On 2 Oct 2017, Jeffrey Hall Michael Rosbash and Michael Young won the Nobel Prize in physiology and medicine for the discoveries of molecular mechanisms controlling the circadian rhythm and work on biological clocks.

All the organisms including humans operate on a 24-hour rhythm that controls not only sleep and wakefulness but also the physiology. This is a great recognition for the field of circadian rhythm, an area that is intimately linked to our health. 

The human body responds physiologically to the circadian cycle of nature. The seasonal changes, the full moon day, and the new moon day have a direct correlation with our body’s chemistry. This is the reason why there is a need for modification in our diet.

Here are some things about the biological clock that you might not know: 

There exists an invisible biological clock that functions in our body. It is related to the nutritional changes and deficiencies which demand the right nutrients through daily diet.

When the sun rises in the morning, our calcium and glucose levels in the blood, in particular, go down.

Therefore, there is a need for a proper breakfast. Hence, the breakfast must thus include milk or milk products and any cereal which generates glucose after its metabolism. It is suggested that 20 percent of the whole day’s calories should come from breakfast to be taken between 8:30 and 9:30 am.

When the sun is right on the top, the secretion of juices in the intestine is at its peak. Therefore, a major portion of our total dietary intake of the day should be in the afternoon between 12 to 2 pm. This means that thirty percent of the entire day’s calories should come for lunch.

By evening that is between 5 to 6 pm, the calcium and glucose levels go down in our body like they do in the morning. So, our body demands light snacks like cereals with milk or milk products. This meal should give about 15 percent of the whole day’s calories.

In the night, the body is in a fix position and there is a rise in secretions. This is why the digestive system becomes slightly sluggish. This is the reason why the diet needs to be light and easily digestible two hours before going to bed.

In this case, one should avoid eating oily and spicy food. Fruits, curds, and buttermilk precipitate the secretions. Hence, they should be included in your dinner. 25 percent of the whole day’s calories must be obtained from dinner taken between 8 to 9 pm.

Rest five percent calories is from morning tea and five percent from bedtime milk. Thus two square meals and snacks and twice milk constitute a balanced diet.
