The food we eat, not only nourishes the body it affects its internal biological clock, which regulates the daily rhythm of many aspects of human behaviour and biology.
Whether you're feeling hungry at meal times, feeling sleepy during late night hours, or feeling awake every morning...all of these are normal and natural behavior of all living things.
