Diet on Target Day

I have my diet down pretty good for getting defined for a photo shoot, high protein, low carbs, then carb up 3 days before shoot, cut water intake day before, etc. But, what is a good diet to eat on the day of the photo shoot, and for several days afterward, as the photo shoot may last several days. So, what do I eat to keep my ripped and muscled physique for 4 to 5 days?

Just trying to keep this alive.
