Some Surprising Truths About Hunger And Satiety
This is Dr. Barbara Rolls. She’s Professor and Guthrie Chair in Nutritional Sciences, and Director of the Laboratory for the Study of Human Ingestive Behavior at Pennsylvania State University, after graduating herself from Oxford and Cambridge (yes, both). Her “awards and honors” take up four A4 pages, so we won’t list them all here.
Most importantly, she’s an expert on hunger, satiety, and eating behavior in general.
What does she want us to know?
First and foremost: you cannot starve yourself thin, unless you literally starve yourself to death.
What this is about: any weight lost due to malnutrition (“not eating enough” is malnutrition) will always go back on once food becomes available. So unless you die first (not a great health plan), merely restricting good will always result in “yo-yo dieting”.
So, to avoid putting the weight back on and feeling miserable every day along the way… You need to eat as much as you feel you need.
But, there’s a trick here (it’s about making you genuinely feel you need less)!
Your body is an instrument—so play it
Your body is the tool you use to accomplish pretty much anything you do. It is, in large part, at your command. Then there are other parts you can’t control directly.
Dr. Rolls advises taking advantage of the fact that much of your body is a mindless machine that will simply follow instructions given.
That includes instructions like “feel hungry” or “feel full”. But how to choose those?
Volume matters
An important part of our satiety signalling is based on a physical sensation of fullness. This, by the way, is why bariatric surgery (making a stomach a small fraction of the size it was before) works. It’s not that people can’t eat more (the stomach is stretchy and can also be filled repeatedly), it’s that they don’t want to eat more because the pressure sensors around the stomach feel full, and signal the hormone leptin to tell the brain we’re full now.
Now consider:
- On the one hand, 20 grapes, fresh and bursting with flavor
- On the other hand, 20 raisins (so, dried grapes), containing the same calories
Which do you think will get the leptin flowing sooner? Of course, the fresh grapes, because of the volume.
So if you’ve ever seen those photos that show two foods side by side with the same number of calories but one is much larger (say, a small slice of pizza or a big salad), it’s not quite the cheap trick that it might have appeared.
Or rather… It is a cheap trick; it’s just a cheap trick that works because your stomach is quite a simple organ.
So, Dr. Rolls’ advice: generally speaking, go for voluminous food. Fruit is great from this, because there’s so much water. Air-popped popcorn also works great. Vegetables, too.
Water matters, but differently than you might think
A well-known trick is to drink water before and with a meal. That’s good, it’s good to be hydrated. However, it can be better. Dr. Rolls did an experiment:
The design:
❝Subjects received 1 of 3 isoenergetic (1128 kJ) preloads 17 min before lunch on 3 d and no preload on 1 d.
The preloads consisted of 1) chicken rice casserole, 2) chicken rice casserole served with a glass of water (356 g), and 3) chicken rice soup.
The soup contained the same ingredients (type and amount) as the casserole that was served with water.❞
The results:
❝Decreasing the energy density of and increasing the volume of the preload by adding water to it significantly increased fullness and reduced hunger and subsequent energy intake at lunch.
The equivalent amount of water served as a beverage with a food did not affect satiety.❞
The conclusion:
❝Consuming foods with a high water content more effectively reduced subsequent energy intake than did drinking water with food.❞
You can read the study in full (it’s a worthwhile read!) here:
Water incorporated into a food but not served with a food decreases energy intake in lean women
Protein matters
With all those fruits and vegetables and water, you may be wondering Dr. Rolls’ stance on proteins. It’s simple: protein is an appetite suppressant.
However, it takes about 20 minutes to signal the brain about that, so having some protein in a starter (if like this writer, you’re the cook of the household, a great option is to enjoy a small portion of nuts while cooking!) gets that clock ticking, to signal satiety sooner.
It may also help in other ways:
Clinical Evidence and Mechanisms of High-Protein Diet-Induced Weight Loss
As for other foods that can suppress appetite, by the way, you might like;

