Glucomannan For Weight Loss, Gut Health, & More

Glucomannan is a water-soluble dietary fiber found in the root of the konjac plant.
If you’ve had konjac noodles, also called shirataki, that’s what those are mostly made of, and it’s why they have next-to-no calories.
You may be wondering: if it’s water-soluble, how do the noodles not dissolve in water? And the answer is that the noodle-making process involves making a gel out of the fiber and water, which is then extruded into noodle shapes. In this gelatinous form, they’re fairly stable (it’s one of the most viscous dietary fibers), but yes, if you were to boil them for a long time, they would indeed turn the entire liquid contents of the saucepan into gel.
How it works for weight loss
Because of its viscosity, adding even a small amount of powdered* glucomannan to a glass of water will turn the whole thing into gel in seconds. This means that if you take glucomannan capsules with a glass of water, then so far as your stomach is concerned, you just ate a cup of gel, and the water is now processed as food, staying longer in the stomach than it otherwise would, and promoting feelings of fullness.
*i.e. dry powder, not in a gelatinous form like the noodles
As for its efficacy in weight loss, see for example:
❝Glucomannan was well-tolerated and resulted in significant weight loss in overweight and obese individuals❞
Read more: Glucomannan and obesity: a critical review
So, that covers the basic requirements, but may be wondering: does it have other benefits? And the answer is yes, it does:
❝Glucomannan appears to beneficially affect total cholesterol, LDL cholesterol, triglycerides, body weight, and fasting blood glucose❞
To further corroborate that and comment on safety…
❝Results showed a significant mean weight loss using glucomannan over an eight-week period. Serum cholesterol and low-density lipoprotein cholesterol were significantly reduced in the glucomannan treated group. No adverse reactions to glucomannan were reported.❞

As to whether other gel-making agents work the same way, the answer is no, they don’t seem to:
❝Glucomannan induced body weight reduction in healthy overweight subjects, whereas the addition of guar gum and alginate did not seem to cause additional loss of weight❞

How it works for gut health
In the words of Dr. Yu Li et al.,
❝Konjaku flour can achieve positive effects on treating obesity, which manifest on reducing BMI, fat mass, blood glucose, and blood lipid, improving hepatic function, and also regulating intestinal microfloral structure.
Therefore, changes in gut microbiota may explain in part the effects of konjaku flour.❞

This has extra positive knock-on effects too:

