It is but it isn’t. CICO is not the whole picture, but it is the foundation of the rest of the picture.
No matter what you eat, if you consume and absorb fewer calories than you burn you will lose weight, whether it be through body fat or body muscle.
That is a known truth.
However, there are many other factors at play right now that every single person that just jumps on the calorie in calorie out bandwagon refuse to wrap their heads around.
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.
People who say CICO doesn’t work are asserting that, at no point did I assert that. I simply stated that CICO isn’t the mechanism that keto uses.

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.
