Many people search for “Fast or Fasting” because the words look similar and come from the same root. They sound almost the same, but they are used in different ways.
The confusion is not about spelling. It is about grammar. For example, “I will fast tomorrow” and “I am fasting tomorrow” both talk about not eating, but the structure is different. One is the base verb. The other shows an action happening now.
Searches increase during Ramadan, Lent, and popular health trends like intermittent fasting. Students, writers, and content creators want a quick, clear answer.
Here is the simple truth:
Fast is the base form of the verb.
Fasting is the -ing form used for continuous action or as a noun.
This guide helps you understand the difference quickly and use the correct word with confidence.

The Origin of Fast or Fasting
The word fast comes from Old English fæstan. It meant “to hold firmly” or “to observe religious abstinence.” Over time, the meaning focused more on not eating for a period of time.
In early Christian history, fasting was common. It was practiced during seasons like Lent. In Islam, fasting is central during Ramadan. In Judaism, fasting is observed on Yom Kippur. Because of this strong religious link, the word has been used for centuries.
The word fasting developed naturally by adding “-ing” to the base verb. English often adds “-ing” to show continuous action:
- Eat → Eating
- Pray → Praying
- Fast → Fasting
There is no spelling difference between British and American English for these words. The variation is grammatical, not regional.
Today, fasting is also popular in health trends like intermittent fasting. This modern usage has made the word even more common worldwide.
