8. Turn off the TV
Don’t let television dictate when you eat. In a study, Wansink and his colleagues at the Cornell Food and Brand Lab found that Parisians, who listened to internal cues (“I’m no longer hungry”), tended to have a lower body mass index than Chicagoans, who relied on external cues (“My TV show is over”). So replace the dining area television with a laptop—also great for looking up healthy recipes.