Variety matters, and in ways other than you might think
A wide variety of foods (especially: a wide variety of plants) in one’s diet is well recognized as a key to a good balanced diet.
However…
A wide variety of dishes at the table, meanwhile, promotes greater consumption of food.
Dr. Rolls did a study on this too, a while ago now (you’ll see how old it is) but the science seems robust:
Variety in a Meal Enhances Food Intake in Man
Notwithstanding the title, it wasnot about a man (that was just how scientists wrote in ye ancient times of 1981). The test subjects were, in order: rats, cats, a mixed group of men and women, the same group again, and then a different group of all women.
So, Dr. Rolls’ advice is: it’s better to have one 20-ingredient dish, than 10 dishes with 20 ingredients between them.
Sorry! We love tapas and buffets too, but that’s the science!
So, “one-pot” meals are king in this regard; even if you serve it with one side (reasonable), that’s still only two dishes, which is pretty good going.
Note that the most delicious many-ingredient stir-fries and similar dishes from around the world also fall into this category!

Mythbusting The Big O

“Early To Bed…”
In yesterday’s newsletter, we asked you for your (health-related) views on orgasms.
But what does the science say?
Orgasms are essential to good health: True or False?
False, in the most literal sense. One certainly won’t die without them. Anorgasmia (the inability to orgasm) is a condition that affects many postmenopausal women, some younger women, and some men. And importantly, it isn’t fatal—just generally considered unfortunate:
Anorgasmia Might Explain Why You’re Not Orgasming When You Want To
That article focuses on women; here’s a paper focusing on men:
Orgasms are good for the health, but marginally: True or False?
True! They have a wide array of benefits, depending on various factors (including, of course, one’s own sex). That said, the benefits are so marginal that we don’t have a flock of studies to cite, and are reduced to pop-science sources that verbally cite studies that are, alas, nowhere to be found, for example:
- For women: 9 Orgasm Benefits That Might Surprise You
- For men: 9 Ways Orgasms May Benefit Your Health
Doubtlessly the studies do exist, but are sparse enough that finding them is a nightmare as the keywords for them will bring up a lot of studies about orgasms and health that aren’t answering the above question (usually: health’s affect on orgasms, rather than the other way around).
There is some good science for post-menopausal women, though! Here it is:
Misconceptions About Sexual Health in Older Women
(if you have the time to read this, this also covers many very avoidable things that can disrupt sexual function, in ways that people will errantly chalk up to old age, not knowing that they are missing out needlessly)
Orgasms are good or bad, depending on being male or female: True or False
False, broadly. The health benefits are extant and marginal for almost everyone, as indicated above.
What’s that “almost” about, then?
There are a very few* people (usually men) for whom it doesn’t go well. In such cases, they have a chronic and lifelong problem whereby orgasm is followed by 2–7 days of flu-like and allergic symptoms. Little is known about it, but it appears to be some sort of autoimmune disorder.
Read more: Post-orgasmic illness syndrome: history and current perspectives
*It’s hard to say for sure how few though, as it is surely under-reported and thus under-diagnosed; likely even misdiagnosed if the patient doesn’t realize that orgasms are the trigger for such episodes, and the doctor doesn’t think to ask. Instead, they will be busy trying to eliminate foods from the diet, things like that, while missing this cause.
Orgasms are better avoided for optimal health: True or False?
Aside from the above, False. There is a common myth for men of health benefits of “semen retention”, but it is not based in science, just tradition. You can read a little about it here:
The short version is: do it if you want; don’t if you don’t; the body will compensate either way so it won’t make a meaningful difference to anything for most people, healthwise.
Small counterpoint: while withholding orgasm (and ejaculation) is not harmful to health, what does physiologically need draining sometimes is prostate fluid. But that can also be achieved mechanically through prostate milking, or left to fend for itself (as it will in nocturnal emissions, popularly called wet dreams). However, if you have problems with an enlarged prostate, it may not be a bad idea to take matters into your own hands, so to speak. As ever, do check with your doctor if you have (or think you may have) a condition that might affect this.
One final word…
We’re done with mythbusting for today, but we wanted to share this study that we came across (so to speak) while researching, as it’s very interesting:
On which note: if you haven’t already, consider getting a “magic wand” style vibe; you can thank us later (this writer’s opinion: everyone should have one!).
Top tip: do get the kind that plugs into the wall, not rechargeable. The plug-into-the-wall kind are more powerful, and last much longer (both “in the moment”, and in terms of how long the device itself lasts).
Enjoy!

