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❞

Read more: Effect of glucomannan on plasma lipid and glucose concentrations, body weight, and blood pressure: systematic review and meta-analysis

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:

  • Hanging Exercises For Complete Beginners & Older Adults

    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.

    Hanging (not the kind with a gallows) is great for the heath, improving not just strength and mobility, but also—critically—looking after spinal health too. Amanda Raynor explains in this video how this exercise is accessible to anyone (unless you have no arms, in which case, sorry, this one is just not for you—though hanging by your legs will also give similar spinal benefits!).

    Hanging out

    Hanging can be done at home or at a park, with minimal equipment (a bar, a sturdy tree branch, etc).

    Note: the greater the diameter of the bar, the more it will work your grip strength, and/but the harder it will be. So, it’s recommend to start with a narrow-diameter bar first.

    Getting started:

    • Start with a “dead hang”: grip the bar with hands shoulder-width apart, thumb wrapped around.
    • Aim to hang without pulling up; build endurance gradually (10–30 seconds is fine at first).
    • Work up to holding for 60 seconds in three sets as a fitness goal.

    Progression:

    • If unable to hang at all initially, use a chair or stool to support some body weight.
    • Gradually reduce foot support to increase duration of free hanging.
    • Start with 10 seconds, progressing by small increments (e.g: 15, 20, 25 seconds) until reaching 60 seconds.

    Advanced variations:

    • Move the body while hanging (e.g., circles, knee lifts).
    • Experiment with different grips (overhand, underhand) for varied muscle engagement.
    • Try scapular pulls or one-arm hangs for additional challenge and strength-building.

    While these are quite high-calorie, they’re also high in protein, and the fiber and healthy fats flatten the blood sugar curve:

    You will need

    • 1 cup peanut butter
    • 4 oz dark chocolate, melted (try to get dark chocolate with >80% cocoa, if you can; 85% is very respectable and 90% is perfect)
    • ⅓ cup maple syrup (you can safely reduce this, or even omit it, if you prefer less sweetness)
    • ¼ cup hazelnuts
    • ¼ cup almond milk (or your preferred milk, but we recommend almond for taste and health)
    • 1 tsp vanilla extract
    • Topping: ¼ cup hazelnuts, roughly chopped

    Method

    (we suggest you read everything at least once before doing anything)

    1) Combine all the ingredients (except the topping) in a food processor, and blend until smooth.

    2) Line a container (5″x7″ is a good size) with baking paper and spread the mixture evenly into it, pressing down gently.

    3) Sprinkle the topping onto it, press that even more gently into it.

    4) Refrigerate overnight (or chill it for 2hrs in the freezer).

    5) Cut into cubes to serve; they can be served frozen or thawed, per your preference:

  • Stop Cancer 20 Years Ago

    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 Abreast And Keep Abreast

    This is Dr. Jenn Simmons. Her specialization is integrative oncology, as she—then a breast cancer surgeon—got breast cancer, decided the system wasn’t nearly as good from the patients’ side of things as from the doctors’ side, and took to educate herself, and now others, on how things can be better.

    What does she want us to know?

    Start now

    If you have breast cancer, the best time to start adjusting your lifestyle might be 20 years ago, but the second-best time is now. We realize our readers with breast cancer (or a history thereof) probably have indeed started already—all strength to you.

    What this means for those of us without breast cancer (or a history therof) is: start now

    Even if you don’t have a genetic risk factor, even if there’s no history of it in your family, there’s just no reason not to start now.

    Start what, you ask? Taking away its roots. And how?

    Inflammation as the root of cancer

    To oversimplify: cancer occurs because an accidentally immortal cell replicates and replicates and replicates and takes any nearby resources to keep on going. While science doesn’t know all the details of how this happens, it is a factor of genetic mutation (itself a normal process, without which evolution would be impossible), something which in turn is accelerated by damage to the DNA. The damage to the DNA? That occurs (often as not) as a result of cellular oxidation. Cellular oxidation is far from the only genotoxic thing out there, and a lot of non-food “this thing causes cancer” warnings are usually about other kinds of genotoxicity. But cellular oxidation is a big one, and it’s one that we can fight vigorously with our lifestyle.

    Because cellular oxidation and inflammation go hand-in-hand, reducing one tends to reduce the other. That’s why so often you’ll see in our Research Review Monday features, a line that goes something like:

    “and now for those things that usually come together: antioxidant, anti-inflammatory, anticancer, and anti-aging”

    So, fight inflammation now, and have a reduced risk of a lot of other woes later.

    See: How to Prevent (or Reduce) Inflammation

    Don’t settle for “normal”

    People are told, correctly but not always helpfully, such things as:

    • It’s normal to have less energy at your age
    • It’s normal to have a weaker immune system at your age
    • It’s normal to be at a higher risk of diabetes, heart disease, etc

    …and many more. And these things are true! But that doesn’t mean we have to settle for them.

    We can be all the way over on the healthy end of the distribution curve. We can do that!

    (so can everyone else, given sufficient opportunity and resources, because health is not a zero-sum game)

    If we’re going to get a cancer diagnosis, then our 60s are the decade where we’re most likely to get it. Earlier than that and the risk is extant but lower; later than that and technically the risk increases, but we probably got it already in our 60s.

