Although activeness on my Facebook in addition to Twitter accounts mightiness suggest otherwise, I’m non a large fan of social media. I participate inwards it because I experience similar I “have to,” non because I peculiarly savor it. Then again, every bit I am extremely introverted, it’s a slap-up means to interact with people without having to really interact with them. I tin unplug in addition to disengage the 2nd I start feeling uninterested, overwhelmed, or exhausted. That beingness said, 1 of the slap-up things close Twitter is that I larn to interact with some quite bright people whom I would never otherwise have got “met,” in addition to I am regularly presented with ideas that blow my mind. (That’s how I came across the materials close Dr. Kraft’s insulin assays, which inspired the insulin series.) Often, these are ideas in addition to concepts that should endure pretty obvious to me, in addition to the alone argue they aren’t is that I’ve just never stopped to think close them. And non alone are they pretty obvious, but they’re often release in that location or tweeted close casually, every bit if the author is maxim something relatively simple. H5N1 one-off postal service or a couplet of lines close something that seems similar no large bargain in addition to is a full no-brainer to them, but which, upon reflection, turns out to endure a huge bargain to me. For example: the registered nurse who goes yesteryear the online nickname “Woo” often drops noesis bombs that shipping me into a hurricane of thoughts. She holds no punches in addition to does non endure fools. Her writing manner takes some getting used to, but she is really 1 of the most intelligent in addition to insightful people currently writing close metabolism, endocrinology, calories, ketosis, fat adaptation, torso weight regulation, PCOS, in addition to lots of other things many of us are interested in. Time in addition to fourth dimension again, something she posts makes me meet things inwards a novel light. So much light, inwards fact, that she should purchase stock inwards General Electric, Phillips, or another companionship that manufactures lightbulbs, because that is how many of those things travel along over my caput when I read her work.
Case inwards point: a few days ago, Woo made the right observation that, inwards many cases, children who are position on a ketogenic diet (KD) for epilepsy tin really stop the diet after a couplet of years in addition to remain seizure gratis for life. Something close staying on a KD for some menstruation of fourth dimension during one’s formative years seems to really permanently right the underlying problem, such that the diet tin endure abandoned afterward on in addition to the seizures do non return.
Coupling this fact with some observations close people on low-carb in addition to Paleo diets, she came to some rather fascinating conclusions, in addition to proposed an observational study. First, I’ll tell you lot close the study, in addition to and then we’ll piece of work through the rationale for it, via exploring some intriguing things close torso weight, in addition to why some of us are so incredibly prone to accumulating excess adipose tissue, patch others are not.
- Children on a strict ketogenic diet for epilepsy (or another condition) who are eventually able to supply to a to a greater extent than “normal” diet in addition to remain seizure free, are protected from developing obesity afterward inwards life. (I would corporation to say nosotros would probable discovery the same final result fifty-fifty alongside kids who follow a modified Atkins diet [a.k.a. “MAD”], in addition to who were non strictly ketogenic.)
The report could endure carried out inwards 2 ways:
- A retrospective cohort. Find every bit many teenagers in addition to adults every bit possible who were on ketogenic diets every bit children, but who no longer follow a KD. Assess anthropometric parameters. (Body weight, torso fatty percentage, etc.) The older the people nosotros tin find, in addition to the longer they've been off the diet. the better.
- A prospective cohort. Enroll every bit many children every bit possible who are currently using a strict KD or MAD to care some variety of medical condition, in addition to follow them for every bit long every bit possible after they abandon the special diet. Assess anthropometric parameters. Again, the longer nosotros tin follow them through their lives, the better.
To reiterate, the hypothesis is that these kids volition remain lean into in addition to throughout adulthood, even after returning to a to a greater extent than typical, Western-style, obesity-inducing diet. They volition endure what Woo (fabulously) calls “constitutionally obesity resistant.” (I love this phrase. Being “constitutionally lean” is 1 thing, but “constitutionally obesity resistant” really hammers dwelling theater the betoken that it’s basically impossible for these people to travel fat, fifty-fifty upon exposure to the same things that brand the residue of us so.) I can’t speculate on whether they would remain gratis of the myriad other effects of the metabolic syndrome-inducing crap American diet, but it makes sense to me that, at the real least, they wouldn’t travel obese.
