Answer:
If calories were priced and added up per meal, it would likely impact people's eating habits. Charging per calorie would make people more aware of the actual cost of their food and may encourage them to make healthier food choices. People would be more inclined to choose healthier and lower calorie options, such as vegetables, fruits, and lean proteins. On the other hand, they might think twice about high-calorie, high-fat foods that are often seen as cheap and easily accessible, such as fast food burgers and fries. However, it's also possible that some people would continue to make unhealthy food choices, despite the added cost, because they may value taste and convenience over health. Additionally, charging per calorie may be difficult to implement in practice and could potentially lead to socioeconomic disparities in access to healthy food options. Overall, while pricing per calorie may have the potential to change people's eating habits, it would likely require a broader cultural shift in attitudes towards healthy eating and access to healthy food options.
