I didn't have any trouble staying in shape at my previous corporate job. Although the sitting around all day was really bad, it wasn't too hard to get into a daily routine that included 2 hours in the gym. Diet was only a problem until I found a place nearby that sold huge subs for $3, for whenever I didn't prepare my own lunch.

Sickness (eg influenza), alcohol, and lost sleep have had a far greater impact than work of any kind. YMMV though, I've never been overweight in my life and have never been a heavy/frequent drinker. Ultimately I think it depends on how you manage time and whether you prioritize exercise and diet.
