There is a study out there somewhere to support anything you wish. Go by what YOU feel is right, what works for YOU.
Personally, I've done both and not on purpose.
When I was working crazy hours, I'd run out the door, grab a coffee, grab whatever garbage was around during the day (restayrant food), then get home around 9pm and order in. So yeah, I was eating late and I did gain weight, but it was under the worst circumstances.
Right now, as I pay attention, and listen to my body-starting with a big meal and tapering off throughout the day works best for me-makes me happy.
I have a friend who does the opposite and her family is a bunch of skinny happy campers.
I also think your suggestion of having a bedtime snack is way different then eating a full fledged dinner right before bed.
Back to what the studies say, since you asked. I have read that if you do have a snack, it should be protien based as carbs tend to inhibit the body's hgh production while we sleep-but you'll notice that's the opposite of what another poster said--you can literally make yourself crazy with 'studies'
So, have the snack, see how it goes, adjust if necessary.
Good luck
