Let’s burn! Metabolic tweaks and hacks

Our metabolism is, for as long as we live, a constantly moving thing. And it’s not a monolith either; there are parts of our metabolism that can speed up or slow down independently of others.

If we talk about metabolism without clarifying context, though, this is usually about one’s “basal metabolic rate”, that is, how many calories we burn just by being alive.

Why do we want to speed it up? Might we ever want to slow it down?

We might want to slow our metabolism down in survival circumstances, but generally speaking, a faster metabolism is a better one.

Yes, even when it comes to aging. Because although metabolism comes with metabolizing oxygen (which, ironically, tends to kill us eventually, since this is a key part of cellular aging), it is still beneficial to replace cells sooner rather than later. The later we replace a given cell (ie, the longer the cell lives), the more damaged it gets, and then the copy is damaged from the start, because the damage was copied along with it. So, best to have a fast metabolism to replace cells quickly when they are young and healthy.

A quick metabolism helps the body to do this.

Most people, of course, are interested in a fast metabolism to burn off fat, but beware: if you increase your metabolism without consideration to how and when you consume calories, you will simply end up eating more to compensate.

One final quick note before we begin:

Limitations

There’s a lot we can do to change our metabolism, but there are some things that may be outside of our control. They include:

  • Age—we can influence our biological age, but we cannot (yet!) halt aging, so this will happen
  • Body size—and yes we can change this a bit, but we all have our own “basic frame” to work with. Someone who is 6’6” is never going to be able to have the same lower-end-of-scale body mass of someone who is 5’0”, say.
  • Sex—this is about hormones, and HRT is a thing, but for example, broadly speaking, men will have faster metabolisms than women, because of hormonal differences.
  • Medical conditions—often also related to other hormones, but for example someone with Type 1 Diabetes is going to have a very different relationship with their metabolism than someone without, and someone with a hypo- or hyperactive thyroid will again have a very different metabolism in a way that that lifestyle factors can’t completely compensate for.

The tips and tricks

Intermittent fasting

Intermittent fasting has been found to, amongst other things, promote healthy apoptosis and autophagy (in other words: early programmed cell death and recycling—these are good things).

It also has anti-inflammatory benefits and decreases the risk of insulin resistance. In other words, intermittent fasting boosts the metabolism while simultaneously guarding against some of the dangers of a faster metabolism (harms you’d get if you instead increased your metabolism by doing intense exercise and then eating a mountain of convenience food to compensate)

Read the science: Intermittent Fasting: Is the Wait Worth the Weight?

Enjoy plenty of protein

This one won’t speed your metabolism up, so much as help it avoid slowing down as a result of fat loss.

Because of our body’s marvelous homeostatic system trying to keep our body from changing status at any given time, often when we lose fat, our body drops our metabolism to compensate, thinking we are in an ongoing survival situation and food is scarce so we’d better conserve energy (as fat). That’s a pain for would-be weight-loss dieters!

Eating protein can let our body know that we’re perfectly safe and not starving, so it will keep the metabolism ticking over nicely, without putting on fat.

Read the science: The role of protein in weight loss and maintenance

Stay hydrated

People think of drinking water as part of a weight loss program being just about filling oneself up, and that is a thing, but it also has a role to play in our metabolism. Specifically, lipolysis (the process of removing fat).

Because, we are mostly water. Not only is it the main content of our various body tissue cells, but also, of particular note, our blood (the means by which everything is transported around our body) is mostly water, too.

It’s hard for the body to keep everything ticking over like a well-oiled machine if its means of transportation is sluggish!

Take a stand

That basal metabolic rate we talked about?

  • If you’re lying down at rest, that’s what your metabolism will be like.
  • If you’re sitting up, it’ll be a little quicker, but not much.
  • If you’re standing, suddenly half your body is doing things, and you don’t even notice them because they’re just stabilizing muscles and the like, but on a cellular level, your body gets very busy.

Time to invest in a standing desk? Or a treadmill in front of the TV?

