To Fast or Too Fast can be confusing because “to” and “too” sound alike but have different meanings and grammatical roles. One expression refers to the action of going without food, while the other describes excessive speed. Understanding this difference helps you choose the correct expression and avoid a common spelling mistake in everyday English writing and conversation.
Comparison Overview
To fast and too fast sound almost identical, but they are used in completely different situations. The main difference comes from the words to and too, which have different meanings even though they can sound the same when spoken.
To fast means to abstain from food for a period of time. In this expression, to is normally the infinitive marker used before the verb fast. For example, “I plan to fast tomorrow” means that the speaker plans not to eat during a particular period.
Too fast means excessively quickly or at a speed that is greater than appropriate for a particular situation. For example, “The car is going too fast” means that the car is traveling at an excessive speed.
| Expression | Meaning | Grammatical Function | Example |
|---|---|---|---|
| To fast | To abstain from food | To + base verb | I plan to fast tomorrow. |
| Too fast | Excessively quickly | Adverb + adverb | The car is going too fast. |
In To Fast Or Too Fast, the key is to consider the sentence’s meaning rather than relying on pronunciation. If the sentence concerns avoiding food, to fast is appropriate. If it concerns excessive speed, too fast is correct.

How Each Term Is Used in Sentences
To fast follows the infinitive pattern:
to + base verb
For example:
- “I decided to fast tomorrow.”

For example:

Common Mistakes Learners Make
One common mistake is writing:
“I want too fast tomorrow.”
This is incorrect if the intended meaning is that the person wants to abstain from food. The correct sentence is:
“I want to fast tomorrow.”
Another common mistake is:
“The car is going to fast.”
If the intended meaning is that the car is traveling excessively quickly, the correct sentence is:
“The car is going too fast.”
These mistakes happen because to and too sound alike. Understanding their meanings helps prevent them.
Simple Rules to Remember
Use to before a base-form verb when you need an infinitive.
Examples:
- to eat
- to sleep
- to learn
- to fast
Use too when you mean excessively or more than appropriate.
Examples:
- too fast
- too slow
- too expensive
- too difficult
A useful memory trick is to replace too with excessively. If the sentence still has the intended meaning, too is probably correct.
Quick Tips for Writing and Speaking
Do not depend on pronunciation when choosing between to and too. Instead, look at the meaning and grammatical structure.
If you are talking about abstaining from food and need an infinitive, choose to fast.
If you are describing excessive speed, choose too fast.
When proofreading, ask yourself whether too means “excessively.” If it does, use too.

For example:
- “I decided to fast tomorrow.”

- “You are speaking too fast.”
- “The student is reading too fast.”
- “The process is developing too fast.”
- “The child is running too fast.”
The correct expression depends on what you want fast to mean.
When NOT to Use Each One
Do not use to fast when you mean that something is moving excessively quickly.
For example, this sentence is incorrect when describing excessive speed:
“The driver is going to fast.”
The correct sentence is:
“The driver is going too fast.”
Likewise, do not use too fast when you mean that someone intends to abstain from food.
Incorrect:
“I want too fast tomorrow.”

“I want to fast tomorrow.”
