1. A method for determining an energy balance of a living subject, comprising the steps of:
- obtaining a signal corresponding to energy use of a subject;
supplying said signal corresponding to energy use to a calculating unit;
storing respective calorific values for different foods in a memory accessible by said calculating unit;
entering information identifying nutritional intake of said subject and obtaining a calorific value of food comprising said nutritional intake from said memory and supplying said calorific value to said calculating unit; and
in said calculating unit, calculating a signal representing an energy balance of said subject from said signal corresponding to energy use and said calorific value of said nutritional intake, and displaying said signal corresponding to the energy balance.

Abstract
In a method and apparatus for determining the energy balance of a living subject on the basis of the energy use and on the basis of nutrition intake, the energy balance is calculated on the basis of a determined energy use of the subject and on the basis of an input of the nutrition intake of the subject via an input unit. This calculation takes place in a calculating unit supplied with a signal corresponding to the energy use, using a value of the calorific value of the food that can be obtained from a memory. A signal corresponding to this energy balance can be generated on a display unit.
