L'activité physique et l'alimentation, produisant des effets opposés sur le bilan énergétique, concourent tous deux au maintien de l'état de santé, et en particulier, participent à la prévention et au traitement des principales pathologies liées à la nutrition (obésité, diabète, maladies cardiovasculaires…). Dans ce domaine, nous pouvons identifier quatre enjeux majeurs

Physical activity and diet, while producing opposite effects on energy balance, work together for health maintenance, and especially are involved in the prevention and treatment of major chronic diseases such as obesity, diabetes, cardiovascular disease… In this field, we can identify four major challenges

• to really integrate the dimension of physical activity in our thinking and action in nutrition
• to better measure physical activity in everyday life, especially with more objective instruments than questionnaires
• to better describe and understand relationships between physical activity, dietary intakes and other health behaviors involved in nutrition-related diseases
• to evaluate the relevance of current physical activity recommandations for the general population as applied to the field of prevention and treatment of nutrition-related diseases; to evaluate how physical activity counseling might be most effective in this setting
