16/8 Intermittent Fasting For Beginners

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.

  • Body Sculpting with Kettlebells for Women – by Lorna Kleidman

    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.

    For those of us who are more often lifting groceries or pots and pans than bodybuilding trophies, kettlebells provide a way of training functional strength. This book does (as per the title) offer both sides of things—the body sculpting, and thebody maintenance free from pain and injury.

    Kleidman first explains the basics of kettlebell training, and how to get the most from one’s workouts, before discussing what kinds of exercises are best for which benefits, and finally moving on to provide full exercise programs.

    The exercise programs themselves are fairly comprehensive without being unduly detailed, and give a week-by-week plan for getting your body to where you want it to be.

    The style is fairly personal and relaxed, while keeping things quite clear—the photographs are also clear, though if there’s a weakness here, it’s that we don’t get to see which muscles are being worked in the same as we do when there’s an illustration with a different-colored part to show that.

    Bottom line: if you’re looking for an introductory course for kettlebell training that’ll take you from beginner through to the “I now know what I’m doing and can take it from here, thanks” stage.

  • Body by Science – by Dr. Doug McGuff & John Little

    The idea that you’ll get a re-sculpted body at 12 minutes per week is a bold claim, isn’t it? Medical Doctor Doug McGuff and bodybuilder John Little team up to lay out their case. So, how does it stand up to scrutiny?

    First, is it “backed by rigorous research” as claimed? Yes… with caveats.

    The book uses a large body of scientific literature as its foundation, and that weight of evidence does support this general approach:

    • Endurance cardio isn’t very good at burning fat
    • Muscle, even just having it without using it much, burns fat to maintain it
    • To that end, muscle can be viewed as a fat-burning asset
    • Muscle can be grown quickly with short bursts of intense exercise once per week

    Why once per week? The most relevant muscle fibers take about that long to recover, so doing it more often will undercut gains.

    So, what are the caveats?

    The authors argue for slow reps of maximally heavy resistance work sufficient to cause failure in about 90 seconds. However, most of the studies cited for the benefits of “brief intense exercise” are for High Intensity Interval Training (HIIT). HIIT involves “sprints” of exercise. It doesn’t have to be literally running, but for example maxing out on an exercise bike for 30 seconds, slowing for 60, maxing out for 30, etc. Or in the case of resistance work, explosive (fast!) concentric movements and slow eccentric movements, to work fast- and slow-twitch muscle fibers, respectively.

    What does this mean for the usefulness of the book?

    • Will it sculpt your body as described in the blurb? Yes, this will indeed grow your muscles with a minimal expenditure of time
    • Will it improve your body’s fat-burning metabolism? Yes, this will indeed turn your body into a fat-burning machine
    • Will it improve your “complete fitness”? No, if you want to be an all-rounder athlete, you will still need HIIT, as otherwise anything taxing your under-worked fast-twitch muscle fibers will exhaust you quickly.

    Bottom line: read this book if you want to build muscle efficiently, and make your body more efficient at burning fat. Best supplemented with at least some cardio, though!

    Yes, yes, we know, unplug once in a while. But what else do this highly-qualified pair of neuroscientists have to offer?

    Rather than being a book for the sake of being a book, with lots of fluff and the usual advice about single-tasking, the authors start with a reframe:

    Neurologically speaking, the hit of dopamine we get when looking for information is the exact same as the hit of dopamine that we, a couple of hundred thousand years ago, got when looking for nuts and berries.

    • When we don’t find them, we become stressed, and search more.
    • When we do find them, we are encouraged and search more nearby, and to the other side of nearby, and near around, to find more.

    But in the case of information (be it useful information or celebrity gossip or anything in between), the Internet means that’s always available now.

    So, we jitter around like squirrels, hopping from one to the next to the next.

    A strength of this book is where it goes from there. Specifically, what evidence-based practices will actually keep our squirrel-brain focused… and which are wishful thinking for anyone who lives in this century.

    Bringing original research from their own labs, as well as studies taken from elsewhere, the authors present a science-based toolkit of genuinely useful resources for actual focus.