The spice of life

Capsaicin, the compound in many kinds of pepper that give them their spicy flavor, boosts the metabolism. In the words of Tremblay et al for the International Journal of Obesity:

❝[Capsaicin] stimulates the sympathoadrenal system that mediates the thermogenic and anorexigenic effects of capsaicinoids.

Capsaicinoids have been found to accentuate the impact of caloric restriction on body weight loss.

Some studies have also shown that capsinoids increase energy expenditure.

Capsaicin supplementation attenuates or even prevents the increase in hunger and decrease in fullness as well as the decrease in energy expenditure and fat oxidation, which normally result from energy restriction❞

Read for yourself: Capsaicinoids: a spicy solution to the management of obesity?

You snooze, you lose (fat)

While exercising is generally touted as the road to weight loss, and certainly regular exercise does have a part to play, doing so without good rest will have bad results.

In fact, even if you’re not exercising, if you don’t get enough sleep your metabolism will get sluggish to try to slow you down and encourage you to sleep.

So, be proactive, and make getting enough good quality sleep a priority.

Eat for metabolic health

Aside from the chilli peppers we mentioned, there are other foods associated with good metabolic health. We don’t have room to go into the science of each of them here, but here’s a well-researched, well-sourced standalone article listing some top choices:

  • Unlock Your Menopause Type – by Dr. Heather Hirsch

    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 featured Dr. Hirsch before, here, and mentioned this book which, at the time, we had not yet reviewed. So, here it is:

    What sets this apart from a lot of menopause books is that there’s a lot less “eat these foods and your body will magically stop exhibiting symptoms of menopause” and a lot more clinical observations and then evidence-based recommendations.

    Which is not to say don’t eat broccoli and almonds; by all means, they’re great foods and contain valuable nutrients that will help. But it is to say that if your doctor’s prescription is just broccoli and almonds, maybe have those as a snack while you’re looking for a second opinion.

    Dr. Hirsch goes through various “menopause types”, but it’s not so much “astrology for gynecologists” and more “here are clusters of menopause symptoms set against timeline of presentation, and they can be categorized into six main ways that between them, cover pretty much all my patients, which have been many”.

    So if you, dear reader, are menopausal (including peri- or post-), then the chances are very good that you will see yourself in one of those six sets.

    She then goes about how to prioritize relief and safety, and personalize a treatment plan, and maintain the best menopausal care for you, going forward.

    The style is easy-reading pop-science, punctuated by clinical science and 35 pages of references. She’s also, unlike a lot of authors in the genre, manifestly not invested in being a celebrity or making a personality cult out of her recommendations; she’s happy to stick to the science and put out good advice.

    Bottom line: if you or someone you love is menopausal (including peri- or post-), this is a top-tier book.

  • Without Medicare Part B’s Shield, Patient’s Family Owes $81,000 for a Single Air-Ambulance Flight

    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.

    Without Medicare Part B’s Shield, Patient’s Family Owes $81,000 for a Single Air-Ambulance Flight

    Debra Prichard was a retired factory worker who was careful with her money, including what she spent on medical care, said her daughter, Alicia Wieberg. “She was the kind of person who didn’t go to the doctor for anything.”

    That ended last year, when the rural Tennessee resident suffered a devastating stroke and several aneurysms. She twice was rushed from her local hospital to Vanderbilt University Medical Center in Nashville, 79 miles away, where she was treated by brain specialists. She died Oct. 31 at age 70.

    One of Prichard’s trips to the Nashville hospital was via helicopter ambulance. Wieberg said she had heard such flights could be pricey, but she didn’t realize how extraordinary the charge would be — or how her mother’s skimping on Medicare coverage could leave the family on the hook.

    Then the bill came.

    The Patient: Debra Prichard, who had Medicare Part A insurance before she died.

    Medical Service: An air-ambulance flight to Vanderbilt University Medical Center.

    Service Provider: Med-Trans Corp., a medical transportation service that is part of Global Medical Response, an industry giant backed by private equity investors. The larger company operates in all 50 states and says it has a total of 498 helicopters and airplanes.

