If you go to a nutritionist for help with a diet, they'll (probably) ask you to record what you're eating now and examine it with you. Any diet for weight loss (probably) requires you to cut out "empty" calories i.e. processed food that doesn't provide real nourishment. Anything that you eat just for the sake of eating it. The same concept applies to all aspects of life! Nourish yourself with meaningful work and stimulating conversation, and stop eating emotional PopTarts (no offense intended, Kellogg's)!