Here’s the logic:
As nosotros all know, in that location are people who tin swallow ungodly amounts of refined saccharify in addition to refined carb-laden junk nutrient without gaining an ounce, patch in that location are others who demand to purchase larger pants after but looking at a cupcake. What gives? Could something inwards childhood or adolescence endure “programming” us for these fates afterward on? How much does the dietary—and, therefore, hormonal—landscape of early on life influence torso weight rule throughout the residue of one’s life?
These thoughts came to Woo because of real keen observations she’s made close some prominent figures inwards the low-carb in addition to Paleo worlds. Some people tin do just fine on a diet of 100-200g of carbs a day, patch others—at to the lowest degree for the sole purpose of achieving in addition to maintaining a important fatty loss—need to rest nether 50g (or less!) forever. (Remember, inwards this post, I am referring only to weight issues. I am non talking close cognitive function, neurological health, diabetes, or another status that mightiness do goodness from a real low-carb or ketogenic diet for reasons that have got nil to do with torso weight or fatty mass. Those are split upward issues, to which this logic mightiness non apply.) To the hardcore low-carbers in addition to keto dieters out there, 150g of carbs per solar daytime mightiness audio similar a lot, but compared to the measure American diet, it’s really relatively low. (It’s 600 calories, which would endure just 30% of a 2000 calorie per solar daytime diet. Compared to a diet of 50-65% carbs, 30% is low.) If you’re inwards the habit of reading the success stories & testimonials on Mark’s Daily Apple, or Robb Wolf’s site, in addition to then you’re familiar with the see that some people tin swallow sweetness potatoes, white rice, beans, gluten-free staff of life in addition to pizza, in addition to maybe fifty-fifty have got a weekly or monthly “cheat meal” or splurge, without regaining whatsoever of the fatty they lost yesteryear going Paleo or Primal. Who are these ninjas who larn to have their cake in addition to swallow it, too have got their cake and their steak, and swallow them both?
Well, to a greater extent than often than not, these success stories—the ones where people have got far to a greater extent than carb leeway than the residue of us—seem to endure written yesteryear people whose extra weight/excess torso fatty was a temporary situation. Maybe it was the freshman fifteen, or post-baby weight, or some extra pounds that had come upward on due to real stressful life events: a divorce, a expiry inwards the family, loss of a job. These are people who were, for the most part, for most of their lives, lean. Being overweight was a blip on the radar, caused yesteryear something fairly slow to identify: lots of late-night report sessions over takeout in addition to beer; a few months of drowning one’s fears in addition to worries inwards a pint of H2O ice cream in addition to a family-size handbag of chips (crisps, for my U.K. readers). Being heavier was non these people’s default state. So, when they cleaned upward their diet—even just 80% of the time—their bodies easily returned to their naturally leaner state. Since beingness heavy was non the norm, getting dorsum to a smaller size was easy, because it’s what the torso wanted. (Maybe fifty-fifty what the torso was programmed for.) In social club to larn dorsum to a lower weight in addition to torso fatty percentage, all they had to do was take away the stimuli that were moving things away from the norm, in addition to it’s almost similar the torso automatically went back.

Never inwards my life have got I been this ridiculously happy about an apple. |
It seems that these folks, the ones who lived for many years inwards a low-insulin state—particularly if this depression insulin Earth was during the formative years, either early on childhood or maybe into in addition to throughout the teens—are almost “immune” to becoming obese. Their bodies simply won’t allow them larn there. Sure, they mightiness gain a few pounds hither in addition to in that location after some menstruation of fourth dimension of especially debaucherous eating. Maybe they’ll gain, say, ten, twenty, or at the very most, 30 pounds. But their bodies simply volition non allow them to accumulate 200, 300, 400+ pounds of excess adipose tissue. At their heaviest, these people volition never endure candidates for bariatric surgery. (Maybe they’re fifty-fifty protected against heart disease, Alzheimer’s, tinnitus, nephropathy, in addition to some of the other weather associated with caused [at to the lowest degree inwards part] yesteryear hyperinsulinemia, but again, I can’t speculate on that.)
Like the hypothesized long-term weight rule effects of children on ketogenic diets, having spent at to the lowest degree some important amount of fourth dimension inwards a depression insulin Earth may grant these people some flat of protection against amassing torso fatty every bit readily every bit other people do.
Okay. So what about those other people?