    Total Bill: $81,739.40, none of which was covered by insurance.

    What Gives: Sky-high bills from air-ambulance providers have sparked complaints and federal action in recent years.

    For patients with private insurance coverage, the No Surprises Act, which went into effect in 2022, bars air-ambulance companies from billing people more than they would pay if the service were considered “in-network” with their health insurers. For patients with public coverage, such as Medicare or Medicaid, the government sets payment rates at much lower levels than the companies charge.

    But Prichard had opted out of the portion of Medicare that covers ambulance services.

    That meant when the bill arrived less than two weeks after her death, her estate was expected to pay the full air-ambulance fee of nearly $82,000. The main assets are 12 acres of land and her home in Decherd, Tennessee, where she lived for 48 years and raised two children. The bill for a single helicopter ride could eat up roughly a third of the estate’s value, said Wieberg, who is executor.

    The family’s predicament stems from the complicated nature of Medicare coverage.

    Prichard was enrolled only in Medicare Part A, which is free to most Americans 65 or older. That section of the federal insurance program covers inpatient care, and it paid most of her hospital bills, her daughter said.

    But Prichard declined other Medicare coverage, including Part B, which handles such things as doctor visits, outpatient treatment, and ambulance rides. Her daughter suspects she skipped that coverage to avoid the premiums most recipients pay, which currently are about $175 a month.

    Loren Adler, a health economist for the Brookings Institution who studies ambulance bills, estimated the maximum charge that Medicare would have allowed for Prichard’s flight would have been less than $10,000 if she’d signed up for Part B. The patient’s share of that would have been less than $2,000. Her estate might have owed nothing if she’d also purchased supplemental “Medigap” coverage, as many Medicare members do to cover things like coinsurance, he said.

    Nicole Michel, a spokesperson for Global Medical Response, the ambulance provider, agreed with Adler’s estimate that Medicare would have limited the charge for the flight to less than $10,000. But she said the federal program’s payment rates don’t cover the cost of providing air-ambulance services.

    “Our patient advocacy team is actively engaged with Ms. Wieberg’s attorney to determine if there was any other applicable medical coverage on the date of service that we could bill to,” Michel wrote in an email to KFF Health News. “If not, we are fully committed to working with Ms. Wieberg, as we do with all our patients, to find an equitable solution.”

    The Resolution: In mid-February, Wieberg said the company had not offered to reduce the bill.

    Wieberg said she and the attorney handling her mother’s estate both contacted the company, seeking a reduction in the bill. She said she also contacted Medicare officials, filled out a form on the No Surprises Act website, and filed a complaint with Tennessee regulators who oversee ambulance services. She said she was notified Feb. 12 that the company filed a legal claim against the estate for the entire amount.

    Wieberg said other health care providers, including ground ambulance services and the Vanderbilt hospital, wound up waiving several thousand dollars in unpaid fees for services they provided to Prichard that are normally covered by Medicare Part B.

    But as it stands, Prichard’s estate owes about $81,740 to the air-ambulance company.

    More from Bill of the Month

    The Takeaway: People who are eligible for Medicare are encouraged to sign up for Part B, unless they have private health insurance through an employer or spouse.

    “If someone with Medicare finds that they are having difficulty paying the Medicare Part B premiums, there are resources available to help compare Medicare coverage choices and learn about options to help pay for Medicare costs,” Meena Seshamani, director of the federal Center for Medicare, said in an email to KFF Health News.

    She noted that every state offers free counseling to help people navigate Medicare.

    In Tennessee, that counseling is offered by the State Health Insurance Assistance Program. Its director, Lori Galbreath, told KFF Health News she wishes more seniors would discuss their health coverage options with trained counselors like hers.

    “Every Medicare recipient’s experience is different,” she said. “We can look at their different situations and give them an unbiased view of what their next best steps could be.”

    Counselors advise that many people with modest incomes enroll in a Medicare Savings Program, which can cover their Part B premiums. In 2023, Tennessee residents could qualify for such assistance if they made less than $1,660 monthly as a single person or $2,239 as a married couple. Many people also could obtain help with other out-of-pocket expenses, such as copays for medical services.

