Little fires aren’t happening all up in our bodies…are they?
In: Biology
You almost literally burn it.
Your body (usually) converts the calories you consume into a sugar called glucose. Far, carbs, sugar, alcohol, protein, all things that have calories, all turned into glucose.
Your cells then burn glucose to do all the things that keep you alive. Move muscles, make new cells, grow, think. All burning glucose.
Now surely I mean “burn” metaphorically, right? Well, yes and no. There’s no a flame, that is a very hot plasma. But it’s basically fire, a much more controlled one. Consider that rust is just iron burning, “fire” can be slower and more controlled. The sugar your body burns does the exact same thing sugar does if you lit it on fire, oxygen is consumed, and it turns into smoke. Smoke being water vapour and CO2. That’s what you exhale, CO2 and water vapour. You exhale smoke.
