The present invention relates to the area of lifestyle devices and applications, particularly to daily trackers of activities, such as pedometers used for exercise monitoring, and working in collaboration with tools analyzing and planning the food intake and amount of exercises to keep or obtain the desired weight. This invention aims at better controlling: fitness level, food consumption, blood glucose level and weight of a person throughout the day. For daily and weekly tracking of the weight, the ingested and expended calories are reported. Calories meal goals are adjusting daily reflecting the over the goal exercise levels as well as mismatch in food consumed and meal goals. The method for better blood glucose control predicts the effects of the food ingested on raising a post-meal blood glucose level, and suggests a suitable timing and the duration of the exercise following the food intake to minimize a post-meal blood glucose peak.
