Breakfast Time!

In yesterday’s newsletter, we asked you for your health-related opinions on the timings of meals.

But what does the science say?

Quick recap on intermittent fasting first:

Today’s article will rely somewhat on at least a basic knowledge of intermittent fasting, what it is, and how and why it works.

Armed with that knowledge, we can look at when it is good to break the fast (i.e. breakfast) and when it is good to begin the fast (i.e. eat the last meal of the day).

So, if you’d like a quick refresher on intermittent fasting, here it is:

Intermittent Fasting: We Sort The Science From The Hype

And now, onwards!

One should eat breakfast first thing: True or False?

True! Give or take one’s definition of “first thing”. We did a main feature about this previously, and you can read a lot about the science of it, and see links to studies:

The Circadian Rhythm: Far More Than Most People Know

In case you don’t have time to read that now, we’ll summarize the most relevant-to-today’s-article conclusion:

The optimal time to breakfast is around 10am (this is based on getting sunlight around 8:30am, so adjust if this is different for you)

It doesn’t matter when we eat; calories are calories & nutrients are nutrients: True or False?

Broadly False, for practical purposes. Because, indeed calories are calories and nutrients are nutrients at any hour, but the body will do different things with them depending on where we are in the circadian cycle.

For example, this study in the Journal of Nutrition found…

❝Our results suggest that in relatively healthy adults, eating less frequently, no snacking, consuming breakfast, and eating the largest meal in the morning may be effective methods for preventing long-term weight gain.

Eating breakfast and lunch 5-6 h apart and making the overnight fast last 18-19 h may be a useful practical strategy.❞

~ Dr. Hana Kahleova et al.

We should avoid eating too late at night: True or False?

False per se, True in the context of the above. Allow us to clarify:

There is nothing inherently bad about eating late at night; there is no “bonus calorie happy hour” before bed.

However…

If we are eating late at night, that makes it difficult to breakfast in the morning (as is ideal) and still maintain a >16hr fasting window as is optimal, per:

❝the effects of the main forms of fasting, activating the metabolic switch from glucose to fat and ketones (G-to-K), starting 12-16 h after cessation or strong reduction of food intake

~ Dr. Françoise Wilhelmi de Toledo et al.

So in other words: since the benefits of intermittent fasting start at 12 hours into the fast, you’re not going to get them if you’re breakfasting at 10am and also eating in the evening.

Summary:

  • It is best to eat breakfast around 10am, generally (ideally after some sunlight and exercise)
  • While there’s nothing wrong with eating in the evening per se, doing so means that a 10am breakfast will eliminate any fasting benefits you might otherwise get
  • If a “one meal a day, and that meal is breakfast” lifestyle doesn’t suit you, then one possible good compromise is to have a large breakfast, and then a smaller meal in the late afternoon / early evening.

One last tip: the above is good, science-based information. Use it (or don’t), as you see fit. We’re not the boss of you:

  • Maybe you care most about getting the best circadian rhythm benefits, in which case, prioritizing breakfast being a) in the morning and b) the largest meal of the day, is key
  • Maybe you care most about getting the best intermittent fasting benefits, in which case, for many people’s lifestyle, a fine option is skipping eating in the morning, and having one meal in the late afternoon / early evening.

Take care!

  • Laziness Does Not Exist – by Dr. Devon Price

    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.

    Some cultures prize productivity as an ideal above most other things, and it’s certainly so in the US. Not only is this not great for mental health in general, but also—as Dr. Price explains—it’s based on a lie.

    Generally speaking, when a person appears lazy there is something stopping them/you from doing better, and it’s not some mystical unseen force of laziness, not a set character trait, not a moral failing. Rather, the root cause may be physical, psychological, socioeconomic, or something else entirely.

    Those causes can in some cases be overcome (for example, a little CBT can often set aside perfectionist anxiety that results in procrastination), and in some cases they can’t, at least on an individual level (disabilities often stubbornly remain disabling, and societal problems require societal solutions).

