The total caloric intake on a food label is based on how many calories?

It is based on a 2000 calorie diet.

Explanation:

Overall the total calorie intake that a healthy adult body needs to have per day depends on many factors such as height, age, weight, among others. But generally, a healthy adult should eat a total of 2000 calories to maintain proper nutrition for their body. This amount of calories is used as a basis for many diets, and is used as a basis, including for total caloric intake on food labels, to show how many calories of each food ingredient would provide 2000 calories a day.