    Wieberg, who lives in Missouri, has been preparing the family home for sale.

    She said the struggle over her mother’s air-ambulance bill makes her wonder why Medicare is split into pieces, with free coverage for inpatient care under Part A, but premiums for coverage of other crucial services under Part B.

    “Anybody past the age of 70 is likely going to need both,” she said. “And so why make it a decision of what you can afford or not afford, or what you think you’re going to use or not use?”

  • Bromelain vs Inflammation & Much More

    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 Fruity

    Bromelain is an enzyme* found in pineapple (and only in pineapple), that has many very healthful properties, some of them unique to bromelain.

    *actually a combination of enzymes, but most often referred to collectively in the singular. But when you do see it referred to as “they”, that’s what that means.

    What does it do?

    It does a lot of things, for starters:

    ❝Various in vivo and in vitro studies have shown that they are anti-edematous, anti-inflammatory, anti-cancerous, anti-thrombotic, fibrinolytic, and facilitate the death of apoptotic cells. The pharmacological properties of bromelain are, in part, related to its arachidonate cascade modulation, inhibition of platelet aggregation, such as interference with malignant cell growth; anti-inflammatory action; fibrinolytic activity; skin debridement properties, and reduction of the severe effects of SARS-Cov-2

    ~ Dr. Carolina Varilla et al.

    Some quick notes:

    • “facilitate the death of apoptotic cells” may sound alarming, but it’s actually good; those cells need to be killed quickly; see for example: Fisetin: The Anti-Aging Assassin
    • If you’re wondering what arachidonate cascade modulation means, that’s the modulation of the cascade reaction of arachidonic acid, which plays a part in providing energy for body functions, and has a role in cell structure formation, and is the precursor of assorted inflammatory mediators and cell-signalling chemicals.
    • Its skin debridement properties (getting rid of dead skin) are most clearly seen when using bromelain topically (one can literally just make a pineapple poultice), but do occur from ingestion also (because of what it can do from the inside).
    • As for being anti-thrombotic and fibrinolytic, let’s touch on that before we get to the main item, its anti-inflammatory properties.

    If you want to read more of the above before moving on, though, here’s the full text:

    Bromelain, a Group of Pineapple Proteolytic Complex Enzymes (Ananas comosus) and Their Possible Therapeutic and Clinical Effects. A Summary

    Anti-thrombotic and fibrinolytic

    While it does have anti-thrombotic effects, largely by its fibrinolytic action (i.e., it dissolves the fibrin mesh holding clots together), it can have a paradoxically beneficial effect on wound healing, too:

    Stem Bromelain Proteolytic Machinery: Study of the Effects of its Components on Fibrin (ogen) and Blood Coagulation

    For more specifically on its wound-healing benefits:

    In Vitro Effect of Bromelain on the Regenerative Properties of Mesenchymal Stem Cells

    Anti-inflammatory

    Bromelain is perhaps most well-known for its anti-inflammatory powers, which are so diverse that it can be a challenge to pin them all down, as it has many mechanisms of action, and there’s a large heterogeneity of studies because it’s often studied in the context of specific diseases. But, for example:

    ❝Bromelain reduced IL-1β, IL-6 and TNF-α secretion when immune cells were already stimulated in an overproduction condition by proinflammatory cytokines, generating a modulation in the inflammatory response through prostaglandins reduction and activation of cascade reactions that trigger neutrophils and macrophages, in addition to accelerating the healing process

    ~ Dr. Taline Alves Nobre et al.

    Read in full:

    Bromelain as a natural anti-inflammatory drug: a systematic review

    Or if you want a more specific example, here’s how it stacks up against arthritis:

    ❝The results demonstrated the chondroprotective effects of bromelain on cartilage degradation and the downregulation of inflammatory cytokine (tumor necrosis factor (TNF)-α, IL-1β, IL-6, IL-8) expression in TNF-α–induced synovial fibroblasts by suppressing NF-κB and MAPK signaling❞

    ~ Dr. Perephan Pothacharoen et al.

