How Does Fat Actually Leave The Body? Where Does It Go?

Fat loss is often misunderstood, with many believing it simply “vanishes” through exercise, is simply excreted in solid form in the bathroom, or materially disappears when converted for energy. However, the principle of conservation of mass plays out here, in that the mass in fat doesn’t disappear—it changes its arrangement:
In and out
Fat is composed of carbon, hydrogen, and oxygen atoms, with an example common form of fat in the body being C55H104O6. That’s a lot of Cs and Hs, and a few Os.
When fat leaves the body, it has been primarily converted into carbon dioxide (CO2) and water (H2O).
According to a 2014 study by the University of South Wales, 84% of the mass of fat exits the body as CO2 exhaled through breathing, while 16% leaves as water through sweat, urine, and other bodily fluids (all of which contain H2O).
You’ll notice there are a lot more Os going out, proportionally, than we originally had in the C55H104O6. For this reason, the process requires oxygen intake; for every 10 kilograms of fat burned, by simple mathematics the body needs around 29 kilograms of oxygen.
Physical activity plays a crucial role in fat loss. When the body exerts itself, it naturally switches to a higher oxygen metabolism necessary for fat breakdown. This effect is amplified during intermittent fasting, which boosts human growth hormone (HGH), a hormone that aids in fat metabolism.
However, simply hyperventilating won’t work; exercise is essential to activate these processes—otherwise it’s just a case of oxygen in, oxygen out, without involving the body’s chemical energy reserves.
Consequently, one of the best diet-and-exercise combinations for fat loss is intermittent fasting with high-intensity interval training.
And, as for what to eat, this video says raw vegan, but honestly, that’s not scientific consensus. However, a diet rich in unprocessed (or minimally processed) fruits and vegetables definitely is where it’s at, with the plant-heavy Mediterranean diet generally scoring highest—which can be further improved by skipping the mammals to make it pesco-Mediterranean. Current scientific consensus does not give any extra benefits for also omitting moderate consumption of fish and fermented dairy products, so include those if you want, or skip those if you prefer.

The 4 Bad Habits That Cause The Most Falls While Walking
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.
The risk of falling becomes greater (both in probability and in severity of consequences) as we get older. But, many people who do fall do so for the same reasons, some of which are avoidable. Dr. Doug Weiss has advice based on extensive second-hand experience:
Best foot forward!
If any of these prompt a “surely nobody does that” response, then, good for you to not have that habit, but Dr. Weiss has seen many patients who thusly erred. And if any of these do describe how you walk, then well, you’re not alone—time to fix it, though!
- Walking with Stiff Legs: walking with a hyperextended (straight) knee instead of a slight bend (5-15°) makes it harder to adjust balance, increasing the risk of falls. This can also put extra pressure on the joints, potentially leading to osteoarthritis.
- Crossing Legs While Turning: turning by crossing one leg over the other is a common cause of falls, particularly in the elderly. To avoid this, when turning step first with the foot that is on the side you are going to go. If you have the bad habit, this may feel strange at first, but you will soon adapt.
- Looking Down While Walking: focusing only on the ground directly in front of you can cause you to miss obstacles ahead, leading to falls. Instead, practice “scanning”, alternating between looking down at the ground and looking up to maintain awareness of your surroundings.
- Shuffling Instead of Tandem Walking: shuffling with feet far apart, rather than walking with one foot in front of the other, reduces balance and increases the risk of tripping. Tandem walking, where one foot is placed directly in front of the other, is the safer and more balanced way to walk.
It also helps disguise your numbers.

