Yes Calories Do Count but not as CICO (Calories In Calories Out) 
Calories and Macros are counted for their Quality, Attributes and Ratios for the induction of Ketosis, control of Insulin, preservation and building of lean body mass, and to utilize fat as the primary fuel source in order to establish an environment conducive to healing and optimal Health
