The mathematics of weight loss | Ruben Meerman | TEDxQUT (edited version) 

Be careful, education reform might one day lead to a well informed electorate.

Good thing I’m a kid at school:)

STEM subjects are definitely a lot more interesting as a kid when it's applied to something practical.

fyi, they do teach this in schools (at least in australia) Source: am in year 10 and had more or less knew everything in this video. But yes, there should be more emphasis placed on more practical skills such as this.

I learnt this is biology...

Hahahhaha

😂🤣

😂🤣😂

I was going to just start blowing up a bunch of balloons every day until he said that lol

I was doing it too, until I read your comment. Lol

lol agreed

If you're in ANY allied healthcare degree in college it's - BIOCHEMISTRY!

Knew it turned into co2 and h20 but not the percentages! That’s so cool!

Same for me, he made it fun

Then go and watch breaking bad

Outrageous

Is actually that simple.

well eat more (healthy foods), move more, keep breathing is more efficient

Meat only, move and mindfulness works for me

@@jmcglifting453 that's healthy which difference aspect of weight loss

u will lose ur mind and all the muscle/lean mass u have,, eat less but nutrition dense food, so that u lose weight healthily

I'll wait too see if achieve your task

It’s a lot easier than people make it sound

@@kpeezy776 you dont need any gym equipment to lose weight. 90% of this is better nutrition. You just need to eat less calories than you burn. Most people fall into the trap of adding exercise, but also consuming more food (because the body has established a "normal" rate of excess calories each day and that's how your appetite works. Your appetite will trick you. It is not telling you what the body needs. It's telling you what you normally do. And since you are looking to make a change (new healthier weight and lifestyle) you have to ignore your appetite and choose a good macro nutrient profile. Adding exercise helps of course, but ultimately you want to eat approx 100-150 calories less than you burn (you BMR + any exercise). Counting calories can be a bit tiring and tricky, but once your body adjusts to being a little hungry, you no longer associate that feeling with hunger, but with wellness, with not consuming excess.

i don't know where your husband and you are in your journey, but if you met your goals, congrats, and if not, here's a friendly reminder to not give up! consistency really is the key

So sad that is absolutely oversimplified and not really true...

Which part isn't true?

+Dean Graves the part where all the food you eat is use for energy and or stored . A lot of the food you eat is used to repair and replace cells in the body. research done by ali crum proofed that just by modifying what a person believed ,has an effect on weight loss and or metabolic action ... eat less move more fail.

Nico, here's an easier simplification of what he said. If your body can't use everything you've put into it, the excess is stored or excreted. Too much energy in versus energy used = overweight. Thus, move more, eat fewer KJ or calories, make yourself cold while maintaining KJ/calories, etc. It really is that easy. He isn't comparing raw energy intake between individuals (i.e. fast vs slow metabolism); only in a particular case, if weight is a problem, just eat less, or move, or both.

+ualaelinlive I understand what he said ... the problem comes in when you understand that the process the determines energy yield(calories ) of food and what happens to food in your body is vastly different second to that food you eat doesn't only provide energy most of it is used to repair and replace cells in your body. Thirdly ali crum's research strongly suggest that by altering only a set of believes weight loss will occur . At 4:57 he actually says that little arrow there is a 3 year degree ... No how much would you trust a doctor that's 3 years short on his degree? Now when you eat your metabolism speeds up and when you don't eat it slows down so you must be referring to basal metabolic rates and that has nothing to do with having a weight problem .

us aussies like showing off the fact we can acomplish almost anything on ya standard outdoor BBQ camping table

Didn’t know there was such a standard for tables.

Sarah Kozak.....Your comment made me laugh way too hard! 🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣

NO.

The table used to be bigger, but it lost weight.

Fascinating and sometimes unfair 😂

Having the same activity level doesn't mean using the same amount of energy. If you eat the same amount and burn the same number of calories it will be equal.

It depends what you mean by the same amount of food. Many people confuse calorie deficit with calorie requirements. Calorie requirement is the thing that varies greatly depending on your body including size and hormones, but every person will change by a specific amount with a specific deficit

Wait… this is so crazy because I was wondering the same thing. Every time I’ve lost weight, my breath always seemed weird. I know people talk about “keto breath” as well.

