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:

    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

    ❝Questions?❞

    It seems that this week, everyone was so satisfied with our information, that we received no questions! (If you sent one and we somehow missed it, please accept our apologies and do bring our attention to it)

    However, we did receive some expert feedback that we wanted to share because it’s so informative:

    ❝I work at a detox rehab in Mexico, where we can use methods not legal in the United States. Therefore, while much of the linked articles had useful information, I’m in the “trenches” every day, and there’s some information I’d like to share that you may wish to share, with additional information:

    1. Buprenorphine is widely used and ineffective for addiction because it’s synthetic and has many adverse side effects. For heavy drug users it isn’t enough and they still hit the streets for more opioid, resulting in fentanyl deaths. Depending on length of usage and dose, it can take WEEKS to get off of, and it’s extremely difficult.
    2. Ibogaine is the medicine we use to detox people off opiates, alcohol, meth as well as my own specialty, bulimia. It’s psychoactive and it temporarily “resets” the brain to a pre-addictive state. Supplemented by behavior and lifestyle changes, as well as addressing the traumas that led to the addiction is extremely effective.

    Our results are about 50%, meaning the client is free of the substance or behavior 1 year later. Ibogaine isn’t a “magic pill” or cure, it’s an opening tool that makes the difficult work of reclaiming one’s life easier.

    Ibogaine is not something that should be done outside a medical setting. It requires an EKG to ensure the heart is healthy and doesn’t have prolonged QT intervals; also blood testing to ensure organs are functioning (especially the liver) and mineral levels such as magnetic and potassium are where they should be. It is important that this treatment be conducted by experienced doctors or practitioners, and monitoring vital signs constantly is imperative.

    I’m taking time to compose this information because it needs to be shared that there is an option available most people have not heard about.❞

    ~ 10almonds reader (slightly edited for formatting and privacy)

    Thank you for that! Definitely valuable information for people to know, and (if applicable for oneself or perhaps a loved one) ask about when it comes to local options.

    We see it’s also being studied for its potential against other neurological conditions, too:

    ❝The combination of ibogaine and antidepressants produces a synergistic effect in reducing symptoms of psychiatric disorders such as bipolar disorder, depression, schizophrenia, paranoia, anxiety, panic disorder, mania, post-traumatic stress disorder (PTSD), and obsessive–compulsive disorder. Though ibogaine and the antidepressant act in different pathways, together they provide highly efficient therapeutic responses compared to when each of the active agents is used alone.❞

  • What Most People Don’t Know About HIV

    What To Know About HIV This World AIDS Day

    Yesterday, we asked you to engage in a hypothetical thought experiment with us, and putting aside for a moment any reason you might feel the scenario wouldn’t apply for you, asked:

    ❝You have unprotected sex with someone who, afterwards, conversationally mentions their HIV+ status. Do you…❞

    …and got the above-depicted, below-described, set of responses. Of those who responded…

    • Just over 60% said “rush to hospital; maybe a treatment is available”
    • Just under 20% said “ask them what meds they’re taking (and perhaps whether they’d like a snack)”
    • Just over 10% said “despair; life is over”
    • Two people said “do the most rigorous washing down there you’ve ever done in your life”

    So, what does science say about it?

    First, a quick note on terms

    • HIV is the Human Immunodeficiency Virus. It does what it says on the tin; it gives humans immunodeficiency. Like many viruses that have become epidemic in humans, it started off in animals (called SIV, because there was no “H” involved yet), which were then eaten by humans, passing the virus to us when it one day mutated to allow that.
      • It’s technically two viruses, but that’s beyond the scope of today’s article; for our purposes they are the same. HIV-1 is more virulent and infectious than HIV-2, and is the kind more commonly found in most of the world.
    • AIDS is Acquired Immunodeficiency Syndrome, and again, is what it sounds like. When a person is infected with HIV, then without treatment, they will often develop AIDS.
      • Technically AIDS itself doesn’t kill people; it just renders people near-defenseless to opportunistic infections (and immune-related diseases such as cancer), since one no longer has a properly working immune system. Common causes of death in AIDS patients include cancer, influenza, pneumonia, and tuberculosis.

    People who contract HIV will usually develop AIDS if untreated. Untreated life expectancy is about 11 years.

    HIV/AIDS are only a problem for gay people: True or False?

