Intermittent Fasting: What’s the truth?
Before we get to facts and fictions, let’s quickly cover:
What is Intermittent Fasting?
Intermittent Fasting (IF) is an umbrella term for various kinds of time-restricted fasting, based on a schedule. Types include:
Time-restricted IF, for example:
- 16:8—Fast for 16 hours, eat during an 8-hour window
- 18:6–Fast for 18 hours, eat during a 6-hour window
- 20:4—Fast for 20 hours, eat during a 4-hour window
24hr fasting, including:
- Eat Stop Eat—basically, take a day off from eating once a week
- Alternate Day Fasting—a more extreme version of the above; it is what it sounds like; eat one day, fast the next, repeat
Non-fast fasting, e.g:
- 5:2—Eat normally for 5 days, have a very reduced calorie intake (⅓ of normal intake) for the other 2 days
- Fruit Fasting—have a small amount of fruit on “fast” days, but no other food
- The Warrior Diet—as above, but include a small amount of non-starchy vegetables
Why IF?
While IF is perhaps most commonly undertaken as a means of fat loss or fat management (i.e., keeping fat down when it is already low), others cite different reasons, such as short term cognitive performance or long-term longevity.
But… Does it work?
Here we get into the myth-busting bit!
“IF promotes weight loss”
Mix of True and False. It can! But it also doesn’t have to. If you’re a bodybuilder who downs 4,000 calories in your 4hr eating window, you’re probably not going to lose weight! For such people, this is of course “a feature, not a bug” of IF—especially as it has been found that, in an acute study, IF did not adversely impact muscle protein synthesis.
“IF promotes fat loss, without eating less”
Broadly True. IF was found to be potentially equal to, but not necessarily better than, eating less.
“IF provides metabolic benefits for general health”
Broadly True. IF (perhaps counterintuitively) decreases the risk of insulin resistance, and also has anti-inflammatory effects, benefits a healthy gut microbiome, and promotes healthy autophagy (which as we noted in a previous edition of 10almonds, is important against both aging and cancer)
However, results vary according to which protocol you’re observing…
For what it’s worth, 16:8 is perhaps the most-studied protocol. Because such studies tend to have the eating window from midday to 8pm, this means that—going against popular wisdom—part of the advice here is basically “skip breakfast”.
“Unlike caloric restriction, IF is sustainable and healthy as a long-term protocol”
Broadly True. Of course, there’s a slight loophole here in that IF is loosely defined—technically everyone fasts while they’re sleeping, at the very least!
However, for the most commonly-studied IF method (16:8), this is generally very sustainable and healthy and for most people.
On the other hand, a more extreme method such as Alternate Day Fasting, may be trickier to sustain (even if it remains healthy to do so), because it’s been found that hunger does not decrease on fasting days—ie, the body does not “get used to it”.
The American Journal of Clinical Nutrition wrote:
❝Alternate-day fasting was feasible in nonobese subjects, and fat oxidation increased. However, hunger on fasting days did not decrease, perhaps indicating the unlikelihood of continuing this diet for extended periods of time. Adding one small meal on a fasting day may make this approach to dietary restriction more acceptable.❞
“IF improves mood and cognition”
Mix of True and False (plus an honest “We Don’t Know” from researchers).
Many studies have found benefits to both mood and cognition, but in the short-term, fasting can make people “hangry” (or: “experience irritability due to low blood sugar levels”, as the scientists put it), and in the long term, it can worsen symptoms of depression for those who already experience such—although some studies have found it can help alleviate depressive symptoms.
Basically this is one where researchers typically append the words “more research is needed” to their summaries.
“Anyone can do IF”
Definitely False, unless going by the absolute broadest possible interpretation of what constitutes “Intermittent Fasting” to the point of disingenuity.
For example, if you are Type 1 Diabetic, and your blood sugars are hypo, and you wait until tomorrow to correct that, you will stand a good chance of going into a coma instead. So please don’t.
(On the other hand, IF may help achieve remission of type 2 diabetes)
Lastly, IF is broadly not recommend to children and adolescents, anyone pregnant or breastfeeding, and certain underlying health conditions not mentioned above (we’re not going to try to give an exhaustive list here, but basically, if you have a chronic health condition, we recommend you check with your doctor first).