It's a very superficial amount of chemistry in the video.

I'm old...we never had chemistry in grade school or middle school & if it was offered in high school....I failed to notice. Or maybe it was my lack of math skills...only one year required, so it wasn't offered to me 🤔

And then he said that in order to lose weight, you should eat less and move more, which is a useless oversimplification of the task at hand. In other words, it's interesting for the science, but it's useless for weight loss.

Yes and constantly lowering your calorie intake will cause your metabolism to slow down too so your weight loss will come to an end and leave you with a slow metabolism. You will still be overweight and will put on weight eating less than when you started

@@gordonpaulsen7359 i dont think a lower calorie intake will slow your metabolism. perhaps if u lose a lotta muscle mass then ur body's consumption of energy also goes down. so that's when muscle-training and high protein food (to increase muscle mass) will be beneficial to weight loss

@@gordonpaulsen7359 The speed of the metabolism is not directly linked to your calorie intake. It is a factor, but a VERY minor one. Something that Slimming World, Weight Watchers and these kinds of ridiculous diet programs have abused and exaggerated for their own success, and to the detriment of their customers. Weight loss does simply not just come to an end by reducing your calories, so I'd highly (and respectfully) recommend doing some more reading on this before making statements to your friends such as this one, as they only do more harm.

@@markwillis1045 I have done research on this topic and believe my comment is correct. If you're interested, listen to Dr Jason Fung's talks on fasting vs reducing calories

You would think a PhD biochemist could spell bowels.

It's not that people have lost faith in science, it's science that has lost faith in itself. Climate Change research is driving this trend more than anything. It is a pre-determined conclusion to which data and hypotheses are made to fit, because if they don't YOU GET NO GRANT MONEY. There is $0 of funding available from any major source for research that leads to a conclusion contrary to the 'consensus'. This is terrifying. The whole point of the scientific method is that consensus can always be wrong in light of new information and understanding. This has happened on many notable occasions, where the research of one individual rewrote and wiped out the supposed laws of entire fields that had stood as fact for, in some cases, thousands of years. Heliocentrism and Plate Tectonics are two towering examples. I just worry that 500 years from now, people will read scientific history books and snicker at our time and say "Wow, they believed people could actually affect an entire planetary climactic system, primitive idiots. They probably thought the Earth was flat, too, hahahahahah....oh wait, polls from that time showed the majority of people under 35 DID believe the planet was flat." Above all, science, more than any discipline, needs to keep an open mind free of presupposition.

Robert Morgan I know we need to start getting that flat Earth funding going , am I right? Moron.

Bobsmithgeorgette, talking about education and the world being a better place, even though I doubt that Donald Trump would understand the mathematics he might enjoy the visual effects and maybe take in a little bit of it. And then he would go and say: 'I told you, global warming is fake news!!'

If you want science teachers like him, PAY THEM BETTER. And give them plenty of administrative support (including getting rid of useless "assessments" of "skills"); replace that edubabble with SUBJECT MATTER.

Robert, the hole world is not like the US, in my country our government pays for a lot of the scientific work, not private companies. We do not need to come up with results showing that "this is not harmfull". Best regards from a swedish scientist. :)

Everything is the sun. Do some more reading on quantum physics and how it plays into biology. We SEE due to photons. We are powered by the sun ,but it's processed by the body. It's where melanin comes into play. Read about how mitochondria in the cells work. The earth evolved with the sun. All life upon the earth is connected with the sun. Fittingly, eventually, the sun will go nova and destroy all life on earth. What it giveth, it will take away.

Except that he clearly doesn't understand ketosis, and there are many other scholars to argue that it's much more than eat less move more 🙄

Health Wise You have to be specific as to whom is making you laugh out loud. We are needy people.

