Hit the Hay

As ever, the Composite research, coding, and field-testing continues. And, in an interesting confluence of events, I stumbled across a research paper today that perfectly lines up with something I’ve recently experienced anecdotally in my own life.

For a while, I’ve been playing with biometric data sources that track fatigue and training status, so the Composite algorithm can square a theoretically ideal workout plan (heavy back squats today at 85% of my max) with the ever-changing reality of day-to-day life (I’m feeling run-down this morning, slept terribly, and think I might be coming down with a cold – better reduce the weight of those squats). And, actually, I’ve been making a bunch of progress on that front, measuring things like daily increase / decrease in grip strength (using a device called a dynamometer, which research shows correlates well with central nervous system fatigue), and tracking heart rate variability (using the excellent HRV4Training app to collect similarly research-backed data).

But, thus far, though I’d wanted to track sleep, too, most of the iPhone apps I’d found to do so were pretty much garbage. Though they all kicked out impressive-looking visualizations, they were often demonstrably incorrect – apps would show me deep in REM sleep when I knew I’d actually been awake and headed to the bathroom to pee.

So, on a friends recommendation, I bit the bullet, downloaded the Apple Watch app AutoSleep, and figured out an early-evening charging schedule that let me wear my watch to bed rather than just charging it overnight. And, in short, AutoSleep is pretty amazing – both in the detail it provides, and the accuracy with which it does so. Even if I end up just passing out for a nap on the couch without meaning to midday, the app somehow accurately senses when I do, and kicks out a ton of related data about the siesta.

From my first month of AutoSleep, however, I made an unhappy discovery: I sleep much less each night than I’d previously thought. Before, I would have said that I get 7 to 7 1/2 hours nightly. But, it turns out, that’s how long I spend in bed, trying to sleep; I’m actually out cold for only 85-90% of that time – more like 6 or 6 1/2 hours – once I factor in falling asleep, and waking for random small pockets throughout the night.

Even so, it turns out I may still be doing better than most. As I mentioned, I found a study this morning which estimates most people only really sleep about 80% of the time they’re trying to do so. Getting 7 1/2 hours of shuteye therefore probably requires shooting for a whopping 9.

If you want an accurate sense of how much sleep you really get yourself, and you happen to own an Apple Watch, I’d suggest you, too, download AutoSleep and check things out. And, if you don’t, but are serious about sleep for performance and health, you should probably assume you’re not too far from the rest of us, and add some substantial padding to your sleep time, Netflix be damned.

Classy

As I mentioned previously, I recently started testing Composite with clients in the real world. Which has gotten off to an excellent start. Enough so, in fact, that I’m already putting the pieces in place to start doing small-group classes there by the start of next month.

Fortuitously, Jess is off in North Carolina for the weekend, celebrating a belated Mother’s Day with her mom, sister, and two adorable nieces. And though I’m sad not to spend the weekend with her – because every day is way more excellent when I’m by her side – I’m also grateful for the 72 hours of nonstop work time.

So, while the rest of the world is barbecuing and enjoying the pre-summer sun, I’m on lockdown indoors, brainstorming and planning and coding away. And I’m totally thrilled.

HMB

Recently, a friend’s mother ended up in the hospital after taking a fall on some ice.  Although she was banged up pretty badly, fortunately, it looks like she’ll be fine.  Though, to play it safe, she was put on a week or two of bed rest.  I recommended she take the supplement HMB for the next few weeks, which my friend had never heard of before.  I’m sharing more about it here, on the chance it’s new to you, too, and might similarly be helpful in the future for you or for someone you love.

In short, beta-hydroxy-beta-methylbutyrate, or HMB, is a derivative of the essential amino acid Leucine.  It’s been widely studied, and it’s extremely safe.  You can find it cheaply at GNC or other supplement stores, as well as online.  Mostly, it’s been researched as a supplement for athletes, as it prevents protein breakdown, inhibiting something called the ubiquitin-proteasome pathway.  The results there are pretty clear: if you’re just starting or re-starting an exercise program, taking 3g of HMB a day significantly increases initial strength and muscle gains, while also reducing soreness and muscle damage.  In that context, definitely worthwhile.