    Bottom line: if you think you could really optimize your life if you could just get on track and stay on track, this is the book for you.

  • Felt Time – by Dr. Marc Wittmann

    This book goes far beyond the obvious “time flies when you’re having fun / passes slowly when bored”, or “time seems quicker as we get older”. It does address those topics too, but even in doing so, unravels deeper intricacies within.

    The author, a research psychologist, includes plenty of reference to actual hard science here, and even beyond subjective self-reports. For example, you know how time seems to slow down upon immediate apparent threat of violent death (e.g. while crashing, while falling, or other more “violent human” options)? We learn of an experiment conducted in an amusement park, where during a fear-inducing (but actually safe) plummet, subjective time slows down yes, but measures of objective perception and cognition remained the same. So much for adrenal superpowers when it comes to the brain!

    We also learn about what we can change, to change our perception of time—in either direction, which is a neat collection of tricks to know.

    The style is on the dryer end of pop-sci; we suspect that being translated from German didn’t help its levity. That said, it’s not scientifically dense either (i.e. not a lot of jargon), though it does have many references (which we like to see).

    Bottom line: if you’ve ever wished time could go more quickly or more slowly, this book can help with that.

  • Macadamia Nuts vs Brazil Nuts – 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 macadamia nuts to Brazil nuts, we picked the Brazil nuts.

    Why?

    They’re a lot more nutrient dense! But watch out…

    First, to do due diligence in terms of macros: Brazil nuts have twice as much protein and less fat, as well as being a little higher in fiber and slightly lower in carbs.

    In terms of vitamins, Brazil nuts are about 10x higher in vitamin E, while macadamias are somewhat higher in several B-vitamins.

    The category of minerals is where it gets interesting. Macadamia nuts are a little higher in iron and considerably higher in Manganese. But… Brazil nuts are a lot higher in calcium, copper, magnesium, phosphorus, potassium, selenium, and zinc.

    About that selenium… Specifically, it’s more than 5,000x higher, and a cup of Brazil nuts would give nearly 10,000x the recommended daily amount of selenium. Now, selenium is an essential mineral (needed for thyroid hormone production, for example), and at the RDA it’s good for good health. Your hair will be luscious and shiny. However, go much above that, and selenium toxicity becomes a thing, you may get sick, and it can cause your (luscious and shiny) hair to fall out. For this reason, it’s recommended to eat no more than 3–4 Brazil nuts per day.

    In short… Brazil nuts are much more nutrient dense in general, and thus come out on top here. But, they’re so nutrient dense in the case of selenium, that careful moderation is advised.

  • Meditation for Fidgety Skeptics – by Dan Harris

    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.

    If you already meditate regularly, this book isn’t aimed at you (though you may learn a thing or two anyway—this reviewer, who has practiced meditation for the past 30 years, learned a thing!).

    However, if you’re—as the title suggests—someone who hasn’t so far been inclined towards meditation, you could get the most out of this one. We’ll say more on this (obviously), but first, there’s one other group that may benefit from this book:

    If you have already practiced meditation, and/or already understand and want its benefits, but never really made it stick as a habit.

    Now, onto what you’ll get:

    • A fair scientific overview of meditation as an increasingly evidence-based way to reduce stress and increase both happiness and productivity
    • A good grounding in what meditation is and isn’t
    • A how-to guide for building up a consistent meditation habit that won’t get kiboshed when you have a particularly hectic day—or a cold.
    • An assortment of very common (and some less common) meditative practices to try
    • Some great auxiliary tools to build cognitive restructuring into your meditation

    We don’t usually cite other people’s reviews, but we love that one Amazon reviewer wrote:

    ❝I am 3 weeks into daily meditation practice, and I already notice that I am no longer constantly wishing for undercarriage rocket launchers while driving. I will always think your driving sucks, but I no longer wish you a violent death because of it. Yes, I live in Boston❞

    ~ J. Flaherty

    Bottom line: if you’re not already meditating daily, this is definitely a book for you. And if you are, you may learn a thing or two anyway!
