1. Worth watching : The fundamental of losing weight
    Before letting capitalism fools you.

  2. As a physicist, I liked many parts of the presentation, but I have lost
    more kg than him while eating the same or more, and doing no exercise
    whatsoever, which is enough to doubt his claims. And obviously he knows
    very little about serious weight loss research, which clearly shows again
    and again that weight is mainly controlled by hormones and that eating less
    and exercising more only works for a small percentage of the population,
    and it is a complete failure for everyone else. I guess we physicist like
    to simply things too much.

  3. Here is an interesting review of basic chemistry.
    I like to remind people around me that trees are made of air ( Where Do
    Trees Get Their Mass From? ).
    Now I get to be reminded of how pervasive the carbon cycle is, and how
    important breathing is.

    If anyone has a good pointer to the biochemistry of fat decomposition,
    please post in comments.
    For all I know, this talk does not preclude the existence of a “make you
    slim pill”, by inducing the decomposition by means other than “hunger or

  4. Just to clarify, science does not teach you can convert atoms into energy,
    that’s total bull and anybody who learnt a bit of chemistry knows that.
    What they are saying is that the process to break down that fat, in the
    end, produces energy. Get your facts right and don’t blame schools for
    human stupidity. 

  5. That was a complete waste of time! I know that they can figure out how
    many calories you burn by you breathing. That is the most accurate way to
    tell how many calories you burn. This is so stupid It was a special on the
    local news years ago. I am just stupefied by this

  6. i think at the end he meant low carbohydrate diets, not low protein, since
    he was talking about ketosis which has nothing to do with protein.

  7. but you actually CAN turn mass into energy, there was this guy like a
    century ago that prooved it, a guy by the name of Albert…. Einstein…
    you know e=mc2 means “energy” equals “mass” time “speed of light
    squared”… so you can turn mass into energy and energy into mass, that´s
    how nuclear plants work.

  8. Finally, someone has looked under the hood. It seems when we have a less
    than educated population the gurus win out over the thinkers, e.g. economic
    philosophers compete better than monetarists. Nice to have mathematics
    introduced into the discourse.
    Again, great video, great presentation, let’s hear it for using that thing
    on top of our shoulders. Good Job!

  9. When you lose weight, where does it go? This is a very basic question, with
    a seemingly obvious answer….watch and find out!

  10. This is the best Ted talk I’ve ever seen and the best science demo I’ve
    ever seen. I think all kids should see it, but first.. you adults.

  11. I know this may sound crazy but… Could you trigger the hormone to start
    breaking down fat molecules with your mind? You can trigger other hormones
    like adrenaline. Instead of imagining a threat you could somehow induce the
    feeling of hunger perhaps?

  12. GAAAAAAAAAAAAAAAHHHHHHHHHHHHHHHHHHHHHHHHHHHH!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
    That number is NOT the weight of a single carbon atom nor will it ever be.
    That number is the >>>>>MASS!!!!!!!!!!! < <<<< ( I have a personal vendetta against "weight" ) of 602,214,130,000,000,000,000,000 carbon atoms. A.K.A. a mol of them. Avagodro's number, it is kind of a big deal and if you are going to talk chemistry, know chemistry first >:(

  13. Hmm… Are most of the people in his country white or did he only ask that
    question to white people? Either way I think in school I was told that fat
    cells never leave your body but shrink. Interesting topic tho!

  14. I like the general idea of his presentation. We’re now learning that weight
    loss isn’t all just about a “one size fits all” way of life. Some people
    have hormonal imbalances that prevents the body from burning fat as it is
    supposed to. I’m an aspiring dietitian and nutritionist and I would never
    do the job of a physicist and it makes me feel a little weird having a
    physicist talk about weight loss. It is cool to think of the atomic
    structure of fat, but it’s really only effective when talking about how the
    body breaks it down and how genetics and hormonal imbalances have an impact
    on those processes.

    Here’s my perspective on obesity (I’m generalizing a bit): Carbohydrates
    are converted into sugars. If they’re not used, those sugars are stored in
    fat cells. The USDA recommends that we eat 300 grams of carbohydrates a
    day. That’s an insane amount. Why on earth would the USDA recommend that
    many carbohydrates per day when those that develop diabetes and other
    metabolic issues are then told to eat under 100 grams per day (a lot of
    people I know with diabetes are actually told to eat about 50 grams of
    carbs per day)?
