpler than a lot of checklists, and very worthwhile:
Gratitude
May seem like a wishy-washy one to start with, but there’s a lot of evidence for this making a big difference to health, largely on account of how it lowers stress and anxiety. See also:
How To Get Your Brain On A More Positive Track (Without Toxic Positivity)
Love
This is about social connections, mostly. We are evolved to be a social species, and while some of us want/need more or less social interaction than others, generally speaking we thrive best in a community, with all the social support that comes with that. See also:
How To Beat Loneliness & Isolation
Outside
This is about fresh air and it’s about moving and it’s about seeing some green plants (and if available, blue sky), marvelling at the wonder of nature and benefiting in many ways. See also:
Vegetables
We spoke earlier about the whole foods plant-based diet for which she advocates, so this is that. While reducing/skipping meat etc is absolutely a thing, the focus here is on diversity of vegetables; it is best to make a game of seeing how many different ones you can include in a week (not just the same three!). See also:
Three Critical Kitchen Prescriptions
Exercise
At least 150 minutes moderate exercise per week, and some kind of resistance work. It can be calisthenics or something; it doesn’t have to be lifting weights if that’s not your thing! See also:
Resistance Is Useful! (Especially As We Get Older)
Sleep
Quality and quantity. Yes, 7–9 hours, yes, regardless of age. Unless you’re a child or a bodybuilder, in which case make it nearer 12. But for most of us, 7–9. See also:
Why You Probably Need More Sleep

Becoming a Supple Leopard – by Dr. Kelly Starrett and Glen Cordoza
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.
We’ve previously reviewed Dr. Starrett’s other book, “Built To Move“, and now today we’ll review his more famous book!
Why is this one so famous? It’s popularly considered “the Bible of Cross-Fit”, even though it’s not at all marketed as such, and nor does it talk about Cross Fit directly. But: people who are interested in being fit, fast, strong, mobile, stable, and so forth, tend to invest in this book at some point if they are serious.
The book is big, heavy, and textbook-like. This isn’t a quick light read. This is a “study over the course of a year or more while doing your physiotherapy degree” book. And yet, it’s written for the widest audience, and as such, everything is explained from the ground up, so no prior knowledge is expected.
It does have pictures, which are clear and helpful, though the print version is better for this than the Kindle edition.
The subtitle of the book is no lie; it does indeed cover all those things, deeply and at length, for everything musculoskeletal.
Bottom line: this book will seriously improve your knowledge and understanding of all things body mechanics and related body maintenance. If you care to get/remain fit/strong/mobile/etc, this book is a fine cornerstone for such endeavors.

*Metaphorically. Furry metamorphosis is not a side-effect. Suppleness, however, is on offer. Yes, even for you, dear reader!

What’s Lurking In Your Household Air?
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.
As individuals, we can’t do much about the outside air. We can try to spend more time in green spaces* and away from traffic, and we can wear face-masks—as was popular in Tokyo and other such large cities long before the pandemic struck.
*The well-known mental health benefits aside (and contrary to British politician Amber Rudd’s famous assertion in a televised political debate that “clean air doesn’t grow on trees”), clean air comes mostly from trees—their natural process of respiration scrubs not only carbon dioxide, but also pollutants, from the air before releasing oxygen without the pollutants. Neat!

