I tend to eat smaller portions in LOS, too. Large meals and high fat and carbo loaded foods like the Big Mac, Fries, etc. do not go down well in that climate. I eat more fresh fruit and seem content with smaller portions. {I also tend to drop a few pounds in summer here in the USA, too.} It adds up to a smaller waistline on the way back from LOS than I had on my outgoing flight.
