What criteria, besides chronology, must a meal meet to truly earn the title of "main meal"?
Answer
Satiety and nutritional completeness
For the first meal of the day to functionally operate and be designated as a 'main meal' rather than just a starter, it must fulfill specific biological and physiological requirements beyond just being eaten first. One critical factor is satiety; the meal must provide lasting fullness to bridge the gap until the next planned eating interval without inducing hunger pangs prematurely. Furthermore, nutritional completeness is essential, meaning it must offer a balanced profile of macronutrients necessary for sustained bodily functions, as opposed to just a transient burst of energy from simple sugars.