However, more recently, HMB has also been studied for its ability to prevent muscle loss during periods of inactivity.  Turns out, it’s extremely effective in a situation like my friend’s mom’s.  One study followed older adults during 10 days of complete bed rest.  Those given just a placebo lost 4.5 pounds of lean mass over those ten days.  Which is a lot; in most cases, it would take nearly a year of training to gain that muscle back.  Conversely, those given 3g a day of HMB only lost 0.37 pounds of lean mass over the ten days – barely any at all.

So, regardless of your age, if you end up unexpectedly incapacitated – or even if you just hit a crazy patch of life and realize you’re going to have to take a month or two off of your regular workout routine – consider taking HMB.  It’s safe, it’s cheap.  And, as research shows, it works.

Somnambulant

For most of the last fifteen years, I’ve averaged about six, maybe six and a half hours of sleep a night.  And, honestly, that always seemed like enough.  I woke up before my alarm clock, and felt like I was functioning totally fine.

With each year, I read more and more research about the negative impact of insufficient sleep, the countless adverse consequences that slowly accrue if you don’t hold to seven and a half or eight hours nightly.  But, as I said, I felt okay, so I tended to shrug all that research off.

Then, eventually, I came across a study on the cognitive effects – as well as the perceived cognitive effects – of lack of sleep.  The researchers started out by getting a group of people caught up on sleep/well rested.  Then, for one night, they had the subjects cut back, sleeping six hours rather than eight, and assessed them with a battery of cognitive tests the following day.  Further, they then asked the subjects how they thought they had done on the tests.

After that first night of short sleep, the people reported feeling tired, and assumed they had performed worse on the tests than when they were sharp and rested.  And, indeed, they were correct.

Then, a second night in a row, they slept for just six hours.  Once again, they thought their scores had further declined, and once again, they were right.

Third night, third day, same thing.

But then, the fourth day!  For yet another night, the people slept six hours, and for yet another day, they took a battery of tests.  Except, this time, the people felt totally fine.  As they explained to the researchers, they had finally adjusted to the shorter nights of sleep.  They were back to feeling good, and they knew their scores were back up, too.

Problem was, they were completely wrong.  Just as before, their scores continued to decline with each day of sleep deprivation.  But after the fourth day or so, they simply lost the ability to recognize as much any longer.

That study definitely gave me pause, made me question my own self-assessment of how well I was functioning on my standard six hours and change.  Enough so that, despite a decade and a half of habit to the contrary, I decided it was worth some self-experimentation.  I made some serious lifestyle shifts, and started sleeping a full seven and a half or eight hours every single night.

And, actually, for the most part, I felt pretty much exactly the same as I did before.  But then, every so often, I ended up once again short-sleeping, and I felt terrible enough to realize the necessity of the shift.

I was thinking about that today, because for the past two nights I stayed up way past my bedtime, unable to put down a good book.  And while I don’t really regret that (in the words of Lincoln, “it’s been my experience that those with no vices have very few virtues”), I now definitely feel the effects of those two six-ish hour nights.  I’m sluggish, foggy, cranky, craving sweets, and ready for a nap.  In short, I feel like crap.

And, at the same time, I don’t mind at all.  As ever, it’s a good reminder that those extra hours snoozing aren’t wasted.  Despite years of convincing myself to the contrary, I really do need seven and a half or eight hours of sleep to be at my best.

With that, I’m off to bed.

KISS Weight Loss – Habit 3

Okay!  So, previously, we looked at two super easy, yet surprisingly effective weight loss hacks: drinking 16oz of water a half-hour before meals, and downsizing your plates.  Either of which, extrapolating from published research, could help you drop 10 pounds over the course of the year.

Fair enough.  Still, while both are effective, they’re also pretty finite in scope.  So, today, I’m sharing a hack with much broader implications, something you can use at pretty much every meal for the rest of your life.

When people get serious about nutrition, they’ll often set out counting calories – both to clock an overall number, and to perfectly balance the macronutrients (the protein, fats, and carbs) in their meals.  And, indeed, that’s an effective approach.  For the very short term.  However, in practice, it turns out to be wildly unsustainable; pretty much everybody quits doing it entirely, reverting to their old ways whether after two days, two weeks, or (if they’re particularly gung-ho) two months.

