This is the edited version of The Mathematics of Weight Loss presented by Ruben Meerman. In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)

Very good. I truly enjoyed that.

Interesting lecture, but I'd just like to translate for my English-speaking friends; the word at 8:12 is aLmond.

Does he mean low carb diets at the end?

So it took 20min to say Breathe more? Lol great vid by the way. Fascinated by this stuff. I do believe most fitness trainers teach this but just in a parallel way. The same is “calories in calories out. The difference is him breaking it down literally to the molecular structure of calories in and out in addition to being active. Great speaker. This definitely should be taught in schools. Especially a collaborative effort upon the PE and Chemistry classes.

Very cute presentation but wrong - dangerously wrong. His conclusion at the end that all you have to do to lose weight is to eat less, move more and keep breathing. He threats the human organism is if it were best understood with simple physics. In fact that fallacy is the reason weight loss is so hard, Everyone tries that prescription and everyone fails. All diets work - for a while and then all diets fail. He gives the impression that he has something important to say but he has nothing.

we know people have to eat less and move more, but nobody wants to do that. obesity at this point is an addiction to food and a mental health issue too. Sad

This is a simplistic talk. It's not necessarily true that if you start moving more you will lose weight, and there is a dynamic between diet and exercise that cannot be captured by colored test tube experiments. For me and probably most people, it requires a lot of willpower to work out and eat appropriately. I think most people have problems with the psychology of addiction, rather than understanding "move more eat less."

I watched this a couple years ago, and it stayed on my mind so long that I came back in 2019 to watch it again. Great talk.

God, I hate the way he speaks. Worst accent ever!!!
James Hafford (3 days ago)
At 20:15 he mentions "low-protein diets" in reference to keto diets. Did he mean "low carb diets"?
Adam Pajcz (3 days ago)
He misspoke at the end by mentioning eating low protein instead of saying Ketosis is brought on by eating higher levels of protein.

this isnt amazing knowledge though, everybody who came here probably thought he would do some crazy chemistry lol, fact is humans are lazy and we looking for other methods besides moving more and eating less. because in todays world everything is literally about moving less, and eating more, you literally have apps to deliver food to your house. lol humans are just lazy man

Getting food into you is not “digestion,” it is “absorption” that follows digestion.

question.... If you do exercise in a cold place (sea or snow) do you lose more weight for the time spent doing the exercise as appose to doing it in a warmer climate?
Pabloottawa P (4 days ago)
OK, so eat less, move more and keep breathing. One of the issues I run into is energy depletion which occurs if i don’t EAT. So when I work out I feel weak, slow and I get that feeling that we all have when we say “dragged myself to the gym”. Sometimes it literally feels this way. So how do you maintain the energy levels to work out or move more, eat less? This is my dilemma and I’m wondering what people think. Case in point. If I eat 2 scrambled eggs with 2 strips of bacon and finish the meal 30 minutes before a run or a work out I feel better and stronger going in, my runs are more pleasant and I feel great during my work out of run. Is there a recommended eating schedule other than eat small portions and eat lean meals?

What he has not told: When you eat less, your metabolism slows down and burn less calories. You have to reduce food a lot. I lost 60 pounds in two months by eating nothing or just one meal a day.

HIIT cardio! Moving more, increasing heart rate, breathing more, keeping hard earned muscle!
Osvath97 (5 days ago)
I get that he is not an expert on ketosis but... Neither am I. What he said about ketosis was so wrong. 1. It is literally impossible for a normal human being to get ketoacidosis (not counting weird anomalies). You have to either have type 1 diabetes or a very severe case of type 2 diabetes. 2. Ketosis has been linked far more to COMBATTING depression rather than the opposite. 3. You get ketosis via a low carbohydrate diet, not a low protein diet (all though the dosage of proteins is important in a ketogenic diet in some way I do not know).

Why go to school when Tedx Talks teach you more in 21 minutes than 12 years will?
darlon ripley (5 days ago)
Except....he is dead wrong. Eat less? 1. Body senses less food inside; body conserves what's left, using less. 2. Body gets colder, tells head stop moving body so much. Mind gets sluggish. 3. Body increases craving, wanting, looking for food. Craving constant, never leaving. 4. Body fighting mind over food intake? Body wins in almost everybody. 5. Think drug addiction: Very few, once addicted, can be cured. 6. All are addicted to food. 7. Think of thin-as-rails girls wearing coats in summer. Successful losers, but thinking impaired-or just crazy. Also their bodies start breaking down. Not healthy. 8. Think of models eating then forcing themselves to throw up. 9. I can hardly wait for a Ted talk on committing suicide: Just stop breathing. 10. Goes thru the chemistry, bunch of glassware on table. Ignores the obvious.

You said no one got it right...the one bloke said you exhale it and he was right... ;)
Tony Mannucci (5 days ago)
Lots of details in the middle I didn't need, but yes, this is the message! Great message. The one thing missing is the psychological aspect. Weight loss is a psychological battle. Your body and mind resist it. So, you need tricks to help you get it done.
Nii P. (5 days ago)
It's easy to say: "Eat less", but more important is, how to not get hungry all the time, and especially, if you "move more"!

jean claude (7 days ago)
One of the worst bits of advice I've ever heard on the subject. Eat whatever you want and there will be no consequences? I'm sorry, but it doesn't take a genius to figure out that doesn't work. The only way I've been able to control my weight is by carefully calculating calories, macro's, and cooking for myself. Not only have I made amazing progress, but I feel good too that's a key benefit. So join my program... Jkjk. All I'm saying is be careful who you take advice from there are a lot of people that benefit from you being in the dark. And that bit about low protein diets leading to depression.... Deplorable. The only way I could afford to eat healthy is by lowering my protein intake and cutting out supplements entirely and I feel fine. That is all.

Brilliant. Great teacher
I think he meant to say 'low carbohydrate diet' instead of 'low protein diet' toward the end

This is all true, but it is looking at the issue with only one eye (on the 'physics' of carbohydrates). He only mentioned that it was a complicated metabolic process, and the other eye must look at the almost inconceivably complicated (and only partly understood) processes of diet and physiology that requires your diet to include the constituents of all of the tens or hundreds of thousands of chemicals needed for those complicated physiological processes, or the 'simple' physics won't work properly. That is why you need a 'complete' diet even while you are trying to restrict your caloric intake and increase your caloric output. It is good, but not easy, to keep both eyes open.

You can only go in Ketoacidosis if you're diabetic. A person that produces insulin normally will have their body create the proper amount of ketone bodies so that doesn't happen.
