'high-carbohydrate' originates from the combination of 'high' and 'carbohydrate', where 'high' indicates a large amount and 'carbohydrate' refers to organic compounds consisting of carbon, hydrogen, and oxygen.

The term 'high-carbohydrate' evolved from the need to describe diets or foods with a significant carbohydrate content.

Initially, it meant 'containing a large amount of carbohydrates', and this meaning has remained consistent in modern usage.