Fortunately, however, you can get 90%+ of the results, much more sustainably, by using a simpler approach instead: measuring things with your hand.  With a handful (pun intended) of rules, you can figure out the size and composition of optimally healthful meals.  Which has a few big advantages.  First, you take your hands with you most places you go.  And, second, they come already scaled relative to your overall size, which makes them perfectly customized to your specific nutritional needs.

Here’s how it works:

– Your palm (the size and thickness) is a serving of protein.

– Your first (balled up) is a serving of non-starchy vegetables.

– Your cupped hand (or, rather, what you can hold in it) is a serving of starchy carbs.

– Your thumb (length, width) is a serving of healthy fats.

Women need one of each of those to make a meal – one palm of protein, one fist of veggies, one cupful of starches, and a thumb of fat.  Men need two of each.

So, Abigail might eat a palm-sized piece of salmon, a fist-sized serving of broccoli, a cupped hand’s worth of rice, with a thumb of olive oil drizzled on the broccoli and salmon.

Or Bob might have a piece of steak the size of two palms, two fists of sauteed spinach, and two cupped hands of mashed potatoes, mixed with a thumb’s worth of butter.

And maybe they have brunch together, with one or two servings respectively of scrambled eggs (palm), a green salad (fist), a sweet potato hash (cupped hand) and some avocado (thumb).

The possibilities are endless.  And the process is as easy – and handy – as it gets.

Minimum Viable Fitness

Old joke:
First fish says, “how about all this water!”
Second fish replies, “what’s water?”

I know, not a great joke. But, actually, a pretty good reminder when starting a company.  And one I overlooked in the case of Composite, until Jess made some wise comments a few weeks back that helped get me onto a better, broader track.

I should first note that the startup/fish/water problem already gets a lot of coverage, at least in the San Francisco tech world.  There, 20-year-old tech dudes developing apps apparently gradually forget that there are other people in the world aside from other 20-year-old tech dudes developing apps, leading them to focus their energy solely on startups that solve their own problems.  Hence the spate of companies focused on becoming an Uber for laundry, and the like.

But, in fitness, the same kind of thing tends to happen.  From my observation, I’d estimate that about 5-10% of the US population sees exercise or fitness as a primary hobby, or a core part of their identity.  And I’d guess another 5-10% aspire in that direction, even if they’re not currently fully immersed.  And then there’s everyone else: the other 80-90% of the country who would like to be fit and healthy, but for whom that’s just one priority among hugely many, one obligation they can try to wedge into an already crazy busy schedule and life.

When fitness startups pop up, however, they tend to come from people already entirely surrounded by other people in that deeply fitness-committed 5-10%.  And so they essentially preach to the choir, solving the problem of how you might make that 5-10% even fitter, more deeply engaged.  (On rare occasion, companies do pop up targeting the non-enthusiast majority.  However, they tend to do that through savvy branding and messaging, rather than actually tailoring the underlying product or service.  Consider Planet Fitness, which has been hugely fiscally successful, yet whose members I would guess make even less forward progress as a whole than the already dismal results for gym members overall.)

Anyway, as I’ve been putting together Composite’s algorithm, I’ve too much been a water-ignorant fish, solely wearing my fitness-insider hat.  I pondered questions like: will members want to come in to the physical gym three or four times a week?  And what if they’re avid runners, and want to do some 5k or marathon training on top of that; how many times should they do that each week, too?

All of which is excellent and valuable and will be greatly appreciated by the insider crowd.  But the real question is, what about someone who can only commit to coming one time a week?  With the right guidance, maybe they’d also be willing to do two more 15-minute sessions at home during the balance of the week.  So given those parameters, for that person, can we still make a big impact?

Fortunately, I absolutely think we can.  It just takes a very focused, scaled down approach.  And the big upside of the AI-plus-human-coach model is that we can seamlessly go in either direction, personalizing to individual needs.  In fact, we can even scale up and down over time for the same person: maybe you have a busy stretch at work this winter, and want to pull back, but then in the spring, you’ve always wanted to do a Tough Mudder and you want to look good for a big upcoming beach trip at the start of the summer.  Perfect.  We can do any and all of that.  Or, at least, we should be able to.

