Weigh-in Wednesdays - Week 2: Elminate a Trouble Spot

Week 2 of my 14-week journey to be lighter and healthier by the end of the year. If you missed my previous posts, here are links to them:
The Anti-New Year's Resolution
Week 1: Know Your Numbers
This week only down 1/2 lb. Not great but slow, sustainable progress is the aim here. I kept a journal of my eating and exercising, and have been able to identify a few (quite a few in fact) trouble spots that I know need to be turned around. If I try to change all of them at once, I know that I'll burn out. So I am choosing just one trouble spot to work on for the month of October.
For the entire month, I am going to battle a bad habit that I've had for quite a long time: Eating at my desk. This is going to be a difficult one. If I'm in a rush in the morning, I'll often take breakfast into my office. If I'm at home at lunch time, again I tend to make a sandwich and eat while working. The reasoning has been that I'm saving time by eating and working at the same time. Unfortunately, it's now become a Pavlov's dog type of habit - go to office, bring food with.
I've read that in order to eliminate a bad habit, it's best to replace it with something else...an alternate behavior. What can I exchange for bringing food to my office? Taking my office down to where the food lives is definitely not an option. Any ideas? Well, I'll let you know what I come up with next week.
Until then, stay healthy, stay active, and stay focused.
I need to follow your lead and eat better combined with a better exercise regime. Thanks for the reminder, and best of luck for hitting your gaol.