    Read in full:

    Bromelain Extract Exerts Antiarthritic Effects via Chondroprotection and the Suppression of TNF-α–Induced NF-κB and MAPK Signaling

    More?

    Yes more! You’ll remember from the first paper we quoted today, that it has a long laundry list of benefits. However, there’s only so much we can cover in one edition, so that’s it for today

    Is it safe?

    It is generally recognized as safe. However, its blood-thinning effect means it should be avoided if you’re already on blood-thinners, have some sort of bleeding disorder, or are about to have a surgery.

    Additionally, if you have an allergy, this one may not be for you.

    Aside from that, anything can have drug interactions, so do check with your doctor/pharmacist to be sure.

    Want to try some?

    You can just eat pineapples, but if you don’t enjoy that and/or wouldn’t want it every day, bromelain is available in supplement form too.

    We don’t sell it, but here for your convenience is an example product on Amazon

    Our Verdict

    When comparing beetroot to carrot, we picked the carrot.

    Why?

    It was close! And beetroot does have its advantages, but we say carrot wins on balance.

    In terms of macros, these two root vegetables are close to identical, down to both having 9.57g carbs per 100g, and 2.8g fiber per 100g. Technically, beetroot has a smidgen more protein, but nobody’s eating these for their tiny protein content.

    When it comes to vitamins, it’s not close and the margins are mostly huge: carrots have a lot more of vitamins A, B1, B2, B3, B5, B6, C, E, K, and choline, while beetroot has more vitamin B9.

    In the category of minerals, superficially it swings the other way, but the margins this time are small. Nevertheless, beetroot has more copper, iron, magnesium, manganese, phosphorus, potassium, selenium, and zinc, while carrots have more calcium.

    This would make things, on balance, a tie: equal on macros, carrots win on vitamins, beetroot wins on minerals.

    But because of the relative margins of difference, carrots win the day, because they’re almost as good as beetroot on those minerals, whereas beetroot doesn’t come close to carrot on the vitamins.

  • Citicoline: Better Than Dietary Choline?

    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.

    Citicoline: Better Than Dietary Choline?

    Citicoline, also known as cytidine diphosphate-choline (or CDP-Choline, to its friends, or cytidine 5′-diphosphocholine if it wants to get fancy) is a dietary supplement that the stomach can metabolize easily for all the brain’s choline needs. What are those needs?

    Choline is an essential nutrient. We technically can synthesize it, but only in minute amounts, far less than we need. Choline is a key part of the neurotransmitter acetylcholine, as well as having other functions in other parts of the body.

    As for citicoline specifically… it appears to do the job better than dietary sources of choline:

    ❝Intriguing data, showing that on a molar mass basis citicoline is significantly less toxic than choline, are also analyzed.

    It is hypothesized that, compared to choline moiety in other dietary sources such as phosphatidylcholine, choline in citicoline is less prone to conversion to trimethylamine (TMA) and its putative atherogenic N-oxide (TMAO).

    Epidemiological studies have suggested that choline supplementation may improve cognitive performance, and for this application citicoline may be safer and more efficacious.❞

    ~ Synoradzki & Grieb

    Source: Citicoline: A Superior Form of Choline?

    Great! What does it do?

    What doesn’t it do? When it comes to cognitive function, anyway, citicoline covers a lot of bases.

    Short version: it improves just about every way a brain’s healthy functions can be clinically measured. From cognitive improvements in all manner of tests (far beyond just “improves memory” etc; also focus, alertness, verbal fluency, logic, computation, and more), to purely neurological things like curing tinnitus (!), alleviating mobility disorders, and undoing alcohol-related damage.

    One of the reasons it’s so wide in its applications, is that it has a knock-on effect to other systems in the brain, including the dopaminergic system.

