I travel a lot for my job too and had to learn how to survive. It’s really hard when I go out with clients and don’t drink and barely eat!! When out to dinner with a group I always order something that has grilled chicken I can eat. Last week I ordered chicken fajitas and just opened the tortilla and ate the chicken. Also, every time I get to a new city I’ll Uber to a cvs or grocery store and get a box of protein bars. I do the Atkins snack bars when in a pinch. I’ve also learned that restaurants can be really accommodating! If you need to sub in a veggie for a starch most of them are happy to do it! My favorite trick? I have a client contact who likes to DRINK! And he makes it really uncomfortable for anyone who doesn’t. In this situation I’ve learned to volunteer to order the drinks and ask the bar tender to give me iced tea served in a high ball glass... my boss finally figured me out but no one else! Hope this helps! Being the only one on a strict diet can suck, hang in there!