    So, if we be younger than 60, then now’s a good time to prepare to hit the ground running when we get there. And if we missed that chance, then again, the second-best time is now:

    See: Focusing On Health In Our Sixties

    Fast to live

    Of course, anything can happen to anyone at any age (alas), but this is about the benefits of living a fasting lifestyle—that is to say, not just fasting for a 4-week health kick or something, but making it one’s “new normal” and just continuing it for life.

    This doesn’t mean “never eat”, of course, but it does mean “practice intermittent fasting, if you can”—something that Dr. Simmons strongly advocates.

    See: Intermittent Fasting: We Sort The Science From The Hype

    While this calls back to the previous “fight inflammation”, it deserves its own mention here as a very specific way of fighting it.

    It’s never too late

    All of the advices that go before a cancer diagnosis, continue to stand afterwards too. There is no point of “well, I already have cancer, so what’s the harm in…?”

    The harm in it after a diagnosis will be the same as the harm before. When it comes to lifestyle, preventing a cancer and preventing it from spreading are very much the same thing, which is also the same as shrinking it. Basically, if it’s anticancer, it’s anticancer, no matter whether it’s before, during, or after.

    Dr. Simmons has seen too many patients get a diagnosis, and place their lives squarely in the hands of doctors, when doctors can only do so much.

    Instead, Dr. Simmons recommends taking charge of your health as best you are able, today and onwards, no matter what. And that means two things:

    1. Knowing stuff
    2. Doing stuff

    So it becomes our responsibility (and our lifeline) to educate ourselves, and take action accordingly.

    So, no question/request too big or small

    ❝I’d be interested in OTC prostrate medication safety and effectiveness.❞

    Great idea! Sounds like a topic for a main feature one day soon, but while you’re waiting, you might like this previous main feature we did, about a supplement that performs equally to some prescription BPH meds:

    ❝Was very interested in the article on ginko bilboa as i moved into a home that has the tree growing in the backyard. Is there any way i can process the leaves to make a tea out of it.❞

    Glad you enjoyed! First, for any who missed it, here was the article on Ginkgo biloba:

    Ginkgo Biloba, For Memory And, Uh, What Else Again?

    Now, as that article noted, Ginkgo biloba seeds and leaves are poisonous. However, there are differences:

    The seeds, raw or roasted, contain dangerous levels of a variety of toxins, though roasting takes away some toxins and other methods of processing (boiling etc) take away more. However, the general consensus on the seeds is “do not consume; it will poison your liver, poison your kidneys, and possibly give you cancer”:

    Ginkgo biloba L. seed; A comprehensive review of bioactives, toxicants, and processing effects

    The leaves, meanwhile, are much less poisonous with their ginkgolic acids, and their other relevant poison is very closely related to that of poison ivy, involving long-chain alkylphenols that can be broken down by thermolysis, in other words, heat:

    Leaves, seeds and exocarp of Ginkgo biloba L. (Ginkgoaceae): A Comprehensive Review of Traditional Uses, phytochemistry, pharmacology, resource utilization and toxicity

    However, this very thorough examination of the potential health benefits and risks of ginkgo tea, comes to the general conclusion “this is not a good idea, and is especially worrying in elders, and/or if taking various medications”:

    Medicinal Values and Potential Risks Evaluation of Ginkgo biloba Leaf Extract (GBE) Drinks Made from the Leaves in Autumn as Dietary Supplements

    In summary:

    • Be careful
    • Avoid completely if you have a stronger-than-usual reaction to poison ivy
    • If you do make tea from it, green leaves appear to be safer than yellow ones
    • If you do make tea from it, boil and stew to excess to minimize toxins
    • If you do make tea from it, doing a poison test is sensible (i.e. start with checking for a skin reaction to a topical application on the inside of the wrist, then repeat at least 6 hours later on the lips, then at least 6 hours later do a mouth swill, then at least 12 hours later drink a small amount, etc, and gradually build up to “this is safe to consume”)

    For safety (and legal) purposes, let us be absolutely clear that we are not advising you that it is safe to consume a known poisonous plant, and nor are we advising you to do so.

    But the hopefully only-ever theoretical knowledge of how to do a poison test is a good life skill, just in case

  • The Longevity Diet – by Dr. Valter Longo

    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.

    Another book with “The New Science” in its subtitle, so, is this one a new science?

    Yes and no; some findings are new, many are not, what really sets this book apart from many of its genre though is that rather than focusing on fighting aging, it focuses on retaining youth. While this may seem like one and the same thing, there is a substantive difference beyond the ideological, which is: while anti-aging research focuses on what causes people to suffer age-related decline and fights each of those things, Dr. Longo’s research focuses on what is predominant in youthful bodies, cells, DNA, and looks to have more of that. Looking in a slightly different place means finding slightly different things, and knowledge is power indeed.

    Dr. Longo bases his research and focus on his “5 pillars of longevity”. We’ll not keep them a mystery; they are:

    1. Juventology research
    2. Epidemiology
    3. Clinical studies
    4. Centenarian studies
    5. Study of complex systems

    The first there (juventology research) may sound like needless jargon, but it is the counterpoint of the field of gerontology, and is otherwise something that didn’t have an established name.

