Defensive eating is strategically consuming food for the sole purpose of preventing others from getting it.
防守型吃法就是指技巧性地吃東西，只為防止他人來搶奪。

It would frighten others if you choose to lick your food or the peripheral circle of your cake first to define your manor. You could also eat the more delicious part first or pretend to frown when you eat it, belying the actual strength of your food. Only do you use those strategies to protect your food can you be a better foodie!
先在自己的食物上舔一下，就可以讓別人對你的食物望而生畏，或者吃蛋糕先吃外圍一圈，圈下自己的領地。還有可以先吃盤里最好吃的，或者吃東西的時候假裝皺眉頭不讓人知道你所吃的美食的實力，都是防守型吃法。做吃貨做到如此，美味才能獨享！

Example:
In order to prevent his friend from getting the palatable meal, Michael used defensive eating to consume his dishes.
為了不讓小伙伴吃到如此美味的飯菜，麥克用防守型吃法吃完了他的菜肴。