We Are Such Stuff As Fish Are Made Of

Research Review: Collagen
For something that’s a very popular supplement, not many people understand what collagen is, where it comes from, or what it does.
In a nutshell:
Collagen is a kind of protein. Our bodies make it naturally, and we can also get more in our diet and/or take extra as a supplement.
Our bodies use collagen in connective tissue, skin, tendon, bone, and cartilage. It has many functions, but a broad description would be “holding things together”.
As we get older, our bodies produce less collagen. Signs of this include wrinkles, loss of skin hydration, and joint pain.
Quick test: pinch the skin on the middle of the back of one of your hands, and then watch what happens when you get low. How quickly and easily did your skin returns to its original shape?
If it was pretty much instantanous and flawless, congratulations, you have plenty of collagen (and also elastin). If you didn’t, you are probably low on both!
(they are quite similar proteins and are made from the same base “stuff”, so if you’re low on one, you’ll usually be low on both)
Quick note: A lot of research out there has been funded by beauty companies, so we had our work cut out for us today, and have highlighted where any research may be biased.
More than skin deep
While marketing for collagen is almost exclusively aimed at “reduce wrinkles and other signs of aging”, it does a lot more than that.
You remember we mentioned that many things from the bones outward are held together by collagen? We weren’t kidding…
Read: Osteoporosis, like skin ageing, is caused by collagen loss which is reversible
Taking extra collagen isn’t the only way
We can’t (yet!) completely halt the age-related loss of collagen, but we can slow it, with our lifestyle choices:
- Don’t smoke tobacco
- Drink only in moderation (or not at all)
- Avoid foods with added sugar, and high-processed foods in general
- Wear sunscreen when appropriate
Can I get collagen from food?
Yep! Just as collagen holds our bodies together, it holds the bodies of other animals together. And, just like collagen is found in most parts of our body but most plentifully in our skin and bones, that’s what to eat to get collagen from other animals, e.g:
- Chicken skin
- Fish skin
- Bone broth ← health benefits and recipes at this link!
What about vegans?
Yes, vegans are also held together by collagen! We do not, however, recommend eating their skin or boiling their bones into broth. Ethical considerations aside, cannibalism can give you CJD!
More seriously, if you’re vegan, you can’t get collagen from a plant-based diet, but you can get the stuff your body uses to make collagen. Basically, you want to make sure you get plenty of:
- Protein (beans, pulses, nuts, etc are all fine; it’s hard to go wrong with this)
- Vitamin C
- Vitamin D
- and Zinc
Just be sure to continue to remember to avoid highly-processed foods. So:
- Soy mince/chunks whose ingredients list reads: “soya”? Yes!
- The Incredible Burger or Linda McCartney’s Sausages? Sadly less healthy
Read: Advanced Glycation End Products in Foods and a Practical Guide to Their Reduction in the Diet
Meat-eaters might want to read that one too. By far the worst offenders for AGEs (Advanced Glycation End Products, which can not only cause collagen to stiffen, but also inactivate proteins responsible for collagen repair, along with doing much more serious damage to your body’s natural functions) include:
- Hot dogs
- Bacon
- Fried/roasted/grilled meats
Is it worth it as a supplement?
That depends on you, your age, and your lifestyle, but it’s generally considered safe*
*if you have a seafood allergy, be careful though, as many supplements are from fish or shellfish—you will need to find one that’s free from your allergen
Also, all collagen is animal-derived. So if you’re a vegan, decide for yourself whether this constitutes medicine and if so, whether that makes it ethically permissible to you.
With that out of the way:
What the science says on collagen supplementation
Collagen for skin
Read: Effects of collagen supplementation on skin aging (systematic review and meta-analysis)
The short version is that they selected 19 studies with over a thousand participants in total, and they found:
In the meta-analysis, a grouped analysis of studies showed favorable results of hydrolyzed collagen supplementation compared with placebo in terms of skin hydration, elasticity, and wrinkles.
The findings of improved hydration and elasticity were also confirmed in the subgroup meta-analysis.
Based on results, ingestion of hydrolyzed collagen for 90 days is effective in reducing skin aging, as it reduces wrinkles and improves skin elasticity and hydration.
Caveat: while that systematic review had no conflicts of interests, at least some of the 19 studies will have been funded by beauty companies. Here are two, so that you know what that looks like:
Funded by Quiris to investigate their own supplement, Elasten®:
A Collagen Supplement Improves Skin Hydration, Elasticity, Roughness, and Density
Funded by BioCell to investigate their own supplement, BioCell Collagen:
The Effects of Skin Aging Associated with the Use of BioCell Collagen
A note on funding bias: to be clear, the issue is not that the researchers might be corrupt (though that could happen).
The issue is more that sometimes companies will hire ten labs to do ten research studies… and then pull funding from ones whose results aren’t going the way they’d like.
So the “best” (for them) study is the one that gets published.
Here’s another systematic review—like the one at the top of this section—that found the same, with doses ranging from 2.5g–15g per day for 8 weeks or longer:
Read: Oral Collagen Supplementation: A Systematic Review of Dermatological Applications
Again, some of those studies will have been funded by beauty companies. The general weight of evidence does seem clear and favorable, though.
Collagen for bones
Here, we encountered a lot less in the way of potential bias, because this is simply marketed a lot less. Despite being arguably far more important!
We found a high quality multi-vector randomized controlled study with a sample size of 131 postmenopausal women. They had these women take 5g collagen supplement (or placebo), and studied the results over the course of a year.
They found:
- The intake of the supplement increased bone mineral density (BMD)
- Supplementation was also associated with a favorable shift in bone markers, indicating:
- increased bone formation
- reduced bone degradation
Read: Specific Collagen Peptides Improve Bone Mineral Density and Bone Markers in Postmenopausal Wome
A follow-up study with 31 of these women found that taking 5 grams of collagen daily for a total of 4 years was associated with a progressive increase in BMD.
You might be wondering if collagen also helps against osteoarthritis.
The answer is: yes, it does (at least, it significantly reduces the symptoms)
Read: Effect of collagen supplementation on osteoarthritis symptoms
In summary:
- You need collagen for health skin, bones, joints, and more
- Your body makes collagen from your food
- You can help it by getting plenty of protein, vitamins, and minerals
- You can also help it by not doing the usual Bad Things™ (smoking, drinking, eating processed foods, especially processed meats)
- You can also eat collagen directly in the form of other animals’ skin and bones
- You can also buy collagen supplements (but watch out for allergens)
Want to try collagen supplementation?
We don’t sell it (or anything else), but for your convenience…
Check it out: Hydrolyzed Collagen Peptides (the same as in most of the above studies), 90 days supply at 5g/day
We selected this one because it’s the same kind used in many of the studies, and it doesn’t contain any known allergens.
It’s bovine collagen, meaning it’s from cows, so it’s not vegan, and also some subscribers may want to abstain for religious reasons. We respect that, and/but make our recommendations based solely on the science of health and productivity.

