Live, Fast, Live Long
This is Dr. Valter Longo. He’s a biogerontologist and cell biologist, whose work has focused on fasting and nutrient response genes, and how we can leverage them against diseases and aging in general.
We reviewed his book recently:
What does he want us to know?
What to eat
Dr. Longo recommends a mostly plant-based diet (especially vegetables, whole grains, and legumes), but also having some fish. The bulk of our dietary fats, however, he says are best coming from olive oil and nuts.
He also advises aiming for nutritional density of vitamins and minerals in our diet, and/but supplementing with a multivitamin once every few days to cover any gaps.
If in doubt choosing between plant-based whole foods, he recommends that we choose those our ancestors will have eaten.

When to eat
Dr. Longo recommends time-restricted eating within a 12-hour window per day.

However, he also recommends (additionally or separately; it’s up to us; additionally is better but the point is it still has excellent benefits separately too) his “fast-mimicking diet” (FMD), which involves eating according to what we said in “What to eat”, but restricting it to 750 kcal per day, 5 days in a row, but not necessarily 5 days per week.
For example, the following was a 3-month study that involved doing this for only one 5-day cycle per month:
❝Three FMD cycles reduced body weight, trunk, and total body fat; lowered blood pressure; and decreased insulin-like growth factor 1 (IGF-1). No serious adverse effects were reported.
A post hoc analysis of subjects from both FMD arms showed that body mass index, blood pressure, fasting glucose, IGF-1, triglycerides, total and low-density lipoprotein cholesterol, and C-reactive protein were more beneficially affected in participants at risk for disease than in subjects who were not at risk.
Thus, cycles of a 5-day FMD are safe, feasible, and effective in reducing markers/risk factors for aging and age-related diseases.❞

From Strength to Strength – by Dr. Arthur Brooks
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
For most professions, there are ways in which performance can be measured, and the average professional peak varies by profession, but averages are usually somewhere in the 30–45 range, with a pressure to peak between 25–35.
With a peak by age 45 or perhaps 50 at the latest (aside from some statistical outliers, of course), what then to expect at age 50+? Not long after that, there’s a reason for mandatory retirement ages in some professions.
Dr. Brooks examines the case for accepting that rather than fighting it, and/but making our weaknesses into our strengths as we go. If our fluid intelligence slows, our accumulated crystal intelligence (some might call it “wisdom“) can make up for it, for example.
But he also champions the idea of looking outside of ourselves; of the importance of growing and fostering connections; giving to those around us and receiving support in turn; not transactionally, but just as a matter of mutualism of the kind found in many other species besides our own. Indeed, Dr. Brooks gives the example of a grove of aspen trees (hence the cover art of this book) that do exactly that.
The style is very accessible in terms of language but with frequent scientific references, so very much a “best of both worlds” in terms of readability and information-density.
Bottom line: if ever you’ve wondered at what age you might outlive your usefulness, this book will do as the subtitle suggests, and help you carve out your new place.

