proof of consumption

This receipt from a restaurant in Denver’s airport breaks down in detail the protein, carbs, fat, and calories for all of the food on a given bill by its percentage of recommended daily value (based both on a 2000 and 2500 calorie diet). Let’s put aside for a moment the norms that come from assuming that 2000 or 2500 is the “right” number of calories for a person to eat.

I’m curious how this receipt design could be rethought to account for groups of people (like families or couples) ordering together, or people with different optimal daily caloric intakes (like children or the elderly). 

Consider what would be required for this data to be seamlessly integrated into an ongoing tally of what you’d consumed and your levels of daily exercise, and the implications for hospitals and health insurers (not to mention fitness, meal plan, and exercise apparel companies).