    False, unequivocally. Anyone can get HIV and develop AIDS.

    The reason it’s more associated with gay men, aside from homophobia, is that since penetrative sex is more likely to pass it on…

    • If a man penetrates a woman and passes on HIV, that woman will probably not go on to penetrate someone else
    • If a man penetrates a man and passes on HIV, that man could go on to penetrate someone else—and so on
    • This means that without any difference in safety practices or promiscuity, it’s going to spread more between men on average, by simple mathematics.
    • This is why “men who have sex with men” is the generally-designated higher-risk category.

    There is medication to cure HIV/AIDS: True or False?

    False (though there have been individual case studies of gene treatments that may have cured people—time will tell).

    But! There are medications that can prevent HIV from being a life-threatening problem:

    • PrEP (Pre-Exposure Prophylaxis) is a medication that one can take in advance of potential exposure to HIV, to guard against it.
      • This is a common choice for people aren’t sure about their partners’ statuses, or people working in risky environments.
    • PEP (Post-Exposure Prophylaxis) is a medication that one can take after potential exposure to HIV, to “nip it in the bud”.
      • Those of you who were rushing to hospital in our poll, this is what you’re rushing there for.
    • ARVs (Anti-RetroVirals) are a class of medications (there are different options; we don’t have room to distinguish them) that reduce an HIV+ person’s viral load to undetectable levels.
      • Those of you who were asking what meds your partner was taking, these will be those meds. Also, most of them are to be taken in the morning with food, so that’s what the snack was for.

    If someone is HIV+, the risk of transmission in unprotected sex is high: True or False?

    True or False, with false being the far more likely. It depends on their medications, and this is why you were asking. If someone is on ARVs and their viral load is undetectable (as is usual once someone has been on ARVs for 6 months), they cannot transmit HIV to you.

    U=U is not a fancy new emoticon, it means “undetectable = untransmittable”, which is a mathematically true statement in the case of HIV viral loads.

    See: NIH | HIV Undetectable=Untransmittable (U=U)

    If you’re thinking “still sounds risky to me”, then consider this:

    You are safer having unprotected sex with someone who is HIV+ and on ARVs with an undetectable viral load, than you are with someone you are merely assuming is HIV- (perhaps you assume it because “surely this polite blushing young virgin of a straight man won’t give me cooties” etc)

    Note that even your monogamous partner of many decades could accidentally contract HIV due to blood contamination in a hospital or an accident at work etc, so it’s good practice to also get tested after things that involve getting stabbed with needles, cut in a risky environment, etc.

    If you’re concerned about potential stigma associated with HIV testing, you can get kits online:

    CDC | How do I find an HIV self-test?

    (these are usually fingerprick blood tests, and you can either see the results yourself at home immediately, or send it in for analysis, depending on the kit)

    If I get HIV, I will get AIDS and die: True or False?

    False, assuming you get treatment promptly and keep taking it. So those of you who were at “despair; life is over” can breathe a sigh of relief now.

    However, if you get HIV, it does mean you will have to take those meds every day for the rest of your (no reason it shouldn’t be long and happy) life.

    So, HIV is definitely still something to avoid, because it’s not great to have to take a life-saving medication every day. For a little insight as to what that might be like:

    HIV.gov | Taking HIV Medication Every Day: Tips & Challenges

    (as you’ll see there, there are also longer-lasting injections available instead of daily pulls, but those are much less widely available)

    Summary

    Some quick take-away notes-in-a-nutshell:

    • Getting HIV may have been a death sentence in the 1980s, but nowadays it’s been relegated to the level of “serious inconvenience”.
    • Happily, it is very preventable, with PrEP, PEP, and viral loads so low that they can’t transmit HIV, thanks to ARVs.
    • Washing will not help, by the way. Safe sex will, though!
      • As will celibacy and/or monogamy in seroconcordant relationships, e.g. you both have the same (known! That means actually tested recently! Not just assumed!) HIV status.
    • If you do get it, it is very manageable with ARVs, but prevention is better than treatment
    • There is no certain cure—yet. Some people (small number of case studies) may have been cured already with gene therapy, but we can’t know for sure yet.

  • Chai-Spiced Rice Pudding

    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.

