True. But calorie as a metric doesn't help either. It's too abstract. Instead, what if it were minutes? As in you'd have to walk for X minutes to burn off those super sized fries and shake. If a meals takes idk 4 hrs to burn off and you only have 3 extra hours in the evening...well, that would be better than calories.

Calories are a scientific unit. They don't work for every day people leading every day lives.
