I wonder if this much of a body fat gain and loss would actually
be typical for humans. Do they have any information on this?

I can confirm this from my own experience. I like to read in the
evening, but after 9:00 the carb cravings do kick in. Yet I
never wake up with carb cravings in the morning (or with any
hunger at all, for that matter). There's something odd about
going to bed with intense carb cravings, but waking up with no
desire for any food.