I am 1 of those other people. I am 1 of the ones who acquires an additional mentum after just walking past a bakery. I am someone nosotros mightiness telephone remember “constitutionally overweight-prone,” or, “constitutionally resistant to remaining lean.” Right now, I’m non obese. I’m non obese, but I am a far outcry from lean. (In fact, yesteryear the BMI chart, I am squarely inwards the overweight category. BMI is a terrible in addition to unreliable metric, but still.) And it is my theater contention that the alone argue I’m not obese is that I am keeping my biological propensity for the accumulation of inordinate amounts of adipose at bay via a low-carb diet. If I were to supply to a diet of 50%+ carbohydrate, in that location is no doubtfulness inwards my hear that I would endure obese. Heck, I gain weight easily fifty-fifty just getting a petty also casual with my diet now, in addition to that’s non fifty-fifty coming unopen to a “normal” flat of carb intake.
So the enquiry is, why? What is it close me—and the other people who are constitutionally overweight or obesity-prone—that differs from the people who were heavy for alone a curt menstruation of time, in addition to whose accumulation of weight was easily reversed?
Well, I can’t speak for others, but here’s what happened with me. When I human face at pictures of me from when I was a baby, in addition to upward until sometime inwards uncomplicated school, I was thin. No sign of impending weight problems. But non long after that, my parents opened an H2O ice cream store. They sold homemade H2O ice cream, candy, cakes, novelties, etc. This shop was a presence inwards my theater unit of measurement for 10 years. Every kid’s dream, right? Yes. ... If they desire to create out their weight for the residue of their life, that is.
I have got 100% responsibleness for my dietary habits during that decade. Maybe my parents could have got kept a amend optic on me, but my begetter was working 2 jobs, in addition to my woman bring upward was inwards the shop vii days a week. Ultimately, the soul who fed me all that junk nutrient was me. Maybe, at nine years old, I didn’t sympathise that I was setting the phase for metabolic consequences I would human face the residue of my life, but the ignorance of youth doesn’t absolve me of personal responsibility. So I blame no 1 but myself. Honestly, though, it doesn’t matter. It doesn’t affair how or why I’m inwards the metabolic pickle I’m inwards now. I’m inwards it, in addition to there’s no means out of it. No permanent way, anyway. (More on this inwards a minute.)
Even after the shop was a distant memory, my diet was high-carb. Not high-junk, but silent high carb. I was a major starch-a-tarian inwards high schoolhouse in addition to college. Bread, cereal, pretzels, pasta, bagels, granola—hey, starchy foods are cheap, in addition to they’re depression inwards fat! It’s the double-score for a college girl! Because I spent so many of my formative years inwards a high insulin state, I am almost the opposite of the obesity-resistant. No, non “almost.” I am the opposite. I am obesity-prone. Unlike the people who gained a few pounds inwards college, or due to a stressful in addition to unpleasant, but short-lived life situation, my body’s norm is not lean. My default Earth is chubby. While it’s (relatively) slow for the constitutionally lean to lose weight, it’s (extremely) slow for the constitutionally obesity-prone to gain weight. When a constitutionally lean soul gains weight, the torso wants to get rid of it. It wants to supply to its “happy place” of a lower weight. When a constitutionally obesity-prone soul loses weight, the torso wants to regain it. It wants to supply to its happy seat of a higher weight.
I said inwards a higher seat that there’s no permanent means to contrary my body’s proclivity toward accumulating fat. But in that location is, depending on how you lot human face at it. I tin manage my obesity-proneness via a permanent low-carb diet, relatively depression stress, expert sleep, in addition to exercise. But I cannot reverse it. I can’t travel dorsum inwards fourth dimension in addition to erase having spent most of my adolescence in addition to immature adulthood awash inwards high insulin. Those effects are permanent, or, at least, they seem to be. This is why those of us who, for whatever reasons—be it mom & dad’s H2O ice cream store, or lots of junk inwards the house, or the maternal diet/gestational diabetes exposing us to hyperinsulinemia in utero, or something else—now seem “programmed” to endure heavier, in addition to have got to create out so hard to maintain weight off in addition to endure so diligent close our diets. Yes, nosotros tin indulge hither in addition to in that location in addition to non gain dorsum fifty or a hundred pounds, but nosotros tin easily gain dorsum at to the lowest degree a few. And the truth is, if we

There’s a argue this is so damn hard! |
Those of us who were overweight or obese for a long menstruation of time—especially if this fourth dimension includes childhood—are capable of becoming lean. We tin travel lean, but nosotros volition never endure as lean, nor maintain that leanness every bit effortlessly, every bit someone who was never obese at all. I think beingness awash inwards insulin during youth is especially problematic, in addition to likely makes people especially prone toward overweight. But fifty-fifty if you lot were sparse during your formative years, if you lot were obese inwards adulthood for a long menstruation of time--decades, perhaps—then you lot volition likely struggle just every bit mightily every bit those who were heavy inwards adolescence. This is especially troubling for the youth of today, who are, as Dr. Ted Naiman says, “marinating inwards insulin inwards the womb.” These kids are inwards problem from infinitesimal one. Literally before they are fifty-fifty born, their bodies are beingness conditioned yesteryear a hyperinsulinemic environment. If you lot think the “diabesity” epidemic is bad now, just you lot wait. (Not to call cancer, Alzheimer’s, in addition to more.)