Minimize Aging’s Metabolic Slump

It’s Q&A Day at 10almonds!
Have a question or a request? We love to hear from you!
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
❝I know that metabolism slows with age, are there any waypoints or things to look out for? I don’t know whether I should be eating less, or doing less, or taking some other approach entirely. What’s recommended?❞
Age and sex count for a lot with this one! As metabolism is in large part directed by hormones:
- For men, declining testosterone (often from around 45 onwards) can result in a metabolic slump
- For women, declining estrogen with the menopause does have an effect, but progesterone is the bigger factor for metabolism in the sense you are talking about.
In both cases, simply taking more of those hormones can often help, but please of course speak with an endocrinologist if that seems like a possible option for you, as your circumstances (and physiology) may vary.
If you’d like to go to that conversation well-armed with information, here are some good starting points, by the way:
- The Testosterone Drop, & Topping Up Testosterone
- Menopausal HRT: Bioidentical vs Animal (It Makes A Difference!)
And if you’re wondering about the natural vs pharmaceutical approaches…
- What Does “Balance Your Hormones” Even Mean?
- What You Should Have Been Told About The Menopause Beforehand
About your metabolic base rate
We tend to think of “fast metabolism good, slow metabolism bad”, and that’s a reasonable general premise… but it’s not necessarily always so.
After all, if you could double your metabolism and keep it there all the time, without changing anything else, well… You’ve heard the phrase “burning the candle at both ends”? So, having at least some downtime is important too.
See for example: Sleep Deprivation & Diabetes Risk
What’s critical, when it comes to base metabolic rate, is that your body must be capable of adequately processing what you are putting into it. Because if your body can’t keep up with the input, it’ll just start storing the excess chemical energy in the quickest and easiest way possible.
…which is a fast track to metabolic disorder in general and type 2 diabetes in particular. For more on the science and mechanics of this, see:
How To Prevent And Reverse Type 2 Diabetes
As for portion sizes…
Your body knows what you need, so listen to it. There is no external source of knowledge that can tell you how much food you need better than your own body itself can tell you.
You may be wondering “how exactly do I listen to my body, though?”, in which case, check out:
The Kitchen Doctor: Interoception & Mindful Eating
As for exercise…
When you exercise, your metabolic rate temporarily increases. After most kinds of exercise, your metabolism slumps again afterwards to compensate.
There are two ways to avoid this:
- Exercise Less, Move More ← it’s about maximizing time spent not sitting still
- High Intensity Interval Training ← a special kind of exercise, the only one known to keep the metabolism running high for a couple of hours afterwards, with no counter-slump
…which makes it pretty effective indeed

