追答Why 3 meals a day?
I was talking with my co-workers about different diets that advocate eating X numbers of meals a day,and all their reasons when we ended up wondering,who set the standard of eating 3 meals a day?Where did it start?
I have not been able to find a good reason from google,however I did find many nutritional sites that agree that there's real reason to have 3 meals a day.