WHY is this all so difficult? WHY is it possible to “manage,” but non completely reverse the biological propensity toward accumulating excess adipose tissue?
Again, Woo, with her bright insights. (I would link to or embed her relevant tweets here, but her trace of piece of work organisation human relationship is protected, so I can’t do that. She is extremely protective of her existent life identity. My paraphrasing her in addition to giving you lot the gist volition have got to suffice.) She posted this picture:
This is a photograph of a normal-sized human standing adjacent to a human who had a increase hormone (GH)-secreting tumor before inwards life. H5N1 tumor that secretes inordinate amounts of GH prior to the closing/fusing of the epiphyseal plates volition displace the bones (especially the long bones—femur, humerus, tibia, ulna, etc.) to endure much longer in addition to larger than normal. (The epiphyseal plates are the tissues betwixt the long bones that remain soft in addition to pliant during growth, but which eventually—sometime inwards the tardily teens or real early on twenties, fuse in addition to solidify, stopping farther growth. Once your epiphyseal plates have got closed, you lot tin halt expecting your increase spurt. You’re every bit tall every bit you’re ever going to endure without lifts inwards your shoes. [I have got to admit, though, I’m 37, but at just 5’2”, I am confident my increase spurt is coming any solar daytime now!])
The betoken of this painting demonstrate is to demonstrate that some of the endocrine influences early on inwards life are irreversible. Their effects are permanent. Take the guy with the GH tumor: after doctors take away the tumor, it’s non similar this guy is going to shrink back to a normal size. He is huge in addition to volition always endure huge. You tin have got away the excess increase hormone, but he volition still be 8 feet tall. He volition still have enormous hands in addition to a real deep voice. You can’t brand those things travel away. You take away the tumor, in addition to the pathology is arrested (meaning, he's non going to larn even taller), but the effects of that pathology are non reversible. This guy cannot endure “cured” of his excessive tallness simply because nosotros have got removed the stimulus that made him tall. In the same regard, nosotros tin take away chronic hyperinsulinemia, but that does non automatically brand us insulin-sensitive. It doesn't magically "undo" all those years of elevated insulin. The constitutionally obesity-prone cannot endure cured of this propensity. We tin alone swallow in addition to alive inwards such a means that nosotros don’t trigger the effects. (And if you’re planning to have got children, or you lot have got immature children already, you lot tin do your best to forbid them from having this propensity inwards the outset place. That’s probably the best seat to start.)
I’ll paraphrase some of Woo’s tweets, since I can’t portion them with you lot directly:
- Even though the insulin reducing protocol acts exactly similar tumor surgeries inwards other endocrine diseases (in that it arrests the pathology), CICO-phants are also dense to sympathise in addition to acknowledge the efficacy of low-carb diets in addition to other insulin-reducing measures.
- When nosotros meet this phenomenon inwards obesity, ignoramuses think this is testify that insulin must non displace obesity because low-carb diets are non a “cure.”
- Insulin does non simply alteration fuel work acutely, in addition to drive increase or shrinkage of the adipocyte (fat cell). Insulin is to fatty tissue every bit increase hormone is to the residue of the body. (Meaning, some of the effects volition endure permanent, especially if the chronically elevated insulin was acquaint for a long menstruation of time, in addition to fifty-fifty to a greater extent than so if it was acquaint during the formative years.) Therefore, fifty-fifty if you lot perform the obesity equivalent of a GH tumor removal surgical physical care for yesteryear putting someone on a diet to lower insulin, it’s silent non a “cure.”
