At the moment, I am keeping an orange and Kashi bar in my purse. I eat that around 'brunch' time and then lunch isn't so big of a deal.
Don't get me wrong, I still eat lunch, but it's not as hard to be satisfied with whatever I chose to eat.
It's cold weather, so I'm eating a lot of soup at the moment. A huge can of the chicken pot pie soup (yes, I love it) is only about 200 calories, and after my earlier snack it fills me up nicely.
For the time being it's working for me. Of course, I'll change up when that starts getting boring . .
