Here is a healthy and filling snack that will keep you away from the vending machine when hunger strikes. I keep a container of sunflower seed spread at my desk and spread it over fresh celery. You could also try dipping carrots.
And yes, that is a dumbbell in the background. I keep a five pound hand weight at my desk and give my arms a little workout whenever I’m on a break/on hold etc. Gotta sprinkle that activity in anywhere you can get it, especially when sitting in a cubicle all day!
