Obesity kills a lot of people (as does medical neglect and malpractice when it comes to obese patients, but that is another matter), but often the biggest problem is not “too much fat” but rather “too little muscle”. This gets disguised a bit, because these factors often appear in the same people, but it’s a distinction that’s worthy of note.

Dr. Lyon lays out a lot of good hard science in this work, generally in the field of protein metabolism, but also with a keen eye on all manner of blood metrics (triglycerides, LDL/HDL, fasting blood sugars, assorted other biomarkers of metabolic health).

The style of this book is two books in one. It’s a very accessible pop-science book in its primary tone, with an extra layer of precise science and lots of references, for those who wish to dive into that.

In the category of criticism, the diet plan section of the book is rather meat-centric, but the goal of this is protein content, not meat per se, so substitutions can easily be made. That’s just one small section of the book, though, and it’s little enough a downside that even Dr. Mark Hyman (a popular proponent of plant-based nutrition) highly recommends the book.

Bottom line: if you’d like to be less merely fighting decline and more actually becoming healthier as you age, then this book will help you do just that.

  • Could not getting enough sleep increase your risk of type 2 diabetes?

    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.

    Not getting enough sleep is a common affliction in the modern age. If you don’t always get as many hours of shut-eye as you’d like, perhaps you were concerned by news of a recent study that found people who sleep less than six hours a night are at higher risk of type 2 diabetes.

    So what can we make of these findings? It turns out the relationship between sleep and diabetes is complex.

    The study

    Researchers analysed data from the UK Biobank, a large biomedical database which serves as a global resource for health and medical research. They looked at information from 247,867 adults, following their health outcomes for more than a decade.

    The researchers wanted to understand the associations between sleep duration and type 2 diabetes, and whether a healthy diet reduced the effects of short sleep on diabetes risk.

    As part of their involvement in the UK Biobank, participants had been asked roughly how much sleep they get in 24 hours. Seven to eight hours was the average and considered normal sleep. Short sleep duration was broken up into three categories: mild (six hours), moderate (five hours) and extreme (three to four hours). The researchers analysed sleep data alongside information about people’s diets.

    Some 3.2% of participants were diagnosed with type 2 diabetes during the follow-up period. Although healthy eating habits were associated with a lower overall risk of diabetes, when people ate healthily but slept less than six hours a day, their risk of type 2 diabetes increased compared to people in the normal sleep category.

    The researchers found sleep duration of five hours was linked with a 16% higher risk of developing type 2 diabetes, while the risk for people who slept three to four hours was 41% higher, compared to people who slept seven to eight hours.

    One limitation is the study defined a healthy diet based on the number of servings of fruit, vegetables, red meat and fish a person consumed over a day or a week. In doing so, it didn’t consider how dietary patterns such as time-restricted eating or the Mediterranean diet may modify the risk of diabetes among those who slept less.

    Also, information on participants’ sleep quantity and diet was only captured at recruitment and may have changed over the course of the study. The authors acknowledge these limitations.

    Why might short sleep increase diabetes risk?

    In people with type 2 diabetes, the body becomes resistant to the effects of a hormone called insulin, and slowly loses the capacity to produce enough of it in the pancreas. Insulin is important because it regulates glucose (sugar) in our blood that comes from the food we eat by helping move it to cells throughout the body.

    We don’t know the precise reasons why people who sleep less may be at higher risk of type 2 diabetes. But previous research has shown sleep-deprived people often have increased inflammatory markers and free fatty acids in their blood, which impair insulin sensitivity, leading to insulin resistance. This means the body struggles to use insulin properly to regulate blood glucose levels, and therefore increases the risk of type 2 diabetes.

    Further, people who don’t sleep enough, as well as people who sleep in irregular patterns (such as shift workers), experience disruptions to their body’s natural rhythm, known as the circadian rhythm.

    This can interfere with the release of hormones like cortisol, glucagon and growth hormones. These hormones are released through the day to meet the body’s changing energy needs, and normally keep blood glucose levels nicely balanced. If they’re compromised, this may reduce the body’s ability to handle glucose as the day progresses.

    These factors, and others, may contribute to the increased risk of type 2 diabetes seen among people sleeping less than six hours.

    While this study primarily focused on people who sleep eight hours or less, it’s possible longer sleepers may also face an increased risk of type 2 diabetes.

