And if I remember from a nutritionist who posted here, the way we lose weight is by breathing CO2 out.
Food is extracted for its nutrients in our digestive tract and excreted. Yet the way we lose weight is by breathing.
(I cannot find the source of that claim)

- jdblair 8y agoAll you're talking about is metabolism and respiration. All metabolism oxidizes fuel (broadly speaking, fats and sugars) and generates C02. Excluding anaerobic metabolism, which only happens in times of heavy exercise or hypoxia, all metabolism results in C02.
- mr_toad 8y agohttps://en.m.wikipedia.org/wiki/Cellular_respiration https://en.m.wikipedia.org/wiki/Cellular_respiration It’s technically true that we (animals) can convert fat into CO2 and water. But we burn this fat to release energy. If we don’t need this energy (if we consume more calories than we burn), the fat just accumulates.
- smsm42 8y agoYes, this is true - and if you think about it, can't be any different way, really. I mean, where else would it go? No chemical reaction can destroy any noticeable amount of mass. Excretions - like peeing and pooping - don't carry out too much mass too. So how else you'd get rid of some mass?
