The "CICO diet" most here are referring to is when people attempt to estimate their "calories in" and their "calories out" and keep the former slightly lower than the latter. To my knowledge this has not been demonstrated to be generally effective, possibly due to the challenges with estimating these values with a reasonable degree of accuracy. If you're simply referring to the physics of CICO that underpin most diets then I have already acknowledged it is correct. But being correct does not make it necessary knowledge for people looking to lose weight any more than Hamiltonian mechanics is necessary knowledge to play tennis. If I still haven't managed to convey the distinction between technical correctness and practical utility yet then I have to conclude this is a gap I cannot bridge and I wish you luck.
