Abstract
A nutrition tracking system comprises a nutrition tracking server, a plurality of weight-based food offering terminals, and one or more nutrition and meal information inquiry terminals. Multiple weight-based food offering terminals may be equipped on a food service cart. Each weight-based food offering terminal may be initialized to offer a type of food. The weight-based food offering terminal automatically measures the weight of food taken by a customer or for a customer, calculates the cost of food, and shows the weight and the cost on the display in real time. When the food is paid, the weight-based food offering terminal automatically reports the vending information to the nutrition tracking server. The nutrition tracking server maintains a database for customer meal information and a database for customer nutrition information. Customers may inquire their meal history and nutrition information using the nutrition and meal information inquiry terminals.