    Research has previously shown a U-shaped correlation between sleep duration and type 2 diabetes risk. A review of multiple studies found getting between seven to eight hours of sleep daily was associated with the lowest risk. When people got less than seven hours sleep, or more than eight hours, the risk began to increase.

    The reason sleeping longer is associated with increased risk of type 2 diabetes may be linked to weight gain, which is also correlated with longer sleep. Likewise, people who don’t sleep enough are more likely to be overweight or obese.

    Good sleep, healthy diet

    Getting enough sleep is an important part of a healthy lifestyle and may reduce the risk of type 2 diabetes.

    Based on this study and other evidence, it seems that when it comes to diabetes risk, seven to eight hours of sleep may be the sweet spot. However, other factors could influence the relationship between sleep duration and diabetes risk, such as individual differences in sleep quality and lifestyle.

    While this study’s findings question whether a healthy diet can mitigate the effects of a lack of sleep on diabetes risk, a wide range of evidence points to the benefits of healthy eating for overall health.

    The authors of the study acknowledge it’s not always possible to get enough sleep, and suggest doing high-intensity interval exercise during the day may offset some of the potential effects of short sleep on diabetes risk.

    In fact, exercise at any intensity can improve blood glucose levels.

  • What To Eat, Take, And Do Before A Workout

    What to eat, take, and do before a workout

    We’ve previously written about how to recover quickly after a workout:

    Overdone It? How To Speed Up Recovery After Exercise

    Today we’ll look at the flipside: how to prepare for exercise.

    Pre-workout nutrition

    As per what we wrote (and referenced) above, a good dictum is “protein whenever; carbs after”. See also:

    Pre- versus post-exercise protein intake has similar effects on muscular adaptations

    It’s recommended to have a light, balanced meal a few hours before exercising, though there are nuances:

    International society of sports nutrition position stand: nutrient timing

    Hydration

    You will not perform well unless you are well-hydrated:

    Influence of Dehydration on Intermittent Sprint Performance

    However, you also don’t want to just be sloshing around when exercising because you took care to get in your two litres before hitting the gym.

    For this reason, quality can be more important than quantity, and sodium and other electrolytes can be important and useful, but will not be so for everyone in all circumstances.

    Here’s what we wrote previously about that:

    Are Electrolyte Supplements Worth It?

    Pre-workout supplements

    We previously wrote about the use of creatine specifically:

    Creatine: Very Different For Young & Old People

    Caffeine is also a surprisingly effective pre-workout supplement:

    International society of sports nutrition position stand: caffeine and exercise performance

    Depending on the rate at which you metabolize caffeine (there are genes for this), the effects will come/go earlier/later, but as a general rule of thumb, caffeine should work within about 20 minutes, and will peak in effect 1–2 hours after consumption:

    Nutrition Supplements to Stimulate Lipolysis: A Review in Relation to Endurance Exercise Capacity

    Branched Chain Amino Acids, or BCAAs, are commonly enjoyed as pre-workout supplement to help reduce creatine kinase and muscle soreness, but won’t accelerate recovery:

    …but will help boost muscle-growth (or maintenance, depending on your exercise and diet) in the long run:

    Where can I get those?

    We don’t sell them, but here’s an example product on Amazon, for your convenience 

    There are also many multi-nutrient pre-workout supplements on the market (like the secondary product offered with the BCAA above). We’d need a lot more room to go into all of those (maybe we’ll include some in our Monday Research Review editions), but meanwhile, here’s some further reading:

  • California Becomes Latest State To Try Capping Health Care Spending

    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.

    California’s Office of Health Care Affordability faces a herculean task in its plan to slow runaway health care spending.

    The goal of the agency, established in 2022, is to make care more affordable and accessible while improving health outcomes, especially for the most disadvantaged state residents. That will require a sustained wrestling match with a sprawling, often dysfunctional health system and powerful industry players who have lots of experience fighting one another and the state.

    Can the new agency get insurers, hospitals, and medical groups to collaborate on containing costs even as they jockey for position in the state’s $405 billion health care economy? Can the system be transformed so that financial rewards are tied more to providing quality care than to charging, often exorbitantly, for a seemingly limitless number of services and procedures?

    The jury is out, and it could be for many years.

