I do not know if this has anything to do with anything, but I do know that warmer weather affects how much I eat. Whether summering in Italy or in hot weather in the US, I don't experience hunger the same way as when I am in cold weather. My guess is my body does not need as much energy to generate heat, and I tend to drink much more water (sweating) than have a desire for food. Of course, this is my personal experience and genetics and does not explain obesity rates in hotter parts of the US (unless rather than water people are drinking Coke).