How To Unfatty A Fatty Liver

How To Unfatty A Fatty Liver
In Greek mythology, Prometheus suffered the punishment of being chained to a rock, where he would have his liver eaten by an eagle, whereupon each day his liver would grow back, only to be eaten again the next day.
We mere humans who are not Greek gods might not be able to endure quite such punishment to our liver, but it is an incredibly resilient and self-regenerative organ.
In fact, provided at least 51% of the liver is still present and correct, the other 49% will regrow. Similarly, damage done (such as by trying to store too much fat there due to metabolic problems, as in alcoholic or non-alcoholic fatty liver disease) will reverse itself in time, given the chance.
The difference between us and Prometheus
In the myth, Prometheus had his liver regrow overnight every night. Ours don’t recover quite so quickly.
Indeed, the science has good and bad news for us:
❝Liver recolonization models have demonstrated that hepatocytes have an unlimited regenerative capacity. However, in normal liver, cell turnover is very slow.❞
~ Michalopoulos and Bhusan (2020)
Read more: Liver regeneration: biological and pathological mechanisms and implications
If it regenerates, why do people need transplants, and/or die of liver disease?
There are some diseases of the liver that inhibit its regenerative abilities, or (as in the case of cancer) abuse them to our detriment. However, in the case of fatty liver disease, the reason is usually simple:
If the lifestyle factors that caused the liver to become fatty are still there, then its regenerative abilities won’t be able to keep up with the damage that is still being done.
Can we speed it up at all?
Yes! The first and most important thing is to minimize how much ongoing harm you are still doing to it, though.
- If you drink alcohol, stop. According to the WHO, the only amount of alcohol that is safe for you is zero.
- You might like our previous article: How To Reduce Or Quit Alcohol
- Consider your medications, and find out which place a strain on the liver. Many medications are not optional; you’re taking them for an important reason, so don’t quit things without checking with your doctor. Medications that strain the liver include, but are by no means limited to:
- Many painkillers, including acetaminophen/paracetamol (e.g. Tylenol), and ibuprofen
- Some immunosuppresent drugs, including azathioprine
- Some epilepsy drugs, including phenytoin
- Some antibiotics, including amoxicillin
- Statins in general
Note: we are not pharmacists, nor doctors, let alone your doctors.
Check with yours about what is important for you to take, and what alternatives might be safe for you to consider.
Dietary considerations
While there are still things we don’t know about the cause(s) of non-alcoholic fatty liver disease, there is a very strong association with a diet that is:
- high in salt
- high in refined carbohydrates
- e.g. white flour and white flour products such as white bread and white pasta; also the other main refined carbohydrate: sugar
- high in red meat
- high in non-fermented dairy
- high in fried foods.
So, consider minimizing those, and instead getting plenty of fiber, and plenty of lean protein (not from red meat, but poultry and fish are fine iff not fried; beans and legumes are top-tier, though).
Also, hydrate. Most people are dehydrated most of the time, and that’s bad for all parts of the body, and the liver is no exception. It can’t regenerate if it’s running on empty!

How long will it take to heal?
In the case of alcoholic fatty liver disease, it should start healing a few days after stopping drinking. Then, how long it takes to fully recover depends on the extent of the damage; it could be weeks or months. In extreme cases, years, but that is rare. Usually if the damage is that severe, a transplant is needed.
In the case of non-alcoholic fatty liver disease, again it depends on the extent of the damage, but it is usually a quicker recovery than the alcoholic kind—especially if eating a Mediterranean diet.