Falling: Is It Due To Age Or Health Issues?
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.
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 😎
❝What are the signs that a senior is falling due to health issues rather than just aging?❞
Superficial answer: having an ear infection can result in a loss of balance, and is not particularly tied to age as a risk factor
More useful answer: first, let’s consider these two true statements:
- The risks of falling (both the probability and the severity of consequences) increase with age
- Health issues (in general) tend to increase with age
With this in mind, it’s difficult to disconnect the two, as neither exist in a vacuum, and each is strongly associated with the other.
So the question is easier to answer by first flipping it, to ask:
❝What are the health issues that typically increase with age, that increase the chances of falling?❞
A non-exhaustive list includes:
- Loss of strength due to sarcopenia (reduced muscle mass)
- Loss of mobility due to increased stiffness (many causes, most of which worsen with age)
- Loss of risk-awareness due to diminished senses (for example, not seeing an obstacle until too late)
- Loss of risk-awareness due to reduced mental focus (cognitive decline producing absent-mindedness)
Note that in the last example there, and to a lesser extent the third one, reminds us that falls also often do not happen in a vacuum. There is (despite how it may sometimes feel!) no actual change in our physical relationship with gravity as we get older; most falls are about falling over things, even if it’s just one’s own feet:
The 4 Bad Habits That Cause The Most Falls While Walking
Disclaimer: sometimes a person may just fall down for no external reason. An example of why this may happen is if a person’s joint (for example an ankle or a knee) has a particular weakness that means it’ll occasionally just buckle and collapse under one’s own weight. This doesn’t even have to be a lot of weight! The weakness could be due to an old injury, or Ehlers-Danlos Syndrome (with its characteristic joint hypermobility symptoms), or something else entirely.
Now, notice how:
- all of these things can happen at any age
- all of these things are more likely to happen the older we get
- none of these things have to happen at any age
That last one’s important to remember! Aging is often viewed as an implacable Behemoth, but the truth is that it is many-faceted and every single one of those facets can be countered, to a greater or lesser degree.
Think of a room full of 80-year-olds, and now imagine that…
- One has the hearing of a 20-year-old
- One has the eyesight of a 20-year-old
- One has the sharp quick mind of a 20-year-old
- One has the cardiovascular fitness of a 20-year-old
…etc. Now, none of those things in isolation is unthinkable, so remember, there is no magic law of the universe saying we can’t have each of them:
Age & Aging: What Can (And Can’t) We Do About It?
Which means: that goes for the things that increase the risk of falling, too. In other words, we can combat sarcopenia with protein and resistance training, maintain our mobility, look after our sensory organs as best we can, nourish our brain and keep it sharp, etc etc etc:
Train For The Event Of Your Life! (Mobility As A Long-Term “Athletic” Goal For Personal Safety)
Which doesn’t mean: that we will necessarily succeed in all areas. Your writer here, broadly in excellent health, and whose lower body is still a veritable powerhouse in athletic terms, has a right ankle and left knee that will sometimes just buckle (yay, the aforementioned hypermobility).
So, it becomes a priority to pre-empt the consequences of that, for example:
- being able to fall with minimal impact (this is a matter of knowing how, and can be learned from “soft” martial arts such as aikido), and
- ensuring the skeleton can take a knock if necessary (keeping a good balance of vitamins, minerals, protein, etc; keeping an eye on bone density).

The Vagus Nerve’s Power for Weight Loss
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. Arun Dhir is a university lecturer, a gastrointestinal surgeon, an author, and a yoga and meditation instructor, and he has this to say:
Gut feelings
The vagus nerve is the 10th cranial nerve, also known as “vagus” (“the wanderer”), because it travels from the brain to many other body parts, including the ears, throat, heart, respiratory system, gut, pancreas, liver, and reproductive system. It’s no surprise then, that it plays a key role in brain-gut communication and metabolism regulation.
The vagus nerve is part of the parasympathetic nervous system, responsible for rest, digestion, and counteracting the stress response. Most signals through the vagus nerve travel from the gut to the brain, though there is communication in both directions.
You may be beginning to see how this works and its implications for weight management: the vagus nerve senses metabolites from the liver, pancreas, and small intestine, and regulates insulin production by stimulating beta cells in the pancreas, which is important for avoiding/managing insulin resistance and metabolic syndrome in general.
Dr. Dhir cites a study in which vagus nerve stimulation (originally used for treating epilepsy and depression) was shown to cause unintentional weight loss (6-11%) in patients, revealing a link to weight management. Of course, that is quite a specific sample, so more research is needed to say for sure, but because the principle is very sound and the mechanism of action is clear, it’s not being viewed as a controversial conclusion.
As for how get these benefits, here are seven ways:
- Cold water on the face: submerge your face in cold water in the morning while holding water in your mouth, or cover your face with a cold wet washcloth (while holding your breath please; no need to waterboard yourself!), which activates the “mammalian dive response” in which your body activates the parasympathetic nervous system in order to remain calm and thus survive for longer underwater
- Alternate hot and cold showers: switch between hot and cold water during showers for 10-second intervals; this creates eustress and activates the process of hormesis, improving your overall stress management and reducing any chronic stress response you may otherwise have going on
- Humming and gargling: the vibrations in the throat stimulate the nearby vagus nerve
- Deep breathing (pranayama): yoga breathing exercises, especially combined with somatic exercises such as the sun salutation, can stimulate the vagus nerve
- Intermittent fasting: helps recalibrate the metabolism and indirectly improves vagus nerve function
- Massage and acupressure: stimulates lymphatic channels and the vagus nerve
- Long walks in nature (“forest bathing”): helps trigger relaxation in general

