Thick vs. Fat: What's the Difference?

Edited by Aimie Carlson || By Janet White || Published on December 15, 2023
"Thick" describes something with substantial depth or density, while "fat" often refers to the excess bodily tissue or richness in food.

Key Differences

Thick is used to describe an object's width or depth relative to its other dimensions, implying a considerable extent from one surface to its opposite. Fat, however, is typically used in the context of living beings, referring to the accumulation of excess flesh.
In the context of materials, thick suggests a substantial or dense structure, like a thick book or a thick layer of paint. Fat is less commonly used in this context but can describe richness or abundance in composition, like fat in food.
Thick can also describe a consistency that is dense or not fluid, as in thick soup. In contrast, fat is often used to describe the nutrient found in food that is essential for a balanced diet but can be unhealthy in excess.
In figurative language, thick can describe the atmosphere (thick with tension) or understanding (thick-skulled). Fat is sometimes used metaphorically to imply abundance or excess, as in a fat paycheck.
Thick generally has a neutral or positive connotation in various contexts, while fat can have negative connotations, especially when referring to body size, and should be used sensitively.