Is Fast Food Really All That Bad?
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.
Yes, yes it is. However, most people misunderstand the nature of its badness, which is what causes problems. The biggest problem is not the acute effects of one afternoon’s burger and fries; the biggest problem is the gradual slide into regularly eating junk food, and the long-term effects of that habit as our body changes to accommodate it (of which, people tend to focus on subcutaneous fat gain as it’s usually the most visible, but that’s really the least of our problems).
Cumulative effects
There are, of course, immediate negative effects too, and they’re not without cause for concern. Because of the composition of most junk food, it will almost by definition result in immediate blood sugar spikes, rising insulin levels, and a feeling of fatigue not long afterwards.
- Within a week of regularly consuming junk food, gut bacteria will change, resulting in moderate cravings, as well as a tendency towards depression and anxiety. Mood swings are likely, as are the gastrointestinal woes associated with any gut microbiota change.
- Within two weeks, those effects will be greater, the cravings will increase, energy levels will plummet, and likely skin issues may start to show up (our skin mostly works on a 3-week replacement cycle; some things can show up in the skin more quickly or slowly than that, though).
- Within three weeks, the rest of our blood metrics (e.g. beyond blood sugar imbalances) will start to stray from safe zones. Increased LDL, decreased HDL, and the beginnings of higher cardiovascular disease risk and diabetes risk.
- Within a month, we will likely see the onset of non-alcoholic fatty liver disease, and chronic inflammation sets in, raising the risk of a lot of other diseases, especially immune disorders and cancer.
If that seems drastic, along the lines of “eat junk food for a month and get cancer”, well, it’s an elevated risk, not a scheduled diagnosis, but the body is constantly rebuilding itself, for better or for worse, and if we sabotage its efforts by consuming a poor diet, then it will be for worse.
The good news is: this works both ways, and we can get our body back on track in fairly short order too, by enjoying a healthier diet; our body will be thrilled to start repairing itself. And of course, all these effects, good and bad, are proportional to how well or badly we eat. There’s a difference between doing a “Supersize Me” month-long 100% junk food diet, and “merely” getting a junk food breakfast each day and eating healthily later.
In short, if your diet is only moderately bad, then you will only be moderately unwell.

Complex PTSD – by Pete Walker
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.
We’ve written before about Complex PTSD, but there’s a lot more to be said than we can fit into an article or two.
Pete Walker, a licensed marriage and family therapist, does an excellent job and pulls no punches, starting from the book’s dedication and carrying the hard-hitting seriousness all the way through to the Appendices.
To this end, it absolutely may not be an easy book to read at times (emotionally speaking), especially if you have C-PTSD. On the other hand, you may also find it a very validating 300-odd pages of “Yes, he is telling my life story in words, now this makes sense!”
That said, it’s mostly not an anecdotes-based book and nor is it just a feelsy ride; it’s also a textbook and a how-to manual. It’s a textbook of how and why things come about the way they do, and a manual of how to effectively manage C-PTSD, and find peace. There’s no silver bullet here, but there is a very comprehensive guide, and chapters full of tools to use (and no, not the same CBT things you’ve probably read a hundred times, this is C-PTSD-specific stuff).
Bottom line: this is the C-PTSD book; if you buy only one book on the topic, make it this one.

