9. You're basically inhaling your food
Not all messages travel as fast as email: leptin and other hormones that send the message of "you ate just enough, and if you keep eating you will probably get fat" need time to work. All those wise sayings, like "chew your food 20 times" or "wait 20 minutes for seconds" -- ones that seem to have come from a time when people didn’t have anything to do -- were essentially getting at this simple fact.
10. You're caving to peer pressure
"Well, if you insist, of course I'll help you eat those sweet potato fries!" Kapur explains that meal composition and timing have a lot to do with how hungry you are throughout the day, both of which can be thrown off by eating with company. Of course, you don't want to be so inflexible that you become an antisocial health freak, but it's worth thinking about your personal health goals and how your body tends to work -- and whether you like your coworker enough to screw with the balance.
Bottom line: hunger's not always real
"Hunger is a very relative term," Kapur cautions. "You want to ask yourself, is it legitimate hunger?" She suggests considering the points above for context, and particularly thinking about when you last ate, what it was, and whether you’re hydrated. "If you consciously think about these key things, your hunger will start getting regulated," she says. "About 70% of the time, it's probably not hunger."
