Provide the theme summaries for the following conversation: 

#Person1#: Sally, I'm tired of this Western food. I really miss my mother's Sichuan cooking. 
#Person2#: I'm sure you do miss that type of cooking. But can't you try to get used to Western food? 
#Person1#: I have tried. But Americans like butter, bread, sugar, and cream too much. 
#Person2#: I suppose you're right, Lee. Maybe that's why so many Westerners are overweight. 
#Person1#: It's interesting that Americans work very hard at their jobs, do not take naps during the day, and yet they can be so heavy. 
#Person2#: You see, because we are often busy working, we eat too much fast food, and that food is very fattening. 

Summary: 
Lee misses Sichuan food and Sally persuades Lee to get used to Western food. Lee cannot because the food was fattening and Sally agreed.