21% Stronger Bones in a Year at 62? Yes, It’s Possible (No Calcium Supplements Needed!)
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.
Bone density is a concern for a lot of people past a certain age, and it can lead to an endless juggling of vitamin and mineral supplements to try to get the right balance. Sachiaki Takamiya advocates for a natural diet- and exercise-based approach instead, showing good results with his Okinawan-influenced Blue Zones diet and lifestyle.
As a caveat, he has not gone through menopause, so this video does completely overlook the implications of that. Nevertheless, even if some of us must get our hormones from a bottle these days, this diet and exercise approach is a very good foundation and the advice here is important for all—we can take all the estrogen we need and still have weak bones if our diet and exercise aren’t there as needed.
From strength to strength
Sachiaki Takamiya’s bone density wasn’t bad the previous year, but this year it is better, hitting 123.4%. This is important information, because it’s easier to achieve an n% increase (for any given value of n) if your starting point is lower. For example, a 50% increase from 1g is 1.5g (so, 0.5g difference), whereas a 50% increase from 20g is 30g (so, a 10g difference). Since his starting value was high, this makes his 21% rise particularly noteworthy—and mean that a reader with a lower starting value will most likely see even better gains, if implementing this protocol.
You may be wondering: isn’t a bone mass density of 123.4% about 23.4% more than we want it? And the answer is that the 100% value is taken from an average peak bone mass in young adults, so having it at 100% is fine, and having it a bit higher is still better—it just means he’s outclassing healthy young adults, less likely to break a bone if he falls, etc.
As for what he ate: he focused on getting calcium and magnesium, as well as vitamins D and K2, all from food sources. Key foods included small fish (sardines, niosi, jaco), nattō, mushrooms, and seaweed (nori, wakame, hijiki). In particular, he emphasizes nattō’s benefits for bones, as well as for the gut, heart, and brain.
As for his exercise: he did weight-bearing exercise and resistance training—including calisthenics and yoga, as well as sport, and simply walking and running. His weekly routine looked like this:
- Monday: heart rate zone 2 jogging (45 min)
- Tuesday: bodyweight HIIT and flexibility (20 min)
- Wednesday: heart rate zone 2 jogging (60 min)
- Thursday: bodyweight HIIT and flexibility (40 min)
- Friday: heart rate zone 2 jogging (45 min)
- Saturday: bodyweight HIIT and flexibility (20 min)
…as well as social sports (e.g. tennis, amongst others), and additional activities such as gardening, and cycling for groceries.

What Teas To Drink Before Bed (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.
Which Sleepy Tea?
Herbal “tea” preparations (henceforth we will write it without the quotation marks, although these are not true teas) are popular for winding down at the end of a long day ready for a relaxing sleep.
Today we’ll look at the science for them! We’ll be brief for each, because we’ve selected five and have only so much room, but here goes:
Camomile
Simply put, it works and has plenty of good science for it. Here’s just one example:
❝Noteworthy, our meta-analysis showed a significant improvement in sleep quality after chamomile administration❞
Also this writer’s favourite relaxation drink!
(example on Amazon if you want some)
Lavender
We didn’t find robust science for its popularly-claimed sedative properties, but it does appear to be anxiolytic, and anxiety gets in the way of sleep, so while lavender may not be a sedative, it may calm a racing mind all the same, thus facilitating better sleep:
(example on Amazon if you want some)
Magnolia
Animal study for the mechanism:
Human study for “it is observed to help humans sleep better”:
As you can see from the title, its sedative properties weren’t the point of the study, but if you click through to read it, you can see that they found (and recorded) this benefit anyway
(example on Amazon if you want some)
Passionflower
There’s not a lot of evidence for this one, but there is some. Here’s a small study (n=41) that found:
❝Of six sleep-diary measures analysed, sleep quality showed a significantly better rating for passionflower compared with placebo (t(40) = 2.70, p < 0.01). These initial findings suggest that the consumption of a low dose of Passiflora incarnata, in the form of tea, yields short-term subjective sleep benefits for healthy adults with mild fluctuations in sleep quality.❞
So, that’s not exactly a huge body of evidence, but it is promising.
(example on Amazon if you want some)
Valerian
We’ll be honest, the science for this one is sloppy. It’s very rare to find Valerian tested by itself (or sold by itself; we had to dig a bit to find one for the Amazon link below), and that skews the results of science and renders any conclusions questionable.
And the studies that were done? Dubious methods, and inconclusive results:
Nevertheless, if you want to try it for yourself, you can do a case study (i.e., n=1 sample) if not a randomized controlled trial, and let us know how it goes 🙂
(example on Amazon if you want some)
Summary
- Valerian we really don’t have the science to say anything about it
- Passionflower has some nascent science for it, but not much
- Lavender is probably not soporific, but it is anxiolytic
- Magnolia almost certainly helps, but isn’t nearly so well-backed as…
- Camomile comes out on top, easily—by both sheer weight of evidence, and by clear conclusive uncontroversial results.
Enjoy!

