This is such an obnoxious form of pedantry. Yes you absorb less calories from the food you digest and yes you poop out more unused calories and yes the way your body uses fat is less chemically efficient than carbs.
That’s just not what anyone means when they say CO.
Technically true in such an “ummm aktshully I’m a teenager that just learned thermo 101 and have to be right about everything” kind of way that’s just not relevant to the discussion being had.
Yes, of course if you put everyone doing keto in a chamber where you measured emitted heat and put all their poop through a calorimeter thermodynamics applies.
The point is none of that matters in the context of discussing diets because you can very successfully lose weight on keto while eating more calories than you did before and not changing lifestyle.
It literally is though.
When you are in ketosis your CO increases, so even if your CI stays the same you will now be operating at a deficit
It is not.
