Optimal foraging theory (OFT) is a model that helps predict how an animal behaves when searching for food. Although obtaining food provides the animal with energy, searching for and capturing the food require both energy and time. The animal wants to gain the most benefit (energy) for the lowest cost during foraging, so that it can maximize its fitness. OFT helps predict the best strategy that an animal can use to achieve this goal.
