Are you really hungry? Or are you anxious? Often I start munching when I’m stressed and on deadline. If that’s the case, popping a piece of gum or getting myself a cup of tea often helps. Or perhaps it’s time to stretch or take a short walk to get some water. An exercise break is even better. Personally, I’d rather take a timeout to walk than to eat (which again I think I can do while working), as I usually return to my desk with improved focus. Of course, this takes convincing myself that it’s OK to go for a walk during the workday and probably good for productivity.