    This matters for our mental health in areas well beyond the labor marketplace, of course, and these ideas extend to personal projects and even personal relationships. Whatever it is, if it’s leaving you exhausted, then probably something needs to be changed (even if the something is just “expectations”).

    The book does offer practical solutions to all manner of such situations, improving what can be improved, making easier what can be made easier, and accepting what just needs to be accepted.

    The style of this book is casual yet insightful and deep, easy-reading yet with all the acumen of an accomplished social psychologist.

    Bottom line: if life leaves you exhausted, this book can be the antidote and cure

  • Here’s the latest you need to know about bird flu

    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.

    What you need to know

    • Although bird flu continues to spread in wild birds, livestock, and humans, the risk to the public remains low.
    • The majority of U.S. bird flu cases have been reported in farm workers who had direct contact with infected birds and cattle. Health officials are working to monitor the spread of the virus and improve protections for those most at risk.
    • Recent data suggests that mutations in bird flu viruses could make them more dangerous to humans and potentially increase the risk of a pandemic.
    • On January 6, Louisiana health officials confirmed the first U.S. death from bird flu.

    Throughout 2024, dozens of human cases of H5N1 bird flu were detected as the virus spreads rapidly in livestock. The current risk to humans is low but not nonexistent. Here’s everything you need to know about the current status and future outlook of H5 bird flu in the United States.

    Current U.S. bird flu status (as of January 6, 2025)

    As of January 6, 66 human bird flu cases have been reported in eight states. Over half of all cases are in California. The state’s governor declared a state of emergency as a “proactive” action against bird flu on December 18. 

    On January 6, the Louisiana Department of Health reported the first U.S. bird flu death. The patient, a man over age 65, was previously confirmed to be the first severe bird flu case in the U.S. and the first case linked to backyard flocks. The department emphasized that the risk to the public is low and that no new cases or evidence of human transmission have been detected in the state.

    All but two human bird flu cases this year were in farm workers who were exposed to infected livestock. The exposure source of the remaining cases—one in California and one in Missouri—is unknown. 

    The CDC reported on November 22 that a child in California tested positive for bird flu, the first known pediatric bird flu case in the U.S. However, it is unclear how the child contracted the virus, as they had no known contact with infected animals. 

    To date, there have been no reports of human transmission of bird flu during the current outbreak. Additionally, most human cases have not been severe, and no deaths have been reported. For these reasons, experts are confident that the bird flu risk to humans remains low. 

    “In the short term, there is very little threat,” Dr. Scott Roberts, an infectious diseases specialist with Yale Medicine said. “The risk for the general public is so low,” he emphasized to Yale Medicine.

    How the U.S. is monitoring bird flu 

    The CDC continues to monitor the circulation of bird flu in humans as part of its year-round flu monitoring. The agency is also working to improve protections for farm workers, who are at the highest risk of contracting bird flu.

    In November 2024, the CDC also announced expanded actions and updated guidance for farm workers, including improved access to and training for using personal protective equipment (such as N95 face masks), more rigorous testing procedures, and increased outreach. These updates followed a CDC report finding that 7 percent of participating dairy workers had signs of a recent bird flu infection. A second CDC study, also released in November, found inadequate use of personal protective equipment among dairy workers on farms with bird flu outbreaks. 

    After the H5N1 virus was found in raw milk being sold in California, the U.S. Department of Agriculture announced on December 6 that unpasteurized milk must be tested for bird flu. The USDA order also requires dairy farms with positive bird flu cases to cooperate with health officials in disease surveillance. 

    Is a bird flu pandemic possible?

    In early November, a Canadian teen was hospitalized with bird flu caused by a virus that’s closely related to the H5N1 virus circulating in the U.S. The case has troubled experts for a few reasons. 

    First, it is Canada’s first human bird flu case where the patient was not infected while traveling, and the source of exposure is unknown. Second, the teen experienced severe symptoms and developed a lung infection requiring critical care, raising concern that bird flu infections may be more severe in younger people. 

