How do genes cause kids to grow taller?

As a commenter pointed out in response to one of my previous posts, height is mostly genetic.

This is especially true for kids who grow up in the same country and the same socioeconomic level, because such a cohort largely shares the same diet and same medical care. So the difference in their height is mostly genes.

However, I suspect that an important way that genes impact height is in how genes impact kids’ appetites. As I previously mentioned, my two nephews are very picky eaters, they hardly eat anything, I rarely see them eating anything with a lot of protein in it, and they are short.

I also have a cousin who is just a little bit younger than my nephews, and she is very tall for her age. She has an appetite. She eats anything you put in front of her. She’s not fat, just tall. Her father (my first cousin) is pretty tall too, but it seems to me that the way that tallness was passed down was through a propensity to have a good appetite. (And maybe, because her parents live in New Jersey and not Manhattan, she eats more protein and fat-rich prole foods, and less of the high-carb low-protein stuff that SWPLs feed their children.)

Therefore, I believe that even though, statistically, height is mostly genetic, there can be a lot of impact from environmental intervention.

  2. Sure, just look at the first generation Chinese and Koreans. These chaps are much taller then their parents because they eat good American food. This is very simple.

    • taller but not higher IQ than their counterparts in china and korea? if so then the nutrition theory of the flynn effect has to be abandoned. of course the dutch famine is also dispositive. the flynn effect is not caused by changes in diet.

  3. As long as bare minimum nutritional requirements are met it’s genetics that makes the difference. Have you ever seen inner city black kids? They grow up eating Captain Crunch and Kool Aid for breakfast, lunch and dinner and they are HUGE. Take a look at how ripped a 12 year old black boy is, or how developed a 12 year old black girl is compared to a suburban white kid of similar age. No amount of food can compensate for the natural growth hormones, muscle fiber and testosterone present within African DNA. Similarly, a Nordic from Sweden or Denmark will always be taller than a Greek or Italian unless they are starving to death. It’s all in the genes.

    • Whites are taller on average than blacks. I think blacks just develop physically faster than whites.

      not too late

      • Much like women, blacks get more visible muscularity at higher body fat percentages.

        White Male 15% body fat – Average
        Black Male: 15% body fat – Cut

        White Male 10% body fat – Cut
        Black M: 10% body fat – Ripped

  4. Off topic but relevant here:

    Big First Amendment Win today:
    The USPTO (where I work but not on Trademarks) was told they can’t block trademarks they don’t like. It was an 8-0 decision.

    The Redskins will certainly get their trademark back.

    To be very clear, the risk to free speech comes not from the government but from private companies such as Facebook.

    The court’s Jewish lawyers (Ginsburg, Breyer and Kagan) who create the liberal consensus there are all strongly pro-free-speech. Between them and the conservatives, free speech is safe at the court for a long time to come.

    In America, most of the risk to free speech comes from basically four private companies now: Google (which controls its search engine and YouTube), Facebook, Twitter and Apple (which controls a lot of content through its store). All are basically monopolies.

    Blogs should not be under threat since they can migrate from provider to provider.

    Another indirect risk to free speech comes from orgs like the SPLC which believes in bankrupting dissenting voices through lawfare.

  5. It all comes back to genes. Some people respond well to certain diets, which is genetic. Of course, there might be a correlation between having biological parents who will feed you a lot of carbs if given half the chance and being short. There might also be a correlation between being that little bit iconoclastic and rejecting the low fat, high carb diet, and being taller.

    The fact is that no one really knows what, if anything, “works”. There’s no evidence, outside of genuine vitamin,mineral and calorie deficiencies, that feeding your kids a certain way will make them taller (healthier, smarter…) The growth in children’s height started stalling in the 70s and 80s as the low fat diet took hold, but that’s also when the demographics started shifting.

  6. “Therefore, I believe that even though, statistically, height is mostly genetic, there can be a lot of impact from environmental intervention.”

    BMI is just as heritable as height (0.8). Both have a 0 shared environment component. Both have changed over time in the population. Environmental intervention is not as easy as it sounds.

    • you and lion might want to scan a 2008 study i found last night. 161 intro psych students at UT San Antonio (open admissions) were administered a battery of 4 subtests from the WAIS + the wonderlic + the RPM.

      the g-loading of the SAT and ACT were both > 0.90.

      given that UT San Antonio is open admissions i expect the high end was under-represented relative to the general population. and it was the new SAT not the old.

      the bottom line is: the old SAT (and the new) was/is an IQ test, and a very good IQ test, probably the best. so is the ACT.

  7. In my city, I’m noticing that the 18 year old whites, male and female, are about 2 inches taller than you would expect (I am average height and about 15 years older). My suspicion is that we are seeing the effects of the sexual revolution where women are more free to reproduce with taller men. Also, I suspect that many kids are being given human growth hormone (prescribed or black market).

