The motivation for our project “CAL” is to reward people who manage their calorie consumption and exercise. Weight control and exercise are beneficial to our health, but they are also beneficial to the society, as this translates into billions of dollars of savings in medical bills. Promoting and rewarding calorie management seems to be a mission of justice and substance for people and the health service providers all alike. So, it makes sense to reward those who exercise and manage calories daily and continuously.