Feminist narratives are being hijacked to market medical tests not backed by evidence
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.
Corporations have used feminist language to promote their products for decades. In the 1980s, companies co-opted messaging about female autonomy to encourage women’s consumption of unhealthy commodities, such as tobacco and alcohol.
Today, feminist narratives around empowerment and women’s rights are being co-opted to market interventions that are not backed by evidence across many areas of women’s health. This includes by commercial companies, industry, mass media and well-intentioned advocacy groups.
Some of these health technologies, tests and treatments are useful in certain situations and can be very beneficial to some women.
However, promoting them to a large group of asymptomatic healthy women that are unlikely to benefit, or without being transparent about the limitations, runs the risk of causing more harm than good. This includes inappropriate medicalisation, overdiagnosis and overtreatment.
In our analysis published today in the BMJ, we examine this phenomenon in two current examples: the anti-mullerian hormone (AMH) test and breast density notification.
The AMH test
The AMH test is a blood test associated with the number of eggs in a woman’s ovaries and is sometimes referred to as the “egg timer” test.
Although often used in fertility treatment, the AMH test cannot reliably predict the likelihood of pregnancy, timing to pregnancy or specific age of menopause. The American College of Obstetricians and Gynaecologists therefore strongly discourages testing for women not seeking fertility treatment.
The AMH test can’t predict your chance of getting pregnant.
Anastasia Vityukova/UnsplashDespite this, several fertility clinics and online companies market the AMH test to women not even trying to get pregnant. Some use feminist rhetoric promising empowerment, selling the test as a way to gain personalised insights into your fertility. For example, “you deserve to know your reproductive potential”, “be proactive about your fertility” and “knowing your numbers will empower you to make the best decisions when family planning”.
The use of feminist marketing makes these companies appear socially progressive and champions of female health. But they are selling a test that has no proven benefit outside of IVF and cannot inform women about their current or future fertility.
Our recent study found around 30% of women having an AMH test in Australia may be having it for these reasons.
Misleading women to believe that the test can reliably predict fertility can create a false sense of security about delaying pregnancy. It can also create unnecessary anxiety, pressure to freeze eggs, conceive earlier than desired, or start fertility treatment when it may not be needed.
While some companies mention the test’s limitations if you read on, they are glossed over and contradicted by the calls to be proactive and messages of empowerment.
Breast density notification
Breast density is one of several independent risk factors for breast cancer. It’s also harder to see cancer on a mammogram image of breasts with high amounts of dense tissue than breasts with a greater proportion of fatty tissue.
While estimates vary, approximately 25–50% of women in the breast screening population have dense breasts.
Dense breasts can make it harder to detect cancer.
Tyler Olsen/ShutterstockStemming from valid concerns about the increased risk of cancer, advocacy efforts have used feminist language around women’s right to know such as “women need to know the truth” and “women can handle the truth” to argue for widespread breast density notification.
However, this simplistic messaging overlooks that this is a complex issue and that more data is still needed on whether the benefits of notifying and providing additional screening or tests to women with dense breasts outweigh the harms.
Additional tests (ultrasound or MRI) are now being recommended for women with dense breasts as they have the ability to detect more cancer. Yet, there is no or little mention of the lack of robust evidence showing that it prevents breast cancer deaths. These extra tests also have out-of-pocket costs and high rates of false-positive results.
Large international advocacy groups are also sponsored by companies that will financially benefit from women being notified.
While stronger patient autonomy is vital, campaigning for breast density notification without stating the limitations or unclear evidence of benefit may go against the empowerment being sought.
Ensuring feminism isn’t hijacked
Increased awareness and advocacy in women’s health are key to overcoming sex inequalities in health care.
But we need to ensure the goals of feminist health advocacy aren’t undermined through commercially driven use of feminist language pushing care that isn’t based on evidence. This includes more transparency about the risks and uncertainties of health technologies, tests and treatments and greater scrutiny of conflicts of interests.
Health professionals and governments must also ensure that easily understood, balanced information based on high quality scientific evidence is available. This will enable women to make more informed decisions about their health.

Getting Things Done – by David Allen
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 “to-do” lists are usually hopelessly tangled:
“To do thing x needs thing y doing first but that can only be done with information that I must get by doing thing z”, and so on.
Suddenly that two-minute task is looking like half an hour, which is making our overall to-do list look gargantuan. Tackling tiny parts of tasks seems useless; tackling large tasks seems overwhelming. What a headache!
Getting Things Done (“GTD”, to its friends) shows us how to gather all our to-dos, and then use the quickest ways to break down a task (in reality, often a mini-project) into its constituent parts and which things can be done next, and what order to do them in (or defer, or delegate, or ditch).
In a nutshell: The GTD system aims to make all your tasks comprehensible and manageable, for stress-free productivity. No need to strategize everything every time; you have a system now, and always know where to begin.
And by popular accounts, it delivers—many put this book in the “life-changing” category.

