When You Lose Weight, Where Does It Go? The Answer May Surprise You
- asafira 10y agoThis is funny: "It Gets Converted to Energy (So wrong. Law of Conservation of Mass)" Anyone other physicists around? =)
- sajid 10y agoIt's correct, mass is conserved in chemical reactions. The energy doesn't come from converting mass, it comes from rearranging atoms in molecules (which releases chemical energy).
- lippel82 10y agowell, to be very technical about it, when you release energy in a chemical reaction, you DO lose a tiny amount of mass, according to E=mc^2. However, the change in mass is very small in a chemical reaction, as the energy released is very small in comparison to the total energy of the system (given by E=mc^2).
- sajid 10y agoOk, I should have said that matter is conserved, because that's what the author is really talking about (even though he also calls it mass). In any case, mass can't be converted to energy either because mass already is energy (that's what e = mc^2 means).
- k__ 10y agoTL;DR your body produces energy by converting the "weight" to CO2 and you breath it out.
- kahrkunne 10y agoWhat a terrible article. Clickbait title, super obvious answer that everybody should've learned in middle school, some nontruths (some mass does get converted to energy. It's a negligible amount (as E=mc^2 and c is big) but it's definitely not "so wrong")

- CodeWriter23 10y agoIf you don't poop it out, why were my poops 2-3x as voluminous when I was on a weight loss regime?