- Depending on the nature of the problem—at what betoken inwards life did obesity develop, in addition to for how long was it present—maybe an “ancestral” diet works. On the other hand, maybe non fifty-fifty a keto diet does. Meaning, for people who were alone a petty overweight, in addition to maybe alone for a few years, an “ancestral” diet plant similar magic. Beans, fruit, non-gluten grains, potatoes – it’s all good! No weight regain, no metabolic syndrome, no nothin’. But for others, who were real overweight for a longer menstruation of time, maybe non fifty-fifty a low-carb diet works. Maybe non fifty-fifty a ketogenic diet works! (Not yesteryear itself, anyway.) Maybe those people demand a ketogenic diet plus fasting, plus exercise, plus metformin, plus, plus, plus. And it is these people—the ones who struggle the most—who volition be struggling their entire lives.
Then again, it depends on what nosotros hateful yesteryear “struggle,” right? Certainly, eating delicious pork chops, steaks, broccoli, Brussels sprouts, in addition to cheese, isn’t just “struggling,” right? (“First World problems,” every bit they say.) And maybe beingness “forced” to larn sufficient sleep, care stress levels, in addition to engage inwards physical activeness to a greater extent than than the average soul for the sole sake of preventing fatty regain isn’t much of a struggle, either. But you lot know what I’m trying to say: the lifelong battle to forbid fatty regain mightiness non endure a hero’s bespeak worthy of Greek mythology, but for the people who are constitutionally overweight- or obesity-prone, it is a lifelong battle. We volition never endure able to swallow every bit casually or without see to protein/fat/carbs every bit those who are constitutionally obesity-resistant.
Wow. So that was the [very] long means of offering at to the lowest degree 1 explanation for why some people do just fine on higher carbs, in addition to others don’t. And also why, for many people, a low-carb diet, by itself, is non plenty to lose weight in addition to maintain that loss. (Also: just so we’re clear, when I verbalise close “higher carbs” in addition to an “ancestral diet” every bit opposed to low-carb or ketogenic diets, I’m non talking close loads in addition to loads of sugary breakfast cereals, toaster pastries, in addition to other outright garbage. I’m talking close unprocessed, real foods, such every bit rice, potatoes, beets, in addition to lentils, which are wholesome in addition to nutritious foods that have got nourished salubrious in addition to robust populations for centuries, but which just travel on to endure high-ish inwards carbohydrate. The people I referred to inwards the success stories on MDA in addition to Robb Wolf’s site—the ones who thrive on 80/20—sure, sometimes, maybe they do a header into a tub of gelato, or hitting upward their favorite BBQ articulation for some brownish sugar-smothered ribs in addition to a big, honkin’ slice of cornbread, but fifty-fifty they don’t do that every day. Now in addition to then, yes. And they tin larn away with it, for reasons discussed hither today. For the most part, though, their “higher carbs” silent come upward from existent foods.)
That’s all. Just a petty to a greater extent than nuance to explicate why people are so dissimilar with honour to weight gain, loss, in addition to maintenance.
P.S. I am so tempted to call names – to say just who I hateful when I referred to some of the well-known figures inwards the low-carb, Paleo, in addition to ancestral nutrition worlds, in addition to how some of them volition never travel effortlessly slim, patch others volition never travel obese. Some of the heavier folks volition larn slimmER than they are naturally, but they volition create out molar in addition to smash every solar daytime to stay that way. And some of the constitutionally lean may position on a few pounds in 1 lawsuit inwards a while, but those pounds volition slide off easily with non much to a greater extent than endeavour than a couplet sprinting sessions in addition to dropping the kokosnoot sugar-filled “Paleo treats.” Alas, I volition non call names. Not my style. I avoid confrontation in addition to arguing every bit much every bit possible. (Most of you lot know who I’m talking close anyway. :P) I do wish, however, that they were to a greater extent than careful non to extrapolate from their ain personal experiences to everyone else. Guess what? If you lot were never overweight, or were alone slightly overweight for a relatively curt menstruation of time, YOU DO NOT UNDERSTAND the metabolic challenges of someone who was overweight or morbidly obese for many years. And vice-versa: if you lot have got battled weight for most of your life, you lot likely have got a hard fourth dimension agreement that in that location are, inwards fact, people who tin swallow beans, potatoes, bananas, in addition to rice, in addition to remain lean. All I know is, the closed-minded in addition to angry rhetoric on both sides is getting uglier every day. I promise to remain truthful to the tagline at the overstep of my blog: “A origin of sanity inwards the bounding main of nutritional madness.”
