Capsaicin For Weight Loss And Against Inflammation

Capsaicin, found in hot peppers, has health benefits like aiding weight loss and reducing inflammation, but it may increase blood pressure. Start with a low dose of 2-6mg per day.
The potential health benefits of capsaicin, including weight loss and reduction of inflammation.

Capsaicin’s Hot Benefits

Capsaicin, the compound in hot peppers that makes them spicy, is a chemical irritant and a neurotoxin. However, humans being humans, we decided to eat them for fun.

In contrast to many other ways in which humans recreationally enjoy things that are objectively poisonous, consuming capsaicin (in moderation) is considered to have health benefits, such as aiding weight loss (by boosting metabolism) and reducing inflammation.

Let’s see what the science says…

First: is it safe?

Capsaicin is classified as “Generally Recognized As Safe”. That said, the same mechanism that causes them to boost metabolism, does increase blood pressure:

Mechanisms underlying the hypertensive response induced by capsaicin

If you are in good cardiovascular health, this increase should be slight and not pose any threat, unless for example you enter a chili-eating contest when not acclimated to such:

Capsaicin and arterial hypertensive crisis

As ever, if unsure, do check with your doctor first, especially if you are taking any blood pressure medications, or otherwise have known blood pressure issues.

Does it really boost metabolism?

It certainly does; it works by increasing oxygen consumption and raising body temperature, both of which mean more calories will be burned for the same amount of work:

Dietary capsaicin and its anti-obesity potency: from mechanism to clinical implications

This means, of course, that chili peppers enjoy the status of being functionally a “negative calorie” food, and a top-tier one at that:

Chili pepper as a body weight-loss food

Here’s a good quality study that showed a statistically significant* fat loss improvement over placebo:

Capsaicinoids supplementation decreases percent body fat and fat mass: adjustment using covariates in a post hoc analysis

*To put it in numbers, the benefit was:

  • 5.91 percentage points lower body fat percentage than placebo
  • 6.68 percentage points greater change in body fat mass than placebo

Does it really reduce inflammation?

Counterintuitive as it may seem, yes. By means of reducing oxidative stress. Given that things that reduce oxidative stress tend to reduce inflammation, and in turn tend to reduce assorted disease risks (from diabetes to cancer to Alzheimer’s), this probably has more knock-on benefits too, but we don’t have room to explore all of those today.

Fresh peppers are best for this, but dried peppers (such as when purchased as a ground spice in the supermarket, or when purchased as a capsule-based supplement) still have a very respectable anti-inflammatory effect:

How much should we take?

It’s recommended to start at a low dose and gradually increase it, but 2–6mg of capsaicin per day is the standard range used in studies.

If you’re getting this from peppers, then for example cayenne pepper (a good source of capsaicin) contains around 2.5mg of capsaicin per 1 gram of cayenne.

In the case of capsules, if for example you don’t like eating hot pepper, this will usually mean taking 2–6 capsules per day, depending on dosage.

Make sure to take it with plenty of water!

Where can we get it?

Fresh peppers or ground spice from your local grocery store is fine. Your local health food store probably sells the supplements, too.

If you’d like to buy it online, here is an example product on Amazon.

Note: options on Amazon were more limited than usual, so this product is not vegan, and probably not halal or kosher, as the capsule contains an unspecified gelatin.

  • Stop Cancer 20 Years Ago

    Dr. Jenn Simmons shares vital tips on preventing cancer and inflammation, advocating for lifestyle changes and proactive health management at any age.

    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.