    California is the ninth state — after Connecticut, Delaware, Massachusetts, Nevada, New Jersey, Oregon, Rhode Island, and Washington — to set annual health spending targets.

    Massachusetts, which started annual spending targets in 2013, was the first state to do so. It’s the only one old enough to have a substantial pre-pandemic track record, and its results are mixed: The annual health spending increases were below the target in three of the first five years and dropped beneath the national average. But more recently, health spending has greatly increased.

    In 2022, growth in health care expenditures exceeded Massachusetts’ target by a wide margin. The Health Policy Commission, the state agency established to oversee the spending control efforts, warned that “there are many alarming trends which, if unaddressed, will result in a health care system that is unaffordable.”

    Neighboring Rhode Island, despite a preexisting policy of limiting hospital price increases, exceeded its overall health care spending growth target in 2019, the year it took effect. In 2020 and 2021, spending was largely skewed by the pandemic. In 2022, the spending increase came in at half the state’s target rate. Connecticut and Delaware, by contrast, both overshot their 2022 targets.

    It’s all a work in progress, and California’s agency will, to some extent, be playing it by ear in the face of state policies and demographic realities that require more spending on health care.

    And it will inevitably face pushback from the industry as it confronts unreasonably high prices, unnecessary medical treatments, overuse of high-cost care, administrative waste, and the inflationary concentration of a growing number of hospitals in a small number of hands.

    “If you’re telling an industry we need to slow down spending growth, you’re telling them we need to slow down your revenue growth,” says Michael Bailit, president of Bailit Health, a Massachusetts-based consulting group, who has consulted for various states, including California. “And maybe that’s going to be heard as ‘we have to restrain your margins.’ These are very difficult conversations.”

    Some of California’s most significant health care sectors have voiced disagreement with the fledgling affordability agency, even as they avoid overtly opposing its goals.

    In April, when the affordability office was considering an annual per capita spending growth target of 3%, the California Hospital Association sent it a letter saying hospitals “stand ready to work with” the agency. But the proposed number was far too low, the association argued, because it failed to account for California’s aging population, new investments in Medi-Cal, and other cost pressures.

    The hospital group suggested a spending increase target averaging 5.3% over five years, 2025-29. That’s slightly higher than the 5.2% average annual increase in per capita health spending over the five years from 2015 to 2020.

    Five days after the hospital association sent its letter, the affordability board approved a slightly less aggressive target that starts at 3.5% in 2025 and drops to 3% by 2029. Carmela Coyle, the association’s chief executive, said in a statement that the board’s decision still failed to account for an aging population, the growing need for mental health and addiction treatment, and a labor shortage.

    The California Medical Association, which represents the state’s doctors, expressed similar concerns. The new phased-in target, it said, was “less unreasonable” than the original plan, but the group would “continue to advocate against an artificially low spending target that will have real-life negative impacts on patient access and quality of care.”

    But let’s give the state some credit here. The mission on which it is embarking is very ambitious, and it’s hard to argue with the motivation behind it: to interject some financial reason and provide relief for millions of Californians who forgo needed medical care or nix other important household expenses to afford it.

    Sushmita Morris, a 38-year-old Pasadena resident, was shocked by a bill she received for an outpatient procedure last July at the University of Southern California’s Keck Hospital, following a miscarriage. The procedure lasted all of 30 minutes, Morris says, and when she received a bill from the doctor for slightly over $700, she paid it. But then a bill from the hospital arrived, totaling nearly $9,000, and her share was over $4,600.

    Morris called the Keck billing office multiple times asking for an itemization of the charges but got nowhere. “I got a robotic answer, ‘You have a high-deductible plan,’” she says. “But I should still receive a bill within reason for what was done.” She has refused to pay that bill and expects to hear soon from a collection agency.

    The road to more affordable health care will be long and chock-full of big challenges and unforeseen events that could alter the landscape and require considerable flexibility.

    Some flexibility is built in. For one thing, the state cap on spending increases may not apply to health care institutions, industry segments, or geographic regions that can show their circumstances justify higher spending — for example, older, sicker patients or sharp increases in the cost of labor.

    For those that exceed the limit without such justification, the first step will be a performance improvement plan. If that doesn’t work, at some point — yet to be determined — the affordability office can levy financial penalties up to the full amount by which an organization exceeds the target. But that is unlikely to happen until at least 2030, given the time lag of data collection, followed by conversations with those who exceed the target, and potential improvement plans.

