For an individual starting work at 6:00 AM who eats a substantial break at 10:00 AM, what is the 10:00 AM intake functioning as?
Answer
Their functional main meal in terms of fuel contribution
In scenarios involving non-standard work schedules, the label applied to an intake often lags behind its actual energetic role. For someone beginning work very early at 6:00 AM, a small, light bite taken at 7:00 AM might satisfy the technical definition of 'breakfast' as the first consumption. However, if that individual then consumes their largest, most calorically dense food intake at a 10:00 AM break to sustain their demanding morning work, that 10:00 AM event functionally assumes the role of the 'main meal' based on the definition of providing the greatest fuel contribution for that period of activity.
