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