I watched a BBC programme the other night and some chap had done reserch which led him to think that there's a "food clock" which can be used to more rapidly reset the body clock.
In one of the segments, a racing driver who regularly commutes from the UK to the US fasted before he got on the plane, had nothing but water, and ate a hearty meal at the first mealtime after arriving back in the UK. Anecdotally he said he felt better, but I guess there's more research to do.