    Sweet enough for dessert, and healthy enough for breakfast! Yes, “chai tea” is “tea tea”, just as “naan bread” is “bread bread”. But today, we’re going to be using the “tea tea” spices to make this already delicious and healthy dish more delicious and more healthy:

    You will need

    • 1 cup wholegrain rice (a medium-length grain is best for the optimal amount of starch to make this creamy but not sticky)
    • 1½ cups milk (we recommend almond milk, but any milk will work)
    • 1 cup full fat coconut milk
    • 1 cup water
    • 4 Medjool dates, soaked in hot water for 5 minutes, drained, and chopped
    • 2 tbsp almond butter
    • 1 tbsp maple syrup (omit if you prefer less sweetness)
    • 1 tbsp chia seeds
    • 2 tsp ground sweet cinnamon
    • 1 tsp ground ginger
    • 1 tsp vanilla extract
    • ½ tsp ground cardamom
    • ½ tsp ground nutmeg
    • ½ ground cloves
    • Optional garnish: berries (your preference what kind)

    Method

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

    1) Add all of the ingredients except the berries into the cooking vessel* you’re going to use, and stir thoroughly.

    *There are several options here and they will take different durations:

    • Pressure cooker: 10 minutes at high pressure (we recommend, if available)
    • Rice cooker: 25 minutes or thereabouts (we recommend only if the above or below aren’t viable options for you)
    • Slow cooker: 3 hours or thereabouts, but you can leave it for 4 if you’re busy (we recommend if you want to “set it and forget it” and have the time; it’s very hard to mess this one up unless you go to extremes)

    Options that we don’t recommend:

    • Saucepan: highly variable and you’re going to have to watch and stir it (we don’t recommend this unless the other options aren’t available)
    • Oven: highly variable and you’re going to have to check it frequently (we don’t recommend this unless the other options aren’t available)

    2) Cook, using the method you selected from the list.

    3) Get ready to serve. Depending on the method, they may be some extra liquid at the top; this can just be stirred into the rest and it will take on the same consistency.

    4) Serve in bowls, with a berry garnish if desired:

    Enjoy!

    Jim Kwik: from broken brain to brain coach

    Jim Kwik is a renowned expert in brain training and building mental resilience. With his innovative techniques and physical exercises, Jim Kwik helps individuals enhance their brain power and unlock their full potential.
    Image from Kwik Learning

    This is Jim Kwik. He suffered a traumatic brain injury as a small child, and later taught himself to read and write by reading comic books. He became fascinated with the process of learning, and in his late 20s he set up Kwik Learning, to teach accelerated learning in classrooms and companies, which he continued until 2009 when he launched his online learning platform. His courses have now been enjoyed by people in 195 countries.

    So, since accelerated learning is his thing, you might wonder…

    What does he have to share that we can benefit from in the next five minutes?

    Three brain exercises to improve memory and concentration

    A lot of problems we have with working memory are a case of executive dysfunction, but there are tricks we can use to get our brains into gear and make them cumulatively stronger:

    First exercise

    You can strengthen your corpus callosum (the little bridge between the two hemispheres of the brain) by performing a simple kinesiological exercise, such as alternating touching your left elbow to your right knee, and touching your right elbow to your left knee.

    Do it for about a minute, but the goal here is not a cardio exercise, it’s accuracy!

    You want to touch your elbow and opposite knee to each other as precisely as possible each time. Not missing slightly off to the side, not falling slightly short, not hitting it too hard.

    Second exercise

    Put your hands out in front of you, as though you’re about to type at a keyboard. Now, turn your hands palm-upwards. Now back to where they were. Now palm-upwards again. Got it? Good.

    That’s not the exercise, the exercise is:

    You’re now going to do the same thing, but do it twice as quickly with one hand than the other. So they’ll still be flipping to the same basic “beat”, put it in musical terms, the tempo on one hand will now be twice that of the other. When you get the hang of that, switch hands and do the other side.

    This is again about the corpus callosum, but it’s now adding an extra level of challenge because of holding the two rhythms separately, which is also working the frontal lobe of the cerebral cortex.

    The pre-frontal cortex in particular is incredibly important to executive function, self-discipline, and being able to “do” delayed gratification. So this exercise is really important!

    Third exercise

    This one works the same features of the brain, but most people find it harder. So, consider it a level-up on the previous:

    Imagine there’s a bicycle wheel in front of you (as though the bike is facing you at chest-height). Turn the wheel towards you with your hands, one on each side.