Navigating the health-care system is not easy, but you’re not alone.
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.
Hello, dear reader!
This is my first column for Healthy Debate as a Patient Navigator. This column will be devoted to providing patients with information to help them through their journey with the health-care system and answering your questions.
Here’s a bit about me: I have been a patient partner at The Ottawa Hospital and Ottawa Hospital Research Institute since 2017, and have joined a variety of governance boards that work on patient and caregiver engagement such as the Patient Advisors Network, the Ontario Health East Region Patient and Family Advisory Council and the Equity in Health Systems Lab.
My journey as a patient partner started much before 2017 though. When I was a teenager, I was diagnosed with a cholesteatoma, a rare and chronic disease that causes the development of fatty tumors in the middle ear. I have had multiple surgeries to try to fix it but will need regular follow-ups to monitor whether the tumor returns. Because of this, I also live with an invisible disability since I have essentially become functionally deaf in one ear and often rely on a hearing aid when I navigate the world.
Having undergone three surgeries in my adolescent years, it was my experience undergoing surgery for an acute hand and wrist injury following a jet ski accident as an adult that was the catalyst for my decision to become a patient partner. There was an intriguing contrast between how I was cared for at two different health-care institutions, my age being the deciding factor at which hospital I went to (a children’s hospital or an adult one).
The most memorable example was how, as a teenager or child, you were never left alone before surgery, and nurses and staff took all the time necessary to comfort me and answer my (and my family’s) questions. I also remember how right before putting me to sleep, the whole staff initiated a surgical pause and introduced themselves and explained to me what their role was during my surgery.
None of that happened as an adult. I was left in a hallway while the operating theater was prepared, anxious and alone with staff walking by not even batting an eye. My questions felt like an annoyance to the care team; as soon as I was wheeled onto the operating room table, the anesthetist quickly put me to sleep. I didn’t even have the time to see who else was there.
Now don’t get me wrong: I am incredibly appreciative with the quality of care I received, but it was the everyday interactions with the care teams that I felt could be improved. And so, while I was recovering from that surgery, I looked for a way to help other patients and the hospital improve its care. I discovered the hospital’s patient engagement program, applied, and the rest is history!
Since then, I have worked on a host of patient-centered policy and research projects and fervently advocate that surgical teams adopt a more compassionate approach with patients before and after surgery.
I’d be happy to talk a bit more about my journey if you ask, but with that out of the way … Welcome to our first patient navigator column about patient engagement.
Conceptualizing the continuum of Patient Engagement
In the context of Canadian health care, patient engagement is a multifaceted concept that involves active collaboration between patients, caregivers, health-care providers and researchers. It involves patients and caregivers as active contributors in decision-making processes, health-care services and medical research. Though the concept is not new, the paradigm shift toward patient engagement in Canada started around 2010.
I like to conceptualize the different levels of patient engagement as a measure of the strength of the relationship between patients and their interlocutors – whether it’s a healthcare provider, administrator or researcher – charted against the duration of the engagement or the scope of input required from the patient.
Defining different levels of Patient Engagement
Following the continuum, let’s begin by defining different levels of patient engagement. Bear in mind that these definitions can vary from one organization to another but are useful in generally labelling the level of patient engagement a project has achieved (or wishes to achieve).
Patient involvement: If the strength of the relationship between patients and their interlocutors is minimal and not time consuming or too onerous, then perhaps it can be categorized as patient involvement. This applies to many instances of transactional engagement.
Patient advisory/consulting: Right in the middle of our continuum, patients can find themselves engaging in patient advisory or consulting work, where projects are limited in scope and duration or complexity, and the relationship is not as profound as a partnership.
Patient partnership: The stronger the relationship is between the patient and their interlocutor, and the longer the engagement activity lasts or how much input the patient is providing, the more this situation can be categorized as patient partnership. It is the inverse of patient involvement.
Examples of the different levels of Patient Engagement
Let’s pretend you are accompanying a loved one to an appointment to manage a kidney disease, requiring them to undergo dialysis treatment. We’ll use this scenario to exemplify what label could be used to describe the level of engagement.
Patient involvement: In our case, if your loved one – or you – fills out a satisfaction or feedback survey about your experience in the waiting room and all that needed to be done was to hand it back to the clerk or care team, then, at a basic level, you could likely label this interaction as a form of patient involvement. It can also involve open consultations around a design of a new look and feel for a hospital, or the understandability of a survey or communications product. Interactions with the care team, administrators or researchers are minimal and often transactional.
Patient advisory/consulting: If your loved one was asked for more detailed information about survey results over the course of a few meetings, this could represent patient advisory/consulting. This could mean that patients meet with program administrators and care providers and share their insights on how things can be improved. It essentially involves patients providing advice to health-care institutions from the perspective of patients, their family members and caregivers.
Patient advisors or consultants are often appointed by hospitals or academic institutions to offer insights at multiple stages of health-care delivery and research. They can help pilot an initiative based on that feedback or evaluate whether the new solutions are working. Often patient advisors are engaged in smaller-term individual projects and meet with the project team as regularly as required.
Patient partnership: Going above and beyond patient advisory, if patients have built a trusting relationship with their care team or administrators, they could feel comfortable enough to partner with them and initiate a project of their own. This could be for a project in which they study a different form of treatment to improve patient-centered outcomes (like the time it takes to feel “normal” following a session); it could be working together to identify and remove barriers for other patients that need to access that type of care. These projects are not fulfilled overnight, but require a collaborative, longstanding and trusting relationship between patients and health-care providers, administrators or researchers. It ensures that patients, regardless of severity or chronicity of their illness, can meaningfully contribute their experiences to aid in improving patient care, or develop or implement policies, pilots or research projects from start to finish.
It is leveraging that lived and living experience to its full extent and having the patient partner involved as an equal voice in the decision-making process for a project – over many months, usually – that the engagement could be labeled a partnership.
Last words
The point of this column will be to answer or explore issues or questions related to patient engagement, health communications or even provide some thoughts on how to handle a particular situation.
I would be happy to collect your questions and feedback at any time, which will help inform future columns. Just email me at max@le-co.ca or connect with me on social media (Linked In, X / Twitter).
It’s not easy to navigate our health-care systems, but you are not alone.

