口痕搵嘢食

口痕搵嘢食（英文：grazing ^{[註 1]}），或者叫口痕摷嘢食，係一種食嘢相關嘅人類行為規律。如果話一個人口痕搵嘢食，意思係指呢個人重複又冇計劃噉走去搵嘢食，次次都只係少量噉食，而且明明唔覺餓都走去搵。口痕搵嘢食可以係一種唔想做都忍唔住去做嘅行為^[1]，個人好多時食咗之後會感到內疚等嘅負面感受，因而為個人造成心理壓力^[2]。

啲人口痕搵嘢食嗰陣，特別傾向去食一啲細細哋一件件、唔使點樣花費精神就可以食得嘅零食。例如想像而家有個人喺櫃入邊收埋咗啲曲奇餅。佢喺屋企無所事事就會想去開櫃攞曲奇餅嚟食（重複），每次都淨係食一塊咁少（少量），每塊曲奇餅唔使花咩工夫準備，會為佢帶嚟小小嘅快感。

問題

呢種行為就噉睇好似冇咩大不了，但係一個人每次口痕搵嘢食都可以搞到佢一日多咗 200 至 300 卡路里。每日食兩三次已經會積少成多，多咗 600 至 900 卡路里—普通嘅成年女人每日需要 2000 卡路里左右，而普通嘅成年男人每日就需要 2500 卡路里左右^[3]，即係話一個人習慣咗口痕搵嘢食，分分鐘（喺卡路里攝取上）等同每日食多咗一餐咁滯。

事實係，健康方面嘅研究睇過啲一度減肥成功但後尾肥返嘅人，發現佢哋之所以會肥返，其中一個主因就係因為佢哋有口痕搵嘢食嘅習慣^[4]。