Cows’ Milk, Bird Flu, & 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.
When it comes to dairy products, generally speaking, fermented ones (such as most cheeses and yogurts) are considered healthy in moderation, and unfermented ones have their pros and cons that can be argued and quibbled “until the cows come home”. We gave a broad overview, here:
Furthermore, you may recall that there’s some controversy/dissent about when human babies can have cows’ milk:
When can my baby drink cow’s milk? It’s sooner than you think
So, what about bird flu now?
Earlier this year, the information from the dairy industry was that it was nothing to be worried about for the time being:
Bird Flu Is Bad for Poultry and Dairy Cows. It’s Not a Dire Threat for Most of Us — Yet.
More recently, the latest science has found:
❝We found a first-order decay rate constant of −2.05 day–1 equivalent to a T99 of 2.3 days. Viral RNA remained detectable for at least 57 days with no degradation. Pasteurization (63 °C for 30 min) reduced infectious virus to undetectable levels and reduced viral RNA concentrations, but reduction was less than 1 log10.
The prolonged persistence of viral RNA in both raw and pasteurized milk has implications for food safety assessments and environmental surveillance❞
You can find the study here:
Infectivity and Persistence of Influenza A Virus in Raw Milk
In short: raw milk keeps the infectious virus; pasteurization appears to render it uninfectious, though viral RNA remains present.
This is relevant, because of the bird flu virus being found in milk:
World Health Organization | H5N1 strain of bird flu found in milk
To this end, a moratorium has been placed on the sale of raw milk, first by the California Dept of Public Health (following an outbreak in California):
California halts sales of raw milk due to bird flu virus contamination
And then, functionally, by the USDA, though rather than an outright ban, it’s requiring testing for the virus:
USDA orders testing of milk supply for presence of bird flu virus
So, is pasteurized milk safe?
The official answer to this, per the FDA, is… Honestly, a lot of hand-wringing and shrugging. What we do know is:
- the bird flu virus has been found in pasteurized milk too
- the test for this is very sensitive, and has the extra strength/weakness that viral fragments will flag it as a positive
- it is assumed that the virus was inactivated by the pasteurization process
- it could, however, have been the entire virus, the test simply does not tell us which
In the FDA’s own words:
❝The pasteurization process has served public health well for more than 100 years. Even if the virus is detected in raw milk, pasteurization is generally expected to eliminate pathogens to a level that does not pose a risk to consumer health❞
So, there we have it: the FDA does not have a reassurance exactly, but it does have a general expectation.

Move – by Caroline Williams
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.
- Get 150 minutes of moderate exercise per week, says the American Heart Association
- There are over 10,000 minutes per week, says the pocket calculator
Is 150/10,000 really the goal here? Really?
For Caroline Williams, the answer is no.
In this book that’s practically a manifesto, she outlines the case that:
- Humans evolved to move
- Industrialization and capitalism scuppered that
- We now spend far too long each day without movement
Furthermore, for Williams this isn’t just an anthropological observation, it’s a problem to be solved, because:
- Our lack of movement is crippling us—literally
- Our stagnation affects not just our bodies, but also our minds
- (again literally—there’s a direct correlation with mental health)
- We urgently need to fix this
So, what now, do we need to move in to the gym and become full-time athletes to clock up enough hours of movement? No.
Williams convincingly argues the case (using data from supercentenarian “blue zones” around the world) that even non-exertive movement is sufficient. In other words, you don’t have to be running; walking is great. You don’t have to be lifting weights; doing the housework or gardening will suffice.
From that foundational axiom, she calls on us to find ways to build our life around movement… rather than production-efficiency and/or convenience. She gives plenty of tips for such too!
Bottom line: some books are “I couldn’t put it down!” books. This one’s more of a “I got the urge to get up and get moving!” book.