The Couple’s Guide to Thriving with ADHD – by Melissa Orlov and Nancie Kohlenberger
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.
ADHD (what a misleadingly-named condition) is most often undiagnosed in adults, especially older adults, and has far-reaching effects. This book explores those!
Oftentimes ADHD is not a deficit of attention, it’s just a lack of choice about where one’s attention goes. And the H? It’s mostly not what people think it is. The diagnostic criteria have moved far beyond the original name.
But in a marriage, ADHD symptoms such as wandering attention, forgetfulness, impulsiveness, and a focus on the “now” to the point of losing sight of the big picture (the forgotten past and the unplanned future), can cause conflict.
The authors write in a way that is intended for the ADHD and/or non-ADHD partner to read, and ideally, for both to read.
They shine light on why people with or without ADHD tend towards (or away from) certain behaviours, what miscommunications can arise, and how to smooth them over.
Best of all, an integrated plan for getting you both on the same page, so that you can tackle anything that arises, as the diverse team (with quite different individual strengths) that you are.
Bottom line: if you or a loved one has ADHD symptoms, this book can help you navigate and untangle what can otherwise sometimes get a little messy.

The Good Skin Solution – by Shann Jones
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 everyone knows that eczema is not just a skin condition; it’s an autoimmune condition. And thus to heal one’s skin, the gut is a good place to start.
This is not your average gut health book though, because it is focused on optimizing things for one’s skin… Although the author herself learned about this while helping her husband to battle an MRSA infection. In other words, a multi-fronted battle for sure.
The advices in this book are good for, as the subtitle promises, an assortment of other skin conditions too, including psoriasis, rosacea, and acne. She covers the usual bases, and recommends probiotics, of which she’s particularly keen to praise kefir, while advising against the use of antibiotics unless absolutely necessary—something we’ve talked about from time to time at 10almonds, too.
Not content to merely cover those things, she also talks allergies, and walking the fine line between avoiding triggers and developing hypersensitivity by treating to live in a perfectly clean bubble.
Ultimately, she offers “7 daily habits”, 3 of which involve goat’s milk kefir, that’s how keen on it she is. So if you’re vegan, probably this book isn’t as good value, however much it discusses the health woes that can be caused and/or exacerbated by drinking cow’s milk.
The style is very light and personable, which makes for easy reading, more like one friend talking to another, than a scientific textbook.
Bottom line: if you’d like healthier skin, are interested in dietary tweaks and homemade soaps, and have no aversion to goat’s milk and/or kefir, then this book is full of fascinating pointers.

The Good Life – by Robert Waldinger, MD, and Marc Schulz, PhD
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 any who have thought “there must be some middle-ground between entirely subjective self-help books advising how to feel better, and sifting through clinical data on what actually affects people’s moods“, this book is exactly that middle-ground!
Drs. Waldinger and Schultz went through the 80-year-long Harvard Study of Adult Development with a fine-toothed comb, and this book details—more readably—what they found.
There are frequent references to data from the study. Not just numbers, though, people’s answers to questions, too. And how different factors about people’s lives affected their answers to the same questions.
We hear from all ages, from young adults to octagenarians, and learn how attitudes (including: of the same people) change over time. Not because people are fickle, but because people grow… or become disillusioned. Or sometimes, both.
We learn about the importance of money… And where that importance ends.
We learn importance of relationships of various kinds, and this is certainly a recurring theme throughout the study—and thus, throughout the book.
The book doesn’t just present data, though, it also presents actionable insights along the way.
Bottom line: the combined wisdom and life-experiences of a lot of people provide a very “big picture” view of life, and what makes us happy, really. We highly recommend it!
