Starving for half a day can help you ease into adapting into a new time zone. Harvard medical school scientists revealed that the ingestion schedule is very important for the human body as is the habit to sleep at night. Significant changes in time zones can be difficult to adjust to. Generally, the organism takes at least four days to adjust to the change, even if it gets daylight change as its only orientation. Therefore, the only efficient recommendation for travellers is to calculate the nearest time for breakfast, and not to eat food for around 12-16 hours until then. This seems to be the only way to reduce the adaptation period up to one day.
The Harvard Medical School scientists say that starvation as recommended will contribute to the setup change of the human body, which is like the ability of all living creatures to accommodate in extreme living conditions. So if a person has changed several time zones and does not put his body into critical and exhaustive conditions, will find he feels quite healthy and will possibly only suffer from the wish to sleep at day and be active at night.
Keep in mind however, that this organism which is usually accustomed to receiving nutrition 5-6 times a day, and has now been left sans food for at least half a day, will only enter into extreme adaptation mood. The only way to combat this is to combine the first breakfast after a significant nutrition break and at the beginning of a new day, the adaptation process to the new time zone should be completed and make you feel fresh and ready for a new day.
