A hydration and nutrition system includes a pressurized reservoir adapted to hold a quantity of fluid, a tube in fluid communication with the reservoir, a flow meter adapted to measure and collect flow data regarding the flow of fluid through the tube, one or more user performance sensors that provide performance data, and a database including a baseline requirements and a consumption plan. The baseline requirements are associated with a peak performance power output, and the consumption plan is based on a percentage of the baseline requirements for the peak performance power output. The system further includes a computerized nutritional calculator that performs the steps of receiving performance data, adjusting the consumption plan based on the performance data, calculating an actual caloric intake of fluid consumed, calculating a required caloric replenishment rate, and displaying a required caloric replenishment rate.