It’s not that the concept is difficult to understand. People understand it. The difficult part is putting it into practice. There isn’t one single reason people are overweight or obese. People are triggered by so many things and food has become their vice. By no means am I saying that is an excuse to live an unhealthy lifestyle. I’m saying that unless one knows a person’s story and knows what they’ve been through people shouldn’t judge. Many obese people are judged to be lazy and gluttonous. It may be true for some but others have tried to lose weight. Life deals them a blow and they derail. Other times the body actually works against them.We all have vices and things we are addicted to. This world would be a better place if there was less judgmental people. I’m not saying you’re judgmental by your comment I’m just saying people in general.

People enjoy eating. It's a fact of life.

ep·i·dem·ic a widespread occurrence of an infectious disease in a community at a particular time. So...we should stay in our homes, so we dont catch it? Exaggeration is a disease, by your usage.

@@longdong982 so obesity is a widespread lifestyle disease and prone to infect others, or an epidemic as you yourself defined. One can catch it through neglect and some thought patterns (memes) can be used to spread it. Thus, it isn't that crazy to quarantine yourself from other people (both in real life and in virtual life) or things that will make you more likely to become obese. RU-vid search "This videa will make you angry" which explains this better than I can.

Bernardino Franque exactly

I've watched qute some Ted Talks in my Young life, but this comes so late.

This may sound like a conspiracy theory... All this 'new' information, particularly about diet and medicine, has been hushed up by the food industry (can you imagine the problems caused if the public stated demanding that HFCS and sugar be removed form the foods we eat), the pharmacological industry, and the weight loss industry for years. The drug companies have no interest in you learning how to live without their drugs. That's why we haven't seen a disease CURED in almost 50 years. There's no money in curing a disease, but plenty in 'managing' it... Why sell one pill that stops the disease, when you can sell a lifetime of pills to extend that person's life? And who funds most medical research, and medical training facilities, and offers fantastic incentives to doctors to prescribe, prescribe, prescribe? The 'weight loss' industry is worth BILLIONS a year. A lot of that heads back to the treasury as taxes, so government has a strong incentive to 'leave sleeping dogs lie' (and paying tax)... The food industry has lobby groups whose specific task is to ensure the government does nothing to alert people the wool being pulled over our eyes. I am now seeing more and more videos, TED talks and promotional videos basically trying to take down all these barriers to 'truth'. A film-maker in Australia made a controversial film regarding high sugar diets. It was pointing out some really interesting information. The Australia Medical Association had the film pulled off Netflix as 'misleading and dangerous'... What they didn't say was that it was dangerous to the incomes of the drug companies who support the medical industry... As I said, sounds like a conspiracy theory to me, but remember, a few 'conspiracy theories' have actually been proven to actually be the truth... So, 'please consider'...

@@RicardoPerez-st7pg AND BREATHE!

It makes me hungry just to think about eating less... another Ted Talk for another day.

What about the idea that some foods take longer to digest than other foods? Does this make it quicker to loose weight with foods that digest faster, ie. Fruits, vegetables, or juicing? Do certain foods turn to carbon dioxide and water, quicker than other foods?

@@RicardoPerez-st7pg eat less move more. Bahaha. Good luck with that

Eat healthy, don't just count calories. It's a lot more to being healthie than calories in and out. This Ted talk is is plain bs when you don't take any notice of human metabolism an fysiologi. You can harm yourself even while eating no more calories than you need and get a lot of illness as reward of being mislead even though it's seems to be convenient learning all you need to now in a few minutes.

@@blfalken His math is wrong.

Also give it ample time to work its magic. Some (Including me) expect the weight loss to happen right away after making changes and it doesnt, it takes time, but the more steady you allow yourself to lose, the more steady your weight will stay over time. If you crash diet and lose fast, the weight usually doesnt stay off.

Except you fail the two compartment problem, and the hormonal problem. Calories in vs calories out fails over 90 percent of the time, now either 90 percent of overweight people are lazy good for nothing slobs, or we are not taking into account the two compartment problem and the issue of hormone driven hunger/satiation.