And that’s what I’m working on at the moment.  Though the Composite algorithm is getting better and better, this week I went back to the drawing board, to start thinking about the changes and additions we’d have to make to expand it to really work for EVERYBODY, rather than for just the hardcore fitness few.  Sure, we may still start out with a beachhead model, bringing in the fitness-obsessed first and expanding out over time.  But just having that goal in mind gives me all kinds of ideas, things I want to work on, and small tweaks to the setup that I need to bake in from the start.

If I had to come up with a Good to Great-esque Big, Hairy, Audacious Goal for Composite, it would be to eventually make a statistically significant impact on health outcomes for the US as a whole.  And making sure we set out from the beginning asking how we’ll one day move beyond the NYC workout crowd is certainly the only way we even have a chance of getting there.

KISS Weight Loss –Habit 2

Last month, I shared the first in a series of super easy changes you can make to help lose weight: drink 16oz of water, 30 minutes before each meal.  In one study, over the course of 12 weeks, that one change was enough to help participants lose an average of 10.5 pounds.

Small, but powerful.  So let’s keep it going, with this month’s simple but effective habit!  Which is:

Use a smaller plate.

Thanks to something called the Delboeuf Illusion, your brain perceives the size of a thing in comparison to its surroundings.  As a result, people tend to use the size of their plate as an unconscious cue as they pile on food, covering, say, 2/3 of any given plate as what seems like a reasonable serving.  Thus, when you use smaller plates, you end up serving yourself less by default.  According to one study from Cornell and Georgia Tech, moving from a 12-inch plate to a 10-inch plate led people to serve themselves 22% fewer calories.  Do that just at dinners over the course of a year, and you’ll lose about 10 pounds!

That’s it.  So now you’re up to two habits: drink a big glass of water a half hour before each meal, and then eat those meals on slightly smaller plates.  Crazy enough, those alone should start to make a real difference over the next month.  Tune in four weeks from now for dumb but impactful KISS habit number three!

KISS Weight Loss – Intro + Habit #1

In the gym world, while the first week of January may be the busiest time of year, the start of September is a pretty close second.  Summer winds down, people come back to work, the school year boots up, and everyone generally seems to be ready to buckle down and make some change in their lives.

All too often, however, people set out on that road by making a bunch of big changes.  They completely revamp their diets.  They start working out five or six times a week.  And for a few weeks, it goes like gangbusters.  But by a month in, almost all of them have fallen off the wagon, reverting back to their original habits.  Because – as both the research and most people’s direct experience shows – large-scale, all-at-once change is extremely difficult to sustain.  And much like tooth-brushing, fitness habits really on help so long as you’re actively keeping them up.

But here’s the good new: there are a bunch of small changes that are surprisingly effective, and highly sustainable.  I’ve been researching a ton of them for Composite, and I’m going to start sharing them here, too: simple things you can do that make a disproportionately large impact on your fitness and health.

To encourage you to actually put these suggestions into use, I’ll be posting them one a month.  That gives you thirty days to actively focus on one behavior, baking it into unconscious and automatic habit by the time you start on the next one a month later.

Here we go.

KISS Weight Loss Habit #1

This one’s as simple as it gets:

30 minutes before each meal, drink 16oz of water.

That’s it.

But according to a recent study in Obesity, just that single, stupidly easy intervention allowed subjects to lose an average of 10.5 pounds in 12 weeks.  (!!!)

I’ll skip over the science (which hinges on tricking your brain’s satiety sensing system), and stick with the simplicity theme.  A big glass of water, a half hour before you eat.  That’s it.  But that alone is enough to jump-start serious weight loss.  Try it for a month, and then check in again for the next one.

Plus or Minus 2.5

Here’s a depressing fact: the average American gains about two and a half pounds each and every year.  Which means, over the decades, you can probably expect to slowly balloon up to increasingly ill health.

Of course, there are a slew of ways you can counter that upward trend, from healthier eating to walking more each day.  But there’s one hugely effective approach that people often overlook: building some muscle.

Unlike fat – which just sits there – muscle is metabolically active.  Which means that, just by existing, muscle burns calories.  A pound of muscle, in fact, burns about 10 calories a day.  And while that may not sound like much, it adds up surprisingly quickly.  Over the course of a year, each pound of added muscle burns off a pound of fat.

