A smart beverage container may be used to monitor user hydration. The container has at least one sensor for sensing an amount of liquid within the container. The liquid is monitored over time to determine an amount of liquid consumed by a user, and feedback is provided to the user indicating whether the user's liquid consumption is within a desired range according to a predefined profile of consumption. Such feedback may include information for indicating when the user is to consume additional liquid in order to remain in compliance with a desired liquid consumption regimen, as well as reminders to take additional liquid or warn the user if too much liquid had been consumed.
