I have been on the FODMAPS diet for about 4 months and started a new job with no comments from anyone. I work close with people in confined spaces and not a word as of yet. The only slip up I had was drinking too much juice the other day (too much of the allowable fruits can start a problem) and the next day was bad. No one said anything at work but I could smell it on myself.
I have only lost about 5 lbs from the diet and it's pretty varied if you stick to the list. E-mail me if you want more info. Good luck, hope this helps your problem.