Thus, if you put on just five pounds of new muscle in one year, you would burn off five pounds of fat annually after that.  That’s enough to not only offset the average 2.5-pound gain, but also to help you lose 2.5 pounds each and every year instead.  In other words, as the decades added up and everyone else slid downhill, you’d be getting ever healthier, and looking increasingly good naked, instead.

Normally when I mention this to anyone over even just 30 years old, they tell me they’re too old to get started on lifting weights.  But as a great recent study showed, men in their mid to late 90’s, beginning strength training for the first time, still managed to build substantial strength and put on new muscle mass in just twelve weeks.  So, really, you don’t have any excuse.

In fact, research seems to be showing that strength training positively impacts pretty much every aspect of health and is possibly the single best way to ‘die young as late as possible’.  Yet, for whatever reason, the majority of exercisers still tend to pick up cardio training first (along with maybe some stretching), while overlooking strength training entirely.

But if you do what the majority does, you’ll get what the majority gets; and, here in America, in terms of bodyweight and general health, that’s probably not what you want.  So, buck the trend, and add in a couple of short strength training sessions each week.

+++

A quick addendum:

In discussion with friends here today, I was reminded that there’s often confusion about what actually constitutes strength training, and about how people gain muscle.  To make a long story short, it boils down to something called ‘progressive overload’ – essentially, lifting incrementally more weight over time.  If you can press ten-pound dumbbells overhead today, and are still pressing those same dumbbells in six months, you haven’t gotten any stronger, and you won’t gain any of that fat-burning, health-promoting new muscle you want.  Instead, you need to build to twelve then fifteen then twenty-pound dumbbells over future months to see results.

That’s hardly a new revelation.  It dates back at least to the 6th Century BC, when Milo of Crete became the most famous athlete in all of Greece after winning the gold medal in wrestling (the big deal sport at the time) six Olympics in a row.  He was a farm boy and had trained by picking

In the Wee Small Hours

For the last year or two, I’ve been starting each quarter with five days of Fast-Mimicking Diet, a low calorie (1000C on the first day, 700C each on days two-five), low protein quasi-fast that research is increasingly backing as a great tool for cancer prevention, longevity, and general health.  This quarter, I started the FMD a few days early, at the end of June, so I’d be done in time to BBQ binge on the 4th.  And, as per usual, I also used the FMD as a chance to take a week off from the gym, both because I think an intermittent complete break from training is wise in general, and because it’s almost a necessity for me given the week’s calorie restriction versus my normal, fast-metabolism-driven ‘human garbage disposal’ eating style.

Most quarters, however, I still do a bunch of walking during my FMD-ing.  But as my previously-mentioned knee tweak is still on the mend, without really meaning to, I’d also temporarily dropped from my usual daily 10-15k steps to just whatever bare minimum of limpy walking was required to get to work or meals or move around indoors.  Thus, for the final days of last week I was barely moving, and over the weekend, I pretty much wasn’t moving at all.

Early this year, when I started having back pain, I traced it to a similar walking fall-off, and ‘miraculously’ cured myself just by starting doing sufficient daily walking again.  But, apparently, I’m a slow learner.  Or, conversely, maybe I didn’t realize how quickly the absence of walking could be felt—especially if I’m also not pushing myself in the gym.

Indeed, by Saturday night, I got in bed, and spent several hours staring at the ceiling before I was finally able to fall asleep.  And then, on Sunday, despite being super tired all day, I again got in bed and couldn’t fall asleep, this time for pretty much the entire night, watching the time slowly tick by in fifteen minute increments until I gave up and groggily got out of bed at 5am.

By Monday, I felt terrible.  But I was also at least just smart enough to have identified potential cause and effect.  So, I got in at least 7500 steps, tweaky knee be damned.  And I made it to the gym for a short workout, easing back into light squats, presses, and deadlifts.

Monday evening, I was out cold almost before my head hit the pillow.  And then slept like a log for eight and a half hours straight.

So, if your own sleep is less stellar than you might hope, consider adding some movement into your day.  Even thirty minutes of fast walking makes a big difference for me, and that’s a small amount of time to invest for seven or eight far-more-pleasant hours of snoozing in exchange.
