Hmm, as many answers as people I think!
For what it's worth, you'd have to be out hunting (ie daytime) before you got your antelope dinner - which implies nightime eating.
However you might be able to function during the day better with some food in you. Although thinking logically, in that case all your blood would be heading for your intestines rather than your brain...
Personally speaking I can eat a big lunch and forget about dinner, so for me 11-12 in the day would be best - just to be awkward!
I'd try a night time meal to start with and see how you feel. You can always change. Good luck!
