Lose weight the slow and incredibly difficult way

There are different ways to measure calories. In a calorimeter you can measure all the calories in some stuff. In your body the amount of calories available to your body to digest is some amount less depending on what that stuff is. This can vary from foodstuff to foodstuff by (iirc) about 1-15%

So one could be more accurate and say Available CaloriesICO I guess

Unless you are an athlete or have some condition the simple CICO rule is accurate enough to be useful. Eat less, move more, and weight will be lost (or at least gains will slow).

None of this says anything about each person’s own life challenges that alter how difficult it is to do that.

I think that the energy density of rocket fuel is pretty easy to measure. If you're trying to do a food powered rocket it's true the energy measurements could get more complicated.

Now that you mention it, I'm pretty sure modern calorimeters won't catch the energy available via nuclear reactions. What if our digestive tracts have evolved some as-of-yet undiscovered mechanism to tap into that energy, thereby invalidating all the "CICO" people's claims? Now that would be a real pickle.

Wouldnt the undigested calories just get added into calories out?
