This is something that applies to holocaust survivors and hunger strikers.
I do agree that at 10 days (YMMV!) you probably don't need those crazy refeeding ramp-ups of broth and soups for 1-2 days then soft foods for another few days, etc, but also don't just stuff yourself until you cannot move! Since you can chose, take a couple of light/easy to digest meals before going back to normal.

Keep your phosphates ( and other electrolytes) normal and don't break the fast with lots of carbs
