Recently Japanese food has westernized and rapidly the body fat percentage of office workers is growing.

We made a mobile service that can measure calorie consumption in real-time trying to grab their attention.Only five minutes walking can burn body fat and 350m is the average distance of a five minutes walk. A 350ｍ fat burning track advert tried to make office workers understand calorie consumption. There were various food items placed along the track representing how many calories they have burnt on their walk to work.