    Now, do the same thing, but each of your hands is going in the opposite direction. So one is turning the wheel towards you; the other is turning it away from you.

    Now, do the same thing, but one hand goes twice as quickly as the other.

    Switch sides.

    Why is this harder for most people than the previous? Because the previous involved processing discrete (distinct from each other) movements while this one involves analog continuous movements.

    It’s like reading an analog clock vs a digital clock, but while using both halves of your brain, your corpus callosum, your pre-frontal cortex, and the motor cortex too.

  • Kumquat vs Persimmon – 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 kumquat to persimmon, we picked the kumquat.

    Why?

    In terms of macros, kumquats have more protein, though like most fruits, it’s unlike anybody’s eating them for the protein content. More importantly, they have a lot more fiber, for less than half the carbs. It bears mentioning though that (again, like most fruits) persimmon isn’t bad for this either, and both fruits are low glycemic index foods.

    When it comes to vitamins, it’s not close: kumquats have more of vitamins A, B1, B2, B3, B5, B6, B9, E, and choline, while persimmon has more vitamin C. It’s worth noting that kumquats are already a very good source of vitamin C though; persimmon just has more.

    In the category of minerals, kumquats again lead with more calcium, copper, magnesium, manganese, and zinc, while persimmon has more iron, phosphorus, and potassium.

    In short, enjoy both, and/or whatever fruit you enjoy the most, but if looking for nutritional density, kumquats are bringing it.

  • The Surprising Link Between Type 2 Diabetes & Alzheimer’s

    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 Surprising Link Between Type 2 Diabetes & Alzheimer’s

    This is Dr. Rhonda Patrick. She’s a biomedical scientist with expertise in the areas of aging, cancer, and nutrition. In the past five years she has expanded her research of aging to focus more on Alzheimer’s and Parkinson’s, as she has a genetic predisposition to both.

    What does that genetic predisposition look like? People who (like her) have the APOE-ε4 allele have a twofold increased risk of Alzheimer’s disease—and if you have two copies (i.e., one from each of two parents), the risk can be up to tenfold. Globally, 13.7% of people have at least one copy of this allele.

    So while getting Alzheimer’s or not is not, per se, hereditary… The predisposition to it can be passed on.

    What’s on her mind?

    Dr. Patrick has noted that, while we don’t know for sure the causes of Alzheimer’s disease, and can make educated guesses only from correlations, the majority of current science seems to be focusing on just one: amyloid plaques in the brain.

    This is a worthy area of research, but ignores the fact that there are many potential Alzheimer’s disease mechanisms to explore, including (to count only mainstream scientific ideas):

    • The amyloid hypothesis
    • The tau hypothesis
    • The inflammatory hypothesis
    • The cholinergic hypothesis
    • The cholesterol hypothesis
    • The Reelin hypothesis
    • The large gene instability hypothesis

    …as well as other strongly correlated factors such as glucose hypometabolism, insulin signalling, and oxidative stress.

    If you lost your keys and were looking for them, and knew at least half a dozen places they might be, how often would you check the same place without paying any attention to the others?

    To this end, she notes about those latter-mentioned correlated factors:

    ❝50–80% of people with Alzheimer’s disease have type 2 diabetes; there is definitely something going on❞

    There’s another “smoking gun” for this too, because dysfunction in the blood vessels and capillaries that line the blood-brain barrier seem to be a very early event that is common between all types of dementia (including Alzheimer’s) and between type 2 diabetes and APOE-ε4.

    Research is ongoing, and Dr. Patrick is at the forefront of that. However, there’s a practical take-away here meanwhile…

    What can we do about it?

    Dr. Patrick hypothesizes that if we can reduce the risk of type 2 diabetes, we may reduce the risk of Alzheimer’s with it.

    Obviously, avoiding diabetes if possible is a good thing to do anyway, but if we’re aware of an added risk factor for Alzheimer’s, it becomes yet more important.

    Of course, all the usual advices apply here, including a Mediterranean diet and regular moderate exercise.

    Three other things Dr. Patrick specifically recommends (to reduce both type 2 diabetes risk and to reduce Alzheimer’s risk) include:

    (links are to her blog, with lots of relevant science for each)

    You can also hear more from Dr. Patrick personally, as a guest on Dr. Peter Attia’s podcast recently. She discusses these topics in much greater detail than we have room for in our newsletter:
