> The human body is way more complex than CICO
The human body is way more complex so as to defy the laws of physics as we know it? The human body cannot create matter. In order for it to increase in mass, you must be inserting extra mass into it.
Note that none of the known laws of physics say that excess energy is saved by converting (which raw materials?) into fat and storing them.
