If you know better newsgroups to send this query to, please tell me.
Although the quality of postings in a couple of these I'm posting to
now has deteriorated badly in recent weeks (months?), truly
knowledgeable people have in the past offered good information and
expert opinion, and they may still be lurking in the wings.

Like many other animals, humans are said to gain weight in the winter,
lose it in the summer.

Does anybody out there know of systematic, quantitative studies of
seasonal weight changes in humans?

If broken down by age, sex, etc., it would be nice; but even some grand
"average" of winter vs. summer weights would be helpful.

Too much to ask for, but I'll ask anyway: besides AMOUNT of winter
weight gain, any good data on nature of weight gain, i.e. winter vs.
summer body composition, fat or muscle vs. water retention, etc.??