@@TwoPlusTwoEqualsFive32 This is where macro ratios come into play. There is no magic in the % of proteins, carbs, and fats that you eat when it comes to weight loss. It doesn't matter. Calories are all that matter. But your macros DO matter in your satiety and energy level. You COULD lose weight eating 1200 Kcal of cookies each day and nothing else. Problem is you will feel like junk and be starving and quit the diet in 2 days. Eating more protein and fats helps you feel full and satisfied, as well as energetic while you cut your calories. I have found that 16/8 intermittent fasting is a GREAT tool for cutting calories. If I don't eat until noon each day, and not after 8:00 - it becomes MUCH easier to regulate my calories into lower daily totals. Exercise ALSO helps regulate hunger and cravings. Break a sweat everyday for 30 min (or longer if you can!) and eat in an 8 hour window with .8 - 1g of protein per lb of lean mass on your body per day. You WILL see results week by week. (Plus - sugar is an addictive substance just like a drug so get that out of your life and body and that is a difference maker.)

That’s a horrible idea

He didn't. He skipped it by calling it biochemistry. He actually went out of his way to call what he discussed year 10 chemistry, but okay.

No, he discussed 20 minutes of it.

No that's not solely respiration that's to do with diffusion / osmosis to a cellular membrane AK the lung air interface. It's got nothing to do with the respiration part. Respiration part produces the water. The vapour part happens in lung due to things to do with relative humidity and temperature differentials but I won't bore you with that

don't eat them and exercise :)

I noticed that too. I think he meant low carb.

uhm maybe vegan..?

Yes, he should have said low carb or high protein when referring to ketoacidosis. Slip of the tongue I assume.

No, keto is a low-protein diet as well, I think he was commenting on how low-protein diets aren't a great idea because they can cause depression. The fact that keto is low-carb is a given already in that context.

Ditto

Wow, that could actually be a helpful tip for anyone doing something like that! I would have never thought of that.

Sorry but drinking water does NOT provide oxygen for breathing. You're unclear on the physiology. In order to make breathing easier, there are only 2 ways - more oxygen IN THE AIR, or less activity (need for oxygen). Drinking or eating food or drink that contains oxygen thinking it's going to help with high altitude breathing is woo.

@@spocksvulcanbrain Acetazolamide helps as well

If I’m not mistaken, the problem with altitude (hypoxemia) has to do with the fact that overbreathing to help make up for less oxygen at higher elevation also effects blood acid-base balance by making the blood too alkaline (low CO2). The kidneys try to compensate for this by the excretion of bicarbonate ions (a base) in the urine. The drug “Diamox” (acetazolamide), a renal carbonic anhydrase inhibitor) mimics this process, by aiding in the excretion of bicarbonate ions, thereby allowing greater hyperventilation and more oxygenation. The primary trigger for breathing (respiratory drive) is not the lack of oxygen but the abundance of carbon dioxide. Carbon dioxide in the blood stream is in equilibrium with carbonic acid. If we breathe off too much CO2, that partially extinguishes our reflex to breathe. The kidney’s effort to compensate for this to acidify our blood stream allows us to breathe more. This is why exposure to higher altitude causes a well-hydrated individual to diurese (pee more).

The water helps because of the low humidity. You're constantly losing water to the air. The last thing you want is to be dehydrated and hypoxic. Water affects the former not the latter.

likewise

It's odd that he said that after making the point so strongly that we don't actually turn our weight into energy, well then we don't turn energy (sunlight) into our body weight either.

@@bxdanny Yeah that was one of the dumbest things he said. The living things on the planet gain low(er) entropy energy from the sun, and emit high entropy energy (heat), so it's basically about maintaining a 'workable' level of entropy with the help of the sun.

@@bxdanny he didn't mean it like that though. He said that just to be cute. Techincally we are eating sunlight somewhat kinda since it is what plants use to bind stuff with.

The energy we consume through our food is in the molecules, but not in the mass of the atoms therein, but between the lines: It is the indeed the energy that keeps these atoms tied together and gets liberated and exchanged when atoms swap places during the chemical processes of digestion and metabolism. Matter is but the (necessary and handy) packaging for energy, so in that sense it is absolutely correct to say that the energy in our food is equivalent to sunlight.

He meant that we are fuelled by sunlight, and the molecules and atoms are merely carriers of this energy.
