About this video

Ruben Meerman presents a TEDx talk on the stoichiometry of weight loss, showing with lab demonstrations where fat goes when it is lost. He argues that most of it is exhaled as carbon dioxide.

Someone on youtube made a perfect video explaining this with enough precision: not sure it's this one [VIDEO] but close

There is a nice Ted talk about the same topic. Something I often link to people saying "I can eat everything I want in this diet..." The mathematics of weight loss | Ruben Meerman | TEDxQUT: [VIDEO] My personal weight-loss (and now sports) is largely based on understanding how the human body works with metabolism.. carbs, fat, protein.. nice and geeky

For the science geeks, here's a great TEDx demonstration with lab experiments: "The mathematics of weight loss " [VIDEO]

Your description above is not how the body works. To support a mass M must require a quantity of energy E obtained from food. The attempt to alter this model with “loose” ideas about “burn rates” therefore does not make sense. The mathematics of weight loss is laid out clearly in 20 minutes here: [VIDEO]

Fat stores are considered, metabolically, as stored energy as they expand and diminish based on the metabolizable energy of the diet, which may be different from the measured total energy. But you’re definitely right! There’s a great Mr. Wizard-style TEDx video about it: [VIDEO]

Whenever I have a discussion about weight loss, I like to share this TEDx video: [VIDEO] Just because I think it is quite interesting, not trying to make a point or anything :-).

Really great data! Thank you for sharing. The hard part for me is mindset and willpower. Unfortunately, knowing the physics* behind weight loss doesn't make it any easier, and perhaps might make it more stressful. Why can't I do this simple thing that logically is as complex as 2+2. Our minds have their own prerogatives. I wonder then what did you tell yourself? How many times did you have a bad day? What was your mood like throughout? I'd love to know so much more about the psychology. Great article though and thanks again for sharing! * [VIDEO]

I agree that cooking is a form of digestion, but that is not what I was thinking when I made my comment. We are walking tubes. The cavity inside of the tube is still external to the tube itself. This is a video that partially explains the concept. [VIDEO]
