What does fasted mean?
"Fasted" is the past tense of the verb "to fast", meaning to have deliberately gone without food — and sometimes drink — for a set period. People fast for many reasons: religious observance such as Ramadan or Lent, health and dietary practices like intermittent fasting, or medical necessity, since accurate blood tests and certain procedures require an empty stomach. The word almost always appears with context about duration or purpose — someone may have "fasted overnight", "fasted for three days", or "fasted before surgery". Its noun relative, "fasting" (or simply "a fast"), describes the ongoing practice rather than the completed act. The word carries connotations of discipline, self-denial, and devotion, and its cultural reach is remarkably wide: the everyday English word "breakfast" exists precisely because one breaks a fast with the day's first meal. Simple but loaded with meaning, "fasted" connects modern medicine, wellness culture, and millennia of religious tradition.

Etymology of fasted
The underlying verb "fast" comes from the Old English "fæstan", meaning to hold oneself firmly from food, a term used in Germanic languages for religious abstinence long before it acquired dietary or medical senses. The practice of religious fasting spread through early Christianity from Jewish tradition, keeping the word tied to devotion for centuries. Its close companion "breakfast" emerged in Middle English as the literal "breaking" of the overnight fast. Today the word family spans both sacred observance and secular health practice.