    The final and biggest concern about the case is that genetic analysis revealed several changes in the virus’s DNA sequence, called mutations, that could potentially make the virus better able to infect humans. Researchers say that two of those mutations could make it easier for the virus to infect humans, and another one may make it easier for the virus to replicate after infecting a human. However, it’s unclear if the changes occurred before or after the teen was infected.

    Scott Hensley, a professor of microbiology at the University of Pennsylvania, told Nature that “this should serve as a warning: this virus has the capacity to switch very quickly into a form that can cause severe disease.”

    Notably, even in this more severe case, there is still no evidence of human transmission, which is necessary for a potential bird flu pandemic. However, the case underscores the risk of new and potentially dangerous mutations emerging as the H5N1 virus continues to spread and multiply. 

    A study published in Science on December 5 found that a genetic change on a protein on the surface of the virus could make it easier for the virus to attach to and infect human cells. But none of the mutations observed in the Canadian case are those identified in the study. 

    Importantly, the researchers stressed that the ability of the virus to attach to a specific part of human cells “is not the only [factor] required for human-to-human transmission of influenza viruses.” 

    How to stay safe

    Most people are not at high risk of being exposed to bird flu. The virus is spreading between animals and from animals to humans through direct contact. The CDC recommends avoiding the consumption of raw milk products and direct contact with wild birds and potentially infected livestock. 

    “Pasteurization kills the bird flu virus and other harmful germs that can be found in raw milk,” says a November 24 California Department of Public Health press release. “CDPH advises consumers not to drink raw milk or eat raw milk products due to the risk of foodborne illnesses.”

    Additionally, although the annual flu shot does not protect against bird flu, getting vaccinated helps prevent infection with seasonal flu and bird flu at the same time. In very rare instances, getting infected by two influenza viruses at the same time can result in a combination of genetic material that produces a new virus. 

    This phenomenon, known as antigenic shift, triggered the 2009 swine flu pandemic.

  • Protein vs Sarcopenia

    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.

    Protein vs Sarcopenia

    This is Dr. Gabrielle Lyon. A medical doctor, she’s board-certified in family medicine, and has also engaged in research and clinical practice in the fields of geriatrics and nutritional sciences.

    A quick note…

    We’re going to be talking a bit about protein metabolism today, and it’s worth noting that Dr. Lyon personally is vehemently against vegetarianism/veganism, and considers red meat to be healthy.

    Scientific consensus on the other hand, holds that vegetarianism and veganism are fine for most people if pursued in an informed and mindful fashion, that white meat and fish are also fine for most people, and red meat is simply not.

    If you’d like a recap on the science of any of that:

    Nevertheless, if we look at the science that she provides, the advice is sound when applied to protein in general and without an undue focus on red meat.

    How much protein is enough?

    In our article linked above, we gave 1–2g/kg/day

    Dr. Lyons gives the more specific 1.6g/kg/day for adults older than 40 (this is where sarcopenia often begins!) and laments that many sources offer 0.8g/kg.

    To be clear, that “per kilogram” means per kilogram of your bodyweight. For Americans, this means dividing lbs by 2.2 to get the kg figure.

    Why so much protein?

    Protein is needed to rebuild not just our muscles, but also our bones, joint tissues, and various other parts of us:

    We Are Such Stuff As Fish Are Made Of

    Additionally, our muscles themselves are important for far more than just moving us (and other things) around.

    As Dr. Lyon explains: sarcopenia, the (usually age-related) loss of muscle mass, does more than just make us frail; it also messes up our metabolism, which in turn messes up… Everything else, really. Because everything depends on that.

    This is because our muscles themselves use a lot of our energy, and/but also store energy as glycogen, so having less of them means:

    • getting a slower metabolism
    • the energy that can’t be stored in muscle tissue gets stored somewhere else (like the liver, and/or visceral fat)

    So, while for example the correlation between maintaining strong muscles and avoiding non-alcoholic fatty liver disease may not be immediately obvious, it is clear when one follows the metabolic trail to its inevitable conclusion.

