我比较喜欢清淡的口味，不爱太油腻的菜。

Wǒ bǐjiào xǐhuān qīngdàn de kǒuwèi, bú ài tài yóunì de cài.

I prefer light flavors and don't like dishes that are too greasy.

最近总吃油腻的东西，难怪长胖了。

Zuìjìn zǒng chī yóunì de dōngxi, nánguài zhǎngpàng le.

You've been eating greasy food all the time lately, no wonder you've gained weight.
