16/8 Intermittent Fasting For Beginners

Intermittent Fasting demystified: Learn why it eases metabolic load, fosters cell maintenance, and may reduce disease risk—with important caveats for diabetics.
A clock with a fork and knife on either side is depicted on the left side of the image. The words "16/8 Intermittent Fasting" appear to the right of the clock in bold, uppercase letters, perfect for beginners. The bottom right corner features the "10 almonds" logo with images of almonds.

Health Insider explains in super-simple fashion why and how to do Intermittent Fasting (IF), which is something that can sound complicated at first, but becomes very simple and easy once understood.

What do we need to know?

Intermittent fasting (IF) is a good, well-evidenced way to ease your body’s metabolic load, and
give your organs a chance to recover from the strain of digestion and its effects. That’s not just your gastrointestinal organs! It’s your pancreas and liver too, amongst others—this is about glucose metabolism as much as it is about digestion.

This, in turn, allows your body some downtime to do its favorite thing, which is: maintenance!

This maintenance takes the form of enhanced cellular apoptosis and autophagy, helping to keep cells young and cancer-free.

In other words, with well-practised intermittent fasting, we can reduce our risk of metabolic disease (including heart disease and diabetes) as well as cancer and neurodegeneration.

You may be wondering: this sounds miraculous; what’s the catch? There are a couple:

  • While fasting from food, the body’s enhanced metabolism requires more water, so you’ll need to take extra care keep on top of your hydration (this is one reason why Ramadan fasting, while healthy for most people, is not as healthy as IF—because Ramadan fasting means abstaining from water, too).
  • If you are diabetic, and especially if you have Type 1 Diabetes, fasting may not be a safe option for you, since if you get a hypo in the middle of your fasting period, it’s obviously not a good idea to wait another many hours before fixing it.

Extra note on that last one: it’s easy to think “can’t I just lower my bolus insulin instead of eating?” and while superficially yes that will raise your blood sugar levels, it’s because the sugar will be sticking around in your blood, and not actually getting released into the organs that need it. So while your blood glucose monitor may say you’re fine, you will be starving your organs and if you keep it up they may suffer serious damage.

Disclaimer: our standard legal/medical disclaimer applies, and this is intended for educational purposes only; please do speak with your endocrinologist before changing anything you usually do with regard to your blood sugar maintenance.

Ok, back onto the cheerier topic at hand:

Aside from the above: for most people, IF is a remarkably healthful practice in very many ways.

  • 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.
