It does not significantly affect the circadian rhythm.
No, it shouldn't. Jet lag is the disruption of your circadian rhythm (your body clock) by the different time zones. So yeah, fasting shouldn't prevent jet lag.
Circadian rhythm sleep disorder is a disorder that affects the timing of sleep. People with this disorder typically have issues waking up by alarm clock but can sleep and wake when they wake by their body clock. You can get more information about this disorder at the Wikipedia.
Jet lagis also known astime zone change syndromeordesynchronosis. Jet lag can occur when people travel rapidly from east to west, or west to east on a jet plane. It is a physiological condition which upsets our body's circadian rhythms - hence, it is classified as a circadian rhythm disorder. Jet lag symptoms tend to be more severe when the person travels from westward compared to eastward.

Jet lag refers to the adjustment that the body must got through to recover from the interruption in the circadian rhythm which governs our sleep patterns. This usually occurs after a long commercial flight.
Jet lag usually lasts 24-48 hours after travel has taken place. In that short time period, the body adjusts to the time change, and with enough rest and daytime exposure to sunlight, it returns to normal circadian rhythm.
Circadian rhythms are a living organisms day/night cycles, daylight interacting with body hormone chemistry.
Extra doses of vitamins A, C, and E, as well as zinc and selenium, two days before and two days after a flight help to alleviate jet lag. Melatonin, a hormone which helps to regulate circadian rhythms, can also help
Jet lag can be overcome by using a "Happy Light". This is also known as a SAD lightbox, used for Seasonal Affective Disorder. These full spectrum lights help readjust your circadian rhythms.
Normally, all the regulating chemicals follow one another in order like threads in a weaving pattern. Every morning the sunlight resets the cycle, stimulating the leading chemicals.
Jet lag is a temporary disruption in the body's circadian rhythm caused by rapid travel across multiple time zones. It often leads to symptoms such as fatigue, sleep disturbances, difficulty concentrating, and gastrointestinal issues. The body requires time to adjust to the new time zone, and adopting strategies like adjusting sleep patterns and exposing oneself to natural light can help alleviate the effects of jet lag.
