US researchers say that too much drinking and eating is almost the same as jet lag of our body clock.
A study that was published in the Journal Proceedings of the National Academy of Sciences showed that when normal laboratory mice were given food during their regular sleeping hours they adjusted their food clock. They would therefore wake up from their forty winks and would get ready for food.
On the other hand, another set of mice that were lacking the protein PKC could not respond to the changes in their meal time and therefore they slept through their food time.
The circadian oscillator or master clock completely controls our biological clock by keeping a track of biological processes and time.