    Long version: Citicoline: pharmacological and clinical review, 2022 update

    (if you don’t want to sit down for a long read, we recommend skimming to the charts and figures, which are very elucidating even alone)

    Spotlight study in memory

    For a quick-reading example of how it helps memory specifically:

    Citicoline and Memory Function in Healthy Older Adults: A Randomized, Double-Blind, Placebo-Controlled Clinical Trial

    Keeping dementia at bay

    For many older people looking to improve memory, it’s less a matter of wanting to perform impressive feats of memory, and more a matter of wanting to keep a sharp memory throughout our later years.

    Dr. Maria Bonvicini et al. looked into this:

    ❝We selected seven studies including patients with mild cognitive impairment, Alzheimer’s disease or post-stroke dementia

    All the studies showed a positive effect of citicoline on cognitive functions. Six studies could be included in the meta-analysis.

    Overall, citicoline improved cognitive status, with pooled standardized mean differences ranging from 0.56 (95% CI: 0.37-0.75) to 1.57 (95% CI: 0.77-2.37) in different sensitivity analyses❞

    Source: Is Citicoline Effective in Preventing and Slowing Down Dementia?-A Systematic Review and a Meta-Analysis

    The researchers concluded “yes”, and yet, called for more studies, and of higher quality. In many such studies, the heterogeneity of the subjects (often, residents of nursing homes) can be as much a problem (unclear whether the results will be applicable to other people in different situations) as it is a strength (fewer confounding variables).

    Another team looked at 47 pre-existing reviews, and concluded:

    ❝The review found that citicoline has been proven to be a useful compound in preventing dementia progression.

    Citicoline has a wide range of effects and could be an essential substance in the treatment of many neurological diseases.

    Its positive impact on learning and cognitive functions among the healthy population is also worth noting.❞

    Source: Application of Citicoline in Neurological Disorders: A Systematic Review

    The dopamine bonus

    Remember how we said that citicoline has a knock-on effect on other systems, including the dopaminergic system? This means that it’s been studied (and found meritorious) for alleviating symptoms of Parkinson’s disease:

    ❝Patients with Parkinson’s disease who were taking citicoline had significant improvement in rigidity, akinesia, tremor, handwriting, and speech.

    Citicoline allowed effective reduction of levodopa by up to 50%.

    Significant improvement in cognitive status evaluation was also noted with citicoline adjunctive therapy.❞

  • The Magic of L-theanine

    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.

    All The Benefits Of Caffeine And More, Without The Drawbacks? What’s The Catch?

    It just takes one extra supplement.

    For many of us, our morning brew is practically a ritual, but caffeine can also cause all kinds of problems ranging from caffeine jitters to caffeine crashes to caffeine addiction and withdrawal. Surely, something could be better?

    Well, yes it could! You doubtlessly know about green tea’s antioxidant properties, but its amino acid, l-theanine (which can be taken as a supplement with coffee, if you don’t enjoy green tea) has so much more to offer:

    • L-theanine has been found to reduce stress responses—and let’s face it, when we most want/need a coffee is often when facing stress
    • It also reduces anxiety, making it a very safe “downer” without the problems of, for example, alcohol—or other potentially addictive substances
    • It’s far more than just that, though! Paradoxically, l-theanine also improves alertness (what other calming things promote alertness? Not so many)
    • Part of its trick is that it also improves accuracy—whereas stimulants like caffeine may produce a twitchy, jumpy, responsiveness, l-theanine’s signature effect is a calm state of sharp readiness. Caffeine works by stimulating the adrenal gland and increasing blood pressure, while simultaneously blocking adenosine receptors so that your body doesn’t notice its own tiredness—which is why you’re likely to crash later, when the tiredness that had been masked, all hits at once. Instead, l-theanine taken with caffeine acts as a moderator of that, making for a longer, gentler curve. In terms of subjective experience, what this can mean for many people is: no more caffeine jitters!
    • All this means that while l-theanine can boost all kinds of cognitive function, including alertness and accuracy, many like to take in the evening as it can also promote a good night’s sleep, ready to be at your best the next day.
    • How much to take? 200mg is a commonly used dosage, which in supplement terms is usually a single capsule. A lot easier to take than the 40 cups of green tea that this dosage would otherwise be!