What Size Breakfast Is Best, By Science?
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.
“Breakfast is the most important meal of the day”, the popular wisdom goes. But, what should it consist of, and how much should we be eating for breakfast?
It has been previously established that it is good if breakfast is the largest meal of the day:
…with meals getting progressively smaller thereafter.
Of course, very many people do the inverse: small (or skipped) breakfast, moderate lunch, larger dinner. This, however, is probably more a result of when eating fits around the modern industrialized workday (and thus gets normalized), rather than actual health considerations.
So, what’s the latest science?
A plucky band of researchers led by Dr. Karla-Alejandra Pérez-Vega investigated the importance of breakfast in the context of heart health. This research was done as part of a larger study into the effects of the Mediterranean Diet on cardiovascular health, so if anyone wants a quick recap before we carry on, then:
The Mediterranean Diet: What Is It Good For? ← the answer, by the way, is “pretty much everything”
…and there are also different versions that each use the Mediterranean Diet as the core, while focussing extra on a different area of health, including one to make it extra heart-healthy:
Four Ways To Upgrade The Mediterranean ← most anti-inflammatory / gut-healthiest / heart-healthiest / brain-healthiest
What they found
In their sample population (n=383) of Spanish adults aged 55–75 with pre-diagnosed metabolic syndrome who, as part of the intervention of this 36-month interventional study, had now for the past 36 months been on a Mediterranean diet but without specific guidance on portion sizes:
- Participants with insufficient breakfast energy intake had the highest adiposity (which is a measure of body fat expressed as a percentage of total mass)
- Participants with low or high (but not moderate) breakfast energy intake had the larger BMI and waist circumference over time
- Participants with low or high (but not moderate) breakfast energy intake had higher triglyceride and lower HDL (good) cholesterol levels
- Participants who consumed 20–30% of their daily calories at breakfast enjoyed the greatest improvements in lipid profiles, with lower triglycerides and higher HDL (good) cholesterol levels
- Participants with lower breakfast quality (lower adherence to Mediterranean Diet) had higher blood pressure levels
- Participants with lower breakfast quality (lower adherence to Mediterranean Diet) had higher blood sugar levels
- Participants with lower breakfast quality (lower adherence to Mediterranean Diet) had lower estimated glomerular filtration rate (which is an indicator of kidney function)
- Participants with higher breakfast quality (higher adherence to Mediterranean Diet) had lower waist circumference, higher HDL cholesterol, and better kidney function
You can see the paper itself here in the Journal of Nutrition, Health, and Aging:
What this means
According to this research, the heart-healthiest breakfast is:
- not skipped
- Mediterranean Diet adherent
- within the range of of 20–30% of the total calories for the day

Resistance band Training – by James Atkinson
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
For those who’d like a full gym workout at home, without splashing out thousands on a home gym, resistance bands provide a lot of value. But how much value, really?
As James Atkinson demonstrates, there’s more exercise available than one might think.
Did you know that you can use the same band to strengthen your triceps as well as your biceps, for instance? and the same goes for your quadriceps and biceps femoris. And core strength? You bet.
The style here is not a sales pitch (though he does, at the end, offer extra resources if desired), but rather, instructional, and this book is in and of itself already a complete guide. With clear instructions and equally clear illustrations, you don’t need to spend a dime more (unless you don’t own a resistance band, in which case then yes, you will need one of those).
Bottom line: if you’d like to give your body the workout it deserves, this book is a potent resource.

How To Clean Your Brain (Glymphatic Health Primer)
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.
That’s not a typo! The name “glymphatic system” was coined by the Danish neuroscientist Dr. Maiken Nedergaard, and is a nod to its use of glial cells to do a similar job to that of the peripheral lymphatic system—but this time, in the CNS. Today, we have Dr. Jin Sung to tell us more:
Brainwashing (but not like that)
The glymphatic system may sound like a boring job, but so does “sanitation worker” in a city—yet the city would grind to a messy halt very very quickly without them. Same goes for your brain.
Diseases that are prevalent when this doesn’t happen the way it should include Alzheimer’s (beta-amyloid clearance) and Parkinson’s (alpha-synuclein clearance) amongst others.
Things Dr. Sung recommends for optimal glymphatic function include: sleep (7–9 hours), exercise (30–45 minutes daily), hydration (half your bodyweight in pounds, in ounces, so if your body weighs 150 lbs, that means 75 oz of water), good posture (including the use of good ergonomics, e.g. computer monitor at right height, car seat correct, etc), stress reduction (reduces inflammatory cytokines), getting enough omega-3 (the brain needs certain fats to work properly, and this is the one most likely to see a deficit), vagal stimulation (methods include humming, gargling, and gagging—please note we said vagal stimulation; easy to misread at a glance!), LED light therapy, and fasting (intermittent or prolonged).
