Skinny vs. Lean: What's the Difference?

Edited by Aimie Carlson || By Harlon Moss || Updated on November 25, 2023
Skinny refers to being very thin, often with little body fat or muscle mass. Lean refers to having a low body fat percentage, typically with visible muscle definition.

Key Differences

Skinny refers to having a very slim body, often lacking in both fat and muscle mass. Lean, on the other hand, implies having a low body fat percentage while maintaining a good amount of muscle mass.
The term skinny does not necessarily indicate health or fitness, as it simply describes a body type that is slender. Lean, however, is often associated with fitness and health, as it suggests a well-maintained balance of muscle and minimal fat.
Being skinny can be a result of genetics, diet, or lifestyle, and doesn't always reflect physical strength or fitness. Being lean typically results from specific fitness regimens and diets aimed at reducing fat while building or maintaining muscle strength.
In popular culture, skinny is sometimes used to describe a desirable body type, but it can also carry connotations of being underweight or lacking in strength. Lean is generally used in a positive context, especially in fitness and health discussions, implying strength and good health.
Skinny can sometimes be used in a derogatory sense, implying that someone is too thin. Lean, however, is almost always used in a positive light, indicating a healthy body composition with muscle tone and low fat.
