refuel

This term is primarily used in technical or logistical contexts involving machinery, aircraft, and vehicles. It carries a neutral, functional tone, emphasizing the necessity of replenishment to maintain operation. In these contexts, it is often used both transitively, focusing on the object being filled, and intransitively, focusing on the act of stopping for fuel.

When applied to humans, the word is used metaphorically to describe the consumption of food or drink to regain physical or mental energy. This usage is common in sports or high-stress environments and is slightly more informal than the technical sense, though it remains a standard way to describe energy restoration.
