Author of Big Fat Myths. Teaching people that food is made of carbon which we exhale as CO₂. EAT LESS, MOVE MORE means "eat less carbon atoms than you exhale"

Where does the "C" in exhaled CO₂ come from? This gaping black hole in health literacy feeds the weight loss industry and keeps the fads coming. My @TEDx talk explains the biochemistry and why we need to start teaching it in primary school invidious.fdn.fr/nM-ySWyID9o

Music to my eyes! Looking forward to hearing about all your atomic adventures 🤓

This is the best Twitter question ever🤓 Some ideas: Classify magnetic V non-magnetic metals (ferromagnetic to be precise) Your science dept might have iron, nickel, cobalt (magnetic) + aluminium, copper, bismuth or others to test. Silver, gold jewellery also👍 1/4

Mr Ian (aka @AtomicSchools) does magnesium ribbon + vinegar in test tube with 7 year olds. Reaction fizzes because it makes hydrogen gas. Teacher ignites gas in🧪for students. It goes "pop", kids go🤩🥳🤔. Copper doesn't react with vinegar, nor does silver, gold... 2/4

A teacher demo for 7 year olds: Burn steel wool Place ~15g steel wool on digital scales (accurate to 0.1g) and record weight. Burn steel wool, outside, on an aluminium pie tray or similar. Weigh burnt steel wool again. It’s heavier😱 Where does the extra mass come from? 3/4

Teacher demo for 7 year olds: Melt gallium in your hand Borrow some gallium from your science department or buy on eBay (it's cheap). Non-toxic but best as a demo. Pour into moulds eg Lego figures. It melts in your hand, warm water (do it in a glass bowl or tiny aquarium)

Music to my eyes 🤓 So rewarding to see the children so eager to continue learning about atoms and molecules. Thank you for sharing Carly and @BangkokPatana School!

So good!
Lyra has loved frogs, bugs and spiders since she was very young. But after starting school, she'd come home saying girls shouldn't like those things. So What The Duck host @jones_ann went on a mission to prove that #girlsDOlikespiders. ab.co/3K3PdPc @petrialadgrove
Thank you Daniel, great to get this sort of feedback from the coaching world 🙏
Shout out to @surfnscientist for being a phenomenal educator and articulating a widely misunderstood concept in such a succinct way. Running coaches pay attention. "Eat less, move more and keep breathing" invidious.fdn.fr/vuIlsN32WaE

Music to my eyes @sporthackdave. And nice infographic @tednaiman! You can't argue with "carbon in, carbon out"

Thank you for the kind words @MediciseA
@surfnscientist thank you for this brilliant video! This should be shown to each human being! Great work sir!👌 Watch this video if you are interested in your health. How breathing and metabolism are interconnected | Ruben Meerman | TEDxBu... invidious.fdn.fr/nM-ySWyID9o via @YouTube

Dear anatomists and medical people, I took this thermal image of my feet and discovered my left middle toe is significantly warmer than my right middle toe. Why? Different vasculature/circulation? Is this asymmetry common in feet? Many thanks in advance!

The most rewarding thing about showing kids cool science experiments is hearing from those kids more than a decade later to tell you they’re a scientist now 💙🥲 Thank you @QLD_ScienceWeek, made my day 🤓
I loved watching @surfnscientist and Backyard Science growing up on @ABCTV and now we've also got Scope and Get Clever @Channel10AU @Channel7 to teach a whole new generation about #STEM with a whole new set of #science hosts @Constababble @stcoakley @IllJayGee plus more to come!

Hey, scientists! Check this out 👇👇👇
We're doing a #TwitterTakeover for #NationalScienceWeek and we're looking for willing #scientists to take over our Twitter page for a full 24 hrs to talk fun science and answer questions! If you're interested send us a DM! @DoctorKarl @surfnscientist @ScienceSteve1 @a_romilio

'Science education has failed' Excellent opinion piece by @JustinDillonUoE and @lucyavraamidou... I could not agree more
#COVID19 has shown people aren’t prepared for societal challenges of the future: it’s time to put science and environment literacy at the heart of #scied, say @JustinDillonUoE and @lucyavraamidou edu.rsc.org/opinion/science-…

Music to my eyes! Breathe out more carbon atoms than you eat back in and you are guaranteed to lose weight. Keep breathing 🤓
@surfnscientist Dear Ruben, You convinced me that THIS IS THE METHOD to stay in shape and to stay healthy. I've watched all your videos and I understand the principle. 3 Kgs in 2 weeks, eating normal, moving more and breathing!

You're very welcome Árpád... my original @TEDxQUT talk went into more detail about how to calculate those percentages. If you're interested, I'd recommend reading about "doubly-labelled water" (²H₂¹⁸O) studies. Ingenious, fascinating science invidious.fdn.fr/vuIlsN32WaE

LIVE WEBCAST with @Ed_Harrold: A conversation about fat metabolism and the direct physiological connection between breathing and weight loss. It's going to be fascinating! 🇺🇸3:00pm 21 April (MST) 🇦🇺7:00am 22 April (AEST) RSVP: edharrold.com/events/how-the…

We know ⅔ of oxygen atoms in fat becomes CO₂ and ⅓ becomes H₂O because: A) CO₂ + H₂O ⇌ H₂CO₃ ⇌ HCO₃⁻ + H⁺ B) stable isotope studies with ¹⁸O by Lifson et al Skepticism is👍so any more questions, just ask 🤓 Here's the link: jbc.org/article/S0021-9258(1…

I agree, it is not simple. In fact, I made a mistake in my original @bmj_latest manuscript, as you'll see in the published errata. Try using a spreadsheet instead of a calculator so you can trace your errors through: bmj.com/content/349/bmj.g725…
