I've stopped munching at work most of the time, and try to grab an orange or some yogurt when I do get hungry instead of reaching for chocolate or chips. I've also been drinking more water, but that started because I had gradually gotten so dehydrated that my sinuses were killing me and my eyes were always dry. I have an exercise bike, but I haven't ridden it in far too long.
The comments seem to have started right after I applied for that opening in day shift accounting. I suspect it's a confidence thing rather than any actual weight loss, like the Viagra ads where the guy's coworkers think it's everything else instead. I've been a lot more relaxed and comfortable with myself lately, a great deal happier overall, with my physical body a lot more integrated into my self-concept than it once was. There's still "me" (mind/spirit) and "it" (body) - but they overlap and merge now more often than not.
No word yet on the job front, by the way. They brought in an A/R specialist from another hotel to straighten out the mess that had been left behind, now (so I've heard) they'll decide whether and how to redefine the job duties before they make any other decisions. I've been told this could take several weeks, so I'm trying to be patient. And even if I'm not the person they're looking for for that job, I've lost nothing and gained much just by trying.