    Same goes for avoiding diabetes, heart disease, and suchlike, though those things are a little more intuitive.

    How can we get so much protein?

    It can seem daunting at first to get so much protein if you’re not used to it, especially as protein is an appetite suppressant, so you’ll feel full sooner.

    It can especially seem daunting to get so much protein if you’re trying to avoid too many carbs, and here’s where Dr. Lyon’s anti-vegetarianism does have a point: it’s harder to get lean protein without meat/fish.

    That said, “harder” does not mean “impossible” and even she acknowledges that lentils are great for this.

    If you’re not vegetarian or vegan, collagen supplementation is a good way to make up any shortfall, by the way.

    And for everyone, there are protein supplements available if we want them (usually based on whey protein or soy protein)

    Anything else we need to do?

    Yes! Eating protein means nothing if you don’t do any resistance work to build and maintain muscle. This can take various forms, and Dr. Lyon recommends lifting weights and/or doing bodyweight resistance training (calisthenics, Pilates, etc).

    Here are some previous articles of ours, consistent with the above:

    Take care!

  • Sunflower Seeds vs Pumpkin Seeds – Which is Healthier?

    Our Verdict

    When comparing sunflower seeds to pumpkin seeds, we picked the pumpkin seeds.

    Why?

    Both seeds have a good spread of vitamins and minerals, but pumpkin seeds have more. Sunflower seeds come out on top for copper and manganese, but everything else that’s present in either of them (in the category of vitamins and minerals, anyway), pumpkin seeds have more.

    There is one other thing that sunflower seeds have more of than pumpkin seeds, and that’s fat. The fat is mostly of healthy varieties, so it’s not a negative factor, but it does mean that if you’re eating a calorie-controlled diet, you’ll get more bang for your buck (i.e. better micronutrient-to-calorie ratio) if you pick pumpkin seeds.

    If you’re not concerned about fat/calories, and/or you actively want to consume more of those, then sunflower seeds are still a fine choice.

    When it comes down to it, a diverse diet is best, so enjoying both might be the best option of all.

  • Women want to see the same health provider during pregnancy, birth and beyond

    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.

    Hazel Keedle, Western Sydney University and Hannah Dahlen, Western Sydney University

    In theory, pregnant women in Australia can choose the type of health provider they see during pregnancy, labour and after they give birth. But this is often dependent on where you live and how much you can afford in out-of-pocket costs.

    While standard public hospital care is the most common in Australia, accounting for 40.9% of births, the other main options are:

    • GP shared care, where the woman sees her GP for some appointments (15% of births)
    • midwifery continuity of care in the public system, often called midwifery group practice or caseload care, where the woman sees the same midwife of team of midwives (14%)
    • private obstetrician care (10.6%)
    • private midwifery care (1.9%).

    Given the choice, which model would women prefer?

    Our new research, published BMC Pregnancy and Childbirth, found women favoured seeing the same health provider throughout pregnancy, in labour and after they have their baby – whether that’s via midwifery group practice, a private midwife or a private obstetrician.

    Assessing strengths and limitations

    We surveyed 8,804 Australian women for the Birth Experience Study (BESt) and 2,909 provided additional comments about their model of maternity care. The respondents were representative of state and territory population breakdowns, however fewer respondents were First Nations or from culturally or linguistically diverse backgrounds.

    We analysed these comments in six categories – standard maternity care, high-risk maternity care, GP shared care, midwifery group practice, private obstetric care and private midwifery care – based on the perceived strengths and limitations for each model of care.

    Overall, we found models of care that were fragmented and didn’t provide continuity through the pregnancy, birth and postnatal period (standard care, high risk care and GP shared care) were more likely to be described negatively, with more comments about limitations than strengths.