    You may wonder why “clinical studies” gets a separate item when the others already include studies; this is because many studies when it comes to aging and related topics are population-based studies, cohort studies, observational studies, or (as is often the case) multiple of the above at once.

    Of course, all this discussion of academia is not itself practical information for the reader (unless we happen to work in the field), but it is interesting and does give confidence in the conclusions upon which the practical parts of the book are based.

    And what are they? As the title suggests, it’s about diet, and specifically, it’s about Dr. Longo’s “fast-mimicking diet”, which boasts the benefits of intermittent fasting without intermittent fasting. This hinges, of course, on avoiding metabolic overload, which can be achieved with a fairly simple diet governed by the principles outlined in this book, based on the research referenced.

    In the category of subjective criticism, there is quite a bit of fluff, much of it self-indulgently autobiographical and very complimentary, but its presence does not take anything away from the excellent content contained in the book.

    Bottom line: if you’d like a fresh perspective on regaining/retaining youthfulness, then this is a great book to read.

  • How To Out-Cheat “Cheat Days”

    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.

    Out-Cheating “Cheat Days” (Or Even Just “Cheat Meals”)

    If you are in the habit of eating healthily, the idea of a “cheat day” probably isn’t appealing—because you simply don’t crave junk food; it’s not what your gut is used to.

    Nevertheless, sometimes cheat days, or at least cheat meals, choose us rather than the other way around. If your social group is having a pizza night or meeting up at the burger bar, probably you’re going to be having a meal that’s not ideal.

    So, what to do about it?

    Well, first of all, relax. If it really is an exception and not a regular occurrence, it’s not going to have a big health impact. Assuming that your basic dietary requirements are taken care of (e.g. free from allergens as necessary, vegan/vegetarian if that’s appropriate for you, adhering to any religious restrictions that are important to you, etc), then you’re going to have a good time, which is what scientists call a “pro-social activity” and is not a terrible thing.

    See also: Is Fast Food Really All That Bad? ← answer: yes it is, but the harm is cumulative and won’t all happen the instant you take a bite of a chicken nugget

    Think positive

    No, not in the “think positive thoughts” sense (though feel free, if that’s your thing), but rather: focus on adding things rather than subtracting things.

    It’s said:

    It’s not the calories in your food that make the biggest impact on your health; it’s the food in your calories❞e

    …and that’s generally true. The same goes for “bad things” in the food, e.g. added sugar, salt, seed oils, etc. They really are bad! But, in this case you’re going to be eating them and they’re going to be nearly impossible to avoid in the social scenarios we described. So, forget that sunk treasure, and instead, add nutrients.

    10almonds tip: added nutrients remain added nutrients, even if the sources were not glowing with health-appeal and/or you ate them alongside something unhealthy:

    • Those breaded garlic mushrooms are still full of magnesium and fiber and ergothioneine.
    • The chili-and-mint peas that came as an overpriced optional side-dish with your burger are still full of protein, fiber, and a stack of polyphenols.

    …and so on. And, the more time you spend eating those things, the less time you spend eating the real empty-calorie foods.

    Fix the flaw

    We set out to offer this guide without arguing for abstemiousness or making healthy substitutions, because we assume you knew already that you can not eat things, and as for substitutions, often they are not practical, especially if dining out or ordering in.

    Also, sometimes even when home-cooking something unhealthy, taking the bad ingredient out takes some of the joy out with it.

    Writers example: I once incorrectly tried to solve the fat conundrum of my favorite shchi (recipe here) by trying purely steaming the vegetables instead of my usual frying/sautéing them, and let’s just say, that errant-and-swiftly-abandoned version got recorded in my nutrition-tracker app as “sad shchi”.

    So instead, fix the flaw by countering it if possible:

    • The meal is devoid of fiber? Preload with some dried figs (you can never have too many dried figs in your pantry)
    • The meal is high in saturated fat? Enjoy fiber before/during/after, per what’s convenient for you. Fiber helps clear out excess cholesterol, which is usually the main issue with saturated fat.
    • The meal is salty? Double down on your hydration before, during, and after. If that sounds like a chore, then remember, it’s more fun than getting bloated (which results, counterintuitively, from dehydration—because your body detects the salt, and panics and tries to retain as much water as possible to restore homeostasis, resulting in bloating) and hypertensive (which results from the combination of the blood having too much salt and too little water, and cells retaining too much water and pressing inwards because it is the cells themselves that are bloated). So, tending to your hydration can help mitigate all of the above.
    • The meal is full of high-GI carbs? Preload with fiber, enjoy the carbs together with fats, and have something acidic (e.g. some kind of vinegar, or citrus fruit) with it if that’s a reasonable option. Yes, this does mean that a Whiskey Sour is better for your blood sugars than an Old Fashioned, by the way, and/but no, it doesn’t make either of them healthy.
    • The meal is inflammatory? Doing all of the above things will help, as will eating it slowly/mindfully, which latter makes it less of a shock to your system.
