  • the present invention relates to a calculator for assisting a person on a diet. s
  • Slimming diets have become extremely popular and many regimes have been proposed. Many such regimes are based on the simple proposition that in order co lose weight, a person must eat food having fewer calories than she/he 10 requires. The number of calories required by an individual is determined by his/her weight and level of activity. A heavy or active person requires more calories than a light or inactive person.
  • BMR basal metabolic rate
  • the present inventors have established that merely "counting calorics" is not O ideal and chat other factors should be taken into account. However, taking into account additional factors requires the dieter to perform more complex mathematics which is difficult in the bustle of daily life. It is an arm of the present invention to provide an apparatus whereby a diet regime, more complex than mere "calorie counting", can be readily adhered to.

Abstract

L'invention concerne un calculateur (1) destiné à aider des personnes à suivre un régime dans lequel elles se voient attribuer un nombre maximum quotidien de points à atteindre, ces points se rapportant à la valeur calorique et à un autre paramètre de la nourriture ingérée. Ce calculateur (1) comporte des moyens (6, ..., 22) permettant à l'utilisateur ou à l'utilisatrice d'introduire une valeur calorique et une valeur concernant l'autre paramètre, par exemple le poids en grammes de graisses saturées. Le calculateur (1) calcule ensuite les points relatifs aux données introduites. Cette valeur en points peut être soustraite d'une valeur 'points restants' pour donner à l'utilisateur ou à l'utilisatrice une indication des points qu'il lui reste pour la journée en cours. La teneur en fibres alimentaires peut également être introduite comme autre paramètre.
