That’s exactly what I am saying.
If you look at Fat/Glucose they are chains of C,H,O atoms. When we process them, almost ALL FUEL is the “Burning of Hydrogen” and exhaust of CO (For cars, for example).
For us, it is very similar, we break these down and end up with Extra CO2 and H2O as a side effect.
So we exhale the CO2, and pee out the H2O.
Also, remember that Glucose is stored with H2O to stop it from being sticky (like 3 H2O to one glucose molecule [Dr. Fung mentions this]). So, this is why we pee so much when we start getting into ketosis… It’s GENIUS of our bodies… They stored the FOOD with WATER. Let that sink in.
If you had NO FOOD and NO WATER, as your body taps your glycogen/glucose, it releases purified water, which your body can choose to keep, or pee out. If you are also dehydrated, it will keep it. Dry Fasting, BTW, is considered to raise your metabolism to gain access to this extra water! (I did not like dry fasting, I cramped up something fierce)…
But you got it. We exhale CO2 and we pee out the H2O, and that is how the WEIGHT leaves our body. You can search for a TEDX talk on the topic. He exhales, and freezes it in a bag. to show you what your exhale weighs…
