                                While the average adult male needs approximately 2,500 kcal daily and an average woman 2,000 kcal, there is no single maximum calories needed per day that applies universally. The highest caloric needs are typically observed in elite athletes or individuals with extremely physically demanding jobs, with some reports noting intake between 8,000 to 15,000 calories in extreme cases.
