Definition

A person's appetite or stomach's ability to digest.

colloquialhealthfood

How it's used

Refers specifically to the traditional Chinese medicine concept of excess heat in the stomach, which manifests as an insatiable appetite or rapid digestion. While it describes a physiological state, it is frequently used in casual conversation to explain why someone is eating an unusually large amount of food. It carries a slightly medical undertone but is common enough to be used when teasing friends about their hunger.

Examples

His appetite has been very strong lately, he feels hungry all the time.
Is your appetite too strong, that is why you never feel full no matter how much you eat?

Common phrases

having a strong or excessive appetite
having a big appetite

Common mistake

Do not confuse this with simply being hungry or having a big appetite, as it implies a specific internal imbalance. Using it to describe a normal healthy appetite can sound like you are diagnosing the person with a medical condition.