    In California, officials, consumer advocates, and health care experts say engagement among all the players, informed by robust and institution-specific data on cost trends, will yield greater transparency and, ultimately, accountability.

    Richard Kronick, a public health professor at the University of California-San Diego and a member of the affordability board, notes there is scant public data about cost trends at specific health care institutions. However, “we will know that in the future,” he says, “and I think that knowing it and having that information in the public will put some pressure on those organizations.”

    As you might know, those hairs are really important for our health, so let’s start by mentioning that yes, trimming is the way, not plucking!

    In an ideal world, we’d not trim them further back than the entrance to our nostrils, but given the constant nature of hair-growing, that could become a Sisyphean task.

    A good compromise, if you’re not up for trimming when you get up and having visible hairs by evening, is to put the scissors away (if you haven’t already) and use a nasal hair trimmer; these are good at a) trimming nasal hairs b) abstaining from trimming them too far back.

  • How to Use Topical Estrogen Cream For Aging Skin

    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. Sam Ellis, dermatologist, explains:

    Tackling the cause

    Estrogen is important for very many aspects of health beyond the sexual aspects. When it comes to skin, a drop in estrogen (usually because of menopause) leads to changes like collagen loss, dryness, reduced elasticity, and slower wound healing. Applying estrogen creams to the skin can reverse these changes.

    If your estrogen levels are already within normal pre-menopausal female ranges, by the way, there isn’t so much science to indicate its benefit when used topically. If you are already on systemic HRT (i.e., you take estrogen already to raise your blood estrogen levels and affect your body in its entirety), you may or may not gain extra benefits from the topical cream, depending on factors such as your estrogen dose, your route of administration, your cardiovascular health, and other factors.

    For those with lower estrogen and not currently on HRT, you may be wondering: can topical estrogen cream affect systemic estrogen levels? And the answer is that it mostly depends on the dose. In other words: it’s definitely possible, but for most people it’s unlikely.

    As ever, if thinking of taking up any hormonal treatment, do consult an endocrinologist and/or gynecologist, and if you have an increased breast cancer risk (for example genetically or prior history), then an oncologist too, just to be safe.

    That sounds like a lot of scary things, but mostly it’s just to be on the safe side. The dose of estrogen is very low in topical creams, and even then, only a tiny amount is used per day.

  • Guinness Is Good For You*

    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.

    Guinness Is Good For You*

    *This is our myth-buster edition, so maybe best not take that at face value!

    To this day, writing the words “Guinness is” into Google will autocomplete to “Guinness is good for you”. The ad campaign proclaiming such launched about a hundred years ago, and was based on Guinness as it was when it was launched another hundred years before that.

    Needless to say, none of this was based on modern science.

    Is there any grain of truth?

    Perhaps its strongest health claim, in terms of what stands up to modern scrutiny, is that it does contain some B vitamins. Famously (as it was once given to pregnant women in Ireland on the strength of such) it contains folate (also known as Vitamin B9). How much?

    A 15oz glass of Guinness contains 12.8µg of folate, which is 3.2% of the RDA. In other words, you could get all the folate your body needs by drinking just 32 glasses of Guinness per day.

    With that in mind, you might want to get the non-alcoholic version!

    “I heard you could live on just Guinness and oranges, because it contains everything but vitamin C?”

    The real question is: how long could you live? Otherwise, a facetious answer here could be akin to the “fun fact” that you can drink lava… once.

    Guinness is missing many essential amino acids and fatty acids, several vitamins, and many minerals. Exactly what it’s missing may vary slightly from region to region, as while the broad recipe is the same, some processes add or remove some extra micronutrients.

    As to what you’d die of first, for obvious reasons there have been no studies done on this, but our money would be on liver failure.

    It would also wreak absolute havoc with your kidneys, but kidneys are tricky beasts—you can be down to 10% functionality and unaware that anything’s wrong yet. So we think liver failure would get you first.

    (Need that 0.0% alcohol Guinness link again? Here it is)

    Fun fact: Top contender in the category of “whole food” is actually seaweed (make sure you don’t get too much iodine, though)!

    Or, should we say, top natural contender. Because foods that have been designed by humans to contain everything we need and more for optimized health, such as Huel, do exactly what they say on the tin.

    And in case you’re curious…