    • There is a canard that centers around tall people inheriting all kinds of social advantages, especially when it comes to attracting women. Women prefer men who are average, with 5’11” as the most desirable height. I could only imagine anyone taller than that would feel a little off and uncomfortable, especially when it come to 8′ ceiling apartments that are so common in Manhattan.

      • Yes, and that’s probably analogous to shorter women who are usually more attractive (also more sexually voluptuous) than taller women, when it comes to physical attractiveness. It’s like your IQ and state school theory. People from upper tier schools are generally more attractive than those from the Ivy Leagues.

  8. SWPL’s also send their kids to artificially stressful prep schools with a heavy emphasis on forced memorization and calculation far beyond the point of meaningful learning. They’re probably forced to sit down for 10 hours a day, when you include the obligatory piles of homework. The benign neglect of proles is much healthier for children. Sure enough, you see proles reproduce more and their children just seem happier than the high powered striver yuppies.

  9. Keeping eating eggs everybody, keep eating eggs. Eat at least 4 eggs per day. Don’t worry about the cholesterol. Cholesterol is good for you, much of the brain is made of cholesterol. Besides the lipid theory of heart disease has not been validated, despite 50 years of researchers trying to make the connection. Eggs are nature’s perfect food.

    Full disclosure. I own a significant number of shares in Cal Maine (CALM) the largest egg producer in the USA. Buy Cal Maine stock too. It is selling cheaply now. Eggs will never go out fashion, Cal Maine will never go out of business. Is run by the same Mississippi cracker family who founded the company in the 1950s.

  10. Millions of years of evolution ensure the vast majority of people will eat and eat and eat. Now that food is abundant, we have problems with obesity. Anyway, when it comes to height, environment matters, which is why not all that long ago, height correlated with consumption. Today, as others have pointed out, genes are the determining factor because most people meet their basic nutritional goals.

    • Diet is only half of it. Childhood diseases are hard on a growing body and stunt ones growth. Better sanitation ad vaccinations probably have as much to do with increased height as food.

  11. Tall kids with strong appetites feel hungry because their body really is hungry for the nutrients to build their body the way their genes programmed it to do. Activity will also cause an increase in appetite. When my son was young, small and skinny and short, I put him on a weight improvement program where I sat him down and made him eat two cookies and a glass of milk or a meal every two hours. He gained weight and height and eventually developed a better appetite. He was always a good eater and not pick per se, but he would fill up on vegetables like broccoli and green beans which have no calories and then be too full to eat higher calorie foods. He is athletic, played four years of varsity sports in high school. But he did need encouragement to eat more calories when he was little.

    • Her thesis about White people being the apex of human civilization, where this originated from Christianity doesn’t take HBD into consideration.

      Before Christianity, there was Stoicism, which shares certain similarities of rationality and foregoing material lust, and this mode of thought came from Ancient Greece.

      Furthermore, Muslims in their Golden Age (those who were Persians) surpassed East Asians, when it came to scientific and cultural output. It must be in the genes.

      • Christianity, or at least European culture, of which Christianity was an integral part in the relevant period, probably promoted eugenic breeding. cf. Greg Clark.

        Islam, meanwhile, seems to have encouraged dysgenic breeding and inbreeding. In particular, contrast the success of Christians in the Middle East with Muslims. Apparently the evidence is that today’s Christian Arabs are much closer genetically to Classical/early Medieval Middle Eastern populations than Muslim Arabs are — they escaped the worst of those dysgenic processes.

      • Sorry that you asked a shitty question, Gmette.
        I don’t pretend to be an organic chemist but I understand well enough that DNA nucleotides are used as a template to build proteins, which is the primary building block of every cell in your body, the catalyst of chemical reactions, and the tool by which other substances are transported through the body. But my understanding here is simply the DNA serves as a the linear blueprint. In reality, proteins are not just linear strings of chemicals but are folded in complex three dimensional structures whose shape determines how they are chemically capable of bonding to other substances. My chemistry is too rusty to really understand precisely how all of that works at that level.

  16. Sure. It’s worth remembering that logically there are lots of things your body could do, even as an adult, with extra food other than just building fat. What if your body turned that extra nutrient to making you feel more energetic? Or routed it to your brain for sharper thinking and more creativity? Insofar as we can figure out to tell the body to do that, that’s really the killer app for health and weight loss.

  18. Kids are pretty stupid, lazy and whimpy compared to when I was growing up. A bunch of babies. Who cares what they eat? What goes into their brains is what’s important. They need to go bootcamp, or at least this is what I think.

    I was working by a realy rich customer yesterday, I mean real rich, for real I mean. Now she’s got these two teenage sons, you know. So these bums just sit around on the couch like some vegetables, damn it! So she goes: ‘ Michael, if you are doing nothing, now is a good time to do your two pages of math.’ And she is Jewish! Jews are getting stupid too now. What’s gonna be with all these veggies? I should’ve told the kid to go read ‘The Sea Wolf’. I hate stupid rich Jews.