We are fortunate to be living in a world where most of us in industrialized countries can exercise a great degree of control over our home’s climate. But, what to do with all that power?
Temperature
Let’s start with the basics. Outside temperature may vary, but you probably have heating and air conditioning. There’s a simple answer here; the optimal temperature for human comfort and wellbeing is 20℃ / 68℉:
Scientists Identify a Universal Optimal Temperature For Life on Earth
Note: this does not mean that that is the ideal global average temperature, because that would mean the polar caps are completely gone, the methane stored there released, many large cities underwater, currently hot places will be too hot for human life (e.g. outside temperatures above human body temperature), there will be mass extinctions of many kinds of animals and plants, including those we humans require for survival, and a great proliferation of many bugs that will kill us. Basically we need diversity for the planet to survive, arctic through to tropical and yes, even deserts (deserts are important carbon sinks!). The ideal global average temperature is about 14℃ (we currently have about 15℃ and rising).
But, for setting the thermostat in your home, 20℃ / 68℉ is perfect for most people, though down as far as 17℃ / 61℉ is fine too, provided other things such as humidity are in order. In fact, for sleeping, 18℃ / 62℉ is ideal. This is because the cooler temperature is one of the several things that tell our brain it is nighttime now, and thus trigger secretion of melatonin.
If you’re wondering about temperatures and respiratory viruses, by the way, check out:
The Cold Truth About Respiratory Infections: The Pathogens That Came In From The Cold
Humidity
Most people pay more attention to the temperature in their home than the humidity, and the latter is just as important:
❝Conditions that fall outside of the optimal range of 40–60% can have significant impacts on health, including facilitating infectious transmission and exacerbating respiratory diseases.
When humidity is too low, it can cause dryness and irritation of the respiratory tract and skin, making individuals more susceptible to infections.
When humidity is too high, it can create a damp environment that encourages the growth of harmful microorganisms like mould, bacteria, and viruses.❞
~ Dr. Gabriella Guarnieri et al.
So, if your average indoor humidity falls outside of that range, consider getting a humidifier or dehumidifier, to correct it. Example items on Amazon, for your convenience:
Humidity monitor | Humidifier | Dehumidifier
See also, about a seriously underestimated killer:
Pneumonia: Prevention Is Better Than Cure
Now, one last component to deal with, for perfect indoor air:
Pollution
We tend to think of pollution as an outdoors thing, and indeed, the pollution in your home will (hopefully!) be lower than that of a busy traffic intersection. However…
- The air you have inside comes from outside, and that matters if you’re in an urban area
- Even in suburban and rural areas, general atmospheric pollutants will reach you, and if you’ve ever been subject to wildfire smoke, you’ll know that’s no fun either.
- Gas appliances in the home cause indoor pollution, even when carbon monoxide is within levels considered acceptable. This polluting effect is much stronger for open gas flames (such as on gas cookers/stoves, or gas fires), than for closed gas heating systems (such as a gas-powered boiler for central heating).
- Wood stoves/fireplaces are not an improvement, in fact they are worse, and don’t get us started on coal. You should not be breathing these things, and definitely should not be burning them in an enclosed space.
- That air conditioning, humidifier, dehumidifier? They may be great for temperature and humidity, but please clean/change the filter more often than you think is necessary, or things will grow there and then your device will be adding pathogens to the air as it goes.
- Plug-in air-freshening devices? They may smell clean, but they are effectively spraying cleaning fluids into your lungs. So please don’t.
So, what of air purifiers? They can definitely be of benefit. for example:
But watch out! Because if you don’t clean/change the filter regularly, guess what happens! That’s right, it’ll be colonized with bacteria/fungus and then be blowing those at you.
And no, not all of them will be visible to the naked eye:
Is Unnoticed Environmental Mold Harming Your Health?
Taking a holistic approach
The air is a very important factor for the health of your lungs (and thus, for the health of everything that’s fed oxygen by your lungs), but there are more things we can do as well:

America’s Health System Isn’t Ready for the Surge of Seniors With Disabilities
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 number of older adults with disabilities — difficulty with walking, seeing, hearing, memory, cognition, or performing daily tasks such as bathing or using the bathroom — will soar in the decades ahead, as baby boomers enter their 70s, 80s, and 90s.
But the health care system isn’t ready to address their needs.
That became painfully obvious during the covid-19 pandemic, when older adults with disabilities had trouble getting treatments and hundreds of thousands died. Now, the Department of Health and Human Services and the National Institutes of Health are targeting some failures that led to those problems.
One initiative strengthens access to medical treatments, equipment, and web-based programs for people with disabilities. The other recognizes that people with disabilities, including older adults, are a separate population with special health concerns that need more research and attention.
Lisa Iezzoni, 69, a professor at Harvard Medical School who has lived with multiple sclerosis since her early 20s and is widely considered the godmother of research on disability, called the developments “an important attempt to make health care more equitable for people with disabilities.”
“For too long, medical providers have failed to address change in society, changes in technology, and changes in the kind of assistance that people need,” she said.
Among Iezzoni’s notable findings published in recent years:
Most doctors are biased. In survey results published in 2021, 82% of physicians admitted they believed people with significant disabilities have a worse quality of life than those without impairments. Only 57% said they welcomed disabled patients.
“It’s shocking that so many physicians say they don’t want to care for these patients,” said Eric Campbell, a co-author of the study and professor of medicine at the University of Colorado.
While the findings apply to disabled people of all ages, a larger proportion of older adults live with disabilities than younger age groups. About one-third of people 65 and older — nearly 19 million seniors — have a disability, according to the Institute on Disability at the University of New Hampshire.
Doctors don’t understand their responsibilities. In 2022, Iezzoni, Campbell, and colleagues reported that 36% of physicians had little to no knowledge of their responsibilities under the 1990 Americans With Disabilities Act, indicating a concerning lack of training. The ADA requires medical practices to provide equal access to people with disabilities and accommodate disability-related needs.
Among the practical consequences: Few clinics have height-adjustable tables or mechanical lifts that enable people who are frail or use wheelchairs to receive thorough medical examinations. Only a small number have scales to weigh patients in wheelchairs. And most diagnostic imaging equipment can’t be used by people with serious mobility limitations.
Iezzoni has experienced these issues directly. She relies on a wheelchair and can’t transfer to a fixed-height exam table. She told me she hasn’t been weighed in years.
Among the medical consequences: People with disabilities receive less preventive care and suffer from poorer health than other people, as well as more coexisting medical conditions. Physicians too often rely on incomplete information in making recommendations. There are more barriers to treatment and patients are less satisfied with the care they do get.
Egregiously, during the pandemic, when crisis standards of care were developed, people with disabilities and older adults were deemed low priorities. These standards were meant to ration care, when necessary, given shortages of respirators and other potentially lifesaving interventions.
There’s no starker example of the deleterious confluence of bias against seniors and people with disabilities. Unfortunately, older adults with disabilities routinely encounter these twinned types of discrimination when seeking medical care.
Such discrimination would be explicitly banned under a rule proposed by HHS in September. For the first time in 50 years, it would update Section 504 of the Rehabilitation Act of 1973, a landmark statute that helped establish civil rights for people with disabilities.
The new rule sets specific, enforceable standards for accessible equipment, including exam tables, scales, and diagnostic equipment. And it requires that electronic medical records, medical apps, and websites be made usable for people with various impairments and prohibits treatment policies based on stereotypes about people with disabilities, such as covid-era crisis standards of care.
“This will make a really big difference to disabled people of all ages, especially older adults,” said Alison Barkoff, who heads the HHS Administration for Community Living. She expects the rule to be finalized this year, with provisions related to medical equipment going into effect in 2026. Medical providers will bear extra costs associated with compliance.
Also in September, NIH designated people with disabilities as a population with health disparities that deserves further attention. This makes a new funding stream available and “should spur data collection that allows us to look with greater precision at the barriers and structural issues that have held people with disabilities back,” said Bonnielin Swenor, director of the Johns Hopkins University Disability Health Research Center.
One important barrier for older adults: Unlike younger adults with disabilities, many seniors with impairments don’t identify themselves as disabled.
“Before my mom died in October 2019, she became blind from macular degeneration and deaf from hereditary hearing loss. But she would never say she was disabled,” Iezzoni said.
Similarly, older adults who can’t walk after a stroke or because of severe osteoarthritis generally think of themselves as having a medical condition, not a disability.
Meanwhile, seniors haven’t been well integrated into the disability rights movement, which has been led by young and middle-aged adults. They typically don’t join disability-oriented communities that offer support from people with similar experiences. And they don’t ask for accommodations they might be entitled to under the ADA or the 1973 Rehabilitation Act.
Many seniors don’t even realize they have rights under these laws, Swenor said. “We need to think more inclusively about people with disabilities and ensure that older adults are fully included at this really important moment of change.”

The End of Stress – by Don Joseph Goewey
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.
So, we probably know to remember to take a deep breath once in a while, and adopt a “focus on what you can control, rather than what you can’t” attitude. In this book, Goewey covers a lot more.
After an overview of how we have a brain wired for stress, what it does to us, and why we should rewire that, he dives straight into such topics as:
- Letting go of fear—safely!
- Number-crunching the real risks
- Leading with good decisions, and trusting the process
- Actively practicing a peaceful mindset (some very good tips here)
- Transcending shame (and thus sidestepping the stress that it may otherwise bring)
The book brings together a lot of ideas and factors, seamlessly. From scientific data to case studies, to “try this and see”, encouraging us to try certain exercises for ourselves and be surprised at the results.
All in all, this is a great book on not just managing stress, but—as the title suggests—ending it in all and any cases it’s not useful to us. In other words, this book? It is useful to us.

Dietary Changes for Artery Health

It’s Q&A Day at 10almonds!

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
❝How does your diet change clean out your arteries of the bad cholesterol?❞
There’s good news and bad news here, and they can both be delivered with a one-word reply:
Slowly.
Or rather: what’s being cleaned out is mostly not the LDL (bad) cholesterol, but rather, the result of that.
When our diet is bad for cardiovascular health, our arteries get fatty deposits on their walls. Cholesterol gets stuck here too, but that’s not the main physical problem.
Our body’s natural defenses come into action and try to clean it up, but they (for example macrophages, a kind of white blood cell that consumes invaders and then dies, before being recycled by the next part of the system) often get stuck and become part of the buildup (called atheroma), which can lead to atherosclerosis and (if calcium levels are high) hardening of the arteries, which is the worst end of this.
This can then require medical attention, precisely because the body can’t remove it very well—especially if you are still maintaining a heart-unhealthy diet, thus continuing to add to the mess.
However, if it is not too bad yet, yes, a dietary change alone will reverse this process. Without new material being added to the arterial walls, the body’s continual process of rejuvenation will eventually fix it, given time (free from things making it worse) and resources.
In fact, your arteries can be one of the quickest places for your body to make something better or worse, because the blood is the means by which the body moves most things (good or bad) around the body.
All the more reason to take extra care of it, since everything else depends on it!
