What to say when ppl ask why I'm not eating?

Looking for something quick that doesn't require me to explain anything about fasting or why I'm doing it. People are so nosey! I've been taking "lunch time" in my car and 2 people have mentioned that they didn't see me in the staff room 🙄; I just said yeah I went out.Thanks via /r/intermittentfasting https://ift.tt/sLSjhWk https://ift.tt/D53mc8T
