為健康或減重而控制飲食
把「平常怎麼吃」變成「刻意管控怎麼吃」：當你決定只吃某些食物、少吃一點，把日常飲食框進一套規則裡，diet 就從「你吃什麼」窄化成「為了減重或健康而定的飲食計畫」。
diet, weight-loss plan · noun · B1
A plan of eating only certain foods, often to lose weight or to get healthier.
節食
核心畫面
Picture the food a person or animal actually lives on day after day — what regularly goes on the plate. That everyday pattern of eating is the core of diet; only later does the word narrow to a special plan to eat less.

可以想成：一個人或一隻動物日復一日實際靠著吃的東西——每天固定端上桌的那些食物。這種「平常怎麼吃」的模式才是 diet 的核心；「為了減重而少吃」的計畫反而是後來收窄出來的意思。From the word’s history
From Greek 'diaita' meaning way of life, regimen — how you live day to day. Food is the part of that way of life that stuck to the word, so 'diet' first means the eating pattern you live by, and only afterwards a plan to control it.
源自希臘文 diaita，原意是「生活方式、日常作息」——你每天怎麼過。後來這個字保留下來的，主要是生活裡「吃」的那一塊，所以 diet 先指你賴以維生的飲食模式，之後才衍生出「刻意控制它」的計畫。
etymonline.com/word/diet; Wikipedia 'Diet (assembly)' (Greek diaita 'way of living, regimen'; the assembly sense split off via Medieval Latin dieta associated with Latin dies 'day')
From the picture
一味餵給人的某種東西
把「每天固定吃的東西」當比喻：如果一直反覆餵給人的不是食物，而是某種活動或內容，也可以叫 diet。就像天天只吃同一道菜會膩，天天只有這種東西也讓人受不了。
a diet of, too much of something · noun · B1
A diet of something means too much of an activity that you think is boring or bad for people.
一味的（某活動）
