Researchers Find Children 'Burn So Much Energy, They're Like a Difference Species' (bbc.co.uk) 63

A study of 6,400 people "from eight days old up to age 95, in 29 countries," finds that the human metabolism "peaks at the age of one, is stable from 20 to 60 and then inexorably declines," writes the BBC.

Long-time Slashdot reader Hope Thelps shares their report: The study, published in the journal Science, found four phases of metabolic life:

- birth to age one, when the metabolism shifts from being the same as the mother's to a lifetime high 50% above that of adults

- a gentle slowdown until the age of 20, with no spike during all the changes of puberty

- no change at all between the ages of 20 and 60

- a permanent decline, with yearly falls that, by 90, leave metabolism 26% lower than in mid-life

"The most surprising thing for me," one of the researchers tells the BBC, "is there is no change throughout adulthood — if you are experiencing mid-life spread you can no longer blame it on a declining metabolic rate."

Science magazine's headline? "Little kids burn so much energy, they're like a different species, study finds." [T]he first comprehensive study of energy use over the human life span has quantified their burn rate: Infants between the ages of 9 and 15 months expend a stunning 50% more energy in 1 day than adults do, adjusted for body size. These wee dynamos consume and use up energy even faster than pregnant women and teenage boys, most likely to fuel their energetically expensive brains and organs. "Little people are not burning energy like small adults," says Duke University evolutionary biologist Herman Pontzer, who led the new analysis of data from around the world. "They are burning energy superfast ... like a different species."

    When people are fat it's because of their metabolism, not because they're shoving whatever they can find down their gullet while sitting on their fat asses all day looking at their phone.

    This is one of those fake studies. I know it is because I did my own research on the internets.

    • What it says is that metabolic changes as people age don't account or weight gain. People's metabolisms still have an effect and their ability to gain or lose weight. No matter how much I eat I top out around 270. I wouldn't even minor amount of exercise and watching my diet I top out at 220. I know plenty of people who the only way they can keep from ballooning to over 300 is with ruthless dieting and exercise.

      You are close to their level of idiocy, but not quite. You also need to point out how this finding is "racist", "sexist", and how BMI is a racist lie.

      It always cracks me up how the Fat Acceptance Movement tries to glom onto other more popular or more legitimate movements to back up their insane nonsense. Their favorite is to pretend all non-white people have completely different bodies so that means BMI and all fat stigma are racist.

      It's more like some people literally poop out about half of the calories they consume and some people don't. But the hunger drive "assumes" they do.

      Thus the reports of people getting their intestinal microbiome altered effortlessly losing dozens of pounds without even an intention of doing so.

    • I’ve often jokingly said that kids have the exact same amount of energy as adults, its just that kids are moving a fraction of the mass, making them seem like a bottomless well of rambunctious behavior. If you correlate this against lazy teenage years (during final growth spurts) it starts to make a lot of sense..

  • Not like a different species, but just like humans. I assume they were studying humans, anyway. The data was on humans. I don't see how they can conclude that data on humans indicates the humans are not humans. They are obviously humans, unless there is some bizarre heisenbergish schrodinger thing going on that says that a human can spontaneously change into another species when its metabolism is measured.

    Far more likely is that the researchers are bad at communicating and could not cough up "We thought we

  • Man, my mind. Is. Blown. I mean, dude. Different species? I personally blame our racist, sexist, imperialist, patriarchal medical system for not realizing this decades ago and forcing my kids to go to an adult doctor instead of a physician that specializes in children. Seriously, I don't even know what you'd call that.
  • but it's been known for ages that kids need to eat about the same as an adult. It's not hard to understand why either, they're growing.

    I have (or rather had, they're out of college now) a kid , but in terms of feeding them I generally just bought the food and didn't think much of it, but when it was pointed out to me how much kids need to eat it kind of shocked me. I always thought in terms of kids been cheaper to feed than adults because they're smaller.

      Then why are the meals on kids's menus at restaurants always smaller-portioned?

  • Of course, children are constantly growing, that's where energy goes, hence higher metabolism. I know whenever every year or two that I get off my fat behind and start exercising some of the energy is going into growing muscle, instead of straight into the gut. It doesn't compare to child gaining an inch in height that year though. And where as an adult like myself has to dedicated hours out of a day for exercise (which I can only keep up for a few month out of year reasonably), that kind of growth (energy

    Fucking seriously? How about linking sources that are real?

    The actual study I had to click through to. PDF. [pnas.org] A 2014 study DOES NOT EVEN REMOTELY APPROACH THE CLAIMS IN THE TITLE OR IN THE BBC ARTICLE. I clicked through to find out to what extent changes in metabolism caused by diet and lifestyle changes are addressed. lolnope. It doesn't make any claim that could require that to be addressed. It's about the brain's metabolism and nothing else. I so look forward to three weeks of clickbait based on this garbage science journalism. Please, tell me more about how hunger and weight retention don't change and fuck all the fatties. I'm looking forward to that and the other side which will completely fail to address any science and use social-justice-based emotional reasoning to say "no that's wrong".
    • Given that you say yourself that the study you link to doesn't match up with the account in the BBC article, why do you say that that's the study they're talking about?

      The science article does provide that link but specifically notes that it is to a different study (from back in 2014...):

      "The growing brain is likely the key energy sucker in little kids, says biological anthropologist Chris Kuzawa of Northwestern University. Kuzawa did not participate in this study, but in 2014 his team found that the brains

  • One of the more interesting findings in this study was that there can be up to like a 25% delta between people of the same apparent build, height, etc.. in terms of metabolism. My guess (too lazy to read through the thing) is that e.g. 95% of people fall within a few percent of each other, and 5% of them vary much more greatly.

    Based on how Twitter, Reddit, etc.. work this will turn into a mythology that fat people aren't fat for any reason but it's because all of them, that what, 40%?, of the country are ju

  • And yet so many of our children are already obese by the time they reach puberty. I believe this has consequences for the rest of their lives. All 12 year olds should normally be exactly on-weight, maybe even a little bit shy of the normal weight.
  • Metabolism rate in warm-blooded animals is largely a function of size, due to surface area / volume ratio.

    People generally get fat because they consume more calories than they burn. It's long been known that this occurs due to hunger regulation, not metabolic rate.

    This "study" is trivial.