Oranges vs Lemons – Which is Healthier?
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 Verdict
When comparing oranges to lemons, we picked the oranges.
Why?
In the battle of these popular citrus fruits, there is a clear winner on the nutritional front.
Things were initially promising for lemons when looking at the macros—lemons have a little more fiber while oranges are slightly higher in carbs, but the differences are small and both are very healthy in this regard.
However, alas for this writer who prefers sour fruits to sweet ones (I’m sweet enough already), the micronutrient profiles tell a different story:
In terms of vitamins, oranges have more of vitamins A, B1, B2, B3, B5, B9, E, and choline. In contrast, lemons have a (very) little more vitamin B6. You might be wondering about vitamin C, since both fruits are famous for that—they’re equal on vitamin C. But, with that stack we listed above, oranges clearly win the vitamin category easily.
As for minerals, oranges boast more calcium, copper, magnesium, potassium, selenium, and zinc, while lemons have more iron, manganese, and phosphorus.
Technically lemons also have more sodium, but the numbers are truly miniscule (by coincidence, we discover upon grabbing a calculator, you’d need to eat approximately your own bodyweight in whole lemons to get to the RDA of sodium—and that’s to reach the RDA, not the upper healthy limit) so we’ll overlook the tiny sodium difference as irrelevant. Which means, while closer than the vitamins category, oranges win on minerals with a 6:3 lead over lemons.
Both fruits offer generous helpings of flavonoids and other polyphenols such as naringenin and hesperidin, which have anti-inflammatory properties and more specifically can also reduce allergy symptoms (unless, of course, you are allergic to citrus fruits, which is a relatively rare but extant allergy).
In short: as ever, enjoy both; diversity is great for the health. But if you want to maximize the nutrients you get, it’s oranges.

Mindsight – by Dr. Daniel Siegel
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.
A lot of books these days bear the subtitle “The New Science Of…”, but usually it’s not new, and often it’s not even science. So how does this one measure up?
- Is it new? The core ideas are mostly very old, but some of the interventions are new in presentation—and backed by relatively recent research—so we can give him this one on a technicality at least
- It is science? Yes! The author is a clinician (a psychatric clinician, specifically) and there’s nothing here that doesn’t have its foundations in robust science.
So, what’s this “mindsight”, then? Dr. Siegel wants to express to us a concept “for which no word currently exists”, so he had to make one up, to convey the idea of having a conscious awareness of what is going on in our brain, on an experiential basis. In other words: “mindfulness”. There was totally already a word for this, which he goes on to lampshade not very far into the book.
Nevertheless, we’ll forgive him a little copywriting swizzle with the title, because the content here is genuinely top-tier.
In the book, many ideas from many other pop-psychology books are covered, in useful, practical, no-nonsense fashion, laying out tools and interventions to strengthen various parts of our brain and our relationship with same.
Bottom line: this is the most comprehensive, science-centric, book on mindfulness that this reviewer has read.

The Science of Nutrition – by Rhiannon Lambert
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.
While there are a lot of conflicting dietary approaches out there, the science itself is actually fairly cohesive in most regards. This book does a lot of what we do here at 10almonds, and presents the science in a clear fashion without having any particular agenda to push.
The author is a nutritionist (BSc, MSc, RNutr) and therefore provides an up-to-date evidence-based approach for eating.
As a result, the only part of this book that brings it down in this reviewer’s opinion is the section on Intermittent Fasting. Being not strictly about nutrition, she has less expertise on that topic, and it shows.
The information is largely presented in double-page spreads each answering a particular question. Because of this, and the fact there are colorful graphic representations of information too, we do recommend the print version over Kindle*.
Bottom line: if you like the notion of real science being presented in a clear and simple fashion (we like to think our subscribers do!), then you’ll surely enjoy this book.
Click here to check out the Science of Nutrition, and get a clear overview!
*Writer’s note: I realize I’ve two days in a row recommended this (yesterday because there are checkboxes to check, worksheets to complete, etc), but it’s not a new trend; just how it happened to be with these two books. I love my Kindle dearly, but sometimes print has the edge for one reason or another!
