On “When somebody loses weight, where does the fat go?”
Someone on youtube made a perfect video explaining this with enough precision: not sure it's this one link to this video but close

Ruben Meerman explains the stoichiometry of weight loss and how the mass of burned fat leaves the body as carbon dioxide and water.
NOTE FROM TED: This talk only represents a stoichometric approach to understanding metabolism and weight loss. TEDx events are independently organized by volunteers. The guidelines we give TEDx organizers are described in more detail here: storage.ted.com/tedx/manuals/tedx_content_guidelines.pdf 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)Why it's here
6 people recommend thisWhat people say. Recommended for its clear, scientific explanation of how the body actually expels mass during weight loss.

On “When we lose weight, where does it go?”
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: link to this 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 " link to this video

On “Death of the Calorie (2019)”
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: link to this video

On “Scientist busts myths about how humans burn calories”
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: link to this video

On “Ask HN: Have you tried weight loss drugs?”
Whenever I have a discussion about weight loss, I like to share this TEDx video: link to this video Just because I think it is quite interesting, not trying to make a point or anything :-).

On “Losing 100 pounds in 276 days”
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! * link to this 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. link to this video

On “Ask HN: Any weird tips for weight loss?”
Here's how I lost weight: 1) Download the Lose It app 2) Buy an apple watch (or whatever matches with your phone) 3) Connect the watch up to the app 4) Fiddle about with the settings 5) Stay below the line Excercise is optional . I did this for my dad and he can barely move, and he lost like 12kg. The only reason ANYONE ever loses weight is because they consume less energy than they burn, there is no other way for energy you consume to leave your system: link to this video

…ial pressure of CO2 remains the same. There is some oxygen removed but only as much as the hemoglobin can carry. Prolonged 100% oxygen has no effect on this and is also toxic over time. People on oxygen therapy are really breathing 40%, and 100% is only used for short stints during anesthetic procedures. This video explains how weight loss occurs: link to this video…
