Everyone in my office has noticed and most have commented on my weight loss. Therefore, they make comments like, "she is being so good, that's all she is eating" or "no wonder she is losing weight, she only eats soup and no fried stuff." I talk about working out 5-6 days a week and journaling my meals (calories) so they seem to take it at that. I have 8 co-workers and only 3 know because the others talk way too much and tell their business and anybody else's they know. A lady in our work system, not our office, had gastric bypass and I commented about her having lost so much weight and one of those "talkative" co-workers stated, "oh, she had gastric bypass." I had no idea, but knew I would never tell her anything personal. I don't know if that lady wanted everyone to know.
Most of us bring our lunch and/or go get it and bring it back to the office to eat, so we are at a table together. When I do go out to eat with co-workers, it is almost always only the ones (3) that know. I only eat out with the other 5 is for a special occasion.
