It seems to me that there really is no need for something called a cheat day. This is an eating program that we follow, and not a high school test, Some days we follow the program better than others, is all.
That being said, it is not good to deliberately go astray from OMAD, unless there is a reason and you are planning for it, If it is a holiday and you know you will be having more than one meal that day, then it is something that you have planned for, and not something that you just did on the spur of the moment and for no special reason.
That is when an eating plan can become cheat days, because you are no longer even trying to follow a schedule.
