I have a work event coming up and not sure if I’ll eat, or keep to my fast. I think it would be a shame to break it.
Was thinking of saying, well I’m fasting and if I eat this food I’ll have explosive diarrhea.
I don’t think anyone would say anything to that
… and It’s not entirely a lie lol
I guess learning to avoid social events you do not want to attend for any reason is very important in general. That is not different for coworkers. I would just make something up, your girlfriend is sick, you have an upset stomach, you do not like them, whatever.
They do not need to know if you do not want them to.