Loaded Mocha Chocolate Parfait
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.
Packed with nutrients, including a healthy dose of protein and fiber, these parfait pots can be a healthy dessert, snack, or even breakfast!
You will need (for 4 servings)
For the mocha cream:
- ½ cup almond milk
- ½ cup raw cashews
- ⅓ cup espresso
- 2 tbsp maple syrup
- 1 tsp vanilla extract
For the chocolate sauce:
- 4 tbsp coconut oil, melted
- 2 tbsp unsweetened cocoa powder
- 1 tbsp maple syrup
- 1 tsp vanilla extract
For the other layers:
- 1 banana, sliced
- 1 cup granola, no added sugar
Garnish (optional): 3 coffee beans per serving
Note about the maple syrup: since its viscosity is similar to the overall viscosity of the mocha cream and chocolate sauce, you can adjust this per your tastes, without affecting the composition of the dish much besides sweetness (and sugar content). If you don’t like sweetness, the maple syrup be reduced or even omitted entirely (your writer here is known for her enjoyment of very strong bitter flavors and rarely wants anything sweeter than a banana); if you prefer more sweetness than the recipe called for, that’s your choice too.
Method
(we suggest you read everything at least once before doing anything)
1) Blend all the mocha cream ingredients. If you have time, doing this in advance and keeping it in the fridge for a few hours (or even up to a week) will make the flavor richer. But if you don’t have time, that’s fine too.
2) Stir all the chocolate sauce ingredients together in a small bowl, and set it aside. This one should definitely not be refrigerated, or else the coconut oil will solidify and separate itself.
3) Gently swirl the the mocha cream and chocolate sauce together. You want a marble effect, not a full mixing. Omit this step if you want clearer layers.
4) Assemble in dessert glasses, alternating layers of banana, mocha chocolate marble mixture (or the two parts, if you didn’t swirl them together), and granola.
5) Add the coffee-bean garnish, if using, and serve!
Enjoy!

On This Bright Day – by Dr. Susan Thompson
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.
This book is principally aimed at those who have struggled with emotional/comfort eating, over-eating, and/or compulsive eating of some kind.
However, its advices go for the “little compulsions” too, the many small unhealthy choices that add up. Thus, this book has value for most if not all of us.
The format is: each day has a little quotation, followed by a short discussion of that, which is then underlined by an affirmation for the day.
The main thrust of the book is to promote mindful eating, and it does this well with daily reminders that are helpful without being preachy.
Bottom line: if you enjoy “daily reader” type books and would like a daily reminder to practice mindful eating, then this book is for you!
Click here to check out On This Bright Day, and enjoy your food mindfully, every day!

The Oh She Glows Cookbook – by Angela Liddon
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.
Let’s get the criticism out of the way first: notwithstanding the subtitle promising over 100 recipes, there are about 80-odd here, if we discount recipes that are no-brainer things like smoothies, sides such as for example “roasted garlic”, or meta-ingredients such as oat flour (instructions: blend the oats and you get oat flour).
The other criticism is more subjective: if you are like this reviewer, you will want to add more seasonings than recommended to most of the recipes. But that’s easy enough to do.
As for the rest: this is a very healthy cookbook, and quite wide-ranging and versatile, with recipes that are homely, with a lot of emphasis on comfort foods (but still, healthy), though certainly some are perfectly worthy of entertaining too.
A nice bonus of this book is that it offers a lot of available substitutions (much like we do at 10almonds), and also ways of turning the recipe into something else entirely with just a small change. This trait more than makes up for the slight swindle in terms of number of recipes, since some of the recipes have bonus recipes snuck in.
Bottom line: if you’d like to broaden your plant-based cooking range, this book is a fine option for expanding your repertoire.

Lies I Taught in Medical School – by Dr. Robert Lufkin
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.
There seems to be a pattern of doctors who practice medicine one way, get a serious disease personally, and then completely change their practice of medicine afterwards. This is one of those cases.
Dr. Lufkin here presents, on a chapter-by-chapter basis, the titularly promised “lies” or, in more legally compliant speak (as he acknowledges in his preface), flawed hypotheses that are generally taught as truths. In many cases, the “lie” is some manner of “xyz is normal and nothing to worry about”, and/or “there is nothing to be done about xyz; suck it up”.
The end result of the information is not complicated—enjoy a plants-forward whole foods low-carb diet to avoid metabolic diseases and all the other things to branch off from same (Dr. Lufkin makes a fair case for metabolic disease leading to a lot of secondary diseases that aren’t considered metabolic diseases per se). But, the journey there is actually important, as it answers a lot of questions that are much less commonly understood, and often not even especially talked-about, despite their great import and how they may affect health decisions beyond the dietary. Things like understanding the downsides of statins, or the statistical models that can be used to skew studies, per relative risk reduction and so forth.
Bottom line: this book gives the ins and outs of what can go right or wrong with metabolic health and why, and how to make sure you don’t sabotage your health through missing information.