    What women thought of standard maternity care in hospitals

    Women who experienced standard maternity care, where they saw many different health care providers, were disappointed about having to retell their story at every appointment and said they would have preferred continuity of midwifery care.

    Positive comments about this model of care were often about a midwife or doctor who went above and beyond and gave extra care within the constraints of a fragmented system.

    The model of care with the highest number of comments about limitations was high-risk maternity care. For women with pregnancy complications who have their baby in the public system, this means seeing different doctors on different days.

    Some respondents received conflicting advice from different doctors, and said the focus was on their complications instead of their pregnancy journey. One woman in high-risk care noted:

    The experience was very impersonal, their focus was my cervix, not preparing me for birth.

    Why women favoured continuity of care

    Overall, there were more positive comments about models of care that provided continuity of care: private midwifery care, private obstetric care and midwifery group practice in public hospitals.

    Women recognised the benefits of continuity and how this included informed decision-making and supported their choices.

    The model of care with the highest number of positive comments was care from a privately practising midwife. Women felt they received the “gold standard of maternity care” when they had this model. One woman described her care as:

    Extremely personable! Home visits were like having tea with a friend but very professional. Her knowledge and empathy made me feel safe and protected. She respected all of my decisions. She reminded me often that I didn’t need her help when it came to birthing my child, but she was there if I wanted it (or did need it).

    However, this is a private model of care and women need to pay for it. So there are barriers in accessing this model of care due to the cost and the small numbers working in Australia, particularly in regional, rural and remote areas, among other barriers.

    Women who had private obstetricians were also positive about their care, especially among women with medical or pregnancy complications – this type of care had the second-highest number of positive comments.

    This was followed by women who had continuity of care from midwives in the public system, which was described as respectful and supportive.

    However, one of the limitations about continuity models of care is when the woman doesn’t feel connected to her midwife or doctor. Some women who experienced this wished they had the opportunity to choose a different midwife or doctor.

    What about shared care with a GP?

    While shared care between the GP and hospital model of care is widely promoted in the public maternity care system as providing continuity, it had a similar number of negative comments to those who had fragmented standard hospital care.

    Considering there is strong evidence about the benefits of midwifery continuity of care, and this model of care appears to be most acceptable to women, it’s time to expand access so all Australian women can access continuity of care, regardless of their location or ability to pay.

  • Getting to Neutral – by Trevor Moawad

    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 all know that a pessimistic outlook is self-defeating… And yet, toxic positivity can also be a set-up for failure! At some point, reckless faith in the kindly nature of the universe will get crushed, badly. Sometimes that point is a low point in life… sometimes it’s six times a day. But one thing’s for sure: we can’t “just decide everything will go great!” because the world just doesn’t work that way.

    That’s where Trevor Moawad comes in. “Getting to neutral” is not a popular selling point. Everyone wants joy, abundance, and high after high. And neutrality itself is often associated with boredom and soullessness. But, Moawad argues, it doesn’t have to be that way.

    This book’s goal—which it accomplishes well—is to provide a framework for being a genuine realist. What does that mean?

    “I’m not a pessimist; I’m a realist” – every pessimist ever.

    ^Not that. That’s not what it means. What it means instead is:

    1. Hope for the best
    2. Prepare for the worst
    3. Adapt as you go

    …taking care to use past experiences to inform future decisions, but without falling into the trap of thinking that because something happened a certain way before, it always will in the future.

    To be rational, in short. Consciously and actively rational.

    Feel the highs! Feel the lows! But keep your baseline when actually making decisions.

    Bottom line: this book is as much an antidote to pessimism and self-defeat, as it is to reckless optimism and resultant fragility. Highly recommendable.

    Click here to check out “Getting to Neutral” and start creating your best, most reason-based life!

    PS: in this book, Moawad draws heavily from his own experiences of battling adversity in the form of cancer—of which he died, before this book’s publication. A poignant reminder that he was right: we won’t always get the most positive outcome of any given situation, so what matters the most is making the best use of the time we have.
