dr. megan jones, a psychologist from stanford university. welcome. >> thank you for having me. >> thank you for being here. doctor, how can the way you think and talk about yourself affect what you eat? >> how you think and talk about yourself has a huge impact on so if you think in a positive way about your body and about food, then that will take you towards healthy eating behaviors. >> okay. are there "red flag" words we should stay away from, even in our own thinking? >> absolutely. red flags are words like "good" or "bad," or even "healthy" and "unhealthy." so words that mean extremes, that are black and white. so when we have rigid rules about food, that sets us up to have less enjoyment in our eating. >> and that enjoyment can also mean less healthy eating? >> absolutely. unhealthy in terms of fighting with food or feeling like you're guilty if you eat the wrong thing. there's no wrong thing to eat. it's just how much you have of it. >> well, i guess we should change the old saying "you are what you eat" to "you are what you think." >
